Umbra is a tall, dark blue Mobian aye-aye with large ears, tan skin and pink eyes. She wears a black robe, some jewlery and shiny purple gloves and boots. For unknown reasons, she has a purple gem on her forehead

Umbra is a devious sorceress who wants nothing more than to steal Mighty's Golden Coconut. She will gladly use underhanded tactics to achieve this goal. She is petulant and easily driven to anger and will lash out at those who do not do their job well enough, but when faced with a dire situation, she will side with her enemy.
