Alice has just met Bob, and although the two of them come from very different backgrounds, they have one very important character trait in [[CommonalityConnection common]]: Both of them have missing parents. It doesn't matter what the circumstances (although the circumstances might be very similar if only for plot convenience); one might have a MissingMom and the other a DisappearedDad, or maybe both of them have parents who were killed due to war violence, or maybe one or both of them never even knew their parents. Whatever the circumstances, this link between them is key to their relationship together.

Often, the "bonding" part of this trope is done in a scene designed to stir up some emotion, with the two characters alone together, maybe sitting on a hillside or something, and something in the conversation leads them to talk about their parents.

Variations of this can cover any missing relative, or anyone who is sufficiently close enough to a character that they consider each other family. A relatively common twist on this trope is a [[TheReveal revelation]] that the two characters are missing the same exact person. (e.g., [[Franchise/StarWars Luke and Leia]] [[Film/ReturnOfTheJedi learning that they are brother and sister]].)

A SubTrope of CommonalityConnection.

[[folder: Anime and Manga ]]

* In ''MahouSenseiNegima'', Negi and Asuna smooth out some initial conflict by bonding over their mutual parentlessness.
* In the ''NanohaStrikerS'' supplementary manga, Teana starts showing much more understanding and care (in [[{{Tsundere}} her own way]]) for Subaru after learning about the death of Subaru's mother in the line of duty, since she herself lost [[PromotionToParent her surrogate-parent brother]] in a similar fashion, in addition to her parents, who died earlier.
* A one-sided version in ''Manga/OnePiece''. In Usopp's introductory arc, Usopp, whose father had left his family to become a pirate and whose mother died of illness sometime afterward, befriends [[IllGirl Kaya]] to help her get over the recent death of both of her parents, having first-hand experience of what she was going through. However, the usage of this trope isn't brought up until the arc is over and Usopp has left the island both of them were living on, and not by Usopp himself, but by Kaya's butler, who had learned Usopp's back story from the other villagers and figured it out.
* In ''DragonballZ'', this is how Gohan and Videl get to know each other personally, as opposed to just being crime-fighting martial artists.
* In the ''{{Bokurano}}'' manga, [[VitriolicBestBuds Kanji and Ushiro]] got to know each other after encountering each other while visiting their mothers' graves. [[spoiler:Ushiro's biological mother, however, wasn't actually dead at the time]].

[[folder: Comic Books ]]

* Franchise/{{Batman}} and the first two Comicbook/{{Robin}}s bonded over their parents being violently killed in front of them.
** He also bonded with ComicBook/GreenLantern Hal Jordan the same way; for all the different ways they're at odds with each other, they're still boys who lost their fathers early on.
* Implied in one ''Franchise/StarWars'' comic starring Boba Fett. Boba's latest target tries to throw him off by pointing him in the direction of a possible Jedi in hiding. Boba tracks the man down and blows up his house, but discovers that the man is no Jedi. He is merely the son of a Jedi who died in the battle of Geneosis (the same battle in which Boba's father Jango lost his life) and was left with nothing but his father's lightsaber as a keepsake. The man starts to cry as he states that he had to grow up without a father, remarking that he doubts Boba would be able to understand. As Boba recalls the moment he held Jango's severed head as a child, the man's own son arrives on the scene. He asks Boba if he's going to kill them both. In the next scene Boba tracks down and finishes off his original target.

[[folder: Fan Fic ]]

