[[caption-width-right:256:[[VideoGameLongRunners "Mr. Mario, I feel that you and I are destined to do battle, again and again, for as long as the gods see fit."]]]]

A climactic confrontation with a unique, stronger than average, and often monstrous enemy creature known colloquially as a "boss". It has several important features, depending on the genre of game in which it is found.

In old-school ShootEmUps and 2D {{Platformer}}s, the boss comes at the end of a level or series of levels (commonly called a "world"). He will often require a [[PuzzleBoss special trick]] to defeat, or have a targetable WeakSpot.

In {{FPS}}, [[ThirdPersonShooter 3PS]]'s, and 3D {{platformer}}s, they divide up the game. They might be common or uncommon, gigantic or small, complex multi-stage affairs or simple exercises in [[HeroTrackingFailure circle strafing while shooting]].

In {{RPG}}s, they wait at the end of dungeons (though the larger dungeons may have multiple boss fights). They have a mountain of HitPoints. If they're [[FinalBoss the last one]], you'll most likely fight them [[SequentialBoss more than once]]. Most have a [[OutsideTheBoxTactic specific weakness]].

In a FightingGame, the boss is simply the last character you fight, in that even when the rest of the battles have you going up against a randomly-selected opponent, the boss is always the same. The boss is typically not a playable character (though circumstances may allow him to be unlocked later), and tends to be the [[SNKBoss most difficult opponent]]. Occasionally, the penultimate battle will ''also'' be against a "boss". (The penultimate opponent is often dubbed a "MiniBoss".)

Often accompanied by unique, tense, action-packed BattleThemeMusic. Sometimes, special {{Fight Woosh}}es and {{Fanfare}}s are also made just for this event.

Note that in some games, the boss isn't ''always'' at the end of any given level or dungeon.
