Story: Gaster and Sans' relations in this AU is that Sans and Alphys were Gaster's assistants. After 100 genocide routes, Sans went to the Waterfall Door, due to Chara secretly giving him a vision of an old friend being there. He was unsure of Chara's motives, but sure enough, found Gaster there, or rather, the main piece of him, Mystery Man. He helped Mystery Man fuse with his other pieces, the Gaster Followers, allowing Gaster to shapeshift. He took the form of Sans, and fights you at the Judgement Hall to allow Sans to train. Chara was able to distract Asgore long enough (by being a ghost) so Sans could steal the six souls as well. ------------CREDITS-------------- ---Text engine--- @Glitch_Brandon ---Ideas--- @jaidenrealalt ---fog/clouds/smoke--- @jaidenrealalt ---sans code--- @Multiverse-modes ---bone engine--- ??? ---sprites--- xX_Spanish Monster_Xx on gamejolt The rest is by @C_A_T_D_E_C_K Remix by [ Your user ] ------------NOTES------------ If this engine is used, credit me and all the other people if you remix without anything changed, I will get it taken down
