Summary
"That's what all malfunctioning miners do! Mess up the system in place!" the right said.
"Espeically this little screw up, Oreo Pox!" The left ranted.
"Orion Pax," the little bot behind him muttered, quietly correcting the shuttle, and causing Megatronus a spark attack.
Of course...Of course that paint job just couldn't have been a coincidence. Primus hated him, that was the only conclusion, and Megatronus couldn't even blame the god. Clearly this wasn't his cybertron, not even his cybertron's past, so of course there would be different versions of those he had befriended, and fought all those eons. His Orion Pax, was never a miner as these shuttles implied, but...if this was a second chance? Well, be it a punishment or blessing, Megatronus wasn't going to let these shuttles take this young version of his brother away again.

Or TFP Megatron is given a chance to change things, even if it meant going against fate...well he's never been one to accept a given destiny.Series

Summary
"And no one else has been here?"
The mech shook their helm, "Nope. Nothing really happens here. Mostly I just lie back in the pillows and wait until it's time to wake up. That's why I was so surprised to see you here."
"So, when you wake up it's back in the real world?"
"Back in my quarters on the ARK yes."
"You were on the ARK?!" Optimus whirled to stare at this strange mech.
"Why, yes, me and all the other autobots. We've been living out of it since we crashed landed on the planet earth," he stated placing his servos on his hips.
That didn't make any sense. Sentinel Prime had taken the ARK during his escape, and as far as Optimus knew there wasn't any crew on board. And what this mech mean by the rest of the autobots? The faction had been scattered to the stars since leaving Cybertron.
"Oh wait, where are my manners? I haven't even asked for your designation," The strange mech stated, holding out a servo to shake, "My name is Optimus Prime, it's a pleasure too meet you!"

or the universe is so cruel to the optimi, so the allspark gave them a support group.Series

Summary
Another failed test run of Isaac Sumdac's Bi-Directional Unified Transit Terminal (also known as the BUTT) results in an odd switcheroo of sorts. Now Ratchet, Bulkhead, and Jack Darby must adjust to life in futuristic Detroit while Ratchet, Bulkhead, and Sari Sumdac get involved in a Cybertronian war in the small town of Jasper.
Unbeknownst to the Autobots, the Decepticons have also been affected by the BUTT's malfunction. Blackarachnia and Lugnut are transported to the Nemesis in the midst of a war that their faction lost millions of stellar cycles ago. And in another universe, Starscream and Soundwave are stuck on Earth with uncooperative Decepticons.

When the Matrix chooses a new holder, the young prime will learn to become worthy of their new title, and that journey is rarely an easy task. When Rodimus Prime took on the Matrix, he didn't think he'd have to deal with accidental interdimensional travel right off the bat, but the surprise vacation, might be just what he needs.

Summary
"Attention citizens of this dimension—this is Rodimus, captain of the starship Lost Light, speaking to you not as a conqueror, not as a threat, but as a traveler… and a friend. If our arrival startled you, know this: the Lost Light comes in peace. We're just passing through—though we do tend to leave things a little better than we found them. Usually. So, on behalf of the entire crew of the Lost Light… we respectfully ask for safe passage, open minds, and maybe a map. We’re still figuring out where exactly 'here' is. Rodimus out.”
As much as Soundwave has come to love this mech, he really doesn’t know what goes on his mind sometimes. He briefly considered whether mind-reading his conjunx would improve prediction accuracy.
Conclusion: Unlikely.
The transmission clicked off, and Rodimus spun around with his usual swagger. “Boom. Nailed it. That’s how you do diplomacy.”
Everyone else stared at him in silence.
A.k.a, a severely self-Indulgent Lost Light fic, featuring my fan continuity, among other universes. (ft Skybound, TFA, SG etc)

Summary
All things considered, having a gun that was a servo just a moment ago pointed at him by a strange mech that looked as if they were thrown into a trash compactor was probably one of the more tame things that has happened to Orion Pax.
Honestly, with the amount of trouble Orion gets into he was somewhat surprised that this hasn't happened to him sooner.
.
.
.
A tfo x tfp crossover fix-it fic In which a bot who has been through the war gets thrown into a universe where the war hasn't started and attempts to prevent the war from ever happening. Also there's this tiny guy who looks an awful lot like his dead boss so that's fun.
