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.

Kingdom Hearts Final Mix
At the start of this battle, immediately Lock-On and summon Tinker Bell. This will minimize the damage Xemnas can do to Sora. He will immediately execute an energy-ball attack, the balls exploding into orb-like, damaging force fields. While it is advised that the player has their most powerful abilities equipped, they must be careful at close range, as Xemnas will counter with a damaging shield technique or a powerful slashing combo. As the player must also be wary of their MP, Elixirs and Megalixirs are strongly recommended.

After about three quarters of Xemnas's pink HP Bar have been depleted, the hooded Nobody will begin to teleport around the battlefield, ultimately increasing his speed. Escape his energy ball or slash/shield attack by keeping track of the dark cloud that surrounds him. Once Xemnas hits his orange HP Bar, however, battle difficulty increases even further. Xemnas will summon a ring of blue Ethereal Blades in the air before him, the blades firing at Sora when Xemnas gives the command. This technique can be avoided via Dodge Roll. When his yellow bar is almost completely depleted, Xemnas shrouds the field in darkness, surrounding himself with energy. Long-range lasers will then fire from him in all directions. Remain close to Xemnas to avoid as much damage as possible. Another option of escape is to use the Glide tactic.

From this point forward, Xemnas's most basic attacks gain more strength, the Nobody now summoning a ring of red blades rather than blue. The effect of this attack is still the same, yet damage is increased. Xemnas's final and most dangerous tactic is an HP-draining attack, messing up Sora's commands. Once Sora's HP hits zero, Tinkerbell will revive him. As she can only be used once, Sora now must rely even more on his Curaga spell. So long as the player heals periodically and follows strategy options mentioned above, Xemnas should fall rather easily.

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.

Replica Data Battle
In his respective data battle in Kingdom Hearts II Final Mix, Xemnas 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. Merely repeat tactics used in the fight against the true Xemnas, and he shall fall. This is only the first portion of the battle, Sora then forced to challenge Xemnas's final form with Riku as a Party Member.

Energy Core
The final battle with Xemnas begins. The player must make sure that he or she has saved the game before entering the battle, as this option will not be available again, and there is no turning back. As soon as the battle starts, Xemnas begins to bombard Sora with buildings. Use the Reaction Command to avoid damage, and then pass through the doorway before you into the next area. Run forward and use the "Skyscraper" command to reach Xemnas's massive Dragon Ship. The player must now knock several Time Bomb Nobodies into the power generators of the ship. The player must use "Stunt Dodge" to dodge both the generator's laser attack and explosion upon destruction respectively.

Sora then finds himself in the main core of the ship. Attack the core, dodging aerial attacks from the ship's "claws" and the lesser Nobodies that spawn once the core surrounds itself with a protective barrier. It should be noted that only by destroying the Nobodies does the core become open to attack once again. Use the "Proceed" Reaction Command to enter the next phase of the battle.

Armored Controller
First Incarnation

After destroying the main core of the Dragon Ship, Sora is faced with an armored Xemnas. The Nobody will use a massive sword to deal damage, having a long range. Not only does Xemnas have acces to this attack, but those of past defeated Organization members, as well. He can summon Demyx's Water Forms, which can deal great damage, but give much-needed HP Balls upon defeat. Xigbar's Sharpshooters may fire lasers while a ring of fire and Axel's Eternal Flames appear on the ground. Xaldin's lances will cause wind damage, Saix's Lunatic able to knock Sora back in a powerful shockwave. Xemnas may also select Luxord's Fair Game to damage Sora, too. Merely dodge these relatively weak attacks, and show Xemnas no mercy. Drive Forms can be used for only this portion of the battle, and greatly increase the rate at which Xemnas's HP is depleted. Heal periodically. It should be noted that should the player fall, King Mickey is available to revive Sora.

Second Incarnation

Xemnas also appears yet again in his armored form in the third stage of the final battle, after the destruction of the Dragon Ship.

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.
