Hold it for 1~2 second, almost died (as everyone there would die), if it wasn't for Law. Even Kidd thanked him for it, it was a sacrifice for the others to get out of the way. The attack heavily wrecked him in such a little amount of time, as expected
We don't know what is King's main fighting style, if Queen looks so versatile, King should be the same way. Zoro cutting fire may have or may have nothing to do with this.
And Enma was showcased on almost every chapter as a important part of Zoro's AP getting stronger and being slightly useful, and yet some you guys think it means nothing. He saved Luffy once against the Dragon Twister, an attack that did nothing to Luffy but suck him into Kaido's Dragon's mouth, and Kaido wasn't serious enough, thats why he couldn't do shit until Luffy runs out from Gear 4, then he goes Hybrid and start acknowledging the situation as "fun"
Good feat, more symbolic than anything, but it was his strongest attack, and he didn't bring Kaido down. During Oden vs Kaido is clear that Oden's first attack was strong as hell and did bring Kaido down for a instant, the scar he made is also much bigger, thats to the point of where Oden was ready to give a even stronger attack until he gets heavily distracted and hit in the head.
He didn't intercept nothing, his club is above him, Zoro didn't touched.
