Momon is the Cornwood version of Mom. She is similar to the real Mom in many ways, such as being evil and Farnsworth's lover. She also seeks the Anti-backwards Crystal/Die of Power, but wants to keep it, instead of destroy it. She transformed into a dragon and fought with Frydo and took the Die for herself.
- Her name is a parody of Sauron, the Dark Lord of Middle Earth and title character of The Lord of the Rings.
- "Momon" sounds similar to Mammon, a Biblical term used to describe material wealth or greed and sometimes personified as a demon or deity.
