so what became of all the alchemy stuff? Just a red herring?

Just like the norse mythology theme of the Gen 6 legends, it's just kind of a flavor thing that doesn't get explicitly pointed out.

alchemy? explain

The cover trio are based on the three goals of alchemy (transmutation of metal, creation of life, and discovery of the 5th element), which were tied symbolic to the sun, moon, and aether, respectively. It pops up a few other places in the game too, like Type: Null and the Aether Foundation. (supposedly the Ultra Beasts can be tied to the cycle of rebirth, too)

It's just a neat recurring theme in the generation. There's really no meaning to it beyond that.

The better theory is reflection/emission/refraction with necrozma as the refraction member of the trio. Also fits the 'rainbow' motif and 7 trials /7 colors / 7th gen thing better. I'm willing to bet we will get Necrozma plot ans new form as DLC in not too long given how fast they revealed it

You mean soul (sun), spirit (moon) and body (cube)

The cover legendaries have had multiple themes going on since gen 4. (Time, Space, Anti-matter, and Solid, Liquid, Gas)

>still shoehorning Zygarde in after Necrozma's reveal
But yeah, Soul, Spirit, Body are also connected thematically with the goals of alchemy. Here's another pre-release theory about it.

>>29908008
The "cube" is just how they drew aether, since they had no idea what it was supposed to look like. It's never portrayed as a cube anywhere else.

At one time Aether was believed to be a type of otherworldly black light-absorbing matter that you were seeing if you looked up to the sky at night.

It became Alolan Muk's HA.
