In a small town that doesn't usually deal with much trouble comes day that changes the lives of many. A beloved sheriff is struck down by one of the many well known outlaws and it brings shock to everyone who is on the scene. Now the outlaw is on the run more than ever before. He later on meets a so called legend of an outlaw who was thought to be just a myth. He begs to learn the old outlaws ways so he can keep himself hidden and alive. What happens to him is all part of the wild west. (The Gaster Gang and Swapfell belongs to Bunnymuse. Maestro belongs to flotts) (The cover picture does not belong to me)

No, it's not a sexual relationship between the two. _______ 1/21/20 _______ Fell being the big brother, and SwapFell the little. They both struggle to take care of each other due to the fact that their relationship isn't a loving bond between them. But they still show affection by keeping up with each other. Fell struggles with PTSD, SwapFell struggles with schizophrenia, which makes it harder on Fell. One day, he didn't see his little brother the next morning. It was cold, and the two had a small fight. That's when SwapFell left the house and didn't come back for hours.

The Gasters have lived in the void for too long, they come up with a spell they believe will send them all back to their homes, or at least a universe less.....empty perhaps even just one of their own. Something goes wrong and they end up in a strange universe where everything huge! Where they encounter a human named Y/n, But Is this a step up from where they used to be? How will they survive in a world where even the smallest creatures could be a threat........ (I do not own any of these characters this is strictly a FAN FICTION and all credit for the different Gasters, AUs, and art go to their respective creators) ENJOY!!!! (Also may include swearing so if you don't like that...ya know...sorry?")

Meet the Gaster family. Not exactly a family, but close enough. UnderSwap Gaster is the happiest and most energetic of them all. UnderFell Gaster is cold on the outside, but warm on the inside. OuterTale and UnderTale Gaster work together to find a way out of the 'positive' void they live in. Then, there is NewTale Gaster. The others call him 'B' short to Blindy or Blind, since he looks that way. B has to have the most tragic story out of them all.. And maybe one day they will see their normal AUs again, but not until they figure out how to escape and stay alive. All Undertale Characters belong to Toby Fox. Undertale AUs go to their respective creators. I own the storyline and a character or two only.
