Continuity mistake: Whenever Megamind or Minion uses the disguise generator, their normal eye colour always show through their disguises, such as when they both disguise themselves as the Warden (the Warden has blue/gray eyes while Megamind has green and Minion has brown). However, during the final battle, Minion disguises himself as Megamind but he has Megamind's green eyes instead of his normal brown eyes.LizzieWD

Continuity mistake: When Megamind and Minion are arguing about Roxxi, Minion extends his arm with the keys away from Megamind. Megamind presses a button that partially retracts his arm to a few feet long. When Megamind says, "Maybe I don't want to be the bad guy," Minion gasps and raises both hands to his chest. When he leaves to get his things and go, the arm is a few feet long and limp again.
Continuity mistake: When Metroman is"trapped" inside the fake observatory, he says that copper drains his power and then groans in pain. Later, during the flashback of being inside the observatory, after he says that copper drains his powers, he then looks away and starts to laugh.
