Then the Lord said to Cain, "Where is Abel your brother?" He said, "I do not know; am I my brother’s keeper?"Sometimes Sibling Rivalry can get a little… intense. Maybe one who Missed the Call gets overly jealous that the other has become The Chosen One, maybe grand powers or knighthood run in the family and one just happens to have been tempted to The Dark Side, maybe one of them betrayed their master or father and the other has to stop him, or maybe it's just Because Destiny Says So, dammit. Whatever the case may be, now one's the hero and one's the villain, and they must do battle. Commence the angst. For whatever reason, the older sibling is almost always the villainous one. Probably because being younger and less experienced makes the younger sibling the underdog, whom we are supposed to root for. And because the Aloof Big Brother always looks eviler. The major exception is the case of The Evil Prince, who is usually the younger of two princes, and who will do anything to make sure he succeeds their father instead of his brother (or in the case of the prince being the king's brother, to take the throne for himself directly). It's not always siblings — Childhood Friends get to experience all the same woes from beating up someone they grew up with — but there's a certain poetry when they're actually related. Note that they are traditionally always of the same sex: brothers or sisters (though there are exceptions). In cases where the Cain turns out to be The Un-Favourite, he's likely to be viewed from a more sympathetic angle. Of course, this would partially also depend on the sibling's attitude in all this. Sometimes the siblings will become The Only One Allowed to Defeat You, or realize they're Not So Different. If the hero isn't aware of the relation until late in the series, it's also a Luke, I Am Your Father. We Used to Be Friends and Evil Former Friend also counts if the siblings in question were former friends with each other. Compare Oedipus Complex. Contrast Sibling Team. Also contrast Bash Brothers, where the two people (who may or may not be brothers) beat up other people instead of each other. When Cain is gunning for mom and dad instead of Abel see Antagonistic Offspring. The trope title, of course, comes from the biblical story of the first siblings to exist. See also Name of Cain. When There Is Another, compare Cain and Abel and Seth. May overlap with Big Brother Bully if said bully is truly malignant. If such a situation turns lethal, it's Sibling Murder. If not a Good vs. Evil situation, see Sibling Rivalry. Not to be confused with the two recurring Character Archetypes found in the Fire Emblem series.
And the Lord said, "What have you done? The voice of your brothers blood is crying to me from the ground."

Anime & Manga
- In Akagami no Shirayukihime the current head of the Bergatt family is a viscous cruel man who is controlling his younger brothers out of fear. By the time any of the main cast learn Touka's true plot to assassinate Zen Wisteria he's decided to kill his brothers for daring to defy him and his brothers have decided to kill him because he's gone too far and they feel it's necessary, and the right thing to do.
- Servamp is an aversion of the bad big bro stereotype. The Cain in this case, Tsubaki, is actually the youngest brother from all the Servamps, and he's the Cain to his seven elder siblings.
- Attack on Titan: Zeke, aka the Beast Titan, turns out to be Eren Yeagar's older half-brother. However, nobody really knows which side he's on and he may be working for himself. He seems to be trying to save his brother from certain doom which their father is responsible for, although it's yet to be seen if Eren actually wants his help. They appear to have been in contact recently, however.
- In Area 88, the Asran civil war was started by two royal brothers—King Zak and Prince Abdael—with different visions for the future of their country. Tensions erupted years before the conflict, when their father chose the younger brother (Zak) to succeed him.
- In Axis Powers Hetalia, the characters of China and Japan enact this trope in their Back Story, with China as the Abel (despite being the elder) and Japan as the Cain. Japan was raised by China as his younger brother, yet never really considered himself his brother, and in the end he injures China with his katana and abandons him. Even when they're shown later to be in more civil terms, the bad blood is not exactly gone.
- The character of "Korea" represents only South Korea, due to the obvious Real Life issues surrounding the two countries in the peninsula. When fanworkers create an Original Character representing North Korea (sometimes male, sometimes female), they and South Korea end up recreating this trope as well.
- Due to the nature of the show, there's really a lot of this going on: America and England have this dynamic in America's flashback about his revolution (which England is still upset about), too, and anytime fanwork depicts a conflict between two related nations it becomes this very quickly.
- Fanon characters 2P!America and 2P!Canada are generally depicted like this, too, with 2P!Canada as the Abel to 2P!America's Cain.
- In Betrayal Knows My Name, it turns out that Kanata, Yuki's childhood friend from the orphanage where he grew up, who was like an older brother to him, is actually Reiga, the Big Bad.
- In Blood+, a natural scientist finds Saya and Diva's mother's corpse and hatches the infants from their cocoons (it's complicated). As part of an experiment, he raises Saya as his own daughter and locks Diva in a tower to be a guinea pig. Saya is raised as a normal human girl; Diva is experimented on and denied anything more than a blanket and a meagre amount of food. Saya grows up seeing humans as equals; Diva grows up seeing humans as torturers and also food. One day Saya meets Diva and lets her out. The resulting bloodbath started a conflict between the two sisters that lasted for over a century.
- Blue Exorcist:
- The tragic aspect of this almost happens to Rin (Hot-Blooded Anti Anti Christ) and Yukio (genius exorcist and Rin's younger twin brother) when the former discovers he's the son of Satan and then learns that the latter knew it all along and now wants to kill him (they get better) but there are still hints that Yukio is more susceptible to the dark side.
- Secondary case with the other two sons of Satan, Mephisto Pheles (AKA Johann Faust V) and Amaimon: Mephisto is outgoing and clownish (similar to The Millennium Earl, complete with umbrella) while Amaimon seems to be quieter and darker.
- The Unno twins of Brave10 are this. Nanakuma knows he's The Unfavorite and that his parents only didn't kill him at birth because they weren't sure which twin would inherit the Water Crest eye. When it and the God's Jewel, go to the older twin Rokuro, he feels inferior, reinforced when his lord Nobuyuki is unhappy to see the "superior" Rokuro choose to serve Nobuyuki's brother instead. Eager to prove himself as a worthy page, Nanakuma is ready to kill Rokuro in a Duel to the Death in the tournament arc and take the God's Jewel for his own. By contrast, Rokuro doesn't really reciprocate or care...but would still try to kill him if ordered not to lose.
- Chrono Crusade uses this trope not once, not twice, but three times.
- Aion and Chrono, as they often seem to be even more than brothers… in the manga Aion and Chrono were close friends and described as "like brothers"—demons in the series are Bee People and don't exactly have the concept of family. Except Chrono and Aion were turned into demons when their (human) mother was pregnant with them—they're twins. Aion is rather obsessed with getting Chrono back on his side, although when he refuses Aion gleefully tortures him for it. The anime version makes the pair have a more distant relationship, but also implies that they're two sides of the same coin. (Not to mention giving the pair their fair share of Ho Yay.)
- Meanwhile, Rosette made a contract with Chrono in order to save her brother, Joshua, after he was kidnapped by Aion. It turns out that Joshua is radically devoted to Aion (partially because he's been given power that drives him mad), which causes the pair to fight… when Joshua remembers Rosette is his sister at all.
- Satella reveals early on that she's searching for her missing sister. Guess who also happens to be working for Aion? Her sister Florette, now called "Fiore". When this is revealed the pair naturally ends up fighting each other.
- Code Geass: Lelouch and Suzaku were childhood friends, reunited and fighting for each others' countries, not their own. Lelouch knows at first that Suzaku is a Britannian soldier, but he doesn't know how important he is to them. Similarly, Suzaku suspects that Lelouch is Zero from when he first meets Zero (when he says, "An old friend used to say that about me,"), but his suspicions are under about twenty layers of denial. When they finally do find out the truth, it's after a Wham Episode neither of them can recover from...
- There's also the fact that Lelouch is actually a prince of The Empire that he's rebelling against, and as such, has to fight several of his siblings. None of them (save Euphemia, who wanted to make peace instead of fighting) had as close of a relationship with Lelouch as Suzaku did, though. But Lelouch is able to use things he knows as their brother against them - such as Cornelia's obsession with Euphemia. Unfortunately, that goes both ways once he's dealing with Schneizel.
- In Corsair, Jean-Hughes blamed Canale for everything that went wrong with their family and tried to kill him several times as a child (thinking he succeeded). When he finds out Canale is, in fact, still alive he continues to plan to do him off. While Canale has a lot of blood on his hands at this point, Jean-Hughes is clearly the "evil" brother and in the end Canale kills him instead.
- In Cain Saga, Earl Cain is, ironically, the Abel to his psychopathic and illegitimate elder half-brother Jizabel.
- Heine is the Abel to Giovanni's Cain in Dogs: Bullets & Carnage, although they aren't blood brothers but were simply raised in the same research facility by the same Mad Scientist "mother".
- Goku and Raditz from Dragon Ball Z. Cooler, Freeza's Stronger Sibling, notes that they would have been this sooner or later if Goku hadn't beaten Freeza first.
- D.Gray-Man: MAJOR SPOILER ALERT!! You have been warned.
- Nea and Mana are revealed to be twin brothers and the result of the split of the original millenium earl. The trope is zigzagged here, Nea is firstly the Cain as he attempted to kill Mana to take his place, slaughtering all the other Noah but Road in the process. However in the final confrontation this is Mana, the Abel who eventually killed Nea turning the trope around. The trope becomes glaring when you realize that the second name of the woman who raised the twins is Eve and the name of the original Earl of Millennium who beget them if called Adam
- Agon and Unsui of Eyeshield 21 seem to be set up as this at first, with the younger sibling being blessed with unlimited talent and the elder having to suffer hellish training just to be half as skilled. However, while there's definitely some tension between them, the older brother ends up being more dutiful to the younger rather than hateful.
- Fairy Tail:
- Natsu and Zeref, once the revelation comes out. In a twist, however, Zeref is the one who has more brotherly feelings towards Natsu despite being the Cain while Natsu is the one who sees him as more of an enemy despite being the Abel. This is due to the fact that Zeref became the Cain in part because of the horrible things that happened to him in his quest to bring Natsu Back from the Dead, while Natsu doesn't remember his past with Zeref due to the method of his resurrection. There's also the little fact that Zeref has become an evil wizard bent on killing off humanity, which makes them automatically enemies, and Zeref wants Natsu to kill him to end his curse.
- Subverted by both Hoteye and Angel of the dark guild Oracion Seis, who are the older siblings of Wally Buchanan of the Tower of Heaven and Yukino Agria of Sabertooth. Hoteye (Richard) joined the guild originally because he wanted to find Wally and was obsessed with wealth because he thought it was the only way to reunite with him, while Angel (Sorano) originally became a slave because she protected Yukino and despite turning evil still loves her, while Yukino has nothing but good memories of her sister.
- Fist of the North Star: The villains, Raoh and Jagi, are the series's Cain to Kenshiro and Toki's Abel. Though Kenshiro and Jagi's relationship is more direct (with the former killing the latter instead of the other way around), Noble Demon Raoh subverts this. While he defeated Toki in combat, Raoh sheds enormous amounts of Tender Tears, knowing his condition due to radiation sickness. Raoh and Kenshiro also has their first and final battles. While the first fight between the two is seemingly played straight, the final one isn't. Raoh held his brother's face like a true big brother after his defeat.
- In the Fullmetal Alchemist anime, the homonculus Envy turns out to be the result of attempted resurrection of Hohenheim and Dante's son, making him Ed and Al's older (by a few hundred years) brother. This is foreshadowed repeatedly through the series, with much of Envy's actions being a result of his, well, Envy of Ed and Al for being their father's favourites, as well as a burning hatred for his father. Envy even ends up killing Ed (albeit temporarily) like the Trope Namer, for bonus points in this trope.
- Kagura and Kamui of Gintama, estranged siblings who would probably have gotten along were Kamui not such a jerkass (trying to kill your dad then disappearing for years is not the way to forge strong family bonds). As it is, Kagura considers all their bonds severed and Kamui seems to want little to do with her.
- Glass Fleet: Vetti and Cleo. Though they don't know they're related until the very end of the series, combining this with the Separated at Birth trope.
- In God Mars, the relationship of Takeru with his brother Ma, which fate would have it, pitted the two against each other in the war.
- Gundam has a lot of them:
- Gundam SEED gets Kira and Athrun, who're the childhood friends version. Unusual in that neither is really a villain, and both end up in a third faction after both sides they worked with turn out to be villainous. Though not before a climactic and nearly fatal final duel halfway through the series, naturally.
- Kyouji Kasshu and his little brother Domon from G Gundam… Or so we think.
- Ginias Sahalin from Mobile Suit Gundam: The 08th MS Team. We meet him as Aina's caring-but-aloof brother. Twelve episodes later we bid farewell an obsessive, murderous mad scientist who forces his once-beloved sister to pilot his giant mechanical monstrosity, tells her that "Love is an illusion', produced by your body's glands!", and then shoots her. (This is between blowing up/poisoning his allies, working his minions to death, and destroying perfectly good viewscreens.) She doesn't really object when her Main Character boyfriend tells her "Sorry, but I have to kill your brother now", even when she's not exactly happy either.
- Mobile Suit Gundam Unicorn: Alberto is The Half brother and Cain to Banagher and his Abel
- In the original Mobile Suit Gundam we have Kycilia and Gihren Zabi, a pair of cold-blooded Manipulative Bastards and social climbers who are perfectly willing to kill one another if it means ascending to control of the family. More like Cain and Cain really.
- Higurashi: When They Cry involves this with the twin Sonozaki sisters, Mion and Shion, as one of the two is the only one (besides those who already knew the whole story) who doesn't get infected with the Hate Plague, while the other, when infected, throws her conscience out the window even before she loses her mind and racks up the highest body count in the series besides the instigator herself. Yes, the elder is the "evil" one—the murderer was Shion pretending to be Mion most of the time, but because of a mix-up in their childhoods, the elder girl, originally named Mion, ended up living as Shion due to a Twin Switch, so Mion was pretending to be Shion pretending to be Mion.
- In Honoo no Alpen Rose we have the sibling version with the Courtot brothers. Older brother Jean-Paul is a Cold Sniper hitman Cain, younger brother Lundi is an Action Survivor Abel.
- As a result of Inuyasha claiming the sword Sesshoumaru's been pursuing for years, their Sibling Rivalry escalates into this trope for a while, mainly due to Sesshoumaru's belief that Inuyasha's claim proves he's The Un-Favourite he's always secretly feared he was. This is eventually resolved.
- Ginka and Kinka are from a youkai race where two heads (with associated identities and personalities) are born to a single body and one personality must kill the other (and devour the defeated head) before they reach adulthood because it's the only way their race can survive. Unfortunately for everyone, Ginka and Kinka have made it to adulthood, both alive, both still firmly attached to each other, and both still trying to kill the other. Their fight can lay entire villages to waste. It's so bad they even have to negotiate when they go to sleep and for how long just in case one takes advantage of the situation.
- Yukari and Kuroh in K - Yukari turned on their master/adoptive father. In the movie that takes place between seasons 1 and 2, he returns as a Green Clansman, and Kuroh, as a Silver Clansman, is his enemy. Played with in that Yukari really does love Kuroh and wants to see him grow and become stronger, and regrets that they have to be enemies. When Kuroh finally defeats him, Yukari's reaction is simply "... beautiful." Kuroh's refusal to kill Yukari after that is very heartwarming.
- Tsubasa and Souma Ohgami from Kannazuki no Miko, though Tsubasa isn't really a bad guy and undergoes a rather spectacular Heel–Face Turn late in the series. What's more, technically, they are both Necks of Orochi, only that Souma has a good reason to fight against his "heritage".
- Belphegor and Rasiel from Katekyō Hitman Reborn!, possibly subverted in the fact that Rasiel isn't dead.
- Kazuya and Kyoshiro from Shattered Angels. No, Kazuya doesn't commit any redeeming acts like Tsubasa.
- Subaru and the Numbers Cyborg Nove in Magical Girl Lyrical Nanoha StrikerS, a case where the good one is the older sibling by virtue of being an earlier Quint clone. Of course, this being Nanoha, this stops being the case by the end of the season.
- Mawaru-Penguindrum: Kanba is the Cain to Shouma's Abel, largely because Kanba is in love with Himari, their (un)related sister and believes he has an obligation to protect her but Shouma saved her when she was younger (and he also saved Kanba when they met), and also disagrees about how Kanba has become more and more embittered, desperate and extreme in his methods in order to save Himari while Shouma is much more honourable and still believes things can be done without such extremes. It leads to QUITE the showdown, in which both guys get into a fist fight, before the last episode sees them face off.
- There is also Masako who is an Abel herself to Kanba, as his twin sister who desperately wants him to come back home after he made a deal with their Disappeared Dad to protect Masako and their little brother Mario from danger.
