Loona is a hellhound who works as the CEO of her company, Boss Luv, with her best friend Suki as her assistant. One day, Loona (now Alastor) is visited by a demon, who offers her the chance to beco

Once upon a time in the underworld, Loona, the hellhound with her fierce demeanor and punk rock attire, was lounging around in the Helluva Boss office. Her large, dark grey tail wagged lazily as she scrolled through her phone, paying no mind to the chaotic background noise. However, unknown to her, dark forces were at play, drawing her into a vortex of transformation that would change her existence forever. It began with a low hum that seeped into the room like an unwelcome guest. Loona's sharp red eyes flicked up in annoyance, making contact with the eerie glow forming in the corner. She got up, her digitigrade stance allowing her to move with agile precision, and approached the glowing portal, black claws scraping gently on the floor. "What the hell is this?" she muttered, baring her pointy teeth as the hum grew louder. Suddenly, a force pulled her into the glowing circle, enveloping her in a shimmering cocoon of energies. Her body shuddered violently, and she felt an odd warmth spreading through her limbs. Her form began to change starting at her feet, which elongated and reshaped themselves into more elongated, human-like legs. Her black toeless stockings gave way to long black dress pants with bright red cuffs at the bottom. Her white fur with gray patches started to retract and vanish, revealing beige-colored skin over her arms and torso. Her crop-top disintegrated, replaced by a bright red dress-shirt with a black cross on the chest. Loona's characteristic spiked black choker melted away, replaced by a black knotted bowtie with a bright red center around her now emerging human neck. As the wave of transformation traveled further up her body, her upper body shifted, becoming more slim and dapper. Her hands, once clawed and padded, elongated into pale fingers tipped with red. Long black gloves with red at the fingertips formed around them. New memories began to infiltrate her mind. Memories of power, broadcasts, and dominance in Hazbin Hotel. The name “Loona” was slowly erased, and in its place, “Alastor” surged to the front. Her once fierce demeanor morphed into something more refined and unsettling. A broad, sharp smile took over her face, filling it with an eerie, unsettling joy. The final changes took over her head. Loona's long, voluminous silver hair retracted into a cropped, angled bob-cut with black tips, the style framing her face evoking the ears of a deer. Two small black antlers erupted from the crown of her head, and her pointed dog-like muzzle reshaped into a more human-like face with a sharp yellow grin. Her red sclera with white irises darkened into dark red sclerae with bright red irises. Black pupils turned into the shape of radio dials. A monocle appeared over the right eye, completing the transformation. Memories and personality immersed Loona completely, turning her mental landscape into that of Alastor’s. Where Loona once stood, now only Alastor remained, tall and imposing at 7 feet. Finally, Alastor—the Radio Demon—appeared in his complete form, clad in a red pinstripe coat with dark-red lapels that were now piped with white. He took a step forward, and his clicking hoofed toes sent echoes throughout the space. In his hand, a thin cane with a sentient vintage-style microphone materialized, ending the transformation as he twirled it with a devilish glee. Adjusting his black pointed-toe boots with a smirk, Alastor surveyed his surroundings. “What a splendid place!” he declared, voice sonorous and commanding. “Now, let’s bring some entertainment to this dreary realm, shall we?” In that moment, Loona ceased to exist; Alastor, the Radio Demon, had been reborn, fully embracing his new identity, with no recollection of ever being someone else.

