I know you're tired after work man but at least hit me with something more creative.
Okay
Big Mom is less durable than Kaido
Big Mom was shitting her pants when Zoro flexed his Haki
Big Mom needed Haki to block an attack that Kaido no sold to face
Tatsumaki can damage Kaido
Tatsumaki would damage Big Mom even more since she's less durable durable Kaido
King can't be damaged by Tatsumaki
Hence King is more durable than Kaido and a lot more durable than Big Mom
King is clearly much faster than Big Mom, her CoO was unable to stop King on time
King hits harder too, Hakai double Big Moms max strength couldn't send Zoro flying but King with his wing sent zoro flying
King is physically stronger too
Marco was equal to serious Big Mom
Marco is weaker physically than Base King
Hybrid King is much stronger than base King based on his performance with Zoro
Overall King high diffs Big Mom
Blame Oda not me
He made King look better against Zoro than two Yonko.
