Line #25 PlayingWith/MyOwnGrampa


1	'''Basic Trope''': A character is their own ancestor thanks to time-travel.
2	* '''Straight''':
3	** Bob ended up going back in time and impregnating Diane, his grandmother, with his father Greg, thus becoming his own grandfather.
4	** Alice goes back in time and falls in love with her grandfather Matt, conceiving her mother Chloe and becoming her own grandmother.
5	* '''Exaggerated''':
6	** Multiple time travel incidents result in Bob becoming his maternal and paternal grandfathers.
7	** Alice [[ParentalIncest becomes her own mother.]]
8	** Thanks to a GenderBender [[ScrewYourself experience]], [[MindScrew Bob is both his father and mother]].
9	** Alice and Bob's grandparents only include themselves and their siblings.
10	* '''Downplayed''':
11	** Bob's actions in the past result in his grandfather and grandmother getting together, meaning he's responsible for his own conception.
12	** Bob goes back hundreds of years and becomes his own distant ancestor.
13	** Alice's actions in the past gave her parents the idea to name their child after her, thus becoming her own namesake.
14	** Bob and Alice are the reincarnations of their grandparents.
15	* '''Justified''':
16	** [[SurpriseIncest Bob didn't know Diane was his grandmother, and Alice didn't know Matt was her grandfather]].
17	** Bob is a perverted MadScientist who wanted to see what'd happen [[ForScience if one's ancestry]] has [[StableTimeLoop no origin]], and Alice had UsefulNotes/ElectraComplex on Matt.
18	** They discovered they are their own grandparents, so had no choice but to conceive their parents who they were parents of to prevent a TemporalParadox.
19	* '''Inverted''':
20	** [[GrandfatherParadox Bob kills his grandfather before he can breed, and Alice prevents her grandparents from meeting.]]
21	** Bob ends up marrying [[KidFromTheFuture his granddaughter Alex from the future]], thus Alex becomes her own granddaughter.
22	* '''Subverted''':
23	** Bob sleeps with his grandmother Stacy, but remembers to bring a condom.
24	** Alice meets Matt, and eventually they start dating, but when Matt asks Alice if she'd like to sleep with him, she refuses.
25	** Time travel creates a different universe, so they didn't conceive with ''their'' Stacy and Matt.
26	** Alice and Bob go back in time and both end up sleeping with their grandparents, however, when they realize that Matt and Stacy are their grandparents, they worry about the implications and Alice and Stacy take pregnancy tests. It turns out, they're not pregnant.
27	** Alice and Bob are stuck in time for a month, during which they sleep with their grandparents and Alice and Stacy become pregnant. However, it turns out via a DaddyDNATest that Alice is actually pregnant to George, a man she slept with before time travel, and Stacy is pregnant to Sid, Bob's real grandfather.
28	* '''Double Subverted''':
29	** Bob's condom broke, resulting in him becoming his own grandfather after all.
30	** She instead falls in love with Max, who turns out to be her real grandfather.
31	** Greg and Chloe end up in AliceAndBob's universe, and end up conceiving them there anyway.
32	** The tests gave false negatives.
33	** It turns out that Stacy and Sid's child was not Greg, but Bob's uncle Walt, and when they go back in time again, they conceive Greg and Chloe, making them their own grandparents, and Alice and George's daughter Charlotte...her own aunt?
34	* '''Parodied''':
35	** Bob's father/son Greg sues him for child support.
36	** Alice and Chloe are at a loss when it comes to celebrating "Mother's Day."
37	* '''Zig Zagged''': Greg's father is unknown, but his son Bob is one possible candidate.
38	* '''Averted''': No-one becomes their own grandfather/grandmother/ancestor.
39	* '''Enforced''': "We want to confuse the Hell out of our viewers. Let's make Bob his own grandfather!"
40	* '''Lampshaded''':
41	** "Bob, where the hell does your Y Chromosome come from?"
42	** "If you masturbate Alice, [[CrossesTheLineTwice is it incest?"]]
43	* '''Invoked''': Emperor Evulz realizes being your own grandparent makes you ImmuneToFate, so he goes back in time and seduces his grandmother.
44	* '''Exploited''': Emperor Evulz manipulates [[NighInvulnerability Bob]] into becoming his own grandpa, so he can just kill Diane and RetGone Bob from existence.
45	* '''Defied''':
46	** Someone makes the rules of time travel, which prevent anyone from being their own ancestor, and Alice and Bob stick by the rules.
47	** Alice and Bob refuse to have sex while time-travelling.
48	* '''Discussed''': "Isn't it kind of weird how all the time travelers worry about killing their grandparents?" "Well better that than worry about ''becoming'' their own grandparents, as then nobody at all would time travel."
49	* '''Conversed''': "What kind of sick person would even go back in time to seduce their grandparent?" "Well multiple factors could be at play, such as not recognizing their grandparent or being forced to fulfill a StableTimeLoop."
50	* '''Implied''':
51	** Bob is the [[IdenticalGrandson spitting image]] of his grandpa, who mysteriously disappeared after grandma Diane got pregnant.
52	** Alice doesn't have any kids that she knows of, but she has a vague memory of giving birth to a baby girl and naming her Chloe.
53	* '''Deconstructed''':
54	** Bob suffers birth-defects due to his temporal inbreeding.
55	** Alice [[HeroicBSOD is traumatized by the fact she slept with her own grandfather.]]
56	** Each iteration of this loop becomes more and more unstable until it devolves into a TimeCrash.
57	* '''Reconstructed''':
58	** Bob's birth-defects [[DisabilitySuperpower give him superpowers.]]
59	** Alice comes to terms with her incest, knowing it was necessary [[StableTimeLoop to exist in the first place.]]
60	** Alice & Bob use genetic engineering and carefully treat the pregnancy to avoid birth-defects & trauma.
61	* '''Played For Laughs''': Alice and Bob regularly remind their parents ''they're'' their parents to avoid getting punishments.
62	* '''Played For Drama''': Because of Alice and Bob, their grandparents Matt & Diane end up demeaned and disrespected, in turn causing their parent/child Chloe & Greg to grow up hating their missing parent because of the insults they received. Thus, Alice and Bob's parents don't take the truth very well.
