Many video games and movies set in a medieval-like fantasy setting feature implausibly huge weapons, which would be completely impractical in real combat.
Sometimes people defend the realism of such huge weapons by stating that the characters wielding them have superhuman strength. However, when real physics come into play, having superhuman strength still doesn't make these weapons practical. No matter how strong you are, swinging such a weapon would throw you off balance, unless you were bolted to the floor or you were so heavy that you would sink into the ground. Also, swords were very quick and nimble weapons, there is not much use in a sword which you can swing exactly once before needing to regain your balance (or get up again after you fell because of the inertia throwing you off your feet).
This led me to the following question: what would be the ideal melee weapon for someone with superhuman strength in an otherwise realistic medieval to early modern setting? Let's assume our hero is 5 to 10 times stronger than an athletic human, with no other superhuman qualities (except those required by this increase of strength to not break his bones or rip his joints apart)
It seems he would be much better off with a standard-issue sword, mace, or other historical weapon than with a huge and super-heavy contraption. As swords were used to cut or thrust (and not to chop, as mistakenly depicted in movies where knights hack slooowly at each other), where superhuman strength would not bring many additional benefits compared to an already athletic normal human, I would guess a common regular-sized mace or war hammer would be the best choice to make use of his strength.
Could there be a better choice than that? Given enough money and the best smiths he can find, could one design a weapon which would be better suited to utilize his strength, than a regular, standard-issue hand weapon?
