Homer defeats numerous opponents and makes it to the finals, despite being injured from the battles with the other robots. In the final match against Professor Frink's undefeated super-robot, an ED-209 look-a-like, Bart finds Homer in the bot after the grueling first round. Caught, Homer apologizes to Bart, but Bart is impressed because of all the pain Homer went through to win his son's admiration. In the second round, ED-209 squeezes Homer out of the robot, but immediately stops as soon as it sees him. Frink explains that the robot follows Isaac Asimov's "Three Laws of Robotics" and "is programmed never to harm humans, only to serve them". ED-209 sets out a comfy seat for Homer and pours him a martini. Homer wins and Bart is proud of his dad.
