Sanji needs to beat a Gorosei by EoS. They all have CoC, yet Sanji doesn’t. How can Sanji possibly overcome a gorosei?
imo it will take several power ups to get him there. I think one of them will probably be a raid suit by Vegapunk, made a thread about that a while back.
But here I want to talk about another power up Sanji is likely to get. Imo, he will inevitably end up needing to do roids in order to boost his strength.
Sanji’s timeskip mentor was Ivankov. Unlike Mihawk and Rayleigh, Ivankov is no haki master. Yet he has one thing that those two don’t. Drugs.
Ivankov is a hormone man, hence he can make steroids. On a normal human, steroids allow the person to surpass the body mass they can naturally attain. However Sanji is not a normal human. His muscles are enhanced by germa genes, on top of the already super human body he had due to his training from Zeff and Iva.
Hence, were Sanji to do roids from Ivankov and reach surpass his own limits, I think it’s very likely he would have top tier strength, rivaling that of Garp or BM.
If he can have Iva harden his exoskeleton using hormones as well, then Sanji would be able to unlock the next level of his flames, as a harder exoskeleton means he can endure more heat.
So yeah, I’m guessing this power up, whenever Sanji gets it, will give him strength and durability comparable to BM and heat comparable to Akainu’s. Basically cheat coding him into the top tier.
