Plot-Based AUs are AUs with a different or new plot from that of Undertale's -- for instance, a plot based on the backstory of each character or a plot which results in monsters acting/appearing differently from canon. Sequels and prequels to Undertale are categorized as plot-based AUs.

AUs with character role changes are Role-Swap AUs, and not Plot-Based AUs. They can have changed character roles to reflect a certain plot, but are not strictly considered plot-based.
