Summary
Sans Undertale struggles to adapt and move on while integrating on the surface.
The troubles of his past haunt him, the burden of his old home, coming from a different world, being aware of resets, the trauma is all messing with his head.
He’s already fallen into depression and other darker thoughts.
Will he succumb into hopelessness, or will he realize that people care about him in time?
OR
What if Sans Undertale is actually from Deltarune? What will a man with such knowledge and burdens do? Will he stay determined? Or will he succumb into the despair that the universe threw one thing after another at him, as he tries to move on in a permanent happy ending.

Summary
The angel of the underground was left abandoned. They guided everyone to their happy ending, a perfect score. 10/10. No notes. But as soon as they turned to follow Toriel, they were kicked out. Sent to the Void. Even their vessel was discarded, just like they were. They get sent to a world quite like their own, but it's not the same. Not their own. Not quite.

Summary
“So I ask again, dear Phoenix. How bad does that scar burn?”
The long, eons long war between the angels and demons has ended decisively in the angels' favor, due to the newly appointed Angelic General, Frisk. Their strength and determination ensured a victory that was all too easy, wiping out every demon but one. One demon who was away, tricked into leaving while the angels attacked. One demon who would usually be ever too tired to think about taking revenge.
But there is only so long one can withstand the boredom of a lonesome eternity before the idea of revenge begins to sound fun.Or,
A demon Sans forces an Angel Frisk to fall. Long revenge monologue included.

OR
Papyrus realizes that being on the Surface hasn't helped his brother's crippling depression, because his HP is still 1. So he decides to bring the others in on his brother's stats to try to help.

Summary
A creative slump sends you searching for inspiration in the wilderness, but one misstep lands you under a mountain instead of on top of it. As you navigate a world filled with puzzles, quirky monsters, and an unsettling sense of déjà vu, a certain skeleton keeps popping up—startling you with his sharp wit and toothy grin. There’s something about him, though… something your heart can’t ignore, as if it was always meant to lead you here.

Summary
You freaks have played Undertale, right? Once the story's over, you ever wonder what becomes of that one creepy kid who ate all those buttercups? Well, wonder no more! Because my name is Chara Dreemurr, and I'm here to tell my story. A possible version of that story, anyway; one where I get sick of being dead and decide to get proactive about it. It may or may not end well.
Anyway, read the tags if you want an idea of what the hell's going on here, despair at the lack of shipping tags, gape in horror at the number of depressing tags that had to be added on my account, and strap yourselves in. I have a lot of personal issues to work through and I haven't had chocolate in about a hundred years, so this is probably going to get worse before it gets better. =)

Summary
This is not a tale of slaughter for the so-called "greater good".
This is a tale of one who has grown tired of such slaughter, bringing justice to so-called mistakes of the multiverse. A tale of a faceless killer... of "Dusttale's Endbringer".

Summary
Things had settled down after Twilight and her friends freed the ponies of Starlight's Village.
A.J. had made a killing on the farm, selling pie after pie. At this rate, she'd be able to buy Applebloom those Sapphire Shores concert tickets her and her friends had been begging for, and maybe even one for herself. Not that she was into pop, but why not? Rainbow was also beaming, having gotten into the Wonderbolt Reserves. Even without the full title, she was on cloud 9--quite literally. Maud and Pinkie had another trip planned together, so every pastry she sold was like another step closer to their trip date. Not only that, but Rarity was on top of the world herself; Sassy had recently informed her that the boutique had collected so much profit, they could renovate!
And of course, Twilight was engrossed in another new book series. Spike didn't mind it that much; it allowed him to indulge in ice cream without her knowledge.
But what about Fluttershy?
She'd say she'd been having a lovely time with Discord, except for the fact that Princess Celestia had personally arrived on her doorstep yesterday, revealing a new Friendship Mission that would put those she loved most in danger.
Easy, right?

Summary
It's been three moons since Night killed everyone in his village. Its been three agonizing, heartbreaking moons since he had killed his brother.
There's not much to do in a soulless world. This changes, ever so slightly when he hears a desperate call from someone in the abyss.
Night doesn’t know what to make of his new situation, and he can't bring himself to move on just yet from the horrors he's committed. But life demands his interaction and input, so he forces himself up anyways.
Dream would do the same, if they were here. But they're not, so Night might as well pick up the slack.
