Daddy Had a Good Reason For Abandoning You

Parental Abandonment, by its nature, usually excludes the parent from having much of a role in a character's story. If the backstory involves a child wallowing in Angst because of having no parents, to bring them back and treat everything as being hunky-dory sort of dilutes the origin story's dramatic impact.

Sometimes, though, a parent can be brought back through use of a proper excuse. A parent who we have seen or heard nothing of in some time may suddenly re-appear and explain that there was, in fact, a very good reason for the abandonment- but for various reasons, the details could not be revealed until just this moment. This is particularly important if child is going to follow in their parent's footsteps, since we would normally expect them to be bitter if this is the career that caused them to get abandoned in the first place.

Frequently the reason turns out to be Mum never informed Dad of their baby's existence for reasons that can range from not being sure WHICH partner was the father (a My Two Dads scenario), a desire to keep said infant all to herself, misguided 'kindness' of the 'a baby will ruin his life' nature or unresolved hostility towards him or all men.

This trope straddles a thin line - it can come off as extremely contrived unless said excuse is very, very convincing. In order for it to work there must be an explanation as to why no one bothered to bring it up until just the last minute. See also Glorified Sperm Donor for a form this can take when it's handled badly.

Sounds like but has nothing to do with taunting someone about having some real or imagined flaw which leads to the parents not loving them enough.