- Kanba in general is portrayed as a much more sympathetic version of Cain in general, as his reasons to be in such a position are less about his own benefit and more about genuinely but VERY misguidedly wishing to save Himari.
- In Mikado no Shihō, even though Shiki is older, he is the Abel to Rinshō's Cain.
- Johan Liebert and Nina Fortner from Monster.
- Tiger (older) and Gray Wolf (younger) in Monster Rancher. The roles are inverted with Tiger being the Abel to Gray Wolf's Cain. It's tragic because Tiger was a well-intentioned Aloof Big Brother who wanted to toughen his brother up. Unfortunately, this only fueled Gray Wolf's inferiority complex. And once Moo captures Gray Wolf, he magnifies these insecurities to the point Gray Wolf becomes a full-blown Green-Eyed Monster who wants to kill his own brother, much to Tiger's horror.
- Prince Kaito from Murder Princess is of The Evil Prince variety. Though the actual Princess Alita (his younger sister) doesn't really fight him, as she previously switched bodies with the Action Girl Falis who handles the fighting part for her.
- Michio Yuki from Osamu Tezuka's manga, MW, has this kind of relationship with his lookalike older brother, Tamanojo Kawamoto.
- Once, Sasuke Uchiha wanted nothing more than to be like his talented and caring older brother Itachi. Then, the latter seemingly snapped and wiped out the rest of the Uchiha clan, leaving Sasuke with nothing but his life, some harsh parting words, and a burning desire for vengeance against Itachi. After Itachi dies in the middle of fighting Sasuke, it's revealed that the former did it all as part of a deal to spare Sasuke; when Itachi is briefly resurrected, the two brothers manage to finally reconcile.
- To some degree, Hiashi and Hizashi Hyuga had this dynamic; because the former was born a few seconds first, he automatically became the heir to the clan, which Hizashi always strongly resented him for. Nonetheless, Hizashi still willingly sacrificed himself to save Hiashi's life.
- Hiashi's daughter Hinata and Hizashi's son Neji also have this dynamic despite technically being cousins (although Hinata thinks of Neji as a brother). Neji is quite bitter toward the younger Hinata, since she's the clan heiress despite his own much greater talent, and initially sees her as almost completely worthless until he loses to Naruto and rethinks his fatalist worldview. Hinata's relationship with her younger sister Hanabi is not this trope, as both sisters love each other very much despite their rivalry.
- It's later revealed that the conflict between the two founding clans of the Hidden Leaf Village was based on this trope. Essentially, the Uchiha and Senju clans are descended respectively from the elder and younger sons of the Sage of the Six Paths; after the Sage picked the younger to be his heir, the elder declared war on his brother, with their descendants continuing the fight despite no longer remembering the reason for it. On a side note, the two brothers are also the grandchildren of a woman who ate the forbidden fruit from the God Tree, like how the Trope Namers were the sons of Eve.
- One Piece:
- Marshall D. Teach and Thatch. On the crew of the great pirate Whitebeard, all of his crew mates are considered his adopted children; likewise, they consider him "father," and one-another brothers. Since Teach and Thatch were crew mates, the former killing the latter players this trope surprisingly well.
- The reason Trafalgar Law has it in for Doflamingo is because Doflamingo murdered his own younger brother Corazon, whom Law deeply admired. Ironically, Doflamingo had been grooming Law to take Corazon's place in his crew.
- Hana and Ageha from Papillon Hana To Chou: Hana is a popular city girl and a little manipulative while Ageha is plain country girl and walked all over. When Hana steals Ageha's potential love interest, Ageha is nearly Driven to Suicide. Their mom is a Well Done Daughter Gal to boot: Ageha was sent to the country because her constant crying aggravated her post-partum depression. As Ageha gains confidence she and her mom's relationship improves while Hana's behavior gets worse: Her latest scheme to ruin her sister's life caused Ageha's current boyfriend to break up with her, although they shouldn't have been together in the first place(eh, if he couldn't tell them apart he's probably not worth it anyway)
- Princess Resurrection. All the royal siblings virtually are fighting to the death for the throne except for the main character Hime who has no interest in it.
- Pops up in season 2 of Princess Tutu, when Mytho becomes tainted with Raven's blood and performs a Face–Heel Turn. His best friend Fakir is constantly forced to fight against him, even though they were practically raised as brothers.
- It's hard to avoid in Rozen Maiden, where There Can Be Only One of seven sisters that survives (unless that cryptic statement at the end of season two has anything to say about it). Suigintou and Shinku in particular have exactly this relationship, although who is the betrayer and who is the good underdog switches around in different points of the timeline.
- The main conflict in Saber Marionette R is the prince of Romana Star-Face wanting to kill his little brother Junior, making Star-Face Cain and Junior Abel. Unlike the original Cain and Abel, it's Star-Face the one who dies, though not on Junior's hands.
- In Saint Seiya, Kanon (younger) and Saga (older). In the beginning, Kanon was evil and Saga was good, but Saga went insane for having a Superpowered Evil Side (coms with being the *Gemini* Saint, of all Gold Saints) and turned evil. Kanon *knew* his brother would become evil and used it to his advantage, staging an epic Gambit Roulette that covers several arcs of the story (two in the manga, three in the anime), where Saga was the first Big Bad and Kanon was the Man Behind the Man from both him and his boss. However, later Kanon pulls a Heel–Face Turn and joins the good guys, while Saga turns evil… apparently..
- Phenix Ikki (older) and Andromeda Shun (younger) were at first like this. Still, Ikki pulls a Heel–Face Turn early in the story and joins the Five-Man Band.
- Apparently Kurumada loves this trope very much because now in Next Dimension we get the real Abel and Cain, and once again Cain is the older one.
- The filler Asgard saga adds the Mizar Saints, Syd (Abel) and Bud (Cain), who were Separated at Birth twins. It ends in massive tragedy - and with both of them dead, right after they finally sort-of made peace.
- Saint Seiya: The Lost Canvas is rife with this.
- Sasha and Alone, a brother and a sister who are actually reincarnations of Athena and Hades and are in war against each other for the fate of humans. Sasha is Abel and Alone is Cain.
- Tenma and Alone play the childhood friends version of this, with Tenma as the Abel and Alone as the Cain.
- Yuzuriha and her younger brother Tokusa, who awakened as a Specter after killing their parents.
- Another childhood friends version comes into play with Aquarius Degel and Sea Dragon Unity, who decided it would be cool to revive Poseidon. Unity eventually has a Heel Realization, but Pandora wrecks everything, and Degel has to freeze himself along with the entire city of Atlantis to prevent Poseidon's awakening.
- As usual, the Gemini Saints end up playing this trope. It's subverted in that, while Defteros was treated badly in the Sanctuary, it was Aspros who became the Evil Twin, due to a growing fear of Defteros' determination to become his brother's equal. He tried to use Defteros as a pawn to kill the Pope (no, not that Pope), and wound up getting killed by Defteros. When he was revived by Alone, he and Defteros had their face-off, and Defteros made a Heroic Sacrifice to restore Aspros' sanity. When Aspros realized what had happened…
- Teru and Saki were once close while growing up, but an incident during their childhood, the full details of which have not been revealed yet, resulted in their parents separating, each taking custody of one of their daughters, and Teru hating Saki enough to stop talking with her and even deny having a sister. Saki's goal in the series is to face Teru in mahjong and somehow reconcile with her.
- Shoukoku no Altair: Egomaniac Sultan Balaban is the Cain and his kind-hearted younger brother Prince Beyazit is the Abel, however in a twist Beyazit ends up dethroning and killing Balaban to end his tyranny.
- Sisters Rally and Rosa Cheyenne fall into this in Silent Möbius. In this case, the elder sister (Rally) is the good one.
- Soul Eater has Asura (Cain) and Death the Kid (Abel). As this is revealed to Kid only in the finale, he barely has time to deal with this fact before his 'older brother' is imprisoned once more. Up until this point he had thought Asura was merely his father's adversary. Recognising that a fight between Anthropomorphic Personifications could potentially cause Metaphysical Annihilation if either invokes their Reality Warper abilities Kid rejects his brother's We Can Rule Together offer and decides to Take a Third Option by siding with humanity.
- Also had Masumune (Cain) and Tsubaki (Abel).
- The sisters Harulu and Karala from Space Runaway Ideon are an archetypal example: the older, more socially awkward but decisive Harulu grows jealous of the dreamy, honest but romantically successful Karala and shoots her to death (during the Kill 'em All), only realizing her true reasons afterwards.
- In Spiral, Ayumu is struggling with the shadow of his elder brother Kiyotaka, although they don't actually fight until the end of the manga. Also Kanone and the other Blade Children, as they were childhood friends (and, again only in the manga, actually also all half-siblings.
- Str.A.In.: Strategic Armored Infantry: Sara is happy, bright, and has an enormous case of Big Brother Worship. Then Ralph, said big brother, turns out to be a psycho that wants to kill all humans, starting with the entire population of Sara's school. It all goes downhill from there.
- Tekkaman Blade. The English dub (Teknoman) actually names one of the brothers Cain, and Tekkaman Blade II includes the biblical Cain and Abel story in its title crawl. This is also slightly reversed: the elder brother (Takaya/Blade aka Tekkaman Blade) is good, the younger brother (Shinya/Cain aka Evil/Sabre) is evil.
- It should also be mentioned that, in the original, the Big Bad, Kengo/Conrad aka Tekkaman Omega, was also Blade and Evil's older brother. And their youngest sister, Miyuki/Shara aka Tekkaman Rapier, is the gentle Sacrificial Lamb who chooses to die through Heroic Sacrifice rather than through her fatal illness.
- In Transformers: Robots in Disguise, Optimus Prime's brother Ultra Magnus shows up on Earth with a serious grudge over the Matrix of Leadership having gone to Optimus instead of him, and quite a bit of firepower:
Optimus: He's grown a little bitter over the years.
Side Burn: Bitter? Bitter is not sending you postcards, but this wacko... He knocked you off a cliff!
- Trigun: Vash and Knives.
- These two are notably twins with no idea who's older, and the Japanese word they use for their relationship is the incredibly vague "brethren" but because of the conventions of this trope many fans tend to treat Knives as the elder brother.
- Given the vague Christian references that get tossed in, the anime scene that confuses who's supposed to be the Cain here was probably intentional: shortly after Knives kills pretty much everyone else, little Vash stands over him at night with a big rock trying to work up the nerve to bash his sleeping brains out. He doesn't manage it.
- Trinity Blood: The battling twins at the center of the story are literally named, "Cain and Abel." Care to guess which of these is the villain and which is the hero? (And to REALLY beat the biblical reference over your head, their little Crusnik "sister" is, of course, named Seth. And their common maternal figure is named Lilith.) Subverted in that it was Abel who first went after Cain because he murdered Lilith.
- You've got a Big, Screwed-Up Family trapped in a mansion possibly murdering each other… Given the context, it would've been astounding if Umineko: When They Cry could have gone without invoking this trope. It's been invoked at a bare minimum, three times.
- Folken Lacour de Fanel (Cain) and Van Slanzar de Fanel (Abel) from The Vision of Escaflowne, though Folken goes for a Heel–Face Turn mid-series. After all he had done, though, it still takes a lot for Van to forgive him. This is a slight variation in that there's nothing personal about it from Folken's point of view: they just happened to wind up on different sides of an ideological dispute. It's played straighter in The Movie, which casts Folken as a straight-up Green-Eyed Monster Cain over not being named heir.
- Ditto with an older example — Voltes V: Prince Heinel and Kenichi Go. And unlike in most cases of this trope, they have much in common, personality-wise.
- In Witch Hunter, the rivalry between the three princes of the Bairong Empire gets very intense, even though one of them doesn't actually want the throne… one guess what happens. In a heartbreaking twist, the only actual fatality so far was a Mercy Kill done by one brother to free the other from a Grand Theft Me inflicted on him by their father. The third sibling is furious at the killer brother for doing this, while the killer hates his surviving sibling for allowing this horrible situation to happen in the first place.
- Kamui and Fuuma, in another friendship variety.
- The sisters Hinoto and Kanoe count as well. The younger one, Kanoe, is the evil one though.
- In Yu-Gi-Oh! GX, Manjyome hated both his brothers. They originally had a plan to Take Over the World via business, politics, and Duel Monsters, with him providing the last. However, Manjyome really never had any say in the matter. Eventually, he realized he was just a pawn to them, and quit. He got his revenge against them in spades; when they attempted to take over Duel Academy on their own, they demanded a duel from him with him using only monsters that had Attack Points of 500 or less. Manjyome took this one step further, using only monsters with zero Attack Points, and still won, humiliating them beyond belief.
- another example from GX is Shou Marufuji (Syrus Truesdale) and his older brother, Ryo (Zane). While Ryo is more cold and antagonistic, Shou is the absolutely sweet and adorkable best friend of the series' main character, Judai (Jaden). While Ryo does actually care about his brother on some level and can be very protective of him in his own messed up way, he also dislikes his younger brother, despite the fact that Ryo practically worships him. Later on, after being corrupted in season two, attempts to pretty much flat out KILL Shou in a duel. Even though he gets better, he becomes totally emotionally distant from Shou and the two pretty much never acknowlege each other. It turns out that Ryo has a fatal heart condition and, when he dies during a duel later on, he basically tells Judai that he's Shou's real brother and needs to take care of him. (In the dub, at least) Ryo does eventually come back to life near the end of the series, but his disease has progressed to the point where he's in a near-constant unconscious state and, on the rare occasions that he is awake, he's more or less a wheel-chair bound vegetable in need of round-the-clock medical care. By the end, Shou actually ends up taking a level in jerkass because he has grown bitter over having to be his disabled brother's caretaker and downright despises Ryo for his embarrassingly pathetic state. This is taken up to eleven in the manga where, despite still being willing to look out for Shou and save him when necessary, Ryo downright HATES his younger brother and makes no secret of it. In fact, despite the fact that Ryo is a beloved and famous duelist (and the top student in all of the duel academy's history), Shou never tells anyone that he is Ryo's little brother until he is nearly expelled from the academy due to a misunderstanding and his friends accidentally find out. In fact,in the manga, Ryo was very angry at Shou for getting accepted into the academy and despised the fact that his brother wanted to follow in his footsteps. In a flashback, after finding out about Ryo's acceptance, Ryo angrily states to Shou that he (Shou) isn't any brother of his and, before leaving, tells him that his kindness and innocence will destroy him one day. It's no wonder that Shou becomes attached to judai and reveres him as a big-brother-figure, despite the fact that they are the same age.
- A far worse example in the franchise was Lotten, the main antagonist of the Crashtown arc in Yu-Gi-Oh! 5D's, who double-crossed his brother Malcolm to take over Crashtown. Of course, Malcolm was a crook himself, but Lotten was likely the only person he trusted. Bad idea; this was truly a case of No Honor Among Thieves.
- In the original Yu-Gi-Oh!, Rishid (Odion) and Marik Ishtar were nearly this as children. When Marik was bitten by a poisonous snake as a toddler while Rishid was playing with him, their father beat Rishid up badly and threatened to kill him if Marik died. Rishid has what could quite possibly be a mentally breakdown and blames Marik for their father (who is only Rishid's adoptive father) abusing and hating him (and possibly also for the death of their mother, who died giving birth to Marik) and enters his younger brother's room with a dagger, intending to kill Marik while he is unconscious. Before he is able to do it, however, Marik begins to wake up and, not realizing what Rishid is about to do, calls out for his big brother. Rishid is shocked into hesitating and asks Marik what he just called him. Marik says that he had always thought of Rishid as his big brother, which causes Rishid to drop his weapon in shock. Rishid warns Marik to not say such things because it would make their father angry, but little Marik reaches out to hold Rishid's hand and tells him that it doesn't matter what their father would do to him because he would always love Rishid and think of him as his big brother. Rishid realizes that he just almost killed the only person who cared about him and bursts into tears as he hugs his little brother. It's implied that part of the reason that Rishid is so loyal to his little brother, despite his immoral actions, is because he feels regret and shame over attempting to kill him. Either way, it's pretty much outright stated that Rishid stayed with Marik because he loved his younger brother and felt like he owed him his loyalty because Marik choose to make him his brother, so they successfully subvert this trope.
- Even though the English dub cuts out the murder attempt above, Which only occurs in the Japanese anime and the manga,the trope still appears and is also subverted.In it, Odion (Rishid) more or less raised Marik and did genuinely love his younger brother, but was also jealous of the fact that Marik was the biological child of their parents and held a grudge against him for that and their father's mistreatment of Odion. The snakebite scene still happens in the English version but, instead of trying to murder him, a noticeably angry Odion sits next to Marik's bed and waits for him to wake up. When Marik wakes up, he apologizes for being the reason that Odion gets beaten by their father and, like in the original, says that he loves him as his big brother, which causes Odion to let go of his hatred towards Marik.
