Korra's Transformation into Alastor

Question: Write the transformation story of Korra (from The Legend of Korra animated series) turning into Alastor (from an adult cartoon/animated series Hazbin Hotel), complete with gender change (turning from male into female), clothes change, height progression, age progression, reality change (Korra's world becoming the world of the Hazbin Hotel animated series), and mind/mental change (with Korra's personality and memories being completely replaced with Alastor's personality and memories, despite her, now his best efforts, making him completely forget that he was ever a human woman or an Avatar named Korra, only remembering that he was an overlord, as well as being "The Radio Demon", and his name was Alastor). For Korra's appearance, she is a brown-skinned woman of between 17-18 years old, a height of 5.7 feet (170 centimeters) tall, cyan iris colors in her eyes, and dark brown (almost black) long hair worn up in a pony tail. She wears a sleeveless outfit, consisting of a sleeveless light blue shirt and baggy blue pants tucket into brown faux swede boots. A brown swede fur-lined cloth is draped around her waste. For Korra's powers, she has impeccable athleticism and acrobatics, shown being capable of simultaneously lifting Tenzin and his children with relative ease. She has surprising speed that go along with her agility and reflexes, which make her a skilled combatant in and of themselves. Her physical strength and stamina makes her capable of swimming across large bodies of water for days, or lift and throw significantly larger opponents. She can punch with enough force to break iron pipes or shatter large chunks of ice launched at her. Her dexterity and balance allows her to skillfully dodge a large barrage of projectiles and easily leap across long distances and over high obstacles from a stationary position. She is shown to be quite flexible, able to bend and twist effectively enough to attack from various angles or squeeze through tight spaces. The series' creators consulted a professional martial artist in the design of the show's fighting system. Under the White Lotus' watchful protection, Korra was educated in all known academic fields, and trained by the best martial arts instructors. She was a fast-learner and considerable prodigy, seemingly driven. Eventually, she sought out training from Aang's original teachers—Katara, Zuko, and Toph—but had great difficulty under the mentorship of Aang's son, Tenzin. Her predecessor lived with personal grief over the genocide of his people, and his personal failure as The Avatar in his inability to prevent the century long world war that destroyed millions of lives. He had vowed "never-again" would he allow himself to be unprepared in his subsequent live(s), and Korra unconsciously channels this oath in her insatiable quest to master every known martial arts that exists in her world, including Mixed martial arts, Jeet Kune Do, Aikido, Baguazhang, Yang-style tai chi, Yin-style baguazhang, Hung Ga, Southern Praying Mantis, Southern Dragon kung fu, Changquan, Xingyiquan, and Wing Chun. As the Avatar, Korra is capable of bending all four elements (air, water, earth and fire). Even as a young child, she was already a child prodigy, able to bend them with ease since and displayed a level of proficiency that would have rivaled her predecessor, Avatar Aang. At the start of the series, Korra is proficient in water, earth and fire, but struggles with airbending due to the difficulties of embracing her spiritual side. She utilizes all elements equally, but favors each one for different strategies: airbending mostly for crowd control and non-lethal purposes, such as gliding and evasive manoeuvres; waterbending for both defensive and offensive manoeuvres; earthbending for strong attacks; firebending for raw "all-in" aggression. She learned metalbending, being the first metalbending Avatar. She also tends to use firebending when she is angered or acts with hostility towards an opponent, as she demonstrated when threatening the Red Lotus when expressing outrage to Zaheer for attempting to murder her father. After learning energybending thanks to Aang's spirit, she becomes capable of restoring bending to those who had blocked their abilities. Her duties as Avatar and her personal feelings towards people did come into play with the restoring power, as she did not grant bending abilities back to individuals with backgrounds in crime. During Harmonic Convergence she was able to use energybending to connect with her inner spirit and gain cosmic energy from the universe to project her giant spirit. As the Avatar, Korra is as a bridge between "Material World" and the "Spirit World", the plane of existence where the universe's disembodied spirits dwell. As her training under Tenzin progressed, she had slowly reconnected with her spirituality, seeing visions and accessing various memories