Description: Old - yes, Evil - yes, Bald - yes, Amazing fights - yes. Xehanort is the prime antagonist of Kingdom Hearts and almost 90% of the time he is or one of his variants are the last boss of each game. In some way Master Xehanort is responsible for all of the events in the story, such as the creation of the Heartless. Do not let his appearance fool you though, Xehanort is bad to the brittle bone and has thought out his master plan almost all too well, planning out a back up scheme for every little possibility - and he is also the prime reason why the Kingdom Hearts storyline became so hard for some people to follow that some might actually have to read about what happened after playing the game. The picture to the right is of Ansem, Seeker of Darkness, who was the douche that possessed Riku close to the end of the original and was the last boss of that game, however his fight was not merely as impressive as Xemnas, the nobody on the left. Xemnas is quite literally a Nobody, a being that shouldn't exist and has no heart, although his fight is by far the most epic in the franchise so far in my eyes, he is quite ridiculous - he believes that the nothingness has power, but that is ok because the fight was still epic, and I got to bear witness to perhaps the  one of the most epic attacks ever in a videogame. Xehanort is a highly calculating individual that has thought out his scheme extremely well, making him a great villain, but he might actually be more successful if he was not OLD! Oh wait I forgot about Young Xehanort - a version of Xehanort from when he was a teenager with the power to time travel, HOW MUCH SENSE DOES THAT MAKE!? If he traveled into the future, then he would know how it would turn out AND he would create a Time Paradox if I am understanding the rules of Time Travel correctly, which should alter how he ends up winning in the end (I think). Personally I don't think Young Xehanort was a necessary addition to the variants of Xehanort, but I can live with it despite Time Travel is so overwhelmingly complicated. Overall, Xehanort is a cunning, calculating villain who see's details and will do everything to the very fiber of his soul to get what he wants - so far as to go and split himself into a Heartless and a Nobody, knowing somebody would try to stop him.
