Cascan

Cascans are a sapient species from the planet Cascareau, in the Andromeda Galaxy.

Appearance
Cascans are aquatic creatures enclosed in red, orange, or gold biomechanical suits of armor decorated with tubes and containers filled with water.

Abilities
Much like the Orishans, Cascans can shoot pressurized jets of water as means of attack.

Cascans can survive underwater and possess enhanced durability, courtesy of their biomechanical armor.

Omnitrix Transformation
The Omnitrix's Cascan representative is named Overflow, who first appeared in the reboot episode "Waterfilter".

The reboot version of Kevin 11 has a mutant hybrid equivalent of Overflow named Undertow, who first appeared in the episode "King of the Castle".
