Headsmash

"In the lurid city of Ares, Smash is a trusted officer of the Horde, a brutal syndicate. As an angry orphan, he was hand-selected by Maurice, the Horde's capo, to be groomed for leadership. After being sent on a mission to claim a powerful serum, Smash is left for dead and his girlfriend and unborn baby are taken by the very group that he swore allegiance to. He returns, armed with a serum that gives superhuman strength, and vows that he won't rest until his family is safe and revenge is taken upon those who betrayed him."
