Echotale is an old AU (alternate universe) of the indie RPG UnderTale, being created only around 2 years after the game's release.
The plot of the universe is mostly unchanged, but the character Sans is infused with the energy of the character known as Gaster, and obtains a very monochrome appearance, along with the colors of his eye changing to represent the in-game color of the Justice SOUL.
