It should be a blessing for Sanji to fight someone as strong as Sir Crocodile lmfao.
You ain’t ready for what awakened Crocodile is going to be able to do.
I'm a real Sanji fan, I care more about stuff like thematic ties & narrative importance for Sanji's opponent, which Crocodile does & fits well. There is indeed depth & value for him to be Sanji's next opponent.
I can also see the extend of how threatening Croc's Logia power is gonna be.
- Logia's awakening, no need to say more. It's narratively important if Sanji's fight is the one to first showcase this.
- Logia's intangibility is a good trigger for Sanji's Future Sight.
- That dehydrating power is a good way to test the limit of Exoskeleton.
- His "mystery" of changing gender is also fitting with Sanji's character.
- Croc himself have a super strong tie with Mr Prince, the one who foils his Arabasta plans.
In summary? I understand Sanji, and I also understand Crocodile's power.
My problem? Is how big Oda gonna power boost Crocodile (himself, not the DF) just to be a struggle for post-Wano Sanji. It's definitely gonna be top 3 biggest upgrade not far from Luffy's, which at the end of the day, possible but highly unrealistic & less believable.
I have nothing against Croc, I have something against how big of a power boost he will get.
