Isnt Kisame The Strongest Of The 7 Swordsman?

[Rhoxors]

Correct me if I'm wrong but Kisame killed Fuguki?

That's how he obtained Samehada.

If Kisame was revived Kakashi wouldn't have beat the Swordsmen, it's for the plot.

No... He simply had no DNA of Kisame, he kinda got chomped up...
How much I would like to see him return, there was no DNA (At the time)
