Zoro, Sanji, and the others will show impressive feats and win their battles But will be weakened. They will advance on Kaido. However to no avail, or forced from interrupting, or they end up losing. Luffy in time will battle Kaido in an epic battle. Kaido's Devil Fruit is (3 headed Cerberus) The middle head having the horns.However still having a humaniod body but with wings. Luffy will be killed and Law uses a surgery to bring the dead back to life. (but will cost him his life. Not Perpetual Youth surgery.) Luffy Will fight Kaido (using a new form) but it will be a stalemate. Blackbeard then makes an appearence and steals Kaido's zoan.He then has the strongest Paramecia, Logia, and Zoan. He will destroy Luffy's fleet in Wano. As a clue when Teach said, "An Emperor? It's still not your time Strawhat." He will Lose his Yonko status and thought dead. (Although it might be that point instead where Law will bring a dead Luffy back to life)
