{{Q|I can not feel—sorrow... No matter what misery befalls the worlds. No matter what you think, what you feel, or how you exist.|Xemnas to Sora}}
'''[[Xemnas]]''' is the leader of [[Organization XIII]], and is fought as a boss in ''[[Kingdom Hearts Final Mix]]'' and the final boss of ''[[Kingdom Hearts II]]'' and [[Sora]]'s story in ''[[Kingdom Hearts 3D: Dream Drop Distance]]''. 

In ''Kingdom Hearts Final Mix'', he challenges Sora at [[Hollow Bastion]], while in ''Kingdom Hearts II'' he fights Sora at both [[Memory's Contortion]] and within [[Kingdom Hearts]] itself. 

In ''Kingdom Hearts 3D: Dream Drop Distance'', he battles Sora in [[The World That Never Was]]. 

In ''Kingdom Hearts III'', he battles Sora, [[Riku]], and [[Mickey]] alongside [[Ansem, Seeker of Darkness]] and [[Young Xehanort]] at the [[Keyblade Graveyard]]. A data replica of him is also an optional boss in ''[[Kingdom Hearts III Re Mind]]''.

==Design==
Xemnas commands a gigantic and draconian battleship during several parts of his final battle with Sora and Riku. The dragon has a small main body, a long, segmented neck, and a round head with numerous tall, thin spikes lining it. Its mouth is somewhat beak-like and an armored Xemnas sits on a throne on the top of the head. The throne is adorned with large spikes and other additives that resemble the [[Nobody]] emblem, and large, seemingly organic, orange objects connect Xemnas to the battleship. The dragon's wings are thin, angular, and each is emblazoned with a black Nobody symbol at the joint. Each wing also has several thin, black and white "feathers" with tips resembling the Nobody logo. Its thin arms end in three-fingered, segmented hands and each arm is lined by four blue diamond-shaped spikes of increasingly smaller size. In place of legs, the Dragon has two massive, conical engines with two smaller engines on either side of the main ones. It also has a long, thin tail with four conical objects connected to its tip. The dragon is predominantly colored in light shades of silver and metallic blue.

While commanding the dragon, Xemnas dons [[Master Xehanort]]'s [[Keyblade Armor]], which bears a striking resemblance to [[No Heart]]. The armor is adorned with dozens of Nobody symbols. The shoulder pad on his left shoulder, helmet, crown, boots, knees, and breastplate all sport these designs. His crown and shoulder pad are gold, while the rest of the armor is colored in light shades of blue and silver. He has two silver belts on his waist and what seems to be white feathers on his right shoulder in place of armor. Several cords criss-cross in front of his torso, connecting to massive, oblong pieces of armor worn on each arm. Xemnas's faceplate is beak-like in structure and he wears clawed, metal gloves. He also wears black pants underneath the armor. Perhaps the most striking features of this armor are the oddly-shaped "sleeves" that are attached to each of Xemnas's arms. They are a mixture of red, orange, yellow, and white. He also wears a massive, similarly-colored cape that seems to connect him to the dragon.

In the final section of his battle with Sora and Riku, Xemnas's appearance is unchanged, save for his cloak. His once all-black cloak is now a white one covered in black designs, many of which resemble the Nobody logo.

The Armored Controller's name reflects the armor Xemnas wears and his command over the dragon.

Early concepts for the Xemnas battle included two gargantuan Nobodies in place of the dragon, formed from Dark City rather than the Castle That Never Was: {{nihongo|'''[[King]]'''|キング|Kingu}}, which had a vaguely humanoid upper body adorned in Nobody sigils and wore an immense crown, and {{nihongo|'''[[Kentauros]]'''|ケンタロウス|Kentarousu}}, which resembled a dilapidated version of the King attached to a quadrupedal lower body, with the crown becoming a spiked ruff.

