McFist is an easily displeased man, to say the least. While he poses as a nice guy in front of the masses, he is really an antagonistic businessman who is slightly on the dim side. McFist is easily angered, bad-tempered, and prone to violent outbursts; however, he is also quite dim at his job, although he does seem to be getting better as time goes on. He also will often claim any successful idea as his own, despite his seeming lack of intelligence, several of his schemes have come close to succeeding. He's also reasonably capable of creating a friendly facade for the masses, although he does slip on occasion. Despite being an evil man, McFist does truly love his wife Marci McFist and is even willing to put up with his aggressive and boisterous son Bash Johnson for her.
Role in the series
Hannibal McFist, the series' secondary antagonist and the owner CEO and Owner of McFist Industries (which manufactures a wide variety of products), is described as a "Global Gazillionaire" and is the most "beloved man" appearing a wealthy philanthropist. However, McFist is secretly obsessed with gaining more power, and along with his mad scientist Viceroy, he continually plots to kill the Ninja, through a variety of robots and traps. But the world is not enough for McFist. The one thing he wants more than anything is a superpower. So he made a deal: if McFist helps the Sorcerer break out of his hole of a prison, the Sorcerer will reward McFist with the superhuman ability of his choosing.
In the episode "McOne Armed and Dangerous", Randy managed to unmask McFist for the villain he was; however, this led him to be overcome with sadness at having lost everything. And thus he became vulnerable to the Sorcerer's evil magic, turning McFist into a monster. Enraged, he attacked Randy to get revenge. Realizing that provoking his enemy was a mistake, Randy managed to turn McFist back to normal and covered up his evil acts by claiming he had always been possessed with the evil.
