The Universe Where You Didn't Have a Not-Divorced Party by The_Great_and_Terrible_Lich_King
Fandoms: Helluva Boss (Web Series)
14 Sep 2025
Tags
Summary
Blitz was fucked.
Which wasn’t unusual; he was always fucked, save the few times he was doing the fucking. Which was quite often.
Not only that but he was very good at fucking people over, not that that was always a separate activity. And it was this talent for fucking that got him into this business in the first place. That is, the murder business.
But it didn’t really matter if he had something with more bullets, or even the bazooka Blitz was also very found off.
Because tonight, need I remind you, Blitz was very fucked.
~
The Timeline where Blitz is less put together and Stella didn't hate her husband to a comical degree, only a reasonable degree. A fic that focuses on the start of Blitz and Stolas's relationship, the difficulties of running a cross-dimensional start up in Hell as an imp, Stella girlbossing, kids and adults making bad decisions, and a wee bit of revolution.

Helluva Boss: The Great Pirate War AU - The Sinister Siren by HelluvaScribe
Fandoms: Helluva Boss (Web Series)
31 Aug 2025
Tags
Summary
Inspired by the Great Pirate War AU Merch drop on August 18, 2025. Fueled by my rage of not seeing my favorite underrated villain Rolando part of the merch drop YET AGAIN! Another missed opportunity. I could’ve called it “Legend of the Golden Grimoire” or “Helluva Captain” or “Blitz’s Buccaneers” or just “The Great Pirate War,” but Rolando deserves to be in the title, so there.
Created August 18 – August 31 2025
Warning: “Helluva Boss The Great Pirate War AU” contains violence, drinking and sexual references, no modern swearing and Rolando. Viewer discretion is advised.

Summary
Mammon squinted his eyes, a silent judgment passing through them, “Enough playing with the toys, Fizzie. I wanna see these toys playing with you.”
“But, Sir-“
“Nobody buys the toy cause they wanna fuck a fake Fizzie. They buy the toy cause they wanna fuck you.”
Fizz’s gut clenched. Then what did it say about the Sin who commissioned them in the first place?
In which Fizz begins to work closely with Mammon. Very Closely.

Summary
Seven years after the fire that ended everything, Blitzo Buckzo has nothing going for him. He's miserable, lonely, and spends his days working at LooLoo Land for whatever pennies they're willing to offer. And yes, he fucks the park's RoboFizz. Regularly.
But after a new Fizzarolli AI update goes out to Hell's favorite sexbots, something in LooLoo Land's RoboFizz changes. When the robot that Blitzo had been using to fill the empty hole in his heart starts recalling the real Fizzarolli's memories, the imp is forced to face the events that he'd rather have left forgotten - as well as those that he'd rather die than forget.
Written for Cherri Bang 2025

Summary
It's hard to find work as a succubus if you want to avoid sex. As understanding as Asmodeus is, his Lust ring does have a certain feel that can't really be ignored. Work can be even more scarce when your life's passion is for radio and the majority of people who still own radios are in the area of a murderously-enforced one-station monopoly.
But for the radio-loving Erotovore Siv Phyllis, all that is about to change. Thanks to hell's least scrupulous tech mogul, a new station is about to go on the air in the Pentagram, and the flagship "Uncle C Show" is going to need a producer. As a result, Siv has found herself a steady job working with VoxTek - But with an unexpectedly alive host and a dangerously unscrupulous station manager, Siv is starting to suspect she's stepped into a trap where she's not sure if she's the target, or the bait.

In every universe, it's mine! by MazaikoMasi
Fandoms: Helluva Boss (Web Series), Hazbin Hotel (Cartoon)
02 Aug 2025

Summary
The world feels so small when fate wraps you up in invisible threads, and you’re dragged helplessly toward a love you can’t explain. For an imp like Blitzo, that pull was always obvious—some distant, gut feeling that kept leading him to the right place at the right time.
Still, he never managed to control it. It hit out of nowhere, totally random, and sometimes he pushed back—angry, confused, refusing to play along.Stolas, on the other hand, was a demon who’d seen a lot and heard even more. Magic ran deep in his family for generations, and thanks to their powers, they’d brought countless visions and prophecies to life.
But the universe—strangely enough—kept whispering just one prophecy, over and over, louder each time:“No matter where you are, in any world… he’ll find you.”

Summary
Inspired by the works of @JizokuArt
Content Warnings: Explicit sexual content, infidelity themes, strong language, alcohol use, fantasy violence, use of power dynamics in a workplace setting. Reader discretion is advised.
What happens when the ties that bind turn to chains—and those chains snap?
Moxxie is keeping a secret from everyone, even Millie, but that is not even the least of his problems. Tensions boil over in the chaotic confines of I.M.P, as Blitzo's unexpected reshuffling of responsibilities ignites a fierce rivalry—and an unexpected attraction—between Moxxie and Loona. When Blitzo delegates some of Moxxie's tasks to Loona, it sparks more than just professional competition.
For Moxxie, a forbidden romance with Loona feels like liberation until the walls come crashing down. Meanwhile, Crimson orchestrates a ruthless game, watching his son and his cronies spiral, only for things to unravel beyond even his control.
This isn’t a story of forgiveness or redemption—it's a brutal reckoning for everyone involved. And in Hell, there are no happy endings.

Secondly, this is my first time posting, so give me your impression of the chapters, whether positive or negative, but please make sure the criticism is constructive and correct.

The Best of Us Can Find Happiness in Misery by ItsBlitz, SilverServerError
Fandoms: Helluva Boss (Web Series)
13 Jul 2025
Tags
Summary
“Plenty of sockets to stick yourself in. You don’t need me.” Blitzo chanced a look back, heart falling.
It gathered its limbs into itself, the smile finally falling as it looked down at its singular foot on the asphalt. “If you don’t take me,” he looked up, “imagine who will.”
And as the ugly guilt reared its head, Blitzo felt bad. He felt sorry, shit, he felt responsible. He couldn't allow even this fake Fizz to experience half the bullshit he'd put himself through. He knew the type of sickos who lurked around the corners, who treated him like scum. Imagine how they'd treat something that had an artificial pulse and a hard drive full of sexual innuendos.
So he turned around and went for his under arm, lifting him up like a wounded soldier, and dragging him out of the dark without a second thought.

Blitzo finds a badly beaten FizzBot on his walk back home. He takes it back and gives it a jump.

Summary
Keep the audience distracted and you could get away with things right under their noses.
Which was how he’d gotten Blitzø between his thighs, separated from the rest of the patrons by a very thin curtain.
Despite his lack of reservation, Blitzø still gets dinner and a show.
