Mister Swackhammer was the evil alien propetier of the amusement park "Moron Mountain" and the main villain in the 1996 live-action/animated film Space Jam. He wanted the Looney Tunes to perform their comedic acts in his amusement park so he sends the Nerdlucks to capture them if they win a basketball game against the Looney Tunes. Swackhammer later comes to Earth to watch the Monstars and the Looney Tunes play basketball. He makes a deal with Michael Jordan that if the Monstars win, Swackhammer would make him into an attraction in Moron Mountain playing basketball with his customers while chained up meaning he would always lose. The Monstars however, lost to the Looney Tunes resulting in Mister Swackhammer being furious with them for losing. The Monstars told Michael Jordan they were afraid of him until they realize they were bigger than they used to be. This means they turn on him and strap him to a rocket, sending him out to the Moon.
He was voiced by the famous actor Danny DeVito.
