At this point I am certain he only loses to first mates.Queen, Jack etc. don't really stand a chance.

Overall this kinda open me up the question how strong Whitebeard commanders been. I mean Izo is not even a commander and look what he did. Significantly winning against one CP0 in a 2vs1 fight, while Drake in team fail to do. I never imagine that Izo would perform this good against the CP0 after they clapp Drake and co.
