Needs a Better Title
- Suggestions: "Time Travel Duplicate Exclusion Principle"
A character travels back in time
and changes the past for good
, and then explicitly dies as an indirect
result, rather than vanishing as part of a Delayed Ripple Effect
or sticking around.
The reasons for doing it this way might vary. One reason might simply be to have a Time Travel
plot involving a visitor from a Bad Future
and/or a Heroic Sacrifice
but without changing the status quo
, either by killing a major character or harming their Uniqueness Value
; another reason might be to provide all the drama of killing a major character
without harming someone with Contractural Immortality
(see Expendable Clone
). Having multiple copies of a main character might just be confusing, too, so this also deals with that possibility.
For a trope which doesn't necessarily involve Time Travel
but still treats multiple copies of a character as expendable, see All the Myriad Ways
. Not to be confused with Clock Roaches
and Time Police
, which don't count because if they kill you, it is for all practical purposes a direct
result of changing the past. If a character dies attempting
to change the past, but merely causes a Stable Time Loop
, that's You Already Changed The Past
As with all Death Tropes
, these examples will most likely contain spoilers.
- Homestuck is noteworthy because there is a force actively working to make this hapen: if you're not from the Alpha Timeline, you're doomed, as is the timeline you came from. For instance, in a Bad Future, Dave went back in time, became "Davesprite," and then fell in a fight with Jack Noir when he went One-Winged Angel (although Davesprite was recently revealed to be Not Quite Dead, so perhaps the technique isn't perfect); then there's the hundreds of Aradia-clones who contributed to the fight against the trolls' Final Boss, and were all killed. Stable Time Loops are perfectly fine, though, and seem to be the bulk of how this force gets things done.
- In the Futurama special Bender's Big Score, this is actually a rule. It's a well known fact in the universe that a time duplicate, as they're called, has to die because of the paradox their existence creates, and becomes a plot point in pretty much every character's subplot.
