Kisame may have a large amount of physical strength but not the strongest. Senju clan have the strongest clan *as a whole*, All raikage are physically beasts, All jinchuriki are pretty strong. But the point of this thread is that if you strip all other ninja of all there stregnth increasing abilities that Kisame is stronger than them. What is the point of that? To prove that in a fight where the rules are no chakra, no tailed beasts, and noo jutsu that kisame will be stronger than MOST BUT NOT ALL ninja? That is a complete waste of time argueing whether or not kisame is the strongest ninja not using chakra becuase thats the way ninja make up for not being naturally strong THEY USE CHAKRA they use their tools and thats all chakra is for ninja just another tool.
Lets assume that none of these ninja are using chakra based attacks VS kisame.
Killerbee is able to take on giant gorillaz. I havent seen kisame take on a giant anything.
3rd and 4th raikage train themselves to fight with taijutsu that gets enhanced with lightning nature. If they remove this lightning they are still physically stronger than kisame. The nature only helps increase speed and reaction speed, not strength.
Gai would completely wreck kisame in a NO chakra fight.
Tsunade was able to crush the ground when we first saw her fight orochimaru. I havent seen kisame do any such thing.
Hashirama and Tobirama were stated to have superhuman strength by Sarutobi. They were senju who were stated by madara to posses the body of the sage.
I feel all of the characters ive mentioned is physically stronger then kisame even without the use of chakra.
But my entire point is that there will be just about no situation in naruto when niether party is able to use chakra to enhance there abilities and skills. If ninja are unable to be and act like ninja in a ninja manga whats the point of the manga.
When making comparision is being made ALL abilites must be taken into consideration, you cant just omit abilites as you want. You can try and prove why they will fail but you cant just erase them from a characters move pool.
