Gark is a character from He-Man and the Masters of the Universe.
Gark is the pet of Montork, who was summoned to Eternia along with him by the evil wizard Tauron. Tauron used his magic amulet to control Gark's mind, then sent him to do the same to his master. Once Gark and Montork were under his mind control spell, they turned into butterflies to infiltrate Castle Grayskull and were able to overpower the Sorceress, but He-Man stopped them from breaking into the castle's inner chambers. Gark broke free of Tauron's spell just as Montork ordered him to attack He-Man, and licked his face instead.
