When the Nighloks are revived and begin to attack the mortal realm, Jayden of the Shiba Clan takes arms to fight them as the Red Ranger. After defeating the company of Moogers, Jayden is informed by his mentor, Ji, that he must assemble his team of Samurai Rangers instead of fighting on his own. Meanwhile, on the Sanzu River, the incredibly powerful Master Xandred finally awakens. Upon learning that the Samurai Rangers still exist, he becomes enraged and sends the Nighlok Tooya to attack the humans with an army of Moogers. Ji summons four other warriors: Olympic swimmer Kevin, kindergarten teacher Mia, carefree gamer Mike, and pure-hearted country-girl Emily. Upon meeting the four, Jayden gives each one a chance to back out of his crusade, and when all four decline, he gives each one a Samuraizer phone. Jayden, Emily, Kevin, Mia, and Mike then take on Tooya and his numerous Moogers. Red Ranger defeats Tooya, but despite that, he tells his teammates to remain on their guard. Sure enough, the Nighlok is reborn as his secondary form, a titanic mega-monster, so the Samurai Rangers enlarge their Foldingzords to confront and destroy him. After the battle, Ji welcomes Emily, Kevin, Mia, and Mike into the Shiba House. All five warriors become full-fledged Power Rangers.

After joining Jayden as his teammates, Emily, Kevin, Mia, and Mike begin their transition into Samurai Rangers. However, while Mike spars with Kevin, Emily disappears. Kevin, Mia, and Mike discover her practicing at a nearby park, revealing her reasons for becoming a Samurai Ranger. Meanwhile, Bulk is reunited with Spike, the son of his best friend Skull, and he becomes committed to training his nephew into becoming a samurai. When the Nighlok Scorpionic appears, four of the Samurai Rangers deal with the Moogers while Red Ranger fights the new Nighlok. During the battle, Red Ranger keeps a young girl out of harm's way before the Rangers defeat Scorpionic with their combined Spin Sword attacks. But when Scorpionic revives into a Mega Monster, the Rangers combine their Foldingzords to form the Samurai Megazord to destroy him and his giant Mooger army. After the battle, Ji congratulates the Rangers while Mike uses his symbol ability to create confetti before dancing all over the house.

The Samurai Rangers, are seen training, but Mike can't seem to sense Jayden or Kevin's attacks. Mike soon leaves practice to hang out with his friends, telling them of his struggles. However, the city is attacked by the Nighlok Rofer, sent by Xandred to raise the Sanzu River's water levels with human fear. Even in his Ranger form, Mike is no match for Rofer as the others arrive as the monster falls back to rehydrate in the Sanzu River. Jayden explains to Mike that being a Samurai Ranger is the ultimate sacrifice and must stay away from his friends and family to protect them. After giving it thought, Mike gets an idea and starts to train himself as Jayden undergoes his training. The next day, when Rofer resumes his attack, Mike again takes on the Nighlok on his own, tricking him into tangling up his elongate arms. Mike then executes the finishing move. When said Nighlok is revived and enlarged, despite Mike's intent to finish him off himself, the Rangers form their Megazord and use Jayden's training to finish the monster off.

After confronting the Nighlok Doubletone, the Rangers search for the young boy whom the monster was talking to, a little leaguer named Ryan. Kevin and Mia find the boy only to refuse to answer them as he runs off. Following him to his home to learn whatever secret he has, the two get into a discussion of Kevin's regret of his life-long dream that he has been keeping to himself before Mia assures him he'll live his dream once Xandred is defeated. After an all-night stakeout, Kevin and Mia find Ryan as he suddenly disposes of his baseball stuff and calls Doubletone as he performs his promise, hurting himself so he cannot play baseball to get his father back. However, as the garbage truck arrives to take out the trash, Doubletone revealed it to be a lie as part of his plan to make the boy give up his dream to raise the Sanzu River. Vowing to make the Nighlok pay, Kevin and Mia fight him as the others arrive, defeating Doubletone as he revives into a giant before Samurai Megazord destroys him. Later, the Rangers attend Ryan's game after the boy learns the sanitation worker saved his stuff and gave it to his coach, with Jayden using his Symbol Power to make Ryan's dream a vision for a short while.

While the others spend their leisure time at the Rainbow's End amusement park, Jayden remains behind to master the use of the Beetle Disk as the rest of the team encounter the Nighlok Dreadhead, whose flexible body and marksmanship overpower them. Even with the Red Ranger's arrival, the team is no match for Dreadhead before he falls back when he begins to dry up. After revealing the Beetle Disc to the others, Jayden resumes training into the night, nearly destroying himself in the process. The next day, a rehydrated Dreadhead resumes his attack with the other Rangers arriving to fight him as Jayden arrives and succeeds in using the Beetle Disc to have his Fire Smasher assume Cannon Blast Mode to destroy Dreadhead. When Dreadhead resurrects into a giant, he overwhelms Samurai Megazord until Jayden uses the Beetle Disc to summon the Beetle Zord. To counter the summoned giant Moogers, the Beetle Blaster Megazord is formed to take them out before destroying Dreadhead. After the fight, Jayden joins the others at the amusement park.

During battle training, Emily accidentally injures Mike in the arm, with Emily's attempts to care for his arm making a mess of everything. The Nighlok Negatron appears and subjects his victims to insults that hurt their feelings so deeply that the verbal abuse becomes a physical assault. Confronting him, all the Rangers are struck down by Negatron's attacks save for Emily, who is unaffected as the Nighlok is forced to retreat. When her teammates wonder about her immunity to Negatron's attacks, Emily tells them how her sister Serena taught her to ignore insults and how you need to keep thinking that the person never even said it. When Negatron resumes his attack, Emily weakens him with Mike's help as Jayden destroys him with the five-disc Beetle Cannon. Negatron revives as a Mega Monster, and the Rangers destroy him with the Beetle Blaster Megazord. Later, the Rangers are then seen walking along the sidewalk while Mike carries Emily, who loses consciousness at the end of the fight. Mia hears an ice cream truck and Emily, who has been faking unconsciousness for a few minutes, pretends to wake up so they can all get ice cream.

