I think the problem of these post are that, too many naruto fans watch naruto, kishimoto has been coming with overpowered or god-like shinobis, and we are calling the sannins weak. No mean for disrespect, but dude, the one who posted this thread you sound like a kid in his 13 and 14. You still don't know what powerful is, too much dragon ball z like shit you probably watch. If a character is not an overpowered super saiyan like naruto, sasuke, killer b, a and the third raikage, they're are not strong. If Kishi didn't make him to have godly powers they are not strong. All three of them are considered kage levels. Orochimaru (high kage), Jiraiya (high kage), and tsunade (mid kage).
Orochimaru was given the title, but was later rejected because of his twisted evil ways. Then the third gave it to Jiraiya, but he rejected it, and then he gave to minato. Later after the third's death Jiraiya again was given the title, but denied it and gave it to Tsunade, but no one seems to mind because they know she is strong.
Maybe you were waiting for one of them to make a powerful blast that could take a a whole city to say they strong. Being strong in the shinobi world takes more than overwhelming power. It takes high skills, intelligenge, good chakra use, tactics, great uses of ninjutsu, taijutsu, and genjutsu, courage, and discipline. Akatsuki didn't attack naruto because Jiraiya was with him. Why didn't Pein just get out and beat jiraiya like he did to the six tails. They know he's strong. Kisame even said that jiraiya was stronger than him, and we know kisame is probably the fourth strongest in akatsuki after Itachi, Pein, And Tobi. Even Pein said if jiraiya knew of his bodies' secret he would have not won, and what does that tell you.
Akatsuki searched for orochimaru, but could never find him. And Akatsuki would never risk any men to kill orochimaru. The guy is half immortal. 4 tails couldn't kill him, and he had no hands, Sasuke got lucky for plot no jutsu, and yet still lived inside him until Itachi yanked it out of him. and yet he still lives inside kabuto. The third said there was no one who could beat him in the village. Tobi even respected the guy for his knowledge of all things that happened to Madara and Hashirama, and all jutsus and the guy wasn't even born yet. And it has been stated many times in the story that he's stronger than Jiraiya, even by Jiraiya himself.
Tsunade is very strong, she is a kage level, just because kishi hasn't showed a lot from her yet, don't come to conclusion oh she's weak. She beat both orochimaru with no hand and disable manda. Name me how many shinobis in the narutoverse that could take out manda, not many just a few dozens out of 80,000. She could heal a whole village of thousands. Her strength is inhuman, her taijutsu also high. And we have yet to see her full power, or even half of it. Strongest kunoichi in the narutoverse, than if she's weak so is mei terumi (fifth mizukage), and chiyo.
so man your thead is just childish and nonsense. Kishi did state to be a kage you have to be the strongest in the village. So why would kishi made her weak for. If you a kid, you're still need to understand the meaning of power and being strong.