from her past lives. Korra is able to purify "dark spirits" by balancing the energy within them. She learned to enter the Spirit World through the guidance of Jinora, her spiritual guide. Due to some residual traces of mercury in her body and mental pain after Zaheer poisoned her, Korra temporarily lost the ability to contact Raava and was unable to enter the Spirit World for three years, but regained these spiritual powers in the last season. As her predecessors, her most powerful ability is the Avatar State, in which she receives a massive boost in raw power from the cosmic energy, enabling her to easily overcome any opponent that tries to fight her head on. In the series it was revealed the Avatar State, and the Avatar itself, were created after the spirit of light Raava and the firebender Wan merged forever. In addition, this state allows her to access bending techniques she would not have learned during her own lifetime but throughout that of her past lives. If she is killed in this state, then this would cause the Avatar to cease being reincarnated. After the events of second season, Korra's Avatar State isn't able to access to the knowledge of her predecessors since she lost her connection to them indefinitely. However, she can communicate with Raava directly instead, something her predecessors were generally unable to do. For Korra's personality, and unlike her predecessor Aang, Korra is described as "very tough, very headstrong, and not scared to get into a fight." Her stubborn and hot-headed personality detracts from her talents, preventing her from easily learning airbending or connecting with the Spirit World. The Avatar traditionally has the greatest difficulty mastering the element diametrically opposed to the Avatar's personality. For instance, Avatar Roku—a firebender—took longer to learn waterbending and Aang—an airbender—took longer to learn earthbending. The waterbender Korra, on the other hand, had little difficulty with firebending but had considerable trouble with airbending, a situation noted to be spiritual and not elemental. Her best friend and animal guide is a polar bear-dog named Naga, whose strength helps Korra out of many dangerous situations. Although wild polar bear dogs were originally feared and hunted by Water Tribes, Korra is the first person to ever tame one. Korra is good friends with her pro-bending teammates, the brothers Mako (her romantic interest in seasons 1 and 2) and Bolin. She also develops a strong friendship, and later romance, with Asami Sato, a wealthy industrialist. Korra has strong relationships with the family of her previous life: Having learned waterbending from Katara and then airbending from Tenzin, Tenzin's children Jinora, Ikki, and Meelo look up to her as an older sister, and Kya and Bumi regard her as a friend. Korra is generally on good terms with her own parents, but has little contact with her uncle or cousins, whom she considers weird (and her father considers dangerous). Korra is unusual amongst her past lives in that she is technically royalty: her father Tonraq was in line to be the chief of the Northern Water Tribe before being banished and relocating to the South. Korra's character develops and matures during episodes 11 through 12 of the first season when she is confronted with detachment from her main three bending skills, leaving her only with airbending, which she had unlocked to save Mako from Amon. Later, she connects to her spiritual self through Aang. Once the connection to her Avatar predecessors is established, Aang is able to bestow energybending upon Korra (as well as her main three bending skills lost earlier). Although Korra is able to bend all four elements, while being capable of entering the Avatar State, Korra is still in the process of perfecting her airbending skills as well as having a true connection and understanding of her spiritual self to complete her training as a fully realized Avatar. Combined with the events of seasons 2 and 3 placing her in life and death situations, the former having her no longer able to contact her past lives for advice, Korra begins to suffer post-traumatic stress by the events of Book Four: Balance while doubting her abilities as the Avatar to maintain balance after those she faced have each disrupted the order she was struggling to protect in massive ways. But ultimately, once able to let go of the pain she went through and realizing the significance to her past suffering, Korra returns to her usual self while becoming a more kind, mature, compassionate, levelheaded, thoughtful and intelligent (and a bit more sarcastic) person from her ordeals. For Alastor's appearance (after Korra turned into him), 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 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. There should also be quotes from the characters in this story so we know what they're saying and what they're thinking.
