It039s all in the name with Vicious: he is ruthless bloodthirsty cunning and ambitious willing to do anything in order to secure a position of power. He is a member of the Red Dragon Crime Syndicate in Tharsis and is often referred to or depicted as a venomous snake. His weapon of choice is not a firearm but a katana which he wields skillfully even against gunwielders. After Spike039s supposed death Vicious also leaves the Red Dragons briefly to fight in the Titan War of 2068 although his precise motivations for enlisting are debated. from Wikipedia
