don't know what should I expect here.
It's like saying "Coby won't become a marine capable of doing something significant. Have you seen him? At best he Will be a normal marine fodder, his Dream Is to join marines and that's It"
World you have expect the Coby we saw at Ennies Lobby?
No One would and he was like a different Person and his Dream of becoming a marine switched to becoming a marine Admiral.
Did you expect this during that time? No One would have bet that Coby could become as strong as currently based on the Coby of First chapter.
Here same thing.
The same thing Will happen, Just like we saw a different and strong Coby and helmeppo with different appearance same Will happen in a prologue where they Will Clash with Luffy and Zoro this time not losing that easily.
