Ansem, Seeker of Darkness is a boss in Kingdom Hearts, Kingdom Hearts Chain of Memories, Kingdom Hearts 3D: Dream Drop Distance, and Kingdom Hearts III. He is the Heartless of Terra-Xehanort, and leader of the Heartless.

In Kingdom Hearts III, Ansem is fought in the Keyblade Graveyard, initially alongside Xigbar and Dark Riku, although he retreats not long into the battle, and later fights alongside Xemnas and Young Xehanort. A data replica of him is also an optional boss in Kingdom Hearts III Re Mind.

Strategy

Kingdom Hearts

First battle

Ansem's first fight is a battle against Sora, Donald Duck, and Goofy at the End of the World's simulation of Destiny Islands. While his attacks are few, they are devastating.

During the fight, Ansem attacks with energy disks as he laughs, which can be blocked with Guard. He can also make the Dark Figure swipe at the party, or defend himself with it. However, with the right timing, Sora can just end up behind Ansem and deal damage to him. Special attacks like Ragnarok can pierce through the Dark Figure's defenses. When Sora is able to get past the Dark Figure and hit Ansem, he will have it turn around and swing at Sora from behind.

Ansem's most infamous attack is when he has the Dark Figure dash at Sora and swipe at him with a slight delay. He always yells, "Submit!" as he does this, so Dodge Roll at the right time to evade the Dark Figure, as Guard will not stop it. While the Dark Figure will always target Sora, there is a chance for Donald or Goofy to intercept the blow. If the Dark Figure's hit connects, it will possess its target, and Ansem will use a different attack where he surrounds himself with an energy barrier and tries to hit Sora with it, closing in.

If Sora is possessed by the Dark Figure, the Attack command will be occasionally replaced with "Freeze." Pressing it causes the Dark Figure to hold Sora in place for a brief moment leaving him open for Ansem's energy barrier to damage him; otherwise, the Dark Figure will damage Sora from within. While the Dark Figure will eventually be called back to Ansem's side, Sora can shorten the Dark Figure's hold on its target either with simple combos or with special attacks like Strike Raid.

Second battle

In the second battle against Ansem, Sora fights solo, so remember to heal with Curaga. Ansem will now use his Rush attack, in which he shoots back and forth across the arena with a shield over his front side. This inflicts heavy damage if it connects, so try to High Jump, Guard or cast Aeroga.

When Ansem says "My strength returns!", the Dark Figure will dive into the ground, creating dark pools underneath Sora which shoot out of the ground. During this time, Ansem is invincible and the attack must be avoided, either by dodging or Guarding. Failing to evade this attack can be highly damaging or even fatal, depending on the amount of HP Sora has at the time. The attack ends with the Dark Figure striking the ground, creating a shockwave.

Like in the last battle, Ansem still has a habit of siccing the Dark Figure on Sora. However, he will do this much more frequently than in the first battle. Ansem is especially vulnerable when he calls the Dark Figure to return to him, so unleash combos at this time for massive damage.

Kingdom Hearts Chain of Memories

First battle

This battle is rather straightforward, Riku should keep his combos going and card break Ansem's Dark Rush sleight to avoid damage. He can move up and down to avoid it as well.

Second battle

The second time Ansem is fought is during the final battle of Riku's Story. This time around, he brings a new sleight, Dark Shadow, wher he sends the Dark Figure into the floor, creating pools of darkness that the Dark Figure rises out of, fist raised, that can deal chained up damage. It's best to use 0 cards to break Dark Shadow when he is preparing it, but it can be avoided by dodging with the right timing. There is one unorthodox strategy that involves losing all of Riku's cards (from Sleights) except one 0 card. If he gets left with one 0 card, immediately reload after (because Riku has instant reload, unlike Sora) and continue a combo. This works because the zero will always break Ansem's next card and if he breaks Riku's, reloading will give Riku a zero card.

Ansem's Sleights tend to be reserved for later, and he initially just bothers with single card attacks. Once he loses 1.5-2 bars of HP he will start using his Sleights more regularly and attempt to break the player's. He will always start using his own card to hide his Sleight's value, but the Parasite Cage card can dispel this. A good idea is to use simple Sleights at the beginning to hit Ansem quick and for high damage all the while accumulating DP. Following this the player should have Dark Mode and Ansem will start using his own Sleights so having a few 0 cards nearby is advisable. Otherwise assaulting Ansem with Sleights like Dark Break or Dark Aura is helpful, esspecially the latter as it can prevent Ansem from using his cards during the assault, although special care should be placed during the execution as he can break it with a 0 card of his own so it is advisable (for the entire battle) to use these Sleights instantly after Ansem attempts to use his own cards to Card Break him, thus leaving him vulnerable to the attacks. The Jafar-Genie Card can be used to prevent card breaks, but only if Riku uses cards one after another.

