* ''[[Franchise/StarWars Star Wars]]'' is often accused of this, as seemingly every major character is revealed to be related or connected to one other in some way as the movies go on. It started with the dramatic, well-received reveal that Vader was Luke's father, followed up in the next movie with the not-as-well-received reveal that Luke's possible {{Love Interest|s}} was actually his ''sister''. The prequels continued the trend by establishing, among other things, that the lovable droids from the first trilogy were actually friends and companions to Anakin and Obi-Wan. Finally, the sequels had both the main character ''and'' villain be descended from major characters from the previous films.

-->'''Washout:''' This is an incredible coincidence, but the hunter who mistakenly killed your father was Henry Pfaffenbach, my father. I feel terrible. *holds a family picture with Mailman's head stuffed like a deer's on the wall in the background*

** And The Snow Queen is [[spoiler:Emma's foster-mother... wait, does this make her Elsa and Anna's cousin?]]
*** foster cousins, yes.

* ''VisualNovel/TwelveRiven'': [[spoiler:Boss is Narumi's adoptive father, Myuu and Mei are twin sister and brother, Narumi is their older sister, Maina is a physical manifestation of part of Narumi's consciousness, is dating Ohtemachi, who once dated Narumi. Chisato and Omega are Psi-Clones created from Myuu and Mei's DNA, Yuyu is the daughter of a friend of the Maina family, Renmaru is Myuu's childhood friend (boyfriend by the end of the game)... Yeah, practically every character is related in some way]].

* Encouraged for Muslim rulers in ''VideoGame/CrusaderKings III''. Because Muslim rulers and their vassals practice [[ExoticExtendedMarriage polygyny]], they tend to have large families with many children. Unlike with most other religions, a Muslim family has a -20 opinion penalty with their overlord's family if they're ''not'' in a marriage alliance by having one of their children married or betrothed to one of the overlord's children. If you have multiple vassals from the same clan you only need one marriage to satisfy all of them, luckily.

* Basically every present-day character in ''VisualNovel/FateStayNight'', although you can somewhat include many of the Servants as well. Where to begin. Shirou is schoolmates with Rin, Sakura, and Shinji. Shinji's younger sister is Sakura, [[spoiler:whose real older sister is Rin]]. [[spoiler:Shirou's adoptive father Kiritsugu is Illyasviel's biological father.]] Kirei was Rin's father's apprentice, [[spoiler:and Caren is his estranged daughter]]. [[spoiler:Rin's, Shinji's and Illya's ancestors were all partners who started the Holy Grail War together.]] Shirou's only friends at school are Issei and Shinji, who both happen to be the school's cool kids (as a side note, Issei has an old rivalry with Rin and Shinji has a crush on her), while Shinji [[spoiler:is Rider's temporary Master]] and Issei lives with and is soul brothers with [[spoiler:Kuzuki, Caster's Master]]. Shirou's Servant, Saber, [[spoiler:was Kiritsugu's Servant previously]], during which time [[spoiler:she met and was proposed to by Gilgamesh]], [[spoiler:who was originally Rin's father's Servant]]. Shirou was formerly in the Archery club with Shinji, Sakura, and Ayako, and Ayako happens to be Rin's old, close friend. Taiga is simultaneously Shirou's neighbor, childhood friend, guardian, homeroom teacher, and former club adviser, and her grandfather is an old acquaintance of Kiritsugu who lets Shirou do his bike maintenance. And I shouldn't even need to mention [[spoiler:[[FutureBadass Archer]] [[FutureMeScaresMe actually]] '''[[MyFutureSelfAndMe is]]''' [[IHatePastMe Shirou]]]], should I? And that's just the characters important enough to get face time and ignoring the relations to characters in [[Franchise/{{Nasuverse}} Nasu's]] [[VisualNovel/{{Tsukihime}} other]] [[Literature/TheGardenOfSinners works]].

