This guy claims BB don't have CoC because its ''not confirmed'' yet
-Then he says Imu, (who can even be a princess that Luffy needs to save) let alone confirmed to have any type of Haki yet.

Also Superior Ad.CoC > Superior DF awakening is invalid for BB because he has 2 superior DF awakening not just 1.
Oda showed us 2 DF awakening users Kid + Law winning vs. Superior CoC user Big mom for that reason.
Even if BB doesn't have Ad.CoC (which he could have easily no one said he doesn't have it) he can still have ad.CoA + Superior physical strength + Gura which can easily overpower any Ad.CoC.
