Claremont revolutionized the X-Men like no one else has. He built his team nearly from scratch, introduced loads of new villains, and helped spearhead the maturation of the comic medium. Basically, if you like the X-Men in 2025, you have to him to thank. He’s the team’s most important writer, and honestly the best one as well. However, he’s not the only great writer the team has had. Some of the best writers in comics have graced the team’s books, and these seven are the best who aren’t Claremont.
7) Gail Simone

Gail Simone came onboard Uncanny X-Men in 2024, as part of the “From the Ashes” status quo shake-up. Since then, she’s been killing it with the book. All of “From the Ashes” owes a lot to the team’s past, to the extent that a lot of books are straight rehashes, but Simone has found a way to recapture the flavor of older X-Men comics without completely copying what came before. Her work is very much indebted to Claremont’s style of writing; she understands how to use her stories to build characters and how to use dialogue and caption boxes to give the book it’s own flavor. She’s able to blend amazing character-building with compelling plots and wild action, making Uncanny X-Men a joy to read on a monthly basis. Her work reminds me of the Outback era of Claremont’s X-Men, and it’s fantastic. Uncanny X-Men has escaped the “From the Ashes” curse because of Simone’s deft writing.
6) Jonathan Hickman

The Krakoa Era brought the X-Men back to prominence after years of Marvel sidelining the team, and we have Jonathan Hickman to thank for that. House of X/Powers of X was just the shot in the arm the team needed and it lead to a revitalization of the mutants at Marvel. Hickman’s X-Men wasn’t always the best book, but his work on House of X, Powers of X, and Inferno showed that he had the goods when it came to the team. I would go so far as to say that most of the problems with Hickman’s run on X-Men came not from any problems with his writing but more because so much of what he wanted to do with the team was in flux because of changing behind the scenes realities. Hickman’s time with the group led them to some of the greatest successes they’ve had in years, and it will always be remembered fondly by fans.
5) Fabian Nicieza

Fabian Nicieza had some big shows to step into. Nicieza was one of the writers that Marvel tapped to replace Claremont on the books. At first, Nicieza would help plot and script the books with artists like Rob Liefeld on X-Force before taking over as main writer of Both X-Force and X-Men when the Image exodus took away Liefeld, Jim Lee, and Whilce Potracio. Nicieza wrote X-Men when it was the biggest book in comics, and did a pretty great job all things considered. He had a short run on the book, but helped chart its course through stories like “Fatal Attractions”, “The Phalanx Covenant”, and “The Age of Apocalypse”, and introduced Kwannon to the X-Men. He also played a big role in the early stages of the relationship between Rogue and Gambit, showing that he had a deft grasp on the characters.
