"The Enchanted Metamorphosis: Sir Pentious's Unwilling Transition into Alastor's Mirror Image"

Question: Write a transformation story of Sir Pentious (from the adults cartoon series Hazbin Hotel) turning into a completely identical clone of Alastor (also from the Hazbin Hotel series), complete with age change, height progression, and, against his will, mind/mental change (with Pentious's personality and memories being completely replaced with Alastor's personality and memories, making him completely forget he was a legless snake-like demon Sir Pentious and only remembered ever being Alastor the Radio Demon). For Sir Pentious's appearance, he has a snake-like appearance with a body color predominantly in charcoal grey. His eyes has cerise sclera with black pupils, and a mouth with sharp yellow teeth, two of which are long snake-like fangs. His tail is black with thick yellow stripes featuring numerous cerise eyes running down the length of it. He has a black cobra hood with its front colored yellow with black corners and four cerise eye patterns spread across the center. Sir Pentious wears a jacket in a matching charcoal grey to his skin, pinstriped with yellow, and a black bow tie with a single cerise eye in the center. Beneath the jacket is a long-sleeved yellow undershirt. He also wears black fingerless gloves with yellow dots on each knuckle and have sharp cerise claws. He accessorizes with a large top hat in charcoal grey, which has a sizeable cerise eye in the center of it, as well as many sharp yellow teeth and a pair of goggles. The top hat blinks and changes expressions in unison with Sir Pentious. Sir Pentious is bombastic, flamboyant, short-tempered, temperamental and persistent, and his personality seems to take cues from the classic "mustache-twirling" stock villains. He takes tremendous pride in his grandiose ideas of how evil and cunning he is, and at one point even openly declares "I'm so evil!" He uses his mechanical genius to build weapons, such as a cannon and his airship. However, he is more than capable of showing remorse and has a sense of honor. He demonstrates this when he accepts his defeat and "inevitable death" at the hands of the Hotel staff after being reprimanded by Vox for failing. When Charlie forgives him, he is grateful and fully joins in his redemptive effort. Additionally, he is enthusiastic about Charlie and Vaggie's activities, more so than Angel Dust, even if it were an act. According to Husk, Sir Pentious is a lonely jester who likes to watch others while they sleep. He strives to be hip and cool. As Angel Dust noted, Sir Pentious is oblivious to sexual innuendos and tends to take things he is told very literally. He is emotionally attached to Egg Boiz and breaks down crying because Vaggie forced him to get rid of them. Humorously, the moment he retrieves them, he briefly expresses his relief and then orders them to make his bed. When it comes to Egg Boiz from him, he is used to the fact that they have always said "random nonsense" all the time, causing a huge downfall for him and his friends when one of them, Frank, actually said something. which was true; that an angel (more specifically, an exorcist) was killed. For Alastor's appearance (after Sir Pentious 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-ensnared-songbird-a-tale-of-shifting-identities-in-the-symphony-of-hell/ . After turning Husk into Alastor's new doppelganger, he wanted more fun and more clones of himself, and so (against Pentious's will) he used supernatural powers to transform Sir Pentious, with Pentious trying to resist the physical and mental changes, but to no avail (with Sir Pentious trying to use his fingers to push away a permanent smile and to frown, but to no avail and he is permanently smiling as Alastor's doppelganger, as both the original Alastor and his other doppelgangers, formerly Vaggie and Husk, 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.
