I told people don't fall for the typical introducing a character hype. First panel is always "only" hype.
GB defeating King and Queen was only just "introduce a character hype" no feat at all.
So from this chapter on things or going to be balanced in a realistic way.
Aramaki should be strong, but Oda separated him in purpose from Luffy, Zoro, Kid, Law, Killer, because the would defeat him in no time.
