The entirety of Ainz Ooal Gown, all 41 members, find themselves transported into a whole new world on the last day of Yggdrasil. How will a guild of 41 all-powerful heteromorphs change and influence the events that happened in canon, while also creating entirely new events to explore? For you, the dear reader, this is a tale best told as a theory, a theory on godhood.

A confused Overlord arrives in a New World lost and alone; see how he will deal with all kind of situations while becoming the obsession of a certain Witch Princess whose destiny will be changed forever by a chance encounter! (M because of Overlord stuff and a certain yandere. NO OC player)

The Sunlight scripture's desperate weapon was not an angel, it was a race change item. Ainz's humanity is restored... and that's a problem. The butterfly effect results in many changes. Some die who lived, some lived who die, but still the will of Nazarick in this retelling, will not be denied. His level cap shattered and his humanity intact, what happens? Read on and see.

There was only so much bad luck to go around, I thought. I was wrong. The world could not have been more deliberate in its attempt to spite me. It plunged me into the deepest depths of hell it could. A bullshit crazy world with bullshit OP characters. Me? I'm Climb. A human. A human who loves to metagame. [Reincarnated!OC, Canon Divergence]

For years the Doom Slayer has remained dormant in silent suffering. His tomb is found by a group of scholars with a young scribe who unlocks the way to awaken the Hellwalker in this New World. For better or for worse.

Demon Lords? Heroes? The dream of every isekai wannabe ever. But it seemed God had a funny plan in mind with me, because I'm stuck in a cave as a flipping Basilisk! So, what? I can get out of this! It's not the worst start I could have if we're being honest. Just have to survive however I can to make my way out of here. So hey, I can make this work. Probably. Maybe. Hopefully.

To regain a fraction of his humanity, Ainz attempts to create a spell capable of countering his emotion suppressor: but the incantation is more potent than expected, and Suzuki Satoru finds himself irreversibly restored, in the flesh! As more and more people find out and misinterpret the transformation's purpose, will Ainz be able to uphold his façade as the incorrigible Overlord?

Wounded, lost, but growing, the lone wolf awakens in a land not his own of which more colorful and vibrant life thrives, but also young and weak. Similar to home, but so different, Garou must wander the lands and find his purpose in a world where heroes were frail and weak, where the pain of the powerless was ignored by the many. And he will change that world with wrath and fury.

Momonga, before Yggdrasil shut down, decided to go ahead and mess around a little and created a level one human character. Now, he finds himself in the New World with practically nothing to his name, and only a very horny succubus as an ally. Suzuki Satoru x Albedo.

The IMD operates in the shadows of countless worlds, masquerading as higher beings to influence the course of history to their desires. One of their most trusted "On Field Supervisors" gets transported to the New World to serve as a "guide" to Albedo. To what extent will the presence of a sharp-tongued but short-fused entity affect the events that follow?

Momonga was unwilling to let the Great Tomb of Nazarick to pass without one last time within the game he so loved. He is joined by the oldest member of the guild that everyone affectionately referred to as Gramps in its final moments. How will the Lord of Death and the Lord of Illusions fare in this new world they find themselves in?

What if Ainz's guildmates eventually did come to the new world? How would they react to there new forms, as well as the world that Ainz has decided to create?

Saitama is the world's strongest being, able to defeat any and all threats, no matter how powerful. But what happens when he becomes the threat?

As Ainz organizes a massive event to attract attention to his newly reformed Adventurer's Guild, unseen powers begin to move as the Sorcerer Kingdom sets out to establish its dominion on the chessboard. A conspiracy unravels in the palm of Demiurge's invisible hand. Nabe and Evileye as roomies? Chuunibyou Lakyus? What could possibly go wrong? (Set in between volumes 13 and 14)

[AU][OC] When an Angel solo player is thrust into the New World before the rise of the young prince who would become the Bloody Emperor, how will the player decide to make his mark? Read on to find out. No Nazarick (maybe in sequel).

Chara woke up, not in their room, but on a bed of golden flowers down in the Pit. There's a human child sitting next to them, so this obviously could only mean one thing: Human invasion. So, they'll just murder the child, go home and make sure mum, dad, and Asriel are all okay. It's not like they woke up years in the future where they've been dead the whole time, right? [Charisk]

"Peroroncino and Momomga" fic but this is the Mature version. Very Lemon. But no story different from the T version whatsoever. F.Y.I. I will let you know which chapters have mature content at the beginning of each chapter. PLEASE! Don't take this story too seriously as it's just smutty writing! This is nothing more than stupid fun, stupid the main word here. AU and OCC warning.

Once upon a time, a mother had lost her son. He had disappeared without a trace. Several years later, her hike up the local mountain of her new hometown leads her on a journey that begins where his had ended. Hopefully, she will find her son and set him free. Hopefully... If she can set herself free as well...

