Undertale Charakters by: Toby Fox

The barrier is finally broken, and at last all of monsterkind are free to walk on the surface. Again. Sans the Skeleton is skeptical. Why bother getting excited for something that's just going to reset? This is not the first time the barrier is broken, and probably not the last. He feels the need to take a break for everyone else's enthusiasm and wanders to the ruins where he encounters a ghost of his past. The result of that meeting is something he has been hiding for a long time and that he's determined to keep hidden.

Just gasters

2 AUs with 1 goal is to get out of the Underground punishment. Not everyone's a Hero but not Everyone was a villain. 2 ends will meet to test the theory whether the Name means anything to them.

Logan and Patton were working on a project when something went wrong and a portal sent Patton into a different universe where he meets some new friends.

This is where his life begin in the void with the Gaster Gang. ((This idea didn't originally belong to me.))

Just some random gaster gang stories I thought of. These have been inspired by Bunnymuse and Flotts, so if you notice some of their pictures have been worked into these stories. If you notice what pictures I'm using, then good for you. If you don't, then get on deviantart.

The story officially begins when Toriel dies in her universe mysteriously. Gaster with his allies show up and take her soul remains back to his lab to save her life. Toriel then had DETERMINATION injected into her. Most of the DETERMINATION was collected from humans in multiple different universes. Gaster created the perfect solution to end RESETs and genocide routes that plague The Multiverse. A new kind of boss monster with the ability to utilize the power of the savestar. Toriel, who got reborn as Gaster's daughter in his lab due to a serious situation that happened, it was the only way to save her life. Gaster embarks on his quest to bring peace to The Multiverse. However The Savestar becomes corrupt, doing more than its intended function. If the RESET function is over-worked, it will erase a universe. The more universes that are gone, the more The Multiverse dies. They explore every universe they're able to, attempting to fix the savestar and rid the ability to RESET, helping others and themselves. ---- Note: This AU has themes such as Suicide, frequent swearing, mentions of needles and more medical equipment.
