Redtale is an AU of the video game Undertale by Toby Fox which takes place in an alternate history timeline, specifically a timeline in which Undyne and Alphys found Soviet propaganda in the garbage river instead of Japanese anime. This led to a noticeable divergence in the timeline, wherein Asgore abdicated his throne after a successful worker’s revolt in the CORE and Hotland that nearly led to the destruction of New Home due to a meltdown within the Core’s reactor. Undyne then took over as the dictatrix of the underground with Alphys as her second in command, along with Sans joining her secret service and Papyrus becoming the commissar of the Greater Snowdin Municipality. The AU has a more militaristic and semi-grimdark vibe compared to Undertale’s original timeline, with the lore being focused around how the underground has changed since Undyne came into power and took steps to realize her authoritarian communist utopia, known as the Underground Socialist Union.
Within the Redtale AU, Muffet was strangled by the authoritarian economic policies of the Underground Socialist Union, leading to the formation of the spider mafia.
