Anime & Manga I have nightmares that Doflamingo will return with AdCoC and be yonko tier

That would be the biggest ass pull in op. Mingo is chained to a wall and can't even move. If anything he should get weaker than he was not stronger. By the point if he even escaped both Luffy and law should be far beyond what he was. I still think if he does escape him helping BB would be interesting not him being on par with kaido.
Hey now, as long as Luffy and Law gets stronger, you gotta bump Doffy up to Yonko level.
