Klunk

Klunk is Michelangelo's pet cat, a small stray the easy-going Turtle adopts and cares for, first appearing in the original Mirage one-shot. The affectionate cat serves as a gentle, humanizing companion for the most carefree of the four ninja brothers.

Debuting in the pages of Mirage's Michaelangelo, Teenage Mutant Ninja Turtle #1 back in 1985 — right at the heart of the indie comics explosion that made the Turtles a phenomenon — Klunk is a small but genuine piece of TMNT history, brought to life by the legendary duo of Kevin Eastman and Peter Laird themselves. This Bronze Age character shares the page with Michelangelo, Leonardo, Donatello, Raphael, and April O'Neil across a handful of Mirage's beloved black-and-white titles, making every appearance a collector's delight. Six catalog appearances may sound modest, but in the tight, character-rich world of early Mirage storytelling, that kind of intimate presence carries real charm — a quiet thread woven into the fabric of one of comics' most beloved independent universes.
