A Twisted Transformation: From Human to Fizzarolli's Mirror Image

Question: Write a POV transformation story of the male human reader turning into a completely identical clone of Fizzarolli (from the Helluva Boss series), complete with clothes change, age change, height change, semi-robotification (arms and legs becoming robotic), and mind/mental change (with the reader's personality and memories being completely replaced with Fizzarolli's personality and memories, despite his fears of becoming a demon and his efforts of fighting back those new memories and personality, making him completely forget that he was ever a mortal human, it was now completely impossible to remember his past mortal self, and only remembered that he was always Fizzarolli the jester imp). The transformation into Fizzarolli is permanent (meaning it's forever) and completely irreversible. For Fizzarolli's appearance (after the human reader turned into his clone), he is a tall, slender 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 nose. 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 devil-like imp tail with black stripes, however the stripe in the middle is white. His cybernetic arms and legs are retractable, able to extend and bend far more than normal jointed limbs could and 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 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 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 fifteen years prior to the episode "Oops", 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, 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. The story is that Fizzarolli wanted an identical brother of his own to make his circus show much more interesting and popular, so he finds the male human reader and kidnaps him (leaving the reader horrified) before strapping the reader onto a transformative machine that some staff members of Fizzarolli's circus invented, before he activates the machine that turns the reader into his completely identical twin brother in both body and mind (against the reader's will), thus leaving two Fizzarollis in the wake to make the circus more famous. There should also be quotes from the characters in this story so we know what they're saying and what they're thinking.
