|— Master's Flavor Text • Kirby & The Amazing Mirror|
Master is one of Kirby's special Copy Abilities. It is the final weapon of Kirby & The Amazing Mirror, yet can be used outside of the final battle after beating the last boss, which makes it one of the two final abilities that can do this, the other being Triple Star.
Kirby wields Meta Knight's legendary blade, and with it gains a plethora of new abilities, each of which is useful for obtaining every treasure in the game, except for those that require the Mini or Wheel ability. While it appears very similar to Sword, Master is much stronger than the Sword ability and has more useful properties, more attacks, and maneuvers. So far, it has only appeared in Kirby & The Amazing Mirror, where it could be obtained during the showdown with Dark Mind and in a pedestal in Rainbow Route's Central Circle after beating the game.
The ability's name likely comes from the fact that it is the game's ultimate ability and can be used to get almost every treasure.
Master, unlike other abilities, will stay on screen forever unless it falls down a pit, even when another ability is taken. It also won't disappear if it touches spikes, but it still floats up to the top if in water. The same happens with Triple Star.
|Sword Slash||B||Kirby slashes the enemy.||None|
|Multisword Slash||B + B + B||Kirby attacks with lightning-fast sword slashes that are nearly impossible to see.||None|
|Up Thrust||Up + B||Kirby points his sword up for a split second before stabbing everything above him.||None|
|Sword Spin||B (midair)||Kirby swings the sword quickly in midair, damaging all enemies that come into contact with it.||None|
|Drill Rush||Dash + B||Kirby drills the sword forward at a ridiculously high speed. A move that Meta Knight uses in Super Smash Bros. Brawl is based on this move.||Fire|
|Sword Beam||Hold B + Release B||Kirby slashes and a huge sword beam comes out to damage enemies. Unlike Sword's Super Star version of this attack, it does not deal the standard damage caused by a regular slash, but rather immense damage that goes much further; it is also not limited to only working at full health.||Energy|

|Sword Slide||Down + B or A (ground)||Kirby slides forward with the sword outstretched.||None|
|Final Cutter||Down + B, then before attack ends, Up + B||Kirby jumps in the air and does a flip, then he falls sword outstretched. The attack is basically the same as Sword's.||None|
- Despite the artwork depicting the gem in the handle as bluish, the gem in-game is red. It is Dark Meta Knight's sword with the blue gem. The artwork is likely reflecting an early version of the sword, as said version had a greenish-blue gem.
- This is only one of two sword-based final weapons. The other is the Rainbow Sword. The Master Sword can generate Sword Beams, whereas Rainbow Sword has no native ability to fire projectiles but it can reflect the orbs from Dark Matter.
- Its name may be a reference to the Master Sword, from The Legend of Zelda series.
- Concept art in both the English and Japanese versions of Kirby's 20th Anniversary Celebration Book depict Kirby with a hat, though he doesn't wear one in-game.
- An early version of the game has graphics for Master using Sword Kirby's hat in-game and for the ability icon. Additionally, the gem in the sword's hilt is green.
