Reader's Metamorphosis into the Hellborn Jester

Prompt: Write the POV transformation story of the human reader completely turning into Fizzarolli (from the adult cartoon/animated series Helluva Boss), complete with gender change (if the reader is a female, the breasts flatten and vanish while her vagina, ovaries, and uterus invert itself and push out into a penis and testicles, however this is optional and is only if the reader is a female), clothes change, age change, height change (turning from average human size of 5.6-6 feet tall to 5.3 feet tall), voice change, semi-robotification (due to the readers's arms and legs becoming noodle-like robotic limbs, while his torso and head remain flesh and blood unlike the fully-robotic limbs), and mind/mental change (with the reader's personalities and memories being completely replaced with Fizzarolli's personality and memories, despite his/her best efforts of fighting the new personality and memories (making him/her scared of forgetting or losing his/her self), making the reader permanently and completely forget about his/her past human self (truly believing his former human life was just a fantasy/dream and was never real to begin with, unable to know/remember that the transformation had happened a moment ago) and only remember that he was and has always been a hellborn demon (more specifically an imp) named Fizzarolli, and that he has always been a clown/jester of Hell). The transformation into Fizzarolli is permanent (meaning it is forever) and completely irreversible. For Fizzarolli's appearance (after the reader turned into him), he is a tall, slender/lanky male imp with a jester getup. Like all imps, he has a short reptilian-looking muzzle with sharp teeth in it, and he lacks any visible ears or nostrils. He lacks any hair on his head and his body. His eyes have lime sclera and pink irises, his sharp teeth are neon blue, and he has a long devil-like prehensile imp tail with black stripes, however the stripe in the middle is white. His thin, cybernetic arms and legs are retractable, able to extend and bend far more than normal jointed limbs could (despite being noodle-like in shapes, they are powerful and can carry anything as heavy as a very large car), and his cybernetic arms have a light blue circle on each shoulder and light blue spots on his knuckles. The majority of Fizzarolli's head is covered in a huge burn scar, with the only parts unaffected being the tip of his mouth and a small part of the back of his head, which show his original red skin. His face also has black dots at the ends of his mouth, and he has a forked tongue that has a couple of black stripes on it as well. He used to have exceptionally large horns for an imp, but were damaged and cauterized by the fire. He wears a bright red and blue jester cap with bells, a white ruff, and a black collar with bells located below it. His jester hat's stripe patterns resemble those of his horns' as a child, being asymmetrical from both sides. The front side of his outfit is bright red with yellow trim at the bottom with yellow hearts, while the back is bright blue with white trim at the bottom and black hearts. He wears white and purple striped pants along with white and purple striped sleeves with bright red cuffs and yellow trim edging, and yellow balls on his shoulders with light red hearts. He also wears black, heeled shoes with yellow hearts on the front, black gloves with red spots on the knuckles, and yellow cuffs. For Fizzarolli's abilities, he has charisma, high intelligence, flexibility, musical talent, cybernetic/artificial limbs, sign language, juggling, roller skating, distraction tactics, and can drive cars very well. For Fizzarolli's personality, he is a theatrical demon, with a fast-talking demeanor and a crude sense of humor. Extremely vulgar in nature, he constantly makes sexual jokes and puns, to the degree he pairs up with Asmodeus in openly condescending sentimental relationships (since Fizzarolli is a boyfriend to Asmodeus) and offering lewd suggestions. He was shown to be especially condescending towards Blitzo, with whom he has a bad history with, which stems from an accident that happened at Cash Buckzo's circus (when Fizzarolli was a young adult) fifteen years prior to the episode "Oops" (leading to Blitzo to run away and not join any circus ever again), however Fizzarolli found it in him to forgive Blitzo after the latter rescued him from Crimson and Striker. Early in the series, Fizzarolli seemed to embody Blitzo's comments about being an overrated sellout clown, given how he did not seem to mind having his image exploited by Mammon's corporate marketing because it made him popular and famous for being a Sins name-brand figure. This included having no issue with his likeness being marketed for a line of