==Strategy==
===''Kingdom Hearts Final Mix''===
[[File:The Unknown 01 KH.png|thumb|right|The Unknown confronting Sora, Donald, Goofy, and the Beast in Hollow Bastion.]]
At the start of the battle, immediately [[Lock-On]] to the Unknown, summon [[Tinker Bell]], and prepare any variant of [[Aero]] available (preferably as a shortcut). This will minimize the damage the Unknown can do to Sora. He will immediately execute an energy-ball attack, which explodes into orb-like, damaging force fields. While it is advised that Sora has his most powerful abilities equipped, be careful at close range, as the Unknown will counter with a damaging shield technique or a powerful slashing combo. As Sora must also be wary of his [[MP]], [[Elixir]]s and [[Megalixir]]s are strongly recommended.

After about three-quarters of the Unknown's pink [[HP]] bar have been depleted, he 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; it is possible to stun him with {{c|Gravity|element}}-based attacks before he reappears. He also gains a deadly ability in which he curses Sora and the [[party]], draining their health and changing the [[Command Menu]] into a rapid roulette solely showing '''Shock''' and '''Release'''. Wait for Release to appear in the menu before selecting the command to end the curse. If Shock is chosen, Sora's health falls considerably. Tinker Bell can revive Sora to full health if he falls, but that means that once the curse is dispelled, [[Curaga]] is more essential. To avoid this attack, [[Dodge Roll]] at just the right moment when the Unknown teleports, or cast Curaga, as [[Leaf Bracer]] will shield Sora from getting cursed.

Once the Unknown hits his orange HP Bar, however, the battle difficulty increases even further. the Unknown will summon a ring of blue [[Ethereal Blades]] in the air before him, which fire at Sora when the Unknown gives the command. This technique can be avoided through the use of Dodge Roll. When his yellow bar is almost completely depleted, the Unknown will unleash his ultimate attack, which resembles [[All-Vanity]]. He will shroud the field in [[darkness]], surround himself with energy, and fire long-range lasers in all directions. Remain close to the Unknown to avoid as much damage as possible, where he'll only hover in front of Sora and thus one only needs to merely watch for the direction of the lasers in order to properly avoid them. Another option of escape is to use [[Superglide]]. Once the Unknown uses his ultimate attack for the first time, his basic attacks become more powerful, and the Ethereal Blades he fires now glow red.

The Unknown also proves more difficult than [[Sephiroth]] due to attacking relentlessly, which in turn leaves very little chances to make him flinch from basic combos. {{c|Percentage|element}}-element attacks such as [[Gravity]] spells, [[Gravity Break]], [[Zantetsuken]] and even Simba's Proud Roar will stun the Unknown with a surge of overloading power, causing him to cringe and shiver a bit in pain (Sora will also receive [[Tech Points]]) and leaving him briefly vulnerable to attack. Be ready to use Dodge Roll to avoid his counterattack. The safe way to do this attacks him exactly three hits after Gravity hits him, then Dodge Roll and repeat Gravity. Also, cast the spell on him at the right time, as the Unknown might have a chance of shaking any Gravity-based move off during an attack animation, since he'll still go through with his move even if Tech Points are gained.

The Unknown will usually also flinch to air combos, so keep that in mind when moving in to attack him, especially if stunned by any Gravity-based damage as aforementioned. Be sure to remove any [[Combo Plus]] abilities to access the combo finishers sooner before the battle, enabling Sora to [[attack]] with higher chances of not being interrupted. Prepare [[Curaga]] just in case Sora needs healing. With good timing, it is also possible to slide past or underneath the energy balls he fires with [[Sliding Dash]]. Should that connect, remember to combo from that to use a ground combo finisher if needed.

The Unknown's final phase tends to leave fewer openings to attack him head-on and to stun him, but there's often a free chance to make him flinch whenever he finishes using his strongest attack.

Another strategy is to involve having a high-enough MP bar + all 3 Cheer abilities across the party; summoning a summon that removes both party members from the battlefield prevents the Unknown from ever performing his infamous Invintation to Nothingness technique (Mushu is likely the one exception while Sora remains completely invincible using Dumbo). In regards to using Simba however, Level 5 Proud Roar is not as effecient as Gravity magic (especially if upgraded fully to either Gravira or Graviga) or Zantetsuken despite also being percentage-based, as well as being too slow to catch the Unknown in unless he's in the middle of teleporting.

