Overflow is the Omnitrix's DNA sample of a Cascan from the planet Cascareau in the Andromeda Galaxy.


Overflow is a red metallic alien. He has two containers filled with water on his head and has black mask-like markings around his green eyes. He has two tubes of water reaching from a respirator where his mouth should be to his back, and his forearms are filled with water. He has black three-fingered hands and two black toes on each foot.

Overflow wears the Omnitrix symbol on his chest.

Powers and Abilities


Overflow has an armored exoskeleton which protects his body from damage. He also has enhanced strength.

Overflow can launch pressurized water blasts from the tanks on his forearms. Overflow can use these to propel himself by spraying water downwards. He can also create water blades.

Overflow is able to breathe underwater, as well as swim at high speeds with amazing agility. He has great endurance and can withstand strong water pressure.


If Overflow shoots water at an electric device, he can be shocked while shooting, since water conducts electricity.
