Game:Xemnas

Xemnas is the leader of Organization XIII, and is fought as a boss in both Kingdom Hearts Final Mix and Kingdom Hearts II. In Final Mix he challenges Sora at the Chapel, while in Kingdom Hearts II he fights Sora at both Memory's Contortion and within Kingdom Hearts itself.

First Battle
When the battle begins, Xemnas will ensnare Sora in a field of energy that will slowly drain his health, then teleport to the top of Memory Skyscraper. Sora must rush to the bottom of the building and use the Reaction Command "Facedown" to charge up after Xemnas. Xemnas will leap down to confront Sora as he nears the top. At this point, one of three Reaction Commands appear depending on how close Sora is to Xemnas. The first is "Clash", where they pass each other harmlessly. The second is "Breakthrough", where Sora attacks Xemnas with a single attack. At the last second, the command changes to "Finish", where Sora attacks Xemnas several times and hits him into the side of the skyscraper. You are recommended to hit the Triangle button at "Finish". Note, however, that not hitting Xemnas will cause him to deal damage to Sora.

After the sequence ends, Xemnas will begin his normal attack pattern. He will teleport in an orb of darkness frequently, emerging to attack Sora rapidly with his Ethereal Blades, spinning and flipping to attack from all sides. These attacks can be blocked with Guard, or more easily, Reflect. Xemnas will also project a barrier, blocking Sora's attacks and knocking him back. He can be stunned, so Sora can easily connect combos. However, Xemnas tends to teleport away right afterwards, or if Sora attacks him too many times, he will teleport away in the middle of the combo.

Later in the fight, Xemnas will repeat the opening sequence involving Sora running up Memory Skyscraper. The Reaction Commands for the second time are the same as the first. As well, when weaker Xemnas teleports more often and quicker than before. Overall, Xemnas is not an overly difficult boss, and can be hit with combos with ease. He can be defeated easily as long as the player heals when needed and has some healing items as back-up.

In his respective data battle in Kingdom Hearts II Final Mix, he doesn't start off the battle with the HP drain move. Also, using the "Finish" command on Xemnas while facing him on Memory Skyscraper at the end of the battle leaves him stunned at the bottom of the building with a single HP left, similar to the final battle. This does not happen in the English release.

Energy Core
This is the 1st real battle against Xemnas. Make sure you save before going to the door in Kingdom Hearts, cause there's no turning back. Now, it starts with you on a platform. A bar on the bottom starts filling up, and Dusks start apearing. Hit the Dusk once and move on to the next one. Soon the damage bar will fill with each Dusk sent into the generator. When a notice comes up in the top, use the Reaction Command to jump out of the way of the blast and move on to the right generator. Keep doing that and soon you'll blow up both generators and be on your way.

Armored Controller
This battle is fought before and after the Dragon Form fight, with the only difference being that Sora's only ally in the second battle is Riku.

Final Battle
The first thing Xemnas will do is throw you into the air. He will then deal a series of attacks on you, which you can only dodge by using the Reaction Command, Reversal. After that's done, Xemnas will going into his basic attack pattern.
