1. Just because we've seen more about Kisame, doesn't make him the greatest. Up to now, to the world Tobirama is known to be the greatest! While he is busy doing handseals, Tobirama simply does one and outcomes him. Not saying Kisame is not powerful. He had the chakra comparable with one of a tailed beast...1. Kisame is the greatest water style user to date. he created a whole ocean.
2. We have seen many ninja due water style without water
3. He banned it. Plus his was worse than Oro and people say Oro did a half version compared to kabuto.
4. Who cares
5. We don't know his feats in this category at all.
I am not saying he is weak or anything of the sort. Just saying what made him special has become the norm.
2. Yet he was praised the best from all. And when someone says he is the best, well, it's for something.
3. He banned it for a reason. If he wouldn't have created it, Oro and kabuto would've done nothing.
4. Some of us do.
5. Well, you've seen it at Minato who said he was highly skilled when it came to that. I don't think he was talking for nothing, again.
So give the man some credit. He is indeed underrated.
Also, Hiruzen who is said to be the God of Shinobi couldn't dispel the area filled with darkness (genjutsu) that Tobirama casted. It is true it was in the anime, but think about it, whenever they add something in the anime, I am sure they do it with Kishimoto's approval because if not, they would go under the infringement laws protection so, whenever you say that something in the anime is not cannon, think twice.
Anyway, I rest my case.
