A boss is a powerful, non-respawning enemy in Bloodborne. Bosses are easily identified as their name and HP are displayed on screen. Every area in the game has at least one boss, though some can have more.
Though players are required to fight most bosses in order to progress through the game, some bosses are completely optional. Bosses in the DLC are optional.
