Diminuative Minnie-May Hopkins was working as an under-age prostitute at a brothel in Chicago’s China Town before her iron resolve, talent with explosives, and great demeanor with the customers at the Gunsmith Cat Gunshop caused Rally Vincent to hire her as her assistant. May can hide armed explosives in just about anything, and is therefore equally expert at finding and disarming bombs placed by others. She usually carries a variety grenades and explosives hidden about her person, ranging from harmless smokebombs to deadly fragmentation grenades.
May learned her trade from Ken Taki (a.k.a. Takizawa) a special effects expert and infamous bomb maker. He is a former mob hitman who has gone straight.
