In Re:Chain of Memories, Zexion battle Riku when they clash after Marluxia's destruction.
While Zexion isn't a boss in Chain of Memories, his boss cutscenes from Re:Chain of Memories occur after the battle with Darkside.
In Kingdom Hearts II Final Mix, Zexion appeared before Sora as both an Absent Silhouette and a Data Replica. Both his Absent Silhouette and Replica Data are fought at the 3rd Basement facsimile of Destiny Islands. The portal to the Absent Silhouette battle appears in the Cave of the Dead's Inner Chamber after Sora escapes Hades.
Kingdom Hearts Re:Chain of Memories
- Catastrophe - Zexion and his body clones create a sphere of energy in the center of the battlefield, rotating around and shooting beams of energy at it. The sphere will then burst into a wave of unavoidable light energy.
- Cyclone Snatch - Zexion creates a damaging black vortex in the center of battlefield that draws Riku in and steals two Soul Eater cards each time he gets close enough to it.
- Dark Punisher - Zexion grabs Riku, draining his HP.
- Dark Revenge - Any of Zexion's surviving body clones rush at Riku, slashing him with their replicated Soul Eaters. The true Zexion then performs a downward slam attack.
- Dummy Card - Riku takes damage and stuns himself.
- Magnet Snatch - Zexion creates a sphere of Magnet energy in his Book of Retribution, sending it at Riku and stealing three Soul Eater cards.
- Zexion telekinetically throws the Book of Retribution in Riku's direction.
- Zexion summons three clones of himself.
The battle against Zexion can be quite an annoyance and difficult to overcome. Luckily, Riku will remain in Dark Mode for the entirety of the battle, granting the player an increase of strength and speed, as well as the ability to use Sleights. Despite this, it is recommended that Riku have a relatively high AP level, ensuring he deals as much damage as possible through any means of offense.
Zexion's main strategy is to continuously steal Riku's cards in order to prepare for his more threatening techniques, something that is done mainly through telekinetically throwing the Book of Retribution in Riku's direction. If this attack hits, Riku will lose three cards which cannot be reloaded while in Zexion's possession. This tactic can be successfully dodged by using Dark Mode's "Quick Run".
Zexion's one last method of swiping Riku's cards and his only available Sleight in early stages of the battle is Cyclone Snatch. During the execution of this Sleight, Zexion will create a black vortex in the center of the battlefield. This vortex will draw Riku in so long as it remains, dealing slight damage when he touches it and stealing two cards per hit. Cyclone Snatch can be avoided, however, by continuously using "Quick Run" towards the edge of the battlefield until the attack ends.
When the boss has collected enough cards, three copies of the Book of Retribution will appear in the corners of the battlefield, glowing with a mysterious aura. Zexion's deck will convert from his all-magic one to a deck comprised of Riku's stolen Soul Eater Cards and three copies of the boss will appear, each with a false Soul Eater in hand. When Zexion uses a Soul Eater card, his clones will rush at Riku, slashing him, the combo ending with a downward slam from Zexion himself. Zexion also will have access to two very powerful Sleights, Dark Punisher and Catastrophe.
During Dark Punisher's execution, Zexion will grab Riku from behind, slowly draining his HP. Only a Card Break will free Riku from the boss's grasp. Catastrophe is far more deadly. During its execution, Zexion and his replicas rotate around the area, while Zexion summons a sphere of light energy in the center of the battlefield, shooting a laser beam at it while any remaining clones do the same. Again, only Card Breaks will allow Riku to escape.
The execution of these powerful melee attacks and Sleights will continue so long as the four Lexicons remain on the field. Thus they must all be destroyed, something done through careful utilization of aerial attacks or even an Inverse Burst Sleight made possible through a King Mickey Friend Card. Not only will destroying a Book of Retribution cause a Zexion clone to vanish (note that the number of remaining clones will effect the number of hits landed in Zexion's standard combo), but it will also relinquish EXP.
Successfully destroying all four Book of Retribution copies will cause all the Soul Eater cards that Zexion stole to reappear on the battlefield and picking them up causes them to return to Riku's deck for normal use. His most powerful techniques no longer available, Zexion will then revert to his card-stealing strategy.
The player must take extreme caution once the Book of Retribution copies are first destroyed, however, as Zexion may place a decoy Soul Eater card (recognized by its unique coloration) amongst the fallen cards he had previously stolen. Should the player use this card unwittingly, Riku will take damage and be stunned for a time, opening him up for more damage and allowing Zexion to easily steal more cards.
In terms of recommended methods of defeating Zexion, the player should utilize Card Duels whenever possible. Dark Barrage can be especially powerful when one has a high AP level, and the fact that it can hit multiple targets will allow Riku to destroy Zexion's Book of Retribution copies, causing EXP to drop as a result. Zexion's attacks should be Card Broken whenever possible, as most will be unavoidable if this does not occur.