- Zatch Bell!: Zatch and Zeno (Gash and Zeon in the original). Zeno hates Zatch because the latter received the powerful "Bao" spells. In the manga, they end up reconciling, but Zeno hates Zatch to the end in the anime.
- Aquaman frequently faces off against his evil brother Orm, the Ocean Master.
- In the New 52, it's only somewhat of an example. Orm isn't portrayed as outright evil, and the two actually get along pretty well, but once Orm decided to attack the surface, it became this. The reboot also made it a case of We Used to Be Friends, where the two are portrayed as having been very close as teenagers.
- Arawn and his brothers have a extremely murderous rivalry caused primarily by the machinations of the Cauldron of Blood, promising ultimate power to all of them simultaneously if they backstab each other. Its so intense that its hard to figure out which of the brothers were the good and evil ones. The biggest one driving the series is between Arawn and his eldest brother Math, who becomes so insanely jealous of his possession of the Cauldron that he kidnaps Arawn's wife, forces her to marry him and carry his child, while he kills Arawn's own son. At the end, their beef is cut short when Math is killed by someone else, but after Arawn becomes an God of the Underworld, he makes sure that his brother is eternity tortured for his terrible crimes.
- Deadpool has Ellie & Warda. Half-sisters, who duel for the Deadpool name. Warda is the younger sister, but is the Cain. She says she hates Wade because of her inheritance and face, having inherited his scars. But later comments hint it was more. At one point, Warda punches Ellie and claims she had everything. She eventually delivers a fatal blow to her, unaware of Ellie's Healing Factor. As Wade grieves, Warda asks would he cry for her if she was killed instead. Ellie heals and returns to the fight -to Warda's anger. Wade breaks them up to reprimand Warda on the unnecessary war and she points at Ellie, telling him to lecture the family he wanted. Wade straightens her out by admitting that he didn't want any of them and that they all just happened.
- Pakrat the thief and his brother Rident Oly the intergalactic police officer in Atari Force.
- Batgirl Barbara Gordon and her brother James Jr.: In The Black Mirror, James attempted to murder Barbara by driving knives into the arteries in her legs and then pulling one out himself. He also set his sister up in 2012 story arc Death of the Family.
- Since his resurrection, Jason Todd has repeatedly attacked his adoptive brothers Dick Grayson and Tim Drake. It came to the point that in Battle for the Cowl he actually tried to kill them.
- Damian also has this toward Tim, reasoning that he would have to kill the then-current Robin to get Batman's respect. He's undergone some Character Development since then, but there still isn't much brotherly love between him and Tim and for some time he regularly sabotaged Tim's equipment in ways that would probably kill those without the type of training Tim has.
- In the New 52, Owlman is (supposedly) Thomas Wayne Jr., Bruce's brother.
- In one story in the Batman Black and White motion comics, one of Harvey Dent's many, many attempts to become sane again is ruined because his plastic surgeon fiance had a psychotic twin sister who was even crazier than Two-Face.
- Kalibak, son of Darkseid, is the adopted brother of Mister Miracle, the biological brother of Orion, and an enemy to them both.
- Gotham City Garage: Batman eliminates James Gordon and then attempts to blame his murder on Kara Gordon to get her sister Barbara to hate and hunt Kara down. It almost works until Harley Quinn of all people tells Barbara her little sister is innocent.
- Hawkeye and his older brother Trickshot. Trickshot even impersonated his brother during his time with the Dark Avengers, just to piss him off.
- Skaar and Hiro Kala, the twin sons of The Hulk. Hiro-Kala wanted to kill Skaar, and then himself, to finally destroy the Old Power they inherited from their mother, as he believed it would eventually destroy the universe. Main problem was that he was going to do this by crashing a Mars-size planet into Earth to destroy both worlds, in his words "sacrificing billions to save trillions."
- The Marvel versions of Hercules and Ares are bitter rivals throughout their comics histories. In The Incredible Hercules, Ares' primary reason for despising Hercules is said to be his anger that mortals favoured Hercules over him, despite all the benefits (fame, power, empire) that war brings. But he overlooks the bad things of war (death, destruction, fear and often a heavy poverty)
- Judge Dredd and his brother, Rico. Dredd arrests Rico after he goes rogue. Twenty years later, Rico comes back for revenge and Dredd is forced to kill him.
- J'onn J'onnz, the Martian Manhunter, also had his share of troubles with his evil sibling Malefic, who was responsible for wiping out the entirety of their species, before J'onn tossed him into the sun.
- The Mighty Thor's archenemy is his adopted brother, Loki.
- Though it's never established if they're blood siblings or not, John Doe and Alfie O'Meagan from Nth Man: The Ultimate Ninja are same-age infants who were found and raised in the same orphanage. The series centers around John's efforts to stop Alfie from destroying the world.
- The Sandman and associated titles feature Dreaming versions of the original Cain and Abel. Abel is harmless, but Cain feels driven to repeatedly murder him. Furthermore, Cain won't stand for anyone else harming Abel. These versions of the characters are originally from DC's 70s horror titles. In said '70s titles, this is averted: they're a pair of Horror Hosts and quite chummy.
- In a less literal example, Desire has sworn to set the Kindly Ones on his/her brother Dream. In this case, Desire is the younger sibling.
- In the Sonic the Hedgehog comics, Lien-Da and her brother Kragok hated their half-sister Julie-Su due to their belief that their father liked her better. Kragok's dead these days, but the rivalry between Lien-Da and Julie-Su is still going strong — and it's not helped any by Lien-Da working for Eggman and Julie-Su being Knuckles' girlfriend.
- Lien-Da's actually been on both sides of this — she and Kragok were supposed to take over the Dark Legion together after killing their father, but Kragok set things up so that Lien-Da would be badly injured in the process, so he could cheat her out of the position.
- Going further back in Echidna history we have the twin brothers Dimitri and Edmund. Dimitri became infused with the power of eleven chaos emeralds following a Freak Lab Accident and tried to conquer the world. Edmund became the first Guardian and helped stop his brother's mad plans. That's just the beginning though as Edmund's descendants continued to pass on the mantle Guardians of Angel Island from parent to child, while Dimitri's descendents became the grandmasters of the Dark Legion. The two groups continue to battle each other to this very day turning a Cain and Abel scenario into a generations long blood feud.
- In a more metaphorical sense, there's Shard (the original and reformed Mecha Sonic rebuilt by the Secret Freedom Fighters) and the current Metal Sonic (still loyal to Eggman), who view each other as brothers, with Metal dedicated to destroying Shard.
- Spider-Man had Ben Reilly and Kaine, who were sort of brothers. They managed to work it out just in time for Ben to die.
- Kaine to Peter, too.
- During a brief Dork Age in the early 00's that was thankfully swept away by Infinite Crisis, Supergirl's father Zor-El hated his brother Jor, and sent Kara to Earth to kill Jor-El's infant son. Or he just didn't get on with his brother, and knew that Kal-El would "infect" Earth with evil spirits from the Phantom Zone. Or… look never mind, it's gone!
- In Crucible storyline, Roho attempted to murder his brother Tsavo and their parents.
- In Superman & Batman: Generations, Joel Kent, who was prenatally stripped of his Kryptonian superpowers by Gold Kryptonite exposure, was the Cain to his sister Kara's Abel, and in the same Biblical fashion ended up killing her when he got superpowers.
- Ulic and Cay Qel-Droma from Tales of the Jedi. There isn't any Sibling Rivalry until their master is killed and Ulic's attempt to become a Fake Defector results in him actually falling to the dark side and becoming the Sith Lord Exar Kun's Number Two. Nevertheless, Cay stubbornly believes that there's still good in his brother and tries to talk him back even after Ulic shoots his starfighter down. It doesn't work — Ulic kills him in a lightsaber duel. It's only after that when Ulic turns back out of remorse.
- This happens in Star Wars: Darth Vader with Morit betraying and pushing his sister Aiolin into a lava pit after she just saved his life, leaving it down to Vader himself of all people, who can very much relate, to pull her out and deliver a Mercy Kill.
- Anyone who's a fan of the Teen Titans cartoon knows that Starfire and her sister Blackfire are enemies… Their hatred for each other is a lot worse in the comics-and much more tragic, as it basically boils down to Blackfire being treated like a monster for something that happened on the day she was born and ultimately snapping and lashing out at her sister, one of the few who loved her but was given her birthright, until she started hating her back.
- Starfox and Thanos the Mad Titan. Their father forced them to agree to meet once every thousand years on peaceful terms in the hopes that they would eventually stop fighting altogether. So far they haven't.
- Tomoe and her Evil Counterpart Noriko from Usagi Yojimbo.
- Heroic trucker Ulysses Solomon Archer and his villainous brother the Highwayman from Marvel's shortlived toy tie-in comic U.S. 1 (and now officially part of the Marvel Universe).
- X-Men has a number of examples.
- Although they're both heroes, Cyclops and Havok frequently find themselves fighting against each other. Played straight between Cyclops and his other brother Vulcan, and played even more straight between Havok and Vulcan after the latter killed their father.
- Cable and his brother/clone Stryfe.
- Juggernaut Cain Marko and step-brother Charles Xavier.
- And in a metaphorical vein, Charles "Professor X" Xavier and Erik Magnus "Magneto" Lensherr — once the closest of friends, now on opposite sides of an ideological gulf on mutant/human relations.
- Also Professor X and Cassandra Nova, making him a triple header on this one.
- Banshee's cousin Black Tom is his brother in the Animated Adaptation.
- Wolverine and Sabretooth aren't brothers per se, but they were both products of the Weapon X project, and at one point it was (wrongly) believed Sabretooth was Wolverine's father. Chris Claremont has suggested that Sabertooth being Wolverine's father was the original plan.
- Emma Frost and her sisters, especially Adrienne whom she shot to death after Adrienne's actions led to Synch's death.
- There's also the human Graydon Creed and his mutant half-brother Kurt Wagner/Nightcrawler.
- Now Daken and X-23 can be added to the list, being the son and daughter of Wolverine. Daken is what Wolverine is trying to make sure X-23 does NOT end up like.
- Colossus and his (now currently deceased) brother Mikhael Rasputin. His relationship with his little sister Ilyana is only slightly better: Colossus is fiercely protective of her to the near detriment of every other aspect of his life, but she's a soulless demonic being (who nonetheless still loves Colossus as much as a soulless demonic being is capable of love). Eventually Ilyana forced Colossus to understand that she isn't the same innocent little sister he loved by manipulating him into suffering demonic possession as the new Juggernaut. When Colossus learned the truth, as well as the fact that Ilyana could have freed him at any time, he vows to kill her if they ever meet again. Ilyana is disturbingly pleased by this.
- In Avengers vs. X-Men, a badly injured Spider-Man manages to take down Piotr and Ilyana (both of whom have received insane power upgrades courtesy of the Phoenix Force) by tricking them into fighting one another.
- Psylocke and Captain Britain are twin superheroes, and their older brother Jamie Braddock is an insane reality-warper who flip-flops between loving sibling and insane supervillain. Eventually, Psylocke mind-controls Captain Britain into killing Jamie, in order to prevent his future self from destroying the multiverse. This rather sours their family relationship. In a less clear-cut example, at one point Psylocke killed Captain Britain's evil double from an alternate dimension, after he tried to rape her.
- In Fables, Snow White and Rose Red are descended from a line of powerful female magic users. Each generation of the family has been doomed to suffer from this because their power can only be inherited by one person. Many generations have tried to avert the trope by not fighting or not having children. So far, nothing's worked. Their mother tried to avert it in multiple ways, and failed each time. First by abstaining from the conflict, which failed when her remaining sister hunted her down anyway and she was forced to kill her in self-defense (though it's also implied she planned this all along). Then she resolved to die without bearing any children by remaining single for life, which failed when she fell in Love at First Sight with a man who wandered onto her home by complete accident (implied to be destiny at work to propagate the curse). Finally, she resolved to only have one child, which failed when she gave birth to the twins Snow and Rose. Learning all of this convinces Rose Red that a fight to the death with her sibling is inevitable. Since she's also convinced that she would lose in a fair fight, she also resolves to fight dirty…
- In "Fair, Brown, and Trembling", the two older sisters refuse to let their sister out of the house for fear she would marry before them. When she succeeds in marrying anyway, her oldest sister pushes her into the sea and takes her place.
- In "Finette Cendron", Finette's sisters force her to stay home from the ball.
- In "The Golden Bird", the hero's envious brothers have him Thrown Down a Well, and succeed in trapping him there.
- In "The Golden Mermaid", the envious older brothers beat their younger brother to death. The talking fox and golden mermaid revive him, and when he reaches court, the king banishes his older brothers.
- In "The Grateful Beasts", Ferko's brothers put out his eyes and break his legs. Then they slander him to the king to persuade him to set Ferko to Impossible Tasks until, finally, Ferko has wolves eat the king, his own brothers, and all the court.
- In "The Singing Bone", the younger brother is murdered by the envious older. His corpse rots, someone retrieves a bone from it and makes a flute, and the flute begins to sing of the murder. (Gustav Mahler adapted this tale for his early work Das klagende Lied.)
- In "Tsarevitch Ivan, the Fire Bird and the Gray Wolf", the envious older brothers kill the youngest, Prince Ivan. The talking wolf puts him back together and restores him to life, and they get word to his father, who turns his oldest sons into menial servants and make Ivan his heir.
- The same sort of thing happens in a large percentage of Russian fairy tales. Either there will be three brothers or three sisters. If there are three brothers, then the two oldest will be greedy and ambitious, and the youngest will be lazy, considered a fool, and usually named Ivan. The youngest brother will compete with his older brothers for something, and will always win through kindness and wisdom. If there are three sisters, the oldest two will be lazy, greedy, and vain, and the youngest will be the only one who ever does any work. The youngest will always get to marry the prince.
- In "The Unseen Bridegroom", Anima's sisters incite her to look at him at night, against his command, because they are envious.
- Way before A Triangle in the Stars begins, Bill was the Cain to Gabriel's Abel, though they initially got along excellently. The triangle just got fed up with how he was treated and how Gabe was so loved, and Gabriel in fact grew to be condescending towards his older brother. Instead of murder, the "Abel" was simply imprisoned. In the present, the school arc, the roles switch, for obviously different reasons. Interestingly, it's the Abel who kills the Cain.
- In Supergirl fanfic Hellsister Trilogy, Satan Girl is the Cain to her genetic template Supergirl's Abel. Neither of them like each other, but Kara is willing to accept her copy's existence as long as she doesn't harm others, whereas Satan Girl only wants to kill her.
Supergirl: You won't believe this, but I'm sorry. On my honor, I am. And if you will swear to stop this battle, I will help you search for your child. That is my promise.
Satan Girl: (sneering) Ohhhhh, don't you wish, Lightsister. I can find my child. After our war, I will find him. Or her. There is nothing left to us now, except the fight. You would not tolerate my existence, nor I yours. I am not capable of your empathy, of your petty virtue. You are not capable of my ruthlessness and power. Come, sister. Let us destroy each other.
- In Sonic the Hedgehog: Heroes of Mobius, Scourge the Hedgehog is Sonic's brother, and the Cain to his Abel, rather than his evil Alternate Self from a Mirror Universe.
- Kristoph and Klavier Gavin in Dirty Sympathy. While they have not hurt each other directly, there's a reason that Klavier is willing to frame his brother and he tells Apollo outright that he would have been in Apollo's position if he hadn't left. Notably, it's the Abel who struck first, by getting the Cain sent to jail before he could do anything.
- In Getting Back on Your Hooves, it's revealed that the Big Bad Checker Monarch who's trying to ruin Trixie's life is actually her big sister.
- Graduate Meeting Of Mutual Killing has brothers Reiji and Yukio Ohmoto. The former was the Assistant, while the latter was the Master. After a blunder Yukio did was quickly (and unsuccessfully) concealed via Twin Switch, Reiji got a spot in the Administrative Council of Hope's Peak. The influence and position of that spot gave Reiji what he needed to usurp Yukio's title and past, ending with Reiji as the Master and Yukio as the Asisstant.
- Bataar and Unegan in Hachin. Notably, it's actually the younger brother who's the Cain is this case.
- Inner Demons: Sweetie Belle and Scootaloo join Queen!Twilight, turning on Rarity and Rainbow Dash, their respective sister and sister-figure. And of course, Queen!Twilight herself ends up in this relationship with Shining Armor (though that's not her original plan). In all three cases, it's the younger one who's evil.