===''Kingdom Hearts II''===
====First Battle====
[[File:Versus Xemnas KHII.png|right|thumb|Xemnas faces down Sora within the [[Memory's Contortion]].]]
When the battle begins, Xemnas will use his '''Invitation to Nothingness''' attack, which ensnares Sora in a field of energy that will slowly drain his health, then he teleports to the top of [[Memory Skyscraper]]. Sora must rush to the bottom of the building and use the [[Reaction Command]] "Facedown" to break the energy field and run up the building after Xemnas. Xemnas will leap down to confront Sora as he nears the top. At this point, one of three Reaction Commands appears 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 slams him into the side of the skyscraper. It's recommended to hit {{Button|t}} at "Finish". Note that '''missing all three''' Reaction Commands will cause Xemnas to attack Sora with Building Fall.

After the sequence ends, Xemnas will begin his normal attack pattern, very akin to how he fights in ''Kingdom Hearts Final Mix'' but more limited in terms of moveset. He will teleport in an orb of darkness frequently, emerging to attack Sora rapidly with his Ethereal Blades, spinning, flipping and kicking 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 afterward or if Sora attacks him too many times, he will teleport away in the middle of the combo when reaching his retaliation point/Revenge Value.

However, Xemnas has more aggressive patterns even with his limited moveset and his attacks have some rather high tracking. When trying to counterattack him after blocking, there are specific windows in which either Counterguard or Reflect can get him to flinch.

When reduced to 35-10% HP, 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 he gets weaker, Xemnas teleports more often and more quickly than before.

====Data Rematch====
[[File:Versus Xemnas's Replica Data KHIIFM.png|thumb|right|Xemnas's Replica Data of the first battle appears before Sora in the [[Garden of Assemblage]].]]
The first phase of Xemnas's Data Rematch is a recreation of Sora's one-on-one duel in Memory's Contortion. Simply use the same strategy used against the real Xemnas. However, there are four differences. The first three are simple: Xemnas has more health, does not use Invitation to Nothingness on Sora until reduced to 30% HP, and is left with 1 HP if Sora uses '''Finish''' during '''Facedown'''. The fourth is the addition of an enhanced Dual Blade attack when Xemnas gets close to half health, where the arena darkens and he follows Sora closely, thereby making it much more difficult to evade his attack.

In ''Kingdom Hearts II Final Mix'', Xemnas's Ethereal Blade attacks have a wider hitbox, his second and subsequent uses of Invitation to Nothingness occur when reduced below 15% HP, and when struck by Invitation to Nothingness, Sora's HP only starts dropping when Xemnas moves to the building.

Regardless, Xemnas is far more aggressive with his blade attacks, and the DM version of his Dual Blade move gains the ability to track Sora even in midair, making it hard to glide away from him as often unless Sora already has made distance. Critical Mode and/or Level 1 runs may often involve being easily chipped away to death if the player fails to foresee any of his moves due to him interchanging between Combo Attack and Dual Blade. While Combo Attack can be easily Reflected twice for free damage and an opening, it can be dangerous to see Dual Blade coming which can break the possible Revenge loop.

====Final Battle====
=====Energy Core=====
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 into the next area. Run forward and use the "Skyscraper" command to reach Xemnas's massive Dragon Ship. Sora must now knock several [[Bomb Bell B]] Nobodies into the power generators of the ship and then use "Stunt Dodge" to dodge both the generator's laser attack and explosion upon destruction.

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. 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 faces Xemnas in armor. Although he remains sitting on his throne, the Superior wields a massive sword, and can also channel the attacks of the game's fallen [[Organization XIII]] members.

When reduced to 70% HP, Xemnas summons five of [[Demyx]]'s Water Forms, which drop [[HP]] [[prizes]] on defeat as well as allowing Sora to use the '''Wild Dance''' Reaction Command. Xemnas can deploy the weapons of fallen Organization members as well, including those of [[Xigbar]], [[Xaldin]], [[Saïx]], [[Axel]], and [[Luxord]]. Watch for when these weapons appear near Sora to avoid getting caught off guard. Additionally, Luxord's [[Fair Game]] can appear to attack Sora if he passes over the image of a card on the floor.

