How to check if a "newly announced Pokémon" is real or a hoax: If there's no Japanese fanart of it on Pixiv within 5 minutes, it's fake.
LoL so true. Thank you, Bulbagarden!!
And the first image will have been drawn in about 50 seconds.
After 5 minutes you start getting the crazy high quality fanart.
I remember there being a lot of artwork for Cactowl though. :P
Come on, hoaxes can be fanarted as well!
