There is no Anti hero, that's just wordplay. The Hero's theme is the main point we're sticking to here, whether they be superheroic or an anti hero doesn't matter so much as that they're the main protagonist. Any hero theme, whether it be the main theme to a series (Ezio's Family from Assassin's Creed), a specific character's theme from a game (Shieks Theme from Ocarina of Time, though Zelda's Lullaby would work), or a level theme that references the main theme (The Guardian's Theme from Darksiders 2 since it's just a rearrangement of the main titles).
