Stetmann designed the first prototype with scientist Isabella Yorin for a Dominion military cyborg program, however, after he learned that their testing was being forcefully done on inmates of New Folsom Prison, Stetmann sabotaged the project and destroyed his prototype. During the Defenders of Man Insurgency, the design was replicated and redesigned for more humane deployment and operation at the Ryno Dscience facility, and removed the need for integration with a cybernetic body.
