Tightenville was the metropolis of Metro City (or Metrocity) before and during Megamind's dictatorship until Hal Stewart usurped him under the name of Tighten. After Tighten' overthrow, Tightenville were 'Metrocity' again and were threatened again when The Doom Syndicate tried to steal both Metro Man and Megamind's DNA to take over it, but they were defeated by Megamind.
