Your Secret Anomaly by New Old Moon reviews
Sans tries to use a new strategy to save his world from the being that is trying to wipe out all of monsterkind. This backfires tremendously when a human from the real world (that doesn't even know about Undertale) gets transported into his universe. Will this result in friendship, a game of cat and mouse…or the absolute?

One Simple World by Halloween Witch reviews
The butterfly effect is known as "a property of chaotic systems by which small changes in initial conditions can lead to large-scale and unpredictable variation in the future state of the system." The smallest of changes make the largest of impacts. So… What if when Angel and Frisk fell… they fell into different locations? Squeal "One World, Two Souls", and "One World, Many Souls".

For Monsterkind, the Surface represented freedom. For Frisk, it's a return to some uncomfortable realities. It all began with a simple wish. When that wish faded, Frisk tried to move on.
