HOW A NAIVE BOY BECOME MEGAMIND

Supervillain Megamind and his arch-nemesis, the superhero Metro Man, are both aliens who were sent to Earth as infants before their planets were sucked into a black hole. Though both land in Metro City at the same time, Metro Man is raised in a mansion, while Megamind is raised in a prison. He goes to the same school as Metro Man, who is well-liked by his classmates. Megamind is bullied by everyone until he concludes his purpose is to be a supervillain, setting off a rivalry between him and Metro Man. As an adult, Megamind, aided by his fish-like companion Minion, frequently and unsuccessfully battles Metro Man for control of the city.

At the grand opening of the new Metro Man Museum, Megamind escapes prison, kidnaps reporter Roxanne Ritchi, and lures Metro Man to an abandoned observatory to rescue her. Once there, Metro Man collapses, stating the copper-lined observatory roof weakens his powers before Megamind blasts him with a sun-powered death ray and is overjoyed to finally win. Megamind takes over the city and goes on a crime spree. However, he eventually becomes depressed and purposeless with no hero to fight.

Megamind decides to blow up the Metro Man museum to forget the hero, but sees Roxanne there and dehydrates the museum's curator, Bernard, into a small cube. Disguised as Bernard using hologram technology, Megamind talks to Roxanne, whose remarks inspire him to use Metro Man's DNA to create a new superhero to fight. Megamind perfects the formula, but accidentally injects it into Hal Stewart, Roxanne's dimwitted cameraman who is infatuated with her.

Disguising himself via hologram as Hal's "Space Dad", Megamind offers to train Hal to become a superhero. Hal, seeing this as a chance to get with Roxanne, accepts and takes on the name "Titan", though he misspells it as "Tighten". Megamind begins to date Roxanne in the guise of Bernard, and he and Minion have a falling out over Megamind's apparent lack of interest in committing further crimes. Roxanne rejects Tighten when he comes to court her, and Tighten later witnesses her on a date with "Bernard". After a heartbroken Tighten leaves, Megamind's "Bernard" disguise fails, and Roxanne rejects him as well.

Megamind arranges to fight Tighten the next day, but Tighten does not show up. Megamind learns that Tighten is now using his powers on a crime spree. Tighten offers to ally with Megamind, but the latter deliberately reveals his disguises and deceptions, hoping to goad Tighten into fighting. Angered, Tighten savagely beats Megamind in the fight. Realizing that Tighten has no interest in justice and means to kill him, Megamind traps Tighten in a ball of copper. However, Tighten easily breaks out. Megamind and Roxanne escape to Metro Man's old hideout, and discover that Metro Man is still alive, having faked his weakness and death to pursue his dream as a musician. Megamind and Roxanne attempt to enlist his help against Tighten, but he refuses to help. Metro Man tries to encourage Megamind to become the city's new hero by telling him that a hero will always rise to defeat evil.
