Raging Bender

After accidentally beating up the Masked Unit, Bender becomes the new favourite at Ultimate Robot Fighting League.

Act I: "Just walk around not wearing a helmet"
Hermes returns from his vacation and seems to have acquired a unique souvenir: a Brain Slug. As the rest of the crew wants to evade any possibility of assimilation, they all go to the movies. After some discussion, they decide to see All My Circuits: The Movie. Bender is angry about another robot with an exceptionally high head sitting in front of him and teases him continuously, until the stranger's patience is exhausted. He changes into a fighting monstrosity and chases Bender across the theatre, but when he has him cornered he slips on Bender's dropped popcorn (with extra motor oil) and is knocked out. It turns out the stranger was The Masked Unit, a member of the Ultimate Robot Fighting League. As it happens, the Commissioner of the URFL is present and enrols Bender on the spot to fight in the League.

Act II: "Bender the Offender"
Bender is very proud of being a member of the league, until he learns that Ultimate Robot Fighting is the most brutal form of competition in the galaxy. He wants to chicken out, but Leela stops him from doing it and tells a story about her youth in the orphanarium. When she was training Arcturan Kung Fu, she had a sexist trainer, Master Fnog, who deemed her inappropriate for championship because she was female, because women lacked the "Will of the Warrior". She wants Bender to seize his chance to be a champion and takes on the task of training him up for the big fight. At his first big night, Bender wins the fight after a bad start and against his expectations, and is told afterwards that all the fights are rigged and the most popular robot wins. As Bender is not only popular, but lowest-common-denominator, a great career starts. As Bender the Offender, he easily knocks out every fighter of the league, and as he knows the secret of success, he neglects his training, to the dismay of Leela. As his popularity drops, however, the league changes his persona to The Gender Bender and orders him to lose next week's title match. As his opponent is the robotic armoured tank Destructor, Bender reluctantly agrees, but he begs Leela to help him win this fight. At first, she refuses because Bender didn't want her help earlier, but as she learns that Destructor's trainer is none other than her tormentor Fnog, she is eager to train Bender and teach him to fight like a girl.

Act III: "It's Bendering Time!"
The great title match takes place at Madison Cube Garden, with commentaries by Rich Little and George Foreman. Fnog is making his little jokes, making Leela even more determined to beat him somehow. The fight does not go well, as Destructor is punching Bender at will and without remorse. Leela finally gives in and calls for Fnog to call his pupil off, then notices that Fnog has disappeared and a little antenna has taken his place. She locates Fnog under the ring, wearing a cybersuit that makes Destructor mimic his exact movements. She is enraged, especially as he teases her again, and attacks him. However, Fnog manages to take the offensive and is just about to deliver the final blow. Leela blocks that punch and manages to divert his fist to the ground, and accordingly, Destructor does the same. The fist goes through the floor of the ring and knocks Fnog out. As he falls over, so does Destructor, flattening Bender in the process - Bender has lost the fight. But Leela is still proud of him, as she got to beat up someone who hurt her feelings in high school.
