Jack Finney

Splashing onto the scene in 1989 courtesy of Dean Clarrain, Ryan Brown, and Ken Mitchroney, Jack Finney is a product of the vibrant Copper Age energy that made Archie's Teenage Mutant Ninja Turtles Adventures such a beloved corner of the TMNT universe. Over a run stretching into the mid-nineties, Finney carved out a niche across Mighty Mutanimals and the main Adventures title, sharing wild, imaginative pages with a colorful roster that includes Man Ray, Mondo Gecko, Jagwar, and the Turtles themselves. With 27 appearances spread across three series, he's the kind of character that rewards deep-diving fans who want to explore the full, sprawling world Archie built beyond the cartoon — a genuine piece of that era's adventurous, anything-goes spirit.
