Orishans are a species of naturally armored aliens from an unknown planet in the Andromeda Galaxy.
Orishans are a red mollusk-like species. They have two large eyes or four splitted eyes. They have small grey spikes and black spots on the back of their legs and shoulders.
Orishans have port holes on their four fingered hands.
An Orishan's hood has a retractable visor.
Only male Orishans have been seen so it's unknown what female Orishans look like.
Powers and AbilitiesOrishans have an armored exoskeleton which protects their body from damage, including radiation.
Orishans can absorb moisture, including from the air, through the port holes in their hands.
Orishans can launch pressurized water blasts from these same holes.
According to Dwayne, Orishans are able to manipulate water and even mold it into a wide variety of shapes.
