Jason Rusch is an employee of Mercury Labs. He is also a grad student from Hudson University and a former member of the F.I.R.E.S.T.O.R.M. project. During his time with the project, he co-wrote an 800-page paper with Professor Martin Stein regarding it.


Jason Rusch was a part of the F.I.R.E.S.T.O.R.M. project with Professor Martin Stein, during which time he co-wrote an 800-page research paper with Stein and posted it online. However, after Stein's disappearance, F.I.R.E.S.T.O.R.M. was confiscated of all of its research by the army. Following the ordeal, Jason became paranoid.[1]

Jason mailed in a résumé to S.T.A.R. Labs and Mercury Labs, eventually being given a job at the latter.[1]

Over a year later, Jason met with Caitlin Snow, who wished to know about the F.I.R.E.S.T.O.R.M. project. He expressed his paranoia and gave her a brief overview of the project and his history. They parted ways, as he didn't want to speak of it anymore.[1]
