History Main / SiblingRivalry

* ''WesternAnimation/{{Amphibia}}: 10-year-old Sprig and 5-year-old Polly have quite a rivalry. Their personalities are [[SiblingYinYang nearly opposites]], with Sprig being easygoing and hyperactive, while Polly is aggressive yet more responsible. It comes to head in "[[Recap/AmphibiaS1E23CivilWart Civil Wart]]", when the ''entire town'' takes the side of one sibling or the other in a ShipToShipCombat. They resolve to support each other from then on, but the rivalry doesn't disappear.

* ''VideoGame/CardCityNights2'': Discusses ''VideoGame/PsyCard'' characters in their FlavorText:
--> '''Ur:''' As the King of PsyCard he has many rivals, including his jealous sister Hedvig. He tends to cause electrical damage at tournaments.\\

* ''WesternAnimation/SummerMemories'': Jason and Tim's antagonistic relationship is a major part of the series, on part due to both suffering massive insecurities they tend to vent out on each other. While the show initially presents Jason as the "good" sibling and Tim as the "bad" one, the UnreliableNarrator element core to the series eventually makes it clear this is only how Jason remembers it, and [[spoiler:we see in "That Ain't The Way I See It" that Tim perceives it oppositely from Jason.]]

* In ''Literature/TheBridgeOfClay'' Rory and Henry Dunbar (the second and the third of five sons) always fight over everything. And since they are forced to share a bedroom for several years, many of these arguments and fights are over one brother's stuff left lying on the other brother's side of the room.

* Throughout his memoir ''Spare'', [[UsefulNotes/TheBritishRoyalFamily Prince Harry]] revealed that contrary to close-knit relationship frequently promoted by the media for decades, his relationship with his brother William was far more akin to this, possibly to the point of BigBrotherBully, even explicitly describing him as "my beloved brother, my archnemesis". Harry resented being relentlessly treated as TheUnfavorite simply because he was born second while William resented (a) that Harry got to serve on the front lines in Afghanistan (as heir, he wasn't allowed to place himself in such danger), (b) Harry's founding of the [[https://en.m.wikipedia.org/wiki/Invictus_Games Invictus Games]], to the point of trying to interfere with it--Harry outright describes William's jealousy over this as this trope, and (c) that Harry got to wear his beard for his wedding,[[note]] soldiers are forbidden to wear a beard while in uniform, but Harry had asked his grandmother for permission to keep his [[/note]] to the point of pettily demanding that Harry shave it, even threatening to forcibly do it, all because he hadn't been allowed to keep his, and even hit him during an argument. Despite all this, it's still clear that as stated, Harry loves his brother dearly, with the two of them even exchanging an AnguishedDeclarationOfLove in the midst of yet another argument, perfectly demonstrating the dual nature of their relationship.

* ''Literature/{{Siren}}'': Vanessa's late sister Justine was a popular, outgoing risk-taker. Vanessa always thought that was just her personality, but after Justine's death, she learns that Justine was jealous of all the attention Vanessa got without even trying [[spoiler:because of her siren ancestry]], and felt like she had to go to great lengths to get anyone to notice her.

Naturally, the closer the siblings are in age, and if the siblings are of the same gender, the more intense the rivalry is likely to be, and the more likely one of the siblings will feel AlwaysSecondBest. Extreme cases may result in CantCatchUp, especially if an AloofBigBrother is involved. If the parents take sides one of the rivals is bound to become TheUnfavorite. If the strife is due to the siblings only sharing one common parent, it may lead to HalfSiblingAngst or BastardAngst. When it spills over into romantic affairs with two siblings pursuing the same LoveInterest, it can become a SiblingTriangle.

** The Harbaugh brothers, who were both NFL coaches in the early 2010s (Jim is now back coaching in UsefulNotes/{{colleg|iateAmericanFootball}}e at his alma mater of [[UsefulNotes/CollegiateAmericanFootballPower5Conferences Michigan]]), are another American football example. They have coached against each other twice, on Thanksgiving Day in 2011 and in Super Bowl XLVII in February 2013 (nicknamed the "Harbaugh Bowl" or "[=HarBowl=]" for obvious reasons). John's Baltimore Ravens defeated Jim's San Francisco 49ers both times.

* Music/TheBlackCrowes were lead by brothers Chris and Rich Robinson. Stories about of band rehearsals degenerating into physical brawls between the two, only to stop suddenly when they feel they've figured out the music. They did make a point of never letting their animosity spill over into their live act (unlike Oasis), as they felt it was disrespectful to the fans.

* ''Series/TheCompnayYouKeep'': Connor Maguire is not happy at all to learn Daphne is his half-sister, as she's also their father's lieutenant in the US while he expects to run everything. Later on Charlie suggests that it's actually her. Connor is motivated to go against Daphne after this, in spite of her maintaining they can work together.

* Misty from ''Anime/{{Pokemon}}'' set out on her training journey in order to prove her worth to her three older sisters.

* English princes (and Later Kings) Richard, Geoffrey and John, as depicted in both ''Theatre/TheLionInWinter'' and most versions of ''RobinHood''

* RobinHood in all of its many versions: the underlying plot driver is the sibling rivalry between King Richard and Prince John and in some versions Will Scarlet is Robin's illegitimate half brother.

** While a "Manning Bowl" never happened, Super Bowl LVII finally gave fans a matchup with brothers playing for opposing teams, namely Philadelphia Eagles center Jason Kelce and Kansas City Chiefs tight end Travis Kelce, leading to their mother famously attending in a custom jacket that was split down the middle between Chiefs and Eagles colors. Travis' Chiefs ultimately defeated Jason's Eagles in a close game. Thanks to the close relationship between the brothers, however, the whole thing ended up being more of a fountain of heartwarming moments than anything remotely volatile (while it was initially reported that Jason said “fuck you, congratulations” to Travis after the game, both brothers have [[https://www.youtube.com/watch?v=wvPv0AlahJs denied]] that any such comment was made -- and even if that actually ''is'' what he said, the body language makes it clear that ''whatever'' he said was said with the utmost affection).

->'''Azula:''' I'm sorry it has to end [[DuelToTheDeath this way]], brother!\\