When an attack causes Xemnas to flinch, he counters with '''Sweep Away''', then launches attacks with weapons deployed in various locations. He will also launch two simultaneous attacks with deployed weapons when reduced to 40% HP.

Only [[Final Form]] is recommended for this portion of the battle and can greatly increase the rate at which Xemnas's HP is depleted. Other forms will most likely trigger [[Antiform]] due to the x10 Anti Point Modifier of this battle. Should Sora fall, King Mickey may appear and give him a second chance.

;Second Incarnation
[[File:Versus Xemnas (Armored Controller) 2 KHII.png|right|thumb|Armored Xemnas battles Sora and Riku for the second time on his massive Dragon Ship.]]
After the fall of the massive Dragon Ship, it rejuvenates and teleports Sora and Riku to an alternate dimension. They fly to the head of the ship, where they find the stationary, armored Xemnas awaiting them yet again. He will attack with a long-range sword swipe as in the last battle, dealing a lot of damage on contact. When reduced to the HP thresholds of 80%, 50%, and 30%, Xemnas blows Sora and Riku far away and fortifies his defenses with a giant shield. The first and second time Xemnas uses this attack, the shields will automatically deactivate after two minutes. 

During this fight, Sora gains access to an enhanced version of [[High Jump]], [[Glide]] and [[Aerial Dodge]]. The latter ability can be used infinitely for as long as Sora is in midair. Riku will also heal Sora with [[Cure Potion]] if his HP falls below critical.

Xemnas will bombard Sora with lasers and buildings, so use the Reaction Commands to get back to the ship. Failure to do so will result in Xemnas blowing Sora away and dealing minor damage. Once this is done, immediately and repetitively use [[Aerial Dodge]] in order to dodge Xemnas's next tactic, which allows him to summon snowflake-shaped energy that fires lasers and is unavoidable. Should this not be done, Sora can attempt Aerial Dodge again or merely allow damage and then fall to the point where he can safely [[glide]] back to the ship. Sora may alternatively use Thunder spells with the [[Magic Lock-On]] ability to deal damage to Xemnas without needing to land on the Dragon Ship's head. In other cases, Sora can teleport back to Xemnas by using Trinity Limit.

When Xemnas is reduced to 50% HP, these lasers will continue to fire as Sora grapples with Xemnas. Be aware that he may summon a damaging shield, just as he did in his previous battles. 

In ''Kingdom Hearts II Final Mix'', Xemnas's '''Laser''' and '''Magic Circle Laser''' attacks have a wider hitbox.

{{rc|c}}

=====Xemnas (Dragon Form)=====
This fight pits Sora and Riku in a [[Gummi Ship]]-style battle on a [[Sidecar Glider]] against a massive Dragon Ship, which is piloted by Xemnas. Sora and Riku have access to an Energy Gauge, visible on the top left of the screen. Sora can execute a three-strike [[Attack]] combo with {{button|x}}, use Shoot to fire lasers with {{button|s}}, and use Drain to defend against lasers with {{button|c}}, filling the Energy Gauge. Once the gauge is filled, Sora and Riku gain access to the powerful Megalaser Reaction Command. Using it with {{Button|t}} will, if not completely, drain large portions of the ship's HP without fail. 

During the fight, Bomb Bells, Speeders, and Spiked Rollers will appear to attack Sora and Riku. If a Bomb Bell remains undamaged for six seconds after spawning, it moves to where Sora was at that time and uses Explosion. If it approaches, move away to avoid its blast. If Bomb Bells appear near Sora, he can use Shoot to deal damage, but the Attack option offers higher accuracy. Speeders uses Shot while moving forward, fly off-screen, then do a U-turn to return. If you see it fire its lasers, be sure to use Drain to absorb them. When a Spiked Roller appears, it hovers in place and uses Homing Laser, then flies away immediately afterward. Its Homing Laser is quick enough to hit Sora as the Drain barrier forms, so don't hesitate to set up Drain in advance. The shoot command should only be used against enemies that are out of range. All enemies that bombard the ship via Shoot deal massive damage.

