* ''{{Buffyverse}}'':
** Spike to Angel, as revenge for all those times Angelus humiliated him and stole his girlfriend. He also butted heads with Riley on frequent occasions.
*** Reaches a new level in ''Angel'', due to the Shanshu prophecy involving a vampire with a soul.
** Angel unwittingly provokes Lindsay's wrath at every turn, from ruining his court cases, to stealing his would-be girlfriend (Darla), to having the entire firm handed to him on a silver platter. ..And then Angel has sex with Lindsey's ''new'' girlfriend, Eve, under the influence of spell and oblivious to Lindsey's connection to her. When Lindsey consoles himself that Eve is one of the only things in his life that Angel "never got his mitts on", Eve wisely holds her tongue. A good thing, too, because otherwise his brain might have imploded.
* Sharon Raydor shows up as this to Brenda in Season 5 of ''Series/TheCloser'', possibly because Commander Taylor is now something of a [[TheLancer Lancer]]. After working together (quite well) to solve a case in the fifth season finale, they agree that they "simply don't like each other." This turns out to be a [[NotSoDifferent big fat lie]]. Raydor went on to take the helm of the Major Case Squad in AfterShow ''MajorCrimes'' following Brenda's departure from the LAPD, and has proceeded to ''[[BotheringByTheBook kick]] [[RulesLawyer ass]]''.
* ''Series/{{Degrassi}}'' and Lakehurst were rival schools, which caused problems when Lakehurst burns down and the students have to move to Degrassi. One main character even [[KilledOffForReal gets stabbed to death]] by a Lakehurst student. Liberty had a rivalry with Damian, who was to be Lakehurst's valedictorian and became her competition for the position when he became a student at Degrassi.
* Crais from ''Series/{{Farscape}}''.
* Carter Baizen to Chuck Bass on ''GossipGirl''.
* ''GreysAnatomy'': Seattle Grace and Mercy West hospitals. Similar to the ''Degrassi'' example, they merged when Mercy West closed down. Some Mercy West characters were killed off, though the others have been accepted as part of Seattle Grace.
* Many of the secondary Heisei in ''Franchise/KamenRider'' play this role at first, then eventually become an ally or a true foe.
* A considerably more benign version of this trope is Prince Arthur and Lancelot from ''Series/{{Merlin}}''. Both of them respect the other, but both are painfully aware of their mutual feelings for Guinevere.
* Eric to Wes in ''Series/PowerRangersTimeForce''. Plus For RivalsTeamUp and Eric becoming TheLancer.
** Deker to Jayden in ''Series/PowerRangersSamurai'' counts as well.
** [[Series/MightyMorphinPowerRangers Jason and Goldar]]...accept no substitutes.
* For each series [[RetroGameMaster Arino]] does multiple games on. Most are simply the Big Bad of multiple games, such as Bowser, but some are enemies he has a lot of trouble with, most notably Red Arimer/Red Areemer/Firebrand and the birds.
* Turk had a rival in Bonnie during the early seasons of ''Series/{{Scrubs}}''.
* Bania in ''Series/{{Seinfeld}}''.
* So Random and Mackenzie Falls are rival television programs on ''SonnyWithAChance''.
* Bimpe from ''{{Tinsel}}'' is Telema Duke's rival, both in the industry and for Soji. Kwame is Soji's rival. Brenda Mensah is Fred Ade-Williams's rival.
* Lex from ''Series/TheTribe'' is a rival to Bray, as well as most other males on the show with any authority. He's also a thug and a petty criminal who thinks he's much more of a MagnificentBastard than he really is.
