Titan

Titan was the henchman for Monster X during the Double Vision mission. He was shot and killed by Zosimos Q. Cosmos (The Host) in self-defense in the Unknown Forest. He had a glowing green face with an intimidating mouth.

The exact reason Titan joined Monster X is unknown, along with all of his past. It is presumed that Titan is another mutant due to the effects of the X virus, under the control of Monster X. It was because of Titan's carelessness that The Host was able to escape Gold Industries with a handgun during Double Vision.

Since the X virus can re-animate those who are infused with it, it is possible that Titan could be brought back to life.
