Vaggie's Twilight Transformation into WereAlastor

Prompt: Write the transformation story of Vaggie (from an adults cartoon/animated series Hazbin Hotel) being cursed and transformed at every full moon night into an identical twin brother of Alastor (also from the adults cartoon/animated series Hazbin Hotel), complete with clothes change (Vaggie's clothes turning into an identical outfit to Alastor's outfit), gender change (her breasts flattens to nonexistence as her body feels more masculine and losing the feminine curves to fit her new self as a WereAlastor/Were-Alastor, and her female genitals (vagina, ovaries, and uterus) inverts itself before pushing out into testicles and a penis), age change (becoming the age of 30s-40s years old, exactly as left off from Alastor's death from his human life in 1933), height progression (growing from 5.6 feet tall to 7 feet tall), voice change, and mind/mental change (with Vaggie's personalities and memories being permanently and completely replaced with Alastor's personality and memories, despite her (now his) best efforts of fighting the new personality and memories, making him completely forget about his past self and only remember being Alastor the Radio Demon). For Vaggie's appearance, she is a 5.6 foot tall slim-figured fallen angel who subtly sports a moth-themed design with grayish-lavender skin. She has knee-length grayish-white hair with faded-purple tips and long jagged bangs which cover the left side of her face. On the back of her head, she accessorizes with a red hairbow with small tears on each side and two long tails. Her right eye has a light pink sclera and an ivory iris, while her left eye has been replaced by a slate-gray eyepatch that sports a red-pink "X" shape, which glows when she is angry or irritated. Her mouth has small fangs and black lips. Vaggie wears a blouse that is the same color as her bow and the "X" shape on her eyepatch, with a dark gray peter-pan collar, dark gray trimming on the sleeves, and two dark gray buttons down the front. She also sports a choker and a miniskirt with a thick pale pink waistband hugging her waist, both colored in the same dark gray. Vaggie's accessories include a set of fingerless slate-gray opera gloves with matching thigh-high stockings, which include white scallops at the cuff and toes. Here are Vaggie's powers and skillsets; Flight (When she was an Exorcist angel (before the events of the Hazbin Hotel series), she had wings until she was stripped of them by Lute, along with her status, but she later regains them in the episode "Hello Rosie!" after training with Carmilla Carmine), Hand-to-hand combat (Vaggie demonstrates a considerable physical strength that belies her slight frame. She was able to swiftly punch a male demon off his chair in one bare-knuckle hit, as well as pick up and toss both Sir Pentious and Angel Dust off a rooftop), Weapon proficiency (Vaggie is proficient in handling weapons, seeming to favor blades. According to Adam, Vaggie was one of his top Exorcist fighters, claiming that her skills in weaponry allowed her to kill thousands of Sinners. Although she has yet to actually make use of her larger weapons, she does not lack confidence when it comes to brandishing them for self-defense, and she was able to throw a dagger into the electric window switch of a car with pin-point precision. As noted by Carmilla, Vaggie's fighting style initially resembled that of the other Exorcists, sloppy, vicious, and straightforward, focusing everything on offense. She eventually began to overcome these flaws as she sparred with her), Bilingualism (Vaggie can fluently speak Spanish as well as English), and Intellect (Vaggie appears to have quite a comprehensive knowledge regarding the hierarchies and folklore of hell, particularly those pertaining to her area of residence, the Pride Ring, and the machinations of the power-jostling sinners located there. She understands the looming dangers of the Overlords and their politics, as well as the tale of how Alastor became the first mortal soul to harness enough power to "begin to topple overlords who had been dominant for centuries"). She also has Throwing daggers (although whether Vaggie has the power to summon them or just keeps them on her is unclear) and an Angelic spear (Vaggie possesses a spear for self-defense and is seen carrying it around with her. She had this spear since her days as an Exorcist). Here is Vaggie's personality; she is a pragmatic and cautious angel who devotes a great deal of her time attempting to support Charlie with her vision for the hotel " Hazbin 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. Despite abandoning her Exorcist past and beliefs, she kept her spear for protection and is still wary of Sinners who could potentially be a threat to her and Charlie. For Vaggie's preferences, she likes/loves Charlie Morningstar (her girlfriend), supporting Charlie's dream, spending time with Charlie, protecting Charlie, and Adam's death; however, she dislikes herself, Charlie being insulted or harmed, Charlie getting ahead of herself all the time, anything messy, Angel Dust's attitude, Alastor's attitude, Heaven, the extermination, Adam and Lute tormenting her, Emily (a seraphim angel) getting close to Charlie, failing Charlie and her dreams, Charlie knowing about her past as an Exorcist, and seeing Charlie saddened. For Alastor's appearance, 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 has no ability to frown due to this permanent smile). He is approximately 7 feet tall. He is completely hairless except for his eyebrows, eyelashes, and the hair on the side, back, and top of his head (like a human's). 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. His voice also sounds like it is coming from an old-fashioned vintage radio. Alastor has many supernatural powers, such as demon transformation (the ability to turn into a more powerful demon form), 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). 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 Vaggie, while wandering through the Hazbin Hotel (located near Pentagram City, which is located in the Pride Ring of Hell), encounters Alastor the Radio Demon himself, much to Vaggie's annoyance, with Vaggie not knowing what Alastor is doing and she asks Alastor on that, before Alastor says that nothing much before confirming that he wants more entertainment on full moon nights. Veggie is confused by what Alastor said, but she is then bitten by Alastor in the throat and ripping chunks of flesh, causing major blood loss (Vaggie however survives, she is just injured before the wound almost instantly heals itself to being just a scar), before Alastor tells Vaggie not to worry and it's only the beginning. Vaggie, (while Alastor stands nearby and eager to watch Veggie transform under the full moon), after she is bitten by Alastor, then sees that a full moon is out, and she undergoes a transformation (against his/her will) into an identical clone of Alastor the Radio Demon, in not just the body (with her shocked and disgusted by her gender changing, making her realize that she is now a man, even commenting on that), but also the mind (Vaggie tries to fight back all the physical and mental changes and she tries to call for help from Charlie Morningstar, but to no avail), leaving Vaggie now completely transformed into Alastor (known to himself and the other demons as "Were-Alastor" or "WereAlastor" (which Alastor also likes to call the transformed Vaggie every full moon night after transforming from Vaggie herself, even claiming to other demons that he is "Were-Alastor" or "WereAlastor") due to transforming from a fallen angel demon every full moon night). The original Alastor, who had placed a curse on Vaggie just by biting Vaggie, watches the transforming Vaggie and instantly befriends the new Alastor. The new Alastor, formerly Vaggie, now broadcasts throughout Hell alongside the original Alastor, with both the original Alastor and the new Alastor also killing and feasting on any weak sinner demons and make deals with some other demons every night when the moon is full (Vaggie transforms back to herself as Vaggie when daytime arrives, but always transforms into Were-Alastor/WereAlastor). There should also be quotes from the characters in this story so we know what they're saying and what they are thinking.
