Being able to fight for 2000 years with very little, albeit it some break is a stamina feat far beyond going 5 days straight. Xiao’s had to face threats to Liyue comparable to or superior to Haishan, and it’s battle against the people of Liyue such as Beidou lasted days on end
He fought for 2000 years with little rest and it isn't on his stamina section?? I mean I believe you. I've got little to no knowledge about Genshin, but that's astronomical and should be mentioned. Barely anyone's outlasting this man if that's legit.
Xiao has a crap ton of ways he can avoid the detonation we’ve already talked about, not only is the circumstances of its activation something Xiao would recognise and only fall prey to once, but he has shields and teleportation to keep him safe, even if he didn’t react, he could have the shield set up in advance of going melee, which just makes sense anyways
Think is, the detonation is one of many hits that would just damage Xiao if he falls for it once. Also Zoro states if he hadn't put up his busoshoku he'd have been done for, implying the detonation ability has higher AP than his usual attacks.
Unless Xiao precogs it then he's got little choice but to tank the detonation on that first time, which would heavily damage him. The issue isn't not falling for it more than once, it's how badly it would damage him if he does fall for it even once.
Xiao has superior stamina, tricky defensive options and has enough amps of his own to not be simply overwhelmed by someone else’s. He can corrupt and damage souls and he has the perfect toolkit to play a careful, defensive game and avoid taking too many blows, giving him the win.
And King has repeatedly shown the preference for ranged combat. That and he actively BFR'D Zoro like 3 times, meaning almost any attack from his imperial arrow might just BFR Xiao in one hit (unless Xiao's LS is high enough).
The issue with King is he can "sense the danger and threat" his enemies can pose, which is why he knew better than to let COC Infusion Zoro hit him even during his fire-on mode. He's not RECKLESS by any means, and he wouldn't let Xiao drag him into a losing game if that's what H2H implies. The battle takes place near a volcano too- if King BFR'S him in the wrong direction Xiao is taking a magma bath.
Staying at a distance, spamming slings and arrows as well as Danmaku slashes and pressuring Xiao with Deep Pride Stake (both to either hit him OR destroy the environment around him) would put Xiao on the backfoot constantly.
Not to mention King is so quick he can literally BFR Zoro, fly (kilometers) half a circle around him, intercept him mid-flight and BFR him BACK onto the field. The guy can literally STACK BFR.
King's haki negs elemental intangibility, his sword can latch onto Xiao's spear and disarm him with UNGODLY ease (peak human vs class G/T). His zoan self can heal from cuts, bruises, deep slashes, piercings, burning- you name it, within seconds. This isn't to forget the fact that King scales to guys with 5 days worth of combat without accounting for his Zoan DF, which is ALL ABOUT ENDURANCE and in the canon sets the users on a whole different level compared to the common combatants in terms of stamina. King resists the madness manip of Xiao's aura (a far weaker Luffy kept his sanity after taking 100 shadows, when even 3/4 can drive you mad), and has resistance to soul manip as well.
Xiao isn't resisting King's fire temperature or his imperial dragon flames, nor is he clashing with King without losing his blade or getting tossed literally miles away. He's got a lot of tricks, but King is just vastly superior in head-on combat and has crazy mobility/resistance
I can see Xiao taking it, but no way am I saying he's going over 30 wins if it was out of a 100.
My vote definitely stays for King. He's a pressure monster.
Even I forgot how strong this mf is until I'm now re-reading his fights
Alternatively Xiao learns Pteranodon facts because King likes sharing that for some reason
