Verosika Mayday (voiced by Megan Fox) is a major character in the adult animated black comedy romantic drama web series Helluva Boss. She is a famous succubus demon and pop star in both Hell and Earth. She is Blitzo's ex-girlfriend; she has a massive grudge against him after he broke up with her, which also deeply hurt her emotionally. She is also Vortex's boss.

• Verosika Christine Mayday is her full name; her nicknames are Miss Verosika (by Moxxie), Boss (by Vortex), Ver (by Blitzo), Unoriginal Pink Condom (by Blitzo), Whore (by Blitzo), Sloppy Bitch's Drunken Whore-Ass Face (by Blitzo), Sister (by Blitzo), and Miss Loosey-Goosey (by Blitzo).

• Verosika's voice sounds like April O'Neil from the superhero action film Teenage Mutant Ninja Turtles (2014) and its sequel Teenage Mutant Ninja Turtles: Out of the Shadows (2016).

• Verosika's sexuality is pansexual.

At some point in the past, Verosika found fame as a pop star, and at another point she started dating Blitzo. However, he wasn't a very good boyfriend, though, as he made their sex life very one-sided, but despite this, Verosika stayed with him. She eventually told him that she loved him, which prompted Blitzo to run away, steal her car and joyride to the Wrath Ring, max her credit cards to pay for horse riding lessons, and leave Verosika to pay for the hotel room they shared, effectively ending their relationship.

Sometime after this, she hired a hellhound named Vortex to be her bodyguard.

At some point, Verosika checked into rehab to recover from her drinking problem. It's implied that she encountered Blitzo's sister, Barbie Wire, during this time. Thanks to her celebrity status, Verosika was eventually let out of rehab.

Verosika is a tall and slim, bright hot pink-skinned humanoid succubus demoness with a curvy hourglass figure and a huge bust, giving her a slender and voluptuous physique. She sports a long, black-tipped spade-shaped tail and a pair of black-tipped horns on top of her head with black star designs on them, the left one taller than the right. She also has a pair of bat-like wings on her back with black markings that resemble heart shapes and has a heart-shaped navel.

• In her human disguise, Verosika takes the appearance of a light brown-skinned woman, with her eyes now having white sclera. Her long hair is ombre blonde with pink undertones from darker to lighter towards the tips, along with auburn roots and a light pink streak down the length.

• She appears noticeably taller in her human disguise than her regular appearance, and her arm tattoo does not appear in her human disguise.

Her eyes have white-outlined light pink irises, yellow sclera, slit pupils, long and thick black eyelashes protruding from them, and a small heart-shaped beauty mark under the right eye. She also has long, knee-length hair colored in ombré white, with pink undertones from lighter to darker towards the tips, and a darker-colored stripe across her bangs.

On her right arm is a red heart tattoo with Blitzo's name on it that has been crossed out by a thick black "X." Her makeup features both thick black mascara and black eyeliner, along with black lipstick—her mouth having small fangs inside.

Verosika has massive, perfectly round breasts (K-cups) that sit high and firm on her chest like gravity-defying spheres. They're large enough to strain against her tight outfits (think deep cleavage spilling out of that black-and-white strapless minidress), with a soft, plush bounce when she walks or performs. Unlike most succubi, Verosika has the ability to lactate sweet, warm, and creamy breast milk; her supply of breast milk is endless. The skin is smooth and flawless, bright hot pink; nipples are a darker rosy shade, perky, and sensitive—ideal for her seductive performances and intimate encounters. They have that ideal teardrop-round fullness: heavy but perky, filling a palm (or more) with pillowy softness on top of underlying firmness.

Her ass is thick, heart-shaped, and prominently juicy—wide, plump cheeks that jiggle enticingly with every step or tail sway. The heart shape comes from the way her hips flare out dramatically before tapering into her waist, creating a perfect shelf-like protrusion. It's soft and cushiony to the touch but toned underneath, with smooth skin that begs to be grabbed. In motion (especially during her stage performances or when she's strutting in heels), it has a hypnotic sway and ripple.

She possesses wide, breedable hips that emphasize her fertile, hourglass silhouette—dramatically wider than her already narrow waist, giving her that exaggerated, demonic, fertility look. Her thighs are thick and powerful yet soft, with a thick, pillowy inner gap that squeezes together invitingly when she stands or walks. They're plush enough to smother or wrap around someone, with smooth bright hot-pink skin and just the right amount of give—strong from her enhanced demon physiology but irresistibly squishy.

