 Risman is a trained hitman, so he is highly trained, like all the other Purifiers, who and have been shown to be capable of holding their own against both O.N.E.troopers and the X-Men.Their belief in the righteousness of their actions and their belief that they are fulfilling God's work by killing mutants is a source of great strength for the group, enabling them to commit acts that would make more moral, reasoned individuals cringe, and enabling them to hold their ground in the face of great odds or past defeats.
