John Ward is an exorcist. He has seen many demons, many of which have left him with mental scars. He's not very open with his feelings, but when he is, it all comes pouring out. He's kind and compassionate but has a lot of hidden traumas. His first exorcism led to the death of his teacher, Father Allred, and Amy Martin, a poor possessed girl. He now fights a cult run by Gary Miller, alongside his friend and father figure, Father Garcia. He also has a small crush on Lisa Pearson.
