Alastor's Transformation into May: Journey to Become an Ultimate Pokémon Trainer

Prompt: Write a transformation story of Alastor (from an adult cartoon/animated series Hazbin Hotel) turning into May (in her outfit from Pokemon Ruby and Sapphire anime series) from the Pokemon anime, complete with gender change (turning from male into female), clothes change, height regression, age regression, reality change (Alastor's world becoming the world of the Pokemon anime), and mind/mental change (with Alastor's personality and memories being completely replaced with May's personality and memories, despite his, now her best efforts, making her completely forget that she was ever a demon or a male named Alastor, only remembering that she was a little human girl, as well as being a Pokemon trainer, and her name was May). For Alastor's appearance, 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. 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 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). Alastor stands out from many of the more chaotic residents of hell for his well maintained amiable persona. He gives a first-impression of a good-natured and charming man, wearing a permanently wide grin on his face at all times. His 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. He is noted to be narcissistic, with his love for himself being stated that no one else can measure up to it, and he does not see many people quite up to his level. Alastor is described as a man of duality. He values good manners, affability and intelligence very highly in others, and will actively look down on those who do not meet his standards, however he will often play fast and loose with these arbitrary rules in regards to himself and his own conduct. Alastor has an odd sense of morality, which is described as "not normal", and has been noted to be quite sadistic, even cannibalistic, devouring lesser demons or those that have incurred his anger. Despite this, he keeps close friends with the other cannibals of Hell, including the denizens at the Cannibal Town. His smiling is a very self enforced form of ego and a show of power and dominance; he looks down on anyone who lets their true emotions show, and even when faced with a rival in strength, if they let slip a frown, Alastor will see them as truly weak. His smile is also to be more unpredictable and unnerving, and gives him a feeling of complete control over himself. While Alastor is powerful, he is aware that there are other demons and entities that rival him in terms of power, such as other Overlords. For this reason, he is wary around such demons, as they could potentially harm him if he is not careful. Despite everything, Alastor does genuinely seem to want to help Charlie run the Hazbin Hotel, albeit for his own amusement, and hopes for its failure over siding with her idealism. Alastor also dismisses the idea that redemption is possible as laughable, nevertheless, he fulfills his role as patron as promised, providing the hotel with staff, and protecting Charlie and her business from outside threats. He views the whole endeavor as a fun distraction from his decades of boredom. Despite consistently having a confident and cheerful demeanor, he harbors a vulnerable side that becomes apparent when confronted with reminders of being "chained". In this instance, his facade of certainty crumbles, and he succumbs to panic attack. According to Mimzy (Alastor's friend), when Alastor was alive he would become a "kitten" (not literally a kitten) if he drank enough rye whiskey while jazz music was on. Here are Alastor's preferences (his likes and dislikes); he likes himself (including his own fashion style), smiling, doodling, gossip and drama, invading others' personal space, his mother and her cooking, jazz music, strong liquor, cooking, seeing people fail, playing pranks, bitter tastes (especially those of black coffee), theater, dancing, the Stock Market Crash of 1929, venison, being in charge, Charlie's potential, pineapple on pizza, and making jokes. However, he dislikes Lucifer Morningstar (the king of Hell and Charlie Morningstar's father) and his "tacky" circus décor, Susan (a Cannibal Town resident), being touched (including his hair being touched), dogs, frowning, tea, anything sweet, Angel Dust's sexual remarks, being humbled, post-30s' technology, anyone ruining his outfit, being controlled and reminded of it, the idea of the hotel failing, and Mimzy bringing destruction to the hotel. For May's appearance (after Alastor turned into her), she is a 12 year old pokemon trainer girl who has an average height for a young girl and has long, chocolate-brown hair that has a single fringe at the center with three edges secured by a red and white bandana. She has blue eyes with long eyelashes with her single fringe on her brown long hair is nearly identical to Norman's (May's father). She wears a red short-sleeved shirt with a navy blue semi-circle on it, a yellow fanny pack, white gloves with navy fingertips, a white mini skirt over dark blue cycle shorts, and black ankle socks along with red shoes with black and yellow stripes. Despite her beauty, May is a sweet, very kind-hearted, optimistic, energetic, cheerful, and beautiful girl, who would love to eat desserts, try different foods in every town she visits and would help people in need. Like Misty, May can get very angry and hot-tempered at times when disagreeing with either Max (May's younger brother) or Ash Ketchum, but May is able to overcome her fear of Bug-type Pokémon. However, she can get very sad, especially when she loses a Contest, but does her best to prevail. She is also shown to have a side for romance, though on rare occasions. However, she became angry at her Munchlax because it was eating food that belonged to someone else and ran off when she didn't keep an eye on it, she had Max give Munchlax "pink surprise" in order to stop Munchlax's appetite and prevent it from eating. At the start of her journey, May didn't like Pokémon as she only wanted to start her journey just so she can travel and visit places. However, her encounter with Ash and Brock changed that and her love for Pokémon began to grow steadily. There should also be quotes from the characters in this story so we know what they're saying and what they're thinking.
