Professor Vitellary is the yellow member of the DSS Souleye and a protagonist of VVVVVV. He is found in
Space Station 2 (Frown Upside Down). If rescued third, he talks about science and the source of the interference in Intermission 1. If rescued fourth, he wonders what the Gravitron was in Int. 2 (aka The Gravitron).
- Vitellary breaks the fourth wall in Now Stay Close To Me, Intermission 1. He asks what that "giant glowy C is". Vitellary chooses not to specify.
- He may give you a trinket. If he does, Victoria won't give you one.
- "Vitellary" means "egg yolk", which matches his yellow color.
