Other than Sherlock Holmes (whose physical stats we simply don't have a clue about) there is not a trope of "the really smart guy can kick ass of anyone else no matter how well trained they are". The smart guy may outthink their enemy. They may use the (completely false) fiction of using 100% of your brain to have psychic abilities. You have the martial artists taking down people twice their size (also dumb, but it's common imagery) but that's dexterity and training in D&D not intelligence.The point you made was that "art and tropes matter". You have, thus far, failed to indicate what existing art or tropes would be contradicted by fighters whose mental stats contribute to their success in combat.
There's exactly 1 example that I know of (Sherlock Holmes) where intelligence wins physical combat.
You do you, I'm not continuing this. There's no point, we're just going to disagree.
