How will this guy be a challenge to luffy?
When he is clearly not even on the same level as kaido and bigmom. He even had hard time defeating law who's all devil fruit guy since we know bb can nullify df ability but he still had difficulty beating law. And he showed no extraordinary haki, he might not even have coc. And he is being setup to fight shanks since marineford. How would he even stand a chance against advance coc users?
