Game:Lexaeus

Lexaeus appears as a boss in Kingdom Hearts: Chain of Memories, Kingdom Hearts Re:Chain of Memories, and Kingdom Hearts II Final Mix.

Kingdom Hearts: Chain of Memories
Lexaeus's moves consist of him hitting the ground and causing earthquakes and Sleights. Try to dodge his sleight, which can hit Riku multiple times. First focus on card breaking Lexaeus's cards to turn into Dark Mode and use sleights to deal heavy damage. Use MM Miracles or the Oogie Boogie card if low on HP. Use sleights while he is charging the reload card so he can't card break Riku, unless he is low on DP, then use as many sleights as possible.

In Re:Chain of Memories, most of Lexaeus's attacks are similar. He repeatedly strikes the ground and jagged rocks shoot up, attempting to impale Riku. A new attack is when Lexaeus starts to glow yellow. His strength and speed are temporarily increased, he can do this twice.

His first card is usually an eight, as is Riku's, so he has an immediate opportunity for a card duel. Use all the card duel opportunities as possible, as they do a lot of damage (one and a half bars). Focus on breaking his cards and then go in for the combos, because he will smash Riku with his axe sword if he gets too close. After the first card break or combo, Lexaeus will use his Enemy Card, use Parasite Cage to negate the effect. If choosing to focus on attacking him, Riku will have to side step every time Lexaeus attacks, to avoid being stunned. Use Dodge Roll to pick up Mickey cards. Use the Enemy Cards Maleficent (to power up cards) and Oogie Boogie (if low on HP). Another option is to wait for his attacks and try to card duel him; after the card duel, recharge the deck and repeat.

Absent Silhouette
During this battle, Sora and Lexaeus have a power meter, which will increase as the battle rages on. Sora's power is permanently set to 100, but Lexaeus is capable of raising his freely up to 99999; at this level, the Silent Hero becomes nearly invincible, and Sora should try and avoid being hit at all costs. The higher the number, the more damage he will deal, and the properties of many of his attacks change.

During the fight, Lexaeus has four moves in his arsenal. In one, he leaps upwards with his Skysplitter to crush Sora, who can evade it with Dodge Roll and Reflect. In another, he hurls the Skysplitter three times, each time generating ripples of earth. The finisher has more power than the others and has a noticeable delay, so Sora can predict when to Dodge Roll. In the third attack, Lexaeus drags the Skysplitter on the ground to strike Sora. Sora should approach the Silent Hero and block with Guard or Reflect, giving the Keyblade wielder an opportunity to use the Mega-Impact Reaction Command. When this command is used, Sora siphons Lexaeus's power, increases it by 100, and strikes him, stripping the Silent Hero of his battle aura.

As the Silent Hero's health dwindles, he begins to increase his power level, repelling the party backwards, gaining a red aura, and altering his attacks. For instance, when he drags the Skysplitter on the ground to strike Sora, the attack has more range on higher levels. He can also charge at Sora, slam him onto one of the arena's pillars, and hurl his aura-infused Skysplitter. Alternately, he can grab Sora, throw him skyward, and slam him on the ground while pillars of earth erupt around the arena.

Lexaeus's ultimate attack involves him flying out of the party's attack range, laughing, before charging. Sora should guard the attack, but he must be ready to cast Reflect- the Silent Hero ends the attack by generating pillars of earth all around the arena.

Important Keychains to equip are Oblivion and Decisive Pumpkin, which are crucial if Sora wants to bring Lexaeus down quickly.

Data Rematch
The Data Rematch plays out nearly identical to the Absent Silhouette, but this time, he has more health and can generate more power.

To defeat the Data Replica, Sora should use the same strategy he used when taking on the original Absent Silhouette. However, while Sora has access to much more abilities than he had when taking down the Silhouette, Lexaeus is much stronger, and can employ countermeasures as well.
