Teenage Mutant Ninja Turtles: Mutanimals

In 2015, IDW expanded its Teenage Mutant Ninja Turtles universe with Mutanimals, a four-issue miniseries by writer Paul Allor and artist Andy Kuhn. The story spotlights a team of mutated animal allies—including characters like Mondo Gecko, Slash, and Leatherhead—as they carve out their own heroic path in a world that fears them. It’s a gritty, character-driven spin-off that deepens the lore of the TMNT’s corner of the IDW continuity.
