Cascan

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

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

Powers/Abilities
Similar to Orishans, Cascans can shoot pressurized jets of water as means of attack. They can also generate blades or whips using their water.

Cascans can survive underwater and swim at high speeds with amazing agility.

Cascans possess enhanced durability due to their biomechanical armor, and are capable of withstanding strong water pressure.

Due to the alterations Kevin Levin has made to the Antitrix, Undertow is more powerful than ordinary Cascans. He also possesses a form of terrakinesis that can cause the ground beneath his opponent to turn into mud.

Omni-Enhanced Cascans can shoot out large amounts of water from the large cannons on their backs. These cannons also allow them to create walls of ice, channel electricity through the water they fire, and release strong gusts of air.

Weaknesses
If a Cascan shoots water at an electric device, they will shocked by the electrified water.

Omni-Enhanced Cascans are vulnerable to being lifted and manhandled by a species with as much strength as an Appoplexian.

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".

According to Duncan Rouleau, the Prime Timeline Ben Tennyson has Overflow available in his Omnitrix.
