Summary
The details of the job are pretty vague, but in the end, Simon agrees. It's a chance. At freedom. Life. No matter how slim or ridiculous the thought is in a dying universe. He doesn't know what to expect, but he certainly isn't prepared to wake up months later on a small ship with a crew of people that leave him with more questions than answers.

Summary
Everything sounded distant, everything sounded like he was trapped in honey. Though, honey would be more enjoyable than this. Simon felt like a sick dog just waiting to die, but he wasn’t being told he was a good dog or even that he served his life well. All Simon could hear was the blood rushing in.
____simon, my simon, ily... uhhh this isnt as evil as the above summary seems. he gets saved and i totally forgot about the super cancer sooo yeahhh

Summary
In a universe where omegas are not only rare but extremely dangerous, Captain Ava prepares an expedition into the blood ocean of AT-5. Only, things are severely interrupted when her best welder goes into an extremely sudden and unexpected heat. Now, the expedition is on pause while she and her crew desperately try to figure out a way to stop Jack from maiming himself or someone else.
Too bad no one told the prison that, and a shuttle arrives with a convict who was supposed to be sent into the ocean.
Maybe two problems can resolve each other.

Simon the Butcher.
When you were boys, Simon used to chew on the collars of his shirt. He had nightmares about jellyfish. You step forward, unafraid. There has never been a day in which you fear him, and there will never come a day when you do.
If you must follow him into the depths of a blood ocean, so be it. You would follow him anywhere.

And I Only Sink Deeper, The Deeper I Think by JackalopeMunchies

Summary
The creature’s limbs unfurl in a slow, deliberate sweep, and then—horrifyingly gently—it draws the sub toward itself. Not by grabbing it, not by crushing it, but by bracing its claws against the hull and pulling the entire vessel into the cradle of its body like it’s trying to hold something fragile.
The metal groans. The cabin tilts. Simon’s stomach lurches.
And he panics all over again.“No—NO—stop! Don’t touch it, don’t touch me—let go!” His voice cracks into something thin and wild. He scrambles backward even though there’s nowhere left to go, pressing himself so hard into the bulkhead it feels like he’s trying to fuse with it. “Let go, let go, LET GO—”

Summary
Ava discovers a new kink that Simon has and decides to put it to the test.
"Ava couldn't remember exactly how she acted before the wormhole. She moved in front of Simon and saw his knees were ready to buckle. His cock was already half hard. Her posture straightened and she grimaced. Simon was slouched over in defeat. He kept his arm behind his back as if his wrist was tied, and his eyes betrayed a certain kind of fear known only to the ones she'd sent down in the ships."

Summary
In my previous fic, Engineer Mark was pulled into the portal created by the warp core. His landing destination was into the Iron Lung, with Simon. But what if the reverse happened? What if Simon was pulled into the portal? He had just been sent into the blood, just scanned through the manual. But he hasn't used the camera. No radiation poisoning. He was hurled through the blue portal, into the Invincible II.
