Kingdom Hearts Birth by Sleep Final MixEdit

A physical manifestation of what remained of a Keyblade Master's powerful thoughts and feelings.


The Armor of the Master is a sentient suit of Keyblade Armor that wields Master Eraqus's Keyblade in battle. Its torso is covered of dull, faded green armor and sports a small Mark of Mastery symbol in its center. The rest of the armor on its arms, legs, and chest are predominantly bronze and silver. Its pointed, armored boots are black and gold and its upper arms and thighs have wide, supplementary armor with gold edges covering them.

The Armor of the Master's helmet is silver with a gold chin with jagged "teeth" and a Mark of Mastery symbol of the same color adorning its forehead. The helmet is also decorated by three long, thin, silver pikes on its top and sides. Its hands and neck are covered by a black material.

The Armor of the Master's design is a possible reference to the ō-yoroiarmor worn by samurai.


The Armor of the Master's name reflects how it is the Keyblade Armor of Terra, Ventus, and Aqua's master, Eraqus.


  • The music that plays during the battle with the Armor is "Master, Tell Me The Truth", a remix of the Land of Departure battle theme "Future Masters".
