Generations is a limited ten-issue anthology comic book series published by Marvel Comics that ran from August to September 2017. Each issue, written and drawn by different creative teams, features a different team-up of a classic Marvel superhero with their Modern Age counterpart. The series, first teased in February 2017 with artwork by Alex Ross, immediately follows the events of the "Secret Empire" storyline which concludes with a number of modern heroes being sent through time on a journey of self-discovery. According to Marvel Editor-in-Chief Axel Alonso the goal of the series was to examine who these heroes are and suggest where they might be heading in the future.

Despite receiving generally favorable reviews from critics, Generations reported underwhelming sales figures over its two-month course. The events of the series built the foundation of Marvel's company-wide "Legacy" relaunch of comic books, which saw the return of several classic superheroes in more prominent positions.

In February 2017, Marvel Comics released an image teasing the debut of Generations, featuring artwork by Alex Ross which depicted a line-up of classic Marvel superheroes with their Modern Age counterparts. The following month, the first details of the series were revealed via the description of the collected hardcover edition listed on Amazon.com. The announcement of the series came following criticism from a contingent of fans who believed that Marvel's growing diversified cast of characters came at the expense of some its long-standing heroes.

The series is a ten issue anthology, featuring a team-up of different incarnations of ten different superheroes, that ran from August to September 2017. Despite the fact that at the time of publication some of the characters listed in the pairings were either dead or incapacitated, Marvel Editor-in-Chief Axel Alonso insisted that the series is not self-contained and does not take place in an alternate timeline explaining, "These stories do happen, they really count. They really matter. This isn't some alternate reality story... You don't take these characters off the board with the intention to keep them off the board forever. One of the tropes of our medium is characters get a second wind. They die and come back. That's part of the beauty of what we do."

Alonso stated that the ten pairings should "illuminate who they are and indicate where they will be moving in the future." For instance, Brian Michael Bendis writer of the Iron Man and Spider-Man issues said Tony Stark could have a lasting influence on Riri Williams because "[she] is at the most impressionable stage of her life," while Peter Parker and Miles Morales, despite being from different backgrounds, have a "spiritual connection" that allowed him to examine the Spider-Man mantra of "with great power, must come great responsibility" from different perspectives. G. Willow Wilson writer of the Ms. Marvel said Carol Danvers and Kamala Khan have a mentor–student relationship, but "at its heart, Ms. Marvel is about growing up, and a big part of growing up is discovering that your idols have feet of clay – and forgiving them for their flaws as you gain an adult understanding of your own." Tom Taylor writer of Wolverine suggested that Laura's experience with Logan could help her move beyond her violent past.

At the conclusion of the "Secret Empire" storyline, Kobik — the sentient Cosmic Cube — sends a number of heroes on a brief journey of self-discovery through a time portal.

According to the review aggregator website Comic Book Roundup, Generations: The Strongest received an average score of 6.9/10 based on 20 reviews from critics. Jesse Schedeen of IGN gave it an 8.2 out of 10 saying, "Generations isn't shaping up to be a particularly groundbreaking series for Marvel. With little background for the premise of this crossover or its ties to Secret Empire and Marvel Legacy, [Generations: The Strongest] simply plays out as a fun, character-driven team-up between two heroes." David Pepose of Newsarama gave it a 3 out of 10 and said, "[This book] isn't a great first impression for Marvel's latest event. There's something to be said for nostalgia, and giving readers a glimpse at beloved characters who might have been temporarily pushed off the stage, and to that end, Pak makes a solid attempt - but unless you're a diehard Hulk fan, this one-shot will likely prove a disappointment."

Generations: The Phoenix received an average score of 7.8/10 based on 18 reviews from critics on Comic Book Roundup. Blair Marnell of IGN gave it an 8.3 writing, "[Generations: The Phoenix] feels like it should have been an issue or two from the actual Jean Grey ongoing series. Its connections to the overall Generations event are negligible, but it is a very big story for Jean Grey." Justin Partridge of Newsarama gave it a 5 and wrote, "The life of Jean Grey is a complex one, and [Generations: The Phoenix] #1 doesn't do much to make it simpler. But what it does do is attempt to give Jean a bit more control over her tumultuous past and future."

Generations: The Best received an average score of 8.7/10 based on 13 reviews from critics on Comic Book Roundup. Schedeen gave it an 8.1 and said, "It's clear by now that each Generations one-shot is going to follow a very specific formula... But it's one that works well in this Wolverine crossover. This issue makes the most of the Wolverine/X-23 dynamic and celebrates the legacy of a fallen X-Man." Kat Calamia of Newsarama gave it a 9 writing, "[Generations: The Best] #1 keeps the Generations one-shots feeling fresh with a new perspective. If you are a Wolverine fan, this is a must-read issue that delivers an emotional, character-driven story that won't leave a dry eye in the house."

