Blackbeard, high - extreme diff. I think BB wins because he survived a quake bubble from Old WB, a slash from his naginata, MF Sengoku's shockwave and 2v1'd Old Garp & MF Sengoku briefly and came out fairly well.

@IKTime You know well you need a two sentence comment with your own opinion. You've been here for awhile now my guy. XD But Kaido got this imo. I was stumbled on this one ngl, but Kaido in his full dragon form can use air slash attacks and is very agile in this form and has some pretty powerful attacks in his full dragon form. Question is, does Blackbeard's Yami Yami still work in the scenario? Bc if BB manages to deactivate Kaido's DF power, than BB would be setting himself up since most of Kaido's strongest attacks are in his base and hybrid form and MF BB def ain't withstanding any of his most powerful attacks.

Keep forgetting. Editing my message after I send this. BB probably could withstand or at least survive the attacks considering the fact that he took a Gura-Gura punch from WB, a slash from his naginata, Sengoku's shockwave and fought Sengoku & Garp briefly simultaneously and came out from MF fairly well.

Yeah but those attacks are not named and are from characters out of their prime.

Black Beard is not that strong .

I doubt he even has observation haki .

He does have Observation Haki

It does not show he heas observation haki
