One Of The Last Real Ones To Do It
They are both captains of their own crews, I'd actually like Bart to be a Strawhat but I don't know how well the groupie gimmick if he becomes an actual member.
it would probably become a running gag with some potential for story use eventually like sanji nosebleeds or Zoro getting lost, or Usopp being a coward and then manning up. Realistically his shield would make him really valuable how many times is the sunny going to get high jacked while the crew is on an adventure? Especially as they start facing more guys who can one shot the ship from a distance..... Barto powers while OP is likely the only thing that will justify certain characters from just fukking the sunny up as soon as it reaches a dock.
