Starface

Starface is the main antagonist of Code Name: S.T.E.A.M. and acts as the leader of the alien forces that invade Earth. This monstrous creature is responsible for reviving the Great Shugguth, attempting to use its power to completely freeze the planet.

Description
As its name implies, Starface has a large mouth made up of five appendages lined with teeth, which can open up into the shape of a star. Each appendage is tipped with an eye stalk that allows the creature to see when its mouth is closed. It has an armored upper body and snake-like lower body surrounded by numerous tentacles, as well as two bladed wings and a separate appendage that it uses to attack with. The back of Starface is composed of a membrane that, when removed, reveals the beast's weak point.