As a succubus, Verosika's pussy is perfectly smooth, slick, and hairless—permanently groomed to an immaculate, glistening state. The outer lips are plump and puffy, forming a tight, inviting seam that parts easily to reveal hot, wet pink inner folds. It's perpetually aroused and self-lubricating (a succubus trait), always slick with her sweet, intoxicating demonic juices that enhance her sexual inducement powers. Tight yet accommodating, with excellent elasticity and a velvety, gripping texture designed to milk and please. It has a subtle, natural glow or warmth that matches her seductive aura.

Verosika's primary outfit features a black choker and a tightly fitted, black and white strapless minidress with contrasting "X" and "O" shapes on the chest, as well as a star design at the abdomen and a sweetheart neckline. She also wears black thigh-high leg sleeves with three hot pink "X" designs down the sides and black high heels that sport a vague heart motif. She accessorizes with a set of white arm-length gloves, the right having the same "X" patterns as her leg sleeves (albeit thinner); a pale pink fur coat, which vaguely matches her hair; and a pair of round gold-framed shades, which have pink heart designs on each of their maroon lenses.

• In her human disguise, Verosika wears a white-trimmed, two-piece pink ruffled minidress—her crop top sporting long sleeves, with her right sleeve being detached, while her high-waist miniskirt's ruffles are colored in a slightly darker shade. The skirt also includes a white star design on the front and a black heart on the hip, along with dovetails that form into a light pink sash with slightly darker-colored ruffles and a heart design that visually references her tail. She also wears the same choker, thigh-highs, and heels as before, minus the 'X' cutouts.

Verosika's party outfit features ripped and torn, low-rise white jean pants with a black spiked belt and a matching black spiked choker collar; a dark purple crop top with a cleavage window, a long left sleeve, and no right sleeve with a matching dark purple forearm-length fingerless glove on her right hand. She wears her hair in a slightly messy, very long, high, calf-length ponytail with a black hair tie and wears dark purple high-heeled calf-length boots with hot pink "X"-design-like laces; for makeup, Verosika wears shiny light pink eyeshadow on her eyelids.

Verosika's swimwear outfit features a luxurious black micro-bikini that accentuates her curvy hourglass figure and large bust. The top consists of tiny black triangle cups made from shiny, high-quality fabric with a slight wet-look sheen. The cups provide minimal coverage for her enormous K-cup breasts, resulting in significant overflow and deep cleavage, held together by thin black strings tied around her neck and back. Small gold and hot-pink metallic heart and star charms dangle from the center and string junctions, matching her signature pop-star motif. The bottom is a matching low-rise micro-bikini with high-cut sides that sit extremely low on her wide hips, featuring a small front triangle and a thong-style back that leaves most of her large, rounded backside exposed. Thin adjustable side ties with identical heart/star charms complete the look. She pairs the bikini with her black choker (featuring a small heart pendant) and black high-heeled sandals with heart motifs and often has her long ombre-white hair styled in a voluminous ponytail or left flowing with strands cascading over her chest. A light application of shimmering body oil gives her hot-pink skin a seductive glow. Her black-tipped spade tail frequently curls around her thigh, drawing further attention to her thick thighs and hips.

As a succubus demon, Verosika is actively seductive and flirtatious, attributes she integrates into her famous popstar persona as a means of manipulation. Despite her status as a star, her fame, and her confidence, she also appears somewhat jaded and is nursing a drinking problem, something she has previously been to rehab for.

Verosika is highly competitive, but she also is petty and mean-spirited. She doesn't take losing well, particularly to Blitzo, with whom she shares a romantic history—a relationship that did not end well, leading to her bitterness and pettiness towards him. In "Apology Tour," when she and Blitzo spoke, she revealed that she truly loved Blitzo and was embarrassed for being vulnerable and saying she loved him and him bailing on her, which resulted in her bitterness and anger towards him. But, on one end, she truly wants to see Blitzo change into a better person, and, while she may not forgive him entirely, she slowly began to lose the bitterness she felt towards him, even offering him a slice of cake while also teasingly calling him a "fuckwad." In "Mastermind," Verosika showed great concern and horror when she saw him about to be executed.

Despite being succubi, Verosika and her group appear to have certain standards when it comes to sexual partners. This is shown when they cringed and groaned in disgust at the thought of pleasuring the cops after they were arrested at the end of "Spring Broken."

In "Apology Tour," she showed that she empathizes with others. She is willing to help people who have been hurt by Blitzo like herself cope, albeit unhealthily, by throwing a party dedicated to hating Blitzo. She even encourages Stolas to speak out on his feelings after being hurt by Blitzo, calling him the "freshest ex."

Demon Transformation - Verosika can transform into a larger "full demon" form at will, the silhouette of which can be seen when she and her gang cornered Moxxie in their newly rented office.