While having breakfast, the Rangers learn that the Swordfish Zord has been sighted off the coast as the noxious Nighlok Yamaror appears. While the others go after Yamaror, poisoned by his intense stench. As a result, Kevin is sent to acquire the Zord by fishing for it. But after failed attempts to catch it, Kevin receives the aid of a fisherman before being contacted by Ji and being told that the others got poisoned and the Swordfish Zord is needed to cure them. As Jayden slows Yamiror down despite the poison's pain, Kevin finally manages to fish the Zord out with the fisherman's help. After curing his teammates of Yamaror's poison before using the Fire Smasher's 5-Disc Swordfish Cannon mode to defeat the Nighlok, Kevin summons the Swordfish Zord to battle the mega monster before having it form the Swordfish Fencer Megazord. As the Rangers spent a day at the beach, a mysterious figure who witnessed the Rangers' fight with Yamiror walks off into the night.

Dayu and the Moogers start kidnapping brides, so the Rangers use a fake wedding to try to trap her. After she doesn't show, they make Jayden and Mia pose as another couple at a wedding, which leads to Mia being kidnapped. However, Dayu didn't notice the trap and also kidnaped the "real" bride, who turns out to be Emily, in disguise. After sending the replica symbol power Rangers into an ambush, the Rangers challenge Dayu to a battle in the nearby forest and quarry. However, after trying to destroy her, a new Nighlok named Deker shows up, and Jayden catches his attention. Dayu and Deker return to the Netherworld, but not before summoning Giant Moogers to finish the job.

Nighlok Madimot shows Master Xandred that he found and possessed the previous Red Samurai Ranger's Tiger Zord and claimed it as his pet. Madimot attacks in the forest, and the Rangers rush towards the Nighlok. Madimot fires a blast at Mike, but Kevin gets in the way and takes the blast. Kevin becomes possessed by Madimot, and Madimot orders him to attack the others. Kevin fights Jayden, and Jayden rushes towards Madimot, but he is forced to get Emily, Mia, and Mike out of there. Kevin and Madimot attack a construction site, and the Rangers arrive. Deker returns to his human form and watches the fight between Jayden and Kevin, with the other Rangers commenting on Jayden's abilities. During the fight, Jayden frees Kevin from Madimot's control, and the five then attack Madimot and destroy the Nighlok. Madimot returns as a mega monster and summons the Tiger Zord; the other Rangers get into their zords, and Jayden's Lion Foldingzord battles the Tiger Zord and frees it. With the Megazord fused with the Tiger Zord, They finish Madimot once and for all.

Jayden and Ji tell the others that the Tiger Zord, the Swordfish Zord, and the Beetle Zord can combine into the Samurai Battlewing, a bird-like Megazord, and they try to find a fitting pilot for each support zord. Jayden keeps the Tiger Disc, Kevin keeps the Swordfish Disc, and the Beetle Disc is given to Mia, much to Mike's dismay, making him jealous in the process. Mike starts to train harder than usual, but he thinks he can't catch up to Jayden and Kevin's progress. Then, when the Rangers face a new Nighlok named Desperaino, who uses the "loss of hope," Kevin attaches his Swordfish Disc onto the Hydro Bow to try to stop it. When Mia tries to attach the Beetle Disc onto her Sky Fan, the Nighlok knocks it away, and Mike catches the disc. Against the others' protests, Mike attaches the Beetle Disc onto his Forest Spear, but when Kevin and Mike try to launch attacks onto the Nighlok, the Forest Spear doesn't work, and the Nighlok gets away. After the battle, Ji scolds Mike for acting so foolish and jeopardizing the team's mission. Subsequently, after locating Mike at an arcade, Ji leads him to a clearing and tries to teach him about harnessing the Forest Symbol. Then, after another encounter with the Nighlok, Mike destroys him. After a final offensive on the enlarged monster by the Samurai Battlewing auxiliary Zord combination, the Rangers celebrate victory. Mia allows Mike to keep the Beetle disc. Mike creates a plant for Ji to symbolize their growing "friendship."

Master Xandred is troubled by how much Deker knows about his past and the Seal that defeated him. Furious, he called upon giant and standard Moogers to attack the city, destroying everything. Bulk and Spike encountered the Moogers and tried to put up a fight, but they end up running for their lives instead. The Pink Ranger rescues Spike, and he begins to develop a crush on her. The girls battle the standard Moogers while the boys take on the giant Moogers in the Samurai Battlewing. Later, a powerful new Nighlok named Robtish appears and challenges Jayden to a duel. The other Rangers follow on and are defeated by the Nighlok's power. When the Nighlok aims the Red Ranger, Deker appears, announcing that Red Ranger is his opponent. Then the Rangers fight in a triple threat match when the Nighlok ends up drying out and retreating to the Sanzu River. Jayden and Deker continue to fight, but Jayden is defeated, and he takes a minor blow. Mike calls for Ji to bring help so that Emily and Kevin can be brought back to the Shiba house. Back at the Shiba House, Jayden secretly leaves his comrades and goes on a journey alone to protect them.

Jayden leaves the Shiba House to keep the other Rangers out of danger. Meanwhile, Emily and Kevin start to feel better, and they worry about Jayden. Kevin tells the group that he had an idea of combining the Samurai Battlewing with the Megazord. In the Sanzu River, Octoroo says Master Xandred won't be happy when he finds out Jayden is still alive. Robtish replies he couldn't finish Jayden off because of a half-human, and Dayu (who is also half-human but with no human form) thinks it is Deker. Xandred awakens, angered by the fact Deker is "helping" the Rangers, and sends his Moogers to fight Deker. This leads him into getting into a fight with Deker himself. Jayden wanders around the city at night, and the next day, he finds a boy crying because he misses his father, who is currently at work. Jayden says that he misses his father, who is presumed dead after his final battle with the forces of Master Xandred. Jayden creates a paper airplane for the boy like his father did with him, and soon, the other children playing around make airplanes as well. Jayden says in his mind it should always be monster-free until Robtish and some more Moogers arrive. He fights them and is soon helped out by the other Rangers. Jayden now believes he needs his team to succeed. When Robtish turns into a mega monster after being destroyed by the Five-Disc Tiger Cannon, they destroy him with Kevin's new idea for the Battlewing Megazord, a Samurai combination of Megazord and the Samurai Battlewing.

