Queen of Hearts

The Queen of Hearts is the short-tempered and mostly villainous ruler of Wonderland. She appeared for the first time in Disney's "Alice in Wonderland"

Kingdom Hearts
''A queen of Wonderland who lives in a castle with decks and decks of card soldiers. Selfish and short-tempered, she beheads anyone who crosses her. She think Alice tried to steal her heart.''

She struck terror in our hearts in "Alice in Wonderland" (1951).

Kingdom Hearts: Chain of Memories
"A selfish ruler who commands an army of card soldiers. A heartless stole her memory, but she accused Alice and put her on trial."

Kingdom Hearts
The Queen of Hearts was an intra-world "villain" that appeared in a major role in Wonderland. Despite insisting on Alice being decapitated for trying to steal the Queen's heart, the Queen was apparently in no way associated with Maleficent. Also, as she was not entirely evil, the Queen isn't completely a villain, even though she and her Card Soldiers are bosses.

During the said battle, if Sora thrusted forward with the Keyblade when attacking the Queen, she would topple over. This temporarily stunned the Card Soldiers.

Kingdom Hearts: Chain of Memories
The Queen appeared in Castle Oblivion as a figment of Sora's memory. In the memory recreation of Wonderland, the Queen accused Alice of stealing her memory and sentenced her to death. Even after Sora and co. found the real culprit, she still refused to believe that Alice was innocent. Fortunately, Alices's quick thinking pacified the Queen and no one had to lose their head.

Trivia

 * The Queen of Hearts is one of only four central Disney villains not affiliated with Maleficent, and the only Disney villain at all that does not use Heartless to attack Sora - she uses her card soldiers instead.
