Game:Playing Card

The Queen of Hearts appears alongside the Card Soldiers and Crank Tower as a boss battle in Wonderland.

Kingdom Hearts
The Queen herself is very weak, as one hit knocks her upside-down. Her attack is also weak as she swings her heart shaped fan which causes minor damage. She taunts Sora after her attack leaving her open for an attack. The Heart Cards wield pole arms and should therefore be considered dangerous even when at a distance. The Spade Cards have axes and have a medium ranged overhead slash. She and the Cards can only be knocked out. Therefore, the actual target is the Crank Tower. There are four handles that must be destroyed before Sora can begin attacking the tower.

Unlike most enemies, the Crank Tower has "endurance" instead of HP, meaning that it takes a set amount of hits to defeat it, and the strength of those hits do not matter. The gear handles have an endurance of 9, while the Tower itself has an endurance of 24. By landing strong combos on it, Sora can stun all of the Card Soldiers temporarily.

Start by knocking out all the Card Soldiers to give more time to attack the tower. Knocking out the Queen and the cards at the same time will lengthen the amount of time the cards are KO'd. This will allow Sora to complete several combos on the crank handles. One or two Card Soldiers may wake up while attacking, but they will be quickly stunned by the combos on the Crank Tower.

Trivia
