i have something in my mind that i should tell but u might think i am crazy but here goes
Luffy vs. Lucci
Nico Robin vs Blueno
Zoro vs Spandam and Kaku
Sanji and Chopper(might be chopper) vs tao tao pai guy or watever
Nami vs Kalifa
Franky vs the big hairy guy who wants to commit hara kiri
it all goes from the cover ch.377
who knows, i might be wrong
