9	* ''VideoGame/AgeOfWonders'' has Meandor and his half-sister [[TheHighQueen Julia]]. [[spoiler:They got better, even becoming allies in ''Shadow Magic''.]]
10	* The main villain of ''VideoGame/AkujiTheHeartless'' is Akuji's vengeful, power-hungry evil brother, who plots for Akuji's assassination during his wedding, and intends to start a clan war in Akuji's abscence.
11	* ''VideoGame/AssassinsCreedIVBlackFlag'' 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.
12	* The backstory in the ''Franchise/AssassinsCreed'' universe flavors the story of Cain and Abel itself for use in the franchise mythos. Their parents, Adam and Eve, were the first two Isu/Human hybrids to break free of the mind controls of their Isu masters. Cain killed Abel over one such device (fittingly called Apples of Eden), and the branding he got for his crime evolved into the symbol for the Templars.
13	* In ''VideoGame/BackyardSports'', 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.
14	* ''Franchise/BaldursGate'':
15	** ''VideoGame/BaldursGate'' plays this trope straight in the first game, then takes it to its logical extreme in ''VideoGame/BaldursGateIIThroneOfBhaal'', wherein five of the six required bosses are siblings of the player [[spoiler:and of Imoen, who may or may not be in the party]].
16	** ''VideoGame/BaldursGateIII'' potentially has this between [[spoiler:Orin and the Dark Urge. Both are Bhaalspawn, the former being Saverok's granddaughter and the Dark Urge given life from Bhaal's own blood, thus making them niece and uncle/aunt respectively. Although the Dark Urge was just as psychotic and bloodthirsty as Orin in the past, [[AmnesiacVillainJoinsTheHeroes their amnesia gives them the chance to fight off the urge while also opposing Orin and her fellow cultists]]. It also helps that Orin [[GreenEyedMonster personally despises the Dark Urge because they're Bhaal's favorite child]], and she betrayed them in the hopes of earning the god of murder's favor as their "replacement".]]
17	* Hinted at in ''VideoGame/TheBindingOfIsaac''. One of Isaac's playable "[[PaperThinDisguise siblings]]" is the literal Cain, and a power-up is a ghost baby named Abel. Whatever Isaac/Cain does, Abel does the opposite. If [[EverybodyIsJesusInPurgatory fan theory]] is to be believed, Cain and Abel represent [[spoiler:Isaac and Maggy, as he feels guilty for hating her while she was alive, and blames himself for her death.]]
18	** Another reference to Christian mythology, [[spoiler:Tainted Jacob]] is pursued by [[spoiler:Dark Esau]] that tries to kill you throughout the game. You have to avoid letting him touch you or get killed, or else you turn into [[OneHitPointWonder the Lost minus Holy Mantle]] for the rest of the floor. That being said, his attacks will damage other enemies and can wipe out early game enemies quickly.
19	* ''Franchise/BlazBlue'':
20	** A lot of drama 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 ArtifactOfDoom after said Church incident, Jin was chosen by the powers that be to be an "Antibody" to stop him. 2) His sword is an EvilWeapon and drives him to homicidal psychosis whenever he's around Ragna. Naturally, they can't stand each other, [[TeethClenchedTeamwork even when they're on the same side eventually.]]
21	** ''Central Fiction'' reveals this as the motive of [[spoiler: series villain Yuuki Terumi]]. He is [[UsefulNotes/{{Shinto}} Susanooh]], jealous and spiteful brother of [[TopGod Amaterasu]].
22	* In ''VideoGame/{{Boktai}}'', Django later finds out [[TheRival Sabata]] is his ([[spoiler:initially]]) evil, half-brother.
23	* ''VideoGame/{{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.
