"Echoes of the Black Widow: The Transformation of Alastor"

Prompt: Write the transformation story of Alastor (from the adults cartoon/animated series Hazbin Hotel) turning into a black widow spider (from real life) female, complete with gender change (turning from male into female), shrinking (making Alastor spider-sized), body changes (developing mandibles (instead of a jawed toothy mouth), losing vocal cords (making him unable to talk or make other sounds), his sides growing an extra pair of spider limbs (his arms and legs becoming identical spider legs), his eyes shrinking and multiplying into small black spider eyes, his posture completely shifting and falling from his previously bipedal posture to an eight-legged posture, a segmented spider body, his rear end (aka a butt or ass) and male genitals merging together and inflating into a huge spider abdomen (being filled with spider eggs to help raise baby spider by laying eggs, and Alastor starts laying eggs during the mind/mental changes), etc), age change, and mind/mental change (with Alastor's personalities and memories being completely replaced with a female black widow spider's personality and memories, with the voice inside his head telling him that he was never Alastor and never a demon to begin with and tells the newly-transformed being that he (now she) was always a black widow spider and that she has built her webs and she is about to lay her eggs, despite Alastor quickly losing her understanding of words or languages during the mind/mental change and is unable to know what the voice is saying due to Alastor becoming a simple and instinctive spider (words/languages are simply completely foreign noises to spiders and hold no importance to spiders, so the voice in Alastor's head is completely unclear to Alastor, now a female black widow spider queen), and despite Alastor's best efforts of holding onto her former memories/personality of being Alastor, completely turning her into a black widow spider female). 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 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). 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. For the female black widow spider's appearance (after Alastor turned into her), her body is 14–16 mm (1/2 inches) in length and is literally pitch-black in color, often with an hourglass-shaped red mark on the lower abdomen. She frequently hangs upside down near center of the web and waits for any insects to enter the web to attack. She bites her victim then wraps it in silk. There should also be quotes from the characters in this story so we know what they're saying and what they're thinking.
