Kingdom Hearts 358/2 Days
''This newcomer to Wonderland splits in two, attacking as a pair. Unless both halves are defeated at the same time, they will continue the cycle of merging and splitting.'' ''Counter its flamethrower with ice magic—Blizzaga if possible. Aeroga will halt its fiery spin attack.''

Strategy
At the start of this battle, Lock-On to one of the Crimson Pranksters' head and begin attacking with the Keyblade. It does not matter whether you attack the Heartless or its copy first, as they both have HP that must be depleted. Use caution when attacking at close range, as the Crimson Prankster may attempt to swat you away.

When the Heartless Boss leaps into the air, get out of its way as fast as possible. Otherwise, you will suffer damage from the shockwave and wall of fire it emits as a result of its jump. The beast may also create a pillar of flame directly in front of it. You should be extremely careful when the Boss spits a stream of fire at you. This attack can be predicted, thus easily avoided, when the matches either one of the Heartless carries ignite in flames.You should also be cautious when the Heartless starts to spin whilst covered in flames.

Do not get cocky once the first Crimson Prankster falls, as the other will quickly revive it in a cloud of purple mist. The process of this battle then repeats itself from square one. While defeating two Heartless Bosses may seem a bit overwhelming, this fight should be easy if you make use of healing items and your Limit Break. A good strategy to defeating this boss is by lowering both their health bars down to the last bit of the last bar without killing them, then kill one and quickly kill the other before it can revive its fallen comrade.
