Ignus

Ignus is youngest and dumbest of Momon's sons. Because he is the youngest, his horns are the shortest. He is the only one of Momon's sons to be the son of The Great Wizard Grayfarn.

When Cornwood was created, Igner from Universe Γ became Ignus. His role in Cornwood is the same as in Universe Γ, as the least competent of his mother's sons. He is often left behind while his brothers take on the more important jobs, such as Momon's Invasion of Wipe Castle. He found out that he is actually the son of Grayfarn while eavesdropping on his mom. he revealed this to Grayfarn when they fought at the Geysers of Gygax.

When Momon destroyed Cornwood, he became Igner again and helped his father (the Professor) make Dark Matter useless as fuel.

Trivia

 * It is revealed that Farnsworth is Igner's father in Bender's Game during a parody of the fight between Luke Skywalker and Darth Vader, in Star Wars Episode V: The Empire Strikes Back, in Momon's cave.