Returning after what seemed to be a false detection of a Nighlok attack on the Gap Sensor, the Rangers find an arrow with a note on it that says "See You Soon." With Jayden sensing something from before within the house, it starts to haunt him. Deciding to investigate the Gap Sensor, the team encounter a fish-seller whose handwriting matches the note. After the seller gives them the slip, Kevin and Mia find Jayden while Emily and Mike track down the fish seller. Kevin and Mia find Jayden confronting the Nighlok named Vulpes, who was spying on Jayden to find the Shiba sealing symbol that sealed Master Xandred years ago. With his mirror medium destroyed, the Nighlok overwhelms the three with his magic as Emily and Mike arrive with the fish seller following. But even all five Rangers are no match for the Nighlok as they revert to normal. The fish seller arrives, transforming into the Gold Samurai Ranger. After taking out the Moogers in blinding speed, the Gold Ranger battles the Nighlok and destroys him. When the Nighlok revives, he overpowers the Battlewing Megazord until the Gold Ranger enters the fight in the Octo Zord to weaken the Nighlok so the Battlewing Megazord can land the deathblow. After the fight, Jayden reveals he already knows the fish seller as his childhood friend Antonio.

As Antonio heads to the Shiba House, the others listen to Jayden and Ji talk of young Antonio. Jayden gave him the Octozord and threatened to quit his training if Ji tried to take back the Octozord. Antonio makes an entrance, all fancy, but when his fish hook rips his pants, he feels embarrassed. Antonio explains that after moving away when he was a kid, he trained himself to be a samurai and built his Samurai-Morpher from a trashed cellphone to communicate with Octozord through text Zords understand the Rangers. They were born into the Samurai heritage. Ji, feeling that Antonio lacks discipline and true samurai training, confiscates Antonio's morpher, which he later doesn't react too well. Jayden agrees with Mentor, although Antonio begs Jayden with memories of childhood friendship. As the Rangers fight the Nighlok Steeleto (who vows to avenge his best friend Vulpes), they're powerless to destroy him. Steeleto retreats when he starts to dry up, and the team starts to consider bringing Antonio along. Antonio, down at the fishing pier, angrily talks with Octozord about regretting meeting the Rangers. Emily and Mike go to ask him to join and go to the mansion. There, Jayden is convinced to give Antonio back his morpher just in time for the next attack by Steeleto. When the Rangers arrive, Antonio struggling to get into a heroic position, they begin fighting, and Steeleto is overpowered when Jayden and Antonio tag-team it. Once Steeleto mega-sizes, Antonio combines the Octozord with the Samurai Megazord and defeats Steeleto. To celebrate, Antonio cooks fish barbecue, and everyone appreciates Antonio's membership.

Ji and Antonio announce that Antonio is fixing the Claw Zord damaged in battle long ago, and Ji hid it. Kevin doesn't fully accept Antonio as a "true Samurai" and thinks he's just goofing around. The monster of the day steals kids' toys to create sorrow with Octoroo, trying to find another way to open the Sanzu River through a well. Bulk and Spike are sleeping, and their toy panda is stolen, and all that is left is slime. Dayu visits Deker outside the Sanzu River, but around it, he's still injured. Dayu wonders if Deker does remember anything from his past. Antonio follows Kevin's morning routine to learn what makes him a true samurai. The boys end up in the forest finding Octoroo, but their morpher signals are blocked. Kevin and Antonio eventually overcome their differences and fight together to defeat the Nighloks.

A Nighlok begins to steal people's spirits to have them fall into a never-ending slumber; the Rangers search for a way to defeat their enemy without the help of the Yellow Ranger after the Nighlok can steal her spirit.

The rangers start in a battle in their Zords against giant moogers. Later, the Rangers talk about a way to stop the Nighlok when Ji and Jayden reveal the existence of the Black Box, a weapon made by the first Red Samurai Ranger with untold power. However, it was never finished, and no one has ever managed to complete it. Jayden doesn't think it's a good idea when Emily says that maybe Antonio could do it since he programmed the claw Zord even though he lacks the symbol power training and Jayden's dismay, they agree. Jayden takes The Rangers to the Tengen Gate, where they meet the gate's guardian, Daisuke, to hand them the Black Box. Daisuke tells the Rangers a folk tale about a Nighlok king who turned a woman and the man she loved into Nighloks. While Xandred is incapacitated regenerating in the Sanzu River, a Nighlok named Arachnitor tries to overthrow him and tries to force the sealing symbol from Jayden. Octoroo, because of Arachnitor, poisons Jayden as the Rangers sit for tea, trying to get the special sealing symbol from him. While Jayden is poisoned, the other Rangers face off against Arachnitor but are doing poorly without their leader. While the Rangers are distracted, Deker kidnaps Jayden when Antonio confronts Octoroo, planning on purging the poison in him in a nearby river so that they can finally duel. Before Arachnitor can finish the Rangers off, Xandred drags him back to the Sanzu River for trying to overthrow him. After all the Nighloks disappear, Antonio is left wondering what to do, with Jayden missing and his friends unconscious.

Deker uses the nearby river to purge the poison from Jayden so that he can recover enough to duel Deker. While Antonio tries to work on the Black Box, the others Rangers recover, leave their ranger discs for Antonio to access the Black Box, and end up fighting a mutated Arachnitor. At the Shiba House, Antonio tries to work on the Black Box. Still, before fully unlocking it, Antonio figures out where Jayden is and decides to help him as he does not have energy symbol energy to finish unlocking the Black Box yet. Antonio then convinces Deker not to duel Jayden until he is back to full strength and insists on a duel the following day, or he would release his Nighlok side on innocent people to force Jayden to agree to the duel. Jayden and Antonio join the other rangers to fend off Arachnitor, who flees before being defeated, leaving the rangers to fend off giant Moogers instead, which the rangers destroy with the Battlewing Megazord and the Claw Zord. Later, Jayden focuses on Deker's word to him before their impending duel with Deker, until the other rangers unknowingly make him realize that he can choose who he wants to be, despite what Deker had said.

