Radical

Few characters can claim a debut in one of the most sought-after corners of the Mirage Comics universe, but Radical does exactly that — stepping onto the page in the 1988 second printing of Teenage Mutant Ninja Turtles #3, a Copper Age artifact born from the creative partnership of Kevin Eastman and Peter Laird. With only a handful of catalog appearances across a run that stretched into the early '90s, Radical is a rare, intimate presence in the gritty black-and-white world where Leonardo, Raphael, Donatello, Splinter, and the enigmatic Raven Shadowheart also roam. That scarcity is precisely the point — for collectors digging into the deeper corners of Mirage's original TMNT mythology, encountering Radical feels like finding a hidden panel in a book you thought you knew by heart.
