Hopkins, May

The diminutive Minnie-May Hopkins worked as an underage prostitute in a Chicago Chinatown brothel before her iron resolve, talent with explosives, and excellent demeanor with customers at the Gunsmith Cat Gunshop led Rally Vincent to hire her as an assistant. May can conceal armed explosives in almost anything, making her equally skilled at locating and disarming bombs set by others. She typically carries a variety of grenades and explosives hidden on her person, ranging from harmless smoke bombs 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.
