"Hey, wait a second. I know who you are now! You're that guy! The one who kept getting pissed off at me for not remembering... something."Two characters can be competing for the same goal, without one of them even aware of the competition. Maybe the reason they haven't picked up on the rivalry is that it is hard to take their rival seriously. Maybe the rival simply hasn't shown up onscreen at the same time. It might just be that the rival is so much weaker, that they can't be considered a serious threat. Whatever the reason, the rival is competing for the same thing as the other character. Objectives for competition may be the fair maiden's hand, simple revenge, a pot of gold, the title of "World's Best Whatever", or the extra-special MacGuffin of the week. This is common with non-evil antagonists, giving writers a character who can be a source of tension without necessarily being a bad guy. Compare But for Me, It Was Tuesday. See also We Meet Again, which is usually followed by a "Have we met before?", much to the would-be-rival's chagrin. Supertrope to Enmity with an Object in that there's no way an object can be aware that someone has a grudge on it.

Anime & Manga
- One Piece:
- Boa Hancock views Nami and Robin as rivals for Luffy's heart. Not only are they both unaware that Boa hates them for being the sole women on Luffy's crew and are thus that much closer to him, but they also have yet to even meet her in person. Not to mention that Luffy doesn't have romantic feelings for anyone.
- Buggy perceives Shanks as a sort of Sitcom Arch-Nemesis, who he blames for making him eat a devil fruit and losing his ability to swim. Disregarding the huge discrepancy in strength, Shanks is either completely unaware or selectively oblivious to this, thinking that they're still the same Heterosexual Life-Partners/Vitriolic Best Buds they've always been since they were kids. Though in an title image after Marineford, they are showed eating and drinking at a bar together while laughing, so it seems Shank's opinion may be closer to the truth.
- Part-time model Sakiyama Kaori in Airmaster becomes an amateur wrestler, semi-berserker streetfighter solely to challenge Aikawa Maki. Slightly subverted in that she is too loud and crazed to fully ignore, to the point everyone memetically mentions her full name when she appears.
- Ryuuka, the pompous rich leader of the Jihiyou rival house in Hanaukyō Maid Tai. In episodes 7 and 11 of the first series Taro doesn't know who she is, even though he met her in episode 4.
- In Samurai Deeper Kyo, Kyo is approached by a man who had survived an encounter with him in the past. After being stunned by Kyo's swordsmanship, he trains constantly to match Kyo's level by cutting up anyone he comes across. When he meets Kyo in the plot, he proclaims that he has returned for revenge and Kyo responds with, "Who are you?"
- Naga, in Slayers, considers Lina Inverse to be her rival in sorcery, but really just ends up being her sidekick. Naga occasionally surprises Lina with her knowledge of White Magic, is pretty darned good with Black Magic too, and in general is all but stated outright to really be Lina's equal in magic (excepting Lina's knack for the Dragon Slave spell), but she gets no respect from Lina, who treats her as more a one-woman Goldfish Poop Gang than even a sidekick. A big part of this is because Naga, for all her talents, happens to be several orders of magnitude flakier than Lina, which leads to her undercutting her own effectiveness. The fact that Naga introduced herself to Lina by suddenly challenging her out of nowhere, proclaiming they were rivals when they had never even met before is another reason for Lina's lack of interest. The fact that Naga introduced herself by setting fire to the Inn where they were staying and then fell into the fire herself convinced Lina that Naga did not have both oars in the water right from the start.
- Momoko in Chou Kuse ni Narisou considers Nagisa to be her rival, but Nagisa doesn't learn of Momoko's identity until the second half of the series.
- In the Pokémon anime, Ineffectual Sympathetic Villains, Team Rocket often fall victim to this:
- Team Rocket's Meowth sees himself as competing with Giovanni's pet Persian for the boss' attention, although it's clear that the Persian couldn't care less.
- Jessie rivaled May in Pokemon contests during the Hoenn era, but she almost always failed miserably, leading May to sparsely acknowledge her (especially since she was usually in disguise). Subverted in Sinnoh, where Jessie was a more legitimate competition for Dawn, while Kalos zigzags this, since while Jessie was also competent in showcases, Serena still barely noticed her, if more because they rarely interacted, the latter preferring the friendlier competition.
- Pretty much any other antagonist in the anime will be deemed by them as their rival and inferior. Most of them however, prove Eviler Than Thou and nonchalantly smack them out of the picture. Again occasional subversions and zigzags exist (both Team Plasma and Team Flare had this attitude to the trio initially, though it turned out to be Underestimating Badassery when they ended up aiding Ash significantly in their defeat).
- Variation: Haitani and Shirai, Urashima Keitaro's best friends at the beginning of Love Hina, disappear for a while once the plot gets going. Eventually, they reappear just to "see how Keitaro's doing", that is to say, mess up his life more. A Running Gag in the manga has the other characters constantly asking who they are and how they know Keitaro.
- During most of Glass Mask, Maya is unaware that Ayumi sees her as a huge threat to her acting career. And as result, Ayumi sees her as the main rival. Maya, instead, sees Ayumi as an inspiration worth looking up to. It's not until near the end of the Anime series that Maya realizes this when Ayumi, herself, admits it. Once Ayumi confessed that she was thinking about letting Maya fall off a weak wooden bridge and die, but saved her at the last minute, the two end up fighting. Afterwards, they both declare each other rivals.
- Might Guy to Kakashi. Guy is the intense one, and whenever he brings up the "rivalry" Kakashi says something to the effect of "I'm sorry; did you say something?" It's accepted that Kakashi acts like that because he doesn't terribly want to be Guy's rival, and really wishes he would just shut up and go away. That's why, when Kakashi chooses their "competitions", he tends to pick something that will be over quickly and doesn't take any effort, like rock-paper-scissors. Not so much "Unknown Rival" as "Unwanted Rival".
- Humorously, Guy has Kisame as an unknown rival of his own. Guy can vaguely remember him, but never remembers his name until Kisame kills himself.
- Danzou was fiercely envious of the Third Hokage. He had a severe inferiority complex towards Sarutobi, especially during a flashback where he wasn't able to volunteer himself for a suicidal mission sacrificing his life for the rest of his teammates, but Sarutobi did. In his eyes, Danzou wasn't able to live up to his family's and his own beliefs. Not to mention the Second Hokage naming Sarutobi as his successor in front of Danzou, something he had longed for and bitterly desired for the rest of his life. At the same time, he did respect the Third and was even on a First-Name Basis with him. Which is actually kind of a big deal, because he ends up being the first person to use the Third's name - nobody else is shown to be on a first-name basis with him, not even his former squad or his own son.
- Naruto himself was this to Sasuke at the beginning of the manga, as he was constantly trying to outdo Sasuke, but Sasuke didn't really care about him. As he got stronger Sasuke eventually acknowledge him. Unfortunately, to Sasuke, if Naruto could challenge him, it meant his own skills were inadequate, which contributed significantly to his defection.
- Kiba has become this to Naruto (moreso in the anime, but it's there in the manga, too). Does he have a crush on Hinata? Or is it simply being ashamed of Can't Catch Up? Or is it just because the whole "Fox and the Hound" bit is supposed to be funny? Or is it simply because the two are both hot-headed, impulsive and ambitious?
- Sakaki never notices Kagura's self-proclaimed rivalry, even when it is proclaimed to her face, in Azumanga Daioh. Despite that, Kagura doesn't take their rivalry personally and is nice to Sakaki even before they get to know each other. Kagura eventually moves on to establish a genuine rivalry with Tomo, as both have similar levels of energy.
- Gintama has Sougo Okita, the 1st captain of the Shinsengumi, constantly trying to kill his superior, vice-commander Toshiro Hijikata, just so he can take over his vice-commander position. Hijikata, in turn, never seems to take notice of any of this (even regarding Okita's attempts on his life as "unfunny pranks").
- Being a deconstruction of the Fighting Series Played for Laughs, this trope is justified and Deconstructed with protagonist Miki Onimaru of Muteki Kanban Musume who can never remember Kankuro Nishiyama, despite his attempting to serve her with a formal challenge to battle nearly every episode. Justified because Miki is The Bully/School Yard Bully All Grown Up who suffers Attention Deficit... Ooh, Shiny! and But for Me, It Was Tuesday. And deconstructed because as a Fighting Series protagonist, Miki always encounters Bit Part Bad Guys/ Very Punchable Men that defy her, she promptly defeats and immediately forgets; why Kankuro should be different than them?
- In the El-Hazard: The Magnificent World OVA, Makoto is largely unaware of Katsuhiko Jinnai's hatred for him. Whereas Jinnai thinks that Makoto has a secret vendetta against him, given the number of times that Makoto has coincidentally gotten in his way and/or pissed him off.
- In Death Note, Near blatantly ignores Mello's attempts to beat him. Ironically, Not So Harmless Mello ends up actually helping in the end, with his own death.
- Kamina of Tengen Toppa Gurren Lagann seems to have a remarkably poor memory; when the recap episode shows his fight with Viral, he asks Simon if that really happened. This also works for his allies; Kittan is infuriated when Kamina doesn't remember him. Yoko was also this for Nia for a few episodes, taken Up to Eleven when Nia kept on being better than everything than Yoko without even trying. The two of them became friends at the end of the episode after Nia puts her faith in Yoko to rescue her.
- Meanwhile, Viral spends a fair portion of the series unaware that Simon even exists. Due largely to Simon being the Blue Oni to Kamina's Red, Viral only ever interacts with Kamina when they fight. He's even unaware that he'd killed Kamina for some time, and is shocked to learn Kamina hadn't been piloting Gurren Lagann in their fights since.
- Lambo from Katekyo Hitman Reborn! has tried to kill Reborn on a few occasions, but Reborn refuses to even acknowledge his presence, even when Lambo uses a gun to temporarily age himself up.
- Tachikawa Satoka from Gate Keepers 21 spends most of her non-BFS-swinging time talking to/critiquing/lecturing Badass Bookworm Isuzu Ayane only to get ignored, or ditched when her back is turned, much to her chagrin.
- Haruka in Mai-HiME and Mai-Otome (all adaptations) apparently has an ongoing rivalry with Shizuru, which Shizuru never seems to acknowledge. Late in the Mai-Hime anime, Yukino calls out Shizuru on it, saying that Haruka knew she could never hope to surpass Shizuru, but just wanted to be acknowledged.
- Cowboy Bebop inverts this trope with Andy, who is The Rival to Spike for one episode and never remembers Spike, constantly confusing him (and everybody else) with the episode's bounty.
- Kirby: Right Back at Ya!: Dedede apparently considers Kirby his archrival, but Kirby is too naive to return the rivalry. This is in contrast to the games, where Kirby often blames Dedede for evil deeds he didn't do.
- ×××HOLiC has Doumeki, who more often than not is involved in Watanuki's Embarrassing Rescue. Watanuki views him as a rival (mainly due to Watanuki's convinction that Doumeki is vying for Himawari's affection, which is all in his mind) while Doumeki clearly does not take him seriously. Later, the main reason Doumeki seems to show great annoyance at Watanuki's antagonistic view of him seems to be because he wants Watanuki to trust and... like him more.
- A Certain Magical Index:
- Mikoto hounds Touma on a regular basis trying to get him to fight seriously with her, having misinterpreted his mysterious ability to negate her lightning as a sign of some incredible power that he's holding back. His nonchalance toward her and her otherwise remarkable power is a blow to her pride as one of the strongest espers in the city. While no evidence he keeps forgetting her is shown, An instance of this occurs When he receives amnesia, which causes him to forget their meeting.