24	** ''VideoGame/Borderlands3'': [[AnIcePerson Aurelia]] [[VideoGame/BorderlandsThePreSequel Hammerlock's]] relationship with her brother, Sir Alistair Hammerlock, has devolved from her being a [[BigBrotherBully bullying big sister]], into this. As a child, [[KickTheDog she drowned a pet lizard Hammerlock took care of (it was originally hers)]] [[{{Gaslighting}} in a way that made him believe that it was his own fault.]] In the game proper, she allies with the Children of the Vault and [[BigBadDuumvirate the Calypso Twins]]. She sells her brother out to them and attempts to forcefully take over the Jakobs corporation as their new CEO. [[ForTheEvulz All of this is done for little other purpose than to relish in Alistair's suffering.]] [[spoiler: Hammerlock, being the NiceGuy he is, tries to peacefully talk things out with her one last time; Aurelia's response is to shoot him in the gut and freeze both him ''and'' his [[StraightGay boyfriend]] Wainwright Jakobs solid and they both would have died had the [[PlayerCharacter Vault Hunter]] not intervened.]]
25	** Taken to [[ExaggeratedTrope the extreme]] with Katagawa Jr. [[spoiler: He ''[[MoralEventHorizon murders all of his siblings at a party he was hosting,]]'' [[EvilIsPetty just so HE could be the new CEO of the Maliwan corporation.]] One of his sisters, Naoko, [[SoleSurvivor managed to escape, though.]] She's forced into hiding in Promethea, and is left with a burning hatred toward her utter monster of a brother.]]
26	* The ending of ''VideoGame/BreathOfFireIII'' {{reveal}}s that [[spoiler:Bleu/Deis, protector of the Dragons]], is actually the [[BigBad Goddess Myria's]] sister.
27	* ''VideoGame/CapellasPromise'' 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. [[spoiler: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.]]
28	* ''VideoGame/CelestialHearts'': Helen is an angel [[spoiler:and the sister of Lilth. At the start of the game, Lilith drained Helen of most of her energy in order to gain the power to destroy the world. The only reason she doesn't immediately destroy the world is because she wants to give Helen a false sense of hope in stopping her. Right before the final battle, Lilith reveals that she's jealous of how Helen was born with free will and was allowed to have a fulfilling life while the former was made into a puppet of an evil deity]].
29	* In ''VideoGame/CliveBarkersUndying'', 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.
30	** There are also Bethany and Aaron, twins who utterly despised one another and were in constant rivalry. Bethany won, by [[spoiler: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]].
31	* In ''VideoGame/CommandAndConquerRenegade'', the series-wide BigBad Kane is hinted to be the biblical Cain, as the Temple of Nod in Cairo has Abel's tomb in its catacombs.
32	* Aku Aku and Uka Uka in the ''VideoGame/CrashBandicoot'' series, being the BigGood who rallies Crash and the BigBad who has Neo Cortex under his thumb, respectively.
33	* King Noob and [[spoiler:Nebulous Noob]] in VideoGame/{{The Day The Noobs Took Over Roblox 3}}. Both still care for each other, but when their parents were [[spoiler:killed for their noobanium]] caused both of them to radically change. While King Noob simply only wanted to conquer Roblox, [[spoiler:Nebulous]] straight up ''destroyed'' it.
34	* Kasumi and Ayane of ''VideoGame/DeadOrAlive''. They were [[WeUsedToBeFriends best friends as children]], especially given Ayane's [[AllOfTheOtherReindeer status as a village pariah]]. When they discover that they are [[LukeIAmYourFather half-sisters]] and Ayane is the [[ChildByRape 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 [[AntiHero Anti-Heroic]], and as of the ending of [[spoiler:''Dead or Alive 5'']], they seem to have reconciled.
35	* Dante and Vergil of ''VideoGame/DevilMayCry''. 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 [[VideoGame/DMCDevilMayCry new game]], it is more a question on whether the Nephilim should let humans decide their own fates (Dante) or rule over them (Vergil). ''VideoGame/DevilMayCry5'' describes their relationship quite well [[spoiler:right before defying the trope, as Nero already hates himself for losing his childhood friend Credo and isn't in the mood to let his father or uncle die]].
36	-->''"A brotherhood defined by hatred and grudging respect. A rivalry for the ages. Vergil and Dante clashed... all their grievances, their enmity, their reasons to fight, focused into one decisive battle. [[spoiler:But this would not be their end... Nero, having found his own reasons to fight, comes between his father and uncle. [[DefiedTrope There will be no fratricide this day]]]]."''
37	* It's quite literal in ''VideoGame/DevilSurvivor'', where [[spoiler: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 StealthMentor 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 SecretTestOfCharacter to see if the protagonist has the will to enslave the demons]].
