Ugh...unless we are seeing how Jinbei escaped too, seeing Germa 66 seems like a waste of time. Germa 66 levels of technology are not all that advanced since Queen can do more complex things.
So we have a potentially new type of haki since Oda is having a new visualization with Sanji's upgraded jambe attack.
Queen is going to be a part of a future arc, which is why he is going to be separate from the Onigashima chaos (he can escape to do whatever Vegapunk level of scientific contributions). Speaking of Vegapunk, with Vegapunk, Queen, and the rest of the moral scientists, why is Germa 66/Judge needed? The only purpose they serve is to have things with Sanji properly resolved. Petty Sanji having a moment of forgiveness would definitely be great, but I could easily see Oda continue the pettiness.
Ah...I wonder if the Wano Kuni arc is where both Sanji and Zoro find their wives! Oda has been excessively direct with Zoro and Hiyori, but tying in the kindness/friendship with a mouse was a nice recovery. Hopefully the collapsing is only a side effect of using all of his new powers.
Lunarian (or whatever the moon race with the flame abilities) probably is limited by concentration. The creation of flames is more complex than for example Electro by the Minks, so King presumably cannot use as much haki to defend if he is creating flames. But minions are expendable, so they were necessary to confirm the Government sees information on Lunarians worth 100 million beli (more than info on Ohara since Robin was only 81 million if I'm remembering correctly).
I wonder if King will be in an opposite role as Queen. The tall, dark, and handsome aspect seems completely opposite of Queen, but getting along with the Mugiwara opponent is a great indicator of coming up again in the future. Ah, so both Skypieans and Lunarians might be born with tattoos/it is a coming of age ritual.
Woah...young Kaidou looks quite different. But he's a beast since he's still fighting with kairouseki cuffs probably. And we get both King's name of Arber and the biggest trait of Lunarians being endurance. This matches Kaidou too since he's a beast too.
King being able to create magma levels of fire is key since this is the gap between Ace and Akainu (the best offensive fruit ability). I have no idea about the Buddhist reference on the "103 Emotions" (which is either the same reference or something similar as his "Pound Cannon" attacks), but we see Zoro gain two or potentially three new aspects. We have the Emotions aspect, Kinemon's fire/magma cutting, and the "Underworld King". This last one could just be the naming system of haoushoku haki infusion.
But we are definitely getting new visualizations of haki and this matches Zoro having different king names to associate with each.
Zoro presumably has enough haki to survive the fall onto the main island of Wano Kuni. But seeing as how King and Queen hate each other moreso than Zoro and Sanji, they will not help each other and will go their separate ways.
