He will manage to open Kaido's scar, that's the role he plays on the roof and the build up of him getting Oden's sword which was used to create that scar to begin with.
@zzShinichi don't project your insecurities on me
I was on the side of Zoro vs King when many argued that he's not even strong enough to fight him, and was called someone who overestimates the SH's
I was on the side of Zoro vs King when many Sanji fans argued that Sanji should fight King, and some called me out for not siding with Sanji
I am on the side of Zoro vs King now when y'all get flustered over the fact that he's on the roof and somehow you think everything is set in stone, and the fights will go smoothly exactly as they are set up at this point in time.
You might as well also argue that Sanji will beat up Black Maria because she's the closest opponent, just get caught in the moment all the way. Actually, i've seen some make that argument.
I'm simply not being shortsighted and not letting my feelings get in the way of how i judge things in regards to these match-ups.