Furious with Dayu for not following his orders to destroy Deker, Master Xandred set fire to her beloved harmonium when she was provoking him to destroy her. Devastated, Dayu escapes into the human world to fix it. Meanwhile, the Rangers face the Nighlok Rhinosnorus, who traps Dayu and Mia, and Antonio in a dream world. Jayden uses his symbol power to open a portal to the Dream World, allowing Kevin and Mike to enter, but severely exhausts himself in the process, preventing himself from tagging along. In the dream world, aside from Bulk and Spike's ridiculous fantasies of being samurai along with Antonio's dream of a fishing champion, Mia learns that Dayu and Deker were both once human, and the two humans are previously mentioned in Daisuke's story. After Rhinosnorus is defeated, Deker shows up to challenge an exhausted Jayden.

Continuing from the end of the last episode, Deker demands Jayden to duel him. Jayden tells Deker he only fights to protect the innocent and not out of amusement. Deker gives him 24 hours before the duel, or else his Nighlok side will start attacking innocent people, should Jayden fail to show up. Kevin and the other rangers try to talk Jayden out of fighting Deker alone instead of defeating him as a team. Jayden refuses and tells them he must be the one to duel Deker, or Deker will never give up. Just as Jayden prepares to leave the next day, Rhinosnorus attacks once more, and Jayden puts Kevin in charge of leading the team while he fights Deker. The Rangers defeat Rhinosnorus while Jayden battles Deker. The battle rages on, with both combatants evenly matched. Eventually, Jayden allows Deker to injure him to get close enough to finish Deker off. Deker's sword Uramasa is broken, and half of it gets stuck into the ground nearby. Deker thanks Jayden for the Ultimate duel, which has released him from his Nighlok curse, before vanishing in a puff of smoke. Back at the Shiba House, Jayden thanks Kevin for leading the team in his absence as they all celebrate their victory.

In the Nighlok afterlife, the defeated Nighlok Monsters hold a Halloween party and recap their battles with the Rangers to each other, which Master Xandred views from his mirror. All the Nighloks told their versions of how the Rangers took them down. After the stories, the Nighloks vow never to bring up the Rangers at their next Halloween party. At the end of the episode, Master Xandred is displeased at not being invited to the afterlife party stating "I would have been the life of the party." Octoroo states to Master Xandred that the party was meant for those "in the obituary."

In another dimension of Earth, the RPM Red Ranger Scott uses the Skyrev Megazord to fight Venjix's general Professor Cog in the deserts outside of Corinth. Cog tricks Scott into lowering his guard and then escapes the battle. In a subway within the Samurai Rangers dimension, Professor Cog and his Grinders enter the scene. In the city, the Rangers battle Sharkjaw and the Gold Ranger joins the fight, but he was late. Professor Cog is surprised to learn that Rangers exist in this dimension but dismisses them as mere pests. Sharkjaw retreats after drying up, and Octoroo tells him he is no longer needed as General Gut and his army of Moogers are waiting to attack in the human world. Professor Cog enters the Netherworld to meet Master Xandred. Professor Cog wants to use some of the Sanzu River to poison the humans in his dimension in return for the destruction of the Samurai Rangers. Master Xandred agrees to the plan. Back in the subway, the RPM Red Ranger makes his appearance. The Rangers are celebrating their victory with ice cream when they run into a swarm of Grinders. Their swords prove ineffective against the Grinders until Red RPM Ranger joins the battle and destroys all the grinders. The Rangers bring him to the Shiba House so that he can explain his story. Scott doesn't de-morph because he fears he might not breathe as he is more accustomed to the atmosphere of a protective biosphere from his dimension. Later the Grinders make their attack on Antonio, who morphs and fights the Grinders. The Gap Sensor alerts the Rangers to battle. Scott gets there early by taking Mentor Ji’s bike and helps out Antonio while the Rangers and Professor Cog enter the fray. Cog uses his hypno-bolts on Jayden and Scott (which will slowly cause them to distrust each other), and he uses his Portal attack to the other Rangers into his dimension. At the docks, Cog blasts the Red Rangers into the water and leaves. Jayden tries to help Scott, who gives him the cold shoulder. Jayden is worried about his friends, but Scott tells him that the Rangers will help them. Back at the Sanzu River, the Grinders start collecting the Sanzu River. At the Shiba House, Jayden and RPM Red Ranger meet up with Mentor Ji, who pinpoints Cog, Sergeant Tread, and General Gut. Jayden morphs into action and summons a horse while Scott takes the bike again. Both Rangers race to the scene. Scott is bitter that Jayden beat him to the scene, and the two Rangers battle each other as Cog watches. After a brief fight, the Rangers both appear unscathed, much to Professor Cog’s confusion. Mentor Ji had noticed the effect of the hypno-bolts and reversed the poison with symbol power. The Rangers were staging the fight to fool Professor Cog. The Red Rangers work together to fight the villains, powering up to Shark Attack (Scott) and Super Modes (Jayden). During the fight, the Rangers return to join the fight (courtesy of Dr. K and the RPM rangers) and defeat Professor Cog and Sergeant Tread. They then turn their attention to the Mooger army. The Rangers summon the warhorses and head towards the Mooger army while the Gold Ranger and RPM Red Ranger use a car. The Rangers work together to trim down the army size. Red Ranger faces off against General Gut, who knocks him to the ground. As General Gut is about to finish him off, Jayden uses the Shark Disc to defeat the swarm of Moogers, and together the Rangers defeat General Gut, who grows into his Mega mode form. After a brief battle, General Gut reveals his True form, which includes a Serpent monster attached to his body. The Rangers form the Samurai Shark Megazord to defeat him finally. Antonio and Scott watch from afar until Scott asks Antonio to help him fix the damaged car unless they want to walk it back. Back at the Sanzu River, Master Xandred is furious with the failure as Octoroo tries to calm him down. Back at the subway, Scott says goodbye to his new friends before wishing Mike good luck with Emily.