Sora must first tackle the Dragon Ship's tail. Utilizing a combo of the commands mentioned above, this should hardly be a challenge. Xemnas may fire a large array of missiles and since Sora cannot heal in this battle, be sure to dodge by flying in circles to each corner of the screen.

After destroying the tail, Sora must defeat the "legs" of the ship. Megalaser will come in handy here and also fly in circles to dodge the snowflake-shaped lasers that are fired. After defeating both of these limbs, Sora can proceed to the wings.

Before the first wing can be destroyed, Xemnas will use Magic Circle Laser as well as Missile. Both tactics can be dodged via flying to each screen corner. Once this is done, the command process repeats itself yet again. Defeat both wings in order to clear the battle and progress.

=====Final Form=====
[[File:Versus Xemnas (Final Form) KHII.png|thumb|right|Xemnas in his Final Form, about to fight Sora and Riku.]]
{{Q|Anger and Hate are supreme...|Xemnas to Sora and Riku}}
Xemnas will first throw Sora and Riku into the air, leading to a series of aerial slash attacks and roundhouse kicks. It is possible, however, to avoid being thrown in the air if Sora has Reflega in the shortcut menu and uses it immediately after the battle begins. These tactics can be dodged by using the "[[Reversal]]" Reaction Command. To deal minor damage to Xemnas as he teleports around, manually select the [[Trinity Limit]] ability. This approach would then lead to the "Block" Reaction Command. It is also possible for a cinematic to play where Xemnas knocks Sora's [[Keyblade]] away. At this time, activate the Reaction Command "Defend", where Riku tosses Sora's Keyblade back to him and they both force Xemnas away.

Eventually, Xemnas will allow Sora and Riku to the dropdown. He will then teleport around the battle area, shooting threads of dark energy that can be dodged via Reversal. When Xemnas reappears, he uses a clone in an attempt to trick Sora. Attacking the wrong Xemnas will result in the true Superior slashing with his Interdiction or dealing a devastating roundhouse kick.

As his HP depletes, Xemnas will shoot energy balls that explode to both block and cause damage. When Xemnas's HP is reduced to 50%, he begins to teleport rapidly, encircling Sora and Riku with lasers continuously and in various configurations. He and his clone may then appear together or separately to shoot at Sora. These moves can be avoided via Reflega or [[Guard]] and if willing to be wasteful while possibly dealing damage, a [[Limit]]. Once these tactics are completed, Xemnas will trap Sora, slowly draining his HP. This forces the player to control Riku, who only can jump, cast [[Dark Aura]], and attack. While Xemnas drains Sora, his clone will attack Riku with energy balls, slashes, and even the damaging shield tactic. The clone can be annoying, but Dark Aura will stun him just a little. Use this time to run to the real Xemnas and Sora, using Dark Aura every three steps until close to the true Xemnas. Jump to him and execute the Reaction Command in order to free Sora, stunning Xemnas. This leaves Xemnas open to major damage. However, the attack can be completely avoided: when Xemnas says, "Can you spare a heart?", cast Reflect or initiate a Limit just as Xemnas casts his curse on Sora. If Sora is out of MP, a well-timed Dodge Roll can also evade this attack, though this is only recommended when out of MP as it requires very precise timing.

Xemnas will then repeat the throwing technique used at the battle's start, as well as his normal attack pattern. When reduced to 10% HP, Xemnas uses his '''Multi Shot''' attack; he fills the battlefield with lasers, shrouding the area in darkness. At this point, repeatedly mash {{button|x}} and {{button|t}} in order to keep Sora and Riku alive. Failure to do so will spell certain death. Once the area is cleared of lasers after 30 seconds, a brief cinematic is shown, eventually permanently stunning Xemnas and reducing his HP to 1. From there, simply perform a combo finisher, [[magic]], or a Limit to finish Xemnas off.

