"The Curse of the Were-Alastor: The Transformation of Dylan into the Radio Demon"

Question: Write the transformation story of Dylan The Dylanus (an original character made by the Deviantart user Dylan613) being cursed and transformed at every full moon night into an identical twin brother of Alastor (from the adults cartoon/animated series Hazbin Hotel), complete with clothes change, age progression (becoming the age of 30s-40s years old, exactly as left off from Alastor's death from his human life in 1933, becoming immortal in the process), height progression (growing from 4.9 feet tall to 7 feet tall), voice change, and mind/mental change (with Dylan's personalities and memories being permanently and completely replaced with Alastor's personality and memories, despite 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 Dylan's appearance, he is a 4.9 foot tall, 15 year old boy who has a lean build for his size, tan skin, medium-length brown hair (that reaches his chin, although not covering his face at all), and has green irises. He wears a dark blue hoodie, a lighter blue t-shirt underneath, and cyan wear jeans. He also has white socks underneath his black tennis shoes, which have an x-shaped gray marking on each of his shoes' tongue. Dylan is a kind, considerate, smart, and understanding character, who is a love interest to Emma (his girlfriend) and is playful around his slightly older, smarter brother Black. Despite his small frame and being a teen, he goes in the way to protect his homeland against various villains and monsters (always successful, even if some are more difficult than others). Despite these traits, he does have some flaws, such as his intolerance to swearing (which aren't present in his homeland), being quite weak without superpowers (which he actually does not have and only obtains them when using special devices), and has fear of vampires and demons alike since he views them as nothing more than pure evil monsters. For Alastor's appearance (after Dylan turned into his identical twin brother every full moon night), 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 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 Dylan has been cursed by being attacked by Alastor the Radio Demon himself, with Alastor biting Dylan in the throat and ripping chunks of flesh, causing major blood loss (Dylan however survives, just injured), before Alastor tells Dylan it it's only the beginning of the curse. Just days later, at one night, when the moon is full (and after Dylan sees the full moon), Dylan undergoes a transformation. But he does not transform into a werewolf as he initially believes/thinks by the start of the transformation, instead, Dylan transforms (against his/her will) completely into an identical clone of Alastor the Radio Demon, in both body and mind, every full moon night (Dylan tries to fight back all the changes and call for help from his brother Black and his girlfriend Emma, but to no avail), leaving Dylan now completely transformed into Alastor (known to himself and the terrified humans as "Were-Alastor" or "WereAlastor" (which Alastor also likes to call himself every full moon night after transforming from a mortal boy, even claiming to scared mortal humans that he is "Were-Alastor" or "WereAlastor") due to transforming from a mortal boy every full moon night). The original Alastor, who had placed a curse on Dylan just by biting Dylan a few nights earlier, watches the transforming Dylan and instantly befriends the new Alastor. The new Alastor, formerly Dylan, now broadcasts throughout the mortal realm (Earth) alongside the original Alastor, with both the original Alastor and the new Alastor (known as "Were-Alastors" or "WereAlastors") also killing and feasting on any mortal humans and their souls from the mortal world every night on Earth when the moon is full. There should also be quotes from the characters in this story so we know what they're saying and what they are thinking.