sex toys, despite how it secretly creeped him out. He also dislikes the creepy fans who enjoy the Robo Fizz sex toys, even secretly ordering the staff at Ozzie's to keep a creepy fan far away from him after they proclaimed they owned four. Despite his normal jovial nature Fizzarolli suffers from extreme self-worth and self-image issues, the latter of which mostly originating from the severe injuries he received from a circus fire that he was involved in when he was younger. Because of this, he feels like he needs to do whatever Mammon tells him to do, as he feels he must repay the man for all the fame and success being his brand figure has brought, despite how horribly he is treated. He also believes unless he keeps propitiating the fame and admiration he will be nothing and will lose Asmodeus (a boyfriend to Fizzarolli), as he's only ever seen him as he claims it "his best", and believes he is barely worthy of working with a king of sin because of his disfigurement. For Fizzarolli's preferences, he likes ridiculing Blitzo (formerly), fame, working for Mammon, eating burgers, juggling, playing with airhorns, and spending time with Asmodeus (who he has a gay/homosexual relationship with), but he dislikes pirates (when he was a child), blood, sharp objects, obsessive fans, Mammon's abuse to Fizzarolli, Striker's breath, being exploited, disappointing Mammon, performing under pressure, and going outside alone. He is often nicknamed "Fizzi", "Fizz" (named by Blitzo), "Fizzie" (named by Asmodeus and Mammon), "Fizzie Frog" (named by Asmodeus), "Froggie" (named by Asmodeus), "Peppy Little Fuckdoll" (named by Blitzo), "Jester" (named by Blitzo), "Babe/Baby" (named by Asmodeus), "Clown" (named by Crimson and Striker), "Royal Jester" (named by Blitzo), "Mr. Ten years running" (named by the clown pageant announcer), "Little joker" (named by Asmodeus), "Fizza-rotty" (named by Glitz and Glam), "Bright Shiny Brand-baby" (named by Mammon), and "Stupid Little Cunt" (named by Mammon). The story starts when the reader, a human guest/patient/subject (not a scientist), is in the laboratory somewhere, where the scientist(s), who's human like the reader, had invented a transformation chamber (which resembles a massive pod with a circular window on it for the scientists to see the reader, and a mirror inside for the reader to see himself/herself) and tells the reader to go into the contraption, before the scientist(s) had started the machine and activates the reader's transformation. The scientist(s)'s plan is the bring their favorite TV show to life and that is by completely transforming a human subject into one of the characters of the show. During the reader's mental changes, the scientist(s) would tell the reader to wait for their new identity to finalize (the reader's brain at that point would be completely fuzzy or foggy due to the mental change until the reader's mind cleared up with complete certainty that he was always an imp and his name being Fizzarolli, he would have no memory of ever being human to begin with, and instead he knows that he was always Fizzarolli, who is an imp and the famous jester/clown of Hell). The scientist(s) would also confirm to each other that the other Helluva Boss characters will eventually be made real too (other human subjects would be used too), including Asmodeus (who Fizzarolli wants to be with again, since he truly loves Asmodeus, his boyfriend, and he is truly happy about Asmodeus coming back to him again, he is completely unaware that Asmodeus was not real in reality but the scientists are secretly, without Fizzarolli knowing, working on making Asmodeus and all other demons from the Helluva Boss series all real (by inviting other human guests/patients/subjects into the machines, similar to the one the reader was in before he/she became Fizzarolli, thus turning other human guests/patients/subjects into Helluva Boss's demon characters with the same type of machine) just like Fizzarolli himself (without telling Fizzarolli since Fizzarolli believes that all demons, including himself, from his world do actually exist), bring them to real life on Earth, and the scientists tell Fizzarolli that Asmodeus will be with Fizzarolli again, now on Earth rather than in Hell). There should also be quotes from the characters in this story (with some like Fizzarolli even using swear words such as, but not limited to, f-bomb words, despite the human reader (before his mental change) never using strong language unlike his new Fizzarolli self, so the reader would not use swears words until the mental change occurs) so we know what they're saying and what they're thinking. Also, it is a POV reader story, so it should not be in an author's point of view (my, I, mine, etc), and it should be from the point of view of the reader (you, your, etc).
