team 2 wins
mihawk cannot even cut diamonds, adamantium is too durable for mihawk and kizaru to damage
none of these guys can react to Weapon XI teleporting and building level heat vision is too much for these two
kizaru cannot move or react at lightspeed. if he can move at LS he should have run 8 times in circles around the globe in less than a second nor matches the destructive capability of weapon xi lasers
mihawk's sword would just break off when touches logan's claws and skull since it cannot cut diamonds
kizaru cannot become intangible when weapon xi blitzes him and blasts his head off with heat vision
team xmen wins one piece sucks