Anime and Manga

 * Jolyne Kujo from Part 6 of JoJo's Bizarre Adventure resents her father, Jotaro Kujo, for being absent for most of her childhood. Although partly due to work reasons, Jotaro also didn't want her getting mixed up in the supernatural troubles that he's frequently a part of.
 * Ranma's mother in Ranma One Half. Here the excuse seems to be "your dad insisted I not be around to be nice to you since it would make you less tough".
 * Somewhat justified in that Nodoka claims to have received constant letters from Genma all throughout Ranma's childhood, which stopped just about the time he and Ranma headed for China --and their absence is why she went personally to the Tendo home. So while she can be excused for not contacting Ranma personally earlier, readers realize that this makes Genma an even bigger bastard because he deliberately kept Ranma unaware of his own mother despite writing to her regularly.
 * In Mazinger Z and Great Mazinger it is both played straight and subverted:
 * It is played straight with Kenzo. His sons, Kouji and Shiro grew up believing their parents had died cause a laboratory experiment that went wrong. However, Kenzo's father saved his son's life by turning him into a cyborg. However, neither of them told Kouji and Shiro he was alive because It was not a bad reason, even if it was somewhat weak because Juzo was also building another Humongous Mecha and he raised them, even if he hired a maid because he was nearly always absent. When Kenzo revealed the truth to his little son, it took a long while for Shiro forgiving him. Though Kouji forgave him right away.
 * It is subverted with Kouji and Shiro's mother. In episode 90 from Mazinger Z, their mother appeared in the Institute, revealing she was alive and asking meeting her sons before telling them why she let them believe she was dead during years. Shiro was happy of getting his mother back, but Kouji was distrustful.
 * Done with Hohenheim in the anime version of Fullmetal Alchemist.
 * Also done in the manga where he He was also trying to
 * In the anime version of Angelic Layer, Misaki's Missing Mom Shuko is revealed to have and hence hasn't seen her daughter for years. This is notably exclusive only to the anime, while in the manga Shuko's excuse is that she's pathologically shy. The manga explanation is cuter, but the anime explanation makes more sense.
 * Played mostly straight in Code Geass with Kallen Stadtfeld
 * Played with in R2, where Lelouch
 * In Samurai Champloo, Fuu's father,, has a very good excuse -
 * In Naruto, Naruto's father had what he believed was a good reason...   Turns out that his mom is not only dead, but
 * Actually that was only part of the reason, he also did it because sealing it inside Naruto was the best way to prevent a potential fourth world war.
 * In the Star Village filler arc, Sumaru's parents attempt to steal the star in order to stop the star training that kills most of those who use it, but get discovered by the Hoshikage, who has them leave the village in order to watch over the star from afar and intervene if someone plans on using it again. Sumaru grows up thinking that his parents died defending the star; his father does die from the lingering effects star training, and his mother indicates that she can't stay with him if she could die at any time. His mother returns to steal the star when the star training resumes after Akahoshi kills the Hoshikage, and dies trying to recover the star.
 * In One Piece, Luffy's Disappeared Dad turns out to be
 * Considering what the World Government did on the island where they only suspected, I say he made a damn good choice.
 * Ussop father's abandoned him and his mother and never returned. Luffy then convinces Ussop that his father had a good reason for leaving him, since he was doing some pirate-stuff, up to the point where Ussop gets proud of him.
 * In The Vision of Escaflowne, Failure Knight Allen Schezar was badly traumatised by his sister's kidnapping and his mother's Death by Despair, and hates his Disappeared Dad for leaving the family.
 * Played straight as an arrow in Mobile Suit Victory Gundam at least twice. Hangelg Ewin, the father of series protagonist Üso Ewin, was actually . Likewise, Üso's mother, Mueller Miguel, . This rather neatly explains why Üso was practically left alone with his best friend Shakti Kareen,, to practically raise themselves during their early teenage years.
 * Also more or less used in Mobile Suit Gundam F91, where Monica Arno is the mobile suit engineer that creates the Gundam in the title. Her youngest daughter Reese seems to understand it, but her eldest son Seabook is understandably pissed off at her. The fact that  doesn't help.
 * In Pokémon Special, Ruby has a deep resentment for his father, Norman, for leaving the family for five years.
 * Gale, from Rave Master left his family when Haru was one in order to find the Rave stones, which is revealed fairly early on in the manga (or 15 years after he left. Why did no one tell Haru sooner?) This explanation alone is still unacceptable to Haru. When he actually meets Gale and learns that he left to find Rave in order to stop his Big Bad Friend, the leader of Demon Card, Haru accepts him as a father.
 * It kinda helped that Gale thought that the Dark Bring implanted in him by King could have created a second Overdrive at any moment, and thus wanted to be as far away from anyone as possible, especially his beloved children.
 * Averted in Neon Genesis Evangelion. It seems like they're setting Gendo up for this one when, right before, he explains his reasons for ignoring his son for like a decade. It's averted because: 1) It's way too late by then, and 2) his Freudian Excuse   don't really fly very well with the majority of the fans, and he seems well aware of the fact.
 * If you're wondering what his excuse was, it was.
 * Bokurano. . That's all. Each medium gives a different reason, but they're all pretty good.
 * Goku from Dragonball Z spends most of Gohan's and pretty much all of Goten's childhood's dead or off training
 * Though when he is around/alive, he really does try to be the best father he can to them. Points for effort, though his Spirited Competitor causes issues in what he thinks are good parenting decisions - he learns his lesson when he goes too far during the Cell saga, just in time to realize his folly and sacrifice himself for his son. Until then, though, his former archenemy comes off as a better parent to his son than he is.
 * In Yu-Gi-Oh! 5D's Yusei's father
 * Although we don't know the exact circumstances involved with Hinagiku and Yukiji's being abandoned by their birth parents in Hayate the Combat Butler, Hinagiku firmly believes that they had a good reason for leaving them behind. Yukiji doesn't seem to agree.

