>>42712367there's literally 1 (one) evolution line that originated in Go, and so far since has only been usable in a Kanto game.
I question whether you need an "etc" or any seperate group to exist for meltan/melmetal and why specifically lump it in with Galar. They're numbered in the natdex before Galar, so why not have them in an "Alola etc" which also might make more sense given UB being literally from another dimension.