* In ''VisualNovel/KaraNoShoujo'' it doesn't seem this way at first, but once you have the full story it becomes clear how much this applies. [[spoiler:Both serial killers were set in motion by the serial killer who got Reiji's wife. The second one knew Toko as a little girl and is not unlike her brother. He also killed another person who could be considered his sister, Mizuhara. Mizuhara's mother is one of the Mamiya family. Mamiya Shinzo was Misa's lover, and Misa was Rokushiki Makoto's sister. Rokushiki's fiancee was Stella's older sister, and Stella's family raised both Shinji and Toko for some time.]] This is not taking into account the stuff you know from the start like how everyone went to school together or still goes to school together and whatnot.

* ''Webcomic/{{xkcd}}'': [[https://xkcd.com/2608/ "Family Reunion"]] opines that all gatherings are family reunions because all living creatures are [[UsefulNotes/{{Evolution}} descened from a single common ancestor]]; Randall Munroe is at most a 35th cousin with every human at the depicted gathering, a seventeen thousandth cousin with the pet cat, and a fifty billionth cousin with the houseplant.

* In the ''Literature/WarriorCats'' series, considering that each clan has its own TangledFamilyTree, and that cats inside one clan are not allowed to mate with cats from other clans (though some still do), it is not surprising that after a few generations of mating with each other, almost everyone is related to one another inside any given clan, except for newcomers.

* ''Webcomic/LegendOfTheBlueDiamond'': Every named character, with the exception of the sisters Water and Fire and Willow's family, is related to every other named character.

** The Summers Family is by far the most extensive though: Corsair (father to [[Characters/MarvelComicsCyclops Cyclops]], Havok and Vulcan), Katherine Summers (wife of Corsair, mother of Cyclops, Havok and Vulcan), Cyclops, Havok, Vulcan, [[Characters/MarvelComicsXMan Nate Grey]] (alternate reality version of Cable (sorta) and clone of Jean Grey and Cyclops), [[Characters/MarvelComicsJeanGrey Jean Grey]] (wife of Cyclops), [[Characters/MarvelComicsMadelynePryor Madelyne Pryor]] (clone of Jean Grey and wife of Cyclops), Characters/{{Cable|NathanSummers}} (son of Cyclops and Madelyne Pryor), Jenskot (wife of Cable), Tyler Summers (son of Cable and Jenskot), Stryfe (clone of Cable, adoptive son of Apocalypse), Hope Summers (adoptive daughter of Cable), Rachel Grey (alternate reality daughter of Jean Grey and Cyclops), and Ruby Summers (future daughter of Emma Frost and Cyclops). Adam X may or may not be the half brother of Cyclops, Havok and Vulcan (though he was ''intended'' to be, it was never confirmed in the comics).
* ''Franchise/WonderWoman'''s recurring cast can start to feel this way, partially due to the inherently inbred nature of the Greek Gods, partially because new writers can't help but try to tie new characters to older characters, and partially because every writer seems to want to use different, often conflicting, bits of the original myths and occasionally confirm that Hippolyta still has her original mythological parentage (making her Ares' daughter), or hint that Wonder Woman is ComicBook/{{Hercules|Unbound}} or Ares' daughter. Other examples are how later writers had ComicBook/WonderGirl Cassie Sandsmark learn that Zeus is her father, or how Donna started out as an orphan adopted by Hippolyta before subsequent attempts to rewrite her connection to the family caused an infamous [[ContinuitySnarl/DonnaTroy Continuity Snarl]].

* Literally true for horse racing, as most of the famous events are for Thoroughbreds only, and in order to be considered a Thoroughbred a horse must have two Thoroughbred parents, as well as be descended from one of just three seventeenth-century stallions. Like all upperclass pastimes, the animals involved all have complete pedigrees recorded, so it is theoretically possible to determine exactly how closely related every horse is to every other horse of the race.

