MarioMario54321 first joined YouTube in 2007, and his first upload was MM54321's SM64 Bloopers: Mario Jumps The Castle!. He soon got involved with making the Doppleganger arc, starting with Super Mario 64 Bloopers: Mario VS Oiram, and continuing with various series of evil doppelgangers of the main protagonist constantly attacking the Mushroom Kingdom. This culminated in his longest series, 2011's OiramOiram12345 and the Dark Star X.