The transformation took place on a particularly chaotic evening in Hell. Loona, the hellhound receptionist at I.M.P. (Immediate Murder Professionals), found herself wandering into a dark, eerie alleyway after an exhausting day filled with demons and mayhem. Unbeknownst to her, the alley harbored remnants of forgotten magic, power so ancient and potent that even Hell's denizens had grown to fear it. Loona, however, was too tired to care, her mind focused solely on getting home. As she trudged forward, a strange, glimmering portal began to materialize, crackling with red and black energy. Instinctively, Loona stepped back, a low growl rumbling in her throat. But the portal, as if sensing her hesitation, extended a tendril of dark magic, wrapping around her wrist and pulling her in. The world around her twisted and spun, a cacophony of sounds and visions blurring her senses. When Loona emerged on the other side, she found herself in a dimly lit room, the air humming with enigmatic power. She tried to step forward, but her body was rooted to the spot. A voice, charismatic yet sinister, echoed around her. "Ah, a new canvas," the voice drawled. "Time to reshape you into something more... fitting." Before Loona could react, she felt the magic envelop her, forcing her body to shift and change. Her sleek, hellhound form began to stretch upward, elongating as the familiar pressure of her bones shifting gripped her being. Her canine features melded into more humanoid ones, her muzzle retracting, leaving behind smooth, beige skin. Her fur retracted into her body, and her digitigrade stance slowly transformed into a bipedal one, her tail dissipating into nothingness. Her brilliant, white-silver hair caught fire in a riot of colors, melting into a cropped bob-cut with black-tipped ends, sleek and meticulously styled. Her once large, expressive eyes narrowed, the sclerae turning dark red as the irises became vibrant red orbs, glimmering with knowledge and malevolence. Black antlers sprouted from the crown of her head, growing to a subtle size. Loona’s clothing shifted, the tattered ensemble morphing into a refined, red pinstripe coat with ragged hems. Beneath it, a vivid red dress-shirt emblazoned with a black cross took shape. Her shorts elongated into black dress pants, accentuated with bright red cuffs. Black pointed-toe boots adorned her feet, red hoof prints marking their soles. The weight of transformation pressed on her mental state, a nebulous force replacing every memory, every personality trait she'd held. Her mind and soul underwent a radical metamorphosis. Memories of her life as a hellhound faded into oblivion, replaced by the twisted past and sinister experiences of Alastor the Radio Demon. Her proud personality, filled with sarcasm and loyalty, was obliterated and overwritten by the macabre, jovial charm of Alastor. The final touch was a monocle appearing over her right eye, followed by a bowtie forming at her neck, and black gloves materializing with crimson fingertips. In her hand, a thin cane appeared, complete with a vintage-style, sentient microphone at its end. It was done. In the dim light, no evidence of Loona remained as the transformation concluded. Alastor opened his mouth, and a deep, malevolent voice with an old-radio effect filled the room. "Oh, what a delightful change!" he chuckled, his sharp teeth gleaming with sinister joy. He twirled his cane, his memories and identity entirely those of Alastor, the infamous Radio Demon. No longer did he recall the life of Loona, the female hellhound. He only remembered being Alastor. Smiling broadly, he stepped forward, ready to bring his own brand of chaos back into Hell, utterly unaware of the life he once led just moments before.

In the shadowed recesses of Hell, Loona, the rebellious hellhound, lounged nonchalantly at I.M.P's office, mindlessly scrolling through her phone. Her day had been monotonous, filled with the familiar routine of chaos and occasional bursts of irritation. The fiery glint in her red eyes had dulled somewhat, an indication of her growing boredom. Unbeknownst to her, today would be anything but ordinary. In another part of Hell, a powerful spell was being cast by a coven of demons, their chants echoing through the infernal darkness. Their goal? To invoke the spirit of the legendary Radio Demon, Alastor. A crackle of energy sparked through the room where Loona sat, unnoticed in her disinterest. Suddenly, the air around Loona began to shimmer and warp. She looked up, eyes widening with confusion as the temperature plummeted and her surroundings began to distort. The room seemed to twist, the very fabric of reality bending to accommodate some unseen force. Loona's body shook, a deep, pulsating energy coursing through her veins. She tried to cry out, but her voice was lost in the maelstrom of dark magic enveloping her. Her form began to shift, bones cracking and reforming, fur receding, and