'''Basic Trope''': A character travels through time and causes an impossible event or paradox.
* '''Straight''': [[MyOwnGrandpa Alexia accidentally becomes her own grandmother.]]
* '''Exaggerated''': Alexia brings technology from the 2500's to Ancient Rome, accidentally becomes her own ancestor, and ends up leading to an endlessly long world empire.
* '''Downplayed''': Alexia uses time travel to detonate a grenade twice, first its future copy and then the original in the past.
* '''Justified''': The "paradox" cleans itself up. Once SanDimasTime reaches Alexia's birth, time rearranges itself so that she ''[[StableTimeLoop always]]'' caused those events.
* '''Inverted''': The universe would end because of a natural paradox in it (no meddling necessary), until Alexia sets the time stream right.
* '''Subverted''': Alexia accidentally kills her own grandmother, but when she comes back to the present her grandmother is alive ''and'' she herself isn't erased from existence.
* '''Double Subverted''': Turns out it's her grandmother's twin sister. [[PuffOfLogic Poof]] goes Alexia.
* '''Parodied''':
** Alexia causes a Pradadox, and everyone in the world only wears Prada.
** The world to turn into BizarroWorld through increasingly hodgepodge attempts to "fix" the last paradox she caused.
* '''Zig Zagged''': Alexia killed her grandmother, but what she doesn't know is she was supposed to die anyway, except that's because of a StableTimeLoop, only now she can't exist.
* '''Averted''':
** Alexia kills Hitler, uses a TimelineAlteringMacGuffin, and sets up an empire using 32nd century technology. The effect? She creates an alternate timeline because the changes were too radical. Her home Earth goes unchanged.
** Alternately, time has a cleanup crew (be it TimePolice, ClockRoaches, or the ButterflyOfDoom) that can fix any problem, so there aren't ever paradoxes.
** No TimeTravel.
** No one changes anything.
* '''Enforced''': "It's a story with TimeTravel, ''of course'' there has to be a paradox!"
* '''Lampshaded''': "Great. Just ''great!'' We've killed ourselves from five minutes from now. Now we have to take their[=/=]our place and get slaughtered by our future/present selves or destroy the universe!"
* '''Invoked''': Alexia convinces the MadScientist not to use the time machine by convincing her she'll just end up killing one of herself when her Ego clashes with her past self's ego.
* '''Exploited''': ???
* '''Defied''': Alexia takes pains to never mess up time.
* '''Discussed''': "I hate time travel. If we step on a butterfly we'll end up starting World War Three, and then the universe will implode."
* '''Conversed''': "I wonder why anyone uses time machines when it's so easy to make a time travel paradox."
* '''Deconstructed''': Time travel inherently creates paradoxes (paradoxi?) and is thus too dangerous to ever use. Realizing this, Alexia makes one last paradox to save the universe: she kills the inventor of the time machine.
* '''Reconstructed''': ... which was completely pointless: a paradox only seems impossible to human observers, the nth dimensional Time Beavers explain to Alexia that it's all just a giant TimeyWimeyBall, and she shouldn't worry too much about it.
* '''Implied''': Alexia attempts time travel. Cue the universe caving in on itself.
What? You can't head back to and read TemporalParadox! The universe might be destroyed!
