Biografía
In "What is Life?," one of Gunter's known duties is being a stand for the Ice King's video game machine. Gunter also tries to warn the Ice King that Finn and Neptr are in the room. Gunter is mentioned in "What Have You Done?" when Ice King says, "Gunter, dispose of Finn's carcass." Gunter appears again in "It Came from the Nightosphere," where his/her soul is almost stolen and is dubbed "by far, the most evil thing I've encountered" by Hunson Abadeer, and thrown at the Ice King. The Ice King's response is "Gunter, who told you you could fly?" Gunter appears in "The Chamber of Frozen Blades" and is very sick, but it later turns out that she was pregnant. A floating pink kitten hatches from the egg. Gunter re-appears in the episode "Still," trying to mess with the potions Ice King brought to freeze Finn and Jake. Ice King says that Gunter likes to break bottles, which Gunter eventually does. He/She is shown to be a troublemaker in this episode. Gunter's name is written on Marceline's journal in "Marceline's Closet." Gunter appears multiple times in "Holly Jolly Secrets Part I" and "Holly Jolly Secrets Part II." Notably, during his/her "Penguin Dance Party" video, Ice King calls two different penguins "Gunter" in the same scene. It is unknown whether this was intentional by the show's staff. In "Five Short Graybles," Ice King makes Gunter float out to sea on an iceberg because he believes that Gunter is making his castle smell bad. It is also shown that Gunter can play the keyboard, though not very well.
