He didn't singlehandedly defeat them though. He defeated them with poison gas.
He was defeated by the Marines. He was presumed dead because of the beating he got.
Zu's trunk was aimed at the entirety of the ships , Jack was just collateral
Jack had reinforcements. We see some of those reinforcements weren't really defeated when they were commenting on the Scabbards v Kaido fight. The fact that he had reinforcements implies he didn't do it alone
- Yeah but he kept their game for 5 days and endured it, after those 5 days was his turn to use a tactic.. and even if evil, was a winning tactic. With those 5 days he showed his superiority against Inu/Neko in a 1v1
- By the Marines? You mean against Fujitora, right? Btw he obviously lost there, I'm not denying it. Still deserve to be mentioned for his huge balls
- Doesn't change the fact that he survived that smash, it not being aimed at him doesn't change the overwhelming force he had to endure
- Pretty sure the reinforcements were necessary to face the Minks who were resting, basically to ensure a stall between the 'minor' forces of both sides
