No Heart

No Heart (ノー・ハート) is a boss exclusive to Kingdom Hearts Birth by Sleep Final Mix that appears in the Mirage Arena. It is fought in the "Vista to Darkness" Arena Mission. During the battle, it sits on a throne in the Throne Room of the Land of Departure and wields Master Xehanort's Keyblade. It is the same armor that Xemnas wore during his final battle with Sora and Riku in Kingdom Hearts II.

Design
No Heart's armor is adorned with dozens of Nobody symbols. His shoulder pad (he only has one, on his left shoulder), helmet, crown, boots, knees, and breastplate all sport these designs. His crown and shoulder pad are gold, while the rest of the armor is colored in light shades of blue and black. He has two white belts on his waist and what seems to be a white tuft of fur on his right shoulder in place of armor.

No Heart's faceplate is beak-like in structure and he wears clawed, metal gloves.

It's name, "No Heart" is an anagram of Xehanort without the X in the name. This is seemingly opposite of Organization XIII member names being anagrams of their previous names with an "X" added.
