ProfessionalWrestling is chock-full of these. To wit:
* [[NamesToRunAwayFromReallyFast The Brothers of Destruction]]: Wrestling/TheUndertaker (Blue) and Wrestling/{{Kane}} (Red).
** In Kane's second most notable tag team, with Wrestling/TheBigShow, Kane played the Blue Oni to Show's Red. Kane tended to be the more stoic (if psychotic) of the two, while Show ranged anywhere between HotBlooded to BigFun.
** Kane's most recent notable tag team, Wrestling/TeamHellNo, saw him again play the Blue Oni to [[Wrestling/BryanDanielson Daniel Bryan's]] Red.
* [[SiblingTeam The Hardy Brothers]]: Wrestling/JeffHardy (impulsive and aerial Red) and Wrestling/MattHardy (more calculated and ground-based Blue).
* Wrestling/{{Edge}} (blue) and Wrestling/{{Christian}} (red)
** Maybe during their initial run, but after going singles, Edge is a much wilder, crazier Red, and since his return, Christian is a calm, relaxed Blue.
* Former WWE Unified Tag Team Champions Mike "Wrestling/TheMiz" Mizanin (angry Red) and Wrestling/JohnMorrison (mellow Blue).
* The Rockers (originally AWA's {{Exp|y}}ies of Wrestling/TheRockNRollExpress from the NWA), Marty Jannetty (Blue) and Wrestling/ShawnMichaels (Red); notable for the fact that the group originally split after they gradually switched roles over the course of their 5-year tag team career.
** In the same vein, the most recent iteration of [[Wrestling/{{DGenerationX}} [=D-Generation=] X]], with Wrestling/ShawnMichaels back in the Red Oni role and partner/best friend Wrestling/TripleH in the Blue Oni role (it can also be noted that [[DoNotCallMePaul Hunter]] can switch the colors pretty much on demand now as a story needs him to).
* Classic big-man tag team [[MeaningfulName The Twin Towers]], where the Wrestling/BigBossman (prior to his HeelFaceTurn) was the Red Oni and Akeem "The African Dream" (after switching gimmicks from Wrestling/TheOneManGang) was the Blue Oni.
* The Outsiders, Wrestling/KevinNash (Blue) and Wrestling/ScottHall (firmly entrenched in Red terrritory).
* Even Wrestling/MickFoley (jokey Red) and Wrestling/AlSnow (serious Blue) meet this trope head-on!
** [[VitriolicBestBuds The Rock and Sock Connection]]: Foley remains the jokey Red while [[Wrestling/DwayneJohnson The Rock]] is the serious blue.
* TNA's Beer Money, Inc. Wrestling/JamesStorm (red) and [[Wrestling/BobbyRoode Robert Roode]] (blue)
* Even the ANNOUNCERS get in on the action!
** The classic team of Wrestling/JimRoss (Blue) and Wrestling/JerryLawler (Red).
** Classic Wrestling/{{ECW}}'s Wrestling/JoeyStyles (Red) and Joel Gertner (Blue). OH MY GOD!!
** Wrestling/MichaelCole (Red) and Wrestling/{{Tazz}} (Blue).
*** When Tazz went to the ECW Brand, Cole became the Blue to Wrestling/JohnBradshawLayfield's hard-Red.
** Wrestling/GorillaMonsoon (Blue) and Wrestling/JesseVentura (Red). Gorilla was firmly Red, however, when teamed with [[Wrestling/BobbyHeenan Bobby "The Brain" Heenan]] (cold, calculating Blue).
*** On that token, [[Wrestling/RoddyPiper "Rowdy" Roddy Piper]] lived up to his moniker when he served as Monsoon's replacement Red with Brain.
* The APA was a good example with [[Wrestling/JohnBradshawLayfield Bradshaw]] as the Ranting Red and [[Wrestling/RonSimmons Farrooq]] as the Blue of a single word. That word, of course, being [[CatchPhrase "DAMN!"]]
* In TNA, you have Mr Anderson (rule-breaking, stubborn asshole Red) and Matt Morgan (higher-minded, honourable Blue), although, in an ironic twist, Anderson's entrance lighting is very blue-themed whereas Morgan's is very red.
* [[Wrestling/{{WWERaw}} Raw]] and [[Wrestling/{{WWESmackdown}} Smackdown]] are this right down to their colors. RAW has more crazy segments and is most of the time aired live while Smackdown is usually geared towards wrestling and is always taped.
* Legendary Wrestling/AllJapanWomensProWrestling tag team the Crush Gals: Chigusa Nagayo (Red) and Wrestling/LionessAsuka (Blue). Neither fell into the absolute territory but Nagayo was usually the more emotional, passionate one while Asuka was the cooler, calmer one. They even ''wore'' red (for Chigusa) and blue (for Asuka).
* Wrestling/MsChif is the Red Oni of [[Wrestling/ChristinaVonEerie MSEERIE]], where her partner is the comparatively quieter and less outlandish of the two and the Blue Oni of [[Wrestling/HunterJohnston Diabolic Khaos]] where she is the comparatively subtle strategist while her partner runs around wild, hitting people with foreign objects while babbling about random topics.
* Delirious is also the red oni of Incoherence, not that Wrestling/{{Hallowicked}} particularly subdued, but he is downright stoic compared to to Delirious.