38	* This trope is what led to [[spoiler: Fuuka]]'s murder in ''VideoGame/{{Disgaea 4\| A Promise Unforgotten}}''.
39	* One of the most iconic sibling rivalries comes in ''VideoGame/DoubleDragon'', in which Billy and Jimmy fight each other at the end. The NES version takes it one step further, as Jimmy is the leader of the Black Warriors, making him the Cain to Billy's Abel by default.
40	* This comes up several times in ''VideoGame/DragonAgeII''. Near the end of Act I, [[spoiler:Bartrand]] succumbs to greed [[spoiler:and the lyrium idol's curse]] and tries to kill [[spoiler:Varric]] to avoid sharing the wealth. [[spoiler: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. [[spoiler: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 [[spoiler:Bethany if she joined the Circle]]. Oddly enough, [[spoiler: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 [[spoiler:Fenris]] and his sister [[spoiler:Varania]] after she [[spoiler: sells him out to his former master so that she can become a mage apprentice]]. If the player does not interfere, [[spoiler:Fenris will kill her]].
41	* ''Franchise/TheElderScrolls'':
42	** In the series' lore, Anu and Padomay are the anthropomorphized primordial forces of [[OrderVersusChaos "stasis/order/light" and "change/chaos/darkness"]], respectively. They are usually referred to as brothers, twins to be specific. [[CreationMyth Their interplay in the great "Void" led to Nir, "creation"]]. Nir loved Anu, [[DrivenByEnvy 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. [[TakingYouWithMe Anu pulled Padomay outside of time itself]], ending his threat to creation. From the blood of Anu and Padomay came the [[OurGodsAreDifferent 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.)
43	** ''[[VideoGame/TheElderScrollsIIIMorrowind Morrowind]]'':
44	*** The Dren brothers -- Vedam Dren, the noble duke of Vvardenfell, and Orvas Dren, the leader of the xenophobic criminal organization, [[TheSyndicate the Camonna Tong.]] Vedam doesn't ''want'' his brother killed, but isn't overly angry if it comes to that, while Orvas… [[spoiler: is planning to murder his brother, which you can use to blackmail him if you find the implicating letter]].
45	*** Sjoring Hard-Heart and Radd Hard-Heart. Sjoring is the leader of the Fighter's Guild [[spoiler: and very much in the pocket of the aforementioned Camonna Tong]] while the other is an honorable officer of the [[BadassArmy Imperial Legion]].
46	** ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]'': Alduin and [[spoiler: Parthunaax]], Alduin is the primary antagonist of the game who is the Firstborn of Akatosh and leader of the dragons who in the ancient past decided to conquer the world and have mortals worship him or enslaved. [[spoiler: Parthunaax, his younger brother]] chose to side with the mortals and aided them in defeating Alduin, [[spoiler: becoming the leader of the greybeards and living atop the highest peak in Tamriel for a millennia meditating on the way of the voice in order to atone for his former crimes as Alduin’s Lieutenant,]] becoming an ally to the last Dragonborn and helping defeat Alduin when he returned.
47	* WesternAnimation/MickeyMouse and his older [[LongLostRelative half-brother]] WesternAnimation/OswaldTheLuckyRabbit are this in ''VideoGame/EpicMickey''.
48	* ''VideoGame/EasternExorcist'' has the sworn brothers variety. The player hero, Lu Yun-chuan, is the titular exorcist and on the side of good, but his foster sibling, Zhang Huai-zhou, is a traitor secretly aligned with the forces of evil for more power.
49	* ''VideoGame/ExitFate'' also contains two such siblings (in this case, twins of opposite genders): [[spoiler:Brunhild and Daniel]]. Clearly, SCF likes putting siblings at odds with each other…
50	* The premise of ''VideoGame/FableIII''. BigBad 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.
51	* In ''[[VideoGame/FirstEncounterAssaultRecon FEAR]]'', it's explicitly canon that [[spoiler: Alma (the homicidal female ghost) is the Point Man's mother, Paxton Fettel (TheDragon) is the Point Man's brother, and the MadScientist 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 SuperSoldiers]]. All in all, they're a BigScrewedUpFamily.
