The Weapon Master is one of the Endo-Squad's power members. His past is covered in shadow by the the Weapon Project. Even he knows very little of himself before his abduction. As his title would suggest Mastie is a master of all forms of weaponry. While in the weapon project Mastie spent most of his time training on combat rather than stealth skills. This leads Matie to be very closed minded and straight forward. Even though he carries firearms at all times Matie's weapon of choice is his sword. He is one of the most skilled swordsmen on the planet. He is very agile and strong, but also very rash. His temper gets the Endo-Squad into trouble many times. After their escape from the Weapon Project and X's accident involveing plasma Mastie fled into the wasteland and found Wizard. Because Mastie showed extream loyalty and tanacity Wizard felt pity upon him and endowed X with his cybornetics. After that Mastie developed a brotherly friendship with X aiding him through his largest struggles, never leaveing his side, and eventually gave what seemed to be his life to save X.