- Inuyasha and Sesshomaru, Kagoyasha and Inukyo in Inuyasha The Real World.
- Mufasa and Scar in The Lion King Adventures. Although neither of them kills the other.
- Hago and Bora, too. Hago slits his brother's throat after his first resurrection in The Return of Hago.
- Roll and Maylu are into this in Maylu's Revenge.
- Ace Ray (whose "crime" is complaining about Starfleet) and his sister Skye from My Brave Pony: Starfleet Magic.
- The Pony POV Series Dark World Series has a few examples. The backstory has two symbolic examples — Twilight Tragedy and Queen Cadence and Traitor Dash and Scootaloo — while the present has Angry Pie and Apple Pie as a more traditional blood relation (albeit distantly related).
- In the Shining Armor Arc, it eventually turns out that Makarov and Dima are half-brothers, with the former being the Cain.
- The former is also the Cain in a more symbolic relationship: when he starts warping reality to wipe out his enemies and make himself the grand hero of the world, he kills all the Changelings, including Chrysalis; both Makarov and Chrysalis were created by Pandora, making them siblings of sorts. Of course in this case Chrysalis is just as much of monster as her "brother".
- On that note, it's revealed that Chrysalis was created from the Shadow of Existence of the original Cadenza, while Cadence was made from her Light. This makes them "twin sisters", as Chrysalis puts it, making her the Cain to Cadence's Abel.
- Several examples in Superman story Superman of 2499: The Great Confrontation:
- Adam and Alan, the sons of the former Superman. Adam claims he doesn't hate his brother and is no threat to him, but he can't stand the fact that his father thought Alan would be a better Superman and Kath chose Alan over him. He holds a huge grudge.
- Klar -the former Superman- and his brother George. George also resented his older brother becoming Superman. Unlike Adam, he gets over it and makes amends with Klar.
- In Tales of the Emperasque, Corvus and Roboute are Abel to Fulgrim's Cain, and Leman and Lion go for each other's throats the first moment they can, although which one is Cain and which is Abel is complex and twisted case.
- In The Good The Bad And The Demon April O'Neil gets into this with her older sister, Nemissa due to the tragedy caused by the latter out of jealousy of the former hanging out with Hitomi Tono.
- Angel of the Bat features its main antagonist The Seraphim, who is the Cain to his older brother Joshua's Abel.
Films — Animation
- Zeus and Hades in Hercules. Hades jealously loathes his older brother, the benevolent Zeus, because the latter receives 100% Adoration Rating from all of the other gods while Everyone Hates Hades, combined with being stuck as lord of the Underworld. Bitter and envious of his brother's success, he decides to overthrow Zeus and kill baby Hercules so he can install himself as Top God and king of Olympus. He's widely despised on Olympus, and it's done to show how estranged and out-of-touch he is with them. They aren't happy at his appearance at Hercules's birthday, and even his lame pun is met with scowls. But when Zeus makes a similar lame joke about his workaholic nature, the entire pantheon bursts into laughter, while Hades storms out in anger.
- Mufasa and Scar in The Lion King, with the unfortunate addendum that Mufasa had no idea Scar was plotting against him until it was too late. A rare case where the younger brother is the evil one.
- In an interesting if debated adaptation choice, the film The Prince of Egypt made Moses the adopted brother of Rameses instead of his nephew, then played this trope to the hilt. The Biblical version had Moses found by Pharaoh's daughter, while The Prince of Egypt had his foster mother as Pharaoh's wife. Given marriage customs among Egyptian royalty of the time period, the same woman could easily be the daughter of Pharaoh X and the wife of his successor, Pharaoh Y. Thus, identifying her by her relationship to a Pharaoh depends on which Pharaoh is the point of reference.
- Avatar and Blackwolf in Ralph Bakshi's Wizards. And how.
"I'm glad you changed your name, you son of a bitch!"
Films — Live-Action
- Joey and Richie Cusack in A History of Violence.
- The vicious Red Queen in Tim Burton's Alice in Wonderland (2010) jealously loathes her younger sister, the benevolent White Queen, because the latter is adored by the populace (and, to judge by a throwaway line toward the end of the film, was the favorite of their parents).
- A deleted scene for Anchorman: The Legend of Ron Burgundy reveals that the eponymous character and Wes Mantooth are half-brothers.
Wes Mantooth: I hate you Ron Burgundy! I hate you.
- Angus and Henry Oldfield in Black Sheep (2007). Angus leaves Henry to be killed by man-eating sheep, and is later turned into a weresheep, at which point Henry does try to kill him as well.
- In The Hunger Games, if Gloss and Cashmere had survived to the end of the Quarter Quell, this would have been their fate. It's stated that the siblings share a close and loving relationship, so it's possible that they would've refused (like Katniss and Peeta) and preferred to die together instead of committing fratricide for a society that's already betrayed them. The Capitol citizens are at least somewhat horrified as well. Gloss and Cashmere are likely the first siblings to be pitted against each other in the same Games, and the pair visibly play this up for sympathy with hopes of the Quarter Quell being cancelled.
Caesar: You became everyone's brother and sister. I don't know how we're going to let you go.
Gloss: We aren't going by choice.
- In The Challenge, Toshiro Mifune plays a modern samurai master fighting his evil younger brother over ownership of "The Equals", a pair of sacred katana swords.
- In the backstory of The Curse of the Mummy's Tomb, Ra-Antef, the Mummy of the film, was a noble man who sought knowledge as the forthcoming Pharaoh and his brother Re was a scheming hedonist who was so jealous for his older brother's success that he organized him to be banished and later assassinated.
- Dead in Tombstone: Red and Guerrero are half-brothers. Red has always been jealous of Guerrero, despite the fact that Guerrero has always looked out for him. Red talks the rest of gang into betraying Guerrero and fires the first shot in the fusillade that kills him.
- In Desperado, when the Mariachi and Bucho finally face off, it turns out that they are both brothers. The Mariachi is Cesar's Manito (little brother in Spanish), while his brother is Cesar.
- In fact, Desperado has a story very similar to Il Trouvatore, where the same thing happens.
- Adam (Cain) and Fenton (Abel) Meiks in Frailty. Adam dutifully followed their deranged father's religious beliefs that he and his sons were hunting down demons on God's orders while they were actually murdering innocent people; Fenton always feared him and knew what they were doing was wrong. After they both left the home, Fenton has been hunting down his brother, who continued to be a serial killer. And then the twist comes...
- In Gattaca, the main character Vincent was conceived without any of the advanced genetic screening that his younger brother Anton receives, and is thus subject to nearsightedness and a high likelihood of developing a heart condition. Their father clearly favors Anton throughout childhood (deciding at the last minute to not name the first-born son after himself when the potential heart condition is discovered at birth, saving that for his perfectly engineered second son). This favoritism coupled with the societal discrimination against naturally conceived "faithbirths" causes Vincent to hide his identity in order to pursue his dream of becoming an astronaut. Later, the police detective who discovers Vincent's deception is revealed to be Anton, who feels insecure about how successful Vincent is despite his "inferior" genetics (due to his determination).
- In The Godfather Part II, Michael Corleone has his brother Fredo assassinated. Granted, Fredo betrayed him first.
- See Michael Myers and his sister from the Halloween movies for the slasher flick take on this.
- Judge Dredd. Rico Dredd, cloned from the same source as Joe, but who became corrupt, forcing Joe to sentence him to the Aspen Penal Colony. Rico returned with murderous intent.
- Marvel Cinematic Universe:
- The main antagonist of both Thor and The Avengers is Loki, Thor's adopted brother. And then in Ragnarok, it's revealed that Thor has an even more murderous and vindictive older sister, Hela, who is more than willing to kill either of her younger brothers.
- In Guardians of the Galaxy, Gamora and Nebula have a relationship very similar to Thor and Loki's. Including being adopted siblings, the Cain having resentment issues because the Abel is the favorite of a father figure and of course Cain and Abel having very tangled love/hate relation.
- In Mortal Kombat: Annihilation, Raiden admits Shao Khan is his brother. (This is a non-canon event created specifically for the film.) This is also mentioned in Mortal Kombat vs. DC Universe, but again, that game is non-cannon.
- The two pharaohs in Night at the Museum: Battle of the Smithsonian: The elder, Kahmunrah, was utterly ruthless while the younger, Ahkmenrah, was kind and intelligent. Their parents gave the throne to Ahkmenrah, and it's implied that Kahmunrah murdered him out of jealousy.
- Perfect Creature has the two vampire brother Silus and Edgar in more than just the literal sense, since they also belong to a vampire organization known as the Brotherhood.
- Prince of Persia: The Sands of Time: Nizam kills his brother because he wants to be king. Then he tries to go back in time to kill him sooner, so he'll be king longer.
- With the release of Prometheus, the relationship between the Humans and the Xenomorphs became something of this trope, as it was revealed that both species were created by ancient, humanoid creatures nicknamed Engineers, or Space Jockeys, in their bioengineering experiments. However, this trope is reinforced as the Engineers created the Xenomorphs in order to wipe out their former creation, the Humans, for reason unknown, and even when it looks like the last Engineer died by the end of Prometheus, the deadly hatred the Humans and the Xenomorphs have to each other still remain active even centuries afterward.
- In The Proposition, Charlie Burns is blackmailed into killing his evil older brother Arthur, using Mikey, the younger, "simple" brother, as leverage. Ironically, their names starts with the initial, C and A. Though Charlie is the Abel and Arthur is the Cain.

Myths & Religion
- The Trope Namer is in The Bible (Genesis, chapter 4). Cain was a farmer, Abel was a shepherd. God wants a sacrifice, so Cain brings the produce of his farm and Abel brings some sheep. God preferred Abel's offering and rebuked Cain for being mad about it whereupon Cain lured Abel into a field and killed him.
- Rudyard Kipling wrote a poem which claims that Abel provoked Cain by wrecking Cain's irrigation project to give the water to his cattle. (He also let them eat Cain's vegetables.) The last two lines of the poem explicitly state that the narrator thinks God's judgment on Cain was unfair.
- The Bible also gives us Esau and Jacob, although they don't end up killing each other. And later, Jacob's son Joseph and his ten older brothers (mixing it with The Unfavorite).
- Another Biblical example, Joseph's 10 older brothers sell him into slavery. In an odd twist, this later saves their lives when he (as second-in-command in Egypt) saves them all from a famine.
- Genesis can be called Cain And Abel The Book with Sibling Rivalry being a major recurring theme. Joseph's story is so heartwarming because this trope is finally subverted and the book ends with a family forgiving each other and coming together.
- Abimelech in the book of Judges murdered all of his brothers, but he missed his youngest brother Jotham. Likewise, Jotham put a curse on him.
- When Israel split in 2, Northern Israel is definitely Cain while Southern Judah is the Abel. Israel was wealthier and more influential but had the political stability of a game of Jenga while Judah was more spiritual and moderate. When these fight, Israel is usually the aggressor.
- The Swedish Jonas Gardell made a point about this in his book About God, where he commented upon the fact that God showed a weird favoritism for younger sons, for no particular reason. It may have tied into favoring the humble, though, as the youngest son would inherit the least.
- The four sons of king David: Absolom, Amon, Solomon and Adonijah. Absolom killed Amon to avenge the rape of their sister Tamar and Solomon sentenced Adonijah to death because the latter had the audacity to ask the hand of their father's widow.
- The Cain and Abel story also appears in Jewish traditions, although there are a few different versions. One of the more common ones explains how mankind learned to murder and why women are more prone to crying when sad. In it, when Cain confronts Abel in the field, Abel warns him that what he's about to do will get him sent to hell, and refuses to defend himself, as he doesn't wish to sin himself by injuring or killing Cain. Cain doesn't know how to kill a person, so the Devil appeared and showed him how by crushing the head of a bird with a rock. Cain mimics it and kills his brother. Afterwards, seeking to cause more mischief, the Devil appears to Eve and tells her that Cain killed Abel. Because no human deaths had occurred yet, Eve was confused and asked what killed meant, to which the Devil told her that it meant that he wouldn't talk, eat, sleep, move,or breath ever again. Eve was immediately sadden and burst into tears. Adam came and asked her what was wrong, but she couldn't speak and kept crying up until the point were the family discovered what had happened. Afterward, Adam declared that from that point on, Eve and her daughters would always cry loudly when someone died, but that he and his sons would not.
- Cain and Abel also appear in The Qur'an, but the story is even shorter than in the bible and doesn't actually give the two brothers names. In this story, The Prophet was told to tell the early Muslims about 'the two sons of Adam'. After his sacrifice was not accepted, the Cain figure told his brother that he would kill him. The Abel figure replied that God would only accept the offerings of people that listened to him and that a murderer would go to Hell burdened by his own sins and those of their victim (the victim would be forgiven as a result of his unjust death). This version of Abel also refused to "stretch out my hands to kill you, even if you stretch out yours to kill me", and said that he feared god and would rather his brother burn in the fire for murdering him than sin himself. Cain was prompted by his 'wicked soul' to kill his brother, and instantly became a lost person for that act. Since he had no clue what to do with the body, God sent a raven to dig up the ground and show Cain how to bury his brother. Cain was mortified and guilty because of the fact that the raven (who had buried another raven) knew what to do, but that he couldn't even give his brother a proper burial. Cain lived out the rest of his life tormented by regret and guilt. This story was meant to explain why Muslims shouldn't murder anyone.
- Like the Christian and Jewish versions, the Muslim version of Cain and Abel has many different versions. In many of them, their names are different. They are also unnamed in some versions, have the same names as their Christian and Jewish counterparts in others, and in yet other versions they are given a variety of different names, with the most common ones being Habil and Qabil (or some other close variants). In the most commonly told rendering of the story, the brother's offered sacrifices to god; Abel was righteous and firmly believed in god,so his was accepted, but Cain was arrogant and prideful, so his was rejected. Cain was the wickeder of the two siblings and he subsequently cornered his brother and taunted him over how he would surely slay him. Like the Qur'an version, Abel told his brother that he was the cause of his own rejection, and that a god fearing person would never harm another, much less murder out of envy. Like in the original, Abel refuses to fight back and preaches to his brother about what the reward for murder will be. His brother's innocent pleading had not effect on Cain's evil heart, and he killed him anyway. After the murder, Cain felt guilt and remorse after a crow had to show him how to bury the body. He realized how horrible the murder of a human being really was and also acknowledged that his murder of his brother was even worse because his brother was innocent and righteous.Cain was condemned for his actions, and lived out the rest of his life in deep regret for his crime.
