>>50823226Everyone in this thread are all off the mark. The real reason why it has all this porn is because Umbreon is the easiest one to self-insert as PROVIDED you have the mindset of an immature teenage boy. Y'know, the ones who get all emotional and hyper-defensive by being compared to something girly/gay and who absolutely NEED to feel DEFINITELY MANLY AND NOT AT ALL GAY D:< by associating only with boyish things. It's retarded but a lot of (not most) guys are like that.
And for FURRIES the ones drawing Eevee porn, well they're a bunch of neurotic outcast insecure people. Incels. They clearly have much higher rates of these narcissistic, machoistic douchebag types. Exactly the kind of guys who throw a fucking tantrum if something feminine is in any way associated with them. They want to fuck the Eevee family because they are mostly girly and are exotic animals. So if they want self-insert porn where they can imagine themselves raping cats or whatever, they need to use the most DEFINITELY NOT GAY I SWEAR Eeveelution.
Let's see.....
>all Eevos from gens 4 and 6, + Espeon All very blatantly too feminine/gay for them.
>gen I trioFlareon could have been more popular for this, but it's fluffy and these guys don't want to self-insert as something fluffy. Jolteon is arguably the most boyish after Umbreon but the spikes are just uncomfortable enough that self-inserting can feel awkward. Vaporeon is fine I guess but it isn't a MALE power fantasy to want to be a mermaid.
That leaves ONLY Umbreon, whose edgy coolness and lack of any obvious femininity makes it the perfect pic to draw pictures of giving dick to all the other Eevees. It's black, which radiates power and dominance. Red eyes with slits and Dark Typing imply violence or at LEAST rebelliousness. So to answer your question finally OP, Umbreon has so much porn because it's the only one that hits all the right notes to serve the role as an insecure male self-insert power fantasy.
