Trok was known to be a supplier of traceable fuel. During his activities, looking for spare parts, he managed to acquire the half of a Chronicom vessel, which had previously been destroyed in an attack. Trok inspected the ship's fuel lines and found out there was still fuel in it.
Later, Trok's facility was approached by the Zephyr One, with its crew in dire need of fuel. After sending a message informing Piper and Davis that they would be boarded, Trok entered the aircraft with three guards, asking them to identify the S.H.I.E.L.D. agent facing them and mocking her behavior as she demanded to be handed over fuel for free. However, Trok was disillusioned when the agent turned out to be Quake, who destroyed his guards' weapons with her abilities, prompting them to flee.
Remaining alone, Trok attempted to fight Quake on his own, but he was quickly overpowered. He was then told by Jemma Simmons that they were looking for someone and captured for interrogation. Hung upside down with a chain, Trok was initially reluctant to divulge any information, but upon facing death due to the stronger gravity of the Zephyr One which could severely affect his body, he revealed that he had bought one half of the spaceship S.H.I.E.L.D. was looking for, and directed them towards it.