- Because of Magic Versus Science and The Magic Versus Technology War, various magical organizations or individual mages try various plots to destroy Academy City, which are constantly foiled by Touma and friends. Other than the heroes and a few of Academy City's higher-ups, no one in Academy City is even aware that magic exists or that several science-hating mages want to destroy them.
- Accelerator and Kakine. Kakine, as the #2 Level 5 esper, desperately wants to defeat Accelerator (the #1 Level 5). There's no indication that Accelerator even knew who he was prior to their fight.
- Kuroko wants nothing more than to get Touma out of the way so she can have Mikoto all to herself, while he's unaware that she hates him so much.
- Greta from A Little Snow Fairy Sugar constantly challenged Saga, who was usually distracted by the fairies' antics.
- Takumi of Initial D, for the first season or so, doesn't seem to really care that his enemies—and his friends for that matter—are quite envious of his racing skills; this is not helped by the fact that his first race came after five years of tofu delivery runs. His first race has him not caring about the racing aspect of drifting.
- Hikaru no Go:
- Morishita considers himself Toya Meijin's rival, and strives to create the same rivalry between his students' and Toya's. Morishita's students are somewhat startled by the realization that the Toya school is largely unaware that there's a rivalry going on.
- Also from Hikaru No Go, Kaga's backstory involved his numerous attempts to defeat Akira. Those ended when he realized, to his shock, that Akira had never considered him a rival - their difference in skill was simply too great.
- For that matter, after Sai's first (and even after his second) game against Akira, Hikaru did remember the occasion and the guy, but didn't take him terribly seriously and was completely flummoxed by his 'rival!' attitude, since he hadn't even played those games of go and had no idea how important it was to Akira. Of course, most of the show is then consumed with their burning rivalry that was written in the stars.
- Bakuman。 has a hilarious variation on this: the main protagonist sees genius mangaka Eiji as his rival, but Eiji's not ignoring him because he's conceited. It's because Eiji is such a total fanboy of the protagonist's work that he barely seems capable of understanding why he'd consider him his rival.
- Eiji is conceited, but in a clueless, Genius Ditz kind of way, and he gets into the rivalry on a couple of occasions, since it is visibly true that they're both less commercially and critically successful, and having a harder time finding their voice than he is, and he wants to encourage them.
- As Tsugumi Ohba and Takeshi Obata's project right after Death Note, it's milking the 'rival' thing Obata used to such acclaim in both Death Note and Hikaru No Go, and as an outrageously meta project, it's playing with it.
- In Sgt. Frog, rival assassin Zoruru has some beef with Dororo, but Dororo doesn't remember him.
- Not to mention Tamama towards Angol Mois. In fact, he often wishes death on her in the most gruesome and violent of ways... but she takes little to no notice and is always kind to him. What makes it even sadder is that if Tamama were more reasonable, this could be ended with a simple discussion, because it mainly has to do with Keroro.
- When Al faces off against Barry the Chopper in Fullmetal Alchemist, Barry gets rather annoyed when Al reveals he's never heard of Barry's infamous past.
Yoki: Don't tell me you forgot what happened in Yoswell!!
- Though they recognize each other when they meet up again. There's also Yoki, who starts out as a corrupt official who gets exposed and cashiered from the military because of Ed. When he and the brothers meet up again in Briggs, Yoki is outraged that they don't recognize or remember him.
Al: Brother, did we meet any hobos in Yoswell?
- Touka: while she considers Nodoka to be her great rival, Nodoka doesn't even seem to notice that she exists, which is a testament to her ability to ignore everything except the game itself considering how much Touka grandstands.
- There's also Mihoko for Hisa, who played Hisa in an Inter-Middle tournament during their last year of middle school, and Hisa pressured Mihoko so much she accidentally opened her right eye- which she keeps closed due to it being a different color from her left- in surprise. Hisa then told Mihoko that her right eye was pretty, and Mihoko wanted to see her again to talk with her. Unfortunately, the next day, Hisa dropped out of the tournament due to unknown circumstances, changed her last name from Ueno to Takei, and did not recognize Mihoko when they saw each other again three years later. However, in the individuals match, after Mihoko opens her eye, Hisa finally remembers her.
- In the wake of Nodoka returning to mahjong, her old schoolmates from Nara, the main protagonists of Saki Achiga-hen plan on entering the tournament and challenging Nodoka again, but neither she nor Saki notice at first. Howeve, toward the end of the manga, Koromo tells Saki about Shizuno, and just how dangerous Shizuno's innate talent is to Saki's playstyle.
- There are such characters just in every Gundam series.
- In the original series: Hayato for Amuro. Hayato spends much of the series angsting over how much better a pilot Amuro is and desperately trying to prove that he's just as good (unfortunately for Hayato, Amuro is The Ace and leaves him in the dust from the start). Amuro never realizes any of this is going on, being much more preoccupied with his own issues and rivalry with Char. In a sense this is also the case for Amuro and Char's rivalry, at least at first - Char does recognize the strength of the Gundam and Amuro's growing potential, but doesn't see him as any specific threat; in fact, he meets Amuro face-to-face at one point and helps him out of a ditch. Then Lalah sacrifices herself to protect Char from Amuro when they meet in battle again over Solomon. From then on, It's Personal for both of them.
- Yzak Joule to Athrun Zala, and in a degree to Kira Yamato, in Gundam SEED. In their earlier battle, Yzak just viewed Kira (as the Strike's pilot) as a normal enemy that he must shoot down, but then in one battle Kira badly damaged Yzak's Duel and injured him to the point he got a large scar on his face. As a result, he hated Kira down to his deepest heart, counting his scar as his Mark of Shame that reminds him of Kira (and Strike particularly). After the end of the series, he chose to remove his scar, and marking the conflict between him and the Strike's pilot, Kira.
- In the above's sequel, Gundam SEED Destiny, Shinn and Kira spend the entire series as faceless enemies to each other that only know each other by their Gundams. They do meet briefly, but don't know who each other is. This means that they only know each other by their actions in battle, and Shinn in particular without knowing of Kira's kind shy nature, believes that he's either evil or crazy and either way a very arrogant person that needs to be put down. Kira doesn't think much of Shinn at all, and when Shinn changes machines, doesn't initially even realize it's him he's fighting (while Shinn interesting immediately correctly assumes the guy piloting the brand new Strike Freedom is still Kira). When Shinn meets him again and is told who he is, the idea that this kind man was the guy he was fighting kills any remaining notion that his side was correct.
- Averted with Shinn and Athrun, and in fact pitted against someone that he couldn't write off as a faceless guy who he could believe to be evil (because Shinn knew Athrun was a good person at heart), Shinn couldn't quite muster up his usual performance.
- Gundam 00 has many. In the first season, Patrick Colasour is this to Tieria Erde, while Neil "Lockon Stratos" Dylandy hunts down Ali Al-Saachez for personal issues. In season 2, Mister Bushido fills the role to Setsuna F. Seiei, his season 1 rival. Soma Peries is this to Andrei Smirnov after he killed his father Sergei, while Andrei is this to Saji Crossroad for love's sake.
- Laura from Mnemosyne is considered by Rin to be nothing more than a nuisance.
- Happens twice to Mugen in Samurai Champloo; In the second episode, Mugen is confronted by the man whose arm he cut off in the first episode, who freaks out when Mugen says he doesn't remember him. To be perfectly fair, this appears to have happened just a week or so earlier and it's hard to imagine that week being so jam-packed with excitement that Mugen would lose track of all the guys he maimed. Second is in the three part finale, where the three brothers crippled by Mugen during the raid on the sugar ship converge on him; leader Umanosuke loses his mind even more than Ryujiro did when he hears Mugen has no idea what he's talking about. Again, it's hardly unreasonable to expect him to remember this since the sugar ship raid is one of the major formative experiences of his recent life. But then again, Mugen's a self-centered blockhead.
- Soul Eater: To an extent, Black Star to Kid, who only recently has gained any conceivable chance of posing a problem for one of the actual gods in the series. It takes Black Star's efforts putting his life in danger for Kid to a) fight him seriously and b) claim that he has potential. Before this he was fairly indifferent to the assassin's sense of rivalry.
- In Neon Genesis Evangelion Asuka often comes across as this to Rei, especially where Shinji is involved. Subverted in that Rei's internal monologue indicates that she actually does consider Asuka something of a rival, but since this is Rei she is somewhat confused by these feelings as she cannot fully understand them and she gives no outward acknowledgment of this.
- Ranma ˝:
- Ryōga Hibiki at first glance seems to be this; Ranma basically used to always get the piece of bread that Ryōga wanted at lunch when they were in school together, and then went to China after Ryōga was four days late for the duel that Ryōga had arranged over the bread. In series, though, he's actually The Rival.
- Tatewaki Kunō gets roughly the respect from Ranma that would put him towards this trope, but he's so thoroughly irritating that Ranma is perfectly aware of who he is.
- The closest the series comes to using this trope is the anime-only Villain of the Week the Frog Hermit, who is flabbergasted to discover Ranma had never even noticed that he and his father, while dueling at Jusenkyō, had broken the bamboo pole the Hermit was sitting on and dumped him into the Spring of Drowned Frog.
- Peorth is this towards Belldandy in her introductory arc in Ah! My Goddess. It goes away once the gang gets Peorth to explain exactly why she's so angry at Belldandy.
- Nogizaka Haruka no Himitsu: When Yuuto Ayase met his rival for the second time, Yuuto didn't remember the first time until Shute, his rival, reminded him.
- Lupin III: Lupin and Fujiko are uniquely mutual examples of unexpected rivalry. Although it is usually a Mandatory Twist Ending for Fujiko to betray (anyone, including) Lupin, there are cases where Lupin refuses to give her the prize at the end. More rarely, he may have planned for her to trick him, having a contingency in place, surprising her.
- In Fairy Tail, Evergreen was jealous of Erza for having the nickname "Titania" (townspeople were awed by her strength and called her that, meaning "Queen of the Fairies") and tried to kill her so she could take it. Erza defeats her and says that she never cared about that nickname.
- Inverted and later played straight in Eyeshield 21 where initially Kotaro considered himself to be Musashi's rival... but he only knows Musashi by reputation, and has no idea what he actually looks like or where to find him. Later, though, after Musashi's identity is known, Kotaro ends up becoming the normal kind of unknown rival himself to Musashi. It's revealed at one point that the legend of "Eyeshield 21" wasn't just something Hiruma made up; there's a real Eyeshield 21 who is also star running back on his high school football team. Sena doesn't learn just who it is until the penultimate story arc, though there was a fake-out along the way and he had a few hunches.
- Kenichi: The Mightiest Disciple: When Kenichi is training to fight against YOMI, an old enemy known as Shinnosuke Tsuji (The crazy hair guy that was Kisara's henchman.) appears, claiming he'd been training hard to fight his rival again. Kenichi doesn't remember him, and neither does Kisara.
- Tajima is this to Hanai in Big Windup; Hanai uses his one-sided rivalry with Tajima as motivation to improve, while Tajima competes against himself.
- In Sangatsu no Lion, Nikaidou treats Rei as his greatest rival since childhood. Meanwhile, Rei, while acknowledging his determination in respect, does not show any signs of taking Nikaidou's claims of being his rival all that seriously.
