Queen of Hearts
From Memory Alpha, the free Star Trek reference
The Queen of Hearts is a fictional character from the book Alice in Wonderland written by Lewis Carroll. She was quick to anger and favored ordering a beheading for those who infuriated her.
On the Shore Leave Planet, the Queen of Hearts and several of her knaves appeared to Leonard McCoy as an illusion, with the intent of pursuing and declaring "Off with his head!" (TAS: "Once Upon a Planet")
