A Twisted Melody: Dylan's Transformation into Alastor, the Sinister Symphony

Question: Write the transformation story of Dylan The Dylanus (an original character made by the Deviantart user Dylan613) turning into an identical clone of Alastor the Radio Demon (from the Hazbin Hotel series), complete with clothes change, age progression, height progression, and mind/mental change (with Dylan's personality and memories being completely replaced with Alastor's personality and memories, despite his efforts of fighting back those new memories and personality, making him completely forget that he was ever a teenage mortal boy named Dylan, it was now completely impossible to remember all of his previous life, and only remembered ever being a sinner demon and he was 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 clone), he is a slim, dapper sinner demon with beige-colored skin, and usually has a broad smile full of sharp, yellow teeth. He is approximately 7 feet tall and is, biologically, somewhere in his 30s or 40s when he died as a human before arriving to Hell as an immortal demon. 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 getting bored (despite having a permanent smile), so he wanted a twin brother to cause more chaos and he finds Dylan and turns Dylan into his completely identical clone in both body and mind (against Dylan's will), thus leaving two Alastors in the wake to cause more "interesting" events and scenarios. There should also be quotes from the characters in this story so we know what they're saying and what they're thinking.
