BonBon seems to not have a crew anymore. In the shorts BonBon was alone. plus he in Impel down. His crew would be disbanded coz they have no captain.
Also i can have a ray of hope right :D but hey luffy could release Croc and vs him again..

I've said this on another forums but i want BonBon, or Mr 2, the okama to join. Perfect time for he/she to. Bonbon is at Impel down, so Luffy can rescue BonBon and we can have an okama join.

I think Persona is stronger than Hanopp. Anyways, Hancock, Persona, BonBon= These 3 will join i hope.
