[@Buddha] Okay so maybe as secondary power (sorry, brain couldn't help it). How about chi-manipulation. Like the "spiritual" energy from his body. It would increase the strength of his punches and indeed, maybe in the future take the shape of a short range projectile or whatever. Chi would also allow his body to become more flexible, stronger, etc. But his primary power blocks the usage of his chi (adrenaline flooded brain can't focus and keep cool to let the chi flow). So he rarely every uses it hence why it's considered a minor power. Again, just a suggestion.
