Willem Viceroy

Willem Viceroy III is Hannibal McFist's mad scientist. He is the evil scientist but rather refined madman responsible for all of the bizarre robots attacking Randy. As McFist’s chief mad scientist, Viceroy doesn’t really care about money or power; he just wants everyone to appreciate his genius.He is voiced by Kevin Michael Richardson.

Personality
Very dry humored and sarcastic, as well as refined and some what effeminate. In the the episode "Monster Dump" he has a pet ameba named "Nicholas". He went down into the volcano to get him, showing that he cares very much about his pet. When falling into the volcano he activated an inflatable lab coat which he was wearing on his regular one, saving him from injury. When Randy rescued Nicholas, Viceroy promised to take a vacation from helping McFist destroy the Norrisville Ninja. He was seen at the end of the episode in Provence, riding his scooter with Nicholas.
