Terra-Xehanort

Terra-Xehanort (also referred to as Terranort) is the person that came into being after Master Xehanort took possession of Terra’s body and shortly thereafter lost his memories. Turning up unconscious in Radiant Garden after Aqua used her Keyblade and armour to push him out of the Realm of Darkness following their epic battle, Terra-Xehanort was taken in by Ansem as an addition to his five apprentices. Xehanort was a willing test subject in Ansem’s experiments into the human heart, and eventually started doing his own inhumane experiments in secret on numerous Radiant garden citizens with the other apprentices. These experiments resulted in the citizens turning into Heartless, which were then trapped deep within the lower depths of the castle. Terra-Xehanort was the “somebody” from whom Xemnas and Ansem, Seeker of Darkness were created. He was first seen in Kingdom Hearts II, and his backstory was revealed in Kingdom Hearts Birth by Sleep.
