You know whats the one thing i always hate avout stories, where the mc becomes op statewise? the speed/agility attribute. in our case, when taking into consideration how strong just the hits of his fists are (since both strength an agility have the same number) he should be able to move exteremely fast, like at least 100 times faster then usain bolt (meaning like 1km/s). speed is the most crucel aspect in every fight and an mc of that kaliber could with ez just take his weapon away or hit him on his body instead of the sword (one could make the argument here, that the mc just wanted to test his strength, but he said earlier, that it would be a nice weapon foe his subordinate so destroying such a good weapin isnt really optimal).