Kingdom Hearts Re:Chain of Memories

First battle

Riku's first fight with Ansem is meant to act as a tutorial on basic combat, and is very short.

Ansem will also use the "Shock Slash" technique, which can be easily dodged. The tutorial has been narrowed down to focus on the new Rapid Break and the new Duel System mechanics, and ends as soon as Riku successfully performs them.

Second battle

Ansem, Seeker of Darkness fighting against Riku for the final time.

The second fight with Ansem is more or less the same as in the original game, with the addition of "Shock Slash", and the finisher shockwave of "Dark Shadow".

Start with the Maleficent Dragon Enemy Card and attack Ansem with combos. Make a Card Break every time to gain Dark Points and after Riku transform into Dark Mode, use the Jafar-Genie enemy card and use Sleights like Dark Break, Dark Firaga and Dark Aura to inflict heavy damage. After taking three (or more) King Mickey Friend Cards, use the MM Miracle Lv. 2 or MM Miracle Lv. 3 sleights to recover HP, reload cards, and damage Ansem. Break Ansem's Sleights every time and continue the attacks. If Riku transforms into his normal form again, keep attacking and use the Item Card Hi-Potion to reload his Attack Cards. Win the Card Duels for heavy damage to Ansem. Never attack Ansem with the Dark Figure in front of him, and instead use that time to reload Riku's cards or use MM Miracle Lv. 3 to recover cards and HP. Use the Oogie Boogie Enemy Card to help keep up Riku's HP in the battle. Watch out for certain Sleights used by Ansem, as some can deal heavy damage to Riku. With a high level, deft dodging, and good use of the Enemy Cards, Ansem should fall eventually.

Kingdom Hearts 3D: Dream Drop Distance

First form

Ansem, Seeker of Darkness's first form fighting against Riku.

The battle starts with both parties in midair in Darkness's Call. As Riku is fully in midair, his Dream Eaters won't be active during this phase of the fight, and won't be able to give him support through spells like Cure commands, Haste, or Spirit Roar. Due to the absence of the latter, his damage will be very limited if he is underleveled, and nearly null at level 1.

Ansem's Shock Slash has been upgraded and now homes in on Riku, and he has a habit of chaining them together for combos. Riku may block it, but as he is floating, only Dark Barrier can allow him to. Whenever his attacks land a hit on Riku, there's a chance, depending on the difficulty, that Ansem responds with a taunt, leaving him vulnerable during a few seconds. His Rush is slightly different from other versions of the attack, and must be dodged. Riku can either just fly sideways when Ansem is about to charge at him or Air Slide either out of the way at each charge, or straight at him, taking advantage of its invincibility frames, in order to follow with Sonic Impact and Sliding Crescent once the enemy's attack is over.

Ansem cannot aim at Riku once he uses Vanish, so he may use it to his advantage and stay in a blind spot while attacking him from the distance. If Riku deals enough consecutive damage, the Reality Shift marker will appear and he can use Mirage Split to damage Ansem and make a platform appear.

Now the battle is on a platform on Darkness's Call. Riku's Dream Eaters are back, and he may benefit from their active support. If he uses Vanish, or gets revived thanks to Auto-Life, Ansem will aim at the first of the two Dream Eaters of Riku's party instead. The Dark Figure now serves as a lock-on target for the time it protects Ansem, and despite it having its own HP bar in the meantime, it cannot be depleted. He remains vulnerable to commands that circumvent the Dark Figure's protection like Balloon or Triple Plasma during that time, and Flowmotion may be used on the Dark Figure the same way as on wall, interrupting the protection, where Riku can attack Ansem with a Shock Dive attack.

Once enough time has passed, he starts to use his old Racing Shockwave which now has the Dark Figure charge the attack before unleashing the powerful blasts that cannot be blocked. He will try to stay outside of the arena's bounds each time he is about to attack, making short-ranged commands almost useless. Each Racing Shockwave destroys a layer of the platform Riku stands on, but he may interrupt the process for a while if he manages to make Ansem flinch. Once Racing Shockwave has been used three times, the platform completely disappears, along with Riku's dream eaters, and the battle goes back to its initial state, with Ansem's Rush and Shock Slash and Riku's floating combat abilities. Until Ansem uses Rush at least once, he will remain hard to hit due to the fact he stayed outside of the arena's bounds while using Racing Shockwave.

