Helluva Boss is an animated dark comedy series that has captured the hearts of fans with its edgy humor, stunning animation, and unforgettable characters. Created by Vivienne Medrano (VivziePop), the show is set in the same universe as Hazbin Hotel but carves its own identity through wild adventures, workplace mayhem, and complex character dynamics.
Whether you’re new to the series or planning your next cosplay, this complete guide to the main Helluva Boss characters will help you get familiar with the cast — and maybe even inspire your next Helluva Boss costume, including the iconic Helluva Boss Blitzo cosplay costume.
1. Blitzo (the “o” is silent)
Blitzo (pronounced “Blitz”) is the eccentric and loud-mouthed leader of I.M.P. (Immediate Murder Professionals), the assassination business at the center of the show. With his mismatched horns, glowing yellow eyes, and circus background, Blitzo’s personality is chaotic yet surprisingly sentimental.
If you’re planning to cosplay this fan-favorite, a Blitzo costume should include his signature red and black outfit, face paint, and devilish tail. It’s one of the most recognizable looks in Helluva Boss, making it perfect for conventions and photoshoots.
2. Moxxie
Moxxie is I.M.P.’s weapons expert and arguably the most rational member of the team. He’s a classic underdog character — intelligent, loyal, and frequently frustrated by his boss’s antics. Moxxie wears a suit and bowtie, and his relatively reserved look contrasts with the louder personalities around him.
His character is ideal for cosplayers who prefer more subtle styles. A Helluva Boss costume based on Moxxie can be achieved with sharp tailoring and face paint to mimic his impish features.
3. Millie
Millie is Moxxie’s wife and a fierce fighter. She’s warm, bubbly, and also incredibly lethal when the situation calls for it. Millie is a fan-favorite thanks to her devotion to Moxxie and her no-nonsense attitude in battle.
Millie’s outfit typically includes a torn red top and punk-inspired accessories. Cosplaying Millie requires dynamic energy, bold makeup, and attitude — she’s not one to be underestimated!
4. Loona
Loona, the receptionist at I.M.P., is a hellhound with a moody personality and a deep love for her phone. Although often sarcastic and disinterested, Loona has shown she cares deeply for the team, especially Blitzo, who sees her as a daughter figure.
Her look is a punk/goth aesthetic with black fur, red eyes, and spiked accessories — ideal for anyone into edgier cosplay. Loona’s design is also one of the most requested in Helluva Boss costume circles.
5. Stolas
Stolas is a demon prince of Hell and one of the more mysterious characters in the series. As Blitzo’s occasional employer and love interest, his presence adds depth and intrigue to the show. With his tall frame, regal attire, and hauntingly elegant voice, Stolas is mesmerizing.
A Stolas cosplay would involve detailed feather accents, royal colors (like dark blues and reds), and intricate face detailing to reflect his owl-like appearance.
6. Octavia
Octavia is Stolas’s daughter. Teenaged and cynical, she provides a grounded, emotional counterbalance to the chaos of Hell. Her relationship with her father is touching and gives Helluva Boss a more emotional layer.
If you’re looking to cosplay a lesser-known yet meaningful character, Octavia’s casual, grungy look and melancholy vibe make her a strong choice.
