Coby definitely has CoC he has the ambition and determination. He knew was weaker than the average nd decided to train twice as much if not more to make up for it. He is setup to be what a Marine should dream and esteem to be. He is also set up to smash Akainus daughter as well 😂 Anyways I wouldn't be surprised if he is set up to fight kuzan but maybe with help of another character.
