Vadaquian

Vadaquians are an aquatic race of aliens from the planet Vadaquas, an ocean planet from the Mosconian Galaxy.

Biology
Members of the species are short with pinkish grey skin, a long neck and dark brown hair cover their head. They wear suits and helmets filled with water which implies members cannot survive on land.

History
A small group of Vadaquians immigrated to Earth after Aku drained their planet of its water. Members of the species habited the ocean but after Aku's death in the past which undid everything he caused to Vadaquas. Therefore, the Vadaquians presumably live at peace thus they would never have came to take refuge on Earth.