3. This television movie takes place during Power Rangers Super Samurai despite being aired as part of Power Rangers Samurai.

While reflecting on their first year together, the Rangers learn the meaning of Christmas. Emily reflects on the year through a letter to her sister Serena by writing about their adventures and fun times. Meanwhile, Bulk tries to make his first Christmas with Spike memorable and recap about their moments of comical relief, also their near encounters with the Rangers. The next morning on Christmas Day, everyone opens their presents except Mike. Feeling left out, Mentor tells him to go to the front door where Mike finds a green motocross bike. As he returns home, he tells the others that he gave the bike to these two guys who have nothing and are grateful for what he has the others. It turns out that Bulk and Spike are the guys that Mike gave the bike to, and they are last seen riding it chasing Santa in the night sky, wishing everyone happy holidays.

The Rangers become concerned by the extent of the Sanzu River when its water begins to seep into our world – meanwhile, Arachnitor resurfaces and uses the River's water to prevent himself from drying out. At the Shiba House, Antonio works on the Black Box – after he completes it, he rushes to where the other Rangers are fighting Arachnitor and finally arrives, informing Jayden that he has succeeded in unlocking the Black Box. Jayden uses the Box to access Super Samurai Mode and defeat Arachnitor. Once Arachnitor assumes Mega Monster form, they use a new Black Box-powered Megazord combination of Samurai Megazord and Claw Battlezord: Claw Armor Megazord to do battle with the summoned giant Moogers, and then a new cannon: the Samurai Battle Cannon, formed by the Beetle, Swordfish, Tiger and Octozords to destroy Arachnitor.

In a subplot, Bulk and Spike attempt to record the Rangers battling the Nighloks on film to learn some of their moves. But in a comical twist, they forget the SD card for the camera.

The Rangers must defeat Armadevil, a hard-shelled Nighlok who proves to be a formidable opponent. Meanwhile, Antonio loses his Samurai Morpher without knowing, and the two wannabe Samurais (Bulk and Spike) find it themselves. The Rangers combine their attacks in a certain order to weaken Armordevil's shell and Kevin uses the Black Box to finish him. In Mega Monster form, Armadevil's shell is fully restored and proves difficult to break. The Rangers then repeat their first method of defeating Armadevil, but it still is ineffective. The Samurais call the Samurai Megazord and Claw Zord for the Claw Armor Megazord, then the Samurai Battle Cannon, and finally finish the battle once and for all. Afterward, the wannabe Samurais put the Morpher in the exact spot they found it. Emily and Mike show up moments later, relieved at Antonio's safety, and return his Morpher from the ground. Antonio wonders what he missed all day.

This episode's Nighlok, Switchbeast, traps the spirits of Jayden, Mia, Kevin, and Antonio inside a fan (Mia), a (ballerina) music box (Kevin), a gnome (Jayden) and a yet-to-be-ate fish (Antonio – ironically, the soon-to-be-ate fish his spirit is in is the fish he was going to eat) while Emily and Mike try to defeat him to save the others. Switchbeast also traps people's spirits at a public market in some of the items they were selling, including the wannabe samurais: Bulk and Spike into a soda can and a newspaper. Switchbeast does this to have the humans "recycle" his victims without knowing it, which will cause the misery of the people he switched to raise the Sanzu River. Emily and Mike manage to switch the Nighlok's spirit with Mike to make him force the spirits of everyone back into their bodies – this works as even the Samurais return, but Antonio is traumatized when he escapes just as a neighborhood cat is about to eat the fish he was in. Mike goes Super Samurai and destroys Switchbeast, but with the Nighlok supersized, the Rangers must summon the power of the Claw Armor Megazord. The Rangers win and celebrate with their friends by having a barbecue. Meanwhile, Master Xandred is angered at this defeat and throws a Furry Wart out a gap – this Wart meets Dayu on a river stream as she plans to find a way to end Master Xandred's life by casting her out and breaking her harmonium.

After switching bodies with a fish and almost getting eaten by a cat, Antonio is now afraid of fish. Meanwhile, at the Sanzu River, this episode's Nighlok, Serrator, offers help to Master Xandred in his plans and reveals that he was the one who sent Switchbeast to Master Xandred. The Master is skeptical at first but when Serrator proves his loyalty to him, he is accepted. Back at the Shiba House, the team tries to help Antonio out with aversion therapy: Jayden is afraid of spiders, Mike is claustrophobic and Mia is afraid of frogs – after that attempt fails, the Gap Sensor goes off and the Rangers rush into action. Antonio stays behind and Mentor Ji shows him the LightZord, an ancient Zord that no Ranger has been able to master – he asks Antonio to see if he can unlock it. The Rangers deal with two Spitfangs before Serrator destroys them himself and personally tests the Rangers' fighting skills. He effortlessly defeats the Rangers in battle. At the last second, Antonio arrives with the Lightzord to drive Serrator off before he enlarges Lightzord to take out the Papyrox. Later on, the Rangers ask Antonio how he got over his fear – he tells them in response and they start to laugh as it is shown that Mentor Ji had snuck up behind Antonio and stuffed sushi in his mouth, having him eat it.

Bulk and Spike attempt to rescue the stray kitten from the top of a tree in a subplot but end up getting stuck there themselves.

