INCREDIBLE! the madman has infinite stamina, he doesnt seem to tire at all. look at the speed and angle he is waving his arm, and the massive shockwave following the hand with every blow. to any mortal creature that kind of blow would be lethal- very possibly sending the target to the afterlife immediadly. can this man even be considered a human? the answer is no. there is absolutely no way a human could posess such physical strenght, stamina, balance and mastery of technique. this being is therefore superhuman and has easily transcended the limits of any living human being.
