"Pokedex Entry: Venudrill, the Are-You-Freaking-Kidding-Me Pokemon.

As the flower on its back has evolved into a gross pair of freakish wings, Venudrill no longer feels pretty. This loss of its one attractive quality drives it into a deep sense of self-loathing and shame which is only cured by devouring supermodels, wealthy politicians, and anyone who's ever been on the Disney channel."

Not seeing how devouring any of those is really much of a problem.

Although not sure how you'd devour a supermodel, they're almost entirely bone and/or plastic.

Honestly, most of the pokémon fusions are from the Are-you-freaking-kidding-me and the I'm-so-gonna-die species.

That's B-Movie mad science for you. For some reason, creatures Arceus never intended always end up horrific, overly large, and with a taste for human flesh. Doesn't matter if its Rattata and Magikarp, it'll still end up nightmarish, with a taste for human blood, and looking suspiciously like a cheap costume or puppet made of rubber.
