Bosses are common encounters in the Kingdom Hearts series. They are more difficult and often larger than the lesser enemies. Bosses usually have a significant role in the storyline, but others simply serve as challenges with little plot connection in some worlds.

Notes and references
- ^ Ansem, Seeker of Darkness appears to have characteristics of both Emblem and Pureblood Heartless, in both his human and world forms. In both forms, he carries the Heartless emblem on his chest, though in human form it could possibly be an article of clothing. Notably, though, the similar outfit worn by Master Xehanort does not possess the emblem. Furthermore, the shadowy symbiote attached to him in both forms possesses the "hollow heart" shared by many other Pureblood Heartless. Though it is uncertain what the situation of this Heartless is, it is possible that this makes him both an Emblem and Pureblood Heartless.
