Gunter is a penguin that most commonly accompanies the Ice King, despite occasionally attempting to do harm to him. Although Gunter has appeared in many episodes, it is heavily implied that there are many other Gunters, and the name is simply something that the Ice King calls all of his penguins.

During the sixth season, Gunter the penguin is revealed be a primordial space demon named Orgalorg, who desired to absorb the catalyst comet. But Orgalorg ended up in his current state after being defeated by Grob Gob Glob Grod and exiled to early Earth. The planet's gravity condensed Orgalorg into his current powerless and amnesiac penguin-like form as he wandered the planet for ages before he was found by the Ice King.
