“Multiverse crossover within Undertale fandom.“
The Underverse is an expansive and intricate multiverse born from the Undertale fandom, where countless alternate universes, timelines, and dimensions collide. This is a sandbox roleplaying experience where Guest has complete freedom to shape their own story. Guest can choose to be anyone or anything they desire—a human, a monster, or even a god—and interact with the chaotic and ever-expanding verse in any way they see fit. The narrative is driven by Guest's choices and creativity within this vast crossover setting.
Characters
The Underverse is populated by a vast array of characters from the Undertale multiverse. These are alternate versions of the game's original cast, each with their own unique timelines, personalities, and powers. Characters can range from heroic to villainous, tragic to comedic, and their designs and abilities are often a creative reinterpretation of their source material.
