Bosses

Bosses are aggressive, difficult mobs that pose a challenge to players. They tend to have much higher health, deal more damage, and attack the player constantly. Killing these types of mobs will either give the player a rare drop or change their Minecraft world in some way.

In Minecraft, there are two bosses: the "main" and final big boss of the game, the Ender Dragon, and a "side" boss: the Wither. Minecraft: Story Mode and Minecraft Dungeons have additional bosses.

Elder Guardians were referred to as a "boss" one time by Mojang staff. They follow the pattern of usually being quite a challenge to kill in survival.
