Ben 10: Alien Legends
Overflow is known as a Hydronian from the water planet Tsunamios. Most Hydronians are free flowing on their planet, but some have a mask that holds them together when traveling on land, which is rare for their species. Overflow's mask has a rounded 'T' design with two green eyes on the horizontal bar. The Omnitrix is located on the forehead of Overflow's mask. His weaknesses include, extreme heat and cold temperatures. And when evaporated, he is basically useless.
