What? Where did Hawkins heal Kid? All he does was cutting the connection, thats why kid felt free. There was no healing since beginning of the raid, not even a small pause.
His CoA was enought to significantly hurt big mum, made her being, she felt the urge to cut down the bull before reaching her, while other attacks where openly taken.
His CoC was strong enough to be acknowledged by Kaido himself.
Additionally he fought Pre-Wano Kaido already and didn’t (!) got oneshotted, like Luffy pre-udon got. Kid fought Kaido for some longer time, mentioned by Hawkins. It is save to say Kid was pre-udon stronger than luffy.
