You can't compare random or fodder giants to Giant Butterfly Mode Choji. Choji would wreck most giant characters in One Piece. Who has the Weakling Trio defeated that's "way stronger" than GBM Choji? And I'm just talking about him alone. With the help of hax'd Ino and genius Shikamaru, Choji stomps the Weakling Trio
Nah, Choji's best feat that I can remember is only
this. When fodder giants of One Piece can do things like
this, and
killed Sea Kings as big as a island. A fodder gigant has the techiques of Elbaf, Choji don't have a chance against them.
Now, there are a lot of characters stronger than Choji. I mean, Pre-TS Luffy can one-shot him and Usopp was able to tank some punchs of him, and even predict some of his attacks. I mean, you are understimating them, they fight against characters that are physical stronger than them all the time. They are also very smart fighters. They have a perfect coordination, you only have to see how Usopp is able to use his pop green to
create gigant explosions underground and then Chopper react to help him without even communication.
Shadow control? Ok, but that has a limit. Shikamaru's jutsu is very weak if we compare it with Moria's devil fruit. And they always learn
about their old fights.
Usopp also has a lot of Pop Greens that can keep him safe against an physical fighter like Choji (
1,
2,
3,
4). I mean, Usopp's pop greens can
defeat beast that be
as big as ships and
metal. And all his abilities can be used to support Nami and Chopper. And, if you forget it, he is a large distance sniper, maybe Shikamaru or Ino can try to control them, but that jutsus let them in danger and if Usopp don't attack, then Nami or Chopper can do it. Usopp esaily can be
far away and support his crewmates. Anyway, he is the most versatile warrior in this versus, his pop greens can have a lot of uses.
And to be honest, Chopper is enough fast (and have also some variations of his power points) to dodge any attack from Choji or Shikamaru (even underground) and attack them if they try to control Nami or Usopp. Also, there is a 4th fighter in the mugiwara's side, Zeus. With his help, Nami easily can one-shot any of the Ino-Shika-Cho trio (or even all the trio) if they aren't enough fast to
dodge this attack. Now, this is not all in Nami's side. Zeus is now loyal to her, and only Nami is able to feed him with deliscious cloud balls so even if Ino or Shikamaru try to control her (or Chopper/Usopp) he
would attack them with fury.
As you can see, the Ino's and Shikamaur's control don't would stop them. Even I thing that try to control them can be counterproductive because they would end in danger and one debility and Nami or Chopper can one-shot them anyway. Even they physicals fighters (Chopper and Choji) have a high difference between them.
While Choji is only able to use a huge brute power, Chopper is smarter and have a higher versality in combat. If he need it, he can be faster, stronger, more durable and also found his debility with his power points.
I mean... Forget it. Nami can one-shot them if Chopper and Usopp work as support for her, Usopp as a large distance fighter and Chopper as a close combat duelist. Even if they dodge one of Nami's attack,
Zeus can redirect his attack in any moment.
