The Queen of Hearts

The Queen of Hearts is a character from the book Alice in Wonderland by the writer and mathematician Lewis Carroll. She is a foul-tempered monarch, that Carroll himself pictured as "a blind fury", and who is quick to decree death sentences at the slightest offense. Her most famous line, one which she repeats often, is "Off with their heads!"
The Queen is referred to as a card from a pack of playing cards by Alice, yet somehow she is able to talk and is the ruler of the lands in the story, alongside the King of Hearts. She is often confused with the Red Queen from the sequel, Through the Looking-Glass, although the two are very different.