The Genocide is over, Sans and Frisk have finally won; and they are all alone. But what if there was a way to bring everyone back? Rated M for mature because of language and violence. SansxFrisk. Ambiguous Frisk, no bonezone. Image belongs to rightful owner, UNDERTALE belongs to Toby Fox.

"This one is machine and nerve, and has its mind concluded. This one is strength and death, and cannot be eluded." There are those that are called Demons, and there are those that are called Slayers. And when the time comes that they are banded together, those that rise against them will fall just as quickly. Alternatively titled "Universal Doom: Chapter 20".

After a brush with near-death, Tatsumaki realizes she cannot be the pillar of hope the people need. For the first time in a long time, she is afraid. The only one who can save her from that fear doesn't understand the concept of responsibility. There's more to hero work than a good fight and more to bravery than strength alone. The world needs a true hero, but what does that mean?

Across the continent, nations are receiving an invitation to a summit hosted by the Sorcerer King, with some looking to this as a possibility for peace, others seem to think there is more to this summit than meets the eye, how will these nations react when faced with the existence that is Ainz Ooal Gown!

Trapped in never ending resets, unhealthy co-dependency and the knowledge that the only guy who remembers hates them, Frisk and Chara are out of options. So in the minds of traumatised kids, suicide is the last option left. But suicide is a pretty memorable thing and emotions may be stronger than memories. Especially to the person who finds their dead body. (M for violence.)

The Underground gets one Hell of a newcomer. Follow the Doom Slayer on his path to escape the Underground, meet new friends, and make pasta. Uses elements from both the 1993 Doomguy and the 2016 Doom Slayer. Rated T because, duh, Doomguy. Cover art by DiscoEndy9 on DeviantArt.

A fan's vision of volume 14. After safely conquering the Re-Estize kingdom, Ainz gets flustered by the prospect of heavy paperwork and accidentally announces an international tournament to be planned by him. How will Ainz handle this mistake. Read the rest to find out!

In the battle against Lord Boros, Saitama was sent to the moon. He tried to jump back to Earth, but he may have placed too much strength behind his legs as he sped past the speed of light breaking the law of physics, entering another dimension, and landed on another planet.

In their pursuit of knowledge and power, defectors from Zurrernorn try summoning something directly from the realm of the gods. However, what they pull from the other side is completely unexpected. Away from home and disoriented, a madman finds that when the world is filled impossibly powerful beings, science is his only ally.

Frisk woke up in their bed. Their old bed. Had their whole adventure been a dream? Perhaps. But does that really mean that none of it was real? The monsters they met along the way certainly don't seem to think so. (Original post-pacifist AU. Rated T to be on the safe side.)

To say Krillin was having a bad day would be an understatement. Heck his last 5 years hadn't been great, sure things had improved and just when he thought he would be able to grasp at being happy it seemed that this world's Kami would rather see him miserable. That is if Kami even existed in this world, for Krillin had tried looking but had come up short.

In the aftermath of the fighting in the Holy Kingdom, after Ainz makes his way back to Nazarick, the Slane Theocracy makes its move. Thus far, they have only seen the civilized side of Ainz Ooal Gown but now the gloves are off, and there will be no mercy for those who dare to challenge Nazarick and the Supreme Being. Fan Volume 14, but with a few minor tweaks to the end of 13.

She is broken, and they are to be the guide to help her back on her feet; but, when secrets spill open and voices start to whisper, would it really matter if they are full of warmth? Because, when all is said and done, a monster would always be a monster and a hand stained with blood cannot wash its sins easily. sansfrisk (trigger warnings for abuse, blood, self-harm, suicide)

Apart from Momonga there were many others who were in Yggdrasil on the last day. This is the story of such a character. On the last day of Yggdrasil one of the key members of the Angel-Type Guild Seraphim stays behind to clean up after an ingame party. She later finds herself caught up in the most bizarre situation.

I knew I was... different. Everyone knew it too, so we kept our distance, that is, until I met a certain man who drew me in like a moth would to light. OC

At the end of service, on the last day before the servers shut down, thirty seven members of the Guild Ainz Ooal Gown were retired. The other three paid one last visit to the Great Tomb of Nazarick before going their own way, leaving Momonga alone. But what if those three stuck around until the end?

A series of snippits based on the idea that Saitama was considered the number one most powerful villain and a God level threat for years by the entire world... and never knew.

Looking for closure after finishing the game you write a letter to the characters. You never expected a reply.

Title inspired by GaoGaiKingTheGreaVA! What happens when Saitama discovers an underground filled with monsters who have been trapped for many many many years? Honestly, only chaos can ensue. Chaos, destruction, and pure awesomeness. This is likely to be a garbage story, so i apologize in advance, but hopefully somebody out there enjoys it!

Frisk refused to die... but he died anyway.

Relatively short, happy chapters about life on the surface where Frisk, Toriel, Sans and Papyrus live together. Some hurt/comfort but nothing depressing, mainly happy monster family fluff. Romance is not the main focus, but there is Alphyne, eventual Soriel and Papyton bias. Alphys, Undyne, Asgore, Mettaton, Monster Kid, Asriel and Gaster (and more) also show up.

