Fiz

Fiz is a Skrull who became entangled with Earth's mutant community, ultimately crossing paths with the X-Men and other mutant factions. His shifting allegiances — spanning the Skrull empire, the X-Men, Generation X, and even the Brotherhood of Evil Mutants — mark him as a figure caught between worlds.

Fiz is a fascinating corner-case in the Marvel Universe — a character with roots in the Skrull empire who somehow found their way into the orbit of mutantkind's most iconic circles. Debuting in X-Men #96 in 2000, this Modern Age creation by Glenn Herdling and Gregg Schigiel carries a genuinely unusual set of allegiances, with team affiliations spanning the Skrulls, the X-Men, the Brotherhood of Evil Mutants, and Generation X — a range that hints at a complicated, shifting loyalties kind of story. Fiz shares pages with heavy-hitters like Professor X, Rogue, and Bobby Drake across Uncanny X-Men, X-Men, and X-Men Unlimited, which is elite company for any character. With only eight catalog appearances, Fiz is a true deep-cut discovery — the kind of find that reminds you just how much Marvel's mutant corner of the early 2000s was quietly bursting with intriguing, underexplored figures.