Sleights should also be used to the player's advantage, even though Riku's poorly composed deck will only allow the usage of Dark Break and Dark Firaga, a high AP level greatly increasing the damage done by these abilities, as well. Despite the great advantage Sleights will provide HP-wise, they should not be abused, as continued use of Sleights to deal heavy damage or Card Break an attack will quickly reduce Riku's number of usable cards from the beginning amount of 23 to one or two, this negative side-effect only worsened by Zexion's card-stealing abilities.
Being left with only low-numbered cards will greatly hinder the player once Zexion summons his clones, as he will use higher card values than usual during this time, making destroying the Book of Retribution copies a difficult task, the lack of high valued cards in Riku's deck possibly making it impossible to stop Zexion's Sleights. Any King Mickey cards should be saved, as they will be useful for replenishing Riku's HP if it ever hits the Alarm Zone.
If Zexion ever utilizes his Enemy Card, one that grants him the Confu-Strike ability, the player must use extreme caution, as any attack utilized by the boss will have a chance of granting Riku the Confused status effect. While confused, Riku's controls will be reversed. This can be an extreme hindrance when it comes to dodging an attack. If Riku ever needs extra support mid-battle, an Enemy Card such as Jafar, Maleficent, or Oogie Boogie may be used. Beat him up a little to elicit a "I'm beginning to feel it," in a weak voice.
Kingdom Hearts II Final Mix
- Zexion's Absent Silhouette will attempt to trap Sora and friends within the Book of Retribution.
In Kingdom Hearts II Final Mix, the absence of cards completely changes Zexion's attack style. At the start of the battle, Zexion's Absent Silhouette will attempt to trap Sora and friends within the Book of Retribution. In order for any member of the trio to be trapped, they must stand within the path of the glowing symbol Zexion summons before him. If Donald or Goofy is trapped, they will alert the player by shouting Sora's name, needing to be released from the Book of Retribution through physical combos. Once the Book of Retribution is destroyed, the character it held captive will be freed. If Sora himself is captured, a whole new set of problems are presented.
Once Sora is captured, he will be sent to a parallel dimension, one contained within the Book of Retribution. Here, Sora will be bombarded by copies of the Lexicon, having to find Zexion, who has concealed himself within the true Lexicon. Once the Book of Retribution hiding Zexion has been located, its HP bar must be depleted and the Dispel Reaction Command can be used to return Sora to the real world. In the mean time, Sora may be able to utilize a unique, non-offensive Reaction Command. This will allow him to obtain much-needed Drive Orbs and HP Orbs mid-battle via the command menu.
Abilities such as Donald's Comet Limit will prevent Sora from taking damage from the Lexicons as they rain down on him, while also dealing damage to Zexion's Absent Silhouette in the Book of Retribution. Limit Form is a recommended Drive Form for use when within the pocket dimension, as its HP-restoring attacks will also deal great damage and not cause Donald or Goofy to disappear. Once Dispel is used and Sora is returned to the real world alongside Donald and Goofy, proceed to bombard Zexion with ground and aerial combos alike.
Once the boss's HP begins to dwindle, he will capture Sora and send him to a different area of the pocket dimension. Three circles of light, two red and one blue, will then appear on the ground. The colors of the circles will then proceed to alternate, Sora having to land on the circle that remains blue within the time limit. Success will surround Sora, Donald, and Goofy in a protective barrier, allowing them to attack the concealed Zexion. Failure to do so will cause Sora and the party to be bombarded by meteors.
A long-lasting Limit such as Duck Flare or Comet can be used to prevent damage, but Sora can also rely on the Once More or Second Chance abilities if he has them equipped and then utilize Cure or a Potion when the attack ends. Sora, Donald, and Goofy will then be transported back to the first area of the pocket dimension, Zexion's Absent Silhouette again needing to be located and attacked so that the Dispel Reaction Command may be used. The boss can then be bombarded by physical attacks or spells such as Fire and Thunder until defeat, Zexion's Absent Silhouette relinquishing a Book of Shadows Recipe as a reward for having been conquered.
- Zexion's Absent Silhouette will attempt to trap Sora and friends within the Book of Retribution.
The battle against Zexion's Data Replica will flow quite similarly to the battle against his Absent Silhouette. The only differences will be the amount of HP the boss has and the pattern in which he uses his attacks. In short and aside from these minor differences, the battle against this Data Replica should not be difficult.
All the player must do is recall the strategy used in the Absent Silhouette battle and use the Dispel Reaction Command when trapped within the Book of Retribution. Sora also should be of a relatively high level, using spells such as Curaga and Reflega, as well as Drive Forms and a powerful Keyblade such as the Ultima Weapon. Defeat Zexion's Data Replica, and a Lost Illusion will be obtained.
