The golden part here is not that Momo hurt Kaido, at this point anything and everything can, but the fact that Momo managed to dodge Kaido's attack. Even if let's say Luffy saw the future and warned Momo about the incoming attack, but the fact that Momo had the speed and the reaction to avoid an Emperor attack is nuts, it's just nuts.
Kaido takes his time when he wants to charge his boro breathe lol
Thunder bagua on other hand… if he dodged that… I would die from laughing
