Who cares about what Choji did before?
What matter is... where is he now?
And now, he's way on top of the strongest.
To me, he's 3rd, right after Naruto and Sasuke.
There are some that might have a chance against him (Lee, Neji, Shikamaru, Sakura), but I think that overall, he's way stronger than them.
He took care of all the Zetsu by himself.
And he took down Asuma, Kazuzu and Hizashi all at the same time for god's sake!!
If that's not enough to proove how strong he is, then what is it?
Now, answer this:
Can Naruto and Sasuke defeat Asuma, Kakuzu and Hizashi all at the same time?
Yes, and that's why they are above Choji.
Can Neji, Lee, Shikamaru or Sakura do the same thing?
No, they can't. They just aren't strong enough.
And that means that Choji is stronger than them.
It's as simple as that.
Right now, this is how i will rank them:
3. Lee (if he can go up to at least 6th gate now, i will put him ahead of Neji)
bringing down all the zetsus and kakuzu wasn't just choji it all these squads: kitsuchi squad 2 (close range fighter) and darui squad 1(mid range fighter) and shikamaru squad 4(long range fighter division).
kitsuchi was in the top of all zetsus bodies choking the last zetsu, all these shinobies helped out to bring down down zetsus and kakuzu and even tenten destroy one of kakuzu mask with the fan.
Why i said bringing down and not defeated is because they haven't defeated yet kakuzu is still alive and hizashi is still fighting which even chijo says this: you all will have to finish kakuzu and hizashi-san and i'll fight that thing refering to demon statue(Gedou Mazou) which choji tryed to hit gedou but gedou blocked it and sent him flying away.
Choji became stronger than he was before, i know that choji is climbing to be a strong shinobi and i'm not denied it but putting him behind sasuke and naruto is we're in way over our heads.
1- Lee - if this guy has his gates on, he's fucking unbeatable. His top notch speed, strength, and stamina make him a worthy opponent.
2- Sasuke - his sharingan and ninjutsu are quite helpful in battle, but he has wits and guts which makes him a fearless opponent.
3- Neji- his byakugan can view eveything in a 360 view. If he can take down the chakra points more faster without any disruptions, then he'd be crazy.
4- shikamaru - his intelligence and strategies abilities in battle withstands everything else.
Right now the rankings would go like this
The huge gap
3. Shikamaru (at one time I would have put jonin Neji #3, but he has done so little in Shippuden, it would be hard to justify that ranking. I think Kishi sees Shika and Sakura as the next two top former genin, but I just can't put Sakura high.)
6. Rock Lee
9. Sakura (she should be much higher, but Kishi has ignored her development)
13. Kiba (All the girls have accomplished more than him in Shippuden. Look at what Ino has done compared to him. He has become a comedic character. And I say this as a Kiba fan)
I'd say it's nearly impossible to compile any list on the rookies. Obviously Naruto tops, and Sasuke takes the second spot, but beyond that everyone else has been ignored almost entirely. With the exception of one or two panels, we haven't seen anything from the rookies in years. I guess one could group Neji, Shino, Sai, Lee, and Chouji together in terms of combat ability, behind the two monsters on top. They've each shown talent in battle, but ranking amongst this lot might be difficult. Shikamaru is stand alone because his ability is mainly his intelligence, which is difficult to quantify. Sakura could end up virtually anywhere in this list depending on the situation, although by now she should by all rights be an absolute beast, but alas it's not something we've seen from her. Hinata and Kiba are probably around the same level, and would be behind everyone previously mentioned. Ino has shown herself to be useful, but she is still limited by the requirements for her techniques to be effective. Tenten, is unfortunately just, I don't even know. I'm not sure why Tenten was even created, I'm honestly surprised that she hasn't been killed off by now. Kishi hasn't done much with his female characters, but I think he has to be punishing her by allowing her to carry on her pitiful existence, she has since her introduction been that random girl that absolutely no one cares about. But if I'm being fair she should be a match for Ino, since Ino's primary function is team support.
Sai, lee, Choji, neji and shino can rape him all the way. His amazing IQ and his shadow can't protect him from getting killed. Shikamaru is just an amazing strategist. But in one on one fight with his fellow rookies, he can't win to the characters I mentioned.
