Says zoan awakening changes your personality and makes your mind weaker, kaido stayed the same the whole time while Luffy turning extra goofy and stupid is explained by his zoan
This makes me think that the Drunk Modes at some point were meant to be Awakening stuff with the change of personality, maybe even being Kaido's own way to access it. Just like Chopper using a modified drug (Rumble Ball) to change appearances and access a Beastly form with weak control over your actions that looks eerily similar to the Impel Down guards. Hell, ALCOHOL IS A FUCKING DRUG, IT COULD HAVE SERVED THE SAME FUNCTION.
And then Oda fucked it up because Drunk modes stayed for 2 chapters, and Kaido never stated anything about Awakening during that nor showed anything even remotely close to losing control over his actions or mind.
Jesus Christ Oda had all the pieces and then fumbled it for a giant fire dragon.