52	* ''VideoGame/FearEffect: Retro Helix''. [[spoiler: 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]].
53	* In ''VideoGame/TheFeebleFiles'', Feeble's brother has no issues setting his brother up to be erased by the authorities if it means finally getting a promotion.
54	* In the ''Franchise/FinalFantasy'' series:
55	** In ''VideoGame/FinalFantasyIV'':
56	*** This happens to no end to Cecil. His best friend and comrade in arms who [[RivalTurnedEvil betrays him]] is actually 'named" Cain. (Kain in the original North American release, because I guess it was too obvious ''otherwise?''). [[spoiler:The second time it was revealed that BigBad Golbez was his ''actual'' brother.]] Of course, it was revealed in the end that [[spoiler: both were actually just being mind-controlled by TheManBehindTheMan]]. 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.
57	*** In the DS version, it is revealed that [[spoiler: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 TheReveal, now you know]]. [[spoiler:To be fair to Golbez, he pretty much makes up for being the Cain in the Sequel when he performs a HeroicSacrifice. Even in the CrisisCrossOver ''VideoGame/DissidiaFinalFantasy'' he ends up being the game's StealthMentor.]]
58	** [[spoiler:[[BigBad Kuja]] and [[TheHero Zidane]]]] of ''VideoGame/FinalFantasyIX''. They also have a [[CainAndAbelAndSeth Seth]] in [[spoiler: their sister [[MrExposition Mikoto]].]]
59	** Gabranth and Basch in ''VideoGame/FinalFantasyXII''. Interestingly, this is reflected in gameplay: both times Gabranth is fought as a boss, his A.I. will target Basch more than any other party member.
60	** In ''VideoGame/FinalFantasyXVI'':
61	*** Narrowly subverted early on. Clive, who has been enslaved by the Holy Empire of Sanbreque, is ordered to assassinate Shiva's Dominant. It isn't until he's incapacitated her in combat that he realizes that the Dominant is actually Jill Warrick, his long-lost foster sister. [[BigBrotherInstinct Fortunately, Clive chooses that moment to go rogue rather than murder possibly the only remaining link to his old life.]]
62	*** After defeating Garuda, Clive learns that [[spoiler:he himself is Ifrit's Dominant, and concludes that he killed his own brother Joshua]]. [[spoiler:Of course, it's subverted when Joshua turns up very much not dead.]]
63	*** By the time the heroes reach the Crystalline Dominion, [[spoiler:Imperial prince Dion Lesage has staged a coup and intends to assassinate the emperor, his half-brother Olivier (and his WickedStepmother Anabella Lesage for good measure). He is tricked into killing his father, goes berserk, has to be subdued by his maternal stepbrothers Clive and Joshua, and in the end does manage to kill Olivier.]]
64	** Interestingly, ''VideoGame/DissidiaFinalFantasy'' reveals a hostile sibling relationship between [[spoiler: Chaos and [[VideoGame/FinalFantasyI the Warrior of Light]]]]. The twist being that neither knows of the connection.
65	* Tons of examples in the ''Franchise/FireEmblem'' franchise.
66	** In ''VideoGame/FireEmblemShadowDragonAndTheBladeOfLight'', 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 ''VideoGame/FireEmblemMysteryOfTheEmblem'' and ''VideoGame/TokyoMirageSessionsFE'', and then only because IHaveYourWife and BrainwashedAndCrazy are respectively in play.
67	** ''VideoGame/FireEmblemGenealogyOfTheHolyWar'': First the brothers of RebelPrince Jamke are brutish pawns of a cult. Afterwards comes Andrey, the younger brother of Briggid, [[SelfMadeOrphan who killed his own father]] [[TheEvilPrince to get the title of Duke]]. There's also Danann, the evil brother of [[MadScientistsBeautifulDaughter Mad Dictator's Handsome Son]] Lex. Similarly, MadScientistsBeautifulDaughter Tailtiu's brother Bloom [[OverlordJr took after their father]]. At the end of the WhamEpisode, Arvis betrays and orders the executions of his own half-brother Azelle ([[spoiler:and all of your other guys for good measure]]). Only one of the pair of Luchar and Lucharba can be recruited, making the non-recruited one turn against his brother. Near the end, Brian, the [[YoungerThanTheyLook emancipated]] but [[TheBrute super]] [[MusclesAreMeaningless strong]] brother of Luchar/Lucharba, shows up for revenge. Prince Julius is the inbred vassal of [[SealedEvilInACan Loptous]] who (barring CherryTapping) needs to be killed with Naga and wields dark magic, and he comes into conflict with both his twin sister Princess Julia who is good [[spoiler:when she is not brainwashed]] and has the Naga light magic and his maternal half-brother [[spoiler:Seliph]]. Yes, ''Genealogy of the Holy War'' IS creepy.
