NSFW of commonly know/well liked Pokemon

>Art mostly ranges from above average to beautifully drawn.
>Creative OCs and complex ideas for many drawings.

NSFW of somewhat obscure Pokemon

>Most of said art okay but it's nothing compared to something like Charmeleon or even Furret
>Those that are good were mostly commissions or artists doing it for clout where said Pokemon got showcased in a Direct. aka: flash in a pan
>Worst of all, most art is either fetish shit (typically diapers or feet, pick your poison) or gooner art - which even that is few and far between...

Why does this happen? Don't tell me "the Pokemon is too niche" because even shit like Muk and Magcargo can do well in niches.
I just want my boy to be up there with Buizel and Riolu, is that too much for some artists?
