Prompt: (Mercy (Overwatch) Fat, Slug Woman TF) https://www.deviantart.com/platinumwaves/art/Mercy-w-Slug-Witch-skin-777928443

   On the night of Overwatch’s costume party, Mercy was overjoyed to finally get a chance to show off her costume. The witch’s outfit came with a cute, black pointed hat and a pair of skeleton wings that she had managed to get working with a bit of tweaking. Tucking her blonde hair beneath the rim of her hat and picking up her witch’s staff, she walked towards the finishing touch of her costume.

   Packaged in with the outfit was a spell book. The dusty old tome claimed to be a genuine article that held a bevy of magical incantations. Being a woman of science, Mercy saw the hundreds of pages of intricate phrases as nothing more than someone putting in the extra effort to make it look as authentic as possible. On a whim, she turned over to a random page and began to spout off the magic words for a spell labeled “Slug Syndrome.”

   As the words left Mercy’s mouth, she fell into a sort of trance. She continued to speak the words, even as a layer of green slime began to appear across her skin. The gelatinous goo shuddered as her once slim body began to fatten up into a mess of blubbery flesh. Her outfit began to tear apart to make way for her growing form and the thick tail that had taken the place of her legs. Managing to finish off the spell even as her face became covered in dark green splotches and her face was packed on with pudgy cheeks and multiple chins, Mercy finally broke out of the trance upon speaking the last word.

   Blinking a few times to get a handle on her surroundings, she wriggled her way over to her dressing mirror. Her gaze drifted across her sluggish body, stopping to take in every added pound and heap of slime that had encased her form. Rather than fear or disgust, Mercy put on a smug smile as she began to slither out of her room. Reversing her condition could come later, for the moment what was important to her was claiming first prize in the costume contest.
