You said "especially being under water, so they would just keep regenerating."
Lightning puppet makes lightning
Water is a conductor of lightning
Lightning spreads around Water dome, thus negging all the sharks

Idk about that but I don't see Kisame trapping him I mean Kakuza can't use massive Fire and wind style jutsu Kisame only has water it would be a drought out fight think Kisame would win eventually

Yea I agree Kisame the tailless beast stilll Tobirama>Kisame with one flying raijin strike

He'd simply regenerate and ftg isn't working well underwater.

He regenerated his heart, his abs, his intestines, etc. So I don't see why not.
