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!"

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.
