Prompt: Casey Jones from TMNT gets hit with mutagen, turning him into goo spider.

   It was a typical Friday night for Casey Jones. Clad in his favorite hockey mask and holding onto a plethora of bludgeoning weapons, he had joined the teenage mutant ninja turtles in storming a foot clan hideout. Black hair flailing wildly as she clobbered one bad guy after another, he partially became blinded to his surroundings. Smashing his way through a collection of spider webs, his indiscriminate smashing led him to whack a baseball bat right into a vat of mutagen.

   When the vat burst open, there was little Casey could do to avoid his fate. Though he tried to jump away, he was nowhere near far enough to escape the downpour of grey goo. Covered in head to toe by the slimy substance, he tried to stand up and shake the stuff off, only to stop as his body was overcome by a series of wild tremors.

   As the mutagen seeped into his skin, his already built body swelled with added muscles. His skin became the same shade of grey as the mutagen, his flesh seeping out goo as he continued to change. With his tank top reaching its limits, it was the addition of four extra arms that spelled the end for his shirt. Flexing his new appendages and sprinkling the floor with his gooey mass, he barely paid any mind to the claws on his feet that helped his muscular legs leave the bottom part of his body mostly bare, save for a set of overburdened underwear.

   The fighting amongst the turtles and the foot clan came to a gradual stop as they noticed Casey. Seeing that everyone was looking at him, Casey pulled away at his mask to show of his collection of six, red eyes and the mandible sticking out of his mouth. Cracking his knuckles, the gooey man spider formerly known as Casey lunged forward to put his body to good use pummeling foot clan goons.
