Mid-Boss All Stars

Mid-Boss All Stars is a set of Mid-bosses fought in succession in place of a standard boss battle, appearing in Kirby Super Star (and its remake), Kirby & The Amazing Mirror, Kirby's Return to Dream Land, Kirby: Triple Deluxe, and Kirby: Planet Robobot. This pits the player up against three or four mid-bosses. They only appear in The Arenas and The True Arenas, as well as Kirby & The Amazing Mirror ' s Boss Endurance, all being fought in a coliseum.

There are two sets of Mid-Boss All Stars in Kirby Super Star, and a third one in Kirby Super Star Ultra. They are aptly named Mid-Boss All Stars 1, Mid-Boss All Stars 2, and True Mid-Boss All Stars (which only appears in The True Arena).

Trivia

 * The "Mid-Boss All Stars" name is only used in Kirby Super Star/Ultra and Kirby: Planet Robobot.
 * The position in which each Mid-boss spawns in changes depending on the game:
 * In Kirby Super Star/Ultra, odd-numbered Mid-bosses (Chef Kawasaki, Bugzzy, Poppy Bros. Sr., Iron Mam, Mr. Tick-Tock, and Phan Phan) spawn to the left of the player, and even-numbered Mid-bosses (Bonkers, Mr. Frosty, Jukid, Grand Wheelie, and Fire Lion) spawn to the right of the player. The Mid-boss always spawns a set distance away from the player based on the player's position when the previous Mid-boss is defeated (or the initial position of the player in the case of the first Mid-boss of each group). This is the only time where a Mid-boss' position is not set.
 * In Kirby & The Amazing Mirror, all Mid-bosses spawn at the right side of the coliseum, with the first Mid-boss already being present. Mid-bosses like Bombar, Batafire, and Master Hand, all spawn in the air, at varying heights.
 * In Kirby's Return to Dream Land, Mid-bosses spawn on the opposite side of the arena that the player is on. If there are two Mid-bosses, the second one (Bonkers EX in the case of Mid-Boss All Stars 1 EX, and Dubior EX in the case of Mid-Boss All Stars 2 EX) spawns on the same side of the arena that the player is on.
 * In Kirby: Triple Deluxe and Kirby: Planet Robobot, the Mid-bosses have set positions and, like Kirby Super Star/Ultra, alternate between the right and left sides of the arena.
 * All of the Mid-bosses in Kirby Super Star/Ultra ' s Mid-Boss All Stars 1 grant Copy Abilities that can only be obtained from Mid-bosses or Copy Essences.
 * All of the Mid-bosses in the True Mid-Boss All Stars are present in Kirby: Nightmare in Dream Land.
 * Bonkers appears in every game in which a Mid-Boss All Stars group is present.
 * Kirby: Triple Deluxe ' s Mid-Boss All Stars 1 bears resemblance to Kirby Super Star/Ultra ' s Mid-Boss All Stars 1, having Bonkers be the second Mid-boss fought, with the third Mid-boss being a beetle (Bugzzy and Hornhead.
 * The alternate colors used by the Mid-boss All Stars in Helper to Hero are from when they're fought in Cavius.