Comics

 * In The DCU, the Persuader's father left her mother because she was abusive towards both him and the young Persuader herself. However, her threats to rough herself up and say he did it if he even thought about taking their daughter convinced him that leaving her with that monster was a better alternative to living on the run with him. They eventually get reunited in a Crowning Moment of Heartwarming before the Persuader's boss kills her father just for kicks.
 * Cyclops of the X-Men: Daddy had been kidnapped by aliens, and was too busy being a Space Pirate, growing a kickin' stache and seducing his feline first mate to find his way back to Earth. Well, we said he had a good reason for abandoning you, not necessarily for staying away.
 * Cyclops' father assumes both of his children have fallen to their deaths, because their parachute was on fire. That is the last thing he sees before the aliens beam him off his plane. He does not learn Scott and Alex are still alive until they have both reached adulthood. So up to that point, he has a good reason not to be there for them. However, as soon as he finds out they are alive, he asks Jean Grey not to tell his children, because this would supposedly be for their own good. When Scott finds out anyway a few months later he is mightily pissed off.
 * Sinestro left his family to spare them from being associated with an intergalactic criminal.
 * Batman does the exact opposite: rather than abandoning his adopted sons, he tends to be just enough of a Jerkass that they go away themselves. In his mind, it's for their own good--the less attached they are to him, the less painful it will be when he dies, and Batman knows that all it takes is one lucky shot to finish him off. So it's more like Daddy Had a Good Reason To Be An Ass, which makes perfect sense when you think about how he became Batman in the first place.

Fanfiction

 * In Whispers in the Dark, a popular Percy Jackson and The Olympians fanfiction, Taylor is told that her father is dead only to find out that all this time, he's been alive and on Kronos' side. Somewhat justified in the fact that Luke didn't even know that he had a daughter until he saw Taylor and noticed that she had his Blue Eyes.
 * Nobody Dies Mommy had a good reason for abandoning Shinji...a basement full of Eldritch Abominations out to kill him (although why she didn't kill them instead of abandoning her son and possibly endangering the planet is a question unasked).
 * That would require a mother of a young child to murder several children the same age as her kid.
 * All too often handwaved in the "Adopted Hermione" subgenre of Harry Potter fanfic: Hermione learns that she's not only adopted, but "really" a Pureblood. In roughly nine such stories out of ten, no reason is ever given for her birthparents' relinquishing her -- except possibly a vague assertion that it was "for her own protection".

Film

 * Inverted in The Journey of Natty Gann: everyone else assumes Natty is an abandoned child. She knows otherwise.
 * Star Wars has Obi-Wan's infamous Jedi Truth, leading to the big reveal. But Anakin had no choice but to "abandon" Luke and Leia, because he didn't even know that they were still alive! As soon as he learned otherwise, he planned a nice family bonding experience so that they could get to know each other.
 * And of course we can't forget Leia, whose other daddy had an equally good reason for "abandoning" her...
 * Invoked in The Truman Show, where the writers decide to bring back Truman's father after he'd "died" at sea. This is explained through Easy Amnesia, and his just then getting over it.