- The so-called Fundoshi Mask from Kyou Kara Ore wa!! is this for Mitsuhashi. Before the series, Mitsuhashi completely ruined his life in self-defence, including giving him the Embarrassing Nickname, but when he shows up again Mitsuhashi can't remember of him until circumstances lead to the poor bastard getting bandaged in a way that resembles having a fundoshi as mask (how he got the nickname in first place). When he shows up again, Fundoshi Mask decides to wear his 'mask' to be recognized immediately... and Mitsuhashi can't remember him in the slightest.
- Natsume in Hidamari Sketch is Sae's self-proclaimed rival, but she's really doing it because she has a Tsundere crush on Sae.
- Occurs in the backstory of Mahou Sensei Negima!. When Asuna arrived as a New Transfer Student at Mahora, Ayaka declared that they were rivals. As Asuna was an Emotionless Girl at arrival, it took her several years to notice. This, of course, means that, given her lack of authority figures, Asuna was basically raised by The Rival, to the extent that what emotions she did develop were developed in response to an annoying Ojou bothering her all the time. Explains a lot, really.
- In the supplementary manga of Magical Girl Lyrical Nanoha A's, no sooner did Fate become a New Transfer Student did she gain a schoolgirl rival in Alisa after the latter overachiever of a student learned that the former was way too advanced for the curriculum.
- In YuYu Hakusho, Kuwabara was this to Yusuke before the story began, as shown in flashbacks. Kuwabara was obsessed with defeating Yusuke, but it took a few fights before Yusuke even started to remember his name. When the series begins, Yusuke still doesn't consider Kuwabara a serious rival, since he easily wins every single fight. Eventually, Kuwabara abandons the rivalry and becomes friends with Yusuke, more focused on getting through the Dark Tournament and then the Black Chapters crisis alive.
- In Space Dandy, the protagonist is pursued by Dr. Gel of the Gogol Empire for reasons unclear. Dandy never seems to really acknowledge them or even seems to realize that he's being pursued by an alien empire.
- Suzuki the Supermarket Clerk wants to one-up High School Ninja Girl, Otonashi-san in their part-time clerk job, but she consistently outdoes him without even being aware of this.
- Oingo and Boingo in the Stardust Crusaders arc of Jojos Bizarre Adventure, who try to kill Jotaro and company, but just end up defeating themselves without the group ever realizing they even exist. The rematch with Hol Horse and Boingo is sort of a step-up, because at least Polnareff realizes that Hol Horse (and only Hol Horse) is trying to kill them. Iggy also attacks Boingo, but only because he accidentally hit Iggy with a crate and not because he found out Boingo's a Stand user.
- Emi and Takeshi from Your Lie in April are both this to Kousei, at least before they reunite in the story. Surpassing Kousei, who always took first place from them as a child, seems to be their only motivation to compete in piano competitions at all — however he never noticed them back then and doesn't recognize them when they reunite.
- Speed-o'-Sound Sonic in One-Punch Man is essentially this to Saitama. Though Saitama gives him some acknowledgement and understands his intentions, he doesn't seem at all interested in him and forgets his name shortly after their first encounter, seeing him more as a pest than a serious opponent.
- Played with in Cardcaptor Sakura. It's not that Sakura doesn't know Syaoran is rivalling her for the Clow Cards, she's even a bit genuinely intimidated by it, just she doesn't understand why it's a rivalry for the large part. She even thanks Syaoran for helping her collect some or even gives him ones she believes he earned more. This complete lack of amnesty eventually wears down Syaoran's competitive streak until he's more just her ally.
- Sixshot of Transformers Energon became incensed with destroying Optimus Prime after believing he killed his brother Shockblast. However while he had near successes, he remained hidden inside a control booth of Cybertron the whole time, usually disobeying and clashing with Galvatron in doing such. This conflict culminated in a coup against Galvatron from which he recovered and killed Sixshot, ironically before Optimus even knew of his existance. This was somewhat poetic, since it was actually Galvatron who killed Shockwave via Unicron.
- In the Nightwing comic, Nightwing has a "nemesis" in the form of Shrike who isn't quite unknown (they both underwent assassin training in their childhood, but Nightwing was undercover and Shrike wasn't) but Shrike is the only one who considers them archenemies. Even during their fight, while Shrike is trying to stab Nightwing to death, Nightwing just ignores him.
- The X-Factor comics circa mid-1990s had a great deal of fun with this one:
- Dick Chalker was a mutant who could turn himself into a manlike dinosaur creature. He used his powers to commit murder, robbery and postal fraud, and inspired hatred of mutantkind in the rest of the Chalker family.
- Dick's cousin Rick Chalker decided to act on this hatred of mutants. In true Mad Scientist fashion, he successfully replaced his hands with enormous, razor-sharp propeller blades. Calling himself the Number One Fan, he was ready to kill every mutant in the world...only to discover that he couldn't open the door out of his lab with them. When he tried to slap himself on the forehead in frustration, he cut the top of his head off.
- The third cousin, Professor Vic Chalker, created a massive robot battlesuit to avenge Rick. In making the first version of the suit, he forgot to take his measurements so he couldn't fit in it. In making the second version, he didn't give it enough of a power supply and it ran out of juice five seconds after he started it, becoming trapped inside in the process. In making the third version, he gave it enough power but forgot to waterproof the suit. He fatally electrocuted himself after he took the suit out in a rainstorm.
- Dick, now calling himself "Carnivore", decided that Rick and Vic's deaths were on his conscience and decided to avenge them by killing every mutant on Earth so none of them could abuse their powers the way he did. Unfortunately, as he stepped out of his house to commence his killing spree, he was immediately killed by a truck.
- All of this led up to an X-Factor annual issue where a mutant-hating former classmate of Strong Guy's showed up, having devoted his life to the dark arts and become a servant of Mephisto. In order to defeat X-Factor, he brought back their three greatest enemies from the dead — the three brothers who had died over the past three issues, none of whom had so much as been seen by X-Factor. So in the massive, climactic battle, an unknown rival resurrected three more unknown rivals. When the villains introduced themselves, Polaris asked if they were sure they had the right X-team.
Strong Guy: That figures! Only we could have a bunch of "greatest enemies" that we never heard of.
- The unnamed villain in the giant-sized fiftieth issue of Fantastic Four was some sort of scientist who had spent decades plotting revenge against Reed. (As in only Reed, he clearly had nothing against the other members of the team.) Why? He didn't say, and seeing as he sacrificed himself to save Reed after Becoming the Mask, fandom likely will never know.
- Supergirl: In the Many Happy Returns arc, Super-villain Rebel craves for killing both Supergirls (Silver Age Kara Zor-El and Post-Crisis Linda Danvers). As long as either of them is concerned, though, he is a pathetic nuisance with delusions of grandeur. When Rebel tries to harass Kara for last time, she shows him how insignificant he is and what the real difference of power between them is. He runs away.
Rebel: So whattaya say we just finish this off with one final dance?
Supergirl: Don't you get it, Rebel? You're not important! You never were! You were just — something to do! Something for Supergirl and me to bounce off of for a while until people and events of real consequence came along!
- Lex Luthor with Superman. Superman is of course aware of how much Luthor hates him but not the level Luthor takes it to. It's been shown that Luthor honestly believes Superman is just as obsessed with Luthor as Luthor is with him, thinking Superman reforming the Justice League was a direct shot on him, and being convinced during 52 that Superman was pretending to be Supernova to strike at him. The truth, of course, is that while Luthor is a threat, Superman doesn't spend every minute of the day worrying about him but trying to help others and even have a normal life.
- Amok, an Icelandic supervillain whose only appearance is in Superman: The 10 cent Adventure. He was stopped by Superman four years earlier. Understandably, this became the defining moment of his life. Just as understandably, Supes saw it as another five minute battle against a bank robber, and never gave it another thought. Amok is quite shocked to realize this.
- Big Ron Gomz insists that he is number one on the JLA Most Wanted list, that he knocked Superman through a building, put the Martian Manhunter in a coma, and that he's the guy who broke Batman's back, but none of the Doom Patrol members he tussles with has ever heard of him.
- Slyde. For a moment he had Spider-Man on the ropes! Read the issue (Spider Man Unlimited v3 #1, for the record), it's very entertaining). And in this case, Spider-Man does know who Slyde is; you don't have a guy as a decently recurring enemy for years without remembering him. He just regards him as little more than an occasional nuisance.
- There's a similar scene in Ultimate Spider-Man, when Shocker manages to capture Spider-Man. Throughout the series, he was played up as a joke, a character who didn't even really qualify as a supervillain that Spidey would easily subdue in the opening pages of an arc to show "business as usual." While he has Spider-Man hanging upside-down he reveals that from his point of view, things weren't nearly so funny, revealing a level of anger and humiliation made only worse by the fact that Spider-Man never gave him a second thought.
- In Eddie Brock's Venom's original backstory, he was just a reporter whose shoddy journalism was exposed by Spider-Man. Eddie Brock claimed to have interviewed the Sin-eater, but it turns out the guy was just a compulsive confessor, and Spidey caught the real criminal. Eddie snapped and held a grudge against Spider-Man that only got worse after bonding with the Venom symbiote. At this time Spidey had never even met Eddie face to face.
- This Trope was combined with What Measure Is a Mook? in the story "Light the Night", a rather dramatic multipart story involving Electro. A subplot of the story dealt with a mugger who Spidey had caught on numerous occasions, but could never remember from one time to the next. The guy hated Spider-Man, not so much because he kept getting punched out and webbed to the wall; he even said he wouldn't mind so much if, for once, Spidey remembered who he was! Eventually, the guy tries to pull a grandiose stunt and rob a high-class party, pretending to be a super-villain (doing a rather lame job of it), and when Spidey shows up, again, he seems enraged by his "arch-enemy's" presence, but Spidey has no-idea who he is. It becomes a moot point a minute later, as Electro tries to pull an even bigger stunt that threatens to wipe out the entire city block. Still, the story ends somewhat happy for the guy; he runs into a beautiful socialite from the party who doesn't recognize him as the criminal, and they hit it off quickly. But when Spidey walks by them on the last page - in his civilian identity as Peter - he still doesn't recognize him. (Maybe he just had a forgettable face...)
- During one story, he is attacked by C-list villain Will O'the Wisp. Spider-Man's response is "And you are...?" Wisp gives a rundown of every encounter they've had, to which Spider-Man repeatedly responds that he doesn't remember any of this. Subverted by Spidey's narration, where he reveals that he knows perfectly well who Will O'the Wisp is, and is just messing with him.
- The Acts of Vengeance storyline was all about this. During the Crisis Crossover which focused primarily on The Avengers but involved most other heroes, members of the super-hero community were subject to attacks by villains they had never fought before or barely even knew- ie. the Mandarin, normally Iron Man's arch-foe, instead battled the X-Men. In fact, most of the villains in question didn't even know the true reason; some had simply been hired out by the masterminds behind the true plot, others had been duped into doing so. (The true scheme was a plot by Loki to destroy the Avengers once and for all by recruiting a council of powerful and influential villains, but they fell apart due to infighting.)
- Kearson DeWitt put Iron Man, or rather Tony Stark, through six kinds of hell during the "Armor Wars II" storyline; he was commissioned by the Marrs twins to take Tony out, but for him it is clearly, indeed emphatically personal. He rants and raves at Stark for some cruel injustice that was done to him - but when the story finally comes to a head, and - after a long and devastating battle - DeWitt's face is revealed to Tony, he does not recognize him. Atypically for the trope, this shocks him profoundly. The idea was that DeWitt was one of the many guys Tony crushed during his selfish rise to power and while DeWitt remembers it clearly, Tony never even knew the guy's name.
