Time Paradox Part 5 is a fan-made track by Doopix inspired by Undertale, the indie role-playing game centred on the skeleton character Sans. It is part of a series of similarly titled fan tracks shared online, where listeners associate its tense, cinematic style with dramatic Sans edits and alternate-timeline stories. Because it is short and builds to a clear climax, creators have reused it on soundboards and in short videos as ready-made tension music. Its continued use comes less from one viral moment than from its fit for boss-fight and time-loop edits.
