Connor, along with his brothers, trained with his father with several firearms, and with hand to hand combat. He and his brothers were always devout Catholics. He discovered his powers shortly after he and Murphy moved out of their parent's home. He and his brothers became vigilanties against the DUP. Neither of them have currently been identified or even seen (without anyone who did see them dying.) He and their family have a special prayer that they say after killing someone.
"And shepards we shall be. For thee, My Lord, for thee. Power hath descended forth from Thy hand Our feet may swiftly carry out Thy commands. So we shall flow a river forth to Thee And teeming with souls shall it ever be. In Nomeni Patri Et Fili Spiritus Sancti."
Marksmanship- He and his brothers are skilled with firearms and use them in tandom with their powers. Connor typically carries two suppressed pistols, a sniper rifle, and a carbine rifle. (Taken from a DUP.) He uses these as his primary form of attack, using his power much more for defence.
He can manipulate his biology in various ways.