68	** In ''VideoGame/FireEmblemThracia776'', Olwen betrays the child-killing Loptr Empire and comes into conflict with her brother Reinhardt in the process.
69	** In ''VideoGame/FireEmblemTheBindingBlade'', there's [[StrawNihilist 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.
70	** ''VideoGame/FireEmblemPathOfRadiance'''s Mad King Ashnard fits, what with killing all of his other siblings in order to take the Daein throne and all.
71	** In ''VideoGame/FireEmblemFates'':
72	*** 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 SadisticChoice. 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.
73	*** According to support conversations, the surviving Nohrian royal siblings are the only Abels of their extended family in King Garon's DecadentCourt. There used to be a ''lot'' more kids and consorts in the palace.
74	** In ''VideoGame/FireEmblemThreeHouses'':
75	*** Miklan is the Cain to Sylvain's Abel since Sylvain was born with a Crest (and thus had the right to inherit leadership of their family), while Miklan did not. Miklan has always hated Sylvain for having what he always wanted, and the feeling is mutual due to [[BigBrotherBully how much shit Miklan put Sylvain through during their childhood]]; [[spoiler:after Miklan turns evil, Sylvain isn't all that bothered about having to kill him. After Miklan's transformation into a Beast and his subsequent death, however, Sylvain takes some time to reevaluate his feelings and admits while he still can't forgive his brother, [[SympathyForTheDevil he can at least empathize with what led him down his path]]]].
76	*** [[spoiler:Edelgard]] and [[spoiler:Dimitri]] are stepsiblings, but when the former's actions in the name of their ideals come to light, they have a ''vicious'' falling out and the latter spends all of Part II hounding for their blood.
77	*** Mercedes ends up on the opposite side of a war with her half-brother Emile [[spoiler:a.k.a. the Death Knight]]. There is one specific scenario that prevents them from coming into conflict, though: [[spoiler:recruit Mercedes to the Black Eagles and side with Edelgard at the Chapter 11 route split]].
78	*** Gilbert's brother Baron Dominic is forced into subservience to [[spoiler:the Adrestian Empire]] in Part II, and the two cross blades in Gilbert's paralogue.
79	*** In the backstory, [[spoiler:Dimitri's EvilUncle, Grand Duke Rufus, was a part of the conspiracy that killed his brother, the king.]]
80	*** In Claude's backstory, he was abused by his [[spoiler:Almyran]] half-brothers. In ''VideoGame/FireEmblemWarriorsThreeHopes'', one of them (Shahid) actually attacks Leicester and serves as a recurring personal enemy to Claude.
81	* ''VideoGame/{{Galerians}}'': Rion and, uh… Cain. The rivalry is entirely one-sided on Cain's part, since [[spoiler:Rion has no way of knowing that a backup Rion clone was made specifically to kill him.]]
82	* Kratos actually has several of these in ''VideoGame/GodOfWar'', [[spoiler: 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 WellDoneSonGuy who hopes to surpass Kratos, and Athena, who plays the role of ally, reluctant enemy, ally again, and finally BitchInSheepsClothing]].
83	* In ''VideoGame/GrandiaII'' the main character must fight his older, more skilled, possessed brother.
84	* In ''VideoGame/{{Harvestella}}'' [[spoiler: Gaia]] is the Cain and tries to kill the party, cynically believing humanity is doomed to destruction and squandering every opportunity given them. [[spoiler:[=ReGaia=]]] is the Abel that helps the party, being optimistic about humanity's future and is confident that they can keep improving over time.
85	* Some examples in the ''VideoGame/HeroesOfMightAndMagic'' series:
86	** The fathers of Morglin and Ragnar in [[AllThereInTheManual 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 [[UnreliableNarrator unreliable narrations]] that he, Morglin, had attempted to have Ragnar killed too.
