>>50585437pokemon is a franchise so big for 20+ years
people between 15 and 35 had their sexual awakening when the anime, games and all the other things were around
Pokémon had a consistently human-like and well proportioned characters and also gave most of them a very unique style and traits
Despite how different they could be, all of them are good-looking despite age, race or anything
also all of them are always pretty happy (a trait people find unconsciously attractive)
Some people of this demographic, grew up to become great drawers or artists in general
Some of them draw even more material of those characters, giving them not only different body types or characteristics but sometimes also more deep background or personality traits
I wouldn't wanna fuck Lana if it wasn't because of his anime personality
Many Serenafags share the same reason
Dawn has a pretty good clothing choices that also embrace the her but (or so think the hentai artists)
Mallow is always depicted as a tanned, cheerful and with a quite developed and well proportioned body in games and other media
But if I liked furry or guys, Alain, Gary, Braixen, Gardevoir, Lucario...
