ER Zomboss

As if VR wasn't nerd enough.

Emergency Room?
No, exectution room. You may assume that he would specialize as the taskforce's medic, but no, he's just a psychopathic genius. He's apparently "smarter" than VR, but this is probably just a misconception. He enjoys torturing people, but never has any living enemies to torture, so he often dismembers bodies instead. He despises VR, seeing VR as a threat to his [not] superior intellect.

ER the Ultimate Weapon
ZR has ordered ER to a secret project, a project to transform the body of the deceased [killed during an assault against VR] ER_Zomboss into an ultimate weapon. After his transformation into a mechanical abomination he betrayed ZR destroying his base. His next move was to. eliminate all 2.5 octodecillion fuckin' ugly living scum of the universe. VR calls upon. himself to eliminate ER and use his enhancements to his advantage. After he defeats ER, VR plans to use his body for world conquest, but lost the body after tossing it into a closet.