- In the later three-annual-crossover "Assault on Armor City", it is revealed (in retcon, natch) that DeWitt is the son of an unrecognized engineering genius, whose designs - DeWitt believes - were stolen by Stark and formed the basis for Iron Man, while the true inventor died 'a broken and penniless man'. It's kind of a bum move which pulls the sting out of the original story.
- An Incredible Hulk Annual has a story of Coyote Cash, an arch-criminal who's foiled repeatedly over the years by various versions of Hulk, beginning with the Hulk accidentally crushing his get-away car while escaping from the Army. After a 3rd release from prison, he tracks down Rick Jones and destroys his house with a bazooka. While he makes a triumphant speech about "being ready for the Hulk", Hulk emerges from the rumble in trademark anger.
Hulk: I hope you're ready now, you stupid two-bit hood!
Cash: I... I give up!
(Cash is meekly dragged away by police as Hulk watches)
Hulk: I wonder who that guy was? It's a funny world, when you can be minding your own business and along comes some stranger to complicate your life.
- Justified in Kick-Ass. Big Daddy doesn't actually have any personal connection to John Genovese; that's just a story he made up for Hit Girl to justify raising her as his sidekick. Big Daddy is actually just a comic nerd who wanted to be a superhero and chose Genovese as his arch-enemy more or less at random.
- Sam & Max: Freelance Police poke fun at this with Mack Salmon, a very angry fish in a bowl who has a bone to pick with the duo for "setting in motion the events which caused his current state." Neither of them knows who he is or what he's going on about (neither does the reader); they decide to just smack him around like any other ineffectual villain they come across.
- In The Batman Adventures, Joe Chill spent the rest of his life in fear of Bruce Wayne taking revenge on him for the deaths of Thomas and Martha. Thing is, in this continuity Bruce never discovered the identity of his parents' killer. When Batman is unmasked while he is trying to save Chill from falling off a balcony railing, the latter panics and falls to his death. Batman is utterly baffled by this since he didn't recognize Chill.
- Iznogoud: Everyone know that Iznogoud wants to be Caliph instead of the Caliph... except the Caliph.
- In Kira Is Justice, O is this, being Mello's counterpart. Justin doesn't even know of him, and the closet thing that O had done so far to challenge him was to send SIS agents to Chicago-partially to bring out L.
- The Immortal Game has an inverted example. The Cadet claims that he and Sir Unimpressive have been archenemies for years even before the war. Unimpressive doesn't remember him at all.
- Earth and Sky: While Apple Bloom knows that Diamond Tiara doesn't like her, it's unlikely she realizes that DT views them as archenemies.
- Baldwin Coster is this to Rhuna at the World Martial Arts Tournament in Dragon Ball X. He doesn't even recognise her, although in his case it's because he's so full of himself that he doesn't bother to remember faces. Add in his sexism and Rhuna's a blank doll to him. In the ensuing fight, Rhuna took extra special pleasure in reminding him who she was.
- Dirty Sympathy Daryan Crescend is one to Apollo for Klavier's affections. While he later finds out that Klavier is cheating on him, he never finds out that Klavier is cheating on him for Apollo and that Apollo sees him as an obstacle and danger to Klavier.
- In Mega Man: Defender of the Human Race, Tron Bonne sees herself as a rival for Mega Man's affections, but both Mega Man and Kalinka don't even know who she is.
- Raven to Celestia in My Brave Pony: Star Fleet Magic III, That is until she kills Twilight Sparkle.
- In the Crisis Crossover fic Shadowchasers Tournament Of Shadows, Ace's biggest goal in competing in the tournament is to duel Ember in the finals and win, because she wants to do so in such a public setting; however, the two have never formally met. (The two are part of the same global organization, and Ember has had a great deal more time in the limelight than Ace, both in-universe and out, managing to defeat and avert two world-threatening crisis on her own. Ace has never achieved such feats, despite having joined at almost the same time. Because the fic is currently in progress, it remains unknown whether or not she'll get her wish.)
Films — Animation
- In Penguins of Madagascar, Dave's disdain for penguins started out when the Penguins stole his glory back at Central Park Zoo back when they were younger. They never really met the guy until this movie and Skipper especially has trouble remembering his name.
- In The Lion King II: Simba's Pride, Kovu never seems to have any idea that Nuka resents him. In fact during the few scenes the two are shown interacting, Kovu never shows anything but love and care towards his brother.
- Kung Fu Panda 2: Lord Shen has spent the greater part of two decades meticulously preparing for his eventual battle with Po, but Po sees Shen as just some random baddie to stop. Po is completely unaware of the deeply personal role Shen played in his history, having only learned he existed a few days before meeting him. Even after he learns the truth, he refuses to make their conflict personal, which absolutely baffles Shen.
- In How to Train Your Dragon, Hiccup is completely oblivious to how jealous Astrid is of him suddenly outperforming her in training. When she confronts him after he officially becomes top of the class, he has no idea how mad she is or why she's getting so physical with him.
Films — Live-Action
- Odd example from The Fifth Element: Korben, the hero, and Zorg, the villain, never actually meet in the entire movie, despite being clearly the good guy and the bad guy. It's not even clear that the two of them realize they're in competition with each other over the stones. The closest they ever get to interacting is either when Zorg orders one million of his employees fired, a pink slip shows up in Korben's mail tube in the next scene, or when Korben and Co. enter one elevator as Zorg steps off the one next to it. The pink slip part is about as impersonal as it gets, as well. An underling tells Zorg that due to possible economic troubles, they want to fire 500,000 employees, possibly in one of the smaller cab companies where no one will notice. Zorg, being a Card-Carrying Villain, orders one million fired instead.
- Street Fighter has a situation similar to the above Superman one. Chun Li pledged her life to bring down M. Bison for having her father shot. But for Bison, it was Tuesday.
- Salieri in Amadeus hates Mozart with a passion. However, he never lets on that he does, and actually is rather nice to the younger man when they are in each other's company.
- This is the case for the first half of The Man with the Golden Gun. James Bond is tracking down Scaramanga on the basis of the bullet carved with his number which was sent to MI6 and interpreted as a threat. The bullet was actually sent by Scaramanga's assistant Andrea, who wanted Bond to kill him, and Scaramanga even admits when he meets Bond that he has nothing against him.
- In Big Fish, Ewan McGregor's character unknowingly grew up with a rival who was constantly overshadowed by him. They end up fighting over the same girl when they become adults.
- In Country Strong, much drama comes from Kelly Canter worrying that Chiles Stanton is going to replace her as the hot new thing. Chiles meanwhile is oblivious to this.
- Sort of happens in Black Swan. While Nina feels threatened by the new dancer Lily, Lily's not really threatened by her.
- Enter the Dragon has the Big Bad confront two minor characters before he ever meets the protagonist of the movie, played by none other than Bruce Lee. Oddly enough, Lee was sent there for the specific purpose of bringing the villain down while the two minor characters were at the tournament for unrelated reasons.
- In Guardians of the Galaxy, Drax wants revenge on Ronan for murdering his family. He's outraged when he can barely get Ronan to pay attention to him. Ronan effortlessly beats him up and boasts that he won't remember Drax after he is dead.
- In A Guide To Recognizing Your Saints Mike merely thinks Antonio is a jerk to everyone. He doesn't know that Antonio is jealous that Dito is blowing him off to hang out with Mike.
- In Repo! The Genetic Opera, Paris Hilton plays Amber Sweet, a spoiled brat heiress with pretensions of being a gifted singer. Amber believes she is due to replace Broadway legend Sarah Brightman's character, Blind Mag, a world-famous opera singer who headlines the Genetic Opera for the all-powerful Gene Co company. Mag must know who Amber is due to her association with Amber's father, but Mag doesn't even acknowledge Amber.
- In the Marvel Cinematic Universe, Ant-Man shows that Hank Pym and Howard Stark had a bitter falling out after the former found out the latter was trying to replicate his shrinking technology to use in military weapons. Hank is so bitter about it that he refuses to contact Howard's son Tony to help him with a mission. Then in Captain America: Civil War, Hank's protege Scott Lang is furious at Tony for locking him, Hawkeye, Scarlet Witch, and the Falcon in prison and tells him that Hank was right about the Starks. On the other hand, this is the first time Tony has ever met Scott and he has no idea who he is or what he's talking about.
- The Hitchhiker's Guide to the Galaxy takes this to an extreme. Mild-mannered and mostly confused Arthur Dent is captured and accosted by Agrajag, who claims that he keeps being reincarnated only to be killed by Arthur Dent every single time, including the times he was a bowl of petunias, a bystander at a cricket match, and one in a time and place Arthur has yet to visit. This, as one may imagine, has left Agrajag rather unhinged, so that when Arthur insists that he's not doing it on purpose and the universe is just "playing silly buggers" with them, Agrajag point-blank refuses to believe it.
- In Robert E. Howard's Conan the Barbarian stories, he and Thoth-amon never actually meet and Conan is never the direct object of Thoth-amon's attacks. In The Phoenix on the Sword Thoth sends a demon to kill the man who enslaved him after he lost his powers who is leading an assassination attempt on then king Conan, actually inadvertently saving him although he also tells the demon to kill everyone with his erstwhile master, thus putting Conan in danger again. In The God in the Bowl Conan just happens to be robbing the museum where a deadly gift from Thoth-amon to a rival is being kept. In The Treasure of Tranicos Thoth-amon is after one of several parties after the title treasure, Conan, once again just happens to inadvertently get in the way. In The Hour of the Dragon Thoth-amon is just mentioned by a group of Stygian priests seeking a way to combat him after his return to power.
- In Warrior Cats, (spoilers for Rise Of Scourge and The Darkest Hour) Scourge desperately wants to kill Tigerstar, who has no idea who he is.
- In Austin Grossman's novel Soon I Will Be Invincible, the relationship between the hero Core Fire and the villain Dr. Impossible is like this.
- A Song of Ice and Fire has a couple of possible examples.
- Cersei very definitely sees Margaery Tyrell as a rival, but it is not clear whether Margaery is actually trying to undermine Cersei or not. It is certainly true that Margaery's family is trying to increase their power at Cersei's expense, but it is unknown if Margaery is knowingly assisting in their schemes, or is genuinely trying to be friendly with Cersei and is upsetting her largely by accident. The latter seems unlikely, since she is shrewd enough to immediately see through Cersei's plan to get her damned in trial by combat, and calls her a "vile, scheming, evil bitch". Cersei's main reason for antagonizing Margery is because of a prophecy that says she will be brought down by a young and beautiful queen. The reader is well aware that that could easily be Daenerys, who Cersei has never even thought of.
- Viserys Targaryen is one for Robert Baratheon: Viserys sees himself as the Big Good to Robert's Big Bad, but Robert (correctly) sees Viserys' sister Daenerys as more dangerous (though for the wrong reasons). Despite this, Robert still considers him a threat, but would likely reconsider this if he knew just how staggeringly incompetent and useless Viserys really is, making this a strange example of Viserys being a Partly-known Rival who deserves to be treated as an Unknown Rival, and probably would be treated as an Unknown Rival if Robert actually knew anything about him.
- In The Fountainhead, Toohey considers himself Howard Roark's arch-rival. When he confronts Roark and asks him, "Why don't you tell me plainly what you think about me?", Roark replies, "I don't think about you."
