History Main / PeggySue

** Alpha Cody treats this pretty seriously since he used [[FallenHero to be a hero]]. Alpha Guy, however, [[LampshadeHanging lampshades]] and [[ShaggyDogStory mocks his trip down memory lane]]. [[spoiler:It's his new shoes!]]

While this might seem as a recipe for an overly powerful character, the Peggy Sue is not without its risks. Often the only way they made it through the first time was because of fate or luck giving them PlotArmor, a luxury that they will be unlikely to have a second time around, though they can try for TrickedOutTime. They may also have to deal with a weaker and less experienced body, mental baggage, gaps in their knowledge regarding past events, negative reactions by anyone who realizes that they know things they shouldn't, or worst of all, that another, less friendly, individual has also pulled the same stunt. Of course, the primary problem with such a scenario: as the character changes things, [[ForWantOfANail the new timeline becomes more and more different from the one they left behind]]... and thus they are less and less able to predict what's going to happen next. [[InSpiteOfANail Unless it doesn't.]]

* ''Manga/EdensZero'': A variation occurs for its final arc. [[spoiler:The crew of the ''Edens Zero'' use Etherion to travel into [[MergedReality Universe Zero]] for a chance to prevent [[TheMaker Mother]]'s death and the subsequent extinction of humankind, which also triggers a CosmicRetcon that forces them to relive their lives without their memories. Once they reach the events of Chapter 1, each crew member starts to [[RegainedMemoriesSequence gain the memories of their future selves]], while also retaining their memories and experiences of the new lives they've lived in Universe Zero. This allows them to take care of major events and loose ends earlier than they could have before, though they notice multiple alterations and discrepancies between universes, which keeps it from being a complete retread.]]
