But to continue with our debate. Batman might have the great technique to strike sensitive regions and nerves with his toys too. But Cap is protected with a vibranium diaphragm that doesn't act as just protecting barrier to his sensitive regions but doubles as vibranium protection when it's his turn to strike.
His turn to strike? Don't be absurd. You think Cap's sensitive regions will last long against Bruce's vibrating palm technique?
Ionno, that diaphragm is pretty large in diameter. The diaphragm is also really good at absorbing vibrations.