- The Bible: In the Book of Job, Satan works to undermine Job's faith by ruining his life, intending to prove to God that Job's piety is superficial. Job variously lays blame for his misfortune on bad luck, unkind fate, or his own mistakes, and resists the temptation to blame God, but he never even suspects that Satan might be engineering his misfortune.
- In the Marla Mason series, the chaos witch Nicolette is obsessed with becoming Marla's nemesis, while Marla considers her nothing more than a minor nuisance. In the novel Lady of Misrule, several characters outright tell Marla that her refusal to take Nicolette seriously has motivated her to become a far greater threat than she might otherwise have been, as she is trying to become so dangerous that Marla won't be able to ignore her anymore.
- In the Gotrek & Felix series, the Skaven wizard Thanquol spends decades plotting how to defeat the titular duo after they hunted him for so long and destroyed all his plans. When he finally catches them he finds out that they have no idea who he is, or that the various Skaven attacks they had blundered into over the years were even connected.
- In The Lord of the Rings, Saruman has always envied Gandalf for being the more popular of the two (which was in no small part thanks to him being humbler and wiser). Gandalf on the other hand always respected Saruman and apparently had no idea how much his fellow Maia resented him, being sincere and personable right up to the moment Saruman revealed his true colours and attacked him.
- The Black Tulip: Cornelius van Baerle is completely unaware that he's become Isaac Boxtel's archenemy, and only vaguely remembers him as a next-door neighbor when he finally sees him at the end of the novel..
- Wendy Mass' short story "The Stars at the Finish Line" averts this - the protagonist's academic rivalry with a girl he has a crush on has nabbed him excellent grades. When he mentions this to her close to the end of the story, she acts confused...then laughs and reveals that of course the rivalry was mutual; she was just messing with his head.
- In The Dinosaur Lords, Falk considers Jaume to be his rival and contantly attempts to one-up him, undermine him and, above all, prove that he's worse than Falk. Jaume, on the other hand, has no idea of this and considers Falk to be little more than his co-worker, though one who ascended through ranks admirably fast.
- Alexis Carew: In the backstory, Rashaed Coalson for Dunholm Carew, which leads to a one-sided family feud. When it was Dunholm's turn to pick first on land claims during the colonization of Dalthus, several times he happened to pick out claims that Rashaed wanted. Dunholm insists to the Coalsons to this day it was pure coincidence, but Rashaed became convinced Dunholm was deliberately screwing him and taught the hatred to his sons and grandsons. Later Rashaed sabotaged the colony's antigrav hauler when it was headed to the Carew estate to bring Dunholm's wife to Port Arthur for treatment, leading to her Death by Childbirth. Later his son Daviel made a high-speed pass over Alexis's parents' buggy, spooking the horses to a crash that killed both of them.
- Although Angel knows precisely who Lindsey is, he doesn't take him very seriously as a threat during the show's final season, while Lindsey sees himself as Angel's archrival. They eventually team up against a bigger threat, and in the end, when Lorne shoots Lindsey on Angel's orders, the only thing Lindsey's angry about is that he apparently wasn't important enough for Angel to kill personally, which was simultaneously a little sad and deeply, hilariously pathetic.
- Subverted with Sahjhan in season 3 who wants revenge against Angel, who has no idea who he is. In season 5 it's revealed Sahjhan really just wanted to keep Connor from killing him in the future, which he does.
- Played for Laughs in "Harm's Way." Someone has set Harmony up for murder, and eventually it turns out to be...some other vampire chick who works at Wolfram and Hart. Apparently, she's ticked that Harmony got the job she wanted just because Harmony already knew the boss.
- Buffy the Vampire Slayer:
- The Trio start out this way. They gradually are noticed more and more, culminating in Warren's accidental killing of Tara. That got the Scoobies' attention. Specifically, Willow's. Is Warren taken seriously as a villain? Yep. Is he alive? Not so much.
- And then there was Harmony who no-one took seriously at first. She eventually got the gang's attention... well for a moment, but once Buffy saved Dawn, Buffy completely forgot about her. Harmony continued to think Buffy was after her though, even asking Spike to harbor her. Harmony even hid in a coffin when Buffy came to Spike's crypt once thinking that Buffy had found her and was going to kill her. Buffy was actually there to question Spike as usual and had no idea Harmony was even still around.
- In Power Rangers Wild Force, Jindrax sees himself as having a grand rivalry with Taylor. Taylor... doesn't. After their Enemy Mine moment before Jindrax and his partner Toxica ride off into the sunset, Jindrax expresses regret that their "famous rivalry" is over, and Taylor graciously says "Well, you were a... worthy opponent, I guess."
- Merlin (2008):
- An interesting example is Nimueh. Though she is a formidable opponent, most of her evil plans are done from a distance, and Prince Arthur never discovers who she truly is after she pulls a Decoy Damsel on him. She interacts only once with King Uther (who would be her major foe) but then dies in the season finale without any sort of confrontation with either Uther or Arthur. In fact, it's unclear whether they even know that she's dead.
- It happens again with Morgana. As of the end of series 4, Arthur has no idea that Morgana killed Uther, resurrected Lancelot, enchanted Guinevere to cheat on Arthur, or brainwashed Merlin into trying to kill Arthur.
- A Love Triangle variation occurs when Princess Mithian arrives at Camelot in the hopes of marrying Arthur. At this stage Guinevere is in exile, and although Mithian eventually tumbles to the idea that Arthur isn't interested because of another woman (asking "who is it that trumps a princess?" and "what great family does she come from?"), Guinevere never learns of Mithian's existence at all. Mithian does return in season 5, but it's unclear in Gwen knows that Mithian was Arthur's former fiancee or if she just thinks of Mithian as a political ally that Arthur feels duty-bound to help.
- Mad TV took quite a few shots at Saturday Night Live, but the only time SNL ever even referenced MADtv was a Weekend Update bit where Seth Meyers made a joke referencing his brother Josh being a cast member on that show.
- Dr. Rich gained one in Jeff due to his Nice Guy persona and gifted ability at pottery.
- Jeff and the Black Rider during season two's Paintball Episode(s).
- This extends to Real Life where Community views itself and Glee as Dueling Shows. They make fun of them and its fans constantly bash Glee. Glee has never mentioned Community once and its fans seem unaware of the rivalry entirely.
- On The Colbert Report the following exchange takes place:
Colbert: Ted Nugent has condemned your generation as lazy and apathetic. Your response?
NYU Student: Who's Ted Nugent?
- Mad Men:
- Ted Chaough (pronounced like "Shaw") declares himself the rival to Don Draper. Draper had never even heard of the man when they first meet, although Chaough's challenge leads Draper to do some things to prove who's the better adman.
- When Ken Cosgrove gets a short story of his published in a national magazine, Pete Campbell jealously attempts to get a story of his own published, even coercing his wife into meeting with an ex-boyfriend of hers who's a publisher. When Ken and Pete are named joint heads of accounts, Pete resents having to share the position, while Ken seems perfectly happy to share. Then when Sterling and Draper approach Pete about starting a new agency, Pete asks if they approached Ken with the opportunity first.
- Not quite unknown, but in The Big Bang Theory, Sheldon spends a good deal of mental energy seething against his "arch-rival" Wil Wheaton. Wheaton, for his part, just laughs off Sheldon's challenges and easily defeats him whenever they come into contact. Lampshaded when Sheldon finds a new target for his wrath.
Sheldon: You've already signed something for me, Brent Spiner. Your name on my list. From this moment on you are my mortal enemy!
Wil Wheaton: Don't worry, it doesn't take up a whole lotta your time.
- In his first appearance on The Suite Life on Deck, Bailey's ex-boyfriend Moose is entirely unaware that Cody a) has feelings for her and b) sees him as a romantic rival. Throughout the episode he is kind to Cody, doing things such as thanking him for trying to make Bailey feel less homesick and being reluctant to arm wrestle him for fear of injuring him. Cody, on the other hand, continually tries to show him up to impress Bailey, only to fail at every event, which Moose sees as fun competition.
- Back in 2006, the rivalry between 30 Rock and Studio 60 on the Sunset Strip had an element of this, with 30 Rock being the unknown one. Funny how that worked out. See this advertisement, for example.
- On Suits Harvey Specter is a star lawyer in one of the top law firms in New York City. He represents scores of famous athletes helps close billion dollar deals. During one case he runs into Travis who proclaims himself Harvey's rival and vows to crush Harvey. Harvey never heard of the guy before and is hardly intimidated by this 'rivalry'. Sure enough, whenever Harvey and Trevor face off against each other in a legal case, Harvey wins.
- Played with in V.I.P. when a noted Russian-trained assassin is after one of the firm's targets. Tasha, the former KBG agent, talks of how she's fought with this woman several times and they have an intense rivalry going. The killer is defeated thanks to Val (who's only posing as a bodyguard when she's really a goofy Valley Girl) and Tasha informs the killer she's beaten. To her shock, the killer says she's never met Tasha before but "you have beaten me once more, Valerie Irons." Apparently, the woman's pride and ego leads her to believe a "world-class bodyguard" like Valerie must be someone she tangled with before. She's led away as Tasha vainly tries to explain that she's the woman's rival, not Val.
- In Psych, Detective Carlton Lassiter has been chasing an art thief named Pierre Despereaux for much of his career, always trying to outsmart the criminal he considers his greatest rival. When Despereaux is finally arrested (thanks to Shawn), Carlton gloats at Pierre that he is the victor. Pierre looks at him in confusion and tells him that he has no idea who he is.
- The Disney series Pair of Kings has Lanny constantly attempting to kill or at least banish his cousins, Brady and Boz (and later Boomer) so he can become king of their island nation. Not only are his cousins oblivious to his scheming, they treat Lanny as a goofy friend, which just infuriates him more.
- In an episode of Star Trek: Deep Space Nine, local doctor Julian Bashir discovers that the valedictorian of his class is coming to the station. While he doesn't exactly consider her a 'rival', he is rather shocked to find she doesn't even recognize him. This is eventually subverted when she reveals that whoever pointed out the salutatorian to her accidentally pointed to a random Andorian Julian had been talking to at the time; in other words, she did respect Bashir but just didn't realize he was human!
- Blackadder: In the first season, Prince Harry is too thickheaded to see Prince Edmund's (who is also very thickheaded) very obvious attempts to one-up him and become the heir of the throne. Heck once Edmund became the Archbishop as part of the also obvious political machinations of their father, Harry being mindblowingly religious starts treating Edmund as if he was the Chosen One and asking him for spiritual guidance.
- Played with in the fourth season as Baron von Richtofen believes himself the Worthy Opponent to Flasheart, talking of their epic rivalry and assuming they'll have a conversation of mutual respect before a duel of honor. Sadly for the Baron, Flasheart just sees him as another German to shoot.
- In the sixth season of Rizzoli & Isles Jane finds herself being stalked by someone who sets fire to her apartment, sends threatening messages and arranges for Maura's abduction. It turns out to be Alice Sands, a former classmate of Jane's from the police academy who had long been used to coming in first thanks to her demanding father but ended up always behind Jane in training. When Jane graduated top of the class, the woman's father basically disowned her and her life went downhill, all of which she's blamed on Jane, who's amazed as she never even knew the woman in the academy and didn't know they were "competing."
- When Alice is arrested, she launches into a major speech on how she was always in Jane's shadow and grew to hate the woman. Jane flatly tells her "You know what I remember about you from the academy? Nothing." Despite that, Alice still seems to consider her and Jane as major enemies.
