Once the most feared soldier in the Confederate Army, now the most feared being who ever walked the Earth, The Saint sold his soul after a tragedy, so that he could continue to kill.
Little is known of the man who would one day become the Saint of Killers. There is rumor and legend, and only a few knew even some of the truth.
The Saint of Killers is virtually omnipotent, to far greater extents than is seen in comics especially for a non-cosmic character. He possesses a durability on par if not surpassing that of Superman, so powerful that it allowed him to be hit by a nuclear missile and remain unscathed and his clothes undamaged. He then simply shrugged it off and said, "Not enough gun."
He is also, and was before gaining his powers, a champion marksman. He is so quick on the draw that an ordinary man cannot even watch it happen. He also has perfect aim and through many odd circumstances he has still managed to always hit his desired target.
The Saint of Killers is also superhumanly strong as evidenced by the fact that he stood his ground when Cassidy crashed into him with his truck and he did not move an inch.
But the power of his which is stronger than all the others is his hatred. It was his deep hatred that extinguished the fires of Hell, resulting in him being expelled from it.
http://www.comicvine.com/saint-of-killers/29-10522/Matt Cordell was once an honest, effective cop. So effective that he was dubbed "Supercop" by his fellow officers. However, his refusal to go along with a corrupt administration led to his framing and sentencing to Sing Sing Prison... the very same prison where many of the vile criminals he brought to justice were sent. Cordell was brutally murdered by these inmates, but his soul refused to rest. Fueled by a now supernatural rage to seek vengeance against not only those who framed him, but the city corruption itself, Cordell rose from the grave. His rage now blinds his sense of justice, and he sees all as guilty. While he ultimately targets the corrupt and evil, he has no regard for those in his way, especially innocent bystanders.
Cordell possesess near superhuman strength, as he is easily able to throw people around with one arm. He also has the competency to operate equipment, plot, and carry out plans, so he is far more formidable than typical zombie fare. Conventional weapons are effectively useless against him, and seldom accomplish more than just slowing him down for a bit. The fact that he was impaled in a truck crash that sent him into the ocean, only to rise again, shows that he has practical invulnerability.
