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.

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
“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
Blitzø starts the video, and it turns out to not be the pageant itself but afterwards, at a meet and greet. The video taker’s in the crowd, holding their phone up high to get a good shot of the winner in the middle of everyone.
They’re pretty. A cute beaky smile, with that same circle of red that the robot had. Black circles on his cheeks, a mismatched striped fool’s cap. Their movements are clunky, but their smile is so wide, and when they catch sight of the video taker’s camera, they look straight at it and grin, pink eyes crinkling in the corners and buck teeth untouched from childhood.
He’s alive.
or Blitzø thought Fizz died in the fire and spends 6 years mourning him. Then he meets the Fizzbot.

Summary
“Charming”, Blitzo said, tone dry. “Yeah, just so you're aware, I'm not interested in fucking you or any of that.” He paused for a moment. “Even if I was, I'd use my own lube. Either way, I don't care. Not into you.”
“Aren't you? My sensors can pick up on arousal, you know, and you seem to want me bad”, Fizz cooed, saccharine sweet, the last word dragged out teasingly.
“That's a lie. It didn't say any of that in the damn instructions.”
A bold claim. Not that he had read more than half a page of the damned thing.
“Oh, that's no fun.” Fizz pushed his lips forward, a mockery of a pout he knew all too well, causing his tail to thump against the sofa with irritation. “Turns out you're smarter than you l-look.”
Accepting a Robo Fizz Personal Companion as payment for a job was better than receiving no payment at all — or so Blitzo had thought.