87	** Roland and Archibald Ironfist. Though, ultimately, neither brother is willing to go all the way: in their respective endings in Heroes II, Archibald gets TakenForGranite 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.
88	* In ''VideoGame/HiFiRush'', this is eventually revealed to be a major plot point: [[spoiler:Peppermint is Roxanne Vandelay's daughter, making Kale, the BigBad, her older brother. Peppermint directly opposes Kale's takeover of Vandelay Technologies and leads a resistance to expose his schemes while trying to discover why Roxanne disappeared, while Kale uses propaganda to {{unperson}} Peppermint and attempts to kill her for interfering with him]].
89	* [[spoiler:Ros]] and [[spoiler:Lazarus]] in ''VideoGame/IMissTheSunrise''.
90	* ''VideoGame/JadeEmpire'': Emperor Sun Kai and your mentor Sun Li. [[spoiler: 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 YouHaveOutlivedYourUsefulness.]]
91	* ''VideoGame/KameoElementsOfPower'': Kalus becomes this to Kameo, who gets blinded by rage and jealousy when the later becomes heir to the throne. As the former thought it rightfully belonged to her, she forms a BigBadDuumvirate with the troll leader, King Thorn, to take it back by force. Though it turns out [[spoiler:Kameo is actually adopted.]]
92	* In ''VideoGame/KidIcarus1986'', 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 [[DarkIsEvil 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 [[DidYouJustPunchOutCthulhu finished]] the [[KillTheGod job.]]
93	* ''VideoGame/KingdomHeartsBirthBySleep'' actually turned the relationship between WesternAnimation/{{Cinderella}} and her evil step-sisters into this. While they were very cruel to her in the films, [[spoiler: they outright tried to [[MoralEventHorizon murder her]] out of [[ThePowerOfHate hatred]] with an Unversed in the game, which [[HoistByHisOwnPetard backfired on them spectacularly]]]].
94	* ''VideoGame/KnightBewitched'': Bjalla and Strasza are siblings on opposite sides of the conflict. Bjalla is a red dragon that loves Typhus, being his concubine, and sides with him in killing humankind, Strasza is a blue dragon that leads the remains of dragon society and is trying to take Typhus down. [[spoiler:Bjalla seems to be under some sort of control, though, as she thanks you for defeating her.]]
95	* ''VideoGame/LastScenario'' has [[spoiler: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.
96	* ''VideoGame/LeagueOfLegends'' has several pairs.
97	** Kayle and Morgana are estranged joint-holders of the title of Aspect of Justice, each thinking the other is misguided at best and evil at worst.
98	** Nasus and Renekton were heroic brothers until Renekton attempted SealedEvilInADuel on a maddened Xerath and emerged centuries later with nothing but an insane hatred for his brother.
99	** Yone was Yasuo's only defender until he believed (false) accusations that his brother was a murderer; he challenged Yasuo to a duel of honor and Yasuo was forced to cut him down.
100	** Vi and Jinx. Mortal enemies on opposite sides of the law, Vi a CowboyCop and Jinx a wacko anarchist bent on destruction, and also sisters.
101	* There's a sidequest in the first ''Franchise/MassEffect'' game in which Nassana Dantius, an asari diplomat on the Citadel, asks you to rescue her sister, Dahlia, from slavers. [[spoiler: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 [[FridgeBrilliance actually kind]] [[HilariousInHindsight of funny]] due to the fact that her [[Creator/GreyDelisle voice actress]] voiced [[WesternAnimation/AvatarTheLastAirbender Azula.]]
102	** The second game has DLC where Shepard learns that a researcher has [[spoiler:forced his own brother into cruel, psychologically traumatizing experiments]]. [[EvenEvilHasStandards Even Renegade Shepard thinks this is not legit]], and the paragon ending includes a ''[[GoodIsNotSoft paragon]]'' interrupt of {{Pistol Whip}}ping the culprit!
103	* The Snake Brothers (okay, "Les Enfants Terribles", strictly) in the ''VideoGame/MetalGear'' series. Liquid seems to enjoy the rivalry immensely. Perhaps a little [[BrotherSisterIncest too]] [[ScrewYourself much]].
