Corrupted Timelines (list) are a type of temporal anomalies.
Description[]
Corrupted Timelines occur when an individual carelessly travels in time, altering the past by their sheer presence. Unlike "normal" alterations to the timeline, the changes in a corrupted timeline are chaotic and unpredictable, and may not causally follow the time-traveler's actions all that directly. By their nature, corrupted timelines are unstable and illogical, and it is relatively easy to unmake them by canceling out the change that sparked them in the first place.
Behind the scenes[]
Corrupted Timelines appear in various time-travel stories, such as Outta Time (2019).
