Marvis

A former member of the Mach Storm Team Marvis used to be Helmuts best friend and Sigmas mentor. However he had a falling out with the team which caused him to go on a rampage killing a member of the PKB. He was hunted down and captured by Helmut and imprisoned. However he was able to escape and tried to get his revenge on Mach Storm. Marvis piloted a Shadow Fox. Marvis is actually working for Alpha and later ousts Gummie to become the chief of the PKB. After his Shadow Fox is destroyed he gets a Styluarmor as a replacement. Furthermore he proclaimed in the battle after his escape from jail that to him his comrades and the team were nothing more that stepping stones to become the most powerful ZiFighter. This proved true even going as far as killing Graheme Sandras father years before so his plans wouldnt be ruined. Because he inadvertently sent Sandra down the path of revenge and in turn though her own machinations Blake one could say Marvis is the catalyst for the rift of hatred between Mach Storm and Savage Hammer.
