I made this to see what people would choose. But like I said, I'm choosing Kaido and Whitebeard because of their insane endurance, stamina, and durability that would make them last longer in battle. All of these characters haki lvl mastery is near each others in some way and can compete with each other high-extreme diff at best. But Kaido and Whitebeard's insane physical abilities, two powerful devil fruits, and mastery over every advanced form of haki honestly tells me they would win. Whitebeard is only human, but he's no ordinary human compared to Roger and Shanks. Kaido is a literal giant already putting him above the average human. Its only worse considering he has (or had) what it took to rival both Roger and Whitebeard in prime. The only thing going for Roger and Shanks is their lvl of haki mastery and stamina.

Roger > Whitebeard

Shanks > Kaido

@SageJaystar Nah. I got Whitebeard over Roger and Kaido is over Shanks. But all are equal with one another as well.

I mean Roger is King of the Pirates for a reason, he doesn't need a devil fruit to be strong like Whitebeard.

And Kaido got clapped by Luffy who gets clapped by Shanks

WB = Roger

Kaido ? Shanks

Shanks has very little to actually use as evidence for what he can do. He only clashed with WB, had Kaido turn around, and one shotted Kidd and Killer. Neither of which are on the same tier as Kaido or WB.

So personally I think this is an unanswerable question given the evidence we currently have.

Be frl

If they all go brainlessly against each other, probably Kaido and Whitebeard. Since Roger and Whitebeard has been shown tied (4 days straight), I'm even giving this to Kaido over Shanks.

But if not fighting all brainlessly, combined with Shanks' pre-war, mid-war, and post-war negotiation skills, probably Shanks and Roger. We've been told Shanks intercepted Kaido. Combined with what we know of Kaido as a character, this is definitely huge feat, even if it's pure talk. Anyone needs enough bargaining chips in order to be capable of successful negotiation. That's why Kaido is so obsessed with his underworld business. But in the end, Shanks had the upper hand regardless.

So comes down to under which conditions you want to compare them against each other.

Kaido > Shanks

Primebeard > Roger

I have to go with WB and Kaido because the only thing we know about shanks is that he's the world's 2nd strongest swordsman.

Rockstar D. Charys its easy to understand. prime whitebeard = prime roger, so they get cancelled like algebraic terms. Kaido and shanks are left and kaido is easily stronger
