Glue B.O.S.S. is a recurring threat in the Gluniverse. He is a large mechanical AI that loves to test Glue Creatures to gather information on them. He has three distinct forms. In all three main forms, he appears to be a massive machine that is composed of clay for the face, a thin sheet of metal, and a wireframe endoskeleton housing all mechanical parts.
He and Steve are the main threats of the Gluniverse, although Steve is more of a main antagonist and Glue B.O.S.S. prefers working in secret.
