Vegepunk can be worth like 5 billion because of his knowledge of the world government secrets, the possessions of an army of animals/robots that are ? powerful. Then he has himself with his 6 bodies with their own quirks which can easily be Commander level and him being equal to a top tier.
Oh yeah a cure for Ebisu Town would be dope because Oda hinted Vegepunk could had been in Wano.
But also Vegepunk with his knowledge could also know something about how to forge a black blade.
Oda using this arc to clean up some of Wano dropped plot lines.
My idea roaster to invade Beehive would be Luffy, Zoro, Nami, Usopp Sanji, Chopper and Robin. On the marine side we will have Smoker, Tashigi, and helmeppo. Possibly Hina if she with Smoker right now.
So what your roaster?