Riku will heal Sora when his HP is low. [[Item]]s still should be brought into battle, as it is best to be hit by Xemnas's drain attack with a full bar of HP. [[Ether]]s are also good for restoring much-needed MP. While Xemnas's final attack brings him to 1 HP, Sora can deplete his HP to 1 before the attack is executed as well. Riku cannot die in this battle, because he is needed for the entire battle. The only time that Riku can die is when Xemnas starts to drain Sora's HP. If Riku is defeated before he reaches Sora, it is a [[Game Over]].

In ''[[Kingdom Hearts HD 2.5 ReMIX]]'', the "Reversal" Reaction Command can show up less frequently. The best way to avoid Xemnas's Invitation to Nothingness in this version is to activate [[Session]], providing Sora and Riku invincibility during the attack. This problem was fixed in ''[[Kingdom Hearts HD 1.5 + 2.5 ReMIX]]''.

In ''Kingdom Hearts II Final Mix'', Xemnas's Spark Wall attack knocks Riku to the side, and he recovers from flinching more quickly. Additionally, Thorn Beam has a larger hitbox and the Reversal Reaction Command is displayed for a longer period.

====Data Rematch====
The second phase of Xemnas's Data Rematch recreates the final battle. Once the first battle is over, Riku joins the [[party]], giving Sora a chance to change his equipment between battles. After exiting the menu, the second battle starts. If Sora is defeated in the second battle, he will have to redo the first battle.

Use the same strategy used in the final battle against the real Xemnas. However, Xemnas's pattern is different. For instance, he now uses the Bind Attack multiple times. Sora should bring [[Elixir]]s and [[Hi-Potion]]s to the fight for healing. If Sora is in [[Limit Form]], Xemnas forgoes using Bind Attack and instead begins his attack sequence where he throws Sora into the air.

Xemnas uses his Bind Attack when reduced to 75% HP, begins using his Shot attack when reduced to 50%, and uses Multi Shot when reduced to 5% HP.

===''Kingdom Hearts 3D: Dream Drop Distance''===
{{Q|As your flesh bears the sigil, so your name shall be known as that...of a recusant.|Xemnas to Sora}}
[[File:Versus Xemnas KH3D.png|right|thumb|Xemnas taunts Sora before engaging in combat.]]
It is advised to bring two Curaga commands into battle to ensure maximum healing potential and cancel out the wait for command reload time should Sora's HP need replenishing. Do not equip [[Slide Roll]] but stick instead to the regular [[Dodge Roll]], due to the latter giving more invincibility. Also bring [[Spirits]] that have Curaga and the [[Haste]] Support Magic to not have problems with the reload time, while having ones that can cast [[Spirit Roar]] in order for Sora's damage to increase temporarily. Use Flowmotion to Sora's advantage, and the battle should end with minimal difficulty. It is a necessity to enter this fight with a full [[Drop Gauge]] (after using one to two [[Drop-Me-Not]]s), especially at lower levels.

At the start of the battle, Xemnas will use Building Throw at Sora while teleporting to the end of the arena, then follows by three more buildings. Perform carefully-timed [[Dodge Roll]]s to avoid them and reach Xemnas quickly. If left alone during his normal phase, he will casually walk up to Sora like in prior games but will start to actively attack in response to Sora's offense.

Xemnas is incredibly swift and frequently travels around the battlefield either inside an impenetrable sphere of darkness or by teleporting from place to place, attempting to catch Sora from behind, and may also use it relentlessly in order to completely nullify his attacks. When Xemnas's reaction durability value reaches 0, he will flinch after every attack for 3.3 seconds. He fights with moves that are mainly seen in the final fight from the previous game, with the exception of the Spark Walls and the sphere teleports which are seen in the first fight. As soon as Xemnas reappears from the dark sphere, Lock-On to him and press {{button|dsy}} or {{button|square}} to guard against the ensuing Dual Blade or Flying Dual Blade, leaving him open to Sora's [[Counter Rush]]. Beware that Xemnas can still use Dual Blade again after a Counter Rush. The use of [[Sliding Sidewinder]] is also efficient at interrupting, staggering and repelling Xemnas. If he isn't using the sphere teleports and is instead idling, one can use [[Firaga Burst]] combined with either powerful Unison Attacks like [[Decussation]], or commands with extended combos like [[Ars Arcanum]], stunlocking Xemnas and dealing up to 3 or 4 HP bars of damage, especially when buffed with [[Spirit Roar]]. As with all bosses, a deck of alternating {{c|Balloon|ability}}- and [[Cure]]-type spells can also easily win the battle.

