Undertale Alternate Multiverse Wiki

An Alternate Multiverse (AM) is a multiverse separate from others. The Underverse (Undertale) is the main one. Every AM has its own Ink!, Error!, and Purgatory! Sans counterpart. Every AM contains an infinite amount of AUs. Some other examples are Swapverse (Underswap), Shiftverse (Storyshift), Fellverse (Underfell), Freshverse (Underfresh), Spongeverse (Spongetale) etc. Some AMs intersect with each other through certain AUs. For instance, Swapfell is canon both to the Fellverse and Swapverse. Examples of Inks for these are Ink! Papyrus (Inkswap), Ink! Chara (Inkshift), Inkedge Sans (Inkfell), and Ink! Patrick (SpongeInk).
