She is known for her fierce temper and frequent exclamations of "Off with their heads!" when she feels wronged. The Queen is often depicted as a playing card, representing authority and power in the whimsical world of Wonderland. In various adaptations, the Queen of Hearts has become a symbol of tyranny and irrationality. Her character is often portrayed as both comical and menacing, embodying the absurdity of the rules in Wonderland. She is frequently associated with playing cards and the Red Queen from the sequel, "Through the Looking-Glass."
