How to Beat Vexen (Data Battle) in Kingdom Hearts II

Last Updated: February 16, 2023 References

Kingdom Hearts II is a game developed for PlayStation II consoles. This role playing game is set in a fantasy world where you get to choose your character, and embark on various quests. Vexen is originally a boss from Kingdom Hearts: Chain of Memories. He returns in Kingdom Hearts II as an optional boss. Although he's a relatively easy boss to beat, when he employs the aid of anti-Sora, things can get from easy to game over in a short period of time.

Learning Vexen's Attacks

1
Avoid his desperation attack. Vexen attacks you with floating icebergs; he then freezes you and attacks you with a stronger freezing spell.
- This can be avoided by spamming Reflega, then mashing ∆ when the Reaction Command appears.
2
Be careful of his Anti-Sora. Vexen collects Sora's data, then summons Anti-Sora to aid him in battle.
- Vexen has more attacks, but you'll only see these two (briefly).

Battling with Vexen

1
Attack Vexen as soon as the battle starts. This attack is only to propel yourself near Vexen and not to damage him.
2
Immediately cast Reflega as soon as you're near him. Vexen will attack you, and thanks to Reflega, you'll be able to reflect his damage back and destroy his shield.
3
Go into Final Form and start spamming Firaga at Vexen. Keep Vexen in the air during this time. Don't let him touch the ground or he'll recover his shield and possibly summon anti-Sora.
4
Get near Vexen and cast Reflega once his HP hits 3 bars. He'll try to use his desperation attack, but Reflega will be able to counter it. Make sure that you're standing near Vexen so his shield will be broken.
5
Continue spamming Firaga at Vexen until he dies. You should be able to finish the battle before your Final Form gauge runs out. If you do happen to revert back to normal before he dies, go into Limit Form and use Sonic Blade to finish him off.