At the Shiba House, with Antonio having conquered his fear of fish, Emily and Mike decide to keep the stray kitten as a pet. The Rangers are surprised to see Antonio and Mentor Ji working collaboratively to store the Shark Disk (capable of defeating General Gut) with the Light Zord. Mike plays a prank on a distracted Antonio by putting dry cat food in his plate of trail mix but is caught by Mentor Ji who gives Mike a taste of his own medicine before deciding to continue working on the Disk outdoors, free of distractions. Meanwhile, at the Sanzu River, Octoroo announces the return of the powerful Nighlok Eyescar to Master Xandred who has a plan to trap the Rangers. Upon completing the Shark Disk, Antonio and Mentor Ji are kidnapped by a swarm of Moogers. With the Gap Sensor sounding, the Rangers head to investigate their disappearance. While following the trail left by Antonio's dropped reel, the Rangers are ambushed by many Moogers. Mike figures out something within the Light Zord and unleashes it, which turns out to be the Shark Disk. This allows Jayden to access Shark Attack Mode to destroy the set of Moogers effortlessly. Eyescar eagerly awaits the Rangers' arrival with his massive Mooger army, outnumbering the Rangers a hundred to one. Still, Jayden, having to anticipate the situation, enters the fray with the Samurai Battlewing destroying most Moogers with an aerial assault. The Rangers then move in and rescue Ji and Antonio before defeating Eyescar together. When Eyescar returns to life as a Mega Monster, the Rangers use the Shark Sword to finish him off. Back at the Shiba House, Antonio and Mentor Ji thank the rest of the team for their help and Mike attempts to try the same prank again on Antonio, only to be caught a second time by Mentor Ji.

In a subplot, Bulk and Spike try to create signature symbols for each other.

Young boy Cody comes to the Shiba House with a Power Disk and orders The Rangers to break the seal on the Bullzord, the original Samurai Zord, which was sealed by the Grand Shogun 300 years ago after it ravaged the countryside. (The location of the Zord is a secret which Cody's family has guarded). The Rangers return Cody home to his father, who insists that as per the Grand Shogun's orders, the Bullzord is uncontrollable and must stay sealed for eternity. When neither his father nor Jayden helps him, Cody escapes his house and breaks the seal himself, unleashing the Bullzord which runs amok as feared. Meanwhile, Serrator sends Crustor to capture the Bullzord to use it in an unknown plot. Fearing for his son's safety, Cody's father gives Jayden the original Bull Disk as Cody had owned a fake. As the Rangers battle Crustor, Jayden manages to get Cody the Bull Disk, which tames the wild Zord, uncovering a secret message from the Grand Shogun and unlocking the powerful Shogun Mode. Jayden then has the Bullzord's Megazord form, Bull Megazord, face off against Crustor's Mega Monster form and uses the power of Shogun Mode to successfully bring this battle to a close.

Mia's younger brother Terry Watanabe comes to town and tries to convince Mia to sing in his band as part of his performance at a children's hospital. Mia is reluctant to help Terry as her parents want Terry to get into med school. Meanwhile, Serrator begins his next attack on Earth, which overwhelms the others until Mia shows up, and she drives him away to bring his plan to fruition. At the same time, Bulk and Spike try to form their musical act. Mia and Antonio sing at the concert together.

Kevin loses his Samurizer in an attack by Skarf while near a swimming center where a meet is being held – there, he reunites with one of his old swim team members and begins to think that he should return to swimming as his friend is not as good as he was, and his Samurizer is still missing. Mike calls Kevin's Samurizer to track down Skarf, discovering the Samurizer is in the Nighlok's arm. Elsewhere, Dayu finds a part of Deker's Uramasa as Serrator approaches her – he tells her where she can find Deker to serve under him in exchange for Dayu's harmonium and Deker's Uramasa getting fixed. Dayu and Deker enter the fray with Skarf, so Deker (who is wielding a different sword) may fight Jayden in his Super Samurai mode. However, Dayu and Deker end the fight prematurely by destroying Skarf (since Serrator mentioned that the destruction of Skarf could unlock his secondary power), giving the Rangers the chance to retrieve Kevin's Samurizer. When the Nighlok enlarges, he gains a shield, forcing the Rangers to form the Samurai Gigazord for the first time, with Jayden using Shogun mode to break through the shield and destroy the Nighlok. Later, Kevin goes to the swim meet to see his old friend win after using Kevin's advice.

This episode was featured in the 2013 Colors of Courage Marathon.

Bulk tries training Spike to be a Samurai until the mail arrives and they find out that the rent is overdue. Meanwhile, The rangers battle Duplicator overwhelms the Rangers with his clones until he is forced to retreat. Spike gets fired from all three jobs that he tried, and Mia talks to him, and he reveals to her that he wants to be a samurai, so she tells him never to give up. Back at the Shiba House, the Rangers talk about the Nighlok, and Mia comes back, and she also tells them never to give up. They figure out that the LightZord can help them, which they use to defeat Duplicator when the LightZord finds the shadow of the real Duplicator. After Duplicator comes back as a mega monster, Mia uses the Shogun Disk to access Shogun mode, and she fires the battle cannon to finish him off. Bulk and Spike end up getting a job catching fish for Antonio.

At the Shiba House, Kevin watches as Emily and Mike train. Kevin tells Emily that she needs to be tougher. Mia tells Emily about a sale at the mall where she buys an outfit that makes her look tough. Mia accidentally drops her wallet at the mall, and it is found by Bulk and Spike, who attempt to return it. At the Sanzu River, Serrator tells the Nighlok Grinataur about his mission, to give humans an insatiable urge to eat, eat and eat until they "burst." Grinataur manages to put the Rangers (save Emily) under the eating spell. Ji tries to help the rangers with their uncontrollable hunger and thirst to no avail. Bulk and Spike discover the Shiba House's location from Mia's Driver's license and ask Mentor Ji if they can train there. Mentor Ji puts Emily in charge of training Bulk and Spike to be Samurai, which is harder than they thought. In the end, Emily destroys Grinataur on her own. When the effects disappear, the other Rangers are affected by amnesia, so Emily and Mentor Ji tell them that it was the toughest day ever.

