In the new Ben 10 reboot show Ben Tennyson has unlocked a brand new alien that can swim, blast water, make water weapons, and do other things. This new alien is named Overflow! 

Species and Home PlanetOverflow’s species is called an Cascan and where he comes from is a planet located in the Andromeda Galaxy (the same galaxy where Water Hazard, AmpFibian, Armodrillo, Terraspin, and NRG come from) called Cascareau. See images below:

Overflow's home planet

Description (Ben 10 Reboot)Overflow can be described as a red metallic robotic alien with two containers filled with water on his head. He 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. The Omnitrix symbol is located on his chest. See images below:


Description (When used by Kevin 11): When Kevin used an Anti-Trix mutant version Overflow which he names Undertow, he sort of looks the same Overflow expect that he’s a gray metallic alien, with two tubes that extend from his head and has black mask-like markings around his red eyes. He has two tubes of green slime reaching from a respirator where his mouth should be to his chest, and his forearms are filled have canisters filled with green slime. He has black four-fingered hands and three black toes on each foot. Much like Overflow, Undertow’s voice has a slightly muffled echo. Undertow also wears the Anti-Trix symbol on his chest. See Image below:


Special abilities: Overflow’s first ability is the armored exoskeleton he has which protects his body from any damage. His second ability that he has is enhanced strength. Overflow’s third ability shows that he can be able to launch pressurized water blasts from the tanks located on his forearms. Overflow can use these to propel himself by spraying water downwards. His fourth ability shows that he can also create water blades. Overflow’s fifth ability is like Ben’s other transformations he is able to breathe underwater. His sixth ability also shows that he can swim very well at high speeds with amazing agility and creating whirlpools and shockwaves underwater. His final ability shows that he has great endurance and can withstand strong water pressure which is very impressive. See images below:

WeaknessesOverflow’s first weakness is that if he shoots water at an electric device, he can be shocked while shooting, since water conducts electricity and all. Overflow second weakness is that he can be harmed by magic, as shown when he was incapacitated by one of Hex’s spells. Overflow’s final weakness is that he can accidentally cause a flood in confined spaces if he releases too much water. See images below:
