The Joker is a character in two Angry Video Game Nerd episodes, Batman: Part 1 and Batman: Part 2. He is played by Mike Matei.
Batman: Part 1
Nearing the end of the episode, as the Nerd declares that he will no longer play any more bad Batman games, the Joker appears from behind the couch, laughing his trademark maniacal laugh. Believing the Batman-dressed Nerd to be the real Batman, he offers to let the Nerd play his bad Batman game: Batman: Return of the Joker for the NES. Not wanting to play the game, the Nerd punches the Joker and threatens him while grabbing his collar. The Joker, however, activates a liquid spurter hidden in a rose pinned on his suit, blinding the Nerd and causing him to fall over. He then gives the Nerd an electric shock with a joy buzzer hidden in his palm by "offering" the Nerd a hand. Subsequently, he ties the Nerd up on the couch and procedes to force him into playing the Joker's collection of bad Batman games.
Batman: Part 2
Continuing where the first part left off, the Joker is forcing the Nerd to play his collection of bad Batman games, starting with Batman: Return of the Joker, and subsequently continuing with the Batman: Return of the Joker on Game Boy and Batman: Revenge of the Joker on Sega Genesis. Throughout the ordeal, the Joker taunts the Nerd on his dislike for the games, with every cry for silence by the Nerd falling on deaf ears. After being particularly disgusted by Batman: Revenge of the Joker, the Nerd breaks free of his bounds and has a fight with the Joker. Gaining the upper hand, the Nerd knocks the Joker onto the sofa and proceeds to shove the games the Joker made him play up his anus, at which the Joker laughs masochistically.
