Futuristic Earth/planet. Man is killed in 'Bloodsportish' fashion, but OUTSIDE the arena. Brother comes to visit, trains and joins fighters. He befriends one named Eddie. Eddie's sister is a stripper and... of course, the two fall in love (Avenger and Sister). A fourth character is the guy that trains him. He has the tattoo of a snake - might even be name of guy. HE is the bad guy, the brother's killer.

Help me, Obi Won Kanobee... you're my only hope! :)