- Jonathan Coulton has the song Nemeses which is eventually driven by this trope. Once the protagonist catches on, he begins to exploit the trope... though the song's tone suggests heartbreak, rather than triumph.
Ah yes, my old friend
You are a master of this game
The hidden blade when you pretend
That you don't even know my name
Sometimes it's hard to tell
If you even notice me
Maybe it's just as well
It's better you don't see
The way I'm running just to keep your back in view
In your shadow, waiting for the perfect moment
- During the beginning of Lil Bow Wow's rap career, he made a few songs, calling out Will Smith for not making hardcore gangsta rap songs during his career. Will Smith, who's now more into acting than rapping, was unaware of Lil Bow Wow's jabs, until someone finally asked him about it in an interview. He ended the possible rivalry simply saying "I don't respond to children."
- Dave Pirner of Soul Asylum started a feud with Primus because he thought their song "Wynona's Big Brown Beaver" was mocking his girlfriend Winona Ryder, and at a Soul Asylum concert renamed a song to "Les Claypool's a Big Fucking Asshole". Meanwhile, Primus mastermind Les Claypool pointed out that the song wasn't about her, and Ryder said she didn't mind anyways.
- Henry Rollins cheerfully describes this with a dash of Always Someone Better between himself and Iggy Pop. The bit is well worth watching.
- Perhaps the most well-known wrestling example: Starting in the mid-nineties, Shane Douglas has spent over a decade running down Ric Flair. Flair barely paid him any attention. This didn't stop even after Douglas finally got a program with Flair in WCW in 2000 (and beat Flair twice).
- During the last year of WCW, Booker T was clearly being modeled as a copy of The Rock with promos, popularity and a finisher ("The Bookend") that was a copy of the Rock Bottom. When Booker joined WWF in 2001, he interrupted the Rock in the ring to run the Rock down and say he was the better man. The Rock's reply: "Who...in the blue hell...are you?"
- TNA, as part of its campaign to compete with WWE, markets itself as a Darker and Edgier alternative to WWE, being more violent and bloodier, even going so far as to make occasional not-so-veiled quips at their "competition". WWE responds by...going about their business as usual, not paying any mind to them.
- Then there was that ridiculous and pointless storyline where BG James and Kip James as the "Voodoo Kin Mafia" would spend weeks mocking Shawn Michaels, Triple H, and Vince McMahon. They would often challenge the three to a fight with $1 million on the line, wait a few minutes, then denounce them as cowards for not showing up. The three never gave any indication they were aware of this...Michaels did make a reference to someone "jerking a curtain" but even the fans mistook it as a jab at Kurt Angle rather than the James gang.
- According to some backstage reports, this wasn't simply a "dig at the WWE" angle- this was a genuine attempt by TNA to do a crossover with WWE, the $1 million prize money was apparently real (while many of their top draws worked second jobs to pay the bills). They actually sent a message to WWE front office, asking if the head of the largest wrestling promotion in America and two of his biggest stars would appear on their show broadcast from Universal Studios. Apparently Dixie Carter was legitimately shocked when they ignored her, and kept checking at the TNA office to see if Vince had left her any messages.
- John Cena's first major feud was as the Unknown Rival to Brock Lesnar. Lesnar injured Cena in a match, leading up to months of Cena putting out videos trash talking Lesnar while he recovered. When he returned, Cena would even adopt a new Finishing Move, the F-U, as a mockery of Lesnar's finisher, the F-5. Lesnar showed absolutely no response to Cena, and when they met again... well, Lesnar beat him again, though Cena actually looked really good in the match, even in defeat, solidifying his status as a rising star.
- In 2004 H2Wrestling acted as such to Ring of Honor, running directly against it with fired ROH wrestler Teddy Hart. ROH was in a moment of weakness, having lost its distributor to the RF Video Scandal, but for the same reason didn't pay H2 or Hart any mind and Hart making a brief return to ROH in 2009 after it went under.
- The Miz was this to John Cena during their first feud in 2009. Averted since then, however.
- He got this again in 2011, where The Miz was WWE Champion and was supposed to be the main event at Wrestlemania against Cena. Unfortunately for Miz, Cena and the audience were far more concerned with Cena's problems with The Rock. It wasn't until Miz ambushed and practically murdered Cena that anybody really remembered that he was actually in the equation at all.
- TNA had it's own unknown rival in the form of Pro Wrestling Syndicate, who it actually did acknowledge...after eight years, during a conflict with its much more known rival Global Force Wrestling. Though the Syndicate was very Tongue In Cheek on their own end, nowhere near as persistent or antagonistic as TNA was towards WWE.
- Within Ring of Honor itself, the Briscoes Decade feud was setup by BJ Witmer encouraging Adam Page to call out Jay Briscoe while Briscoe was not around in an attempt to make Jay look bad. Page, not really getting the point, went on to confront and challenge Jay on the first show they were both on together after this. Jay accepted, but not before admitting he had no idea who Page was.
- The England vs. Germany football rivalry continues to rage harder and harder into the 2010s... or at least it does in England. The Germans could not care less about England and are much more concerned with their actual arch-rivals, the Dutch.
- One thing about the 1966 match that did rankle with German fans for a long time was England's controversial third goal; as a result of that, when in a 2006 World Cup match a bad refereeing call deprived England of a valid goal, there was much celebration of a 40-year-old injustice being righted.
- The city of Baltimore lost their longtime football team, the Colts, to the city of Indianapolis in the spring of 1984. The fans of the team have since sported a longtime hatred of the team for abandoning them, as well as the owners of the team (Robert Irsay at first, then his son Jim after Robert passed away). Since Baltimore gained a new NFL team (the Ravens), whenever the Colts have visited, they have been introduced as the "Indianapolis professional football team" (pointedly avoiding the nickname "Colts"), among other indignities. Those in Indianapolis have no particular hatred of the Baltimore Ravens (or the city of Baltimore in general); many Colts fans don't even know there is a rivalry, and the rest simply don't care.
- Meanwhile, the Cleveland Browns claim rivalries with all three teams in their division: With the Pittsburgh Steelers as a traditional rivalry; with the Cincinnati Bengals as an intrastate rival; and the Ravens for taking the original Browns from them. Unfortunately, due to their...ineptness...at fielding a competitive team, those three teams focus more on each other than the Browns.
- Both fans and players of the Cincinnati Reds and Milwaukee Brewers have a bitter hatred of the St. Louis Cardinals due to the later team's constant success within their division (and for Brewers losing to the Cardinals in their only World Series appearance), but most Cardinal fans did not realize this, as they were more focused on the Arch-Enemy Chicago Cubs and the Friendly Rival Houston Astros. That was until players on the Reds (Brandon Phillips in 2010) and Brewers (Nyjer Morgan and Zack Greinke in 2011) started insulting the Cardinals. The fans became very aware of the rivalry after that.
- Fans of the San Diego Padres absolutely hate the Dodgers, bitter at how Dodgers fans have a habit of traveling en masse to San Diego for games and often nullifying their home-field advantage, as well as how the Dodgers are simply their closest geographical rivals in general. Unfortunately for them, their hatred can never be reciprocated, as the Dodgers tend to save all their hate for the Giants, their ancient enemy.
- In the NHL the Nashville Predators and the Columbus Blue Jackets both see the Detroit Red Wings as a major rival. The Red Wings on the other hand are focused on the other Original 6 teams (particularly division rivals - Chicago when they were in the Central; Toronto and Boston now in the Atlantic), and the Pittsburgh Penguins.
- The Preds were just getting recognized by the Red Wings as genuine rivals (after Nashville won their third playoff matchup in 2012, but the Wings have since moved to the Eastern Conference. Nashville has to focus on Chicago now... but the Blackhawks have been in a heated rivalry with the Vancouver Canucks.
- Blue Jackets fans, being in the heart of Ohio State territory, hate the Red Wings and everything else from "that state up north". How a Wings fan sees the Jackets? "Oh, you guys have a team? How cute." It doesn't help that Detroit swept Columbus the one time the Blue Jackets made the playoffs before the 2013 realignment.
- NCAA Division 2 Lone Star Conference. Midwestern State University and Tarleton State University are hated rivals. Like, Red Sox-Yankees hated rivals. Both of them completely ignore West Texas A&M, who simply believe that both schools are their biggest rivals, and focus on each other. This even got taken to new heights in the 2012 LSC Championship semifinals (basketball), where TSU played WTAMU. WTAMU's fans even tried to invade Tarleton's side of the court. What did Tarleton do? Absolutely nothing. Not even attempt to drown them out.
- 2012's football season may have changed that. West Texas's student body "declared war" on MSU's student body in the build-up to the football game on the weekend of November 3, due to this game's winner likely winning the conference and the loser likely going to the dreaded Kanza Bowl (highest-ranked non-playoff teams go, but it's on a bad date and the weather is usually terrible). In the six teams played between the two schools' various sports teams that week, the home field advantage has been minimal, and the games have been rather violent where applicable.
- See Miracle Rally under Real Life.
- In NCAA Football the Marshall University Thundering Herd plays this to the West Virginia University Mountaineers. Marshall fans consider this an important heated rivalry and the "Friends of Coal" bowl to be a must watch event. WVU fans consider their annual meeting a pointless game against a mediocre, obscure team.
- The North Carolina State University Wolfpack considers the University of North Carolina Tar Heels to be their rivals. The NC State side of the rivalry is quite heated and intense. UNC, however is too busy with one of the greatest rivalries in the history of college basketball to pay much attention to State, and considers NC State to be, at most, an annoying little brother.
- Part of this is because the NC State-UNC rivalry used to be bigger than the UNC-Duke Rivalry, but as Duke has risen and NC State has fallen, it has faded in UNC's eyes. This just makes NC State fans madder.
- In English Football, there was a survey as to who clubs consider their chief rivals. Less than half of the "rivalries" were two-way. For example, Manchester United and Liverpool have one of the most intense rivalries in sport. But don't tell that to Arsenal, Bolton, or Leeds, which consider Man Utd their archrival, or Everton, which considers Liverpool its arch-rival.
- The Montreal Alouettes, whose traditional rival (Ottawa) was out of commission after folding twice, had a few of these until a third Ottawa team started up in 2014. Their Labour Day Classic game (traditionally a time where the whole league pairs up in rivalry matches) shifted to an East-versus-West game against the BC Lions, a team that has no real rival, but they never treated BC as their new rival. In 2009, an attempt was made to found a team in Quebec City and have them be Montreal's rival because they'd be in the same province, similar to Edmonton-Calgary and Hamilton-Toronto. Montreal basically laughed it off and shut down their attempt, saying any bid to make another team in their province would have to go through them. Now that Ottawa has a team again, however, the fact that it's technically a new franchise hasn't stopped Montreal from igniting the old flames, probably because they're not the original Montreal Alouettes either and actually began as the Baltimore Stallions during the American expansion experiment.
- In NCAA Division I ice hockey, Rensselaer Polytechnic Institute has decided that Clarkson University is their main rival, while Clarkson focuses primarily on its rivalries with St. Lawrence University, it's main mutual rival, and Cornell University. Ironically, Clarkson is somewhat an unknown rival to Cornell, which believes its true rival to be Harvard, another Ivy League School, although, unlike RPI students, Clarkson students generally realize that Cornell does not consider them a rival.
- Michigan State University considers the University of Michigan to be their biggest rival. Unfortunately for them, while Michigan does consider it to be a significant rivalry, it plays second fiddle to Michigan's intense rivalry with Ohio State, stemming from the state border dispute over the ownership of the Toledo Strip. In fact, Michigan fans will root for MSU if they are playing Ohio State because they hate them that much.
