Hal Stewart, also known as Tighten or Titan, is the main antagonist of DreamWorks Animation's 2010 feature film Megamind. First, he was the nerdy cameraman of Roxanne Ritchi, who had an unrequited crush on her, but the former had no interests in him. This time, Hal becomes a vengeful, traitorous, and destructive supervillain when he gets hit by the power serum of the titular character in hopes of turning him into Metro City's newest superhero after "destroying" Metro Man and taking over the city, thus becoming Megamind's new archenemy and putting difference aside with Metro Man who faked his death and retired as a superhero.