* In Fanfic/FlyFree, [[Anime/OnePiece Robin]] helps a lot of the [[{{Anime/Naruto}} messed up kids in Konoha]] by sharing parts of her past or things she's encountered. In Sasuke's case, it was this paired with their over-arching standing of being the [[SoleSurvivor Sole Survivors]] of their respective homes (the Uchiha for Sasuke and Ohara for Robin).
* In ''Fanfic/PerfectionIsOverrated'', [[MaiHime Mai and Nao]] chance upon each other in the hospital, where Mai visited Takumi and Nao visited her comatose mother; Mai learns about Nao's comatose mother at this point. However, one thing that helps them come to an understanding with each other over time is the contrasts between them- Mai has taken care of Takumi since her parents' deaths while Nao has no one of the sort, and Nao's mother could one day awaken from her coma- realizing the difference in their circumstances helps them understand the other and see their own past decisions in a new light.
* In ''Fanfic/TheArianaBlackSeries,'' [[MarySue Ariana]] and [[SatelliteLoveInterest Neville]] first get together when she's depressed about her [[MissingMom dead mother]]/[[DisappearedDad absentee father]] and he tells her about his parents' [[DrivenToMadness mental health issues]].
* In ''Fanfic/EmpathTheLuckiestSmurf'', it's explained as the reason that Papa Smurf is the sole parent figure of a hundred Smurfs.
* In the [[WesternAnimation/MyLittlePonyFriendshipIsMagic MLP:FiM]] fan fiction ''Fanfic/OurTrueColors'', this is what cements the bond between Applejack and [[spoiler: Pinkie Pie]].

[[/folder]]

[[folder: Film ]]

* ''{{Footloose}}'' has a minor variation; Ren has a DisappearedDad, and Ariel has a dead brother. They bond over this while [[ItMakesSenseInContext screaming at a train]]. Ren and Reverend Moore (Ariel's father) also later have this scene together for a moment to establish that they are NotSoDifferent.
* ''{{Jumanji}}'' had Alan Parrish talking with Judy and Peter about their dead parents after learning his own parents have died.
* One of these leads to TheReveal in ''TheParentTrap''.

[[/folder]]

[[folder: Literature ]]

* In one story of ''Literature/{{TKKG}}'', two side characters do this.
* In ''Literature/ALittlePrincess'', Sarah calms the tantrum-throwing Lottie by bonding with her over their dead mothers.
* The lead characters of ''LeftBehind: The Kids'' bond together when their parents are either raptured or killed.
* In ''Literature/TheLordOfTheRings'' both Faramir and Éowyn lost their mothers as small children and their fathers (or father figures) in the Battle of the Pelennor Fields. They bond over it among over things in the Houses of Healing.

* ''Literature/GalaxyOfFear: Army of Terror'' has the Arranda kids and Luke Skywalker bonding over all of them being recent orphans.

* A variant in ''Literature/HarryPotterAndTheOrderOfThePhoenix:'' after the death of [[TheHero Harry]]'s ParentalSubstitute [[spoiler:[[MentorOccupationalHazard Sirius]]]], the only person who is really able to console him is [[CloudCuckooLander Luna]], who tells him about how her mother died. It marks the first time Harry feels sorry for Luna, since before she had come off as kooky at best and annoying at worst.

[[folder: Live Action TV ]]

* One of the (many, many) bonds Mulder and Scully share in ''Series/TheXFiles'' is that both lose their respective fathers early in the series.
* On ''Series/{{Bones}}'' one of the first times Brennan was shown sympathising with another human being was when she revealed to a Foster Kid (whose foster brother had been killed) that she had been in the foster system too.
* [[Series/{{Merlin}} Merlin]] and Gwaine do this over their deceased fathers.
** For that fact, same could be said about Merlin who has a DisappearedDad and Arthur who has a MissingMom.
* On ''Series/{{Leverage}}'' Parker and Hardison have this during "The Stork Job".
* In ''Series/{{Supernatural}}'' both Castiel and Dean have fathers who abandoned them at some point in their lives. However Castiel's dad is ''{{God}}''.
* In the first season of ''{{Glee}}'', Kurt and Finn bond over Kurt's dead mom and Finn's dead dad, Kurt telling Finn that he sometimes lies down on the floor next to the dresser that still smells of his mom's perfume, and Finn showing Kurt some of his dad's things. Later, Kurt's dad and Finn's mom marry each other.
* ''TheGeorgeLopezShow'', George is about to send Max's troublemaking friend Ricky home to his mother, only to find that like him, the mother is an alcoholic and the father abandoned them. Rather than leave Ricky with his mother (who is obviously very drunk), he offers to let him stay over for a few days and winds up arranging Ernie to be his foster parent.
* In ''Series/HouseOfAnubis'' it's surprising how long it took for two people to bond over their parental issues, as everyone seems to have them. In this case, it was Jerome and Joy.
* Subverted in ''Series/TheVampireDiaries''. Anna tells Elena about her plan to open the tomb containing Katherine so she can free her mother, who was imprisoned there a long time ago. Elena sympathizes with her, but Anna says "Yeah, I think we'll skip the dead mom bonding so you can start serving a purpose."

