if theres a battle royale im sure it will involve the vinsmoke family and the underworld emperors fighting along side Luffy. I believe this underworld emperors will become an addition to the straw hat grand fleet.

I believe Big Mom has enough manpower to match that number of people.

6 underworld emperors, 5 vinsmokes, 7 from luffys group + Bege
