Crocodile was not the strongest luffy was he beat crocodile and how about ace??????

Gomu gomu no mi is human human fruit hito hito mo mi is model nika.

How about overhaul tho

Pan is a good character tho she might have been a little bad the first bit but she is valuable member now.

I bet emu has like a mythical zoan + logia or sm like that.

Aizawa would definitely beat all might with his eraser quirck and his capture scarf. Other than that I don't think anybody.
