he may look like an owner of a small candy دکان ...but he was a deadly captain............and he never shown his true power yet...his bankai...he itself told that his bankai is deadly to himself ......and a deadly one.....and guess what the best part that makes him the most powerful person is that he can counter any attack if he see's it only once.....& his intellect is out of the world...............!!!!
Sakata Gintoki!!! This man here, has pulled of the Final gestsuga tenshou, is able to use multiple "STANDS", as seen from the "J-star victory vs" he can also pull off the kamehameha attack, he single handedly destroy a mobile suit, and last but not least....destroy عملی حکمت so yeah! strongest is what I'll call him XD
no matter how tough an ordeal is he always comes up on top... He is simply just too strong for anyone to beat him, there may be times when the enemy gets the upperhand but he would just come back with a vengeance