104	** It's no coincidence that [[spoiler: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."]]
105	* The trailers for ''VideoGame/ModernWarfare2'' 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…'' [[{{Revenge}} but they will.]]''
106	* ''Franchise/MortalKombat'':
107	** 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.
108	** In the first two timelines, Mileena is an EvilTwin knockoff to Kitana and wants to kill her. Averted in the new timeline ruled by Liu Kang, as Mileena has genuinely gotten AdaptationalHeroism, in addition to being actually Kitana's biological sister and is in better terms with her, albeit Mileena is still HotBlooded, and is infected with the Tarkat disease which causes her quite a lot of issues.
109	** Also in ''VideoGame/MortalKombat1'', again between Bi-Han (again, as Sub-Zero) and Kuai Liang (who now takes the mantle of Scorpion), this time because [[spoiler:Bi-Han betrays and turns against Kuai Liang, cementing the former's FaceHeelTurn as well.]]
110	* In ''VideoGame/Mother3'', [[spoiler: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]].
111	* ''VideoGame/TheNeverhood'': [[spoiler:Klogg and Klaymen are both creations of Hoborg, and are technically his children by extension. The villainous Klogg attempts to kill his little brother Klaymen across the story. (Admittedly, Klogg's evilness came about before Klaymen was even created.)]]
112	* Mugen and Hikari from ''VideoGame/OctopathTravelerII''. Their father wants Hikari to be king, since he's sick of Ku's warmongering, and Hikari is much kinder and more peaceful than Mugen (which also makes Hikari more popular with Ku's commonfolk). As a result, Mugen [[{{Patricide}} kills King Jigo]], takes the throne, drives Hikari out of Ku, and winds up as Hikari's final boss.
113	* The Shimada brothers Hanzo and Genji from ''VideoGame/{{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 CyberNinja, 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.
114	* ''VideoGame/PeacemakerGloriousPrincess'': After killing King Dawn, Prince Darknight seeks to kill his sister Princess Gloria in order to claim the Unifier sword and legitimize his claim to the throne.
115	* The final bosses for ''VideoGame/RiskOfRain'' and ''VideoGame/RiskOfRain2'', Providence and Mithrix respectably, serve these roles toward each other. Providence is a WellIntentionedExtremist who wants to preserve life at any cost, while Mithrix is a MadScientist who loves to create constructs and has a LackOfEmpathy for weaker beings. When Mithrix built a teleporter one-way trip to get off the planet they were born on, Providence allowed him to step in first before destroying it, trapping him on the moon as Mithrix eventually [[SanitySlippage goes mad from isolation and envy]] and swearing revenge. They're both eventually and separately slain by the player.
116	* In ''VideoGame/SagaFrontier,'' there are Blue and Rouge, twins who're told to kill the other after mastering as much magic as possible. [[spoiler: Who wins is irrelevant since they turn out to be the same person, SplitAtBirth.]]
117	* The obscure PC game ''VideoGame/SanityAikensArtifact'' feature such a storyline with someone named Cain as the protagonist and the so-called foster brother Abel as the final boss.
118	* ''VideoGame/{{Scathe}}'' zig-zags this trope where the Supreme Creator who grants you life was supposedly the BigGood, while his brother, Sacrilegious, is the BigBad, which you're tasked to destroy. While the BadEnding has Sacrilegious taking over your mind, you get two further endings, either submit to the Supreme Creator (who then goes into a fit of EvilGloating before the credits role) or, should you collect enough runes, instead [[TurnedAgainstTheirMasters betray the Creator]] and take over his place, as the GoldenEnding. It remains unconfirmed between the Creator and Sacrilegious, which is the Cain and which the Abel.
119	* ''VideoGame/SenranKagura'' has Hyoki, who hates her sister Leo to the extent she forms Senki Shu, with the intention of harnessing the power of the Yoma to destroy the shinobi principle.
120	* In ''VideoGame/SoulcaliburV'', Sophitia's children Patroclus and Pyrrha are driven to this [[spoiler: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]].
121	** ''[[VideoGame/SoulSeries Soulcalibur IV]]'': Sophitia becomes the Cain to Cassandra's Abel, but not willingly because she has been ForcedIntoEvil.
