MarioFan7070, or MarioFan5050, is a to-be video producer and Super Mario 64 machinimist.
MarioFan's clothes are predominantly colored red and blue. He wears red overalls and gloves, and blue shoes, caps and shirts.
MarioFan is, in his own words, "the 'psychopath' of the gang, pretty much the crazy one". He acts extremely insane most of the time, spewing out incoherent sentences at random. While MF is on friendly terms with many, there are some people that he despises and will madden ad infinitum. MarioFan has brief moments of outright genius, but he is completely oblivious to these instants and immediately reverts to his ludicrous character.
