Eustace DeMonic before and after his gruesome transformation.
Eustace DeMonic is an angry businessman and CEO of Scumlabs. He has grey hair on the back of his head and is seen with a cigar in his mouth. He appears at the end of a level when a Fryborg, Beezleborg, or V.E.R.N appeared. The cast screen and game manual for Rampage: World Tour states that he has "underworld" connections. This description and his name suggest that his background is demonic in nature.
History[]
For most of Rampage: World Tour, he is seen glaring at the player after a Scumlabs location has been destroyed. Around the end, the monsters go to several special stages to fight him, after becoming a giant bouncing monster via the same toxic waste or perhaps demonic powers. Upon death he leaves a gruesome carcass, although killing him is not mandatory.

Trivia[]
- Eustace's surname, "DeMonic", is a pun on the word "Demonic", which implies something is associated with infernal beings. This could simply be making fun of the fact that he serves as one of the game's antagonists. However, one popular fan theory is that it may be indicative of him having ties to Hell or some other unspecified demonic realm. If that is the case, it may mean that his transformation is due to Devil Worship or perhaps that it is his true Demonic form.