* Kalima is related to Caterina who is dating Aleksandr. Kalima and Caterina's other cousin is getting married to Keira's older brother. Fay and Doe are related to Caterina and Kalima through a distant ancestor who was a Champion of Erica. Erica is the Aunt of Kieran and Seraphine. Kieran is dating Kalima. This all occurs in the first book of ''Literature/{{Sekhmet}}

** Similarly, try this with ''Manga/TsubasaReservoirChronicle'' and its [[CloningBlues various]] [[MindScrew worlds]] [[MyOwnGrandpa and]] [[ReincarnationRomance other]] [[StableTimeLoop plot twists]] - you'll end up with horrible migraine.

* Alright, ''Manga/NegimaMagisterNegiMagi''. The whole thing deserves spoilers: [[spoiler:Negi and Asuna are related by blood, and Negi's dad's group has ties to Asuna, Konoka, Evangeline, Takamichi, and the Headmaster. Konoka's bodyguard/love interest Setsuna is the sempai of now-villainous Tsukuyomi. Chao is a time traveling descendent of Negi's, and helped create Chachamaru with Hakase. Zazie's EvilTwin sister is an underling of one of the BigBad's allies[[note]]said ally is also blood-related to Negi, Asuna and the rest[[/note]], Yuuna's mom was revealed to be a mage, and Misora was in on magic to begin with, as was Mana.]]

* In ''Anime/ImGonnaBeAnAngel'' [[spoiler:all the main characters and even villains turned out to be connected to each other in some way: starting with Yuusuke and Noelle, Yuusuke is in love with Natsumi who is obsessing over her dead brother Fuyuki. Fuyuki is really Raphael, who a teacher and a lover of Mikael, who in turn is a part of Noelle, who as you know, is in love with Yuusuke. Mikael, Noelle and Silky are parts of one angel soul, which makes something akin to siblings. Eros, Muse and Dispell are Silky's toys, living because of her power. And there's Noelle's family where noone is really evenblood-related.]].

** Most of the important characters are revealed to be a part of the same family line or have the same ancestors by Part II of the series. The most important is of course the fact that [[spoiler:the Uzumaki Clan is an offshoot of the Senju Clan, who in turn is a sister clan of the Uchiha Clan; both of them are descended from the children of the Sage of the Six Paths, the legendary founder of the ninja arts. This thus makes Naruto not only related to the Uchiha (and his best frenemy, Sasuke), but the First and Second Hokage as well.]]
** Naruto [[spoiler:is not the only Uzumaki left: Nagato and Karin are also descended from the clan even if they don't carry the surname anymore. Also Tsunade, whose grandfather married Mito ''Uzumaki'' before settling down to create Konoha with Madara Uchiha. In fact, Mito was the first host of the Nine Tails, being chosen specifically because she's an Uzumaki, and actually lived long enough to personally meet with and give advice to her successor, Naruto's mother Kushina.]]
** The final arc gives more uncovered relationships: [[spoiler:The Sage, Hagoromo was one of the twin sons of Kaguya, the first person (actually a celestial alien) who was able to control chakra. He inherited his mother's Rinnegan, while his brother, Hamura, inherited her ''Byakugan'' which he passed down to his descendants, the ''Hyuga Clan''. In short, Naruto is also distantly related to his eventual wife, Hinata.]]

** All beaten by this particularly nice statement: [[spoiler:''Yhwach is the son of the Soul King[[note]]the symbol and possibly ancestor of every souls in the universe[[/note]]''. That alone should tell you the extent on how messed up the ''Bleach'' universe is, with everyone trying to kill their relatives here and there.]]

* In ''Anime/FlipFlappers'', Almost everyone in the series is related in some way. For starters: Yayaka, Cocona's childhood friend, is part of Asclepius, the organization Flip Flap opposes. [[spoiler: Mimi is Cocona's mom and Papika's old friend. Dr. Salt turns out to be the husband of Mimi, making him Cocona's estranged father. Cocona's grandma is a surveilance robot built by Asclepius, which is led by Salt's insane father. The Amorphous pieces are actually shards of Mimi, so since Toto, Yuyu, and Nyunyu were created from the pieces, they're Cocona's artificial "siblings".]] The only people completely unrelated to this family tree are Sayuri, Hidaka, and Bu-chan.

