History RedOniBlueOni / ComicBooks

* SpiderGirl (Blue) and her [[spoiler: CloningBlues clone]] April]] (Red) have elements of this, especially once [[spoiler: April]] turns into [[spoiler: DarkActionGirl BloodKnight]] [[MeaningfulName Mayhem]]. Their color schemes are the opposite of their personalities, though.

* SpiderGirl (Blue) and her [[spoiler: CloningBlues clone April]] (Red) have elements of this, especially once [[spoiler: April]] turns into [[spoiler: DarkActionGirl BloodKnight]] [[MeaningfulName Mayhem]]. Their color schemes are the opposite of their personalities, though.

* In {{Asterix}}, Asterix is cunning and relatively laid-back (blue) in contrast to his emotional and sensitive best friend Obelix (red).

* In ''Franchise/{{Tintin}}'', Tintin is calm and smart (blue) in contrast to his hot-tempered friend Captain Haddock (red).

* In ''Franchinse/{{Tintin}}'', Tintin is calm and smart (blue) in contrast to his hot-tempered friend Captain Haddock (red).

* In ''Franchinse/{{Tintin}}, Tintin is calm and smart (blue) in contrast to his hot-tempered friend Captain Haddock (red).

* SonicTheComic Sonic and Shortfuse are the Red onis to Amy's and Tekno's Blue onis also there is The Badnik Army Repair Functionaries (or B.A.R.F.) which has Bert a Red oni and Cam a Blue oni.

** Cyclops is probably the Blue Oni for everyone in the team too, and honestly most people he interacts with in the Marvel Universe as well. Ironically in his relationship with his brother Havok, their signature energy colours are reversed.

** SpiderGirl (Blue) and her [[spoiler: CloningBlues clone April]] (Red) have elements of this, especially once [[spoiler: April]] turns into [[spoiler: DarkActionGirl BloodKnight]] [[MeaningfulName Mayhem]]. Their color schemes are the opposite of their personalities, though.
** May can also be seen as the Red to [[spoiler: Darkdevil's]] Blue thanks to their [[SiblingYinYang CousinYinYang]].

* During the DorkAge when {{Superman}} was an energy being, he was briefly split into two separate characters, the calm and rational Superman-Blue and the hotheaded Superman-Red. This was actually inspired by a classic Silver Age Imaginary Story -- though in that, both Supermen were more or less the same.

* You could make a good argument for {{Batman}} (the cool, calculating Blue Oni) and Robin (the more impulsive Red Oni). Batman is also a Blue Oni to [[ChaoticEvil The Joker]]'s Red Oni.

* In {{Batman}}-{{Superman}} team-ups, usually the writers emphasize Supes' Red Oni qualities and Batman's Blue Oni qualities, even matching their cape colors. Likewise, when they team up, Lex Luthor has his Blue Oni qualities emphasized and the Joker his Red Oni ones, though their color schemes tend towards the purple and green. However, when the Joker makes an appearance with Harley Quinn, he becomes more of a sociopathic Blue to balance her Red.

* [[Characters/{{Batman}} Harvey Dent and Two-Face]] are this in one body, by some interpretations. Harvey Dent is the calm, rational side, while Two-Face is more often than not just portrayed as unrestrained rage and hatred.

* Augustus and Julius Furst, patriarchs of the Furst Family in ''AstroCity''. Augustus is a dignified, spare man, who can calculate anything to the sixth decimal in his head and rejigger any Phlebotinum needed to save the day in minutes while puffing on his pipe. Julius is a shaved-headed BoisterousBruiser who spends his free time knocking back Budweisers and arm-wrestling. When evil-doers show up, Julius chomps down on a cigar, picks up his {{BFG}} and wades into the thick of it alongside his super-powered niece and nephew.

* Danael and Gryf from [[ComicBook/LesLegendaires Les Légendaires]]. Danael is a usually calm and collected [[ThePaladin paladin]] who likes controlling events, tends to plan everything before battle and [[UnresolvedSexualTension had apparently difficulty confessing his feeling to]] [[TheChick Jadina]] [[spoiler:(though, eventually, [[TheyDo he did]])]]. He means the right thing, but will occasionnally be ready to go to extreme measures for the greater good and act like a borderline WellIntentionedExtremist. Gryf, on the other hand, is a BookDumb, [[SlidingScaleOfAntiHeroes Type II]] AntiHero who has no problem doing things like cheating at games, is described as the bravest of the Legendaries, and usually lets his emotions and instinct lead him, but is notably more relaxing than Danael. Both are still best friends, however.

* [[XMen Wolverine]] (Red Oni) and ComicBook/{{Cyclops}} (Blue Oni) - Wolverine's color may be yellow, but he's easily the Red Oni of the team.

* [[Characters/{{Batman}} Harvey Dent and Two-Face]] are this in one body, by some interpretations. Harvey Dent is the calm, rational side, while Two-Face is more often than not just portrayed as unrestrained rage and hatred.

*** Comes up again in ''[[X-Force Uncanny X-Force]]'' with Fantomex, the cool and calculating gunslinger whose powers let him manipulate his enemies into fighting each other. And, as with Cable, Taskmaster, and Domino, they are (sort of) friends.

* [[XMen Wolverine]] (Red Oni) and Cyclops (Blue Oni) - Wolverine's color may be yellow, but he's easily the Red Oni of the team.

