Cosmic Owl appears in the episode “Prisoners of Love” in which Finn knocks out the Ice King and the Ice King falls into a deep sleep. The Ice King is then seen flying across the stars and the night sky with Cosmic Owl, and he asks her why people don’t like him. Cosmic Owl answers “You’re a sociopath”. Cosmic Owl is also seen in “Donny” as a drawing who will destroy the Why-Wolves as their population grows, and in “The Real You” in the library as a carving. It is unknown whether Cosmic Owl is good, evil or neutral.
