I’ll take Kisame.

Kisame, High-extreme diff. Hiruzen's knowledge of every jutsu is giving him so many ways to come at Kisame. But in the end, Kisame's ability to absorb chakra is bringing him this W.

@RadicalJD What if he was up against prime hiruzen? You still think he takes it or nah?

No. Fused Kisame ought to give him a run for his money though.

Hiruzen, high - extreme diff.

Gonna go with Hiruzen here
