Invader Grapa is an Irken Invader; it is unknown what enemy planet he was assigned to originally, if he was assigned a planet at all. Grapa was seen among the Planetary Conversion Team at Planet Blorch, and was randomly chosen by Almighty Tallest Purple to replace Invader Skoodge, after he and Almighty Tallest Red launched Skoodge into space for being too ugly and short.
