No Heart

No Heart is an optional boss exclusive to Kingdom Hearts Birth by Sleep Final Mix. He is a data simulation of Xehanort in his Keyblade Armor, and he is fought within the "Foresight unto Darkness" battle in the Mirage Arena.

Appearance
No Heart wears a suit of Keyblade Armor branded with a single Nobody emblem centered on the torso, two protruding from his greaves, and two wrapping over his boots. His crown and shoulder pad are gold, while the rest of the armor is colored in light shades of blue and silver. He has two silver belts on his waist and what seem to be white feathers on his right shoulder in place of a spiked pauldron. Several cords crisscross in front of his torso, connecting a pair of baggy sleeves to massive, oblong pieces of armor worn on each arm. No Heart removes both of these sleeves and the straps before fighting. No Heart's faceplate is beak-like in structure and he wears clawed gauntlets. He also wears black pants underneath the armor. He wields Master Xehanort's Keyblade in battle. This Keyblade Armor is later worn by Xemnas in his Armored Controller form.

Like "Another", "No Heart" is an anagram of Xehanort without the X in the name.

Trivia

 * The music that plays during No Heart's battle is Forze dell'Oscurita — Italian for "Forces of Darkness" — and is a remix of Forze del Male and Darkness of the Unknown, the battle themes of Ansem, Seeker of Darkness and Xemnas, respectively.