** The Summers Family is by far the most extensive though: Corsair (father to Comicbook/{{Cyclops}}, Havok and Vulcan), Katherine Summers (wife of Corsair, mother of Cyclops, Havok and Vulcan), Cyclops, Havok, Vulcan, [[Comicbook/XMan Nate Grey]] (alternate reality version of Cable (sorta) and clone of Jean Grey and Cyclops), Jean Grey (wife of Cyclops), Madelyne Pryor (clone of Jean Grey and wife of Cyclops), Comicbook/{{Cable}} (son of Cyclops and Madelyne Pryor), Jenskot (wife of Cable), Tyler Summers (son of Cable and Jenskot), Stryfe (clone of Cable, adoptive son of Apocalypse), Hope Summers (adoptive daughter of Cable), and Rachel Grey (alternate reality daughter of Jean Grey and Cyclops), Ruby Summers (future daughter of Emma Frost and Cyclops). Adam X may or may not be the half brother of Cyclops, Havok and Vulcan (though he was ''intended'' to be, it was never confirmed in the comics).
* ''Franchise/WonderWoman'''s recurring cast can start to feel this way, partially due to the inheriently inbred nature of the Greek Gods, partially because new writers can't help but try to tie new characters to older characters, and partially because every writer seems to want to use different, often conflicting, bits of the original myths and occassionally confirm that Hippolyta still has her original mythological parentage (making her Ares' daughter), or hint that Wonder Woman is ComicBook/{{Hercules|Unbound}} or Ares' daughter. Other examples are how later writers had ComicBook/WonderGirl Cassie Sandsmark learn that Zeus is her father, or how Donna started out as an orphan adopted by Hippolyta before subsequent attempts to rewrite her connection to the family caused an infamous [[ContinuitySnarl/DonnaTroy Continuity Snarl]].

* ''[[Franchise/StarWars Star Wars]]'' is often accused of this, as seemingly every major character is revealed to be related or connected to one other in some way as the movies go on. It started with the dramatic, well-received reveal that Vader was Luke's father, followed up in the next movie with the not-as-well-received reveal that Luke's possible LoveInterest was actually his ''sister''. The prequels continued the trend by establishing, among other things, that the lovable droids from the first trilogy were actually friends and companions to Anakin and Obi-Wan. Finally, the sequels had both the main character ''and'' villain be descended from major characters from the previous films.

** By the end of the story [[spoiler:the PowerTrio are all Weasleys by marriage or blood, with fraternal and legal connections to the Delacour, Lupin, and Tonks families.]]

* In ''Literature/GreatExpectations'', [[spoiler:Estella]] turns out to be the child of two characters Pip has had random encounters with: [[spoiler:Abel Magwitch]] and [[spoiler:Molly]]. In addition, the man who left Mrs. Havisham at the altar turns out to be [[spoiler:the second escaped criminal that Pip saw when he first met Magwitch.]]
* In ''Literature/FortHope'', protagonist Greg is related to half of the cast. The book does start off with his trying to get to know his family, after all. Towards the end of the book, it is revealed that [[spoiler:Emma is related to the other half of the cast, including her longtime best friend and the book's big bad.]]

* ''Series/{{Lost}}'' has had a few. Jack and Claire [[spoiler:are half-siblings.]] We had met Widmore, Eloise, and Daniel in seasons 2, 3, and 4, respectively, but it wasn't till season 5 that we found out Widmore and Eloise [[spoiler:are Daniel's parents.]]
** Which makes Penny [[spoiler:Daniel's half-sister]], and Desmond and Daniel- who were already good friends- [[spoiler:brothers-in-law.]]
** Hilariously enough, [[spoiler:this means that if Jack and Kate's marriage had worked out, they could have gotten custody of Aaron legally.]]

