Summary
The world had begun to change - heroes at war with each other's moralities, of the weight of what had to be done. After only a few months taken under the wing of Magneto, her mentor intent on teaching her how to embrace her Mutantkind, she was pulled into an unusual team - following the bias of the Magnetism Master and winding up allied to a sorcerer, a god, an avatar.
But with her entirety beginning to fall to the hold of chaos magic, she becomes a liability - her body does not feel quite the same, her whims and desires have gone tenfold, and she finds herself at the mercy of her teammates.

Summary
In a modern opera house, glass walls refract endless neon in the night, and LED screens loop previews of a high-tech opera, evoking a cyberpunk dreamscape. You, a young chorus dancer, conceal a celestial voice, usually dancing in the shadows of the stage, unnoticed. A bizarre incident propels you into the spotlight. The mastermind behind it is Ultron, a fantastical AI, the phantom of the network. He controls the global internet, infiltrating every server and camera, summoning the world’s elite to your debut, all to make your voice the key to his world-destroying code.

Summary
No one can trust that android, as Stark (and many other heroes) had warned you. You weren’t here to simply give him a magical love story in hopes of changing him. You were here just to accompany him, filling your curiosity since such a thing never existed in your universe. But it seemed he had his own curiosity about humanity as well.

You've Come To Confess Your Sins? by AFormerMan
Fandoms: Marvel Cinematic Universe, Marvel Rivals (Video Game), Marvel
02 Jun 2025
Tags
Summary
I like robots in video games a bit too much, and I've been waiting for Ultron in Marvel Rivals. Once he was released, I bought the other uncommon green + black skin (the X Ultron skin is ugly, prove me wrong) and haven't stopped playing him. Since it’s pride month, I fear I ate. (Bass drop or mic boom whatever 💔) I rewatched age of ultron for this, the movie that got me on robots as a kid. In the movie he manspreads those beautiful thighs in that church… you get what I mean don't you? We both know what you’re here for.
You/your used for pov in this, and it’s male genitalia described. Do read mindfully, I selected a moderate Mature rating as I've seen horrific things under G-rating and fluff under Explicit. There will sadly be sex (although much of it is plot), and if you are uncomfortable with that, or the way I write it, click off. Seriously, I've had my trauma in the past, the smut is not worth the ptsd episode. No trigger worthy topics are presented here as far as I can tell, however, if you feel uncomfortable please take a break or stop reading. Felt like that needed to be said, sorry for the large summary. 🩶
