"Jesus!" Iron Man startled as Tony flinched then spun around to glare at the Scarlet Witch and narrowly miss the bolt. It did distract him enough to widen his eyes and stare back down at Iron Man where it struck, harmlessly enough as the armor redistributed the energy in a way both Tony's were sure flesh wouldn't. It was Iron Man, though, that continued, "Are you crazy?" The goal here was definitely not to Kentucky Fry Tony, but it was good to know how she would do it when she got the chance. Unfortunately, he really didn't need his doppelganger knowing what the hard limit was because he was 95% sure they didn't share moral restrictions.
Before Tony was given the chance to prove that, Iron Man slapped his overcharged and very warm glove down on Tony's foot (pain in his crushed wrist jolting up his arm and fairly paralyzing him there) and discharged that lightning bolt. The toe of Tony's shoe exploded through Iron Man's fingers, and Tony didn't even make a sound as he hopped away, face screwed up in pain and fists clenched as he splattered the impacted ground with dark blood from what remained of his foot. Maybe he wouldn't be so sure he had the upper hand now. The fire was still a surprised, Iron Man wasn't anticipating fire.
The veins of Tony's neck stood out and glowed with the impossible heat of it as he spit a scorching breath at Iron Man first, then turned up toward the Witch who tried to do the same to him. He hadn't even paused to inhale by the time he was balancing on his assaulted foot again, whole bones reforming to take his weight and finish this fight.