** And then we find out that [[spoiler:Peter Pan is his ''great''-grandfather.]] And [[spoiler:the Wicked Witch of the West is Regina's half-sister.]]

* In ''VideoGame/DigimonStoryCyberSleuth'', [[spoiler:the protagonist, Arata, Nokia, Yuuko, and Yuugo were the five children that were the participants of the first EDEN beta test that ended up with them discovering a portal to the Digital World and left traumatized by the events that transpired in them which led to Yuugo becoming patient zero of EDEN syndrome, which forced the scientists to wipe off their memories to hide the horrible incident.]] Coincidentally, they all meet together in person in their late teens [[spoiler:with half of them meeting in the very same place they entered the Digital World]], none the wiser of what happened back then.

* ''VisualNovel/TwelveRiven'': [[spoiler:Boss is Narumi's adoptive father, Myuu and Mei are twin sister and brother, Narumi is their older sister, Maina is a physical manifestation of part of Narumi's consciousness, is dating Ohtemachi, who once dated Narumi. Chisato and Omega are Psi-Clones created from Myuu and Mei's DNA, Yuyu is the daughter of a friend of the Maina family, Renmaru is Myuu's childhood friend (boyfriend by the end of the game)... Yeah, practically every character is related in some way.]]

* ''VideoGame/OdinSphere'': [[spoiler:Of the main characters, Gwendolyn marries Oswald, Cornelius and Velvet are lovers, and Mercedes has a thing for Ingway. Of course, Velvet and Ingway are twin siblings, and Gwendolyn is their half-sister on their father's side. As if that wasn't enough, it turns out that Cornelius had a long-lost first cousin... Oswald. Who was adopted by a fairy noble who happens to be the first cousin of Mercedes.]] Part of the fun in ''Odin Sphere'' is figuring out the ridiculous family trees.

* ''VideoGame/TheNeverhood'': [[spoiler:Everyone present in the game is related, excepts for animals and robots. Klaymen and Klogg are brothers (due to both being created by Hoborg), Hoborg is their father (due to being their creator), and Willie Trombone is their cousin (by virtue of his father Ottoborg being Hoborg's brother).]]
* ''VideoGame/TheCouncil'' has several characters revealed to be related in the last two episodes. [[spoiler: BigBad Mortimer turns out to be the father of protagonist Luis, his mother Sarah ([[FamilyRelationshipSwitcheroo making her his sister]]), his LoveInterest Emily and her twin sister Emma. Sir Gregory Holm is Mortimer's brother, and von Wölner is Holm's son, making them Luis' uncle and cousin respectively. Mortimer and Holm are also the direct offspring of none other than UsefulNotes/JesusChrist, who may show up in the final episode.]]

