Whether or not the seraphim stay with or betray the world government the ones in egghead coincidentally seem like perfect matchups for the monster trio. With them already clashing multiple times in the arc as is
- Luffy vs s-bear: kuma being a buccaneer, a believer of nika, believer of luffy, tied to dragon, and fruit being called the hands of liberation
