You got yourself a Fennekin and named her Delphina, she was such a cutie patootie, always hyper, playing around a lot, she even won your parents over, and they don't really like pokemon, but there's a thing Delphina absolutely love, good food, more specifically human food, at first it started small, givibg her a piece of ham, a piece of cheese, berries, there was nothing she wouldn't eat! Then she evolved into a Braixen, and you noticed, she got quite the chub on her, big belly, big thighs and a squishy behind, despite that, her weight hasn't stopped her at all, yeah she's slower in combat, but goddamn she can take a hit, you swear even physical attacks kinda bounce off of her, and of course, with her evolution she became hungrier, now she could eat three times what a full-grown human could, but despite that, her attacks and defense got better, which honestly to you, it was pretty useful, and hey, she got really great and cuddling, you could just bury your face in her tummy and use it as a pillow, now, a few months back finally she evolved into a Delphox, she's now pretty damn tall, and even thiccer than before, and a lot more hungrier, this Delphox could out-eat a Snorlax and basically tank a water-ice type with no issues! She may have also developed an interest in witchcraft, but the good type, making things useful for you and others, which is nice, not having to spend your money to buy healing potions and stuff to heal burnings, paralyzis and poison damage, and even despite her increased weight, she doesn't have any weight-related issues, strangely enough, and she doesn't look fat, more like curvy with a big belly, though you try to control her portions so she doesn't become inmobile, she obviously doesn't like that so she sometimes sneaks food behind your back, today is one of these days, you come back to your hotel room after running some errands, and of course, you catch Delphina eating a bunch of cheeseburgers and fries, she just, smirks at you and slowly eats a fry, as if to silently challenge you to stop her from eating.
