ALLEGATION: Early Jinbe and later Corrida Colosseum's Host alleged Blackbeard is a Yonko now.

PENDING: However, 'Yonko' was defined by a stalemate of four stronger pirates in the New World. And we don't know whether Blackbeard is stuck in the New World or not. Maybe he can be planning/starting another attack against another  Yonko: one fallen, three standing.
