Psycho Mantis

Psycho Mantis is one of the renegade members of FOXHOUND who took over Shadow Moses with the GENOME Army. He has the amazing ability to read people's minds and move objects via. telekinesis. He used this power to attempt to get the Metal Gear REX launch codes from DARPA Chief Donald Anderson, and from the President of ARMSTech Kenneth Baker.

Psycho Mantis' mother died during child-birth. When he gained the ability to read people's minds he read his father's mind, only to discover that his father hated him, blaming him for the death of his mother. This caused him to go psychopathic and, using his telekinetic powers, he burned down the village that he lived in, killing everyone who lived there.

He wears a gas-mask to help him, because when he's not wearing it people's thoughts "force their way into [his] mind."