Xemnas's most lethal move surrounds Sora with Shots, where he should leap over them with [[High Jump]] and either use the [[Air Slide]]/Sonic Impact/Double Impact combo or perform Superglide. The position of the Shots circle and aiming will always match Sora's so it is advised to keep moving and land only when they're all gone. When Xemnas traps Sora in a cage of Spark Walls, simply [[High Jump]] over them and either Super Glide or repeat the Air Slide/Sonic Impact/Double Impact combo to avoid the ensuing barrage of Shots. One other trick is to climb the walls with [[Flowmotion]], jump while moving around to dodge the Shots and attack near Xemnas with [[Shock Dive]] to deal damage. In the case where he creates the four walls while near Sora, he can just Block the Shots and Counter Rush, interrupting and knocking Xemnas back. He may try to suddenly defend himself with a single Spark Wall from time to time to knock Sora back, but if possible he can either stay away from it to avoid getting interrupted or allow it to knock him backwards so that he can perform [[Payback Raid]], as Spark Wall deals no damage.

After half of his HP has been depleted, Xemnas resets the battlefield, and uses Building Throw. From Sora's starting position, it isn't required to move at all in case Xemnas throws one or two buildings, but in the case three are thrown, it will require Sora to dodge roll forwards after the nearest buiding falls in front of him. After all three sets of Building Throw have been sent, Sora gets sent into a gliding phase of the attack where he cannot move but can still use the Attack command (contrary to how it is displayed), and on the white building directed at him, he can trigger the [[Nightmare's End]] [[Reality Shift]].

If Nightmare's End succeeds, the arena will shift to its original form, and include a few chunks of buildings with long Flowmotion rails on top of them, with a passive Xemnas at its end who stays there for 30 seconds. The first hit will cause Xemnas to sigh and recover after around 4 seconds have passed, meaning that in the meantime, Sora should quickly unleash his most powerful commands until the Nobody recovers. Once he has recovered, Xemnas warps the battlefield back to its original state, and will increase the frequency and ferocity of his attacks, while not staggering from damage anymore (though his Dual Blade and Flying Dual Blade can still be interrupted by Blocks), making him more dangerous than he was before, and the tactic around using Sliding Sidewinder useful no more. 

If Nightmare's End isn't used, Sora will take damage from the building, but that can be avoided by triggering the Reality Shift and failing it on purpose. Afterwards, whether it fails or isn't used, the battlefield will shift back to its original form, but the ferocity and frequency of Xemnas's attacks, as well as his staggering will remain normal. For safety, failing to use Nightmare's End is recommended in case Sora is underleveled, at Level 1, or playing on Proud or Critical Modes.

In some cases, if Sora immediately kicks him with either Sonic Impact or Double Impact, Xemnas may use Building Throw again. He may also use this attack again if he is left undefeated for too long. In the rare case Sora gets defeated during the gliding phase because of the building but gets revived thanks to the [[Auto-Life]] status being active, he will essentially get soft-locked until his Drop Gauge gets depleted, with Xemnas staying intangible and immobile.

===''Kingdom Hearts III''===
[[File:Versus Ansem, Xemnas, and Young Xehanort KHIII.png|thumb|right|Young Xehanort, Ansem, and Xemnas, battling against Sora, Riku, and King Mickey in the Tower of Endings.]]
Xemnas is fought alongside [[Ansem, Seeker of Darkness]] and [[Young Xehanort]]. It is recommended to take him out last since he is the fastest and most aggressive out of them, making it difficult to land a combo. Xemnas will attack with his Ethereal Blades and hand-to-hand combat, employing a rapid slashing blade combo and swinging his Ethereal Blades in a helicopter-like manner before unleashing a burst of energy from his Ethereal Blades as well as spinning energy kicks, and can launch four energy balls and quickly move around while creating orbs that fire lasers. As his health decreases, Xemnas teleports more often to avoid attacks.

