Summary
"What is it?" you asked, moving to his side by the console.
The radar display showed a single, insistent red blip against the sweeping green arc.
"It's a goddamn ghost story," Gunther muttered around his cigar.
Or:
A crossover between In Space With Markiplier’s warp-core chaos and Mouthwashing’s horrors. The Invincible II finds a long-lost ship adrift—but some missing things should stay forgotten. -

"Mark."
He lifted the hand full of peanuts.
"Mark."
"Give me a reason."
"Mark! No, no, Mark!"The Captain tried pushing away, only succeeding in tangling themself in the blanket they hadn't realized curled around their body. "Mark! They're gonna get everywhere- Mark!"
"Doesn't seem like my problem."
"Mark!"
Mark's hand went into motion.

They Shoot You Someplace While We Ache To Come Home Somehow by Far_Writer6952

Summary
Not a voice, not a person, not any tangible thing tells him, but he knows that the Captain is coming.
And he has a plan.
He won’t be alone anymore.
The universe glitches and he sees them, looking confused in their bulky suit and that god forsaken helmet; once, a symbol of hope for him. Now, he wanted to smash the glass in.
He raises the fire extinguisher in his hands and sneaks up beside them, raises it to swing, steels himself for the satisfying ‘thunk’ he would feel when it made contact. “Hi, Captain.”
And he swung.

Summary
If he were somehow more dead on his feet, he wouldn’t have heard the scratchy meows. If he hadn’t felt little claws on his foot, piercing through the socks he wore with the sandals hastily put on, he would have ignored the sound.
But he looked down to see a kitten.
Why was there a kitten just… out?

Summary
Eclipse (me, the author) is just your.. Well, not exactly average per say, high schooler.
One thing about them is that they are a big fan of Markiplier, and they especially love In Space With Markiplier...
Maybe that's where it went wrong.
They loved iswm a bit too much..
And when I say a bit too much, I mean that they have gone through every. Single. Route...
They've made so many people suffer while thinking it was just a simple show.
Now what will happen when they are the captain...?
I mean, what could go wrong...?
...
A lot, actually... -

Time And Time Again I Went Away, But Then Would Come The Time When I Would Need You by Far_Writer6952

Summary
Nightmares woke you again for the fourth night in a row. Usually, you were able to calm yourself down, curl up in bed and repeat the same mantra to yourself as you tap your fingertips together and count.
But tonight was different. You saw Mark die, you saw him be torn apart by a black hole, shot by some Lady, sent out of the bay window and hurtled in the vacuum of space.
You saw multiples of him, all different and chaotic and mind boggling, claiming to know you and you’d think you’d know them. For a moment, you’d swear you remembered this life, but no.
No, they weren’t him. They weren’t your Mark. They looked like him, but they weren’t.

Summary
“My name is Actor Mark actually, but I prefer Actor. This “Dark” you speak of isn’t here.... Yet,” Actor added quickly to end, a smile appearing on his face. Though, for a second, Yancy saw it twitch at calling him Dark. Must have been his eyes playing tricks on him; This man seemed nice, but something was off, much like the manor, so Yancy had to be careful. “Anyway, enough about me and.... Dark, you must be Yancy, correct? I’ve heard so much about you.”
The prisoner nodded despite Actor seeming off. “Yes, I am, but if youses could, can youse answer my questions? This place doesn’t look like the pictures Dark se-” He started but stopped when he noticed something behind the red-themed ego. Yancy quickly noticed that the manor had changed. The windows were fixed, the walls had no plants of any sort, the grass mowed evenly, and the door was fixed; All too much like the pictures unlike how it was seconds ago.
__
Or: Dark has been gathering egos at their manor, and Actor is sick of it. Why can’t he collect his own?

Summary
Six regulars and dozens of other patrons were going to be tough to handle, but then you just had to get involved in their lives and wind up the unwilling babysitter of a bunch of surprisingly infuriating products of an inter-dimensional accident. Why bother shutting off the water when the cup was overflowing? It's not like you were overworking yourself, anyhow. Oh, wait.

Summary
Mack from ISWM is stuck in a time loop, and I force him to repeat the 30 some-odd seconds of glitching after you say Mark's name in 'You're Not Mark!' over and over. Except! I also make it hurt like a bitch.
:)
-----------------------------------------
What have they done?
Why can he feel himself being torn apart? Atom by atom, everything seems to be collapsing… He suppresses a scream as he feels himself being torn to another place, bracing against the wall.
The world is tearing, just at the mention of one name. It’s not his name.
Why did they say his name?
“You do not get to choose whether or not I exist!” He can feel himself splitting open, like a thousand little needles ripping at the seams of his very being. “This is my shi-!”

Summary
Set a year after the Invincible successfully made it through their trip, the Captain and their crew have been doing well in setting up a new colony for themselves, but there's still plenty of work to do. Maybe even more so then expected, since during a (what was supposed to be) short supplies run, they suddenly get alerted of a distress signal from a freighter ship called "Tulpar". They decide to investigate, always willing to help those in need, but...why does this feel a little wrong, Captain?
...
Basically, this whole fic is an ISWM × Mouthwashing crossover where the Invincible Crew finds the Tulpar Crew, and, well, let's just say things happen :] -

Summary
You blink, your breath leaving you in a shudder as you lift your head to look up at the familiar and concerned face.
Another nightmare, another uninterrupted sleep and the mindless panic that would have sent you right off the bed if it weren’t for him.
Him, who’s now gently wiping at the stray tears and asking if you’re okay.
