Mimicry is the 9th alien Len 10 changed to. He is a Copatite from planet, Mroncat. He, was found in the deep recesses of Ben 10,000,000's Omnitrix. There is no information on his species. He has the power to copy any alien he wants to. Normally, he has white skin and round balls for hands. He also has no mouth and relies on telepathy to get his point across. Since Len barely knows how to use his telepathy, he rarely communicates with anyone while in this form.
