Believe me I'm admiral supporter through and through...
but portrayl here is different... Momonosuke's words alone is enough... Yamato and Scabbards also do not give Greenbull the same amount of fear as they did with Kaido
Portrayl regardless of "this happened to Kaido too or not" is different by miles
With kaido, they are all ganging on Kaido and would ask Luffy and co and all alliance to gang on him
With Greenbull... Kinemon and co didn't even want Luffy to stop his celebration... Yamato acted like they would handle him and wouldn't let him disturb Luffy... Momo didn't want Yamato to interefere in his clash with him
Do you realize the difference? With Kaido they all were attacking together and still it they got outclassed completely
C'mon... they all can sense the presence and haki of someone to recognize their strength... Kidd/Hawkins/Apoo shit their pants the first time they saw kaido... although Apoo had a hand in it... but Kidd and others first time saw him and they legit got intimidated immediately
This is what people don't understand about Yonko vs Admirals. Admirals are strong no doubt about it, but the portrayal is different, that's why most people put Yonko>Admirals.
1. When the Yonko clash they split the skies, that's a statement of will power, when Admirals clash they can do a lot of damage, change the weather on the island etc. But they don't have the same portrayal from Oda.
2. In order to recruit a pirate in your crew you have to earn their respect, while Admirals serve under the celestial dragons, and get disrespected by goroseis on daily basis.
3. When Emperors meet the goroseis sweet in fear, when Aokiji joined Blackbeard's crew the goroseis were simply annoyed, no fear whatsoever.
4. Usually (with exception of Buggy since he's a running Joke) In order to become an Emperor you have to take them down, but when the Marines needed new Admirals Oda just pulled them out of his ass.
Again, the Admirals are definitely strong, but the portrayal is fucking different.
