The new policy is... dumb.

There's a number of pokemon, including series mascots, designed to have young proportions by their very nature. They ARE meant to appeal to the younger people. That is how, as kids, we all fell in love with them when we were at that age. And just "Aging them up" is a lot harder than it seems. Especially if you want to keep that cute aesthetic.

And also, take a look at most real world pets. Even when they're in their senior years they still look really cute and childlike. It's how these creatures have evolved, or been bred in some cases because of how humans have selectively bred them.

Now I do not know what I will be doing with regards to all my stories and artwork but I will make this statement.

ALL characters depicted in my stories and artwork are over 18 years of age, regardless of their species.
