Ok?
Idk what the point of that was lol.
We know Kidd injured a SC before, we dont know who but I'm guessing either Snack so thats why Urouge got the win and its the easiest/most covenient one for Oda to write, especially as Snack as non-existent pretty much and easier to downplay/write off or it was Smoothie, like the theories Kidd took out her eye and thats why she keeps it covered with her hair.
Could also be Cracker with the scar he has and hes that kind of psychotic opponent who would be great vs Kidd, but I doubt Kidd was able to get past his Biscuit Soldiers, especially since he didnt even use Haki vs Kaido and thus I doubt he has Haki emission and such too.
Cracker would only get that scar from Kidd if Kidd faced his true self somehow, so either Cracker was not in his biscuit soldiers somehow or they actually forced him out somehow from them?
Oh wait...Killer injured Kaido internally with his sonic attacks, granted it just hurt him and didn't do any real damage as in shredding his insides or so but maybe it could have bypassed Crackers soldiers defences and injured the real Cracker inside?
Idk though, Oda doesnt seem to care to show/tell us what happened. We still dont know even know what happened with Kidd vs Shanks ffs.
We got nothing on it despite Kidd fighting Big Mom of all people too, sigh.
