In the computer wargame StarCraft, a hero unit is a unit with greater than normal abilities. Oftentimes it represents a character in the plotline of the game -- for instance Jim Raynor, Edmund Duke, Fenix, Tassadar, or the Infested Kerrigan. However, especially among the Zerg, hero units are simply stronger than normal versions of a common unit -- such as the Hunter Killers or Torrasque.