- Another one of the main variants is that Cain murdered Abel over a woman. When the brother's were born, they were each part of a set of twins and had a twin sister. Since intermarriage was unavoidable, but direct relations marrying seemed inappropriate, Adam decided that the brother's would each marry the other's twin. Cain was unhappy because his own twin was prettier and refused to allow Abel to marry her. Adam proposed that they offer a sacrifice to god and let him settle the matter. Abel had a better and more righteous nature than Cain, so his sacrifice was accepted. From there, the story pretty much follows the two above. In yet another version of the one involving their twin sisters, Cain blamed Adam for praying to god on Abel's behalf for his success and confronted his brother in the field with the intent to murder him. Abel rebuked him and told his brother that he should be more concerned about making his heart right and renewing his relationship with god than marriage. God had blessed Abel with a pure and compassionate heart, so he told Cain that he would let him kill him if it would make Cain feel better, but also begged his brother to not do it, as Abel feared for Cain's soul should he become a murderer. Cain attempted to kill his brother, but found himself unable to do it. At a later time, Adam got worried when Abel was late coming home from his work, so he sent Cain to find him. Cain's anger was rekindled and he proceeded to confront Abel again. Abel repeated his initial warnings but, this time, Cain was intent upon killing his brother and attacked him. In one version of that version, Cain clubs his brother to death with an iron rod. In another version, Abel lays down on the ground and offers his neck to his brother and tells him "Do with me what you will." Cain proceeds to attempt to strangle his brother to death, but fails. The Devil appears to Cain and asks him if he really wants to kill his brother. When Cain answers yes, the Devil instructs him to crush his brother's skull with a rock
- There are literally dozens of Muslim and Arabic variations and explanations of the Cain and Abel story. Sometimes, they even overlap with Jewish traditions and legends;some renderings and retelling's offered by religious scholars are nearly identical. In both religions, many of the more popular renderings state that Cain's motive was marrying his twin. The two religions also overlap on the idea that Cain was taught to murder by the Devil and that Eve is the reason that women are more likely to cry when they are sad then men. Usually in both, Cain is taught to bury the body by a raven or crow sent by god, but Other times Cain runs away and the first funeral and burial is carried out by their parents and sisters when they find the body.There is also a version where Cain runs away with the sister who was the cause of the murder after he kills their brother. In another, Cain states his famous line "Am I my brother's keeper?" when their father can't find Abel and asks him if he has seen him; unfortunately, his remorseless response causes Adam to realize what happened. One Jewish retelling of the idea where the conflict is caused over marriage further explains why the men were matched up with each other's sister's and why God wanted Abel to be the one to marry the more desired sister. Beyond the twincest thing, Cain and and Abel's twin sister were paired together because they were both more bitter and mean; Abel and his intended bride were both more physically attractive and good-natured than their twin's, so god basically paired each brother with the sister who was like him. The reason that Cain was not chosen had nothing to do with his sacrifice itself; he was wicked, unfaithful and ungrateful toward's God, and full of lust for his sister because she was beautiful. Abel was picked because of his righteousness and good heart, like always, only, in this version, it's more logical and practical; he would make a very faithful and loving husband and, seeing that the woman assigned to him was pretty much the female version of him, was the one who would be the better and more happy match for the contested sister. It is also brought up that, after their father told them how God intended for the siblings to be paired off for marriage, Abel was accepting and grateful, not because he got the more beautiful sister, but because he was willing to accept whatever God said. Abel and his future wife are implied to have grown to have genuine faithfulness and love between them after finding out they were meant to be married because they were both totally content with the arrangement; therefor, so it's also possible, according to this version, that Abel was picked due to having a proper and grateful reaction to God's decision. Some scholars believe that Cain was conceived when the either Devil or a fallen angel seduced (or raped) Eve, and that he was therefor destined to be evil. Another idea among scholars is that, after being kicked out of the garden of Eden, Adam unintentionally and unknowingly raped Eve during a fight; They were still naked at this point and had yet to discover what sex was; Adam "grabbed her and held her body to his so that every part of them was touching", not knowing how babies were made; resulting in her becoming pregnant with Cain. The couple was unaware of the fact that their fight resulted in the creation of their son, however, because they learned about what sex was shortly thereafter when god explained it to them. The implication in this interpretation is that Cain was evil because he was created out anger and violence, but that Abel was the better-natured of the two as a result of being created out of love. Another short legend tells Cain repeatedly attempts to wash his brother's blood off his hands while on the run, but the blood refuses to come off. Eventually, Cain comes to a mountain spring and sits with his hands in the water until he dies, his hands still stained with the blood of his innocent brother and as red as the day of the murder. This one is more or less a moral fable/tale, though; the moral of the story is that you can't hide your sins.
- In Mormonism, The Book of Moses clarifies more of the story: Cain loved Satan more than he did God, and Satan told him to make an offering to God, as he does so, only to be rejected because he had no respect for Him. The Lord warns him to be a good person. But Cain ignored this and calls himself Mahan, and made an oath to Satan. He also married one of his nieces and had children with her (we're not kidding), and then you know the rest. Cain then gains a Mark of Shame, given the name Perdition and is told whoever finds him and kills him, vengeance will be brought to him seven-fold.
- Romulus and Remus, the two founders of Rome in Roman mythology. Romulus was Cain to Remus's Abel.
- Brother and sister war gods Ares and Athena would wrap entire nations up in their sibling rivalry.
- Older Than Dirt: Set and Osiris from Egyptian Mythology. Set murdered his brother Osiris and took over Egypt, and later when Osiris' wife Isis tried to resurrect him, Set tore Osiris' body apart. This later caused Osiris' son to seek vengeance against Set after he grew up.

- Norse Mythology:
- Loki betrayed Odin, who was his sworn brother, even if they had different parents.
- Hödr and Baldr, the level depends on the writer. The Prose Edda has Loki tricking Hödr, Saxo says it was because of a love triangle and the Poetic Edda does not state any reason.
- In The Saga of Hervor and Heidrek, Heidrek kills his brother Angantyr (though whether it was accidentally or intentionally varies between the manuscripts)
- The Shahnameh: The person who is finally able to bring down Rostam is none other than his younger half-brother Shoqad.
- Kalervo and Untamo in The Kalevala. The story is laid out in cantos 31 through 36 of the Kalevala. Untamo is jealous of his brother Kalervo, and the strife between the brothers is fed by numerous petty disputes. Eventually Untamo's resentment turns into open warfare, and he kills all of Kalervo's tribe save for one pregnant girl called Untamala, whom Untamo enslaves as his maid. Shortly afterwards, Untamala gives birth to a baby boy she names Kullervo...
- The "Thor vs. Loki" mission from The Avengers (Zen Studios).
- The feud between Bret and Owen Hart. An exception to the "older sibling is always the evil one" rule — younger brother Owen was the heel here. Several years later, Owen and his brother-in-law Davey Boy Smith almost had a similar feud — until Bret stepped in, kicking off the New Hart Foundation angle and stable.
- Edge and Christian during late 2001 to early 2002. At first they were brothers but they were announced as former partners after the feud was over.

Jeff was indirectly involved in angle to cut Matt's legs off though when they both wanted a shot at Rob Van Dam.
- The Undertaker and Kane, who alternate between hating each other and teaming up as the "Brothers of Destruction". Again, Kane is the younger brother (despite being bigger than the Undertaker), and usually the heel when they feud. In fact, Undertaker's original name was Cain the Undertaker. Taker's more identified with death and lightning, Kane is identified with fire and which one set the house fire that killed their parent varies on which one is face and heel. Fridge Logic logic suggests Kane would be the more likely, given he is associated with fire and all.
- When Eddie and Carlito Colón feuded, Eddie was the Abel, despite being the aggressor. This is because after Carly, as he was previously known, came to the United States and started wrestling in Kentucky, he disowned his family, insisting he had no brother when Eddie made a visit to see him.
- When the two oldest Apache sisters feud, it's usually because the second oldest, Mari, has gone bad.

- Dungeons & Dragons:
- Heironeous and Hextor, the gods of Lawful Good and Lawful Evil respectively, are brothers, and sworn enemies. Their appearances are radically different: Heironeous appears as a tall blonde human and Hextor, by contrast, is a six armed ogreish monstrosity. Myths suggest that Hextor may have once been as handsome as his brother, and possibly even a force of Good, but was corrupted and degenerated into his current, ugly form.
- Bahamut, the Lawful Good god of noble dragons, is bitter enemies with his sister Tiamat, the Lawful Evil goddess of evil dragons. They were both created by Io, True Neutral god of all dragonkind, but were not his first creations - his first child was named Vorel, a physically-perfect being with the friendly demeanor, and overall intelligence, of a puppy. Bahamut and Tiamat were closer to what Io was going for, but the two were instant rivals for Io's favor. Tiamat tried to get Bahamut banished by tricking Vorel into destroying some of Bahamut's treasures, claiming her brother flew into a rage, and then murdering Vorel and framing Bahamut for the deed. But Io was patient enough to investigate the matter fully, so it was Tiamat who got banished. Tiamat became the creator of all matter of evil draconic creatures, while Bahamut dedicated this existence to opposing his sibling. Despite this, Io still holds out hope that someday Bahamut and Tiamat will mate and produce the true breed of dragons he envisioned.
- In the Forgotten Realms setting you have the twin goddesses Selûne and Shar. Having supposedly existed since the dawn of the universe and having been so close as to think of themselves as one being, they split apart on the issue of whether giving life to the barren universe would be a good idea. Selûne expresses her views on this matter by creating the Sun, which causes Shar to go Ax-Crazy on her and the entire universe, forcing Selûne to smack her with a Heroic Sacrifice bomb. Millenia later, Selûne's dogma urges you to trust in her radiance and know that all love alive under her light shall know her blessing, while the dogma of Shar features the promotion of misery for its own sake and the direct order to destroy anything Selûne might possibly be related to, in hopes of one day tearing apart the entire universe back into the sweet nothingness it was before this whole pesky 'life' thing. Evidently, they are now not so close as to think of themselves as one being, and the family reunions must be very awkward.
- In the Ravenloft setting, this situation is what doomed Strahd von Zarovich, making him a vampire and the darklord of Barovia. When the beautiful maiden Tatyana rejected him in favor of his younger brother Sergei, Strahd developed jealousy of Sergei that eventually blossomed into hatred. He eventually made a pact with some dark entity (Strahd claims with death itself) and on the day of Sergei and Tatyana's wedding, he murdered his brother, and then tried to pursue Tatyana, only for her to flee from him and throw herself from the walls of Castle Ravenloft. This horrid act cursed Strahd forever, transforming him into a vampire, making Barovia the first recorded domain of Ravenloft with him as its lord, and tormented by images of Tatyana (or women who look just like her) ever since.

- Warhammer 40,000 has the rivalries between the Primarchs, the Emperor's clone-sons and the leaders of his armies, which escalated into the galaxy-shaking bloodshed of the Horus Heresy. These struggles are continued by the Space Marines and Chaos Space Marines, entire armies of superhuman, genetically-engineered brothers trying to murder each other.
- Fulgrim and Ferrus Manus had a shared obsession with perfection that forged them into good friends, which was why Fulgrim tried to talk Ferrus into going traitor along with him. When Ferrus refused and challenged his brother to battle, he became the first Primarch to die during the Horus Heresy.
- Konrad Kurze ended up capturing and killing Vulkan, several times, as part of an attempt to break the loyalist Primarch.
- Leman Russ of the Space Wolves and Magnus the Red of the Thousand Sons were natural rivals, since Russ was a barbarian warlord with a superstitious hatred of sorcery and Magnus was the most powerful psyker among the Primarchs, and the most clearly inhuman. So when Magnus broke the Emperor's ban on sorcery, it was all too easy for Horus to trick Russ into trying to kill Magnus, rather than apprehend him like the Emperor had actually ordered. The tragedy is that Magnus had used his powers to try to warn his father about Horus' betrayal, but being attacked by the Wolves drove the Thousand Sons into the traitors' camp.
- Sanguinius and Horus were once close enough to confide their deepest fears to each other, and each assumed the other was the best choice for Warmaster. During the final battle of the Horus Heresy, Sanguinius still tried to talk his fallen brother down, but was forced into battle and slain by Horus.
- Perturabo of the Iron Warriors and Rogal Dorn of the Imperial Fists were rivals for a long time before the Heresy. Both Primarchs were siege experts and had incredible engineering skills, but Dorn received the privilege of building some of the greatest works of the Imperium, including the Imperial Palace on Terra, while Perturabo and his legion were pigeon-holed into digging trenches and garrisoning planets, with no glory and no thanks. Perturabo wasn't happy about this, especially when Dorn told their brothers that he could tear down any fortification with the proper resources, including anything Perturabo built. This lack of respect, especially from Dorn, was what helped pushed Perturabo into the traitor's camp and made him take great pleasure in destroying the Imperium's works. And during the "Iron Cage" incident, Perturabo did in fact build a massive fortress and dared Dorn to try and break it down. Dorn did...and nearly got himself and all his sons killed in the long siege and traps Perturabo set.
- After the Heresy, Roboute Guilliman was mortally wounded by the now-daemon prince Fulgrim, but was placed in stasis for nine thousand years before being healed and returning to battle. Then when he headed for Terra, Magnus the Red nearly killed Guilliman on Luna.

- Also in As You Like It, Duke Frederick has deposed his older brother, Duke Senior—who embraces his exile, choosing to live with his entourage like merry men in the forest—but in the meantime the rivalry drives Duke Fredrick to banish Senior's daughter, Rosalind, for fear that her presence at court will stir up sympathy for the old duke. Eventually, Duke Fredrick finds religion and returns his brother's dukedom.
- In King Lear, Edmund the bastard manipulates his father into believing his half-brother, Edgar, is conspiring against them and gets Edgar banished so that he can inherit his lands instead. The plan ends up snowballing into a bid for the English throne, but in the final act Edgar returns from exile and anonymously defeats Edmund in a duel, only revealing his true identity when his brother lies dying.
- Also in King Lear, the rivalry between Lear's older daughters, Goneril and Regan, who are lying, manipulative bastards, and his youngest daughter, Cordelia, who is honest and virtuous. It doesn't end well for any of them.
- Don Pedro and Don John in Much Ado About Nothing. Don Pedro is the prince of Aragon, and Don John is his younger, illegitimate brother. When the play opens, Pedro has just defeated an uprising led by John, so John takes it upon himself to be the villain of the piece and interfere with his brother's romantic machinations however he can—though he ends up just angsting for five acts while his minions do the evil stuff for him.
- Richard, Edward, and George in Richard III. They stuck together during the revolution of the previous play, which saw Edward ascend the throne, but Richard has his heart set on the crown and won't let his older brothers stand in the way.
- Since pretty much all the English kings have been part of one Big, Screwed-Up Family, most of the histories see some permutation of second cousins twice-removed competing for the throne or other.
- Prospero of The Tempest is "the wronged duke of Milan," deposed by his evil brother Antonio. When Antonio's ship passes by the island Prospero has made his home, the magician sees an opportunity to right an old wrong . . .
- Action figure super-hero Stretch Armstrong has a villainous brother named Retch Armstrong.
- From BIONICLE, Mata Nui and evil Makuta Teridax, who put Mata Nui to sleep, were presented as this in legends. Subversion: Turns out the legends were lies, and while Mata Nui's really a Physical God Big Good, Makuta was only one the beings living inside him. Double Subversion: Makuta always called him "brother" (partly because he originally served on his side, partly because he saw himself as equal), and eventually usurps him, taking over his body and forcing Mata Nui to fight him using his prototype body.
- Age of Wonders has Meandor and his half-sister Julia. They got better, even becoming allies in Shadow Magic.
- Assassin's Creed IV: Black Flag strongly suggests that the Assassin Opía Apito and the Templar Lucia Márquez were actually half-sisters with the same father, though neither woman seemed aware of this. The former is obviously Abel in that she was trying to protect her tribe from the Cain Lucia's attempted genocide of them for the (likely justified) death of her father at the tribe's hands.
- In Backyard Sports, Angela and Tony Delvecchio, siblings, play better on opposite teams in many games. This makes it tough to defeat one sibling using the other on a team.
- Baldur's Gate plays this trope straight in the first game, then takes it to its logical extreme in Baldur's Gate II: Throne of Bhaal, wherein five of the six required bosses are siblings of the player and of Imoen, who may or may not be in the party.
- Hinted at in The Binding of Isaac. One of Isaac's playable "siblings" is the literal Cain, and a power-up is a ghost baby named Abel. Whatever Isaac/Cain does, Abel does the opposite. If fan theory is to be believed, Cain and Abel represent Isaac and Maggy, as he feels guilty for hating her while she was alive, and blames himself for her death.
- A lot of drama in BlazBlue is centered on protagonists, Ragna the Bloodedge and Jin Kisaragi. Their bad blood comes mainly from Jin abandoning Ragna to die in their burned down Church home and letting their sister Saya be kidnapped when they were children. Jin's motives are mainly: 1) Since Ragna would eventually become a harbinger of destruction due to gaining an Artifact of Doom after said Church incident, Jin was chosen by the powers that be to be an "Antibody" to stop him. 2) His sword is an Evil Weapon and drives him to homicidal psychosis whenever he's around Ragna. Naturally, they can't stand each other, even when they're on the same side eventually.
- In Boktai, Django later finds out Sabata is his (initially) evil, half-brother.
- Borderlands gives us Jaynis and Taylor Kobb. Taylor hires you to kill his brother so he can take over Jaynistown… and then turns out to be even worse so you have to kill him too.
- The ending of Breath of Fire III reveals that Bleu/Deis, protector of the Dragons, is actually the Goddess Myria's sister.
- Capella's Promise has the princes, Zanara and Wolt, who go to war with each other because the former (the Cain of this relationship) is using an ancient weapon to turn their citizens into a monster army. The main character Velk turns out to be their half-brother and sides with Wolt, but he doesn't exactly fit into this dynamic because he doesn't personally know Zanara.
- In Clive Barker's Undying, all the Covenant children fell to the curse of the Undying King, only to be resurrected as monstrous forms of their previous selves. They're out to kill Jeremiah, the last surviving son, to complete the curse.
- There are also Bethany and Aaron, twins who utterly despised one another and were in constant rivalry. Bethany won, by chaining up her brother in a dungeon accessed through her room to be eaten by rats, and removing his jaw so he couldn't scream.
- In Command & Conquer: Renegade, the series-wide Big Bad Kane is hinted to be the biblical Cain, as the Temple of Nod in Cairo has Abel's tomb in its catacombs.
- Aku Aku and Uka Uka in the Crash Bandicoot series.
