Being a Conqueror is something seen since childhood. You dont take shit from people and you fight back
Kid Sanji probably has the most consistent and best showings of incredibly strong will.
- After 2 years of abuse and imprisonment, his dream of becoming a cook and the All Blue never died. Instead of fearing his father who's a general of a clone army, he instead attempts to fight him for his freedom. Again this is after his abuse and imprisonment.
Attempts to fight and kill a renown Pirate and his entire Pirate crew. Reminder every adult on The Orbit cowered and were shook of the Cook Pirates. Sanji was the only one there ready to stand and fight.
- After starvation for nearly 3 months, he still has the strength and willpower to kill the Pirate Captain. Reminder he knows how strong Zeff...he felt his kick...however hes absoutely ready to do anything to survive.
Its absoutely ridiculous for Sanji not to develop Conquerors haki. He has the best showings of willpower at a young age even compared to current CoC user adults.
Again ambition is meaningless.....A Strong King is most likely a CoC user....but not all CoC users are Strong Kings. Not all CoC users want to be leaders....however that doesnt mean they wouldnt be great leaders. Sanji showed countless times hes a great leader. And one of the strongest CoC users....had zero ambition (WB).
So yh Oda better not fudge up and not give Sanji CoC. The best moment for Sanji to show CoC is when showing the difference between him and the Vinsmoke kids. Vinsmoke Kids have no chance of CoC because Judge took their wills away from them....however not only will Sanji display haki, but the rarest one. To show isnt anything like them and Judge made a mistake. This could be in front of Vegapunk.
But still I want him to unlock it next arc....no one has time for the Vegapunk arc.
