Hay guys,I think if big mon forced one of her daughters to marry luffy, she would become allied another strong group (revolutionary army, dragon). At that time she can defect easily other yonko with the power of world noble (germa 66) and revolutionaries (dragon) and become pirate king.
Germa 66, revolutionaries and big mom,all have their different goals.
How do you think guys?it will happen?
Sorry for bad in english
