Minion finds a seemingly harmless button that had also not had been sold. Not knowing what the button does, Megamind pushes the button, and it reveals a giant robot called the MegaMegamind, which Megamind put his evil self in. The robot thinks that Megamind is Metro Man, and starts attacking him. Megamind fights the robot with his new powers, but is defeated. He and Minion hide in the Invisible Car. Megamind decides that they should live in the car from then on, because he programmed the robot to not stop until the hero and his assistant is destroyed. Minion reveals that he still kept the Spiderbot, a robot that Megamind wanted to throw away, suggesting that Megamind should try to be a hero his way rather than try to do the job the way Metro Man did it. Megamind plans to lure the MegaMegamind to a spot where the Death Ray shoots the old observatory in which the real Metro Man was lured to in the original movie. However, Minion realizes that he cannot activate the Death Ray because the control buttons were broken. He then tries to find the Death Ray remote control, but Megamind does not remember what the remote looks like, so Minion tries all the remotes. Megamind, trying to hide, eventually is found by the MegaMegamind because Minion accidentally played rock music on the Spiderbot. Minion finally finds the correct remote and activates the Death Ray. Megamind and the Spiderbot get off the robot, using the robots wristmounted shooter just before the robot explodes.The duo then recover the DeGun from Damien, who not only has refused to rehydrate his mother but also used it on the parents of several other children, who are all now having a party to celebrate no longer having to do as they are told.
