History RedOniBlueOni / VideoGames

* ''FinalFantasy'' examples:
** In ''FinalFantasyX'', Tidus and his father Jecht are both HotBlooded red types who favor the IndyPloy and have impulse control issues, while [[TheStoic Auron]] is a blue. [[spoiler:So is Seymour, the main onscreen villain.]]
** ''{{Final Fantasy X-2}}'' has Yuna positioned between red Rikku and blue Paine.
** In ''FinalFantasyVII'', this is inverted with Cid as the Red Oni in blue clothes, and Vincent as the Blue Oni wearing bright red.

* The TechnicalPacifist blue-armored X and the aggressive red-armored Zero in the ''MegaManX'' games.
** And the aloof blue ice-element DarkActionGirl Leviathan and red fire-element berserker Fefnir in the ''MegaManZero'' games.
** And the blue EmotionlessGirl Pandora and berserk (even moreso than Fefnir) Prometheus in the ''MegaManZX'' series.

** Inversion in ''MegaManBattleNetwork''. Lan and [=MegaMan=] are blue, Chaud and Protoman are red. Chaud's the [[AloofBigBrother Aloof]] [[TheRival Rival]] to Lan's IdiotHero, and while Rock is a lot more savvy and collected than his Operator, Protoman's professionalism and businesslike manner still plays Blue Oni to his PowerOfFriendship philosophies.
** Inversion in ''MegaManStarForce'': Geo Stelar, who wears red, is a [[{{Wangst}} Wangsty]] HikikoMori who doesn't actually enjoy fighting, and thus, the Blue Oni. The blue [[EnergyBeing Omega-Xis]], on the other hand, is a hotheaded JerkAss who likes fighting and is very aggresive, and thus, the Red Oni.
** The MegaMan series inverted this from the get go with naive and impulsive KidHero Megaman, who is the one in blue, and his more mature and experienced AloofBigBrother Protoman, who wears red. However, Megaman, who is not a TechnicalPacifist like X but still isn't all that into fighting, ''is'' the Blue Oni in comparison to his BloodKnight EvilCounterpart Bass (who wears black and gold, but still qualifies for obvious reasons).

* ''{{Gauntlet}}'' Savage Warrior [[color:#0000cc:Thor]] and noble Valkyrie [[color:#cc0000:Thyra]] fit their colors, although ''Gauntlet II'' has all heroes change different colors.

* While ''TheWorldEndsWithYou'''s protagonists are very much a mixture of traits (Neku and Joshua being blue with red spots, Shiki and Beat being red with blue spots), a much neater organization can be found among the Reaper Organization. The best example of RedOniBlueOni is probably Koki Kariya (Blue) and Uzuki Yashiro (Red).

* ''{{Disgaea}}'' Has the red haired Demon Etna und the (white-)blue clad Angel Flonne, both with quite different methods and personalities but the common goal to make Demon Prince Laharl a good King.
** In [[{{Disgaea4}} the fourth installment]] we have [[{{Tsundere}} Fuka]] and [[spoiler: her little sister]] [[CuteMonsterGirl Desco]] play this trope straight and inverts it. Fuka has a brash, aggressive personality who takes baseball as SeriousBusiness and Desco has a cutesy, cheery, and kinder type personality. However, their interests conflict with their personalities. Fuka wants world domination and have stereotypical interests in several girly things like sweets and dress-up while Desco desires to be a FinalBoss someday and cause total massive destruction.

** Another inversion is Guy (who wears a crimson gi) and Cody (blue stripes/jeans). Despite his cynical and laid-back persona, Cody is the more cocky and reckless of the two and gets in fights to alleviate his boredom. Guy on the other hand is taciturn, stoic, and reserved and fights to defend his city(game)/uphold the world's balance (manga).

