Mr. Swackhammer is the main antagonist of the 1996 Warner Bros. hybrid film Space Jam.
He is the evil alien owner of the intergalactic amusement park by the name of Moron Mountain, who seeks to enslave and bring the Looney Tunes cast to his park in order to attract more customers. He is also the boss of the Monstars and the archenemy of Michael Jordan.
Mr. Swackhammer is the evil alien owner of Moron Mountain who realizes that no one is returning to Moron Mountain and that his business is failing. He decides to send the Nerdlucks to capture the Looney Tunes in order to perform their comedic acts in his amusement park, hoping that it could bring back customers as his newest attractions and save his business from foreclosure. This results in a basketball game and Mr. Swackhammer later comes to the planet Earth to watch the Monstars and the Looney Tunes play basketball as the Monstars coach.
Michael Jordan makes a deal with him that if the Monstars win, Mr. Swackhammer would spare the Looney Tunes in exchange for his own freedom as his newest attraction in Moron Mountain. He readily accepts it, so he thinks of the conceivable possibilities of Jordan as his newest attraction, playing basketball with his customers while chained up meaning he would always lose no matter what he did.
However, the Monstars lost to the Looney Tunes, resulting in Mr. Swackhammer being furious and berating the Monstars for failing. The Monstars told Michael Jordan that they were afraid of Mr. Swackhammer because he was bigger than them, but when they realize their current forms are far bigger and more powerful than he is, the Monstars turn on Mr. Swackhammer and strap him to a rocket sending him straight to the moon and possibly back to Moron Mountain. It can be assumed that, as he has failed in finding new attractions, Moron Mountain will go out of business and Mr. Swackhammer will be left penniless and broke.
Mr. Swackhammer is known for being extremely ill-tempered, cantankerous, cynical and overall wicked in nature. He is a stingy and manipulative businessman who seeks to enslave the Looney Tunes as his new workers of Moron Mountain. He is very vituperative, opprobrious, abrasive and nasty towards the Nerdlucks. One of his most contemptible and outrageous plans is trying to enslave the Looney Tunes so he can use them as his new attractions at his theme park in the hopes of saving his business.
Mr. Swackhammer is a short, portly green anthropomorphic alien dog with greenish-blue spots, purple lips, yellow eyes with lavender irises, pointy ears, a pink shirt, blue sandals, a magenta suit with purple interior, and a red rose on his suit.

Despite being the main antagonist, the Nerdlucks/Monstars appeared more than Swackhammer did even though Swackhammer is the Nerdlucks/Monstars' boss.
He is the first character in a live action to be voiced by Danny DeVito.
Ernie Sabella, Joe Pesci, Paul Giamatti, Nathan Lane, John Malkovich, John Goodman, Gilbert Gottfried and the late Rodney Dangerfield were all considered to voice Mr. Swackhammer before Danny DeVito was cast.
Swackhammer was originally going to be a live-action villain, but was changed to a cartoon villain during the end of production.