Generations: The Thunder received an average score of 7.9/10 based on 11 reviews from critics on Comic Book Roundup. Schedeen gave it a 5.0 and called it "a weird mashup of different plots, none of them terribly interesting, that isn't saved by its gorgeous pin-up worthy art, or weird story elements stuck at the end." Calamia gave it a 5 writing, "[Generations: The Thunder] #1 lays the ground work for future storylines including Marvel Legacy #1, but misses the heart previous Generations issues delivered on."

Generations: The Archers received an average score of 8.2/10 based on 12 reviews from critics on Comic Book Roundup. Schedeen gave it an 8.0 and said, "It's unclear exactly how much the events of this issue will impact the ongoing Hawkeye series, but it proves there's still plenty of potential left to mine in the Kate/Clint dynamic." Calamia gave it an 8 writing, "[Generations: The Archers] #1 is a fun issue that reestablishes Kate's relationship with her mentor, and reminds us why these two characters work so well together."

Generations: The Iron received an average score of 5.9/10 based on 8 reviews from critics on Comic Book Roundup. Schedeen gave it a 7.2 and said, "I wish there were more consistency as the book shifts from one artist to the next, but Bendis and his artists paint a particularly memorable and hopeful vision of Marvel's future." Calamia gave it a 4 writing, "[Generations: The Iron] has a few nice goodies with the appearances of The Next Avengers and Sorcerer Supreme Tony Stark, but this still isn't enough for the book's $4.99 price tag."

Generations: The Bravest received an average score of 6.7/10 based on 7 reviews from critics on Comic Book Roundup. Marnell gave it a 6.5 and said, "This was one of the Generations one-shots that I had been looking forward to the most, since I'm fans of both versions of Captain Marvel. But Margaret Stohl's story really only delivers one of the title characters."

Generations: The Marvels received an average score of 7.9/10 based on 9 reviews from critics on Comic Book Roundup. Tara Giovannini of IGN gave it an 8.9 and said, "All in all, this was a freaking fun comic in a universe that has seemed of late to be nothing but dour. I can't wait to see how -- or, perhaps it's better to say if -- this comic affects Kamala and Carol's relationship in the future. Even if it doesn't, it was a nice dream. This is the type of comic that reminds you why you love them." Pierce Lydon of Newsarama gave it a 7 writing, "A story like this one, while light and seemingly inconsequential, could definitely affect the relationship that Carol and Kamala have moving forward and this lays the groundwork for some of that. It's something that honors the past while still looking to the future. Wilson, Villanelli, and Herring’s work is the foundation for a new era of Ms. Marvel stories."

Generations: The Spiders received an average score of 7.5/10 based on 7 reviews from critics on Comic Book Roundup. Schedeen gave it a 7.1 and said, "[Generations: The Spiders] ranks among the more disappointing chapters of the series, as it fails to add much to the Peter/Miles dynamic even with the shift in time period. As with Spider-Men II, this story is at its best when Peter is absent from the picture entirely. But for anyone who fell in love with Ramon Perez's art on 'Amazing Spider-Man: Learning to Crawl', this issue is a must-read." Pepose gave it an 8 writing, "The decompression of Bendis's pacing is somewhat apparent - there isn't a ton of story that goes on here, but instead, this book feels more impressionistic, where Bendis uses every inch of page space to create mood rather than plot progression. But thankfully, he's teamed up with an artist who is so talented that he's able to turn this painterly script into a work of art, making [Generations: The Spiders] definitely a book to watch."

Generations: The Americas received an average score of 7.9/10 based on 6 reviews from critics on Comic Book Roundup. Schedeen gave it an 8.5 and said, "[Generations: The Americas] is essential reading for anyone who's been following Nick Spencer's Captain America saga... This issue reads like the proper finale to that long run, offering the closure to Sam Wilson's tenure as Cap that Secret Empire didn't. It doesn't take full advantage of the time travel premise, but it works as well as could be hoped given the limited space available." Partridge gave it a 3 writing, "[Generations: The Americas] won't be for everybody. Hell, it may not be for anybody, but at least now Sam and Steve can dust off their old costumes and see what the future holds for them beyond the Vanishing Points, Secret Empires, and Hydra-Steves of the world."
