WELCOME TO THE HELLAVERSE

The “o” is silent, but his antics are deafening. Blitzø is the loud, chaotic, and hilariously unhinged boss of I.M.P and a Hell-born imp with big dreams and even bigger issues. Originally a circus performer, Blitzø is now in the business of helping Sinners with their unfinished business on Earth by way of a good old-fashioned murdering. Despite his brash and hard exterior, Blitzø struggles with a traumatic past and deep insecurities, but when push comes to shove, he'll do right by his co-workers Moxxie and Mille, his adoptive daughter Loona and his maaaaybe boyfriend Stolas.

Blitzo’s messy quest for love and validation makes him the hot mess heartbeat of the series.

Moxxie is the anxious and lovable weapons expert of I.M.P. He's a theater nerd with a big heart, and has a moral compass that often leads to clashes with his coworkers, especially Blitzø. Despite his panic attacks and frequent at odds with his boss, Moxxie is a deeply loyal friend to both his coworkers and his badass wife, Millie, and will have their backs no matter how much trouble I.M.P. gets into. DON'T underestimate him—Moxxie has serious aim and even more serious sass when pushed too far.

Millie is the sweet-as-candy Southern badass and assassin extraordinaire of I.M.P. Don't let her adorable accent and bubbly personality fool you—she is a indomitable fighter with a fierce love for blood, chaos and her adorable imp hubby, Moxxie. You mess with Moxxie, and Millie will put you down. With her penchant for violence, Millie often worries that others see her only as the 'hired muscle' and is grateful to Blitzø for bringing her into the I.M.P. family where she was able to make friends and meet Moxxie.

Loona is the fiery, no-nonsense hellhound receptionist at I.M.P. with a cellphone in one hand and zero patience in the other. She is sarcastic, snarky, perpetually annoyed and would rather scroll through her feed than deal with her adoptive dad, Blitzø, and coworkers' work drama. When motivated, Loona brings fierce intelligence and street smarts to I.M.P's missions and will occasionally show a soft side to Blitzø, and others in need of true help like Octavia and Stolas.

Stolas is a flamboyant, Prince of Hell and bibliophile exiting an unhappy marriage and besotted with his beloved daughter Octavia. By day, he's a regal and dignified member of the Goetia family, and by night...well, he's usually tangled up in some wild inappropriate antics with Blitzø. Stolas often struggles with expressing his feelings and prioritizes his own desires over larger problems in his life, which gets him into more than a few misunderstandings with Blitzø and Octavia.

Fizzarolli is a flamboyant, acrobatic and sassy Imp who knows how to steal a show—literally and figuratively. Once a talented circus performer with Blitzø, his childhood friend, Fizz's life took a fiery turn when Blitzø set the circus ablaze and seriously injured Fizz in the process. Fizz didn't let this stop his rise to fame and continued to be a brand icon for Mammon, the toxic, scheming owner of Loo Loo Land. After reconciling with Blitzø and giving Mammon the boot, Fizz is now openly in a relationship with Asmodeus and the two run Ozzie's, a club in the Lust Ring.

The Disney-princess energy is strong, but make it Hell. Charlie is idealistic to a fault, determined to redeem the irredeemable. Her optimism is her superpower—and her biggest gamble. Her musical numbers and hopeful energy drive the Hazbin Hotel project, proving that sometimes the boldest rebellion in Hell is kindness.

If Charlie is the dreamer, Vaggie is the enforcer. She’s sharp-tongued, battle-ready, and the steady anchor in Charlie’s whirlwind. Together, they’re Hell’s ultimate power couple: heart and blade.

Voiced by Stephanie Beatriz (Brooklyn Nine-Nine, Encanto).

A spider demon who steals scenes and hearts with equal flair. Angel Dust’s sass and one-liners are fan favorites, but his deeper struggles give him real gravity. He’s proof that redemption is messy, loud, and sometimes hilarious.

Voiced by Blake Roman (Pokémon Concierge).

The Radio Demon: all smiles, static, and nightmare fuel. Alastor is charming in a way that’s equal parts vintage and villainous. He’s the ultimate wildcard ally—helpful when it suits him, terrifying when it doesn’t.

Voiced by Amir Talai (Kung Fu Panda: Legends of Awesomeness, Harley Quinn).

Your grumpy neighborhood bartender, if your neighborhood was eternal damnation. Husk is perpetually over it, but his loyalty sneaks out when you least expect it. Think “reluctant cat dad,” but make it Hell.

Voiced by Keith David (The Princess and the Frog, Gargoyles).

She’s cute, she’s manic, she’s probably reorganized your kitchen without asking. Niffty is chaos distilled into one tiny demon maid. A little unsettling? Yes. Endearing? Also yes.

Voiced by Kimiko Glenn (Orange Is the New Black, Spider-Man: Into the Spider-Verse).

The steampunk snake villain who never met a gadget he couldn’t over-engineer. Sir Pentious is all hiss and hot air, but his cartoonish flair makes him impossible not to love.

Voiced by Alex Brightman (Beetlejuice the Musical, Helluva Boss)—yes, he’s double-dipping in the Hellaverse.

Not all threats come from Hell—Adam, Heaven’s smug commander, proves that sanctimony can be just as ruthless. He’s stylish, cocky, and a perfect foil to Charlie’s redemption project.

Voiced by Christian Borle (Smash, Something Rotten!, Peter and the Starcatcher).

The King of Hell himself. Equal parts charming showman and intimidating ruler, Lucifer is also a dad trying (and sometimes failing) to connect with Charlie. His presence gives Hazbin its biggest emotional stakes.
