Pirate Warriors 4 came out a while ago, and in it they have a Non-Canon Wano story. Where Luffy and the Strawhats defeat Kaido. The Story itself is Non-Canon but as you "Level Up" characters and unlock their Attacks and abilities they seem to follow the Canon of the Manga.
After defeating Kaido you unlock the Attack " Dragon Culverin" This attack can only be Used in his Gear 4 form. and is seemingly his most powerful single attack. Could this be the Finishing Attack that defeats Kaido?