Frisk is a quiet child. They were a SOUL made of kindness and DETERMINATION. They withheld their tears and loved their enemy as a friend. However, they also kept a secret from those that had grown closest to them. A secret that could mean permanent death. No more RESETS. No more SAVES.

With only four senses, Touch, Taste, Smell, and Hearing, Frisk must make it out of the underground without the most crucial sense for her survival, Sight. Blind!Frisk AU.

A succubus lands in the underground. If she wants to get out, she's going to have to make a bad deal. ...and possibly break every rule she has.

Sans had a question to ask in the Judgment Hall. Can even the worst person change if they just try? But Frisk has a question too. "Do you think that even the best person can change into something bad if everything is against them?" Spoilers for both Pacifist and Genocide route, a rather brutal and accusatory drabble. Don't be afraid to leave reviews or rebuttals.

"If we're really friends, you won't come back." But Sans' memory throughout alternate timelines never holds, no matter how bad it gets... until a post-Genocidal Frisk returns to redeem herself. Telling him the truth sparks a series of events entirely different from her previous resets. (As fair warning, for the sake of simplicity and plot purposes, Frisk is female.)

After the events of "Tally Up Your Sins," you and Sans have to learn to live with your pasts and figure out how to move forward, all while unraveling a mystery that dates back to the first war between humans and monsters. (Part 2 of the "Still Counting" series) (Rated T for: body horror, graphic violence)

Frisk was living on the surface with their new family. Everything was perfect except, the dreams that seem to belong to someone else. Something is left undone. The past is pulling them back. The world is reset, everything is undone. Somehow, they have to break the cycle and save everyone, and themselves. (pacifist run spoilers)

Howdy. Yep, it's me. Flowey. Flowey the flower. This is the journal I'm supposed to write in now. Just know that I did NOT want to do this. This was Frisk's idea and Toriel endorsed it. Don't expect me to write in here every day. I'm just writing right now because I have nothing better to do. Post-Pacifist. Floweypot AU

When a human enters the underground, they are surrounded by centuries of trapped magic. Those with a strong will, with high levels of determination, may be blessed with a gift. The red soul, the soul of determination, may have saves and time, but another soul could rival that power, if only they would brave the cursed Mount Ebott.

Tired of watching Chara kill for sport, Sans creates an elaborate plan to evacuate the monsters with the most challenging game in Monster history: hide and seek.

(Requested by Anon) You look at these monsters, but all you see is a freakshow. And you're not afraid to speak your mind. Especially not to that little 'ambassador'.

With a little glitch, Frisk awakes as they fall rather than resetting amoung the flowers. This new turn of events leaves a very dead body at the bottom of a mountain. But with magic and determination, anything can happen.

Frisk falls down into the Ruins, but when they try to speak to Flowey, he doesn't understand them. Now he's on a journey through the Underground with this kid, and sometimes they get this weird gleam in their eyes and it looks like they're talking to themself. He doesn't have time for this when there's a couple of human souls that need to be stolen.

Don't cry. Don't cry. But the truth is, I want to say out loud, "Don't go." - A confession goes wrong, and Frisk wants to disappear. But she loved Sans, and she had promised; never again. So she finds another way to disappear, all alone. Warning:Self-Harm, Suicide. fem!Frisk "PLEASE.. DON'T . . I BELIEVE IN YOU. . ! !"

" every time i tracked him down, something killed him right before my eyes. i had failed him as a sister. every. single. time. do you know what it feels like to watch your little brother die, over and over and over, while you're helpless to stop it?" Sans felt his sins crawling up his back. One-shot.

Isolation. Anger. Depression. After that lady behind the door, the one he thought he could trust let that killer through, Sans is feeling a whole range of emotions. How could she have done this? Why wasn't she answering the special "knock knock" jokes he had prepared for her? Come on, lady, just answer the door. Please?

You've been stuck in a time loop for decades when you fall down a sink hole, expecting to die. Instead you meet a flower with a fake smile (you die a lot). On the bright side, you might actually discover what causes the loops - you just have to find a human named Chara. This can only go well. OC-insert

Years after playing Undertale, you've all but forgotten about the game. It was fun while it lasted, but once you'd exhausted all possible endings and dialog options, you became bored with it and moved on to new hobbies. Until one day, while camping with some friends, you find a hole in the ground. (Part 1 of the "Still Counting" series) (Rated T for: graphic violence)

Sans is tired of following the script. So he decided to mix it up a bit. Not that it matters, it will always end the same way. Inspired by Mideater's Last Lullaby.

Six Gods descended upon the world and brought salvation to humanity. Eight Greed Kings were set free to destroy everything those before them had built. Forty-One Supreme Beings would be called forth to surpass them all. Momonga's heartfelt wish is granted, but all things come at a price. AU.
