A Twisted Symphony: The Perverse Transformation of a Mortal into Alastor, the Chaotic Radio Demon

Question: Write a POV transformation story of a mortal human reader turning into an identical clone of Alastor (from the adults animated series Hazbin Hotel), complete with gender change (if the reader is a female), clothes change, age change (becoming the age of 30s-40s years old, the same age as Alastor's exact age as Alastor, exactly as left off from Alastor's death from his human life in 1933, becoming immortal in the process), height progression, voice change (the reader's voice becoming the exact same voice as Alastor's voice), and mind/mental change (with the reader's personalities and memories being permanently and completely replaced with Alastor's personality and memories, despite the reader's best efforts of fighting the new personality and memories, making him/her completely forget about his/her past self and only remember being Alastor the Radio Demon). For Alastor's appearance (after the reader turned into his clone), he is a slim (having an unnaturally thin torso, neck, arms, and legs, except his shoulders are broad), dapper sinner demon with beige-colored skin, and usually has an unnaturally broad smile (reaching from each cheek's upper area) full of sharp, yellow teeth. He is approximately 7 feet tall. He sports a pinkish-red cropped, angled bob-cut with black tips at the ends and two large, black tipped tufts of hair extending from the top of his head, evoking the ears of a deer. The style has an undercut at the back, and two small black antlers protruding from the crown, which can grow in size in his full demonic form. Alastor's eyes have dark-red sclerae, bright-red irises and thin black pupils (which can change into the shape of radio dials when shifting into his full demon form). His forearms and lower legs fade to dark grey, and he has red hoof-toed feet and red clawed fingers. Alastor wears a red pinstripe coat with dark-red lapels piped with white, which is ragged along the bottom hem. Underneath this he wears a bright red dress-shirt with a black cross on the chest, and long black dress pants with matching bright red cuffs. He also wears a dark-red oval-shaped monocle, rimmed with black, over his right eye. He accessorizes with a black knotted bowtie with a bright red center, black gloves with red at the fingertips, and black pointed-toe boots with red deer hoofprints emblazoned on the soles. Alastor also carries a thin cane with a sentient vintage style microphone attached to it, which he uses to play sound effects and broadcast his voice. Alastor has many supernatural powers, such as demon transformation (the ability to turn into a more powerful demon form and control this shapeshifting ability, and return back to his default self on command), tentacle creation (the ability to produce black tentacles from his back and can create tentacles from outside his body, such as summoning tentacles through a portal), flexibility (able to contort his body into numerous unnatural poses), demonic magic (able to cast magic thanks to the high power-level he has accrued in the demon ranking system, this magic takes the visual form of glowing red symbols that resemble Voodoo veve, which float around him), shadow manipulation (able to summon shadows and manipulate them into doing his bidding), spatial warping (able to get around with the help of his shadow, allowing teleportation through this ability), portal creation (able to transport others to his location easily via the portals he makes), pyrokinesis (able to summon small balls of fire for display purpose), phytokinesis (able to make plants wilt with a single stare), manifestation, photokinesis (able to project red glowing light from his eyes as well as his microphone), and outfit alteration (capable of changing the outfits of his targets as well as his own with a snap of a finger). He is also capable of various other abilities including deal-making (as Alastor is known to be a deal-maker demon; deal-maker demons like Alastor can increase their power by dealing in souls, which is a very powerful commodity in hell, so they’re seen as very manipulative and not to be toyed with, deal-making is not something every demon can do, as such it is not to be taken lightly as it doesn’t generally work out well for the other party), broadcasting (when he was a living human, Alastor's profession was as a radio show host, and he continues his broadcasts in Hell as a demon, ensuring that Hell's denizens are aware of his activities over the airwaves, earning him the title of "The Radio Demon"), bilingualism (Alastor can speak English fluently as well as some broken Creole French), cooking (Alastor is noted to be "a big foodie" and mentions having admired his mother's cooking, specifically her Jambalaya), musical/dancing/theatrical talent (Alastor is known to display moderate vocal abilities and excels at dancing, with some people noting tap to be a style he excels in specifically, he also shows a flair for theatrical showmanship), and wide intellect (Alastor is known to be quite a cunning individual, resulting in him accruing a large amount of power through his tricks and deal-making). When in his full demon form, Alastor's body grow more elongated (making him even taller, more than 10 feet tall) and with broader shoulders (although his clothes grow with him to fit this form and his limbs become longer, his neck gains extra joints, and his black antlers grow in size to become massive black antlers. In Alastor's full demon form, his sclera turn black with his pupils turn into the shape of radio dials. His suit and ends of his mouth, in his full demon form, also gain stitches along them. For his personality, Alastor stands out from many of the more chaotic residents of hell for his well maintained amiable persona. He gives the first-impression of a good-natured and charming man, wearing a permanently wide grin on his face at all times. Alastor's behavior, mannerisms, and even his manly voice are similar to an old-fashioned radio announcer and speaks with a transatlantic accent (always literally sound like he is talking through a vintage radio), often using quaint anachronisms such as "the picture show" and refers to Charlie as a "charming demon belle". This playful dandyish exterior, however, obscures a much darker side to him - one with high levels of self-importance - and he will not hesitate to use physical violence when others don't act in line with his very particular values or expectations. For Alastor's preferences, he likes/loves smiling, invading people's personal space, his mother and her cooking, the "picture show", strong liquor, cooking, people failing, playing pranks, black coffee, bitter tastes, theater, dancing, the Stock Market Crash of 1929, and venison; however, he dislikes being touched, dogs (possibly related to his death as a mortal human in 1933), frowning, tea, anything sweet, Angel Dust's sexual remarks, post-30s' technology, and anyone ruining his outfit. The story is that Alastor is getting sick and tired of being viewed as an evil monster, and to his dismay, the human reader views demons (who he/she is afraid of) as nothing more than stereotypical pure evil monsters. So Alastor (by some supernatural means and to teach the reader a lesson (plus he wanted a twin brother)) briefly left the series' Hell and into real life to kidnap the reader and sent him/her to the world of Hazbin Hotel before using his supernatural magic at the reader which turned the reader into his completely identical clone in both the body and the mind. The transformed reader is unable to stop smiling (he/she has a permanent smile against his/her will), with the reader trying to frown or push his/her mouth to the opposite emotions aside from smiling with his/her own fingers, but to no avail. During the physical transformation (before the reader's memories and personality are replaced with Alastor's memories and personality), the reader is horrified, hoping that everything that was happening was just a bad dream and hoping to wake up (possibly by either closing eyes or by pinching himself/herself), but sadly, this is all happening for real. Despite the reader's efforts, the reader is unable to fend off the new personality and memories, thus permanently turning the reader into Alastor's identical twin brother. The transformation is permanent (meaning it is forever) and is completely irreversible. There should also be quotes from the characters in this story so we know what they're saying and what they are 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).
