    Summary

    It all started with an episode of La Ultima Pasion. While the telenovela didn’t include henchmen, male pregnancies, or even blue, supercharged hedgehogs, it most certainly gave Robotnik his best idea of late:

    Producing an heir.

    Summary

    And one night, as they both sat working on a new project, Robotnik looked at him from across the lab. It was an incredibly silent moment. His gaze was softer this time, not mockery, just a strange, unexpected familiarity, as if they had known each other for decades. "Stone," he began quietly, "you won't leave my side, will you?" It wasn't a question, more of a command.

    Stone looked at him with a calmness he thought he'd never felt before. "Doctor," he replied, "my loyalty is unwavering. Wherever you go, I will follow."

    A detailed story about Agent Stone and Doctor Ivo Robotnik's relationship from the beginning till the end.

    Summary

    "The Master Emerald had abilities that even the doctor hadn’t had the time to explore. It said it in his notes and Stone vaguely remembered the words as he’d dictated them.
    “The ability to alter time . . .”
    He would get Dr. Robotnik back."

    Heartbroken over the loss of Dr. Robotnik, Agent Stone sets out to do whatever it takes to get the man back.

    Summary

    Something that was well-known amongst those whom it concerned was that Robotnik hated parties. And that meant that if someone were to drag the doctor to said party, it would be an absolute disaster. So thankfully, after quite a few times of Walters having been witness to quite a few spectacles and subsequently not wanting to deal with the massive tantrum, they never invited him. 

    That was, of course, except for the ones they couldn’t avoid.

    Summary

    "Left myself open," Robotnik hissed; or at least, he tried to. But he couldn’t actually hear his own voice to confirm he’d managed it, because there was nothing to conduct the sound waves. No sensory indicators of any kind. No feedback from his body. No one to hear him complain. Because nothing else was here.

    Because apparently that’s what happens when whatever the old man had powered the station with blows up.

    It sends anything in the epicenter to nowhere.

    But it doesn’t kill them.

    Exquisite torture. Robotnik had to hand it to the nature of the universe on that one. And it wasn’t even trying.

    Summary

    “Hello, I’m calling from Death-Cast. I’m Carla, are you Aban Stone?” Stone’s heart sinks slightly hearing his name, all of the last bits of hope that maybe, just maybe, they accidentally called the wrong person. But Death-Cast was never wrong.

    Summary

    "Sage… The doctor hardly gave his creations such affectionate names. Everything about this discovery was causing more and more confusion for the agent. What was the purpose of this program… "

    After the dramatic and deadly events regarding the Eclipse cannon, Agent Stone and the eggcentric Dr Robotnik retreat to one of Robotnik's last remaining 'secret' Labs in the Midwest of the United States. There, they must conform to domesticity, as many things said go unaddressed, but Stone discovers there is much more the Doctor isn't telling him when he runs into a program by the name of "Sage". Confused as to what her purpose is, Stone attempts to befriend the program, and Sage begins to express confusion and uncertainty as to why the doctor made her. Stone must force this answer from the doctor, leading to things unsaid finally being revealed.

    Will Robotnik's long-held desire to have a family finally come to fruition, or will it be shattered, just as his old Grandfathers had? Are the Robotniks truly destined to be alone?

    Summary

    Doctor Robotnik knows Agent Stone would go along with just about anything he wanted, no questions asked. So when bored with another bland G.U.N. assigned project, the sadistic Doctor decides to run a little side experiment of his own. His personal agent has always been obedient, time to train in a mark and reward.

    With escalating assassin attempts ramping up, G.U.N higher-ups wonder if the one guard dog is enough to protect one of their most invaluable human weapons.

    Summary

    Robotnik knew next to nothing about Stone’s wings.

    For the past six years, Stone had worn a wing cover every time he was around Robotnik. On or off the clock, his wings were wrapped, tightly clinging to his back - bound together by velcro and fabric.

    Stone keeps his wings covered, and it drives Robotnik insane.

    All it takes is a midnight work session and an intruder to fix that first thing.
