I had a Beasts mastermind named Ellie Mae Crumpett, modeled on Elly May Clampett of"The Beverly Hillbillies". Her secondary was Poisons: the debuffs were her own cooking (notoriously bad, on the show), and the buffs were Granny's cooking. Ellie Mae's battle cry was, "Git 'em, critters!"
This is an excellent concept for an MM. If I knew how to make hands clap, I would.