Literature

 * This is the main theme of the King Arthur myth, where the young Arthur is abandoned by his father Uther Pendragon to be raised by Merlin. The reason for this varies depending on which version of the Arthur myth is read, but, canonically, it is because as a bastard son of Uther the succession would be in doubt and/or Arthur's life would be in danger if Uther produced a later legitimate son with Ygraine.
 * Played with in the second book, The Wizard Heir, of Cinda William Chima's Heir Trilogy. Because Seph's mother,, was fighting the system of the Wizard Guilds at the time he was born, she knew he would be in danger if anyone ever found out his parentage, and thus leaves him to a foster mother to keep him safe. Seph's father,  , didn't even know  had   because she disappeared on him after finding out she was pregnant.
 * Susan Cooper's The Grey King. Bran Davies is in truth the son of : he was brought forward in time and left in the 20th century by his mother after she betrayed his father. She had to leave him because she was going to find sanctuary in a convent.
 * In the Warchild Series, Captain Azarcon isn't around to raise his son Ryan (boy do people in fiction have tough parental issues with that name) because he's busy fighting a war against pirates and aliens.
 * In Harry Potter, Dean Thomas's father was an example of this.  Dean never finds out about this.
 * Neither do most readers, because this info is Word of God. It was going to go in but didn't really fit anywhere in the plot, leading J.K. to build up Neville's subplot instead. (Which also sort of fits this trope, if not perfectly.)
 * Five words - Percy Jackson and The Olympians.
 * Which includes its sequel series, The Heroes of Olympus.
 * Good reason? I can see the Big Three having good reasons to keep their demigod kids existences a secret. But what excuse do all the other gods have?
 * The threat of monsters coming to kill their children comes to mind.
 * But some is just being dicks.
 * I believe that's the norms when it comes to Greek Gods.
 * In Dinoverse, the rebellious graffiti artist Janine resents how her mother is often not at home, forcing her to miss school in order to prepare the hotel for guests herself. As it turns out, her mother is keeping Janine from getting in trouble over the graffiti - she never confronted her daughter because she feared Janine would run away.
 * The father of Demon Princess's protagonist was first in line for the throne, which also carried the responsibility of making sure nothing bad gets through portals to the human world. The way it's run is that when the current demon king/queen dies, the heir is immediately transported to the castle and can never leave. While he was with the protagonist's mother, his father died and he was called back, giving him no time to explain or say good-bye. He decided that she wouldn't even believe the explanation, so never made contact with his family until he learned about his daughter and her latent powers.
 * In Animorphs Tobias's father, Elfangor, had to leave him because he was being sent back to the Yeerk war by the Ellimist. The timeline was changed back to what it should have been, but Tobias still remained.
 * In The Historian the primary narrator, a young woman in the 1970s, was raised by her diplomat father because her mother died when she was an infant. You find out that
 * In Michael Flynn's Up Jim River, the harper, having heard the story in The January Dancer, knows that her father had an excellent reason -- but points out that her mother didn't know it.

