Game:Lock, Shock, and Barrel

Lock, Shock, and Barrel are boss characters who appear in Kingdom Hearts, Kingdom Hearts II, and Kingdom Hearts 358/2 Days. They are children from Halloween Town. Originally from Tim Burton's "The Nightmare Before Christmas", they carry out many roles in the games. In Kingdom Hearts, they assist Oogie Boogie by stealing Jack's experimental heart. In Kingdom Hearts II they wreak havoc in Christmas Town. During the boss battle all three of them appear together unlike other boss fights where Sora battles a single, individual boss. Because of this a lot of havoc is created during the battle.

Kingdom Hearts
The trio is fairly easy to defeat; begin by defeating Lock. He will leap very high to avoid Sora. Then focus on Shock; be careful when she goes into her spinning attack. Jump, dodge, or guard to get out of the way then hit her with Fire or Blizzard magic to slow her down. When Lock and Shock are defeated, begin attacking Barrel, as he has the most HP it may take a few extra hits. Barrel's special move is a cannonball sprint; it is possible to stop him but good timing is crucial.

It is a good idea to have a Potion or two at the ready, or Cure magic as shortcuts as having multiple enemies can make the Guard ability more or less worthless. Make sure to defeat them in that order to receive the maximum Experience points. It is suggested to try to corner most of the enemies.

Kingdom Hearts II
The children must be trapped in Present Boxes after beating them and making them dazed though, they may get up if not captured fast enough and if left in the boxes for too long they will escape. Sora must use the Reaction Command "Capture", once all three are caught the battle is over.

The three children also serve as enemies in the Gift Wrapping minigame. They will run around in front of the camera attempting to destroy the boxes for the presents and try and distract Sora. They can be stopped/slowed down by shooting them with presents.

Kingdom Hearts 358/2 Days
Since the field is big and full of obstacles, Roxas is going to have take them out one-by-one. Start off with Lock as he has the slowest running speed and can be a threat as he throws pumpkin bombs as an attack. Watch out when he readies the attack and block it to counter. His defense is high, as with Shock and Barrel. Next, move on to Shock. Lock onto her and chase her (using Air Glide or Dodge Roll is effective). When she readies her attack, be ready to block. When she hits the block, she'll drop to the floor startled. Attack her repeatedly until she has fainted. Finally, target Barrel. He has a roll attack which can be blocked. He is a sturdy fighter as he will not stop even if he is hit repeatedly, so it's effective to take him out by using combos or limit break.