- Rex Ryan, head coach of the Buffalo Bills and formerly of the New York Jets, seems to consider Bill Belichick of the New England Patriots to be his Arch-Enemy, constantly calling him out and talking smack. Belichick, on the other hand, hardly seems to even notice Ryan, though being Belichick, it's as much the way he is with everyone, not truly lack of interest (his preparation for all opposing teams is exhaustively intense and informative) - Ryan is nothing more than the next entry on the schedule to him.
- In regards to South-American national soccer teams, the "Rivalry of the Pacific Ocean" often comes off as Peru having this towards Chile. The otherwise more or less friendly Peruvians tend to rage at Chileans whenever it's time for their national teams to play in Peruvian soil, which often takes Chileans by surprise since they tend to focus far more on their next-door neighbors: Argentina.
- In what is probably the most extreme example, UConn head football coach Bob Diaco decided to create a conference rivalry game for the team after losing their traditional rival games during the 2013 conference realignment. He chose the University of Central Florida and went on to create the "Civil Con F Li CT" and have a trophy made up. However, UCF has no interest in the rivalry whatsoever, going so far as to leave the trophy at UConn's stadium when they first won the game in 2016.
- Although Count Paris is technically Romeo's rival for Juliet, he's never made aware of that fact. He dies without ever realizing that the girl he wants to marry loves someone else. Romeo is vaguely aware of Paris's interest in Juliet, but he doesn't learn of it until after Juliet's seeming death; when he does, his reaction is more a feeling of kinship with Paris over their shared loss than rivalry.
- N in Pokémon Black and White is this to the player character until he beats the champion and challenges you with one of the legendary dragons.
- In Pokémon Crystal (and Heart Gold and Soul Silver, where the storyline is nearly identical) the player meets a mysterious trainer named Eusine who is obsessed with finding the mythic Pokémon Suicune. Because Suicune seems to show up wherever the player shows up, Eusine starts to see the player as a rival in his goal, and at one point even challenges the player to a Pokémon battle to win Suicune's respect (even though Suicune clearly could care less).
- Nippon Ichi just seems to love this trope. As befitting of their storyline status, these characters tend to fill the Goldfish Poop Gang mold to a tee. Examples include:
- Vyers from Disgaea, who was unflatteringly re-named "Mid-Boss" by Laharl during their first encounter and never referred to by his real name again. Ironically, he happens to be the main character's dead father having temporarily returned to test his son's strength and character. Bet getting called "Mid-Boss" wasn't part of his plan.
- Axel from Disgaea 2: Cursed Memories. Axel becomes this again in Disgaea 4, but with a twist; he hates Valvatorez with a passion, after Val's rebellion made Axel look like a rebel too, and he lost his job and status. The twist is that Valvatorez actually thought Axel was an ally, thanks to Fenrich's lies, and is utterly incapable of understanding that Axel has anything against him, even claiming he's an imposter because the real Axel wouldn't do that.
- Disgaea 3: Absence of Justice has the Vato Bros, a trio of recolored Orcs that challenge Mao every few stages. Mao sees them as useless weaklings, and even dubs them 'Trio De Losers' due to their Spanish accents.
- Alexander (referred to as "asshat", or simply "Alex", by Zetta) from Makai Kingdom.
- Another Nippon Ichi example: Odie in Soul Nomad & the World Eaters basically invokes this trope within half a minute of his first appearance. He shows up and immediately boasts to the hero about how awesome he is, gets angry when she ignores him, and then tries to kill her when he finds out that she honestly doesn't know who he is, calling upon an old farmer and his two dogs. Yep, you guessed it, they're the Goldfish Poop Gang.
- Don Paulo has sworn revenge on Professor Layton. Layton has no clue why until the third game (Back when they were both in college, Layton had entered a relationship with Paolo's crush, who was completely unaware that Paolo was even interested in her).
- Fire Emblem:
- The Tellius duology has a knight called Kieran, who is the sworn rival of Oscar. Kieran constantly trains so that he can someday outdo Oscar; Oscar largely ignores this and only ever mentions their alleged "rivalry" in order to manipulate Kieran into accepting a gift that he refused to take. Keep in mind KIERAN SECOND COMMANDER OF THE CRIMEAN ROYAL KNIGHTS! is a guy who shouts his name and rank at his opponents in battle, and wants to keep an axe given to him by his mentor on a mantel. Really, his ending for the 10th game sums him up perfectly "Kieran served the royal family with nearly fanatical verve. His voice could be heard from anywhere in the castle."
- Sylvia and Fury are an amusing example in Geneology of the Holy War:
Sylvia: Hey Fury, you don't by any chance have a thing for Levin, do ya??
Fury: What? I don't. He's just... Prince Levin is an extremely important person to Silesia.
Sylvia: I seeee. So you don't mind if him and I go out??
Fury: No, I don't mind... (?)
Sylvia: Really?? You're not pretendin' t'not like him or somethin' are ya?
Fury: Pretend? What ar—... why would I need to pretend??
Sylvia: I don't know. Well, then I'm goin' after him.
Fury: Umm... whomever is to be the next queen of Silesia needs to have a little grace and dignity like our own Queen Lahna.
Sylvia: So you're sayin' I'm no good somehow!? How rude!
Fury: No, I'm just...
Sylvia: Hmph, Fine! You just wait and see!
- Paul Phoenix in Tekken starts out as the only guy powerful enough to ever end up in a draw against The Hero (sort of) Kazuya Mishima, and he's even designated as The Rival in the first game. However, as Tekken evolves and the Mishima family starts to take most of the importance of the story, Paul is slowly thrown out of the picture in the rivalry. He still sometimes considers himself Kazuya's rival, but he's largely ignored, especially since he now focuses his rivalry on a bear, or ensuring that Hilarity Ensues, along with his Bruce Lee Clone of a friend, Law. Paul technically won the third Iron Fist tournament (Tekken 3), since he was the one who beat Ogre. He didn't stick around after the fight, though, which meant Jin got the credit after beating True Ogre.
- Shogo: Mobile Armor Division, an early FPS game by Monolith (of earlier Blood and later F.E.A.R. fame) featured a Goldfish Poop Gang character named Samantha Sternberg, who would show up, try to kill you, promptly get blown to pieces, and come back again a few levels later for more. This was played for laughs in a plot that was otherwise reasonably serious (i.e. Samantha was the only character to inexplicably survive multiple encounters with the player, whereas nearly every other character would die when you destroyed their MCA). Notably, Samantha was determined to kill your character, whereas your character seemed to regard her as something of a weird annoyance, at least until she attacks you in an MCA while you're on foot.
- In Valkyria Chronicles, one of your soldiers, Edy Nelson, dreams of becoming a famous singer and actress. However, Rosie is already a fairly popular singer, which rouses Edy's jealousy and prompts her to view Rosie as her number one rival. Of course, Rosie is completely oblivious to said rivalry. Rosie's Big Sister potential allows her to be buffed if Edy is nearby. Edy's Rosie Hater potential allows her to be debuffed if Rosie is nearby. Put the two together and Rosie will be stronger than normal and Edy will be weaker than normal.
- Henry from No More Heroes. When he is first encountered, he kills the Rank 5 assassin Letz Shake before the protagonist, Travis Touchdown, has a chance to in a pre-organised fight. However, after the player defeats Henry in a final bonus battle, Henry reveals himself to be Travis's twin brother (although the ambiguous plot of the game means that this is not necessarily true).
- Inverse Example: Street Fighter IV has Rufus, an obese but agile American warrior who spends the tournament pursuing Ken. However, he doesn't know what Ken looks like beyond the vaguest physical description (blond hair, Caucasian, known to wear red) and is prone to mistaking others for Ken. Played straight in that Ken doesn't have the foggiest idea who Rufus is.
- "Dynamite" Dan of the Daiku no Gensan series views Genzo as his rival. Genzo barely even knows he exists, and views him as just another of the Kuromoku-gumi annoyances he has to deal with.
- In Iji, Komato Assassin Asha considers Iji to be his complete and utter nemesis after she beats him; Iji makes no comment except for a remark about being bountied. This changes after he kidnaps and later (possibly) murders her brother.
- Katamari Damacy has Kawaiiko Ichigo, who's incredibly jealous of how the King of All Cosmos calls her Dojikko cousin Honey cute. So far, there's no sign Honey is even remotely aware of their so-called rivalry — and given the series' nature, it's unlikely that's going to change.
- Paper Mario has Jr. Troopa, a baby Koopa Troopa that never left his eggshell. After being trounced by Mario in the first chapter of Paper Mario, he swears revenge, and returns to face Mario at the end of nearly every chapter. Goombario's tattle always seems to ridicule his persistence, and he never really plays any significant role in the plot. Mario's performance as the Heroic Mime adds much humor to Jr. Troopa's appearances and monologues. The player even has the chance to rub this in further before the second fight with him, as they can choose "No" when asked if Mario remembers him. Naturally, this doesn't please him.
- Final Fantasy:
- Gilgamesh and Bartz play this out in Dissidia 012: Final Fantasy. Bartz has lost his memories of his home world, and doesn't remember Gilgamesh, who shows up and demands a duel. The icing on the cake that Gilgamesh doesn't even seem to realize that Bartz has absolutely no idea who Gilgamesh is in this continuity; Gilgamesh misinterprets Bartz's look of confusion at his arrival as his being dumbstruck at seeing him again. Bartz only accepts his challenge because he feels it'd be a fun way to pass the time.
Gilgamesh: Steel yourself! For I am not the Gilgamesh you remember!
- Similarly, Gilgamesh doesn't seem to recognize Squall, Zidane or Vaan despite having encountered them as a boss during his rift traveling shenanigans. Not that they do either.
- Gilgamesh and Bartz play this out in Dissidia 012: Final Fantasy. Bartz has lost his memories of his home world, and doesn't remember Gilgamesh, who shows up and demands a duel. The icing on the cake that Gilgamesh doesn't even seem to realize that Bartz has absolutely no idea who Gilgamesh is in this continuity; Gilgamesh misinterprets Bartz's look of confusion at his arrival as his being dumbstruck at seeing him again. Bartz only accepts his challenge because he feels it'd be a fun way to pass the time.
- In Tales of the Abyss, Dist is not actually this to Jade, but Jade likes to pretend he is - mostly because it really, really annoys Dist, which Jade clearly finds hilarious.
- Lt. Carter Blake in Heavy Rain tries to see himself as a rival to Norman Jayden due to the fact that he dislikes and resents him like all cops. However, due to the fact of working together, Jayden doesn't acknowledge him as a rival.
- In Fallout: New Vegas, Ulysses is this to the Courier. Ulysses is obsessed with the Courier for destroying the budding nation in the Divide by delivering a package that caused the nukes hidden underneath to detonate. The Courier, however, is completely unaware of the part they played in those events and has no prior knowledge of Ulysses.
- In Baten Kaitos Origins, Giacomo is one to Sagi, after the Power Trio kicks his ass during the excape from Mintaka in the beginning of the game. Sagi, meanwhile, just feels sympathy for Giacomo's obsession.
- Team Fortress 2 invokes this trope with it's "Nemesis" gameplay mechanic. Specifically, if you kill another player 4 times in succession without being killed by them in return, you will be designated their nemesis and have a flashing icon displayed over your head. Only that player will be able to see this icon (and if they kill you, they receive bonus points) and it won't appear over their head when you spot them. And, even though the nemesis in question will be notified that they're dominating that player after the fourth kill, enemy players' names are not shown outside of the kill feed (except when disguised while playing as a Spy), often leaving the only way to identify a player you've dominated as being the guy who repeatedly charges you brandishing a melee weapon.
