Undertow is a gray 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 green slime reaching from a respirator where his mouth should be to his chest, and his forearms are filled have canisters filled with green slime. He has black four-fingered hands and three black toes on each foot.
Much like Overflow, Undertow’s voice has a slightly muffled echo.
Undertow wears the AntiTrix symbol on his chest.
Powers and Abilities
Undertow has the same abilities as a Cascan as well as the ability to cause the ground beneath his opponent to turn into mud. His water seems to be a sort of swamp green slime.
Undertow's genetic modifications make him too powerful for Kevin to properly control.
- Undertow first appeared in King of the Castle, where he battled Four Arms before switching into Dark Matter.