Human Disguise - Verosika can take on a convincing human appearance to disguise herself in the living world.

Sexual Inducement - Verosika has the ability to trigger a human's sex drive with her singing voice, touch, and even just her presence. Humans in her vicinity become extremely amorous and seek to make sexual contact with those around them, including Verosika's gang of succubi. This power appears to only actively affect humans, as demons such as Hellhounds near her retain control of themselves and their senses, whether they are using a human disguise or not.

Musical Talent - Verosika is a gifted singer. This skill can amplify her seductive power and induce humans who hear her to fall under her amorous charms.

Enhanced Strength - She was strong enough to kick a bar off of a house stair railing.

Blitzo is Verosika's ex-boyfriend. It is suggested that the pair enjoyed a sufficiently serious enough relationship that Verosika had a tattoo of Blitzo's name placed on her arm, subsequently crossed off following their breakup. In "Apology Tour," Verosika revealed that in the past she genuinely loved Blitzo, but he abandoned her upon hearing her truly confess her feelings for him, which was the first step that led to their breakup. It is stated that the duo eventually broke up after Blitzo stole Verosika's car, took it on a joyride, and abandoned Verosika to pay for a hotel bill while maxing out her credit card on horse-riding lessons, probably being the final straw in their relationship.

Following an encounter outside of Blitzo's office, Verosika dedicated herself to insulting and aggravating Blitzo at any opportunity, with Verosika rendering no positive comment towards Blitzo. Verosika's hostility persists into a second chance encounter in "Ozzie's," with her proceeding to publicly taunt Blitzo through song, in this encounter she claims that Blitzo is a selfish, reckless, heart-breaking freak, while implying she was genuinely deeply hurt by their breakup, which only exacerbates her hatred of Blitzo.

Verosika's resentment became so great that she hosts a party annually on Halloween eve in the human world, where she invites numerous people who were harmed and left by Blitzo. In "Apology Tour," Verosika ran into Blitzo at her "Anti-Blitzo" party, arguing with him about their breakup and refusing to receive his rather sarcastic apology for everything he made her suffer. She then opened up to Blitzo, claiming to feel like a bad person for continuing to hate him long after he abandoned her and was honest with him, admitting that she was only looking to help the people Blitzo hurt to help them get better. The talk made Blitzo reveal that he genuinely wanted to stop pushing away the people he loves and to change for the better, surprising and pleasing Verosika with his search for change and redemption. She then advised him about facing his situation with Stolas and offered him a piece of cake before leaving.

In "Mastermind," despite her previous history with Blitzo, she was worried and terrified when she saw that Blitzo was about to be executed for using Stolas' grimoire.

Verosika appears to have a dislike towards Moxxie due to his association with Blitzo as his subordinate. She had no qualm with sexually assaulting Moxxie with her posse after Moxxie attempted to negotiate with Verosika on Blitzo's behalf. In "Ozzie's," she does not join Asmodeus and Fizzarolli in mocking and insulting him. This suggests her dislike of Moxxie may only be due to him having tried to defend Blitzo or that she did not feel compelled to join them.

Vortex is Verosika's bodyguard. Their relationship appears to be professional, though they do also appear to be on friendly terms, with Vortex smiling at her and Verosika calling him Tex, which Vortex mentioned to Loona is a name only his friends call him, though by his word, she doesn't seem to pay him well enough for doing his job. Despite this, he is willing to sing with her, as seen during the song All 2 U (Motherf*cker) in "Apology Tour."

Verosika indirectly met Stolas at "Ozzie's," where she humiliated Blitzo for their failed relationship while Stolas looked on in confusion and shock. After learning of the recent "break-up" between Blitzo and Stolas, Verosika invites the prince to her party in the human world on Halloween to celebrate their hatred of Blitzo. Verosika treats Stolas friendly at the party to help him move forward after his "breakup" with Blitzo and decides to cheer him up, convincing him to tell his story with Blitzo. While talking to Blitzo about his quest to change, Verosika proudly notes that Stolas had a hook-up at the party and eases Blitzo's jealousy, advising him to allow Stolas to feel joy.

Verosika appears to know of Barbie Wire (Blitzo's twin sister) and her being in rehab; however, it is currently unknown what their relationship is like, if any. When Verosika encountered Blitzo in "Spring Broken," she insinuated that due to Barbie being in rehab, she was a "sad loser wash-up."

Her posse/crew (succubi and incubi) follows her lead professionally with camaraderie during performances and schemes, sharing her seductive, competitive nature. Overall, Verosika’s connections often revolve around her lingering pain from Blitzo, her supportive side toward other victims, and her commanding presence as a star.
