Resurrected and dropped into a 20th-century post-apocalypse ruled by monsters, Anna Valerious would become a terrifying wild card in this new world order. A skilled and fiercely independent monster hunter from the 19th century, she would be unburdened by modern morals and singularly driven to fight the "abominations" she encounters. Her arrival would ignite a desperate struggle for power and survival between humanity, Eve's monstrous creations, and Anna herself.

In an apocalyptic demonic human world, Princess Celestia's human form would likely be a corrupted or twisted version of her divine self, fusing her signature sun motif with imagery of damnation.

In an apocalyptic scenario following the "Joy virus" outbreak, Nicole Watterson would appear battle-worn and hardened, a stark contrast to her cartoon self. Driven by her relentless protective instincts, her appearance would reflect her journey as the last survivor, blending her innate feline traits with the grim reality of her new life. Faded fur: Her normally vibrant light-blue fur would be dull and matted from stress and lack of care. A few scars, likely from close calls with infected "huggers," would be visible through her fur. Worn clothing: She would wear a tattered version of her signature white shirt, now stained with grime and perhaps faded rainbow-colored fluid from past encounters. Her skirt might be torn or replaced with more practical, scavenged pants for better mobility and protection. Intense eyes: Her round, kind eyes would be narrowed and constantly on guard. They would show deep-seated trauma and exhaustion but still burn with her fierce determination. Her eyelashes would be clumped together, and her pupils would be dilated, always watching for threats. Feral characteristics: Her cat-like instincts would be heightened, evidenced by sharper, unsheathed fangs, twitching whiskers, and a low, ready-to-fight stance.

In Fate/Grand Order, Quetzalcoatl appears as a tall, blonde, white-skinned anime woman with emerald eyes and a kind "older sister" demeanor, though her true nature as the Feathered Serpent God of Mesoamerica manifests in her ferocious expression and connection to wrestling, leading to a split personality or a duality where she is both benevolent and terrifying, especially to her enemies. She wears Aztec-inspired clothing, including a plume on her head adorned with orange and green feathers, and her presence is tied to her powerful winged mount, the Quetzalcoatlus.

As a fan-made character, her appearance is not fixed but is usually depicted in a style consistent with the original Helltaker game. Fan artists often include elements like: Wings, horns, or other demonic features to fit the Helltaker world. Time-related motifs such as clocks or hourglasses. Clothing that might reflect her dual nature or power over time.

Hair: Her short, chin-length blonde hair would likely be styled in a more controlled, fashionable manner, such as a chignon or a neat updo to conform to Victorian standards of propriety. A stray fringe would still likely fall over her eye, but it would be a deliberate detail rather than a casual one. Complexion: Her naturally pale complexion would be emphasized, perhaps suggesting a life sheltered from harsh outdoor labor. Expression: Her perpetually sullen and impassive expression would be a natural fit for the era's photographs, which required subjects to remain still for long exposures. A black dress

When Beelzebub appeared for the first time in the game, she appeared as a grotesque yet terrifying fly beast with a white mane and a skull-like face. Most of the time, people can depict her design as an overweight gorilla with six arms and fly wings that was made to look like a fly as this was befitting to her nature as "The Great Fly" demon. However, if the Helltaker ends up encountering her in the Abyssal Void in the secret ending, Beelzebub appears as a refined lady with short and red white hair and long white horns that looked like a fly and much like other demons, she also has a black demon tail. In addition, she also wears a red refined tuxedo with red gloves and white fly-like buttons, a fly-like ribbon on her chest, and fly-like bracelets on both hands. In one of the scenes, Beelzebub unbuttons the top part of her tuxedo, which reveals her as being somewhat well-endowed.

Her blindness is masked by sunglasses, and she is known as the "Awesome Demon" and the former High Prosecutor of Hell.

Lucifer from Helltaker appears as a graceful, well-endowed woman with long white hair, red eyes, large white horns, and a black spiked tiara, wearing a businessman's suit over a red shirt with the Sigil of Lucifer on her chest. She is often seen with a glass of wine in her left hand and later adopts a more casual look with a black apron labeled "SATAN" over a red shirt for pancakes, her hair in a messy bun.