On the 3DS version only, it was possible to stunlock Ansem by repeatedly using the Attack command right after a successful Reality Shift until his HP reaches 1, where then normally attacking him would finish him off. This strategy would fail if Ansem would immediatly get the Dark Figure to protect himself.

The fight itself is relatively straightforward and the same strategies from before can defeat the Heartless once more.

Technique		Element	Status	Power	Block?
Shock Slash (衝撃斬, Shōgekizan)		Physical	—	0.2 x6	△
		The Dark Figure hurls razor-thin discs of energy homing in on Riku.
Rush (突進, Tosshin)		None	—	1.2 x5	X
		Surrounds himself in a dark aura, then charges at Riku.
		Used during normal combat only.
Dark Blow (ダークブロウ, Dāku Burou)		Physical	—	1.0	O
		The Dark Figure attacks with a dark-charged fist.
		Used with the Reality Shift platform on. While Ansem moves towards Riku to be within range, Ansem won't attack if Riku is airborne and will instead keep moving around his position and attack whenever he lands.
Sledgehammer (スレッジハンマー, Suredjihanmā)		Physical	—	1.5	O
		The Dark Figure attacks with dark-charged downwards overhands that can hit Riku even if airborne, no matter the height.
		Used with the Reality Shift platform on.
Racing Shockwave (地走り衝撃波, Jibashiri Shōgekiha)		None	—	1.0 per hit	X
		The Dark Figure charges and hurls powerful shockwaves at Riku along the ground. Ansem usually moves out of the arena before preparing the attack.
		Used with the Reality Shift platform on, after enough time has passed. Each shockwave destroys one layer of the Reality Shift platform. Once three are destroyed, the platform disappears.
With the Reality Shift platforms on, the Dark Figure may protect Ansem from most attacks, with the exception of commands that bypass its protection. When it protects him, the Dark Figure serves as a target substitute, has a HP bar that cannot be depleted, and acts as a wall on which Flowmotion can be used.
Guard/Block: △ = Can be blocked; O = Can be blocked and interrupted (melee) or deflected back (projectile); X = Cannot be blocked.

Second form

Ansem, Seeker of Darkness's second form fighting against Riku.

Ansem merges with the Dark Figure as he transports both himself and Riku to the Darkest End area. Ansem is now sealed inside a massive organic sphere with his Dark Figure attached to the top. Long-ranged commands are recommended in the case Ansem uses Dark Wave to back away, and as he will never use his Dark Rush attack if Riku is at a minimum of distance. Once More can make the use of Firaga Burst safe during potentially lethal mult-hit blows. The repetitive use of Balloonra can also deal a lot of damage to Ansem as well. Just like the previous fight, Ansem may respond with a taunt once his attacks succeed. When Ansem starts Dark Matter, Riku can use Firaga Burst (where the big fireball stays where it is) and once at the back, Ice Barrage to deal extra damage, but he must Lock-On for the ice command. Having Dark Roll equipped will help him move faster through the arena.

Once Riku is at the back of the arena, he can use Dark Splicer, Dark Aura or Zantetsuken, or the Ghost Drive Dual Style, when he reaches the end of the pathway to warp right up to Ansem and deal damage. This is a risky tactic, as Riku can easily be captured by the Dark Web into the spheres of darkness, or get punched by Dark Rush.

In other cases, Riku needs to go back to Ansem by either rolling forwards, or using the walls on the sides. The Dark Laser attack can be deadly if Ansem uses it repeatedly. In order to avoid it, Riku should dodge aside the moment the Dark Figure's shots merge into the spheres. The Chaos Firaga attack can be dodged by rolling forward, but beware of Riku's Dream Eaters when they get afflicted by Confuse, as it makes them backstab him. If Riku gets any closer, Ansem uses the Dark Webs that will drag Riku into the spheres. Since they can't get Riku while in midair, he can use Flowmotion to evade this by staying airborne, as they last for quite a while; or use Firaga Burst with Doubleflight to stay in the air so he won't be able to drag Riku in. Then use Flowmotion with Sonic Impact, if possible, to go back to the walls. Beware that if Riku hits the ground after falling, he might not be able to block immediatly and will be at the mercy of said Dark Webs. If Dark Barrier is equipped, Riku can also repeatedly use it to block the attack when close enough to Ansem, and use Counter Aura at the last moment each time. If Riku is too close though, Ansem might want to punch him using Dark Rush. Riku shouldn't stay on the sides of the arena and stay instead in the middle, as once Dark Matter is over, Riku may get caught off-guard and grabbed by the incoming moving spheres if he's in their way. Afterwards, press LR or L3 to return the Spirits back to Riku's position (two times if LR unlocks the target) so they will be able to help, but only once Dark Matter is over, as they may get caught by the Dark Webs, become unable to help, and sent backwards. In the case Riku gets caught by the Dark Webs or the spheres themselves, he will get immobilized in the sphere and struck by Planet Buster, but Planet Buster isn't a deadly attack will put an end to Dark Matter once it is over. Willingly letting Riku get caught by the Dark Web to skip Dark Matter is a viable option if a Cure command is available for him to use afterwards.