** Come on: ''{{Xenogears}}'' could be almost renamed "Oni meets Christianity (IN SPACE!)": We have Fei, the brash martial Artist, and Elly [[spoiler: technically his substitude mother AND wife since the crash of the Eldridge 10.000 years ago (Freud would have loved this game)]] the more composed officer: Fei's angers are [[SuperpoweredEvilSide a sight to behold]] and Elly is the only one who can calm him [[spoiler: she's probably the only one who's tought enough to wistand the full extant of his anger anyway]], and a flashback shows us that [[spoiler: 500 years ago, during the diabolo's war, and even 40 CENTURIES ago during the Zeboim era]] she was already the blue, calmer part of their couple. Apart Fei and Elly, we have Citan (so blue that sometimes it take time to understand that the man is [[TranquilFury really angry]] ) and the red hot blooded Bart while on the villain side we have Ramsus (who gets reder and reder during the course of the game) and Miang, who is so blue that it even affect her [[ColourCodedForYourConvenience hair]], or the [[PowerTrio trio]] formed by ID, who like Miang is [[ColourCodedForYourConvenience hair coded]], Grahf (middle ground) and [[MagnificentBastard Magnificent Bluestard]] Krelian...

* ''{{Xenogears}}'': Dominia and Kelvena, members of [[QuirkyMinibossSquad the Elements]], are red and blue, respectively. Dominia is impulsive and vengeful, while Kelvena is calm and reserved. [[ColorCodedForYourConvenience They even wear red and blue]].

** Another inversion is Guy (who wears a crimson gi) and Cody (blue stripes/jeans). Despite his cynical and laid-back persona, Cody is the more cocky and reckless of the two and gets in fights to alleviate his boredom. Guy on the other hand is taciturn, stoic, and reserved.

** Sakura Kasugano (blue) and Karin Kanzuki (red) from ''Street Fighter Alpha Three''.

* [[IdiotHero Heart]] [[LoveFreak Aino]] {red} and [[TheStoic Saki]] [[TallDarkAndBishoujo Tsuruya]] {blue} from ''{{Arcana Heart}}''. They even have [[RedHeadedHero red]] and [[ShyBlueHairedGirl blue]] hair, respectively.

** Don't forget [[JerkWithAHeartOfGold Emiele]]'s red to [[GentleGiant Jeorge]]'s blue from Reach. Most clearly seen when rescuing the researcher.

* RadiantHistoria: This actually has two sets of examples. Blue Oni and main character Stocke is very calm and collected in almost any situation, and has a lean body that's usually portrayed as more dexterous than strong. Red Oni Rosche is much more emotional and a little less mature by comparison, though not stupid, and has a very brawny build. For the other pair, Red Oni Raynie is hotblooded, outgoing, and somewhat slow on the uptake. Blue Oni Marco is a little more rational and somewhat sharper and more tactful than his counterpart. (though not so smart that he's ever allowed to overshadow Stocke, Rosche, or any of Stocke's other more intelligent and experienced allies)

* [[{{Legend of Heroes VI}} Legend of Heroes: Trails in the Sky]]: Hotblooded, combative, outgoing, soft-hearted, athletic, sometime tactless (though rarely downright mean or without a good point), mildly ditsy (it comes and goes) GenkiGirl protagonist Estelle is the Red Oni; her cool-headed, book smart, tactful, introverted, mildly sneaky and pragmatic yet not unfriendly or uncaring adopted brother Joshua is the Blue Oni. Their hair colors match this, as well, with Estelle having auburn hair and Joshua's hair being dark.

* ''{{Tekken}}'''s major red/blue example is between Jin Kazama (a stoic and soft-spoken blue) and Hwoarang (fiery with a touch of arrogance, making him red).

** In ''FinalFantasyVII'', this is inverted respectively with Tifa and Cid as the Red Oni in dark clothes, and Aeris and Vincent as the Blue Oni wearing bright red.
*** After [[spoiler: Aeris dies]], Yuffie becomes the Red Oni and Tifa becomes the Blue Oni.

* Inverted in the gameplay of VideoGame/TeamFortress2, where in the Payload and Point-Capture maps the RED team is defending a zone, thus requiring mostly slow and durable classes like the Heavy or Engineer, and the BLU team is attacking, making them more likely to use speedy and swift classes like Scout or Spy. Played straight in the Meet the Team supplemental videos, where [=BLU=]'s calm passivity in the face of [=RED=]'s aggressive bloodlust inevitably results in the [=BLU=]'s [[BloodyHilarious getting drenched]] [[HighPressureBlood in the other team's color]] before they explode into LudicrousGibs.
