There are few things that can harm you. Not because you're an ultra Brute or so fast you can't get hit. No, you have impossible luck. No one harms you because they get hurt or humiliated or even killed because they tried. The harder, more seriously, and more violently they tried to hurt you, the worse the response from your power. You can still get hurt by accident or if a sufficiently durable and determined person tries hard enough. They might even live long enough to regret it.