Live Action TV

 * Victor with Adam on The Young and The Restless. Here, Adam's mother specifically asked Victor have no part in Adam's life, but charged Victor to take care of Adam on her deathbed. Not really sure why- it's a Soap Opera so her reasons for this were probably explained like, ten or twenty years ago.
 * Same with Paul and Heather. He was asked to stay out of Heather's life completely at her mother's request.
 * The Knight Rider remake has the character from the original show giving his son an It's Not You, It's My Enemies excuse for not being around.
 * Played with on Brothers and Sisters.  Here it's not really even a justification, but rather an explanation. Everyone still thinks William is a dick after this is revealed.
 * In Alias, Sydney has a rocky relationship with her father, Jack. It's implied he wasn't around much while she was growing out. Turns out he's a CIA agent fighting to save the country. And he was also in prison for part of time. Her mother, Irina, wasn't around because she faked her death and defected back to Russia.
 * In The Sarah Jane Adventures, Sarah Jane's parents abandoned her to kill themselves by car crash, fixing the Timey-Wimey Ball and saving the world from being devastated by aliens.
 * Likewise Rose's dad, on Doctor Who.
 * It happened twice in Charmed
 * The sisters father was kept away by a spell cast by grams.
 * Paige was given up because of the believe her existence would screw up destiny. Some can't help but wonder whether the issue was more fear about the wrath of the elders (which would also be a valid reason, just a bit more selfish).
 * Variant in Bones. Cam, it turns out, was an honorary stepmom to the daughter of her very serious boyfriend, but left the relationship (and, by proxy, the girl) when it turned out he had cheated on her. When the man was murdered and the team put on the case, the daughter is now a teenager and very annoyed at Cam
 * Also in Bones, both of Brennan's parents were being hunted by the gang of criminals they used to work with.
 * Then there are cases where the other parent forces your hand, as with Michael on Lost.
 * Or Miles, whose father makes his mother take him off the island to save their lives.
 * Happened on Criminal Minds with Reid's Disappeared Dad, whom everyone assumed left due to his mom's mental problems.  You're on your own to decide whether that's a good reason or not; Reid accepts it as a reason, but it's not clear that he thinks it's a very good one.
 * In Chuck.
 * And the reason their mom left them?
 * Done very sympathetically on an episode of Lie to Me where the team investigates a congressman who has spent 80 grand on a prostitute. However, they find out that he's never had sex with her, and was giving her the money to get her out of that business. She doesn't know that he's her father, and he is portrayed as someone who gave up his child for adoption but regretted it. The fact that he has no hesitation to sacrifice his reputation and political career in order to protect her from the scandal counts a lot toward making him so sympathetic.
 * An episode of MacGyver gave us a variation: Jack Dalton's mother gave him up for adoption to protect him from a mobster that was targeting her.
 * The episode "Family" on Cold Case
 * And the episodes "The Thin Blue Line" and "Into The Blue" reveal that Lily's dad abandoned her because.
 * In season 4 of Desperate Housewives, Lynette's stepfather shows up and tells her that the reason he left her family when she was a kid was because he's gay. Lynette's mother never told her because she was embarrassed about it.
 * Subverted in Season 2 of Heroes with Maury Parkman. After Matt tracks his father down, Maury hugs him and pretends to be sorry he left. However, Maury then uses his telepathic powers to trick Matt and Nathan into fighting each other.
 * Unsubverted during Season 3 when Maury performs a Heel Face Turn and works for Arthur Petrelli in exchange for his son's safety.
 * Averted in The Movie of Black Hole High when  tries to pull this on Josie.
 * Used in season three of Gossip Girl when mother shows up. Serena desperately wants to believe that her reason for leaving would play into this trope, since that would make Serena feel less horrid about having been abandoned by her own father.  crushes Serena's hopes and fantasies however by simply explaining "I didn't want to have a kid and I never regretted giving my child up."
 * Prison Break:
 * Married With Children: Seven's folks stick the Bundys with the kid, but for a good reason: They felt Al/Peggy would be better parents. Of course, he ended up on the side of a milk carton, so...
 * Married With Children: Seven's folks stick the Bundys with the kid, but for a good reason: They felt Al/Peggy would be better parents. Of course, he ended up on the side of a milk carton, so...

