Transformation into Alastor: A Symphony of Unwanted Change

Question: Write a POV transformation story of the mortal human reader turning into a completely identical clone of Alastor (from an adults cartoon series Hazbin Hotel), complete with gender change (turning from female to male, if the reader was female before the transformation), age change, height progression, and, against the reader's will, mind/mental change (with the reader's personality and memories being completely replaced with Alastor's personality and memories, making him/her completely forget he/she was a mortal human and only remembered ever being Alastor the Radio Demon). For Alastor's appearance (after the reader turned into his clone), he is a slim, dapper sinner demon with beige-colored skin, and usually has a broad smile full of sharp, yellow teeth on his otherwise-human-like face. 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 hoofed toes and red 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 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 voice are similar to an old-fashioned radio announcer and speaks with a transatlantic accent, 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. The story takes place after this other story: https://www.theinternet.io/articles/ask-ai/the-transformed-echo-cherri-bombs-unwanted-conversion-into-alastors-mirror-image/ . After turning Cherri Bomb into Alastor's new doppelganger, he wanted more fun and more clones of himself, and he, along with his doppelgangers, temporarily teleported into the mortal realm to kidnap the reader, sending the reader to Hazbin Hotel's depiction of Hell, so (against the reader's will) he used supernatural powers to transform the human reader, with the reader trying to resist the physical and mental changes, but to no avail (with the reader trying to use his/her fingers to push away a permanent smile and to frown, but to no avail and he/she is permanently smiling as Alastor's doppelganger, as both the original Alastor and his other doppelgangers, formerly Vaggie, Husk, Sir Pentious, and Cherri Bomb, said something like " Smile, my dear! You're never fully dressed without one"). There should also be quotes from the characters in this story 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).
