>>30946637>How do you explain the Cosmog line not having 570 BSTOther anon got the Beast Boost part, which also goes for Necrozma, but as for the 570 BST: none of the others, or Necrozma, evolve either. The Cosmog line can easily be explained by being some sort of special brand of Ultra Beast. They also make the portals to the Ultra Dimension and at least the one you get post-game is "born" in the Pokemon Dimension itself. Given the legends you read at the library, it's likely Nebby was as well.
The Cosmog line itself is already pretty unique either way, so it's not really much of a problem that they don't fit the BST of the others. They do fit the weird cry sound and the Prime Number theme. Necrozma does as well, despite also not fitting the BST of either the Cosmog line or the Ultra Beasts (it has 600 instead of 580 or 570). I'm not really sure what would explain the discrepancy, but there's enough in common anyway to provoke speculation.