- Kasumi and Ayane of Dead or Alive. They were best friends as children, especially given Ayane's status as a village pariah. When they discover that they are half-sisters and Ayane is the product of rape, Ayane turned on Kasumi out of jealousy that the former was raised in luxury and beloved by everyone while she was scorned and hated by the same people, and is currently the one tasked with assassinating Kasumi after she left the village to pursue Raidou. Unlike most examples, however, Ayane isn't evil, just Anti-Heroic, and as of the ending of Dead or Alive 5, they seem to have reconciled.
- Dante and Vergil of Devil May Cry. In the original series, it was primarily Dante and Vergil's differences in regards to which side of their nature they embraced, while in the new game, it is more a question on whether the Nephilim should let humans decide their own fates (Dante) or rule over them (Vergil).
- It's quite literal in Devil Survivor, where Naoya, the protagonist's older cousin, is revealed to be the original Cain, while the protagonist possesses Abel's essence (along with a bunch of other people, apparently). The dynamic's a little different though, as Naoya does not want to hurt the protagonist: He wants to make Abel reject God and become the king of Bel, and serves as a Stealth Mentor for most of the game to nudge you in that direction. He will only fight the protagonist's group in the Law and Atsuro endings, and in the latter case it's more a Secret Test of Character to see if the protagonist has the will to enslave the demons.
- This trope is what led to Fuuka's murder in Disgaea 4.
- This comes up several times in Dragon Age II. Near the end of Act I, Bartrand succumbs to greed and the lyrium idol's curse and tries to kill Varric to avoid sharing the wealth. Varric can either kill Bartrand as payback, kill him to save him from the lyrium idol's corruption, or put him in an asylum to care for him. In the "Fool's Gold" sidequest the middle brother Iwan leaves his older brother Emerys and his younger brother Merin to the darkspawn so he can claim a valuable magical sword for himself. Varric will even mention that this story is awfully similar to what happened to him. In the endgame, if Hawke supports the Templars, he/she may end up fighting and executing Bethany if she joined the Circle. Oddly enough, Hawke's more antagonistic sibling Carver will never fight Hawke and even defends him/her as a Templar when Meredith orders him to kill Hawke. This can also occur with Fenris and his sister Varania after she sells him out to his former master so that she can become a mage apprentice. If the player does not interfere, Fenris will kill her.
- The Elder Scrolls
- In the series' lore, Anu and Padomay are the anthropomorphized primordial forces of "stasis/order/light" and "change/chaos/darkness", respectively. They are usually referred to as brothers, twins to be specific. Their interplay in the great "Void" led to Nir, "creation". Nir loved Anu, which Padomay hated. Padomay wounded Nir, but before dying, she gave birth to twelve worlds. Padomay shattered these worlds but was stopped by Anu, who wounded Padomay and presumed him dead. Anu then salvaged the pieces of these worlds to create one world, Nirn. However, Padomay returned and wounded Anu, spilling both of their blood. Anu pulled Padomay outside of time itself, ending his threat to creation. From the blood of Anu and Padomay came the et'Ada, or "original spirits", who would go on to become either the Aedra or the Daedra depending on their actions during the creation of Mundus, the mortal plane. (Some myths alternatively state that the Aedra came from the intermingled blood of Anu and Padomay, while the Daedra came only from the blood of Padomay.)
- The Dren brothers - Vedam Dren, the noble duke of Vvardenfell, and Orvas Dren, the leader of the xenophobic criminal organization, the Camonna Tong. Vedam doesn't want his brother killed, but isn't overly angry if it comes to that, while Orvas… is planning to murder his brother, which you can use to blackmail him if you find the implicating letter.
- Sjoring Hard-Heart and Radd Hard-Heart. Sjoring is the leader of the Fighter's Guild and very much in the pocket of the aforementioned Camonna Tong while the other is an honorable officer of the Imperial Legion.
- Mickey Mouse and his older half-brother Oswald the Lucky Rabbit are this in Epic Mickey.
- Exit Fate also contains two such siblings (in this case, twins of opposite genders): Brunhild and Daniel. Clearly, SCF likes putting siblings at odds with each other…
- The premise of Fable III. Big Bad Logan is the tyrannical ruler of Albion you must overthrow and the son of the previous game's player character. He also happens to be your older brother. Depending on your own approach, you can potentially be better or worse than him.
- In FEAR, it's explicitly canon that Alma (the homicidal female ghost) is the Point Man's mother, Paxton Fettel (The Dragon) is the Point Man's brother, and the Mad Scientist responsible for the creation and birth of both the Point Man and Fettel was Alma's father Harlan Wade, who ruthlessly exploited his naturally born daughter's psychic abilities in an attempt to create Super Soldiers. All in all they're a Big, Screwed-Up Family.
- Fear Effect: Retro Helix. Glas and Drew, with Glas being Abel and Drew being Cain. Rain and Mist, with Rain being Abel and Mist being Cain. Subverted in both cases, with Glas and Rain not only surviving the attempts on their lives, but end up killing off Drew and Mist.
- This happened to no end to Cecil in Final Fantasy IV. His best friend and comrade in arms who betrays him is actually 'named" Cain. (Kain in the original North American release, because I guess it was too obvious otherwise?). The second time it was revealed that Big Bad Golbez was his actual brother. Of course, it was revealed in the end that both were actually just being mind-controlled by the Man Behind the Man.
- In the DS version, it is revealed that Golbez, known way back as Theodor, was compelled by Zemus to abandon his baby brother in the woods outside Baron. If you're wondering why Cecil thinks the king as his own father up until The Reveal, now you know.
- To be fair to Golbez, he pretty much makes up for being the Cain in the Sequel when he performs a Heroic Sacrifice. Even in the Crisis Cross Over Dissidia: Final Fantasy he ends up being the game's Stealth Mentor.
- And to drive the point home, you can not only get Kain's Lance, but Abel's Lance in a bonus dungeon of the GBA version.
- Interestingly, Dissidia: Final Fantasy reveals a similar relationship between Chaos and Final Fantasy I's Warrior of Light. The twist being that neither knows of the connection.
- Kuja and Zidane of Final Fantasy IX.
- Tons of examples in the Fire Emblem franchise.
- In Fire Emblem: Shadow Dragon and the Blade of Light, Minerva and Michalis come to blows over the direction Macedon should go; Michalis wants a strong nation allied with Dolhr, while Minerva wants a compassionate nation allied with Altea. Amusingly averted with the two guys actually named Cain and Abel, who are both Marth's loyal grunts throughout the first game. It's actually Abel who turns on you in Fire Emblem: Mystery of the Emblem and Tokyo Mirage Sessions #FE, and then only because I Have Your Wife and Brainwashed and Crazy are respectively in play.
- Fire Emblem: Genealogy of the Holy War: First the brothers of Rebel Prince Jamke are brutish pawns of a cult. Afterwards comes Andorey, the younger brother of Briggid, who killed his own father to get the title of Duke. There's also Danan, the evil brother of Mad Dictator's Handsome Son Lex. Similarly, Mad Scientist's Beautiful Daughter Tiltyu's brother Bloom took after their father. At the end of the Wham Episode, Arvis betrays and murders his own half-brother Azel (and all of your other guys for good measure). Near the end Burian, the emancipated but super strong brother of Johan/Johalva shows up for revenge. Finally there's Princess Julia who is good when she is not brainwashed and has the gamebreaking Naga light magic, while her twin brother Prince Julius is the inbred vassal of Loptyr who (barring Cherry Tapping) needs to be killed with Naga and wields dark magic. Yes, Genealogy of the Holy War IS creepy.
- Furthermore, only one of the pair of Johan and Johalva can be recruited, making the non-recruited one turn against his brother. And most significantly Prince Seliph is also Julius's half brother.
- In Fire Emblem: The Binding Blade there's Nietzsche Wannabe King Zephiel and his much gentler half-sister, Princess Guinevere. They did not start out that way, being very close in their childhood, but after an assassination attempt by his own father, Zephiel became embittered and eventually drove his sister away.
- Fire Emblem: Path of Radiance's Mad King Ashnard fits, what with killing all of his other siblings in order to take the Daein throne and all.
- In Fire Emblem Fates, the Avatar will always be forced to turn against one set of siblings. In Birthright s/he's the Cain to Xander, Camilla, Leo, and Elise's Abels, while in Conquest s/he's the Cain to Ryoma, Hinoka, Takumi, and Sakura's Abels. Conquest also has the ninja Kaze betraying his brother Saizo to join the Avatar; ironic because Kaze is a member of the Abel archetype while Saizo is the game's Cain archetype. Unusually, these Cains are genuinely sympathetic heroes who only betrayed their siblings as part of a Sadistic Choice. There's also a more straightforward example in Birthright, where Flora is forced by Garon to battle the Avatar and comes to blows with her sister Felicia.
- Galerians: Rion and, uh… Cain. The rivalry is entirely one-sided on Cain's part, since Rion has no way of knowing that a backup Rion clone was made specifically to kill him.
- Kratos actually has several of these in God of War Series, being a son of Zeus and all, the foremost being Ares, who tricked him into killing his wife and daughter. In only two cases, however, is the connection actually remarked upon; with Hercules, a "Well Done, Son!" Guy who hopes to surpass Kratos, and Athena, who plays the role of ally, reluctant enemy, ally again, and finally Bitch in Sheep's Clothing.
- In Grandia II the main character must fight his older, more skilled, possessed brother.
- Some examples in the Heroes of Might and Magic series:
- The fathers of Morglin and Ragnar in backstory of the first game: Ragnar's father murdered Morglin's father to seize the throne, and then he left the throne to Ragnar upon his own death. It's easy to infer from Morglin's unreliable narrations that he, Morglin, had attempted to have Ragnar killed too.
- Roland and Archibald Ironfist. Though, ultimately, neither brother is willing to go all the way: in their respective endings in Heroes II, Archibald gets Taken for Granite and Roland is imprisoned in the western tower (canonically, the first is what happened), and when next the two brothers meet, Archibald helps save Roland, taking him to Roland's wife despite knowing full well that she has every intention of executing him should she get the chance — Roland, in turn, intercedes on Archibald's behalf and gets the sentence down to exile.
- Ros and Lazarus in I Miss the Sunrise.
- Jade Empire: Emperor Sun Kai and your mentor Sun Li. Though it turns out they're both evil, Master Li just wanted the throne for himself and trained you as a weapon against him, and he kills you once You Have Outlived Your Usefulness.
- In Kid Icarus, Palutena and Medusa, sister goddesses of light and darkness respectively, have this type of relationship. It's not hard to guess which one is the evil one. It's subverted in that Palutena did not kill her herself, she only turned her into a monster and banished her. The angel Pit finished the job.
- Kingdom Hearts: Birth by Sleep actually turned the relationship between Cinderella and her evil step-sisters into this. While they were very cruel to her in the films, they outright tried to murder her out of hatred with an Unversed in the game, which backfired on them spectacularly.
- Last Scenario has Castor and Ethan, respectively, including the age rule. However, it's pointed out that the younger of the two plays the role of an older sibling in many respects, which may make this a slight variation on the usual set-up.
- League of Legends has several pairs. Kayle and Morgana are ancient angels locked in an Order Versus Chaos war with each trying to gain the power to defeat the other. Nasus and Renekton were heroic brothers until Renekton attempted Sealed Evil in a Duel on a maddened Xerath and emerged centuries later with nothing but an insane hatred for his brother. Yone was Yasuo's only defender until he believed (false) accusations that his brother had murdered someone; he challenged Yasuo to a duel of honor, forcing Yas to cut him down.
- There's a sidequest in the first Mass Effect game in which Nassana Dantius, an asari diplomat on the Citadel, asks you to rescue her sister, Dahlia, from slavers. After you defeat the slavers, you find out that Dahlia was the leader of the slaver group. Who you killed. Nassana wanted Dahlia dead because having a slaver sister would possibly hamper her career. This is actually kind of funny due to the fact that her voice actress voiced Azula.
- The Snake Brothers (okay, "Les Enfants Terribles", strictly) in the Metal Gear series. Liquid seems to enjoy the rivalry immensely. Perhaps a little too much.
- It's no coincidence that their mother's codename is EVA. She's explicitly linked with Eve, and not only by reference to her sons — this is her on the boys' father, who at the time went by the codename Naked Snake: "But… it was I who tempted the Snake, and got away with the forbidden fruit of knowledge."
- The trailers for Modern Warfare 2 explicitly invoke the murder of Abel, with Makarov talking about the blood of those killed by the United States and the UK crying out from the earth, and noting that they cannot hear the cries because they do not come from their own soil… but they will.
- In Mortal Kombat, Bi-Han, the original Sub-Zero, was killed by Scorpion and resurrected as the evil revenant Noob Saibot by Quan Chi, the true author of the events that led to Scorpion's vendetta against Sub-Zero. This puts him up against his younger brother Kuai Liang, the second Sub-Zero, who also opposes Quan Chi.
- Mileena is an Evil Twin knockoff to Kitana and wants to kill her.
- In MOTHER 3, Lucas must fight his brother Claus, who was killed, reanimated, and brainwashed into being the Pig King's loyal minion. When Claus snaps out of it, it's too late.
- The Shimada brothers Hanzo and Genji from Overwatch. Elder brother Hanzo is a dutiful son to his family's crime business, while the younger brother Genji is a pampered boy with no interest in crime. Then Hanzo, on the order of the clan elders after his succession, attempted to put Genji into the fold, he refused, Hanzo ended up killing him, which caused him to leave the clan in shame and attempts to redeem himself through his way. Little does he know that Genji came back as a Cyber Ninja, shut down his family business and shows himself to Hanzo, forgiving him for his actions, but due to complicated reasons, Hanzo wasn't as accepting. Genji is a member of the Overwatch, the good guys, Hanzo right now is a neutral figure, but both still have tension against each other.
- In SaGa Frontier, there are Blue and Rouge, twins who're told to kill the other after mastering as much magic as possible. Who wins is irrelevant, since they turn out to be the same person, Split at Birth.
- The obscure PC game Sanity: Aiken's Artifact feature such a storyline with someone named Cain as the protagonist and the so-called foster brother Abel as the final boss.
- In SoulCalibur V, Sophitia's children Patroclus and Pyrrha are driven to this thanks to being egged on by Soul Calibur and Soul Edge respectively. Fortunately, the siblings are strong enough to eventually overcome the influence of both swords for each others' sake.
- Soulcalibur IV Sophitia becomes the Cain to Cassandra's Abel, but not willing because she has been Forced into Evil.
- In Starsiege, two mech pilot brothers are codenamed… Icehawk (the older, a cold-blooded by-the-book pilot who is loyal to the Emperor) and Phoenix (the younger, a prodigy pilot who has a knack for escaping from impossible situations and joins the Mars Rebellion). They are and are not actually related: Icehawk's real brother was critically injured in an accident and the Emperor secretly had his brain replaced by the organi-mechanical brain of his own son, as a way to continue his son's existence. Indeed, a hidden sect of people in the game world do this with their brains all the time, choosing children with life-threatening injuries and swapping brains with them while they're hospitalized.
- In the Knights of the Fallen Empire expansion of Star Wars: The Old Republic, Arcann killed his twin brother Thexan when he lashed out at his father Emperor Valkorian and Thexan tried to stop him. It was this act however that led to Valkorian acknowledging Arcann has his heir.
- Street Fighter IV. It's a definite shout out to the bible, a hero being named Abel, only the Cain is named Seth. It's made very obvious that Abel is a product of S.I.N. experiments like Seth, in both his Ultra Combo (Where his eyes change color to resemble Seth's), Abel's ending, and both of their win quotes against each other in Arcade Mode. According to Word of God, Seth was indeed originally going to be named Cain, but this was changed due to some other fighting game having a character with a similar name. It also helps that Seth is the name of Capcom's senior manager, Seth Killian, also known as "S-Kill". This also works for Akuma and Gouken.
- Zigzagged in Tales of the Abyss. The game is kicked off by Tear's attempt to kill her brother Van, making it seem like Tear is the Cain to Van's Abel, which is eyebrow-raising due to Tear's status as the Deuteragonist. Then Van is revealed as the Big Bad and that Tear had a very good reason for trying to kill him, making it seem like Tear is the Abel to Van's Cain. As more about Van's goals are revealed, it's discovered that while Van is determined to destroy the world, he is also desperate to keep Tear alive if at all possible, settling the situation on a heroic Cain going up against a villainous Abel. Then, by the end of the game, Tear has experienced Character Development and makes one last attempt to convince Van to settle things peacefully, while Van declares that he will no longer hold back, even against her, reversing the situation one more time into Tear being the Abel to Van's Cain.
- Redmond and Blutarch Mann from Team Fortress 2, to the point that not even death can stop the rivalry between them; when they're both killed by their long-lost brother Gray Mann in the comic prologue to the Mann vs. Machine update, their ghosts later hire the mercs to send the other brother's corpse to Hell so they can legally be the winner of the war between them as part of the 2013 Halloween event.
