Lab 7's only successful psychic experiment, most of Brain Drain's body was destroyed in the disaster which consumed the facility. The experience left him doubtful of human reliability, so as far as he is concerned anybody who falls short of his expectations is to be replaced. Because of this ruthless approach, he soon became the widely-feared second-in-command of Lab 0. An expert at analyzing others, he even believes he can construct superior mechanical replicas. Brain Drain is now the "psychic director" of the highly secretive ASG Lab Zero.

In this game, he serves as one of the primary antagonists, he uses his expertise to enhance the troops for The Agents of Darkness. And has developed special devices that can experiment on potential "chosen one candidates" and see if the experiments go according to plan to find who will be the host to revive Dust of Osiris!

Brain Drain is calm, cool, sophisticated, and incredibly arrogant. His voice also sounds distorted too as a result of his robotic body.