Music
"And he said, "Son, this world is rough/and if a man's gonna make it, he's gotta be tough/and I knew I wouldn't be there to help you along...""
 * In the Johnny Cash song A Boy Named Sue, the dad doesn't explicitly mention just why he left at all. He does, however, justify naming his son Sue:

Theater

 * Inverted in Annie: optimist heroine Annie assumes that her parents abandoned her for a very good reason and they will one day be reunited. Unfortunately,.
 * In the movie version of the musical, her parents did intend to return for her, but.

Videogames

 * In Jade Cocoon, Ricketz leaves his family and abandons his position as Cocoon Master of his village, because staying on would cause his wife to eventually die of a magically-induced cancerous disease, as the wives of all Cocoon Masters are women of the Nagi tribe who have a sacred duty to purify the demon-capturing cocoons their husbands inevitably accumulate in their role as magical protectors of their villages.
 * In Growlanser III, one of your party members had a father who disappeared one day; being half human and half Featherian, this lead to some Fantastic Racism among her relatives. (You eventually learn that the Big Bad killed him.)
 * Subverted in Disgaea 2 with Adell's parents. They left to defeat fake Overlord Zenon and failed. The subversion is in how they intended to return (assuming they won).
 * James in Fallout 3 had what he thought was a pretty good reason for abandoning the main character. However, it turns out he made a grave miscalculation: his disappearance sends the Vault into anarchy and gets his son/daughter marked for death by the Overseer. Of course, James makes a fairly impressive series of well-meaning miscalculations as the game goes on...
 * Final Fantasy X has Jecht, who spends most of the game a distant and apparently horribly abusive father to Tidus, who's reasonably pissed off that his father abandoned him and his mother. Turns out that . Since Tidus is, at the time, in a similar situation...
 * In Arc the Lad, Arc's father had a good reason to leave his wife and son for more than ten years . But, because Arc the Lad is... well, Arc The Lad,
 * In Trace Memory, Ashley's father left her with her aunt to pursue research on memory to find out about his wife's death.
 * Final Fantasy Crystal Chronicles Echoes of Time has an unusual case, in that they actually DIDN'T have a good reason, as far as we know. However it's pointed out multiple times that, had you not been abandoned, it would certainly mean The End of the World as We Know It.
 * Pretty much all the Earthbound/Mother games where your father is only seen at the other end of the phone providing you with money and gifts the entire adventure.
 * Final Fantasy Legend II opens with a scene where your father is last seen leaving through your bedroom window. Throughout the game, you wind up bumping into him repeatedly, finding out he's trying to save the universe just like you are. (And you try to convince him to come home more often.)
 * In Xenogears, Jessie claims to have a justifiable reason for abandoning his wife and children. In the game itself, the trope is subverted, as the explanation is not very thorough and the player is left with the impression that he's making excuses. After reading the explanation given in Perfect Works, though, it becomes clear that he had to leave in order to protect them and the trope is played straight.
 * In Pokémon Ruby and Sapphire/Emerald, the player's dad seems to live in his gym (he never comes out, does he?)
 * And don't forget Palmer, the Tower Tycoon from Pokémon Diamond and Pearl/Platinum. He is the rival's father and while he claims to remember you as his son's friend, he is never once seen outside of Battle Tower.
 * Tales of Symphonia has a couple.
 * Genis and Raine got abandoned because
 * Mass Effect 2 gives us Thane Krios who left his son Kolyat, Thane didn't want Kolyat to be influenced by his fathers job as an assassin, either by becoming one himself or being connected to him for his enemies to find.
 * In Quest for Glory IV, the Burgomeister's grandfather disappeared shortly before he was to marry the Burgomeister's grandmother, leaving her alone and pregnant. This resulted in the child and grandchild becoming rather bitter individuals. When playing as a paladin, you end up finding the grandfather's sword in a wraith's barrow, proving that his abandonment was not intentional - Piotyr had been killed before the wedding.
 * Legend of Dragoon. One would think that being possessed by the spirit of a near-12,000 year old megalomaniacal Wingly dictator and forced to set off a series of events that would lead to The End of the World as We Know It is a good reason for Parental Abandonment.
 * In Baldur's Gate 2 Cernd left his wife and unborn son to pursue his calling as a druid. He thinks his commitment to maintaining the balance of nature is a good reason for abandoning his family. Nobody else does. Even the evil wizard who is about to sacrifice the baby to a lich calls him out on it, asking if Cernd even knows the kid's name. To be fair, he didn't know his wife was pregnant at the time.
 * In Baldur's Gate 2 Cernd left his wife and unborn son to pursue his calling as a druid. He thinks his commitment to maintaining the balance of nature is a good reason for abandoning his family.

Visual Novels

 * In the backstory of Fate/stay night, had very good reasons for abandoning his Ilya. It's also not completely his choice:  It's not completely clear how much Ilya knows about his motivations - the Ilya path which would have focused on her was cut out of the final game, but she's still a lot less naive than she appears - but she angrily spent the ten years after he left plotting revenge.
 * This is only true in Fate, though. In HF, she doesn't make any attempt to (once she meets him properly),.
 * In Ever 17, had a good reason for abandoning her son and daughter: if she didn't, they'd be captured and researched upon in the hopes of finding a way to immortality, or at the very least would never be able to attend school or have friends due to constantly being on the run. It didn't really work out, but they did get more normal lives out of it. Oddly enough, she's the only one who really has a problem over it. The kids don't care in the slightest.
 * Their father also had a good reason, namely

