    Summary

    Rodimus finds himself in the most ridiculous situation of his life, but he shouldn’t be surprised. Of course he’d end up falling for an alternate version of Megatron even if it was a monumentally bad idea.

    Cracking his optics open, Rodimus forgot every word he’d ever known. Because staring down at him, mouth drawn back in a familiar snarl, was none other than Megatron.

    Not his Megatron, obviously. But close enough to make his spark stutter in confusion. This version was younger, less worn down by time. Still, the crimson optics, the way his helmet curved, the massive fusion cannon humming inches from his face?

    Yeah, he was similar enough to his own Megatron that Rodimus knew he wouldn’t hesitate to pull the trigger.

    Summary

    Starscream wakes up on the battlefield as a sparkling with no memories of how he got there. It's not the Decepticons that take him home, though: it's the Autobots. The feared Deception Second is now a cute, precocious sparkling with no memory of the enemies he's now living with.

    (or, Optimus found a sparkling and adopted him instantly. It's hardly the first time.)

    Summary

    The Prime is an intermediary between the planet and its God, a great honor full of rituals and mystical secrecy. Too bad for the powers that be, the new Prime is gutter trash from no lineage of note. And he's about to meet his God for the first time...

    Rodimus has his flaws, but if you need a mech to make a brave and reckless stand, there's no one better.

    Summary

    A collection of AUs predicated on the thought that Megatron remembered Rung after all those years, after that brief of an encounter, because, well... that day in Maccadam's, Megatron might have fallen a little bit head over heels.

    This is a massive collection with many moving parts! If you only want to read the core plot of the timeline, no detours, no frills:
    “The Snap of the Spring” (sets up the rest of the timeline)
    “Overlooking the Lake”
    “To Be Securely Held”
    “Castle in the Sand”
    “A Serious Affection”
    “Apotheosis”
    “Operating Instructions”

    Summary

    Jazz narrowed his eyes at the mech. Something about him was almost familiar. He stared hard at him, wracking his processor. His frame was way too fancy to be a common mech, maybe he was on Council? But he kept tabs on all the Councilors and didn’t recognize him. Maybe a Tower mech, or a- Wait. His optics widened with shock and he took a startled step back as realization hit him like blaster fire.

    Jazz turned in his seat, cube at his lips, just in time to spot the white pursuit vehicle steaming and panting in the doorway. “Jazz of Staniz,” the enforcer shouted, “surrender the matrix and come quietly!”

    Jazz knocked back his drink. “Well!” he said to the open-mouthed bartender, “time to split!”

    Summary

    Thundercracker and Skywarp have always been inseparable—but some bonds are meant to remain unseen.

    When the two Seekers volunteer for a mission no other Decepticon wants—over a year stationed at a distant, isolated base to intercept Autobot transmissions—they return changed. Quieter. Sharper. Heavier, as if something followed them home.

    Skywarp is no longer the playful shadow haunting Thundercracker’s wings. Thundercracker watches everything, trusts no one. And neither of them will speak of what truly happened during that long absence.

    Rumors begin to spread through the Decepticon base. Whispers of cries echoing through empty corridors in the middle of the night. Sounds that shouldn’t exist. Something small. Something alive.

    Megatron must never know. No one can know.

    Because some secrets are worth starting a war over—and some are worth destroying the world to protect.