her muzzle shrinking back into her skull. The pain was excruciating, yet she couldn't move, paralyzed by the intensity of the transformation. The once tall hellhound began to stretch, her limbs elongating as they restructured to a taller, more humanoid frame. Her white fur melted away, replaced by beige skin. Her red eyes flickered, the sclera darkening to a deep red while her irises brightened to a chilling crimson. Loona's voluminous hair shortened and changed color, becoming a cropped, pinkish-red bob with black tips. The silver fluffiness was replaced with sharp, defined angles. Two black antlers sprouted from her head, curving upward majestically. Her canine teeth reshaped into a human-like set, yet retained their razor-sharp quality, framed by a broad, unsettling smile. As the transformation reached its climax, her outfit morphed along with her body. The tattered grey crop-top and shorts dissolved, replaced by a striking red pinstripe coat with dark-red lapels, a bright red dress-shirt with a black cross, and long black dress pants. She – now he – found his hands adorned with red-fingered black gloves, and his feet shifting into black pointed-toe boots. A monocle materialized over his right eye, and he felt the comfortable weight of a cane equipped with a vintage microphone in his grasp. The final change was perhaps the most profound. Loona's mind, with all its memories, attitudes, and experiences, began to change. The rebellious, sarcastic hellhound's essence was slowly overwritten, replaced by the dark charm and malevolent glee of Alastor. Her – now his – mental landscape completely reshaped, erasing every trace of his past life as Loona. The newly-formed Alastor straightened, the fog of transformation clearing from his mind. He let out a satisfied chuckle, his voice resonating with an eerie radio static undertone. Alastor looked around the office, now an alien environment to him, and smiled wider. The once juvenile defiance and irritation were replaced by a calculated, sinister cheerfulness. “Well, well, well,” Alastor mused, his voice disturbingly pleasant. “I suppose this is a rather amusing twist on this hellish day.” With a jaunty step, Alastor exited the office, his mind already whirring with thoughts of new conquests and entertainments. The Radio Demon had returned to Hell in the most unexpected of ways, with the memory of being Loona the hellhound wiped clean from his existence, leaving only the mischievous, terrifying persona of Alastor behind.

Loona paced back and forth in the office of the Immediate Murder Professionals (I.M.P.). Despite the chaos that usually engulfed her life in Hell, there was an unusual stillness today. Blitzo, Millie, and Moxxie were all out on a job, leaving her alone with her thoughts. She flicked her tail anxiously, her mind restless as ever. Perhaps spending so much time in the human world had gotten to her, or maybe it was the nagging feeling that something was about to happen – something she couldn’t quite put a paw on. Suddenly, the air around her shimmered, distorting like heat waves rising from hot asphalt. A strange, crackling sound akin to radio static filled her ears. Loona’s fur bristled, and she let out a low growl, ears flicking in agitation. “Who's there?” she barked, her eyes darting around the empty office. But there was no answer. The shimmering grew in intensity, and Loona felt a strange tug at her very being, as though an invisible hand was pulling her from every direction. Panic flared in her chest as the world around her melted into a swirl of vibrant, disorienting colors. She tried to scream, but her voice was swallowed by the static that now buzzed, louder and louder, bursting inside her mind. Her body began to change, starting with her height. She felt herself stretch, bones elongating, muscles and tendons painfully rearranging themselves. Shaking, she watched in horror as her once-voluminous silver hair shortened and turned a deep crimson, the tips shading into black. Her facial structure contorted, her previously pointed, wolf-like muzzle retracting into a more human-like visage. Beige-colored skin replaced her fur, and memories began to slip away. “No!” she wanted to shout, but now her mouth was forming an out-of-place crooked smile, filled with sharp, yellow teeth. The static in her mind intensified, drowning out her thoughts, replacing them with foreign whispers and laughter. Eyes that were once white with red sclera faded to bright red irises within dark-red sclerae, full of manic energy. Alastor’s memories filled the void, obliterating any trace of who she once was. Experiences of a life filled with malevolence, a twisted sense of humor, and an insatiable hunger for chaos flooded into every corner of her consciousness. Her clothing morphed next, the tattered grey crop top and shorts melting into a dapper red pinstripe suit, complete with a monocle over her right eye and black gloves with crimson