Summary
You died. Sans died. But in the void between life and death, you found each other, and a chance to live again.
Merged into one body with a dying child skeleton, you wake up in the middle of a brutal war between humans and monsters. With baby Papyrus to protect and your brother Gaster's experiments turning you into something more (and less) than human, survival means running, fighting, and holding onto whatever shreds of innocence you can preserve.Or: Isekai War AU where you get hit by Truck-kun, merge with Sans, become a child soldier, and eventually end up in a polyamorous found family with 14+ skeletons. Features: PTSD, creative use of green magic, so many puns, and the aggressive pursuit of a normal childhood for Papyrus.
no stripes or brother/brother are involved in romance.
Ask not for whom Truck-Kun honks, Truck-Kun honks for thee
This is entirely plotted out and outlined but will not have a set release schedule

Summary
The mating process unfolded in three distinct stages: Selection, Gift Giving, and Consummation.
Monsters mated for life, a commitment not to be taken lightly, and humans retained the fundamental right to refuse at any stage.
After the selection, when a Monster presented a gift, the human had exactly two weeks until the peak of mating season to accept or decline. Due to the immortal nature of Monsters, the minimum mating age for humans was set at twenty-five.
Beyond these basics, the intricacies of Monster courtship remained shrouded in mystery, even as they loomed large over human existence.
What follows are personal accounts from couples who consented to share their experiences for research purposes.basically a series of meetcute smutty oneshots with each skelebro

Summary
Ah yes. The classic ‘’Heather’ convinces the skeletons you’re an evil human so now it’s a EVIL reverse harem’. Right?
Oh? But what’s this? A TWIST?
Sans couldn’t live with himself after what happened to you, going near insane after you’re gone. So behind the others back he uses the machine to undo what he did, except it didn’t. He can still feel his sins crawling on his back.
Oh well, it’ll all be worth it once he has you back in his cold hands again. Screw the other skeletons.

Summary
Months after the Avengers' dispute in Germany, the team returns to the US and moves back into the tower. As always, everyone pretends that nothing happened. Tony is just fine with this. He's used to pretending, and he'll be damned if he lets any of them see him flinch.
Tony's the bad guy, after all. He's used to it. He's fine with it. He's good at it.
Only now, there's something far worse loitering around the tower - The Winter Soldier. No one notices the guy at first, but when they do, Tony figures that he should have the soldier's back.
Birds of a feather should flock together, and the bad guys should start a book club.
