Patricia "Patti" Thompson and Elizabeth "Liz" Thompson are two sisters, who take the form of Twin Guns and pair up with Kid. Patti is very naive and childlike, speaking like a small child and finding amusement in very trivial things. She constantly laughs, even during extreme danger, and she believes everything to be a game. She is not very smart, and while testing, spends her time making her test papers into an origami giraffe. She often shows a psychotic rage in order to encourage her sister, though she quickly switches back to her carefree self. They used to live on streets of Brooklyn, where they would mug people in order to survive, though they joined Kid after admiring his dignified soul. Patti is a skilled martial artist and each sister can wield the other in their weapon forms.
