Chett Englebrick is the main antagonist of The Simpsons 2009 episode "The Great Wife Hope". He is the founder and president of the Mixed Martial Arts Ultimate Punch, Kick and Choke Championship. He is also a martial artist and fights against anyone except a man of the same size as him.
He is voiced by Hank Azaria.
In The Great Wife Hope, when Marge wanted to stop the violent championship in Springfield, she entered the septagon before the match and refused to leave it until the arena is torn down. Chett agreed to do it, but only under one condition: Marge had to beat him in the septagon.
Chett puts posters around Springfield to confirm her defeat, which frightens the family. He continues in tormenting Marge by telling her that she can't win and should surrender when she still can, but she still refuses.
At the match, Chett tricks Marge into letting her guard down by telling her that he didn't want to hurt her, but he hit her so hard that she couldn't stand up. Bart entered the septagon to protect Marge, but Chett caught him and was about to hit him too. This gave Marge courage and she beat Chett. When he told her to turn her back and take a bow, he tried to attack her from behind, but failed, because Marge expected it.
