|Mortos der Soulstealer|
|First Appearance||Mortos der Soulstealer|
|Voice Actor||Wally Wingert|
Although Dib intended to use Mortos to steal Zim's soul, the plan backfired when a passerby wished for ice cream. Mortos granted his wish, and departed to the spooky realm. The ice cream was discarded upon the revelation that it contained raisins.
Before he became evil, he used to have a friend who sang to him, but broke his heart. Dib also described Mortos as being a mooch, since he had to pay for all of Mortos' "recharging."
He seems to enjoy the feel of tombstones on his face, and wears boxer shorts with hearts on them . He also hates the "Ancient Pamphlet" that binds him to wish-granting. His only friends are the dark energy of the universe and a girl named Darlene.
- Mortos' voice was based on Mike Myers' Lothar of the Hill People from SNL.