** Tomoe and [[CompleteMonster Noriko]].

** In a more literal color contrast, the power of Blue Lantern corps can neutralize the effects of a Red Lantern PowerRing in its user, both the emotional (mindless rage) and the physical ones (severe weakening of the original circulatory system, as the red rings replace this body function).

* While Lady Death was part of ''Chaos Comics'', she was the cold, sinister Blue oni to the feisty, bloodthirsty Red oni of Purgatori!

* from Everywhere in ''{{ElfQuest}}'': there's Cutter and Rayek, Two-Edge and Winnowill, Ember and Suntop, and Bearclaw and Joyleaf.
* During the DorkAge when {{Superman}} was an energy being, he was briefly split into two separate characters, the calm and rational Superman-Blue, and the hotheaded Superman-Red. This was actually inspired by a classic Silver Age Imaginary Story -- though in that both Supermen were more or less the same.

** An "emotional spectrum" has been established in recent years, explaining that each major emotion has a color associated with it: Lantern Corps using the "warmer" colors are unrestrained and selfish Red Oni (red rage, orange greed, and yellow fear) while the "cooler" ones are calm and focused on others as Blue Oni (blue hope, and indigo compassion). The exception are the Star Sapphires who wield violet love; as their color is one of the "cooler" ones but they're easily as passionate as the "warm" Corps.

** Sort of a running theme with Deadpool, actually. Another example of a Blue Oni paired up with him is {{Taskmaster}}, a level-headed mercenary whose unique abilities are based around observation and analysis and who will typically run away from a fight if he determines that he can't win it in contrast with Deadpool's typically cheerful brainless recklesness, but the most striking comparison is probably with [[TykeBomb Domino]], who, like Deadpool, is the cast-off product of a secret government SuperSoldier program, and favours the same style of costume and equipment (even wearing what was essentially a blue-and-black woman's version of Deadpool's distinctive red-and-black bodysuit in the ''Cable & Deadpool'' series), but is typically cold, clinically rational and often emotionally conflicted over her actions, and her special ability is essentially not getting hit ''at all'' in a fight, where Deadpool's powers effectively allow him to [[IncrediblyLamePun wade]] anything that's thrown at him.

** Usagi and [[TheRival Kenichi]]. In both cases this is amplified by their character designs: Tomoe and Usagi are round and "chubby" while Noriko and Kenichi are lean and angular.
* ''TransformersGenerationOne'' villains Runabout and Runamuck [[CreepyTwins (the battlechargers)]] keep eachother in check this way.
* ''[[http://www.indyplanet.com/store/product_info.php?products_id=3429 Gemini Storm]]'' has Elizabeth who is cold and snarky and Midnight who is more prone to outbursts. In battle, though, the moods switch. Midnight calculates every move, whereas Elizabeth is much more... enthusiastic.
* ''SinCity'' has two assassins working for the same organization: Blue Eyes and Mariah. As expected Blue Eyes has [[ExactlyWhatItSaysOnTheTin blue eyes]] and wears blue (she's one of the few characters in Sin City that has color added). Likewise, Mariah is also one of the few characters in the series that isn't DeliberatelyMonochrome. She has bright red hair and wears red spandex. Blue Eyes is the BlackWidow, seducing men and killing them quietly. Mariah is [[DeadpanSnarker verbose]] and perfers just to [[AxCrazy chop people up when she kills them]]. While we never actually see them together, they do reference one another and have the typical "Red vs. Blue" rivalry.
** Dwight, normally a pretty calm guy, has had two red onis to his blue oni. He usually teams up with Miho who is much more violent and probably a little unbalanced. He has employed the help of Marv as well, resulting in a similar relationship.
* The title character of ''{{Shakara}}'' has full red eyes, and is in fact a completely red liquid being in a suit of {{powered armour}}; he is also insane, reckless, and driven exclusively by rage and hatred. This stands in stark contrast to Cinnibar Brenneka, hero of the Shakara, who was always very stoic, rational, and driven by a higher calling. He also had blue yes and body markings.
* Augustus and Julius Furst, patriarchs of the Furst Family in ''AstroCity''. Augustus is a dignified, spare man, who can calculate anything to the sixth decimal in his head, and rejigger any Phlebotinum needed to save the day in minutes while puffing on his pipe. Julius is a shaved-headed BoisterousBruiser who spends his free time knocking back Budweisers and arm-wrestling. When evil-doers show up, Julius chomps down on a cigar, picks up his {{BFG}} and wades into the thick of it alongside his super-powered niece and nephew.

* Raphael and Leonardo of TMNT are Red and Blue oni respectively: Leonardo is calm, thoughtful and self-controlled leader of the team, when Raphael is easily-angered hot-tempered rebel. It's even lampshaded by their bandanas.
* Danael and Gryf from [[ComicBook/LesLegendaires Les Légendaires]]. Danael is a usually calm and collected [[ThePaladin paladin]] who likes controlling events, tends to plan everything before battle and [[UnresolvedSexualTension had apparently difficulty confessing his feeling to]] [[TheChick Jadina]] [[spoiler:(though eventually [[TheyDo he did]])]]. He means the right thing, but will occasionnally be ready to go for extreme measures for the greater good and act like a borderline WellIntentionedExtremist. Gryf, on the other hand, is a BookDumb, [[SlidingScaleOfAntiHeroes Type II]] AntiHero who has no problem doing things like cheating at game, is described as the bravest of the Legendaries and usually let his emotions and instinct lead him, but is notably more relaxing than Danael. Both are still bestfriend however.
