List of bosses

This is a list of bosses, powerful video game enemies found in levels. They are usually fought at the end of a level, world, or chapter. Most of the time, the player cannot advance to the next level until the boss is defeated. However, there are certain exceptions to this rule. Bosses are usually much more difficult and take more time to defeat than the other enemies in that level or world. There are several types of bosses:


 * Mini-bosses (a.k.a. mid-bosses or sub-bosses) - Bosses that are sometimes found in the middle of a level, world, or chapter, and are usually just upgraded versions of a normal enemy. An example of a mini-boss is Boom Boom.


 * Chapter bosses - Bosses that appear in RPGs at the end of a chapter. An example of a chapter boss is Tutankoopa.


 * Final bosses - Bosses that are fought mostly near the end of a game, and are supposed to be the hardest boss fought in the entire game. Once the final boss or bosses have been defeated, the game is usually finished. However, there have been times when the game does not immediately end, and the player may need to complete an extra task first (for example, in Mario & Luigi: Superstar Saga). An example of a final boss is Giant Bowser.


 * Optional bosses (a.k.a. superbosses) - Bosses that are most often found in RPGs. They exist in the game, but they do not need to be defeated for the player to beat the game. Sometimes, optional bosses are even harder to defeat than final bosses, as is the case with Culex, The Master, and Bonetail.

The list includes all bosses that appear in the Mario series and related series, with the first game in which they appeared as a boss next to their name. Final bosses appear in bold and optional bosses appear in italics.
