Roger Jech doesn't have any superpowers, but he has a super ability: harm him, harm yourself in equal measure. Hit him with a right hook, your jaw breaks. Shoot him in the head, your brains blow out the back of you. Drop him in a war zone, your enemies kill themselves killing him.
Jech's a weapon to the wrong people and a savior to the right, but before he can become the latter, he must learn to harness his gift before it becomes his curse.
