* BreatherBoss: Manti Gigas is one of the three bosses that can come after Morpheus. He's also easily the easiest boss in the game, with an easy to break Demon Aura, low stats, and weak backup.
* ThatOneBoss: A good number are subjective, but most players can agree on [[ThePhoenix Ignis]] or [[TheGrimReaper Doom Shade.]]
