Krang

Krang is a ruthless alien warlord and disembodied brain who allied with Shredder to conquer Earth, operating from the Technodrome. A villain from Dimension X, he appeared in Archie's TMNT Adventures comic series adapted from the animated television series.

Few villains in the Archie Comics universe made quite the entrance Krang did — debuting in 1988 at the height of the Copper Age's most beloved reptilian franchise, this menacing presence stepped onto the page in Teenage Mutant Ninja Turtles Adventures #1 courtesy of creators Michael Dooney and David Wise. Throughout the series' run into the early '90s, Krang carved out a recurring role as a genuine thorn in the side of Raphael, Leonardo, Donatello, and Michelangelo, while also crossing paths with the notorious Shredder across titles like Mighty Mutanimals and Return of the Shredder. With 23 catalogued appearances spread across some of the era's most energetic all-ages comics, Krang is a fixture of that wonderfully chaotic Archie TMNT world that collectors still seek out with real affection. If you're diving into the turtle-powered corner of Copper Age comics, this is a name you'll keep running into.
