Cascans[1] are a species of armored humanoid creatures residing on the planet Cascareau.


Each specimen is a large humanoid creature with an armored exoskeleton. This exoskeleton has one to three tanks on the head, and two tubes that extend from their respirator to a unit on the back. They have jets on their hands that shoot out water from two extra tanks in the forearms. They have green eyes, three fingers, and two toes.

Their armor is made of Serpent Glass[1] and they are primarily seen to have red exoskeletons. However, orange, blue, green, and gold exoskeletons have also been seen.


The Cascans dwell beneath the waves to avoid the perils of its surface, including torrential hurricanes and pirates. They hunt for the raw material that comprises their exoskeleton armor, Serpent Glass, which is collected from the spires that dot the horizon.

Cascans can create weapons out of their water, such as blades and whips, as demonstrated by Overflow and Undertow respectively.[2][5]

By generating large amounts of waters into other bodies of water, Cascans create tidal waves.[5]
