Skoodge

Invader Skoodge is among the shortest Irken Invaders. He is the closest thing Zim has to a best friend (although it is hard to tell, as Zim often abuses him). Skoodge and Zim went to school together at the Irken Military Training Area underground. Despite his success as an Invader, Skoodge is hated by the Almighty Tallest for being 'so short and ugly', most likely because this success proved that height has no effect on an Invader's competence.