- In the fashion of the Tekkaman Blade example, Super Robot Wars Compact 3 gives us sworn brothers Folka Albark (the elder, main protagonist) and Fernando Albark (the younger rival). Then there's their older brother Altis Tarl, also in the enemy's side. Subverted because Fernando and Altis are not outright evil, they're just Folka's enemies on circumstances.
- The first Original Generation game has brothers Raideisse and Elzam Branstien fighting for the first half of the story. Mostly because they happen to be on opposite sides of a war, but it also brings out a measure of animosity, mostly on Rai's part, over the death of Elzam's wife (long story), whom it's suggested Rai was in love with.
- In Super Robot Wars NEO, Amane Inaba when possessed by Larva is the Cain and Kakeru Inaba is the Abel.
- Tekken has Nina and Anna Williams.
- Kazuya Mishima and Lee Chaolan fit this trope as well since, technically Lee is Heihachi's son through adoption.
- Likewise with Kazuya and Lars, since Lars is the son of Heihachi and a Swedish mistress.
- Jacky and Sarah Bryant from Virtua Fighter had to go through this. In the first two tournaments, J6 brainwashed her and had her try to kill her brother. After she was freed from their control, her motivation for joining recent tournaments was to fight and defeat her brother, not knowing this is all part of J6's plot.
- In the Warcraft universe, night elf twin brothers Illidan and Malfurion Stormrage are Cain & Abel respectively. Illidan became a demon literally due to his consuming the power of the Skull of Gul'Dan and figuratively due to his addiction to magic. That said, Illidan never attempted (at least intentionally) to kill his brother.
- His jealousy over priestess Tyrande Whisperwind choosing his brother over him was actually the plot point that fixed their 10,000-year-old-feud. Events spanning throughout the third game and its expansion culminate in the brothers teaming up to save Tyrande and making up before Illidan leaves Ashenvale (for reasons not revolving around the Night Elves).
- In the backstory, Darion (Abel) and Renault (Cain) Mograine become this, fueled by their father's perceived Parental Favoritism toward Darion. Though Renault turned his ire on Dad first.
- In World of Warcraft, this happens with Krenna and Gorgonna in Conquest Hold. Krenna, the commander, wants to wage war on the alliance, and the more reasonable Gorgonna doesn't want it to happen. In the last quest in the chain, you fight alongside Gorgonna against Krenna and her bodyguards, killing Krenna and allowing her to take command. Despite the fact that she knew killing her was necessary, Gorgonna mourns the loss of her sister.
- During the events of Wolfheart, Jarod Shadowsong (Abel) and his sister Maiev (Cain). Near the end of the novel, they had a bloody confrontation when he had discovered she had captured and planned to kill Malfurion Stormrage; he couldn't bring himself to kill her and she fled.
- Based on a line of dialogue from the finale of the Sunwell Plateau raid, possibly Velen (Abel) and Kil'jaeden (Cain). Noteworthy in that this particular rivalry has had repercussions affecting the inhabitants of many planets.
- The ridiculously gory and difficult adventure game Wax Works was built around this concept. Your family was cursed so that one of every set of twins becomes evil, and you have to go back in time using the titular waxworks building to kill the worst of them and break the curse. Your own brother is incapacitated before and throughout the game, and part of your goal is to save him, but other than this, the "evil twin" aspect isn't played up much: the evil brothers of the past include Jack the Ripper, a necromancer who looks far older than his good twin, and a human/fungus mutant who doesn't even resemble a human anymore. That is, until The Reveal that you were the evil twin all along.
- Xeno Gears has a character named Abel, and a character named Cain. Cain was (indirectly) the one who killed Abel. That's about where the similarities end.
- In Dragon's Lair II, the Evil Wizard Mordoc's brother is the talking, rhyming, Time Machine who acts as Dirk's advisor and means of chasing Mordoc through time. (And no, it's never revealed how they can be brothers.)
- Ace Attorney:
- An adopted example: Franziska von Karma from Phoenix Wright: Ace Attorney has some severe issues with her adopted "little brother" Miles Edgeworth. She's determined to outdo him in nearly everything, especially prosecuting, and is unhappy that she won't get to prosecute before he does (even though she's seven years younger than he is). Edgeworth doesn't seem to care very much, which only infuriates Franziska more.
- In Apollo Justice: Ace Attorney, Kristoph and Klavier Gavin are respectively Cain and Abel, with Kristoph being an Amoral Attorney who is responsible for Phoenix getting disbarred, and Klavier being a more moral prosecutor.
- In Phoenix Wright: Ace Attorney – Spirit of Justice, Ga'ran is the Cain to Amara's Abel. She framed her brother-in-law for a faked assassination to usurp control of the country from her sister, and outright had her sister shot when she was about to expose her crimes.
- Shiki and SHIKI in Tsukihime. Best friends, adopted siblings. Then SHIKI goes crazy because Roa possessed him plus his inversion went off. Still, turns out if they're able to meet on friendly (Kagetsu Tohya) or semi sane (Kohaku's route) terms they still actually get along quite well, and he's not really that bad a guy.
- Also from the Nasuverse are the Aozaki sisters, Touko and Aoko, although the details aren't clear.
- Umineko: When They Cry has four siblings in one Big, Screwed-Up Family. It also subverts the usual "brothers or sisters" rivalry. Krauss is largely resented by his younger siblings, particularly Eva, who actually takes her resentment out on Krauss's wife, Natsuhi. All four of them are pretty messed up, though, due to being raised by Kinzo, and at certain points, even Krauss and Rudolf admit that they wish they'd been better older brothers to Rosa.
- Twin brothers Leni and Seizh of Under the Moon seem to get along fine at first, but Seizh's simmering inferiority complex regarding his more successful sibling is itching for an outlet.
- In American Barbarian, Rick finds himself fighting his oldest brother. And realizes he was party to the deaths of their other five brothers.
- Bob and George: Bob likes to burn things and George likes ice cream. Plus at the end it is revealed that this was all a plot to ensure that the hero George would kill the villain Bob if he had to.
- Since robots from the same creator are termed siblings, a good number of other fights.
- Ctrl+Alt+Del's Rory and Ethan.
- Isaac Jenner and his brother Gabriel from Demonology 101 respectively, with a slight variation in that Issac is the younger brother whereas in most cases the older brother is portrayed as the villainous one. His hatred stems mainly from his status as the The Unfavorite, both in the eyes of his father and those of The Powers That Be. Isaac mellows out a bit after meeting Madeline, a demon whom he falls in love with, and eventually gives up on trying to kill Gabriel as part of a deal with The Hero to save her life.
- Dominic Deegan: Oracle for Hire sometimes pits Dominic and Gregory against their necromancer brother Jacob. Early on, there was an interesting twist: Dominic hated Jacob, but Gregory still wanted to believe the best of him.
- Luna's relationship with her sisters was also like this for a while, but the three eventually decided to try and at least tolerate each other after the rest of their family got themselves killed with their petty fighting.
- In Drowtales, this tends to happen due to Royally Screwed Up families:
- Vy'chriel and Yaeminira. Yae was an adopted "protector twin", and The Unfavorite. She killed Vy'chriel for the crime of refusing to tow the family line and took her name.
- The fandom now fears for Chrys and her "protector twin", Shinae. Chrys' mother actually warns them against betraying each other with a story about the first "protector twin", and what happened when the true daughter betrayed her.
- To a much lesser extent, Ariel and her older "sister" Syphile. Syphile was forced to become Ariel's Governess, despite having never been trained in childcare. After years with a Babysitter from Hell, when asked what she would most like to do, the ten-year old Ariel unsurprisingly replies "kill Syphile".
- Another example with Ariel is with her half-sister Kalki, who goes so far as to stab Ariel in the hand and then chop off her arm they very first time they meet.
- The Villain Protagonist of His Face All Red kills his older brother out of jealousy. When a week later the brother walks back into town as if nothing had happened, then things get really spooky.
- Haru-Sari: Noel and Leon.
- In Homestuck, the Cherub Caliborn loathes his "sister" and split personality Calliope. He murdered her dreamself before he even started his session of Sburb. As Lord English, he is still hung up on his hatred of his sister. He destroys entire dream bubbles — tearing reality apart in the process — hunting his sister's ghost so he can finally make her Deader Than Dead. Arguably, everything bad in the entire story can be traced back to Caliborn's desire to destroy his sister and everything his sister loved.
- In It's Walky!, Walky and his separated-at-birth sister Sal have fought each other at least twice, and they get pretty rough. Also, Beef, who was believed to be Walky's twin brother, betrays SEMME in part because of being upstaged by his puny airhead adoptive brother.
- Lin T: Fang and Sangwine.
- The Order of the Stick:
- Elan and Nale. Nale is confused when he finds out that Roy and Julia Greenhilt actually get along. He thinks this trope is normal. And so does his girlfriend.
Sabine: Some families are just... different.
- And Redcloak and Right-Eye, in a more heart-rending and sympathetic example. Redcloak didn't kill his brother over rivalry, it was because of his Fatal Flaw.
- Elan created a situation like this between his puppet Banjo the Clown and another puppet Giggles the evil Clown god of slapstick. Since deities are powered by belief, the two of them are actually gods now that an entire orc tribe worships Giggles and Banjo is his equally powerful rival. Elan liked the orc high-priest of Giggles' suggestion that the two were brothers.
- Elan and Nale. Nale is confused when he finds out that Roy and Julia Greenhilt actually get along. He thinks this trope is normal. And so does his girlfriend.
- In Penny Arcade, Tycho once compared his relationship with his brother to this:
Gabe: Is that bad? Aren't you guys brothers or something?
Tycho: You might recall that Cain and Abel were brothers.
- In Plume, the eldest princes of Auru had this dynamic, with the twist on the story being that it was the younger who ended up killing the older.
- In Sandra and Woo, a nature documentary showing this among birds unnerves a little sister.
- Cain and Abel from Serpamia Flare. A bit of a literal demonstration of this trope in the names; Cain has great trouble talking about his brother in Chapter Two and refers to him in past tense, while Abel expresses extreme distaste/anger at the mere suggestion that Cain may be involved with a situation at hand at the end of Chapter Two. They seem to have some past issue, though a hint in Chapter Three suggests the two brothers weren't always on bad terms.
- Slightly Damned has an adoptive variant with Buwaro and Sakido as different kinds of Abel and Iratu as the Cain. Buwaro is kind-hearted and tries to help others, Sakido wants to make-up for scaring and abandoning Buwaro when he was a toddler as well as the things she's done in Hell and ends up dying getting him and his friend Rhea out of Hell. Iratu on the other hand became a General for the army of hell and leads them in an attack to conquer Medius, he still loves Sakido but hates Buwaro and when he learns she died for him he tries to kill Buwaro himself.
- Oasis and Kusari in Sluggy Freelance. Oasis actually killed Kusari once, but she got better. Admittedly, it's unclear if they're siblings in the traditional sense of the word, or if it's some weird clone/other-half-of-a-supernatural-force thing or what-have-you.
- Can we mention everyone's favorite Yaoi webcomic, Starfighter? They're not brothers or even friends, but Cain is the codename of the violent Seme and Abel is the much nicer Uke.
- 8-Bit Theater's Black Mage once watched his own blind brother stumble around an uneven room laced with knives and tiger pits, even going so far as to push him when it seemed said brother would survive the ordeal. Of course, it would have been cruel to let him live after what he did to his eyes…
- In Bad Moon Rising, this is the dynamic between Chloe and most of her siblings, but most especially her brother Derek.
- In The Gamer's Alliance, both Refan and Zarnagon and Leraje and Ronove are this as they work for opposite sides in the war.
- Cortez and Mendoza Cardinal from The Leet World. Cortez was the leader of the Ochos Muertos terrorist group, Mendoza his second-in-command. When Cortez rejects Mendoza's plans to gain power and wealth, a furious Mendoza betrays brother, taking control of the Muertos and leaving Cortez blind. Years later, he hires the Domination Guy to kill Cortez, and when that fails, he concocts an elaborate plan to enter the House and finish his brother off.
Westheimer: I don't care about this feud of theirs. Probably goes back to "who did Mommy love more?"
- Played with when Team Dad Westheimer kills Mendoza in the final challenge, saving Cortez's life. However, Cortez (who had sworn to have his revenge on his brother for blinding him) is furious, and vows to avenge Mendoza's death.
Cortez and Mendoza: Me!
- MSF High Forum: Mel'lon and Rich.
- In one Neopian Times multi-chapter story, The Price of Faith, Lyth the evil, bitter Light Faerie frames her kind, sweet sister Pandora the Dark Faerie for stealing the Faerie Crystal from Fyora's staff, breaking it into seven pieces, and scattering it across Neopia.
- In New Vindicators, siblings are often at odds, its just that kind of series. Phobos and Deimos are twin brothers, and Deimos wants to be the one who kills Phobos, while Phobos' problems are less personal, and more because Deimos is a bad guy. In the European Academy, this pops up again, with the younger sibling being the evil one, wishing to make their older sibling suffer as much as possible, rather than outright killing them.
- The SCP Foundation has two entities registered as SCP-073 and SCP-076, respectively "Cain" and "Abel" (along with a SCP-336 "Lilith" who refuses to confirm or deny any relationship with them) with semi-complementary powers (Cain is an otherwise pleasant man with metal limbs who destroys any plant-based matter on contact, and anyone who hurts him receives the same injuries; Able is an eternally resurrecting and extremely deadly Implacable Man who became a Psycho for Hire for the SCP out of "boredom"). Able is still murderously angry at Cain (becoming violent at the sight of Cain's Oth, although he shouldn't be able to know what it is if God gave it to Cain after Able was killed...) They're both pretty much immortal. They've probably met again long before the SCP found them, and sometime after The Bible's story with them.
- Jeremy and Bran from Shadow of the Templar. While Jeremy still cares for Bran and wants him to reconcile with their father, Bran despises Jeremy for being a better thief than him and having stolen his father's attention from him despite being "only" a foster son. Whenever the two meet, it's always highly uncertain whether Bran will listen to Jeremy or kill him out of spite. It's even all but said that they had sexual relations in the past, which really makes their current relationship a helluva complicated one.
- Survival of the Fittest:
- Anthony and Lyn Laeil Burbank (although the gender tradition is bucked here).
- Another example would be Josee Trembley and Remy Kim of v4, who suffer from a Sibling Rivalry as a result of both siblings trying to win their mother's love as a result of both seeing themselves as The Unfavorite. Currently somewhat played with, as Josee actually wants either one of them to live to return home, and it looks like a team-up is in the works.
- The First Blood, a story in The Wanderer's Library, with the Anthropomorphic Personifications of Industry and Foresight as the brothers. It's left ambiguous which is which.
- The AlternateHistory.com timeline A More Personal Union has a cousins example in the case of Henri III of France and Ferdinand of Uceda. They utterly despise each other, and eagerly lead their countries into battle in the hopes of facing one another on the battlefield.
- In the episode "Gonna Getcha" of The Angry Beavers, the Beaver brothers watch a movie with a Cain and Abel plot. Daggett gets absolutely loaded with Paranoia Fuel.
- In Avatar: The Last Airbender, the royal family of the Fire Nation exhibits this with two sets of siblings. As above, in both cases the younger sib is the outright sociopath of the two. On one of the occasions where Azula outright attempts to kill Zuko, her brother, she shouts, "I'm about to celebrate becoming an only child!"
- In season 3, Sozin and Roku are revealed to have been as close as brothers in their youth. Then Roku went away to become the Avatar, and Sozin became Fire Lord and decided that what the world really needed was to be conquered by him. They'd grown apart rather, and Roku kept shutting Sozin down flat whenever he brought these ideas up. Eventually Roku violently halted an invasion of the Earth Kingdom, which Sozin interpreted as a permanent breach of their old friendship… and therefore betrayed Roku to his death during a volcanic eruption, leaving him free to launch his world conquest.
- And in The Legend of Korra, we have Amon/Noatak and Tarrlok. Neither's exactly good, but the younger, Tarrlok, is much closer to the heroes' side by the end of things than Amon is. Though unlike Azula and Zuko, at the end they really loved each other.
- Book 2 has Korra's father Tonraq and his brother Unalaq, the latter going to various lengths to eliminate the former and bring Korra to his side.
- The Professor Amadeus Sharpe and his older brother Mad Scientist Wilmer Sharpe aka Dr. Scarab, from Bionic Six.
