So start scaling Buggy as a Yonko since portrayal means a lot.
When has Oda portrayed Buggy as seriously strong? The message we as readers have always been sent is that he's all facade; while the message we're sent about the Elders is that they are legit strong.
Luffy was the only one reacting to Kizaru like he never did before. And he gave 0 shit to all Gorosei.
He didn't give 0 shit, Luffy reacted to Saturn's coming too; although I don't see your point, you know I'm not saying anything about Kizaru in relation to the Elders, right?
Simply. It is an unknown haki in a scenario of battle. Nothing related to their strength.
It's explicitly stated to be a strong haki by Lucci and Jinbe described Mars' haki the same way he reacted to Shanks.
No dude. No one knows how strong Gorosei are. Very few can sense haki strength and even though they can't tell if the haki is stronger than theirs. Doflamingo only knew base Luffy haki was weak when he got hit by it and only knew G4 haki was stronger because got hit by it.
Yes, "dude". Lucci described their haki as strong and was scared by Mars. Jinbe described Mars haki as unreal ni the same way he described Shanks'. Whether the Elders are stronger or weaker than their first assessment, everybody here is aware that they are powerful.
Pretty much all Yonko but Teach got haki hyped like that.
Not at all. Tell me which Yonko has been hyped like this.
Big Mom was told to be unhurt when her haki is up. And Kaido got several death sentences and jumps off 10 thousand mile to the ground and doesn't die.
And none of them made Luffy run away because he found them to be immortal. Again, the difference in how Oda portrayed their immortality is abysmal. Saturn and Ju Peter are regenerating from deadly wounds, the five Elders haven't seemingly aged a day in decades, Bonney couldn't change Saturn's age and Luffy stated them to be immortal as they casually came back from an explosion (to which Dorry and Brogy reflected as they didn't know of any immortal race, further stressing the oddity).
Absolutely no other character's "immortality" has been explored like this. Luffy, Kid and Law didn't try to run away from Big Mom because they found her to be immortal, and in fact she is described as killable the same chapter she's told to be unhurtable. Kaidou was easily damaged by even the Scabbards and was hurt by the same Red Roc that Warcury no sold. I'm not saying the Elders are more powerful than an emperor or an admiral, I couldn't care less, but you're being dishonestly stubborn by denying how OBVIOUS these guys immortality is being portrayed.
