Julian Keller

Julian Keller, known as Hellion, is a naturally gifted mutant whose formidable telekinetic abilities earned him a place at the Xavier Institute, where he led the Hellions training squad. Confident and competitive, he quickly distinguished himself as one of the most powerful young mutants at the school.

Born into the Modern Age of Marvel mutantkind, Julian Keller made his debut in New Mutants #9 in 2004, courtesy of the creative team of Nunzio DeFilippis, Christina Weir, and Carlo Barberi — and he's been a fixture of the younger generation of X-Men ever since. Over more than two decades of publishing, Julian has carved out a significant presence across New X-Men, New Mutants, and Wolverine & the X-Men, sharing the page with heavyweights like Wolverine, Scott Summers, and fan-favorite Rockslide — serious company that speaks to his standing in the Marvel mutant world. With 70 catalog appearances and three collector-recognized key issues to his name, he's no background player; this is a character with genuine staying power in the ongoing saga of Marvel's next generation. If you're tracing the evolution of mutant storytelling through the 2000s and beyond, Julian Keller is absolutely worth your attention.