During training, Jayden mentions to Kevin and Mike that they would both be twice as strong if they were to work together. The Gap Sensor then sounds, and the Rangers encounter the Nighlok Epoxar. During the fight, Kevin and Mike get their hands glued together by Epoxar before Antonio shows up and drives him off. After a few attempts to cut the glue off, the Rangers realize that defeating Epoxar is the only way to separate Kevin and Mike. Though the boys attempt to prove that they can fight in light of the literal sticky situation, they are told to stay behind. While Kevin and Mike eventually get along, the others train to deflect Epoxar's glue until the Nighlok returns to glue every person he comes across to something or each other. Following the others, Kevin and Mike watch their teammates fall into Epoxar's trap. With Kevin following Mike, the boys transform, and they manage to slay Epoxar, negating the Nighlok's glue. Bull Zord and Claw Zord arrive to hold back Epoxar with Light Zord's support before they destroy him. Meanwhile, Serrator promises to fix Deker’s sword Uramasa and Dayu’s Harmonium in return for their services, and he provides them with temporary weapons. Back at the Shiba House, Kevin and Mike show everyone what an excellent team they make by sorting the groceries out together until they accidentally end up dropping the eggs.

After learning of possible Nighlok activity on an island called Monalua, the Rangers travel to investigate. Upon arriving, they split up into three groups. Emily and Kevin encounter a young boy who tells them of ash, seemingly coming from a nearby volcano, is causing the villagers to become extremely paranoid. Meanwhile, Master Xandred, Octoroo, and the Nighlok Malden test out their new Master Blaster inventions to be used on the Rangers. After warning the others via their Samuraizers, they attempt to regroup to form a plan but are ambushed by Dayu. Elsewhere, Serrator ambushes Mike and Antonio and taunts them over the fact that they’re still using swords. Deker attacks Jayden and Mia, noting that Jayden has become weaker upon relying on his teammates in battle rather than fighting solo. This distracts him and allows Deker to injure him until Mia takes him out of the battle and into safety. Meanwhile, at the Sanzu River, the Nighlok Maldan demonstrates his newly developed laser blaster weapon to Master Xandred, with Maldan's Mooger Squad using the weapon for target practice. Still enraged by Deker’s words, Jayden runs off to fight Deker, again, with Mia in tow. They arrive at a mountain guarded by Dayu and Deker that is producing the ash infecting the village. Mia fights Dayu as Pink Ranger, as the other Rangers arrive. Just then, Maldan appears with his Mooger Blaster Squad. The Rangers use their speed to get close enough to the Moogers to take them out until Antonio gets gunned down by the Mooger’s reinforcements, who overwhelm the rest of the team. At the last second, Mentor Ji arrives with the Bullzooka (a gift from Cody), and utilizing the Bullzooka, Jayden destroys Maldan and his mooger squad. When Maldan revives, the others hold him off while Jayden destroys the ash source and thus breaking Serrator's hold on the island. Serrator then takes Dayu and Deker away, leaving a Papyrox and a pair of Spitfangs to keep the Rangers at bay. Then the Rangers form Claw Armor Megazord to destroy the spitfangs and eventually needing to use Samurai Gigazord to destroy the Papyrox. Having freed the island, the Rangers head back home.

Jayden has doubts about his ability to be Red Ranger, and he ends up taking his anger out on the team during training. While this occurs, Master Xandred has Octoroo demand Dayu's Harmonium from Serrator. Serrator takes Octoroo to where he hid the instrument and then attacked him, revealing that he has no intention of handing the Harmonium over. His deception of Master Xandred is over. This causes Octoroo to retreat and causes the Gap Sensor to detect his movement. Sensing her Harmonium’s presence, Dayu makes her way to Serrator's location just as the Rangers arrive to fight him and are outmatched. Using the Harmonium as a shield, Serrator overpowers Dayu until an enraged Master Xandred arrives in the human world to annihilate both him and the Rangers, even if he is destroyed in the process from rapid dehydration. Serrator loses the Harmonium and escapes, leaving the Rangers to fight Master Xandred, who effortlessly defeats them all. Jayden in Super Mode then takes on Master Xandred, one on one but is still no match. After repairing Dayu's Harmonium, the nearly dried out Master Xandred is dragged back into the Netherworld by Octoroo, who leaves the Colossal Mooger Cannon Company to finish off the Rangers. Emily watches over an unconscious Jayden, leaving the other Rangers led by Kevin to defeat the Moogers. Kevin uses Shogun Mode to finish the job. As the severely wounded Jayden is taken back to the Shiba House, Master Xandred is dropped into the depths of the Sanzu River to regain his strength, leaving Serrator to take over his ship with no opposition.

Kevin notices that the places that Serrator’s Nighloks attacked prior all form a straight line. On Master Xandred’s Ship, Serrator summons the Nighlok Pestilox to attack at the appropriate locator point. Antonio catches a large fish at the docks and takes photos of it at a nearby photo booth. Back at the Sanzu River, Octoroo confronts Serrator after discovering his 200-year plan. Octoroo learns that Serrator was wedging sadness in a pattern. Serrator is impressed reveals that Deker is an important tool in his plan. In the forest, Dayu informs Deker that she doubts Serrator will keep his word, but Deker merely tells Dayu to stay away from Serrator. Pestilox begins his assault, and Mentor Ji calls Antonio to battle. Pestilox fires insects into the mouths of the citizens, causing them great stomach pain. Bulk and Spike decide to take a break from their training to eat, and they notice the injured citizens and the Nighlok. Pestilox turns his attention to Bulk and Spike. The Nighlok fires the insects towards them, but they hide in the Photo Booth. Suddenly Spike feels the same pain, but it is merely an empty stomach. Bulk and Spike move the photo booth towards the food. Several photos are taking during their journey and lunch. Pestilox enjoys his victory until the Gold Ranger makes his appearance. The Gold Ranger attacks Pestilox while the other Rangers and Moogers join the fight. Pestilox fires the insects towards them. Green Ranger blocks the attack with the Forest Spear. Red Ranger fires the 5-Disc Cannon, but Serrator blocks the attack. Super Samurai Red Ranger and Rangers Pink and Yellow work together against Pestilox while the others fight Serrator. Deker arrives at the scene with his Temporary Sword aimed at Serrator's back. Serrator tells Deker how the recent Nighlok fights have created the opening for his ultimate plan: To flood the entire Sanzu River into the human world and thereby allow him to become the ruler of both worlds. Super Samurai Red Ranger fires the Super Bullzooka and defeats Pestilox, who grows to his Mega Mode form. The Rangers form the Samurai Megazord to face off against Pestilox. Serrator details how Deker's role as a half-human, half Nighlok is important to the mission. Pestilox is defeated when the Rangers form the Claw Armor Megazord and Jayden powers up to Shogun Mode. Dayu overhears the conversation with Deker and Serrator. Deker, who wants Uramasa back, is uninterested in Serrator’s plan, but Serrator tells Deker that his curse will be lifted by fulfilling the sword's true purpose. Serrator's plan starts as energy blasts emit from the ground at the wedge points. Serrator floats in the air and admires his near victory. Deker falls to the ground. Jayden tries to stand up but is too weak to do so.

