Boss

Bosses are the strongest enemies in the Kirby series and are usually fought at the end of each level. Oftentimes, a boss character also plays a major role in the game's story, though not always. Boss characters always have life meters that need to be depleted to defeat them.

Fighting bosses
Usually, a boss will have some sort of attack that can be inhaled and spit back at it. Some bosses have attacks that give copy abilities.

List of Bosses
Bosses' presence in several places are not listed, for various reasons:
 * Boss Endurance events - as they are a rehash of all boss fights in a game title. The Arena and The True Arena are covered, as they are Sub-games of Kirby Super Star and Kirby Super Star Ultra.
 * Meta Knightmare Ultra - A re-run through all the minigames in KSSU as Meta Knight instead of Kirby, with the Old Tower and consequently Chameleo Arm not available, and fights new boss Galacta Knight.