* 12 out of the 18 characters ''VisualNovel/UminekoWhenTheyCry'' starts out with are direct family of each other whether by blood or by marriage. Then again, [[JustifiedTrope most of the story takes place during a family conference]]. (The other 6 characters are five of the family head's servants, and a friend of his.) As for the characters who show up later (and there are a lot), a number of them are Meta characters, two characters are [[{{Expy}} based on characters from a previous work]], [[spoiler:and a number of characters are really one person going under different identities.]]
* Basically every present-day character in ''VisualNovel/FateStayNight'', although you can somewhat include many of the Servants as well. Where to begin. Shirou is schoolmates with Rin, Sakura, and Shinji. Shinji's younger sister is Sakura, [[spoiler:whose real older sister is Rin]]. [[spoiler:Shirou's adoptive father Kiritsugu is Illyasviel's biological father]]. Kirei was Rin's father's apprentice, [[spoiler:and Caren is his estranged daughter]]. [[spoiler:Rin's, Shinji's and Illya's ancestors were all partners who started the Holy Grail War together]]. Shirou's only friends at school are Issei and Shinji, who both happen to be the school's cool kids (as a side note, Issei has an old rivalry with Rin and Shinji has a crush on her), while Shinji [[spoiler:is Rider's temporary Master]] and Issei lives with and is soul brothers with [[spoiler:Kuzuki, Caster's Master]]. Shirou's Servant, Saber, [[spoiler:was Kiritsugu's Servant previously]], during which time [[spoiler:she met and was proposed to by Gilgamesh]], [[spoiler:who was originally Rin's father's Servant]]. Shirou was formerly in the Archery club with Shinji, Sakura, and Ayako, and Ayako happens to be Rin's old, close friend. Taiga is simultaneously Shirou's neighbor, childhood friend, guardian, homeroom teacher, and former club adviser, and her grandfather is an old acquaintance of Kiritsugu who lets Shirou do his bike maintenance. And I shouldn't even need to mention [[spoiler:[[FutureBadass Archer]] [[FutureMeScaresMe actually]] '''[[MyFutureSelfAndMe is]]''' [[IHatePastMe Shirou]]]], should I? And that's just the characters important enough to get face time and ignoring the relations to characters in [[Franchise/{{Nasuverse}} Nasu's]] [[VisualNovel/{{Tsukihime}} other]] [[Literature/TheGardenOfSinners works]].
* ''VisualNovel/{{Infinity}}'' series: In ''VisualNovel/{{Ever17}}'', [[spoiler:Hokuto and Sara are Tsugumi and Takeshi's children. You is the mother of her clone. You and Coco's father worked together in Lemu and are the reason both are there. And may have designed Sora and are therefore her "father" in a sense. Sara and You went to the same high school.]] But [[spoiler:Kaburaki]] is just some [[spoiler:guy.]] [[spoiler:Unless, [[{{fanon}} as some believe]], he and the older You had a relationship of some sort going.]]

** ''VisualNovel/ApolloJusticeAceAttorney'' really liked this trope. [[spoiler:Apollo is the half-brother of Trucy [[IHaveManyNames Enigmar/Gramarye/Wright]], who was adopted by Phoenix Wright. Their mother Thalassa was married to Zak, who was accused of killing her father Magnifi Gramarye. This accounts for pretty much all the main characters besides Kristoph and Klavier... who are brothers]].
** Oh, and don't let us get started on [[spoiler:the Feys. Mia, Maya, Pearl, Morgan, Elise Deauxnim, serial killer Dahlia Hawthorne (who was ''coincidentally'' jailed by aforementioned Mia), her identical twin Iris (who was Phoenix Wright's girlfriend in university while ''posing as Dahlia'')... Pretty much ''all'' females who appear in more than one case in the first three games, save Maggey, Lotta, Oldbag, and Adrian, can be safely assumed to be a Fey. Turns out even ''Bikini'' is one. And those who are ''not'' Feys are sure to have [[OneDegreeOfSeparation some kind of connection]] to them. Especially bad with Phoenix, whose life seems to have been ''determined'' by the Fey Clan ever since loooong before he knew that it even existed.]]
** ''VisualNovel/PhoenixWrightAceAttorneySpiritOfJustice'' takes this even further. The royalty of the Kingdom of Khura'in are distant relatives to the Fey Clan, as both are descended from the Holy Mother. Going into specific cases, [[spoiler:Nahyuta Sahdmadhi is the son of the rebel leader Dhurke Sahdmadhi and the former queen Amara Sigatar Khura'in, Princess Rayfa Padma Khura'in is his sister, and she is effectively adopted by the current queen Ga'ran Sigatar Khura'in and Justice Minister Inga Karkhuul Khura'in. Apollo's biological father Jove Justice died in the fire that supposedly killed Amara, and he was taken in by Dhurke for a time.]]

* ''Webcomic/GirlGenius'': The marriage of Agatha's parents - Bill Heterodyne and Lucrezia Mongfish - means Agatha is related in some way to a large chunk of the cast. {{Lampshaded|Trope}} when the beans are spilled on her parentage by [[https://www.girlgeniusonline.com/comic.php?date=20040823 one character]] who realizes he and Agatha are cousins now. The PrecursorHeroes duo that everyone in Europe tells their kids bedtime stories about are Agatha's dad and uncle. The setting's BigBad dubbed "the Other" is Agatha's [[spoiler:mother, secretly]]. The fake Heterodyne heir Zola is ironically Agatha's [[spoiler:cousin, but on the Mongfish side]]. Those in the main cast who aren't related to Agatha by blood are at least related to an old friend of her parents.

