Feral

Maria Callasantos is a feral mutant whose animalistic nature and fierce combat skills led her to the streets and eventually the tunnels of the Morlocks before joining the New Mutants and the newly formed X-Force, where her savage edge made her both an asset and a liability.

Bursting onto the scene in the 1991 Marvel Holiday Special — courtesy of creators Danny Fingeroth and Ron Garney — Feral is a Copper/Modern Age Marvel wildcard whose raw energy and edge made her a fixture of the mutant corner of the Marvel Universe. With ties to both X-Factor and the X-Men, she's carved out a place among some of Marvel's most intense ensemble casts, sharing adventures with heavy hitters like Cannonball, Warpath, and James Proudstar across the pages of X-Force and The Uncanny X-Men. Thirty-plus years of appearances and seven collector-recognized key issues speak to a staying power that goes well beyond a one-issue debut. If you're diving deep into the gritty, high-stakes mutant storytelling of the '90s and beyond, Feral is absolutely a name worth tracking down.
