Michael Myers is a homicidal maniac that stars in the Halloween series and is from the AVGN episode Halloween, in which he is portrayed by Mike Matei. In the episode, Myers tries to kill the Nerd while he babysits two boys. He gets slapped by a bag of the Nerd's shit and has two Atari controller joysticks jabbed into the eye-holes of his mask. He gets his hands on Halloween for the Atari 2600, which seems to weaken him enough for the two boys to beat him up.
He is presumably still at large, as he disappears from the house without much of a trace, and into the night.
