Metal Gear Solid! Episode 6 - Psycho Mantis Boss Fight he not getting into my head!

This Boss back it's day was amazing xD i remember finally figuring out the port thing and it blew my young mind!
Psycho Mantis was a psychic member of FOXHOUND, who participated in the armed takeover of Shadow Moses Island in 2005. He wore a special gas mask to help prevent people's thoughts from "forcing their way into his mind."[3]
In 1984, Mantis primarily found himself attracted to those who harbored negative feelings, thus accompanying the "Man on Fire" in his pursuit of vengeance. He would later work as a child soldier for XOF under the code name Tretij Rebenok (Russian for "Third Child"), until finally defecting from the organization after allying himself with a young Liquid Snake.
