Nguyen was an employee of the Advanced Threat Containment Unit, an organization secretly run by HYDRA with the grand purpose of bringing back their leader from Maveth. As part of their plan, HYDRA gave their employees, including Nguyen, fish oil pills in order to discover if any were Inhuman. All that were, Nguyen among them, were put into stasis with Suspension Gel and stored at the ATCU facility to wait for a time where the HYDRA leader would need an army.
HYDRA found a way to bring their leader back, and Nguyen and the other Inhumans were brought to the HYDRA Castle in Gloucestershire. While still in stasis, Nguyen and the others were discovered by Lash and he killed them all.
