Summary
It has been 1 year since Clover's sacrifice for Monsterkind, and all of their friends still have not fully come to terms with it, but among all of them, Martlet has taken it by far the worst. Only too late did she realize just how much the human truly meant to her. Love and grief can make you do many things you might regret, something Martlet repeatedly learns the hard way, but after the barrier is broken, a miracle of HOPES and DREAMS comes to pass that means perhaps she can find a second chance to rectify her greatest mistake and build a happy life despite what certain figures in the shadows may be plotting

Summary
In a moment of pure chance, two years after the barrier fell and he blinked back into existence, Gaster met a Mage as old as he is...and honestly, wasn't sure what to do with himself. He doesn't do much better at your subsequent run-ins either.
But stars, he just can't stop thinking about you. About what you are, what you can do...the world you both remember.

The way they excitedly swish around the room reminds him of their adventures in the Wild East.

It’s like he could eat them alive, their joy and beauty overwhelming.

Flowey and Clover go to an aquarium and he has to deal with the weird gay feelings he feels towards them

Summary
There have been a lot of rumors floating around recently. The barrier shattered, "fallen down" family members returning, true hope for the future of monsterkind... things like that. Things much too good to be true.
Everyone around Ceroba believes it all without question, and eventually she's pushed to investigate. But maybe those rumors aren't as false as she initially believed. Maybe she was a bit too quick to judge.
And maybe she can see the Surface. Maybe she can see her little girl again.

Summary
Frisk was overjoyed as they had finally found their true ending. Though, there were a few minor changes to what one might expect. Frisk had developed a deep bond with Toriel and Asgore, even more so than with the other monsters. However, their heart truly belonged to Sans and Papyrus. The conflicting personalities of the brothers had always charmed Frisk, the constant equilibrium of dry puns and enthusiastic banter resonated with them. At first, Sans was unsure if he was ready to take on the role of a parent, but with the encouragement and reassurance of both Papyrus and Toriel, he ultimately decided to give it a try. Toriel, in particular, noted that Frisk had made it through the underground thanks to Sans's protection and even offered to "babysit" Frisk whenever he felt overwhelmed.
But as with all stories, happiness is fleeting, and conflict between monsters and humanity continued to rage on. Politics and oppression reared their ugly heads, and Frisk's unknown illness added to the inner turmoil they were facing. Will Frisk be able to rise to the challenge?

Summary
"Bronx?" he scoffed, a question, still kneeling. “Sweetheart, you fuckin’ insult me. Mistakin’ me for that little shithead.”
Gun still firmly at the center of his spine, he sighed and huffed and pushed himself up. He was broader than you originally thought: much, much broader, easily dwarfing you as he rose to his full height. He was at least a head taller, twice as wide, his heavy-set bones covered by a black, fur-lined hoodie over a dark crimson tank-top. The dismal light showed the various scratches along his marrow. He smiled: one sharp canine was glittering gold, the same color as the thin chain that scraped against his exposed collar bones.
You didn’t back down. For a second, neither of you moved: your gun trained at where you guessed his soul would be, his eyelights assessing you.

Summary
Teleporting outside of the throne room, he could hear a child crying. Sans didn’t even notice the barrier was gone after a couple of seconds of staring at the scene splayed in front of him. Frisk turned around sharply, revealing the broken green Soul shards in their hand. Sans froze as his eyelights extinguished. This was the first timeline Frisk had ever seen the skeleton’s tears.

Summary
Monsters have been on the surface for over two years, flooding the already volatile streets of Ebott City with more crime and tension than ever thanks to the two syndicate factions that formed in wake of the barrier's fall. One is headed by Toriel Dreemurr - former queen of monsters with an openness for working with the existing dons and crime kingpins to further her own agenda. The other led by Asgore Dreemurr - king of all monsters with a thinly veiled disgust at trading one murderous prison for another for his people, his own goals just as suspicious as his ex-wife's.
Red is just trying to get by in a society run by humans he can barely tolerate where the only thing either side seems to have in common is the presence of secondary genders and a cautious distrust of each other. Meeting a prostitute in a bar won't do much to change his mind. Even if their first meeting involved a shoot-out in an alley and keeping her from becoming Alphys's new best friend.
Her being his boss's favorite side-piece? The beginning of a really big fuckin' headache.
[ Set in Undertale's Mafiafell AU with expanded and non-traditional Omegaverse dynamics. Told in third person omniscient ]

Summary
Sans knew he would have to come to terms with it sooner or later. Frisk was 15 now so it only made sense that they would want to take their role as ambassador more seriously. Just because the threat of assassination attempts and kidnappings were there didn't dissuaded their determination any less, even if they did keep Sans up probably way too late with worry.
It took some convincing but eventually Tori agreed to let him train Frisk, you know just in case. And thankfully to prove his point this training session brought a lot of surprises, for all of them really.

Summary
Monsters are doing their best to adjust to life on the surface, but harassment and hatred aren't easy to overcome. But even if the world they came from was Kill or be Killed, the Monsters really don't want to continue that path. So instead, they try to handle it the way humans do.
In court.
