Verosika Mayday is a succubus demon and a famous popstar in both Hell and the living world.

She is Blitzo's ex-girlfriend and a recurring character in Helluva Boss.

Verosika is a tall, hot pink-skinned succubus demon with an hourglass figure. 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.

Her eyes have white-outlined light pink irises, yellow sclera, slit pupils, long and thick eyelashes protruding from them, and a small heart-shaped beauty mark under the right eye. She also has knee-length hair colored in ombre-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 mouth sports black lips and small fangs inside.

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. Despite being Succubi, Verosika and her group appear to have certain standards when in comes to sexual partners.
