Someone like you doesn't deserve decency.
-The satisfactory King the Wildfire who caused zero wildfires.
-The satisfactory leather suit that could have been fireproof but was just hiding his appearance because Lunarians are pursued (and this guy wanted to change the world...?).
-The satisfactory fallen angel-looking race capable of generating fire that ended up looking like your average winged with a tiny flame on the back (because the suit being fireproof since Lunarias are engulfed by flames was too difficult to portray, I guess).
-The satisfactory invulnerability that could have been explained by cauterization with fire, or the ability to extremely regulate his blood temperature, or whatever yet what Oda came with was "somehow this fire makes him more durable, but without it he gets faster because I don't feel like explaining it".
-The satisfactory inventiveness of Zoro's way to defeat him: "So I'll just attack him while he has no fire because I shouldn't face any trouble at hitting him at higher speed" (because Oda certainly couldn't think of anything to slow him down, such as Zoro destroying the environment in order to make him dodge while flying; or whatever).
-The satisfactory handling of Zoro learning Kin'emon's fire technique out of the blue even though Oda actually planned on putting him against an enemy that can generate and control fire.
-Of course, Zoro can indeed damage him even while on fire because of his conqueror's coating, I assume. If Oda is going to fall in the middle of nowhere with this (he can hurt him because he can land on his non-fire form, but also while defending with flames), why not focus on what resolution? Even turn Zoro into a full wild beast in order to contrast his Bonez fight and resume the "anything goes" theme from the start of their fight.
-Oh, and King can generate explosions by being stabbed but why elaborate on this.
Do you want me to talk about Queen's satisfactory versus too?
