Summary
Fizz slowly pulls himself into a squat and tries to figure out why he’s in the guest room. It’s technically his bedroom, but he’s usually shacked up with Ozz these days. The only times that change are when Satan is visiting- always unpleasant, especially if he brings that little freak on his shoulder- or if he and Ozz are fighting. Much worse.
*****
Fizz wakes up with a headache. -

HELLUVA LOSS: ROLANDO'S RAMPAGE (Halloween Ghostfuckers 1 year special) by HelluvaScribe
Fandoms: Helluva Boss (Web Series), Hazbin Hotel (Cartoon)
31 Oct 2025
Tags
Summary
Happy Halloween…or should I say Unhappy Halloween. It’s been one year since Ghostf***ers came out and no Rolando merch has been seen since. He’s double dead to the Helluva Boss fandom now, while every other character continually gets merch, even Chaz who was a one-off villain like Rolando. The merch is a mess, especially now, and Helluva Boss is a shell of its former glory. Inexcusable and disrespectful. That’s why I made this in frustration…because in my opinion, no other character in the show can out-shadow this underrated villain. Enjoy this Rolandoween special…or don’t.

i want to love (and treat you right) by Spades (bumblingbees)
Fandoms: Helluva Boss (Web Series)
17 Oct 2025
Tags
Summary
Blitzø sighs, eyes trailing down to that serene mimic of Fizz’s face. He could turn it on, tell the bot to act how he wants. Make it cry, make it hurt. It’d be all a play for him, though, and that’s not what he wants.
He hates this fucking thing. Hates how wrong it is, how far removed it is from its inspiration. This isn’t Fizzarolli, this isn’t anything. Blitzø hates it, and even more than that, he hates himself for staying with it. Hates that his dick is already half-hard again just from looking at this pile of scrap metal and fake flesh, hates that he wants nothing more than to stick himself back in and cry into its fucking chest.

The Universe Where You Didn't Have a Not-Divorced Party by The_Great_and_Terrible_Lich_King

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)
23 Sep 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 let out a loud groan, staring down at the papers that laid scattered out on his desk, pen in one hand as he rested his chin in the other. His third hand’s fingers tapped against the wooden desk. Mammon’s eyes narrowed as he stared down at the paper he had on top of the pile of the others, sneering as he read the contract.
It was some stupid mother fucker asking for a part of his precious money in exchange for a piece of the ring, that he ruled over, so he could build another cheap attraction to squeeze as much money as possible from some idiot demons that most likely were tourists. Mammon felt anger swirl in his chest as he snarled, letting out a sour growl as his grip tightened around the pen, only seconds away from snapping it in half.
How dare these rotten creatures ask so much from him, he was Mammon for Satan’s sake, he was the embodiment of greed itself.
Mammon’s fists clinched up into balls as he let out an unpleasant growl, slamming the pen down onto the desk before snatching the paper up, harshly wading it up into a ball before flinging it into a nearby bin. He bared his teeth like a feral animal as a puff of green smoke fumed from his clenched fangs.

And Maybe Then You Wouldn't Get So Sick of Me by ItsBlitz, SilverServerError

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.