Webcomics

 * Gunnerkrigg Court has an unusual variation, where someone else makes this excuse on the Disappeared Dad's behalf: No one besides Anthony Carver knows why he disappeared, but his daughter Antimony says that he "must have his reasons".
 * Except in the last panel of the same comic, she says "Perhaps I did something to displease him... or he wants nothing more to do with me." Both of which are definitely not valid excuses for basically orphaning your only daughter, soon after her mother died in a hospital.
 * Chapter 31 reveals that Not only that, but EVERY adult near Annie knew it would happen,  Also, Coyote reveals that  Coupled with his wife's death and his inability to save her, it's a bit more understandable why Anthony left.
 * In the webcomic Bizarre Uprising, Mitsu's father (secretly a vampire) abandons him and his mother when he was young. He did this beause He's the vampire Messiah and if the other vamps found out he was still alive, they'd try and drag him back, almost certainly killing Mistu and Biana in the process. He stayed in Mitsu's life as "The Pig", the school mascot, turned Mitsu's mentor in the ways of vampireness.
 * In Drowtales, Ariel comes to see her mother Quain'tana as this. She is quite aloof towards her children, leaving them for months or even years at a time at boarding schools or under the care of a slave or older sibling. Quil'yate explains to Ariel that this is not because the drow are evil, but because the clan believes that it is best for young nobles to learn to prove themselves, so that they can be strong leaders. This however should be taken with a grain of salt, since it also turns out that
 * Averted in Order of the Stick, where Eugene chooses not to follow a credible lead on Xykon, whom he's sworn to destroy, because doing so would most likely mean abandoning his family and dying at best, and having Xykon hunt them down for revenge at worst. He did, however, continue to be a neglectful Jerkass to his oldest son, and specifically claimed that he would have abandoned the family for his quest if given a chance.
 * In the Paradise setting, in which people get turned into anthropomorphic animals, this is addressed. In the early days, a man gets turned into a polar bear, but doesn't realize it's happened to others (Since he lives out in the frozen boonies of Canada) and tries to live a normal life... until while on a Seal Hunting trip ends up mauling a seal with his bear hands, at which point he becomes terrified of what he'd become and runs out into the frozen tundra to live as the beast he had become, leaving his wife and two sons behind. Years later one of his sons changed into a wolf, realized what happened, and went looking for him.

Web Original

 * In The Gamers Alliance, when Omaroch is reunited with his son Refan, he explains to him why he has been absent for so many years and wasn't around to save Refan's mother from death. He had in fact been kidnapped and imprisoned by demons and was thus unable to help his family when they needed him the most. Although he claims that he managed to flee from demons, the truth ends up being much more horrific: he was actually tortured and brainwashed to become a servant of the dark god Mardük and was ordered to return to the world of mortals to make sure his sons would fulfill an ancient prophecy which would result in Mardük's resurrection and a full-scale demon invasion. He eventually breaks free from the god's taint but at that point it's too late because his actions end up causing the Cataclysm as well as turning his son into a bitter person. He does his best trying to set things straight and regain his sons' trust.

Western Animation

 * Homer's mother Mona on The Simpsons. As it turns out, she was quite surprised when she found out that Homer believed her to be dead. The misunderstanding came up because (1) Grandpa Simpson was unwilling to reveal to young Homer that his mother was a criminal (she rolled her eyes at this reason), and (2) Homer's mistreatment of his mail carrier prevented any of her care packages from reaching him until he specifically asked about them. It's what happens when you don't tip them.
 * Also, we're led to believe Nelson's father abandoned him. Turns out his peanut allergy caused circus dwellers to kidnap him and use him as an attraction. Thanks to Simpsons' negative continuity, he is never refered again.
 * On Futurama, Leela grew up thinking she was a one-eyed alien, when in reality she was an unusually normal-looking human mutant. Realizing she could pass for "normal," her parents had abandoned her at an Orphanarium when she was a baby with a note in an alien language, allowing her to live on the surface rather than as a second-class citizen in the sewers. When they reunite years later and this is revealed it's quite the Tear Jerker.
 * They didn't actually abandon her, the ending montage showed that they cared for and watched over her from the shadows.
 * Avatar: The Last Airbender has a mild version of this; Hakoda hasn't been gone all that long, and explained his reasons to his kids first, but Katara at least still felt abandoned. She even says that she knew and understood Hakoda did what he had to do, but she couldn't help feeling like crap for not having him there when she needed him the most. They make up at the end of the episode, though.
 * Also, the reason why Princess Ursa is Zuko and Azula's Missing Mom?  Or so we think. It is probably what happened, but ones who reveal this information are Azula and Ozai, who are... not the most trustworthy of people.
 * Supposedly Ursa was meant to come back sometime during the series finale, but the Avatar team didn't want to have to waste a perfectly good plot by squeezing her in. This is probably the biggest unresolved plot thread.
 * In We Are the Strange, Rain had his Robot servant take his son to be raised in the Forest because
