Even if I hate Orochi has character, he is a very great villian who doesn´t underestimate his enemies.
For the next chapter I expect a very equal battle, the confrontation with Oden vs Kaido offers so much and this time Oda don´t really need to nerf a villian/hero group to make the battle fair. Remember Whole Cake island, the alliance was quickly overwhelmed by Big mom and his force power. Oda need to nerf Big mom troup to let Luffy and co escape, this time he don´t need to nerf both sides. Oden is said to beeing a famious/legendary pirate in the new world and he became stronger after his travel with Whitebeard and Roger, in otherhand we have still the "young" Kaido who still grow up. The encounter can be very perfect, where we see both sides power and strenght. I hope Oda take 2-4Chapters alone for the confrontation and take his time to make it to a great end of the flashback.^^
