anyway Guys calm down , it's Zoro vs Kizaru and dobberman spoiler is fake because :

The frontier Dome where Zoro and other fellas are in is blocked in and out so neither straw hats can run away nor Marines can enter ; only Kizaru could enter there through laser manipulation.

So that leaves us with this hint :

who is fighting Zoro from Marine side if they couldn't enter besides Kizaru ?

Monkey ( Kizaru ) vs Zoro like shabondy and nice try Admiral tards in TL .
