After decades as a villain, Megamind accidentally defeats Metro Man and finds himself alone. With reporter Roxanne Ritchie's help, he discovers heroism is about showing up, not power. He saves the city, befriends his former nemesis, and builds a family of Xerxian survivors. He learns to forgive himself, falls in love, and creates a garden of his dead homeworld's plants growing hope, belonging, and a future where lost children finally come home.
