Everyone else on the crew has a dream they seek to fulfill, requiring insane amounts of dedication, inner strength of both types, and willpower. Most of them ALSO have a massive one-upper compared to a normal human, if not multiple ones.
Zoro is a normal guy who got his ass kicked as a kid, and respected said asskicker so much that when she died a tragic death, he dedicated his life to fulfilling her dream, and later on also dedicated it to helping Luffy and the others attain theirs. It takes great strength to live for your dream. It takes even greater strength to live for someone else's.
Besides, he's literally just a normal guy who lifts weights a lot. Luffy is rubber, Nami has a supernatural sense of direction and the environment, Sanji can FLY and LIGHT HIMSELF ON FIRE, Chopper can shapeshift, Robin can spawn multiple limbs, Franky's a fuggin' cyborg, and Brook is undead...
...and Usopp is there too I guess.
I kid, Usopp is my second favorite.
But Zoro really is just some random dude who trained stupidly hard and is now a fucking god at swordfighting, all in the name of a fallen friend.
What a badass.
