    Summary

    Robotnik and Stone, a month into their relationship, planned to have a nice Valentine's Day out with each other tonight. Agent Stone from the future, mad with grief and willing to do anything to get Robotnik back, also has plans for him tonight, and isn't afraid to crash a party. Kidnapping him to shape into the man he remembers him becoming, Agent Stone has to chase himself through time and space before the Ivo he loves is changed forever.

    A collaboration with JustALittleAuthor, this is my unique take on this story we're shaping together, a "what if" parallel that exists side by side with their fic.

    Summary

    But Maria knows better. What her cousin really needs is someone special — maybe a new friend, maybe even a boyfriend.

    Sometimes, a family can just be a hedgehog, his human sister, their genius cousin, cousin's sycophant/syco-(boy)friend and a scientist grandfather.

    Summary

    Ivo Robotnik returns from the Mushroom Planet with one goal: vengeance.
    He’s ready to make the world — and Stone — pay for abandoning him.
    But instead of finding a broken assistant begging for forgiveness, he finds… a mortgage, a cozy kitchen, and a small child who calls Stone dad.
    Turns out, revenge gets complicated when your ex-minion apparently had your baby.

    Summary

    After a self-imposed mission gone ever-so-slightly wrong — not that the Doctor would ever admit any of his plans ever going wrong, Stone thinks with no small amount of amusement — Stone realizes that he and the Doctor only have one real option if they want to evade their pursuers. And between pretending to kiss his boss in the oversized coat closet and letting themselves get caught, Stone knows which one is infinitely preferable.

    ...even if Stone's real preference would be to actually kiss the Doctor. Beggars can't be choosers, and all that.

    Summary

    Set 15-20 years prior to the first Sonic movie, Doctor Ivo Robotnik (42) is studying his 3rd doctorate and studying hard. An academic, certified weirdo, and outcast. As he has been all his life. He’s used to it. Besides, humanity doesn’t deserve his attention anyway.

    Aban Stone (23) is studying a Bachelors in Engineering and taking on a multitude of extracurriculars, electives and club commitments. He’s friends with just about everyone with a foot in the door of every clique on campus. Jocks, nerds, theatricals, and everyone in between. He does what he must to fit in.

    When the pair meet, Stone is instantly enamoured. As is the doctor, though it takes him longer to realise. Robotnik had never been worthy of love and affection. He thought the experience was simply not in the cards for him. But now Stone has shaken his entire understanding of self, he’s bombared by thoughts, feelings, and hormones—yuck—that he’s never experienced before. Stone has dissolved Robotnik’s perfectly developed, trained, and genius brain to that of a prepubescent teen. Stone has him feeling so disgustingly high school.

    Summary

    Robotnik has Hanahaki disease, he coughs up lavender and he is very much not happy about it. It is later discovered that Stone’s favorite flower is lavender.

    Ivo had been coughing up little flower petals for weeks, at first it had been just an annoyance, but now it was really starting to get on his nerves. Looking down into the fist full of petals he found himself confused, why is he coughing up petals, why did they have to be the most disgusting flowers in the world, they smelt like a spiritual guru’s asshole, and tasted even worse. How people found them calming was beyond himself.

    After a little research Ivo realized this deadly disease is something called Hanahaki disease, an infection of unrequited love where spores take over the lungs and bloom flowers.

    Unrequited love? Ivo had no such thing! He’d never loved anyone, and he would never give anyone his time like that, they didn’t deserve it. No. This had to be a mistake, however he couldn’t stop himself from watching his sweet agent care for him and clean the blood from his lips.

    Summary

    The first story is an origin story for my OC, after I got back into Sonic the Hedgehog following the movie universe.

    A rabbit, a mad doctor, his too‑loyal assistant, and two incompetent robots walk into a lair… Sandi’s curiosity lands her in Robotnik’s clutches, where dinner plans turn into theatre, loyalty turns into conflict, and survival means keeping her defiance alive.

    The story is set 15 years into the future for my character's backstory. Robotnik has been in hiding with Agent Stone and rebooted Scratch and Grounder in an underground lair. How quaint. He's gone stir crazy and hasn't seen anyone else in years, so of course, it's going to be completely normal.

    Summary

    Most of Doctor Robotnik’s pride in his life came from the things he created. Numerous projects that would put the most valued scientists to shame, that is where he found most of his joy.
    His most beautiful creation, however, came from a collaboration between himself and his husband. A beautiful child.

    Robotnik and Stone have a daughter who wants to carry on her fathers’ legacy.

    Summary

    Dr. Ivo Robotnik was never jealous. He knew everything; he was a genius, after all. Such human emotion was beneath him. No living, breathing thing could ever get close to his level of superiority. So what if another agent from Stone’s past suddenly gets thrust back into Stone’s life? So what if that agent is not only arrogant but also conventionally attractive? So what if the agent was obviously attracted to Stone? And so what if that same agent had tried to get into the agent’s pants? None of that mattered; the stone was working like normal, and that was that… until it suddenly did…

    This is currently on hiatus due to my working on another fic that you can find on my profile!

    Summary

    He turned to face Robotnik, his hardened expression instantly softening back into the one he reserved only for him – with eyes wide, and lost like a puppy, instead of cold and sharp like those of a wolf - but not before Robotnik was able to catch a glimpse of it anyway, and suddenly, the genius was momentarily reminded of the wild animal that allowed itself to be kept docile under his thumb.

    It was an easy fact to forget, Thought Robotnik, and given the agents rather submissive tendencies, and unwavering devotion - towards him, at least - it was one he often did…
    But don’t let the doe eyes and innocent smile fool you, for despite the doctor’s treatment of him as such, it was no spineless runt that G.U.N had saddled him with. Oh no, no no. Not his agent. Not in the slightest.

    Summary

    Stone's always been... diligent... in protecting Robotnik. Physically, but also emotionally. He's lucky the men he's killed have been criminals and/or attempting to hurt his darling, because how would he explain this?
