I think it depends on the evolution (which is dumb)

Oof, what a shame.

I mean I find it dumb considering kangaskhan, and other species are ok but other stages aren't no wonder people are going to itaku, inkbunny etc

Always was >:3

Oho, noice! :3

-final form evolutions only
-no single forms
-legendary/mythical are okay if it's bigger than the human (no mew, celebi, shaymin, lake spirits, etc)
-human males need facial hair to show they are old enough
-human females need size DD or larger busts to show they are old enough

That looks incredibly restrictive. :/
still, good to know.

Never went out of style.

Wonderful! :p
