The Bodybuilder is the main antagonist of "Rigby's Body". He is a pink Bodiless Consciousness who was once human who was bodybuilding too hard. His friend told him that if he kept pumping iron like that his body would quit on him (which it did); he didn't find it in time and had to take the form of a basketball. He is probably in the form of a basketball because in his human form, he was athletic and strong, and a basketball gives is a sports reference. When he made contact with Rigby, he finds and steals his body. They fight later in the episode. Skips drove the golf cart into Rigby's body which sent the Bodybuilder's consciousness crashing onto a slide, taking form of it, then became disgusted that his mouth was open when a fat kids butt slid over him.
- "Aw, man, my mouth was open!"
- "So long, suckers!"
- "Your body's still good?"
