Chipmunk's story is shorter, funnier, weirder, and less fantasy cliche. Basically the short short version is she worked for the CIA in modern times, was part of an experimental program to create more perfect assassins by recombinant DNA therapy (she was zapped with Chipmunk DNA, gained powers of super agility and speed and preternatural accuracy with thrown nuts, and later other projective weapons), things went fine for a while as she used her new Chipmunk powers to blast the bejeezus out of the United States's enemies, then eventually got pissed off at government BS, went rogue, and started blasting the bejeezus on a freelance basis, then eventually became a part time hero when freelance lost its allure, then was captured by the Circle of Thorns, tortured, escaped through a portal, and came to find herself in Azeroth, where even the greatest gnome technology could not replace her love of automatic firearms, so she trained in the next best thing, warlock power! The rest is history, and now you know where she got the name Chipmunk, and the origins of her bloodthirsty and deadly nature.
