Reversed Multiverse (Updates every week!) by Werecat1234
Fandoms: Undertale (Video Game)

Summary
After the events of Multiverse Madness, with Shattered and Reality now back in their own multiverse, the fighting is quick to once again break out. Reality explores and learns about his multiverse and the damage Shattered has done to it and attempts to save it, while Shattered continues his efforts to stop Reality and get him encased in stone again. The two of them make allies and enemies, Reality making friends and becoming part of a found family while Shattered follows in Nightmare's footsteps and manipulates his allies into thinking he cares for them. Traumas are experienced, friendships are strained, loyalties are tested, and deaths are witnessed and grieved for. It's an emotional rollercoaster, so be prepared for what happens, as it's not for the faint of heart.

Imagine It, If You Will... (Updates Every Two Weeks!) by Werecat1234

Summary
What would happen if Butters had tried something in Imaginationland? What if he had tried creating Professor Chaos to help against the evil imagined beings, and what if something had gone wrong? What if he'd accidentally given himself superpowers, and used them to finally become the greatest villain of all time?
Imagine it, if you will... what events could this small change trigger in the timeline, and how much chaos could it cause?...
Also, thank you to my beta readers Ali, Rain, and Nova! I appreciate you guys a lot and thanks for beta reading this fic with my UTAU ones! ^^
In Butters's POV except for every 5 chapters, which is in Kenny's POV.

Summary
Long ago, a multiversal rift was created. One that could end the balance of the multiverse forever should it break or get into the wrong hands. Bill, after escaping the Theraprism through a portal created by this rift cracking and managing to possess a Sans, began to search for it in an effort to create chaos and destruction. However, he was unable to do this alone, and enlisted the help of Nightmare, the two of them making an alliance. Bill helped Nightmare create his team through manipulation and some brainwashing, but they aren't the only ones gaining allies...

Summary
A collection of connected and unconnected one-shots (Even the unconnected ones will reference others), requested in the Discord Server and prompts that I wanted to explore further. One-shots will be of both Merging Timelines and Multiverse Madness, and each chapter title will show which story it's from! There may also be AUs of Merging Timelines and Multiverse Madness in here, and those will not be Canon to either story line. Also, not keeping the fonts for the MT boys, so them being missing isn't a mistake or anything in case you're wondering.
Note: The one-shots have random lengths. Some will be as long as a chapter, and some will be shorter. There will also be multiple parts to some one-shots too, depending on the plot.

Summary
When Sans first found himself in this void, he didn't think he would befriend another, less edgy, version of himself. Time passes though, and things change, and so do people, especially when they're stuck in an awful situation. It's nice having a friend to help you out and be there to talk to you, though.
Also thanks Rain for the title idea! ^^
Might add more to this if motivation strikes or if someone asks me to expand on this a bit.

In a confrontation in space, Sonic ends up falling into a trap by Eggman that allows him to use the power of the chaos emeralds to break open the earth and begin the awakening of a beast known as Dark Gaia. Now Sonic and his friends must go on a journey around the world to put the planet back together and stop the beast from fully awakening.
However, Sonic must also deal with a part of the beast that had found its way within him, causing a transformation when the sun goes down, and the entity within is not happy that Sonic is still in control when that happens.

Summary
One year after the Clean Sweepstakes culminated in the destruction of Restoration HQ, Sonic is called upon to help stop an Eggman assault on Westopolis, the city his self proclaimed arch rivals, Surge the Tenrec and Kit the Fennec, have claimed as theirs to protect. When an attack intended for Surge hits Sonic instead, he finds himself a potential danger to himself and others, and must rely on the last person he'd ever expect to be in his corner if he wants to remain free.
Sure, she says she's only helping because the Restoration agreed to pay her, but it's the thought that counts. Right?