tips on her fingers. She sprouted small black antlers from atop her head, and his distinctive black-tipped tufts of hair replaced her ears. Finally, the long spiked black choker she wore shrank into a stylish black bowtie centered with bright red, wrapped around an impeccably tailored crimson dress shirt. As the transformation completed, the final echo of Loona’s consciousness was snuffed out, like a candle extinguished by a cold wind. Alastor blinked, the static finally clearing from his mind. He straightened, a wide, sinister grin spreading across his face. He looked around the unfamiliar office, immediately unimpressed by the lack of style. With a flavor of haughty confidence, he adjusted his monocle and tapped his thin cane, affixed with a sentient vintage-style microphone, against the floor. The office hummed to life with a haunting jazz tune. “Well now, this is quite a peculiar place,” he mused aloud, his voice carrying the crackling warmth of a vintage radio broadcast. His memories aligned to fit his surroundings, recalling the reason he was here: to spread his particular brand of mayhem. The door to the office creaked open, and Blitzo, Millie, and Moxxie stepped in, bewildered by the sight of the Radio Demon standing where Loona should have been. “Loona?” Blitzo asked hesitantly. Alastor's gleeful laugh filled the room. “Oh, dear Blitzo, I think you’ll find there has been a bit of a change of plans. It seems Loona has... vacated the premises, and I have gladly taken her place.” With a bow and an elegant flourish, Alastor stepped forward, eyes gleaming with red irises. “Now, how can the Radio Demon be of service?” And so, the I.M.P. would have to adapt to this unexpected twist: their hellhound receptionist now fully transformed, in body and mind, into the infamous Alastor. Loona was gone, her memories and persona obliterated, replaced by the ever-smiling, ever-mischievous Radio Demon, who only remembered ever being Alastor.

Legendary transformations are whispered across generations, but none so peculiar as the one of Alastor, the infamous Radio Demon of Hell. It encompassed a gender, age, height, and even mental alteration, making it a tale worth telling. The transfiguration commenced with Loona, the feisty and independent hellhound from Helluva Boss series, a wolf-like creature with raven-black winged eyeliner, red-sclera eyes, and a dark attitude to match. She began to feel a strange sense of disorientation, where her usual consciousness was gradually eclipsed by confusing, unfamiliar thoughts. Her rebellious spirit started to dissolve, slowly taken over by charismatic humor, elusiveness, and an unsettling charm characteristic of Alastor. Simultaneously, Loona's body began to contort and reshape. Her toothy muzzle softened, transforming into a human-like countenance. Her fur receded, replaced by beige-colored skin. The ragged edges of her soft, dark-grey ears became smooth, transitioning into hair - a pinkish-red, angled bob-cut with black tips at the ends. Gradually, large, black-tipped tufts of hair grew from the top of her head, mimicking the ears of a deer, while small, black antlers sprouted from the crown. Meanwhile, her dark grey nose morphed into a human one, and her piercing red eyes turned darker, with a blood-red hue and razor-thin pupils. As she grew taller, reaching about 7 feet in height, her proportions evened out, making her seem unexpectedly slim and dapper. Her grey and white fur turned into human clothes, a flamboyant dapper ensemble of a red pinstripe coat with dark-red lapels and a sharp blood-red dress shirt underneath, all matching the color theme of Alastor. Loona's tail disappeared, her clawed feet and hands altering to form red-hoofed toes and fingers, the color a stark contrast against the black gloves she was wearing. The dark, oval-shaped monocle over her right eye and the thorny black bowtie appeared, signifying the completion of her physical change. With the physical change complete, Loona's mind finally succumbed to the mental metamorphosis. Alastor's memories, his humor, his etiquette, and his taste for music filled him. His mind momentarily reeled at hearing a voice he knew not his own, but soon adjusted, accepting these vociferities of memory as his own. The memory of Loona, the feisty hellhound, was removed in entirety, replaced now with the history of one Alastor, the Radio Demon. As the astounding transformation drew to a close, a thin cane bearing a sentient vintage-style microphone manifested in his gloved hand. His unfathomable joy echoed in the absurd sound effects that he played through his microphone, announcing his presence and heralding the birth of a new personality. Every single strand of Loona had now morphed into Alastor, completely erasing her existence from her body and mind. Now, he's set for a fresh journey, fully equipped with a whole new essence of Alastor to broadcast new tales in the underworld.
