Crazy Mario Fan

The Crazy Mario Fan (real name: Charles Seiberts) is the main antagonist of Super Stuff Bros. Throughout the series, he possesses the body of Unstable Steve. In the majority of the series, he does not appear in physical form. He frequently terrorizes the characters and kidnaps them on multiple occasions. He is psychotic and malevolent as he hired multiple people to attack the brothers. He is portrayed by Evan Jenkins.

* the reason Steve looks like Charles so much is that Charles' spirit takes form in Unstable Steve's body with Charles' former physical traits carrying over.

History
Charles Seiberts was born on September 13th 1970 in Long Island, NY. He was a popular kid all throughout elementary, middle and high school. On his 15th birthday, he got the NES game Super Mario Bros. He started growing an addiction to the game, that drove him mad.

He had started kidnapping people believing them to be Nintendo characters. Eventually he became a wanted man. He fled to Northern Canada, where he attacked police (big mistake), he was then shot and fell back into a large snowbank where he was frozen.

His spirit had fled to a pocket dimension (where time flows extremely slow). He remained there for millions of years (ie. relativistic speed). He had found a new body- Unstable Steve. Since Steve was unstable, it was easier to manifest in his body. Doctors had thought he had a mild case of schizophrenia.

At times Charles Seiberts had full control over him, kidnapping the Mario brothers on multiple occasions. When Unstable Steve had signed up to be on the public access show "CJ's Tips", Charles Seiberts had finally absorbed Unstable Steve's spirit and attempted to kill CJ.

CJ had eventually shot him and Unstable Steve had died. Crazy Mario Fan's spirit had then fled elsewhere.
