It wasnt a good match up for him.
Kisame's water dome or his lake jutsu is a perfect counter for FTG kunai or seals.
i disagree i believe its the other way around
this match is horrible match up for kisame
Minato can do so many things to get out of that water dome
throw kunais
have a seal on some tree near by
summon frogs and minato goes one way the frogs go another and kisame has to pick one
if he picks minato the frogs get out and they reverse summon him outside the dome
if he goes after the frogs, Minato is too fast and will easily escape
and then if minato kisame go at it close combat he puts a seal on him uses FTG and kills him with either a kunai or a rasengan your choice
lol and he doesn't have samehada so how is he fast again? ( the OT didn't mention it)