- Boo Boom! The Long Way Home: Mario and his identical twin Giovanni are like this, since Mario is a member of the Italian resistance while Giovanni is allied with the Germans. In episode 7, Giovanni shows up with 2 German soldiers at Rossellini’s school, where an injured Mario is being nursed to health, to arrest his brother. However, he pulls a Heel–Face Turn when he realizes the Germans want to execute Mario, rather than just arrest him.
- Cree Lincoln and Numbuh 5 of Codename: Kids Next Door. Also, in Operation: Z.E.R.O., Numbuh Zero and Father.
- Wayne and Lucien Cramp of ''The Cramp Twins'.
- In "The Secret Origins of Darkwing Duck", Negaduck is said to be Darkwing's cousin, raised by Space Pirates.
- Defenders of the Earth has the Phantom and his brother Kurt.
- Parodied in the Dexter's Laboratory episode "Dollhouse Drama".
- In the Di-Gata Defenders backstory Nazmul was the Cain to Adar's Abel. Nazmul became corrupted by his power and created the megalith in order to seize all the power of the di-gata stones for himself.
- A mild-example in Ed and Sarah from Ed, Edd n Eddy. In The Movie, it's revealed in that Eddy had a big brother who always beat him up.
- The Diabolical Mastermind and Big Bad Phaeton and the Proud Warrior Race Guy and Defector from Decadence Marsala from Exo Squad. Although both were created artificially, they were from the same brood (and one of the earliest surviving, at that), so by Terran standards, they would have been brothers.
- To add to the fun, it's implied that Phaeton's villainy is an attempt to compensate for having betrayed Marsala during the First Neosapien War fifty years ago.
- A rather lighthearted example appears in Foster's Home for Imaginary Friends. The imaginary friends Imaginary Man and Nemesis (short for Nemesister) were created by a boy and his Bratty Half-Pint sister respectively—the sister created Nemesis just to bug her brother and Imaginary Man. Their feud continues after the now grown up siblings adopt Imaginary Man and Nemesis for their children. Ironically enough, the brother adopts Nemesis thinking she would be the perfect friend for his daughter and the sister adopts Imaginary Man thinking he would be the perfect friend for her son.
- Terrence and Mac can be viewed this way.
- Corey and Trina from Grojband, though most of the animosity comes from the latter.
- Ivanhoe: The King's Knight, as tradition dictates, features this between King Richard and Prince John.
- The title character from King Leonardo and His Short Subjects is the Abel to Itchy's Cain.
- Kong King Of The Apes has Kong's owner, Lukas, and his twin brother, Richard.
- Twister often has this relationship with his older brother Lars in Rocket Power.
- Ang, the Golden Dragon and his twin sister Ying, the Shadow Dragon (whose names sound suspiciously like Yang and Yin) in Legend Of The Dragon, at least until Ying's Heel–Face Turn.
- Masters of the Universe: Big Bad Skeletor was supposed to secretly have once been Keldor, the brother of King Randor (and thus Prince Adam/He-Man's uncle). This was never officially revealed in any canon but has been confirmed as the intended outcome of the original minicomics that had already begun to anviliciouslly hint at it when the toyline was axed. Skeletor's past as Keldor was depicted in He-Man and the Masters of the Universe (2002) and the backstory of he and Randor being half-brothers was discussed by the writers on a DVD commentary as being an additional reason for their more specific & personal animosity in that version.
- Megaman and Protoman are this in the Ruby-Spears Mega Man cartoon.
- My Little Pony: Friendship Is Magic:
- Princess Luna and Celestia form a rather complicated example. Luna got corrupted by an outside influence and when that was gone, Celestia immediately offered to return her to power.
- Also, in the episode "One Bad Apple", Babs Seed, who is the cousin of Apple Bloom, bullies the Cutie Mark Crusaders after she joins Diamond Tiara and Silver Spoon. However, when it turns out that she only did that out of fear of being bullied herself, she and the CMC make amends.
- The season 4 finale backstory has Tirek and Scorpan (originally from the G1 pilot episode Rescue at Midnight Castle) reimagined as two brothers. They aim to steal all the magic in Equestria until Scorpan makes friends with the ponies and turns against Tirek.
- Sensei Wu and Lord Garmadon in Ninjago are the series' Abel and Cain respectively. The former is the younger brother who grows to become a wise Old Master who acts as the mentor to the ninja. The latter is the older brother who slowly turns evil involuntarily after getting bitten by the Great Devourer, to the extent of becoming an Evil Overlord. Garmadon gets cleansed of evil after being defeated by Lloyd and turns good again.
- Over the Garden Wall has Adelaide, the Good Woman of the Woods, and her sister, the child-enslaving, turtle-eating Auntie Whispers. Adelaide is Faux Affably Evil, Auntie Whispers is Creepy Good.
- Spheros and Betrayus from Pac-Man and the Ghostly Adventures.
- Phineas and Ferb: Star Wars temporarily has this between Phineas and a Sithinatored Ferb.
- The relationship between Mojo Jojo and the girls in The Powerpuff Girls could easily be seen this way, especially after it's revealed that it was Mojo who caused the accidental addition of Chemical X into the perfect girl mixture. Interestingly enough, it's he who has a Villainous Breakdown when the truth is revealed…
- ReBoot's principal villains, Megabyte and Hexadecimal, are brother and sister, yet they are always trying to kill each other. When an incredulous Bob asks why, Hexadecimal casually explains that it's just "sibling rivalry."
- Thanks to a Retcon, Megabyte and Matrix fit this too. Matrix's dad, Wellman Matrix, is responsible for the "birth" of Megabyte. Megabyte even calls the nullified Wellman "father" so this makes Megabyte and Matrix brothers. Good thing Matrix doesn't know this since he has a problem with viruses.
- Robot and Monster has Robot and his Jerkass older brother Gart, who considers himself the Always Someone Better to Robot and will do anything to run afoul of him, such as buying the main duo's apartment and using his power to wildly lower and raise the temperature or creating a Pole-O team to go up against his, then using a blatantly false sob story to garner sympathy. Over the show's single season, Gart got hit by Laser-Guided Karma at least twice.
- In Shadow Raiders, Femur arranged for his brother to be locked away in the prison planet, a hellhole where the Cluster's worst war criminals were sent to, where he was subjected to horrific tortures and expected not to survive. Considering Femur had to bribe the soldiers that were dragging him away so he wouldn't be executed, Sternum had it coming for A: trying it and B: not using more loyal guards. And from what we later see, while Sternum is less Obviously Evil, he isn't actually any better.
- South Park:
- Eric Cartman and Scott Tenorman.
- Lemmiwinks and Wikileaks in "Bass to Mouth". In this case, it's the good brother killing the evil brother.
- In Superman: The Animated Series, Weather Wizard tries to kill his younger brother when he backs out of his mass-murdering plan.
- Teenage Mutant Ninja Turtles:
- In Teenage Mutant Ninja Turtles (1987) Shredder's younger brother, Lt. Kazuo Saki, is a member of the Tokyo Metropolitan Police Department; the two brothers despise each other, Kazuo rather embarrassed to have such a man as a sibling. (Note that in most continuities, "Saki" is actually Shredder's given name, his family name being "Oroku"—placed before the given name, as is done in Japan—making this version something of an error compared to other continuities.)
- In the 2003 series, adoptive brothers Hamato Yoshi and Yukio Mashimi become this when Mashimi, in a fit of jealousy, kills fellow adoptee and love triangle member Tang Shen. Afterwards, Yoshi kills Mashimi in revenge. (This is an adaptation of the story of Hamato Yoshi and Oroku Nagi from the original Turtles story, which led to quite the Cycle of Revenge when Nagi's younger brother Oroku Saki, who would later become the Shredder, murdered both Yoshi and Shen in vengeance for Yoshi killing Nagi.)
- Starfire and Blackfire of Teen Titans, who still look like a parallel of Queens Elizabeth and Mary Tudor, even though Glen Murakami admits that they watered down the much more intense rivalry of the original comics into a more kid-friendly, "I Dream of Jeannie/Bewitched kind of way." If you're even slightly familiar with the comics, you'll know what he's talking about◊.
- In the Thunder Cats 2011 episode "Between Brothers," Big Bad Mumm-Ra hopes to invoke this trope when Sibling Rivals Lion-O and Tygra travel to the Astral Plane, where they witness a scene from their youth that drives them to Sword Fight, Tygra using an astral copy of Lion-O's own Sword of Omens.
- Total Drama has its first sibling duo in Pahkitew Island with Amy (Cain) and Samey (Able).
- Transformers has Planet-sized, Transforming Mecha (that turn into planets) Physical Gods Primus and Unicron. Unicron is the Big Bad God of Evil Omnicidal Maniac seeking to destroy everything that isn't him. Primus is the Big Good who is completely loaded with BFGs and Wave Motion Guns seeking to thwart his brother. However, his trump card isn't any of that weaponry—it's the Transformers themselves. Unfortunately, they'd rather spend their time fighting each other.
- Kitty and her evil twin sister, Katty, from T.U.F.F. Puppy.
- Played with by The Venture Bros. where Thaddeus "Rusty" Venture eats his twin brother Jonas Venture, Jr while they were still fetuses. Jonas survives and later escapes, and attacks Thaddeus but gives up because he can't kill his own pathetic brother. Jonas finding his true calling as a heroic man of science quickly becomes a success financially, and with the ladies. It's basically implied that both would be successful if Thaddeus became a super villain, and arched his good brother.
- As the series progresses it's hard to say who is Cain and who is Abel—Jonas Jr. is certainly living up to their father's legend, but we start to see that Jonas Sr. had a pretty sleazy side.
- The Miser Brothers, Snow Miser and Heat Miser from The Year Without a Santa Claus, might be one of the best examples of this trope.
- The relationship between Goliath and his brother Stonecold in Gargoyles, although Stonecold was resurrected by the villains Demona and Xanatos and manipulated into hating Goliath.
- Not to the level of homicidal tendencies that we normally see on this trope (as is a show from The Disney Afternoon) but the relationship between Big Bad Duke Igthorn in Adventures of the Gummi Bears with his twin brother Victor is of total animosity as one is a vile traitor and the other is a heroic and loyal knight of the King.
- Baby sharks developing in the womb will fight and eat each other before they are born. Only two sharks end up being born, and that's only because there are two separate wombs.
- Invoked by the crown inheritance of the Assyrian Empire. As often case in polygamist cultures, the heir of the throne did not follow the primogeniture but rather every son of the king was a valid claimant. The usual way of arranging the inheritance was an all-out murder roulette where the sons murdered each other until only one was left. Although this practice was intended to guarantee that the ablest of the heirs would inherit the throne, it also meant that the Empire fell into anarchy and civil war until the new king had established himself. It eventually led into the collapse of the Empire.
- Pagan Min, the ninth king of the Konbaung Dynasty of Burma. When his father Tharrawaddy died in 1846, he was in line for the throne but his brothers opposed him. To ensure his right to the throne had no detractors, Pagan had his brothers killed.
- The Banquet of Nyköping 1317. The Swedish king Birger had invited his younger brothers, dukes Valdemar and Erik, to Castle Nyköping to feast at Christmas. After everyone had gotten drunk, king Birger imprisoned his brothers, put them in the oubliette of the castle and (so tradition says) threw the key into the nearby river. The dukes died from starvation. A large medieval key was found near the castle in 1847.
- The end of the Kingdom of Judah, as described in the Book of Kings and Chronicles in The Bible.
- Though it will never be proven, it's extremely likely that Cesare Borgia (son of Pope Alexander VI and then-Cardinal of Valencia) murdered or ordered the murder of his younger brother, Giovanni (Juan) Borgia, the Duke of Gandia. Juan was a hopelessly inept military commander, favored by his father; Cesare hated him and wanted his position. Being a magnificent bastard in more ways than one Cesare actually excelled at the job until his father died and ran out of funds.
- Similarly, chicks of several species birds of prey are known to murder their siblings while in nest.
- An interesting historical example is the murder of King Erik IV of Denmark by his brother, Abel. Chroniclers called the murderer "Abel by name, Cain by deeds."
- In 16th century Sweden, king Erik XIV starts behaving like he is insane and is deposed and imprisoned by his younger brother Johan after an insurrection. Johan makes himself king, while Erik's son and heir to the throne Erik Jr disappears abroad. Later king Johan has Erik Sr poisoned to death.
- Byzantine Emperor Isaakios II adored his brother Alexios and gave him many honors. Alexios repaid him by staging a coup, putting out his brother's eyes, imprisoning him, and crowning himself emperor as Alexios III. Isaakios' teenage son managed to escape his uncle's tyranny and showed back up on his doorstep with an army: The Fourth Crusade. Things went From Bad to Worse shortly thereafter, and Constantinople passed out of Byzantine hands for almost sixty years.
- Following the death of John VI of Portugal, his oldest son Pedro (then Emperor of Brazil) briefly succeeded to the throne. After abdicating in favor of his infant daughter Maria, Pedro's younger brother Miguel declared himself King, which led to the Portuguese Civil War (alternatively known as the War of the Two Brothers.) Six years later, Maria was returned to the throne, Miguel and his family were forced into exile, and Pedro died shortly after achieving victory.
- Invoked by Marie-Antoinette against her brother-in-law, Comte de Provence and future Louis XVIII, who stood idle as his brother Louis XVI was being murdered. According to José Cabanis' biography of the third brother, Charles X, Marie-Antoinette actually referred to the Comte de Provence as Caïn.
- The Minamoto brothers, Yoritomo and Yoshitsune, in feudal Japan.
- The Mughal dynasty had a lot of these. A prominent example is the murder of Prince Dara Shikoh, the King's oldest and favorite by Aurangazeb, a younger son.
- The Ptolemys of Egypt were great proponents of this. A rather famous one Cleopatra, was a big fan.
- The death of a Sultan of the Ottoman Empire regularly resulted in his male sons eliminating each other until only one legitimate heir was left. This was a result of Muslim marriage customs and inheritance law, which established that any son who could claim patrilineal descent (regardless if the mother was one of the Sultan's wives, concubines or slaves) had a legitimate claim to the throne. The practice was eventually discredited, with exile or imprisonment (in luxury conditions) becoming the preferred option for dealing with rival claimants.
- One of the greatest Emperor of Tang Dynasty, Emperor Tang Taizong is this trope. In an infamous incident known as the Xuánwǔmén zhī biàn (the Xuanwu Gate Incident), he ambushed his older brother Li Jiancheng (the crown prince) and his younger brother Li Yuanji. He killed his older brother personally, forced his father to make him crown prince only to make it proper for his father to surrender his throne to him just two months later.
- Oh ya, he also killed the sons of both Li Jiancheng and Li Yuanji, and made Li Yuanji's wife his concubine. That's just some badassery.
- And it's true that he's a noble Emperor.
- Li Jiancheng and Li Yuanji were also plotting against Li Shimin (brother number two). Li Jiancheng was jealous of his second brother because Li Shimin was more capable in almost every respect, and may have feared losing his crown prince position to him as a result. He recruited his third brother who was similarly jealous, and the two of them were in fact preparing an ambush/attack of their own at the very moment they themselves were ambushed. Or so it has been recorded. (History tending to be written by winners who become emperors…)
- Played definitely straight in the Wars of the Roses in 15th century England. It effectively meant the extinction of the Plantagenet dynasty and whole family line.
- The most specific example is George, Duke of Clarence. He is largely overlooked, with Richard being seen as the treacherous brother of Edward IV. However Clarence tried rebelling against Edward by claiming they were illegitimate meaning he was the rightful King, then helped a rebellion against Edward by the previous royal family, before switched sides again. Considering this, it isn't surprising Edward didn't trust him. Clarence continued to cause trouble for Edward, apparently thinking he wasn't getting enough influence, and was finally executed. Ironically enough, despite the Play "Richard III" having Richard be responsible for George's death, the earliest sources of this event claim one of the reasons Richard may have been opposed to the Woodvilles was because he blamed them for this.
- William the Conqueror's children. Henry, who may have (that is: almost certainly) had his other brother William Rufus murdered to gain the throne of England, staged a coup in Normandy against his eldest brother Robert, while the other was on crusade, and later imprisoned him.
- Roman Emperor Caracalla took this Up to Eleven. Simply having his younger brother and co-emperor Geta murdered was one thing, although having him die in their mother's armsnote was a nice touch. However he followed that up by submitting his brother's memory to damnatio memoriae, and having anyone even loosely associated with him purged - and by 'loosely', up to twenty thousand people were killed. Even four years later, he sacked the city of Alexandria for days because some actors performed a satire about the murder. He also banned the name Geta, which Ancient Rome being what it was wasn't very uncommon, so any will leaving money to anyone called Geta was rendered legally void, and anyone who had a slave named Geta had to change it. Why exactly the two brothers got on so badly isn't clear.