[[folder: Video Games ]]

* ''AceAttorneyInvestigations'': Miles Edgeworth and Kay Faraday. Both their fathers were lawyers who were killed in the courthouse when they were about ten years old. This parallel does not go unnoticed by Edgeworth.
* The first ''VideoGame/MegaManStarForce'' game has its fair share of this. Geo and Sonia bond over his missing dad and her dead mother. Geo and Pat have an almost-romance over Geo's missing dad and Pat being an orphan.
* A DummiedOut conversation in ''VideoGame/{{Mother 3}}'' has Kumatora and Duster muse about how none of the three human protagonists have mothers. Kumatora is genuinely an orphan, and Duster's mother seemingly died before the White Ship departed. Likewise Hinawa isn't even confirmed to be Lucas's genetic mother.

[[folder: Web Comics ]]

* In ''Webcomic/ElGoonishShive'' this way [[ChivalrousPervert Tedd]] and [[StrawFeminist Susan]] found [[http://www.egscomics.com/?date=2003-04-25 a common ground]]. This [[VitriolicBestBuds relationship]] somewhat improved later.

[[/folder]]

[[folder: Western Animation ]]

* ''WesternAnimation/AvatarTheLastAirbender'' loves this trope, usually with regard to Katara and Sokka's mother (who was killed in a [[TheEmpire Fire Nation]] raid of their colony):
** Katara and Haru, as Haru's father was taken away from his family by the Fire Nation due to laws against earthbending in his town. This leads Katara to help him and his dad, who is on the same prison rig as Haru is taken to, when he gets arrested for the same reason.
** [[ManipulativeBastard Jet]] [[SubvertedTrope attempts to use this]] to manipulate Katara and Sokka into destroying a town occupied by the Fire Nation.
** Katara and Zuko, during their LockedInARoom scene in the season 2 finale; when Katara mentions that the Fire Nation took her mother away, Zuko says, "That's something we have in common," and tensions cool for a while, [[SubvertedTrope until]] Zuko's FriendOrIdolDecision between siding with [[TheDragon Azula]] or making a HeelFaceTurn leads him to completely ignore all that bonding and side with Azula.
*** As a result, when Zuko sides with the Gaang for good, Katara's the last person to trust him until he helped her find her mother's killer.
** Mako and Asami continue the tradition in the SequelSeries ''WesternAnimation/TheLegendOfKorra''.
* In ''WesternAnimation/YoungJustice'', Zatanna's mother isn't in the picture, and she suddenly loses her father when he sacrifices himself to become the vessel of Doctor Fate, and prevent him from keeping hold of Zatanna. While Robin has been forbidden by Batman to reveal his secret identity (and, with it, the fact that his parents were murdered when he was nine), he's usually the one shown grieving with or comforting her. He had a crush on her already, but the show seems to imply that his empathy was what pushed them towards their kiss in the finale.
* An odd example from the 2012 ''WesternAnimation/{{Teenage Mutant Ninja Turtles|2012}}'': [[DarkActionGirl Karai]] is giving [[WeirdnessMagnet April]] a CurbStompBattle as April, near the breaking point, begins recounting all the weirdness and trouble she's had, ending with her (previously unmentioned) MissingMom. Something about this causes Karai (who also has no visible mother in her life) to hesitate for just a second, allowing April to knock her down a staircase and escape. But in a later episode, she still tries to kill her.
* ''WesternAnimation/{{Kaijudo}}'': Ray and Allie bond over Ray's DisappearedDad and Allie's MissingMom. That's how their friendship started.
