Kai Smith. In the Underground. Surrounded by monsters unlike anything he's ever seen before. All sorts of shenanigans ensue. This should be pretty self-explanatory, let's be real here.

Every universe... must have something called a timeline. One universe can have many timelines and are varied; there are also universe that have not many timelines, even none at all. And this time, we will see an example of one unique timeline from the universe called "Bluey's Blues".

Will the two girls know what to do when the time comes?

Frisk succeeded in freeing the Underground from the Barrier, and all is freed back to Tamriel... too much they see is wrecked with strife from the Thalmor, and now a Dragon Menace.

A simple question arose one day. What happens if some fandoms and their events take place in the same universe, on the same planet and in the same world, while somehow intersecting with each other? Now with this answer I want to share with you. It all started with a kind fairy tale, telling about friendship and kindness, and a family where there is a child who owns a power...

The Underground had seen an incalculable number of resets. Frisk, Sans and Flowey are tired of each reset, but in one reset, two new people fall into the Underground. Will these two break the cycle or will they become a part of it? Spoilers for Undertale and Fnaf Security Breach

Finding himself in a new body after committing suicide, Akaza sees the struggle of survival through the memories of his new body. He never thought he could redeem himself, but the opportunity seemed to be a gift from the very gods that had forsaken him long ago.

Anyone who likes this story will be added to the story and promptly killed, because you are wrong. also bqq is spelled wrong intentionally.
