Shredder

Few villains carry a name as iconic as Shredder, and this particular incarnation stepped onto the page in 1991, courtesy of creators Beth Mitchroney and Ken Mitchroney, in the pages of Teenage Mutant Hero Turtles #3/1991 — a Copper/Modern Age entry published by Atlantic Förlags AB. Running through the early '90s, this version of the character shares his world with some of the most beloved heroes in comics: Donatello, Michelangelo, Leonardo, Raphael, and the wise Splinter. With only four catalog appearances across a short but spirited 1991–1994 run, this is a rare and distinct slice of TMNT history — the kind of curio that makes a collector's shelf genuinely interesting.
