Harald was played as Xebecs exact equal as more then anyone else in the flashback...?
The one he had a legendary clash with, hyped by the narrator
The one Xebec really respected, and wanted to partner up with equally, not even just join his crew. Xebec didn´t care about his crews infighting or not disrespecting him, but he personally kicked Kaido for saying they should use dirty tactics against Harald
Gorosei want Harald to kill Xebec, they have a fight while both mentally nerfed
Xebec tells Harald his real name, I would say paralleling, but it´s pretty much an exact reference to Roja telling his name to his equal WB
Xebec literally got especially pissed at Imcel saying he wants to take control of the giants, more then when Imcel was talking about wiping out his clan, which includes his wife and son..... This is literally Naruto level of gay bromance.
What did Xebec really have with Garp and Roja in comparison?
I agree Harald is a top tier as strong as Xebec/Garp/Roger in the flashback. But my question was why it's silly to not have Xebec as the top guy.
Harald-Xebec was focused on more since the flashback is mostly Harald-centric. The conflict of Roger-Xebec is voided, along with any interactions that happened between Garp-Xebec.
With Roger it's already implied they had met up with each other numerous times.
It's pretty clear from the below panel, Roger-Rocks were the two top dogs on the seas for piracy.
The narrator in the same flashback makes sure to remind the reader who the one that stands atop of the pirate world is. It's not like Roger was sitting on his ass doing nothing while Rocks and them were running around causing destruction. Blud became the 1st person in 800 years to reach lodestar, the 1st and only to ever do it even a decade later by the time of Oden flashback.
With Garp it's pretty clear that Xebec-Garp even before God Valley had gone against each other multiple times to the point Xebec was familiar with Garp's inner thinkings/ideology. Along with Garp actually showing active care about Rocks during their fight from being the 1st to ask Rocks about undoing his curse rather than just straight up whooping on him. To then being the one to go out of his way to comfort Xebec's feelings he was going through at that time.
While Harald-Xebec were friends on great terms with each other. It's made pretty clear to the readers multiple times in the flashback that Roger-Garp-Xebec have great deep connections with each other as enemies and have interacted with each other multiple times. His connection with Harald is given prominence since it's about how Harald was effected by Xebec. Showing casing Roger-Xebec-Garp interacting over the course of that flashback multiple times would've just increased the length of the flashback and took the focus off Harald, which God Valley did for few chapters.
And of course the below panel makes it clear who the 3-man dawgs from that era are. Harald isn't one of them, just like Newgate/Sengoku/etc aren't.
But again, i'm not contending whether you have Xebec as top 1 or Harald as top 1. I'm asking why you think it's silly to not have Xebec as top of the verse, when he's not cemented above Roger or Garp.
