Definetly but Katakuri wouldn't need to defeat him in 15 Minutes. He can fight for 10+ hours which gives him room to land waay more hits than Zoro and Sanji did.
I am not even saying that Katakuri is stronger than King because I don't believe that. But "ANCIENT ZOAN DURABILITY" is just bullshit.
Why? Because King and Queen lost to
vastly superior opponents respectively in 15 minutes?
Pray tell me, are you going to argue that Fujitora/Kizaru/Ryokogyu have less endurance than Akainu and Aokiji when they eventually lose to Sanji and Zoro within a day?
That's litearlly not how it works lol.
Jack, an inferior Ancient Zoan, lasted 5 days against
his equals in the base Dukes. Katakuri laster 11 hours against
his equal in Luffy.
King and Queen are superior Ancient Zoans than Jack, they'll be able to replicate similar endurance feats against
their equals. They lost under 15 minutes because Zoro and Sanji hit really hard and
outclass their respective opponents, unlike WCI Luffy and Katakuri.
