Unless he has sagemode to magnify his elements attack into another level then no, his elements attack contain alot of chakra and that is the food for Kisame ultimate attack.Kakuzu was underrated
He had a Long experience and his Earth Style makes him already Jo Nin Equal in my Opinion. He has all Elements and could take on Kakashi, Ino, Choji and Shikamaru all at once. He also is immune against almost every physical attack with exception of Lightni9ng and maybe those God Tier abilities.
Kakashi had the first time he was pushed to his Limits. Also if Kakuzu gets sliced in pieces he can reeattach himself and use his Jiangu ability very flexible. He could merge with htme and use Fuuton and Katon combination. With his Earth Style Combat technique and the Elements and Jiangu there are a lot of characters he could take down.
I think Kakuzu was Number 4 or 3 so equal to Kisame in Power but i do not know who would win
Him or Kisame?
