The Coveted Transformation: Vaggie's Metamorphosis into Alastor's Mirror Image

Question: Write a transformation story of Vaggie (from the adults cartoon series Hazbin Hotel) turning into a completely identical clone of Alastor (also from the Hazbin Hotel series), complete with gender change (turning from female to male), age change, height progression, and, against her will, mind/mental change (with Vaggie's personality and memories being completely replaced with Alastor's personality and memories, making her, now him, completely forget he was a female fallen angel Vaggie and only remembered ever being Alastor the Radio Demon). For Vaggie's appearance, she is a slim fallen angel with muted gray-lavender colored skin. Her hair is white and has a jagged, moth-like shape to the cut, with gray-lavender stripes at the ends. She wears a large, ragged dark reddish-pink bow with two long tails on the back of her head, which reacts along with her moods. Vaggie's right eye has an ivory white iris and her sclera is light pink. Her left eye is missing and is replaced by a dark reddish-pink X on a slate-gray eyepatch, which glows when she is angry or irritated. She wears a dark pink blouse with a dark slate-gray peter-pan style collar, scalloped trim to the sleeves, and two buttons down the front. Her choker and skirt are the same dark slate-gray. Vaggie accessorizes with long slate-gray fingerless gloves and long thigh-high stockings, which are scalloped with white at the tops and the tips of the toes. Vaggie is a pragmatic and cautious angel who devotes a great deal of her time attempting to support Charlie with her vision for the hotel, as well as guiding her away from as much trouble or humiliation as possible. She is tough, but she has a heart of gold. Loyal and kind to those she cares for, but short on patience and trust, Vaggie tends to be very reactive, often taking an immediate defensive stance (with an offense at the ready) when it comes to dealing with potential threats towards either herself or Charlie. While it remains unclear whether Vaggie fully buys into Charlie's concept for redemption, she passionately defends it from more skeptical sinners and fully supports her idea, trying to do everything she can to help Charlie. Vaggie appears to be fairly prudent in business, trying her hardest to fill her designated role as the hotel's manager, even with an initial lack of resources, a very run-down property, and a lack of qualified staff. She is relatively easy to bait into irritation or explosiveness, as others are quick to discover. Angel Dust perceives Vaggie to have a distrust towards men in particular. Husk believes Vaggie acts mean to everyone else around her because deep down she loathes herself and that act is a way to protect herself. Back when she was an Exorcist, she was a ruthless killing machine, having slaughtered thousands of Sinners during many Exterminations. However, she had a change of heart when she encountered a defenseless Sinner child in an alley. Unable to bring herself to kill them, she let them go. Lute watched in disgust and declared her "sinful filth", gouging out her left eye and tearing off her wings as punishment, leaving her mutilated and abandoned. Shortly after, she met Charlie, who gave her first aid. The two eventually fell in love, and Vaggie became loyal and protective of her. This may have also helped Vaggie abandon most of her ruthless ways and change for the better. For Alastor's appearance (after Vaggie 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 is that Alastor is bored with himself around and he wanted more fun by cloning himself, and so (against Vaggie's will) he used supernatural powers to transform Vaggie, with Vaggie trying to resist the physical and mental changes, but to no avail (with Vaggie trying to use her fingers to push away a permanent smile and to frown, but to no avail and she is permanently smiling as Alastor's doppelganger, as the original Alastor said something like " Smile, my dear! You're never fully dressed without one"). There should also be quotes from the characters in this story (this story should include profanity/swear words (including but not limited to fuck, shit, bitch, etc) said by Vaggie herself, but Alastor does not use swear words with an exception of two uses of "fuck" and one use of "bitch") so we know what they're saying and what they're thinking.
