Gray was employed in the Advanced Threat Containment Unit, which was secretly run by HYDRA. As part of their grand plan to bring back their leader from Maveth, HYDRA gave their employees, including Gray, fish oil pills in an attempt to create an Inhuman army for their leader to command. Gray underwent Terrigenesis and unlocked Inhuman abilities. Gray, along with other Inhumans, was put in Suspension Gel and stored in the ATCU facility in preparation for when HYDRA accomplished their goal.
HYDRA found a way to retrieve their leader and Gray, with the other Inhumans, was brought to the HYDRA Castle. While still in stasis, Gray was killed when Lash discovered and murdered the Inhumans.
