Dude… Kaido didn’t use any of his serious moves. Big mom didn’t use any of her serious moves.
Zoro didn’t fight Kaido in this final fight. it’s luffy vs kaido as the final fight. Like saying the rooftop fight was serious is ridiculous when Kaido didn’t use any of his drunken forms, or his big fire dragon he’s using as his finisher in this fight.
Rooftop 5 vs Big Mom and Kaido is nothing compared to kaido vs Luffy.
but if you think both parties were super serious:
Why didn’t law and kid use their awakening?
Why didn’t Big Mom use her bigger mom power?
Why didn’t Kaido use his drunken forms?
Why didn’t Kaido use future sight?
Why didn’t Kaido use his fire dragon?
The only people who went all out on the roof were Zoro Luffy and Killer
Just because your not using your finishers doesnt mean your not fighting seriously!
When Luffy was only using G2+3 and Kaido was using his drunken forms does that mean Kaido was seriously and Luffy didnt take all out Kaido seriously to you?
What fight did Zoro fight Kaido is, the filler chapters with 2 yonko vs 5SN then?
Yeah rooftop fights where not serious even though both parties were trying to kill each other, but nah to you Sanji fans it was filler were no one was trying at all and were just fooling around even when Kaido thought he finaly killed Luffy it was just him fooling around since he wasnt serious...........................
5SN vs 2yonko was far better fight than Luffy vs Kaido
Let me sum up your confusion into one statement/question
Why in One Piece does no one ever go for their finisher from the get go even in a life and death battle?
After understanding that question you wont ask stupid questions ever again!
Killer went all out on the roof???????when?