122	* In ''VideoGame/{{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.
123	* In the ''Knights of the Fallen Empire'' expansion of ''VideoGame/StarWarsTheOldRepublic'', Arcann killed his twin brother Thexan when he lashed out at his father [[GodEmperor Emperor Valkorian]] and Thexan tried to stop him. It was this act however that led to Valkorian acknowledging Arcann has his heir. [[spoiler:His younger sister Vaylin, whom Valkorion drove AxCrazy in efforts to control her Force powers, pulls a {{Starscream}} on him in turn at the climax of ''Fallen Empire'', forcing him to flee into exile; he can be recruited by the PC at the start of ''Knights of the Eternal Throne''.]]
124	* ''VideoGame/StellaGlow'' has Marie as the Abel to her sister Eve, helping the party to defeat her and believing in the best of humanity. Eve tries to kill humanity and spread despair throughout rhe world, even trying to corrupt her sister into despair. [[spoiler:Justified as Marie and Eve were created from humanity's positive and negative experiences, respectively, and if the player wishes they can have Eve make a HeelFaceTurn]].
125	* ''VideoGame/StreetFighterIV''. 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 [[spoiler: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 WordOfGod, 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 [[spoiler:Gouken]].
126	* [[ZigZaggingTrope Zigzagged]] in ''VideoGame/TalesOfTheAbyss''. 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}}. [[spoiler: Then Van is revealed as the BigBad 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 [[InvertedTrope heroic Cain going up against a villainous Abel]]. Then, by the end of the game, Tear has experienced CharacterDevelopment 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.]]
127	* Redmond and Blutarch Mann from ''VideoGame/TeamFortress2'', to the point that not even death can stop the rivalry between them; when they're both killed by their [[LongLostRelative 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.
128	* In the fashion of the ''Anime/TekkamanBlade'' example, ''VideoGame/SuperRobotWarsCompact3'' 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 on the enemy's side. Subverted because Fernando and Altis are not outright evil, they're just Folka's enemies on circumstances.
129	** 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 ([[SadisticChoice long story]]), whom it's suggested Rai was in love with.
130	** In ''VideoGame/SuperRobotWarsNEO'', Amane Inaba [[spoiler: when possessed by Larva]] is the Cain and Kakeru Inaba is the Abel.
131	* ''VideoGame/{{Tekken}}'' has Nina and Anna Williams.
132	** Kazuya Mishima and Lee Chaolan fit this trope as well since technically [[spoiler: Lee is Heihachi's son through adoption]].
133	** Likewise with Kazuya and Lars, since [[spoiler:Lars is the son of Heihachi and a Swedish mistress]].
134	* Jacky and Sarah Bryant from ''VideoGame/VirtuaFighter'' 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, [[UnwittingPawn not knowing this is all part of J6's plot]].
135	* In the ''VideoGame/{{Warcraft}}'' universe, [[OurElvesAreDifferent night elf]] twin brothers Illidan and Malfurion Stormrage are Cain & Abel respectively. Illidan became a demon literally due to his [[spoiler: 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.
136	** 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).
137	** In the {{backstory}}, [[ComicBook/{{Ashbringer}} Darion (Abel) and Renault (Cain) Mograine]] become this, fueled by their father's perceived ParentalFavoritism toward Darion. Though Renault [[SelfMadeOrphan turned his ire on Dad first]].
138	** In ''VideoGame/WorldOfWarcraft'', 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.
139	** 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.
140	** 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.''
141	* The ridiculously [[RatedMForMoney gory]] and [[FakeDifficulty difficult]] adventure game ''VideoGame/Waxworks1992'' 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 [[SetRightWhatOnceWentWrong 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 UsefulNotes/JackTheRipper, a necromancer who looks far older than his good twin, and a [[TheVirus human/fungus mutant]] who doesn't even resemble a human anymore. That is, until TheReveal that [[spoiler:[[TomatoInTheMirror you were the evil twin all along]]]].
142	* ''VideoGame/{{Xenogears}}'' has a character named Abel, and a character named Cain. Cain was (indirectly) the one who killed Abel. [[FauxSymbolism That's about where the similarities end.]]