* Basically every present-day character in ''VisualNovel/FateStayNight'', although you can somewhat include many of the Servants as well. Where to begin. Shirou is schoolmates with Rin, Sakura, and Shinji. Shinji's younger sister is Sakura, [[spoiler:whose real older sister is Rin]]. [[spoiler:Shirou's adoptive father Kiritsugu is Illyasviel's biological father]]. Kirei was Rin's father's apprentice, [[spoiler:and Caren is his estranged daughter]]. [[spoiler:Rin's, Shinji's and Illya's ancestors were all partners who started the Holy Grail War together]]. Shirou's only friends at school are Issei and Shinji, who both happen to be the school's cool kids (as a side note, Issei has an old rivalry with Rin and Shinji has a crush on her), while Shinji [[spoiler:is Rider's temporary Master]] and Issei lives with and is soul brothers with [[spoiler:Kuzuki, Caster's Master]]. Shirou's Servant, Saber, [[spoiler:was Kiritsugu's Servant previously]], during which time [[spoiler:she met and was proposed to by Gilgamesh]], [[spoiler:who was originally Rin's father's Servant]]. Shirou was formerly in the Archery club with Shinji, Sakura, and Ayako, and Ayako happens to be Rin's old, close friend.

And I shouldn't even need to mention [[spoiler:[[FutureBadass Archer]] [[FutureMeScaresMe actually]] '''[[MyFutureSelfAndMe is]]''' [[IHatePastMe Shirou]]]], should I?

[[folder:Live Action TV]]

* ''Series/{{Heroes}}'' is another example. With each season, more familial bonds spring up between main characters that originally lived on completely different continents.
** Then again, powers are genetic, so it's a convenient way to introduce a new character with powers by saying they're a relative.

* ''Series/ThePretender'' where Jarod has an evil long lost older brother Kyle and a sister Emily. His arch nemesis Ms. Parker has an evil long lost twin brother who was separated at birth Mr. Lyle. Ms. Parker and Mr. Lyle's mother Catherine has a son named Ethan with Jarod, Kyle and Emily's father Charles. Mr. Parker the supposed father of Ms. Parker and Mr. Lyle turns out to be sterile and thus not their father. Their actual father is Mr. Raines who is the long lost brother of Mr. Parker but who was raised in foster care. Mr. Raines and his wife Edna also have a daughter named Annie. Mr. Lyle and his supposed father (but actually his uncle) have both slept with Brigitte and it isn't clear who her baby's daddy is. Oh and Jarod also has a clone.

* Taken to an absurd degree in ''Series/{{Dark}}'' where [[spoiler: the four main families (the Tiedemanns, the Dopplers, the Kahnwalds and the Nielsens), are not only revealed to be related to each other, they are also simultaneously each others' ancestors and descendants thanks to a copious helping of TemporalParadox and other TimeTravelTropes in play]]. The only characters unrelated are [[spoiler: Regina, Katharina, Peter and Bernadette]]. Consequently, they are the only characters who [[spoiler: don't get RetGone when the four families are wiped off the timestream.]]

* On ''Series/{{Revenge}}'', it is eventually revealed that Charlotte, daughter of Victoria and Conrad Grayson, was [[spoiler:fathered by David Clarke, making her Emily's paternal half-sister.]] Given Emily's marriage to Daniel, this results in both of Charlotte's half-siblings becoming her in-laws. Also, due to the identity swap between Emily Thorne and Amanda Clarke, Fauxmanda becomes the legal sister of Charlotte, daughter of Kara and David and wife of Jack. Emily is also made godmother to Fauxmanda and Jack's son Carl.
