He is a US Marine who served in Afghanistan until he was severely injured by an improvised bomb attack by the Taliban. He was taken to my hospital and to my underground lab to revive him replacing his damaged organs and bones and injecting it with my inhuman DNA reborning. He woke and saw what happened to him. He is confused if how he died but remembers the cruelty of bad people harming innocent people as well as their own people. I did revive him but also turned him into a superhuman and codenamed him "Zombie Warrior Man" after I told him the truth. He understands and lets him choose what weapon he wants to use. I even said "You have my brute strength. Take any weapon you want" He picked the Chainsaw because it reminds him of home (He's confirmed he's from the Southern Americas Texas, Lousiana or Tennessee)
I saved him by turning him to a Half Human Half Zombie that use weapons using his Military Experience and Brute Strength from Chainsaws, Axes, Shotguns, handguns even any improvised weapons. He can know handle explosions and gunshots
