Undertow is a cerulean metallic alien. He has two tubes that extend from his head and has black mask-like markings around his red eyes. He has two tubes of swamp green slime reaching from a respirator where his mouth should be to his chest, and his forearms have orange and gray canisters filled with slime. He has black four-fingered hands and three black toes on each foot. He also has a gray protrusion on top of his head with black openings on the front and back that each have three red buttons.
Undertow wears the Antitrix symbol on his chest.
