Demyx (Kingdom Hearts II)

From Atrocious Gameplay Wiki

Demyx is a minor antagonist and boss fought in Kingdom Hearts II. He initially attacks Sora and his allies in the Underworld as a mini-game boss, and then as a full-fledged boss in Hollow Bastion during the Battle of the 1000 Heartless. He can be re-fought at any point during the post-game as a data rematch in Kingdom Hearts II Final Mix.

He is often considered by casual players to be one of the worst bosses in the game. This is a byproduct of the fact that he is designed to punish hyper-aggressive play, which the game fails to discourage, and requires the player to understand openings and when to back off, which the game fails to encourage naturally. The difficulty spike is pretty noticeable, especially considering his placement in game progression is rather poorly thought out.

Why He Sucks

  1. In the beginning of the fight, he will summon water clones at you, and you must defeat them all, this wouldn't be the problem if it wasn't for the fact that if you don't defeat them all, its game over. This can be difficult due to the somewhat strict time limit.
    1. Said time limit jumps all over the place throughout the fight. Either you'll have plenty of time when he summons the clones, or you'll have a sadistically low amount of just 10 seconds.
    2. The amount of water clones can range from a decently small amount to a unbelievably high amount.
  2. After eliminating the first series of clones, Demyx begins to actually fight the player. A huge point of contention regarding this fight is that Demyx doesn't give free hits to the player. This isn't so much a bad design choice, but it's the first real instance of a boss requiring a defensive strategy on the player's part, which the game’s developers certainly doesn't put info on well to the player.
  3. In general, Demyx can be quite difficult to read, as he has a lot of fast, hard to predict attacks.
  4. After defeating him, you (As Sora) are thrown into three consecutive battles with some new heartless types, which, if you lose, will send you back to your battle Demyx, again.
  5. Despite his reputation among casual players, his Data Battle in Kingdom Hearts II: Final Mix is actually significantly worse. You can't use the water clones' Reaction Command unless they are almost dead, they have more health (attacking only with the Keyblade is a bad idea), and you can't strike the final blow unless you first defeat 99 water clones.

Redeeming Qualities

  1. Great music like most of the Organization XIII battles.
  2. Demyx isn't a terrible character, and is popular within the fanbase.
  3. If you're able to get his pattern down, the battle can be rather fun, letting you really experiment with the combat system.
  4. While FAR from perfectly executed, the core of the boss battle is interesting.


  1. Spam Fire near Demyx to kill the water clones whien they spawn, or while using the Wisdom form to home in on them.
  2. Bring many Ethers to this battle, since you'll use a lot of magic. It is also wise to map the Ethers to a shortcut to waste as little time as possible.
  3. In case you haven't leveled up wisdom form, it's good to go in with at least quick run unlocked, as it serves as a dodge against some of Demyx's attacks.
  4. Use Summons, such as Stitch or Genie, to give yourself an advantage.
  5. Don't be overly aggressive!! Demyx is designed to punish hyper aggressive play by countering with a fast leap from a water pillar directly around him. When you've hit him with one or two finishers, let him attack and punish him again.
  6. Overuse of Drive Forms will result in Anti-Sora appearing when attempting to use a Drive Form. Use Drives strategically to gain the upper hand. Just before this fight, you should have received Master Form which resets your chances of getting Anti-Form.