If Riku deals a lot of consecutive damage, the Mirage Split Reality Shift prompt can eventually appear. Dealing huge damage when close and stunning Ansem for a moment. Whenever he rallies, he will tend to use Dark Galaxy immediatly. In the 3DS version only, if Riku pounds him right away with the Attack command, Ansem will get stunlocked and Riku may unleash the same Attack combo over and over until Ansem's HP reaches 1. After some time, while hitting him again and again, the Reality Shift prompt can reappear, so Riku will be able to finish him off with it.

As soon as he has lost half of his HP (or two thirds on Critical Mode), Ansem starts using Dark Galaxy. It is potentially his most lethal move as the torrents of darkness appear randomly across the arena and may also hit Riku multiple times. One way to deal with it is to block the torrents and to keep dodge rolling backwards. Once Ansem finishes this part of the attack, he sends Riku flying across the pathway again. The black spheres can easily defeat Riku if he gets hit even once as the others may follow up for chained up damage. He must then either carefully dodge or block these. Riku shouldn't try sliding towards the wall as Flowmotion cannot be activated on them during this attack, but he can still use dodge roll along them with no fear of activating it and return to Ansem rapidly. However it isn't recommended to permanently dodge roll, because he may get hit if the timing is wrong, meaning he must dodge roll only when a sphere gets near him while keeping running back. One other alternative, where he should have Second Chance/Once More equipped in order to survive, is where he can use Dark Splicer just as the ball bombs reach him to go near Ansem and deal some damage, while staying at his position. Dark Splicer lasts long enough until the end of Dark Galaxy; therefore, there shouldn't be any risks for Riku to be knocked back, but he should immediately heal after this. Whenever Riku returns to Ansem, press LR or L3 to make the Spirits come back to him. After this, just repeat the cycle of pounding Ansem and running back to him and he'll go down.

Kingdom Hearts III

Young Xehanort, Ansem, and Xemnas, battling against Sora, Riku, and King Mickey in the Tower of Endings.

Ansem is first fought when he fights Riku and Sora along with Xigbar and Dark Riku, but he leaves the battle after 30 seconds and is finally fought for real alongside Xemnas and Young Xehanort at the end of the Keyblade Graveyard.

Ansem's attacks include him creating violet spheres of light around Sora that launch lasers at him, surrounding himself in those spheres to generate a damaging barrier as he rushes to attack Sora, creating multiple dark crests that explode upon contact, spawning a dark circle that follows Sora and eventually transforms into a cage of dark claws, and his deadliest has Ansem exert red energy around him which pulls in and knocks back Sora before he unleashes tendrils of darkness that deal heavy damage; however if timed correctly, one can use Aerial Recovery and Payback Strike, as the knockbacks before the blast deal no damage and it's possible to Glide away before getting trapped. During his attacks with the spheres, he cannot be flinched when hit. When he creates dark mines, the best way to clear them is to use Thunder magic. Sora can also use the explosions to trigger a reprisal by standing near the mines and blocking the explosions. This can work regardless of whether of not flash step is equipped.

Each member will have a dark aura whenever they disappear and reappear, meaning that Sora will be their only target. Each time they reappear, they will use a specific attack with the one with the aura appearing last. For Ansem, Young Xehanort will use his whip-snaring attack followed by Xemnas launching energy balls and Ansem using his shockwave last. To avoid this, Sora should Dodge Roll or jump to avoid Young Xehanort's attack, block Xemnas's energy balls, and if Ansem hits Sora, time Aerial Recovery and then Payback Strike. Each time a member is defeated or if all three disappear after attacking with the dark aura, the cyclone sequence will repeat itself with each member using a specific attack. If Young Xehanort is defeated first, Ansem will launch spheres of light that will extend into beams, then will release the cage of claws which will launch Sora into the air followed by Xemnas's rolling attack. First jump to avoid the cage and block all the beams and finally Xemnas. If Xemnas falls first, Young Xehanort will launch missiles of ice that will freeze Sora, followed by Ansem's shockwave attack. If Ansem's the only one left, he'll release the spheres like with Xemnas and use his shockwave attack. Sora can either block the beams and use Payback Strike or Dodge Roll the beams and Glide away, but the timing of the spheres can be a little tricky to dodge.

