A revolver is one of the weapons shown in the manga used by notable characters in the story such as the Mad Hatter and also Alice. Later in the series, the Dormouse used this weapon for a massacre at the palace.

As the Mad Hatter first arrives at Wonderland, he is commanded by the White Rabbit to go to the Queen's Castle and thereby, the Queen throws a gun to him where his duty is to protect Alice who are hostile towards him/her.
