Game:Ansem, Seeker of Darkness

Ansem, Seeker of Darkness is a boss in Kingdom Hearts and Kingdom Hearts: Chain of Memories. He is the Heartless of Xehanort, and leader of the Heartless.

1st Battle
In the first battle, Ansem fights Sora, Donald, and Goofy fight in the End of the World, alongside his "guardian". He takes it easier on the party at first, so fight ferociously but cautiously. Use aerial Keyblade combos, since Ansem floats and attack magic isn't very effective.

At the beginning of the battle, Ansem will make few attacks, which should make attack combos easy to perform. When he does attack, he shoots energy disks resembling Strike Raid, uses his guardian to attack physically, and sends his guardian to attach itself to Sora while he creates an energy shield around himself that deals damage. Usually, this can be avoided, as Ansem yells "Submit!" before doing this, so Sora can Superglide out of harm's way. However, in the event when the guardian does manage to attach itself to Sora, a "?" will appear over Sora's head, and the Attack command will occasionally change to Freeze. Selecting it will cause the guardian to hold Sora in place while Ansem does damage to him. It is best to physically attack Ansem while within reach, and heal with Curaga periodically, because the guardian will gradually reduce Sora's HP. Alternatively, you may stay out of Ansem's reach, and then hit the Freeze command - Sora will just be held in place while Ansem will be too far away to deal any damage to him. Also, this prevents Sora from losing any HP. Be sure to attack Ansem while the guardian is attached to Sora, as this makes the attachment shorter; it's also a good idea to use special attacks such as Ragnarok and Ars Arcanum to end the attachment and battle sooner.

Once the battle is over, approach to the crater he has created. However, be sure that Sora has plenty of healing items equipped.

2nd Battle
In the second battle against Ansem, Sora fights solo, so remember to heal with Curaga periodically, since Donald won't be around to heal you! Ansem uses two new attacks: one resembles Riku's Dark Aura attack, in which he shoots back and forth across the arena with a shield over his frontside. This can be blocked using Guard or an Aero spell. The second attack is shown by Ansem starting to glow, and he will say the he'll show you his power. This attack has him sending his guardian into the ground, creating dark pools underneath Sora which, the guardian shoots out of with its fist raised. Ansem will show the guardian's return by saying "My strength returns!" During this time, Ansem is invincible, and the attack must be avoided, either by running, Supergliding, or by using Dodge Roll. Failing to evade this attack can be highly damaging, or even fatal, depending on the amount of HP Sora has at the time. Like in the last battle, Ansem has his guardian attach itself to Sora. However, he will do this much more frequently than in the first battle. As in the first battle, stay out of harm's way by Supergliding. However, if Sora is attached to, do not try to attack while the Freeze option is available. If you do so, Ansem and his guardian will attack you together for massive damage. Attacking while attached to with the Keyblade will be deflected by a force field as well. To break the force field, use Ragnarok; this is the best way to attack while the guardian is attached to Sora.

With constant use of Curaga and MP-restorative items, Sora can easily survive this battle. Ansem is especially vulnerable when he calls his guardian to return to him, so unleash Keyblade combos at this time for massive damage. The third and final fight with Ansem involves the World of Chaos--see World of Chaos for information on the battle.

Kingdom Hearts: Chain of Memories
Riku fights Ansem twice in this game. The first time, Ansem shoots out a bolt of lightning that travels horizontally. This can avoided by jumping or dodging. Ansem's only other attack during this first fight is a weak physical attack using guardian. The second time Ansem is fought is during the Final Battle of Riku's Story. This time around, Ansem brings into play some of his attacks from the first game, such as the Sleights Dark Rush (where he zooms back and forth across the arena) and Dark Shadow (when he sends his guardian into the floor, creating pools of darkness that the guardian rises out of, fist raised). It's best to use zero cards to break Dark Rush (Although it can be jumped over with perfect timing in CoM), but Dark Shadow can be avoided easily by dodging.

Kingdom Hearts Re: Chain of Memories
Note: In Re:Chain of Memories, note that Ansem still uses his Strike Raid-like attack during the final battle - Riku can either break this attack or dodge it.

The first fight with Ansem in the game is, in fact, an event battle, meant to get you used to the new mechanics.

Start the fight with the Maleficent Dragon Enemy Card and attack Ansem with combos, make a Card Break every time to gain Dark Points, after Riku transform into Dark Mode, use the Jafar-Genie Enemy Card and use the Sleights like Dark Break, Dark Firaga and Dark Aura for heavy damage in Ansem.

After take three (or more) King Mickey Friend Cards, use the '''MM Miracle Lv. 2 or MM Miracle Lv. 3''' to recover HP, reload cards and damage to Ansem. Break the Ansem Sleights everytime and continue the attacks. If Riku transforms into his normal form again, keep attacking and use the Item Card Hi-Potion to reload your Attack Cards. Win the Card Duels for heavy damage in Ansem.

Never attack Ansem with his Guardian in its front (or your Attack Card is break), only use that time to reload your cards or use '''MM Milacle Lv. 3''' to recovery cards and HP. Use the Oogie Boogie Enemy Card to the regen effect can help you in the battle. Watch out with certains Sleights of Ansem, some can make heavy damage to Riku. With high level, good status and good use of the Enemy Cards, Ansem is not a great problem.
