Axo

Axo is a young mutant introduced in Peach Momoko's Ultimate X-Men, set in Marvel's reimagined Ultimate Universe. A new voice among that world's emerging mutant community, Axo has since crossed over into the main Marvel line, appearing across Exceptional X-Men, Uncanny X-Men, and X-Men.

Fresh from the pages of Peach Momoko's visionary Ultimate X-Men in 2024, Axo is one of Marvel's newest mutant voices — a Modern Age creation already making a mark across some of the publisher's most storied titles. In just a short time, Axo has racked up 37 catalog appearances spanning Exceptional X-Men, Uncanny X-Men, and X-Men proper, a remarkable footprint for such a recent debut. That first appearance carries key-issue status, making it one worth hunting down, and the company Axo keeps — sharing adventures with Wolverine, Cyclops, and a compelling cast of newer faces like Alex Luna and Trista Marshall — signals a character woven right into the heart of contemporary mutantkind. Momoko's distinctive artistic sensibility gives Axo's origins a unique flavor, and with the X-Men line firing on all cylinders, this is a character collectors and fans will want to get ahead of.