Each member will have a dark aura surrounding them, meaning they'll only attack Sora each time they disappear and reappear with a specific order of attacks. For Xemnas, Young Xehanort will release missiles of ice followed by Ansem's cage of dark claws that will launch Sora into the air and Xemnas using his rolling attack. Jump to avoid the dark cage and block the icicles and Xemnas's attack. Xemnas can release Ethereal lasers that can be blocked. Right as he launches the energy orbs, [[Airstep]] to him right away, as they cannot explode upon contact, to get a good combo. The end of his combos can be blocked and Sora can use [[Risk Dodge]]. When half of his health is down, or while the leader, his combos last longer and his finishing move will launch his victims into the air. During the cyclone sequence, each member will use a specific order of attacks. If Xemnas is the only one left, he'll first fire several Ethereal lasers that surround Sora, but can be difficult to block, then he'll do a normal combo followed by his rolling attack. He is immune to [[thunder]] magic, so use any other offensive spell to attack from a distance. Keeping Riku and Mickey alive is wise as they can do double and triple damage when attacking together. When they try to combo Sora's target, it would be wise to let them land their own. The Magic Carousel [[Attraction]] appears as well.

===''Kingdom Hearts III Re Mind''===
In addition to fighting alongside Ansem and Young Xehanort as in the base game, Xemnas also briefly fights alongside [[Saïx]] for the second phase of his battle. Here, the player plays as [[Roxas]], and has [[Lea]] and [[Xion]] as allies. Xemnas retains his attacks from the main fight, except the player can use the [[Thinking of You]] team attack.

When fought alongside Ansem and Young Xehanort, the fight is nearly identical except the [[Faith Volley]] and [[True End]] team attacks are available.

====Data Rematch====
[[File:Versus Xemnas's Recreated Data KHIIIRM.png|thumb|right|Xemnas's recreated data engaging in combat against Sora's data.]]
Xemnas's data is not only much stronger and with more HP but has also acquired several new attacks, making him much more deadly. He retains his old Ethereal Blades slashing combo and helicopter attack as well as his energy kick, but has gained new melee attacks: he can perform a leaping kick with both legs, which can be enhanced with a burst of energy, and also a straight kick as well as also gaining more sword combos. Xemnas has also gained the ability to use his old barrier ability, which can be broken with a single attack but damages Sora if he is thrust into it, and Twilight Thorns that do not damage but cannot be blocked, can interrupt reprisals and will launch Sora into the air, allowing Xemnas to easily catch Sora off-guard.

After a certain amount of Xemnas's health has been depleted, he will unleash his ultimate attack. He first surrounds the entire arena with darkness as Twilight Thorns begin to suddenly materialize out of nowhere, allowing Xemnas to force Sora into the air without Sora being able to react. Eventually, Xemnas will create thousands of Ethereal Blades and launch them as projectiles while also randomly attacking until the stage returns to normal; the red Ethereal Blades can be blocked, but the blue ones cannot so be sure to roll out of the way upon seeing one. Before the first barrage, Xemnas will use his quick three-hit combos before throwing Sora with his Twilight Thorns. Block immediately when he teleports. After his first barrage, he will go with his slower two-hit kick combos before throwing Sora. Sora should time his guards to block all his kicks. 

After the second salvo, Xemnas will immediately teleport for an unblockable X-shaped slash. Dodge Roll out of the way. Afterwards, Xemnas will use quick two-hit sword combos before throwing Sora, twice in succession, and follow with the unblockable X-shaped slash. The first barrage of Ethereal Blades are blockable, but the second barrage sends out blue Ethereal Blades after the first few red blades. The last barrage will shoot blue blades first and then shoot another few blue blades after a few following red blades. The last salvo will always leave Sora stunned afterward if he's not in a form or doesn't have Stun Protection and Xemnas will teleport in for the unblockable X-shaped slash, but Sora will recover before it comes. Dodge Roll out of the way and get in a combo on Xemnas.
