OT Avengers
The old suit didn't hold up quite as well as Tony remembered, denting under the force, the face of the repulsor shattering then making what would be a very unnerving crunching noise if Tony wasn't otherwise occupied. The rest of the suit could absorb the shock that Nick tried to give him, but the repulsor let the energy that the suit couldn't transfer travel directly to his heart. It singed the already scarred skin surrounding his implant and his heart gave a disorienting stutter, making him hiccup then hyperventilate, seeing black even when he opened his eyes. Still, he made a blind grab for Nick's hand, catching two of his fingers and giving a sharp twist to snap the bones, hoping that was a bad enough hit by Wanda's definition. Keeping his heart beating was one thing, but Tony really didn't ever want to hear Nick laugh like that again.