In the city, the Rangers slowly awaken from the recent attack. Antonio stands up to find the Barracuda Blade and the injured Deker. Antonio prepares to finish off Deker to prevent him from taking part in Serrator's plan. He controls the urge and leaves the scene. At the Shiba House, as the Rangers discuss the recent events to formulate a plan, Antonio apologizes for not taking the opportunity to defeat Deker, despite his friends telling him that he was noble for not attacking Deker when he was unable to defend himself. In the forest, Dayu follows Deker, who remembers Serrator's words as he stumbles upon their old home's remains. The Gap Sensor sounds, and Jayden orders the Rangers to split up to find Antonio and deal with the Gap issue. Serrator enjoys his recent victory and awaits Deker to take his place. Deker walks down the road until he runs into Antonio, who tries to reason with him, but Deker attacks him. Mike and Kevin arrive in time to protect Antonio. Chasing after Deker as he regains Uramasa from Serrator, the regrouped Rangers cannot stop him with Serrator in their way. But at the last second, Deker strikes down Serrator instead of the final marker. Deker reveals that he only cares for the sword, not the hatred for humans, and tells the Rangers to finish off Serrator. The Rangers morph into action and destroy Serrator with the 5 Disc Octo Cannon and Super Bullzooka. Serrator grows to his Mega Mode and battles the Bull Megazord and LightZord while the Samurai Megazord and Claw Battlezord destroy the Papyrax Serrator summoned. The Rangers form the Samurai Gigazord to finish off Serrator, only for the Symbol Powered Shogun Strike not to affect him. On Gold Ranger’s suggestion, Shogun Red summons the Shark Zord and combines it with Gigazord into a true final combination called Samurai Shark Gigazord to finally destroy Serrator the Shark Sword Slash. In the forest, Dayu confronts Deker about his decision. Deker responds that he will end his curse on his terms. As the sun sets, the Rangers celebrate their victory.

Bulk and Spike attempt to block one of the energy beams in the ground with a giant ball of chewing gum in a subplot.

Mia watches as Jayden trains alone. She notices a monk delivering a message with the Shiba Crest. Mentor Ji gives the message to Jayden, who carefully reads the document. Jayden is worried that his friends will finally learn his secret. Meanwhile, on Master Xandred’s Ship, Octoroo is glad to see Dayu returning as he tells her Xandred is still recovering in the Sanzu River. Octoroo summons the Nighlok Fiera to ambush the Red Ranger. He gives her an artifact filled with evil flames from the Sanzu River and was designed to take down the Shiba clan leader. When she attacks, Jayden is protected by the others against his wishes. The pain from Fiera’s attacks begins to take its toll on Jayden. With the other Rangers down, Jayden uses the Black Box to finish the fight, barely surviving as he destroys Fiera with the Super Bullzooka. Dayu wonders why the fire didn't consume the Shiba Clan head, while Octoroo has an idea on why it didn't work. Fiera grows to Mega Mode, and Jayden gives Kevin the Black Box.

Lauren was sent into hiding to master the Sealing Symbol while Jayden was chosen to take her place temporarily. Lauren has now mastered the sealing symbol. Lauren takes care of Jayden’s injuries, but he plans to leave the team, as he believes the Sealing Power is their only hope to defeat Master Xandred and that there can only be one Red Ranger.

Master Xandred is upset about Halloween. Octoroo has a plan that involves Trickster, a Nighlok that traps the Rangers in bad dreams. In a forest, the Moogers attack people in animal costumes. Trickster watches the scenes from a movie theatre laughing. The Rangers (also dressed in animal costumes) arrive at the scene. After a brief roll call, the Rangers fight the Moogers. After the battle, Blue Ranger enjoys his best costume, but then the Rangers ponder how they got to the forest. The Rangers are then teleported to a concert where Mia sings, and the Rangers are her background dancers. After this, Trickster prepares for their next dream. The Rangers are de-morphed and teleported in a quarry where they fight against Moogers. After briefly pausing and rewinding the events, Trickster enters the scene and challenges the Rangers. After a lengthy morph sequence (which Trickster points out), the Rangers take on Trickster and the Moogers. The Rangers combine the Octo Disc with the 5-Disc Cannon to form the Multi-Disc Cannon to defeat Trickster, who grows into his Mega mode. The Rangers summon their Zords and form the Octo Spear Megazord. Trickster grows to an even larger form. The Giant Trickster taunts the Megazord. Red Ranger recognizes the hypnotic sound from their past scenes. The Megazord destroys the source of Trickster’s illusions: A rotating fan. Back into reality, the Rangers power up their Spin Swords and attack Trickster one by one. Trickster grows to his Mega mode again. Red Ranger powers up to Super Samurai mode and summons the Claw Armor Megazord. The Rangers summon the Symbol Power Shield and trap Trickster into his illusion. Trickster, who is unaware, watches the scene from the movie theatre laughing. The Claw Armor Megazord fires a blast through the movie screen, which destroys Trickster, much to his surprise. The Samurai Rangers then enjoy their victory.

After battling a Nighlok named Gred, the Rangers find themselves stranded inside a malfunctioning Megazord. They overcome this situation with the help of the Christmas spirit, determination, and teamwork.