Technique		Element	Status	Power	Block?	Repel LV
Annihilation (アナイアレイション, Anaiareishon)		Physical	—	1.5 per hit	△	2
		Master Xehanort summons a storm of Keyblades that temporarily removes Riku and Mickey and surrounds the battlefield. Bundles of Keyblades will fly around Sora one-by-one (the last four bundles directly target him). Afterward, remaining enemies attack in succession; techniques used depend on those remaining.
Leader Cooperation (リーダー連携, Rīdā Renkei) has one enemy designated as the leader. The non-leaders attack first, then the leader after them; the order depends on those remaining. When Leader Cooperation is used, one enemy is designated the "leader"; the leader is surrounded by an aura and targets Sora until the next use of Leader Cooperation. The initial leader is the one with the lowest maximum HP in terms of percentage, and they rotate between each other. When only one enemy remains, they automatically become the leader and use of Leader Cooperation is discontinued.

Data Rematch

Ansem, Seeker of Darkness's recreated data engaging in combat against Sora's data.

Ansem's data rematch pits Sora against a much stronger Ansem with multiple new abilities.

Ansem starts by summoning several laser orbs that float around Sora, then he summons a line of dark crests, and he'll follow up with firing sets of four projectiles and two projectiles shortly after that, four times. Once the first orbs start glowing, guard to block the lasers, then cast Thundaga to stun Ansem, airstep to him and attack to skip the projectiles. Additionally, wait until he fires the projectiles and airstep to him to attack. However, the timing is more strict this time as he might fire the second set, or the first set might still hit Sora. When his HP gets lower, he'll fire the projectiles immediately upon summoning the crests, giving no time to stun him with Thundaga.

Ansem frequently summons a circle of lasers around himself and chases Sora. This attack can easily be dodged or blocked consecutively. You can use a reprisal near the end to deal minor damage to Ansem, but don't follow up with a combo, as he'll immediately start the next attack.

Next, Ansem summons a shadow that follows Sora underneath him, along with a circle of crests around Sora. Wait for the shadow to expand, and dodge to avoid the dark claws. Wait for the crests to move before dodging those as they close in. After this, Ansem is open for a combo, so attack, using airstep if necessary.

Ansem retains his old Dark Rush ability. He will rush Sora twice, then charge up and perform a more powerful dash. Block the first two dashes, then quickly airstep and immediately block without attacking. The third rush breaks Sora's guard, so use Risk Dodge to counter before landing a combo.

After losing some HP, Ansem will perform his ultimate move, where he covers the entire arena in darkness and summons two giant orbs of darkness. The orbs will fire shots that will inflict the Burn, Freeze, Cloud or Sneeze status. Ansem can also trap Sora with the orbs, dealing heavy damage and inflicting the Cloud status effect. When activating his ultimate move, Ansem will first move sideways in front of Sora. Once one of the orbs starts shaking, guard to block the shots. After blocking four times, airstep to Ansem and attack him. Next, he'll warp further away and the orbs will be at your side. Wait for one of them to move away slightly before blocking. After doing this three times, Ansem will try to trap Sora with the orbs. Dodge Roll forwards to dodge the orbs, then airstep to Ansem to counter.

After using his ultimate move, Ansem will have some new attacks. One involves him standing in the center of the arena, glowing red, and pulling Sora in. During this move, two sets of laser orbs will appear to damage Sora. Dodge the lasers instead of blocking to avoid getting sucked in, and keep dodging to avoid Ansem unleashing a shock wave. Afterwards, he'll be open to attack, so airstep to him and strike.

Ansem will have a different version of the laser orb attack after his ultimate move. He'll start by summoning a wall of lasers in front of himself, summoning lines of dark crests, and summoning the laser orbs. Block the lasers and use Counter Kick after the final laser to dash through another wall of lasers and attack Ansem.

Once his HP gets low, he'll perform a variation of his ultimate move. Once again, he'll cover the arena in darkness and summons the giant orbs. However, once this starts, quickly dodge away as he'll try to trap Sora right away. After this, he'll place the orbs behind one another. After a short pause, the front orb will fire a barrage of shots that can inflict Sneeze before shooting itself forwards to trap Sora. Guard repeatedly to block the shots, then Dodge Roll through the orb. Repeat this with the second orb, and after Dodge Rolling though that, airstep to Ansem and attack. Next, he'll stand in the center, firing striped orb projectiles. These can't be blocked, so dodge them. He'll continue with the other attack afterwards, so block, dodge and attack until he falls.

If Sora is having trouble blocking and dodging his ultimate move, try to equip armor to protect against the status effects it causes.
