Honestly, the series has taken a turn to the more complex side; As of KINGDOM HEARTS, Ansem Seeker of Darkness was an all powerful Heartless yearning for Kingdom Hearts, the omnipotent force that would grant him the powers to rule all worlds and plunge them into darkness. As of KINGDOM HEARTS II, it's revealed that Ansem SoD was an imposter and that he was the true Ansem's apprentice, Xehanort. This individual had no recollection of his past before his master found him on his world and that his Nobody, Xemnas, was the leader of Organization XIII, an all powerful entity yearning for Kingdom Hearts, the omnipotent force that would grant him the powers to mold the Realm of Light to his ideals. As of KINGDOM HEARTS Birth by Sleep, Xehanort's past is revealed; he's not a person, but Master Xehanort striving for control in Terra's body, wanting to wield the Xblade to summon Kingdom Hearts, the omnipotent force that would grant him the powres to fulfill his ideal of creating an equilibrium between light and dark. As of KINGDOM HEARTS 3D Dream. Drop. Distance., I don't know what's up with Xehanort. After the time-traveling was introduced, everything seems as if Young Xehanort was corrupted by his older self and became who he is today; a man bent on doing anything, anything, to accomplish his goal, even if it takes killing your best friend. So what are your thoughts on the series' complexity? Has it been furthered?
