* Hamfistedly [[LampshadeHanging lampshaded]] by Rival-san Lendo of the Rival Ninja Corporation in the manga-inspired American comic book ''ComicBook/NinjaHighSchool''.
* The Thing is generally portrayed as this when fighting Hulk.
* The same can be said of Captain Marvel and Superman.
* Namor the ComicBook/SubMariner and the Hulk were both mainly used as [[DesignatedAntagonist obstacles for heroes]] in early comics, which may be why writers decided to pit them against each other. Hulk hates Namor's rudeness and arrogance and Namor hates Hulk's childish behavior and stupidity. The rivalry remained even when they were on the same team. Admittedly thanks to their time on the Defenders they act more like squabbling siblings as opposed to actually trying to kill each other.
* ComicBook/{{Wolverine}} is also seen as Hulk's rival. That's probably because Wolverine debuted in Hulk's book.
* ComicBook/SpiderMan and [[ComicBook/FantasticFour the Human Torch]] have had a friendly rivalry for a long time, pretty much their entire careers, in fact.
* Speaking of Spider-Man, a more dangerous example would be Spidey and [[http://tvtropes.org/pmwiki/pmwiki.php/Comicbook/Venom Venom]]. Even after Venom has "reformed" they're still fierce rivals.
* One of the hallmarks of ''ComicBook/SupermanBatman'' comic book series is that the titular characters are ideological rivals and the reader is treated to their differing opinions of the same event. For example, where Superman sees the discovery of Kara as a love story (finding a long lost family member) Batman believes finding another Kryptonian is a detective story (is she really the noble person she is claiming to be, or is she hiding something?). While both have very different opinions, they generally respect each others beliefs due to their superficially different, but [[MyParentsAreDead surprisingly]] [[DeathByOriginStory similar origins]].
* Ashley Swift is TheRival to Jennifer Mays in ''TheMazeAgency''. Jen's success is all the more galling for Ashley as Jen used to work for her.
* The eponymous ''ComicBook/KatyKeene'' had Gloria and Lucki.
* Chili is this to ''ComicBook/MillieTheModel''.
* Book 3 of ''ComicBook/LesLegendaires'' introduce a group of hero named the [[PowerTrio Fabulous]] (consisting in asian-like swordman [[TheLeader Michi-Gan]], [[LastOfHisKind Comanshawas]] warrior [[TheStoic Shaki]] and Michi-Gan's foster daughter [[ChildProdigy Toopie]]) who started out as this to the [[TheProtagonist Legendaries]]. Notably, while the Fabulous displayed the typical jerkass rival attitude toward the Legendaries at the beginning, it was arguably justified: not only were the Legendaries at this point still [[HeroWithBadPublicity blamed by everyone]] for [[NiceJobBreakingItHero the Jovenia Incident]], but the Fabulous also reproached the Legendaries to have disbanded for two years in reaction to the blame, thus not being there when Alysia needed them ([[ThePaladin Danael]] later admits they were right on this point). On the other hand, the Fabulous placing themselves as replacement to the Legendaries while calling them outdated and constantly criticizing them didn't really made them easy to sympathise with at first. After the two teams were forced to collaborate, they eventually developped mutual respect, and are in good relationship in the following books.
* ''Franchise/{{Batman}}'':
** Jason Todd sees entire Batman Family as his Rivals. Most his plots are primarily based off of his desire to prove he's better. He constantly says that his aim to be a better Batman than Bruce Wayne ever was.
** As Robin, he was rather competitive with his predecessor, Dick Grayson. Though it was more of a one-sided rivarly, since Dick feels/felt friendlier towards Jason.
** Damian Wayne outright declares Tim Drake is his rival for Batman's approval. Tim (while less hammy about it) feels the same way towards Damian.
** Back to Jason, he outright declares to Dick (who is now Batman) that he is the competition.
** The New 52 seems to make it an {{Informed Attribute}} seeing as Jason acts less hostile and competitive to the Family. Though in a flashback (with him as Robin) he does say to Nightwing that life is a competition.
* ''ComicBook/SuskeEnWiske'': Lambik and Jerom sometimes have a rivalry going on.
* ''ComicStrip/{{Nero}}'': Madam Nero and Madam Pheip.
* ''ComicBook/{{Cubitus}}'': Cubitus and Sénéchal.
* ComicBook/DisneyDucksComicUniverse: WesternAnimation/DonaldDuck and Gladstone Gander often try to conquer the interest of Daisy Duck. Donald himself also has rivalry going on with Neighbour Jones. Scrooge [=McDuck's=] financial rival is Flintheart Glimgold.
* ''ComicBook/PietPienterEnBertBibber'': Both Bert Bibber and Theo Flitser try to seduce Susan. Bert feels jealous about Theo all the time.
* ''ComicStrip/DeKiekeboes'': Marcel Kiekeboe and Leon Van Der Neffe often try to get even or the better of each other.
* ''ComicBook/TomPoes'': Bommel and the Marquis de Canteclaer have a rivalry going on. They are both rich noblemen, but the Marquis is so snobbish that he always belittles Bommel whenever he can.
* ''ComicBook/LeonardLeGenie'': Léonard and the Great Albert are rival professors/inventors.
* ComicBook/{{Urbanus}} and Jean-Yves de Cartouche.