- Nancy Drew: The Captive Curse:
- One of the (many) criminals Nancy's put in jail vows revenge and tells her they will meet again. Nancy's response?
Nancy: Well, there's a waiting list. I hope you're patient. Goodbye, Anya.
- There's one case in the Nancy Drew games in which someone who vowed revenge actually attempted it. Dwayne Powers is the true mastermind in Nancy Drew: The Ransom of the Seven Ships. Slightly subverted, however- Nancy Drew remembered the actions of said individual, but she forgot the person's name.
- One of the (many) criminals Nancy's put in jail vows revenge and tells her they will meet again. Nancy's response?
- In Super Robot Wars UX, Doctor Minami regards Doctor West his greatest rival, but West has no idea who he is. It turns out Minami hates West because West doesn't know who he is.
- Touhou: Played with in dialogue between Alice and Reimu. When Alice re-challenged Reimu during the Extra stage of Mystic Square, the latter didn't remember who she was. This becomes a bit of a Running Gag: when Alice re-appeared in Perfect Cherry Blossom, Reimu still acts like she doesn't know who Alice is; during the Magic Route of Imperishable Night, Reimu doesn't even seem to acknowledge Alice is there with Marisa; and, she gets only slightly better treatment in the Tasogare fighter games in as far as dialogue is concerned, even though there is still never a formal addressal.
- In Dragon Age: Inquisition, Sera introduces herself by sending an invitation to the Inquisitor via arrow. When the Inquisitor arrives at the appointed time and place, they encounter a hostile Orlesian mage. The mage seems to think he's the Inquisitor's Arch-Enemy and that the Inquisition must have spent much of its resources tracking him down. Seconds later, Sera appears and plants an arrow right between his eyes. The Inquisitor (and player) never even learns his name.
- Parodied in Phoenix Wright: Ace Attorney:
- Butt Monkey Gumshoe announces himself to be Phoenix's rival, who is both confused and flattered — but mostly amazed.
- Even more so with Winston Payne, who is hardly remembered by Phoenix and completely ignored by fellow prosecutor Edgeworth.
- In Phoenix Wright: Ace Attorney – Dual Destinies, Phoenix's reaction to Gaspen Payne claiming that his older brother Winston is Nick's "longstanding rival" is suitably incredulous.
Phoenix: ("Longstanding rival"...? When were we ever rivals, let alone "longstanding"...?)
- In Fate/stay night, Issei considers Rin to be his arch-nemesis. Rin never responds to his enmity, which only makes him more suspicious and jealous. And on a less humorous note, Shinji has this going on towards Shirou, but this grudge reaches extreme levels fairly quickly.
- Little Busters!: Sasasegawa Sasami and Rin. Sasami interprets their constant battles as them being fierce rivals and takes them very seriously. Rin interprets their battles as Sasami being annoying and can never remember her name.
- Hatoful Boyfriend has Nishikikouji Tohri in Holiday Star and the drama CD. He's always trying to go after Shuu, and he's never able to even encounter him. Yuuya tells Shuu about one of his attempts, once.
Shuu: Nishiki...kouji... The client from four years ago? No, that's not right. The other witness from the third toucan trial... isn't right either, is it?
Yuuya: You really don't remember? It's rare for Iwamine-sensei's world-renowned preeminent memory to be so troubled.
Shuu: You're making too much of it. I won't remember each and every thing about anybirdie I have no interest in.
Yuuya: Somehow or another, it looks like Nishikikouji Tohri has some catastrophically one-sided feelings. Life doesn't always go as planned.
- Jango Fett from Darths & Droids is the Unknown Rival to Obi-Wan Kenobi, complete with Obi-Wan saying "Sorry? Do I know you?" as Fett prepares to gloat about his plans for revenge. Although unlike many of the other examples on this page, Obi-Wan really has never before met or seen Fett, or indeed had any inkling of the man's existence.
- Las Lindas has Alejandra to Mora. This is more a Deconstruction of the trope, since Mora doesn't really care and is more worried about keeping her farm up and running, Alejandra's near-overwhelming desire to crush Mora into dust mostly just harms her mental state and her company's reputation and financial state.
- The Order of the Stick:
- Main character Roy Greenhilt is the Unknown Rival of the Big Bad Xykon, who's vaguely aware that there's a guy called Redpommel or something who swore revenge on him for some reason or other. Even after Roy personally thwarts his plans and destroys his body and lair, the most he gets from Xykon is the page quote. Double Subverted later when Xykon makes a Call Back to his last encounter with Roy... except it was All Just a Dream. When Xykon actually faces Roy again in the desert, he's already forgotten everything about him.
- Interestingly, Redcloak, who isn't the Order's main target, actually recognizes them every time they meet, and even gives Xykon a recap of their previous fights to Xykon when they arrive at the pyramid. The Monster in the Darkness doesn't recognize them at first, but remembers the name of the Order, and when in the desert, actually recalls Roy (alias Flopsy).
- Also the case with Ian Starshine, who thinks his own plan to topple Tarquin is significant to the latter, to the point that he (falsely) believes that Elan was sent by Tarquin to infiltrate the Order of the Stick to get close to Haley and then, by extension, Ian himself. The real reason Ian was being held by Tarquin? Bozzok was paying him to. Other than that, Tarquin didn't care about him. Tarquin does later frame Ian for assassination, but it's over a petty argument and to "test" Haley, more or less the opposite of what Ian imagined. Although Tarquin does state he vaguely remembers Ian at one point (but not his name), so he may be partially right.
- In The Wotch, Cassie is this to Anne. Anne is oblivious to most of the goings-on in her world and just sees Cassie as a friend, not realizing that she's jealous about Robin's affection and Anne's magic power, which Cassie thinks Anne did nothing to earn. Though Cassie later wins Robin, she's still upset about the magic thing.
- In Something*Positive, Ollie sees Davan as his Arch-Enemy. Davan wasn't even aware that Ollie hated him until Ollie recently confronted him and declared that they were enemies. This is because Ollie blames Davan for derailing Ollie's theater career years ago when it was really Ollie's own incompetence that did it. Davan is actually a bit upset by this.
- Van Von Hunter has a recurring character named Vengeance Joe who swears revenge against the title character... for failing to introduce himself when they passed on the street.
- Bravoman: Anti-Bravoman tries to play himself up as a dark anti-heroic rival to Bravoman, who goes about without noticing him, when he does find Anti-Bravo, he befriends him and still remains ignorant to Anti-Bravo trying to set up a rivalry. When Bravoman goes to an alternate Dimension where Anti-Bravoman has leveled the world all in the pursuit of power he tells Anti-Bravoman that he can be a real threat, and to keep up the good work.
- Inverted in Shortpacked!, Sydney Yus has a whole speech about how Galasso will remember her now, which she insists on saying despite Galasso making it clear that he knows exactly who she is and always saw her as his most dangerous enemy.
- Played straight in Cosmic Dash where the space pirate Vid Seng, and by extension his larger crew, has a rivalry with Dash Kameku and his cohorts. Dash doesn't see Vid so much as a rival but more of an annoyance... when and if he remembers him.
- In Dumbing of Age, Becky sees Dorothy as her implacable rival for Joyce's affections. (Platonic affections; Becky is gay and in love with Joyce, but knows that both she and Dorothy are straight.) Dorothy sees Becky as another of Joyce's friends, who's a bit weird around her for some reason.
Becky: So for tonight, a truce?
Dorothy: A truce from what?
Becky: That's the spirit.
- Nebula: Jupiter devotes the majority of his waking moments to trying to find a way to kill Sun and take his place as leader. Because he's incredibly obvious about it, Sun knows, but finds him to be so little of a threat that he's just vaguely concerned about the possibility of Jupiter injuring himself in the course of a Zany Scheme to try and kill him instead of holding him as any sort of serious rival.
- In Welcome to Night Vale, Cecil will express disgust with the rival town Desert Bluffs whenever they come up in his broadcast and will go on about how awful it is. When Night Vale comes up in Kevin's broadcast to Desert Bluffs, however, he makes no mention of any negative feelings between the towns and says that he bets Night Vale is wonderful and beautiful.
- Cecil also very vocally declares his disdain for his supposed Sitcom Arch-Nemesis Steve Carlsberg. Steve is actually the human personification of a puppy dog, and treats Cecil with happy excitement.
- Dr. Horrible's Sing-Along Blog: Not quite unknown, but Dr. Horrible does go out of his way at one point to emphasize to Johnny Snow that they are not nemeses and that Snow is barely a blip on his good-guy radar. A prequel comic reveals that Snow is a wannabe hero who attempts to stop the Evil League of Evil from poisoning the city's water supply while Captain Hammer is out of town. Instead, he uses his Freeze Ray (different from Horrible's freeze ray) to turn the water supply to ice. The League figures that Snow has done their job for them and goes home.
- PC Gaming magazines seem to be full of articles about why consoles are vastly inferior to PC. An issue of PC Gamer had an article on building a perfect gaming rig for under $600, which concluded with the line "Take that, consoles!" This seems to be a fairly one-sided sentiment on the part of PC gamers. For the most part, people that prefer consoles don't really see a rivalry with PC.
- Back when it was still a parody magazine, Cracked relished in taking pot shot after pot shot at MAD. Not once did MAD ever even acknowledge that Cracked existed. This was averted in Real Life, as MAD publisher William Gaines was so acutely aware of knockoffs that he had a voodoo doll in his office, and each pin was labelled with the name of a different magazine. To Cracked's credit, theirs was the only pin left in the voodoo doll by the time Gaines died in 1992.
- A variant in Kung Tai Ted. After being attacked by a hitman sent by bitter rival Solomon in his The Angry Dragon review, Ted pledges to find and defeat him. However, he takes so long in doing so that by the time he manages it in Golden Ninja Warrior, Solomon has long since forgotten about him.
- In the Let's Play of Princess Maker Lizzie Shinkicker earned the rivalry of Wendy because her magic prowess was slightly better then the rest. Every encounter with Wendy was hilariously short, as Wendy was a Squishy Wizard and Lizzie was well-rounded enough that she could often defeat Wendy in one hit from her sword. Cube even comments on Wendy's desire to beat Lizzie as a "suicidal delusion."
- TV Tropes versus Wikipedia (That Other Wiki if you're feeling bitter about it) with TV Tropes as the unknown one.
- True Capitalist Radio has Ghost's enthusiastic and entirely one-sided vendetta against Alex Jones.
- There's a couple of cases in the Whateley Universe.
- One is Phase and Golden Girl- Golden Girl wants to be the boss of her martial arts class, but Phase continually blows her out of the water by combining his weapons, his damn good powers and his gift for strategy. Phase really doesn't care about Golden Girl beyond 'she's an occasional annoyance', because he has real problems to deal with, while Golden Girl despises Phase utterly.
- Another is Nemesis and She-Beast - She-Beast's father, Dr Diabolik, attacked a city and ended up killing over a hundred people, one of whom was Nemesis' grandfather. Nemesis blames Jadis personally, and Jadis' only response to her declaration of war was 'Take a number and get in line, bitch.'
- Anthony "A-Log" Logatto is this to Christian Weston Chandler; A-Log gained notoriety for his commentaries on Chris-Chan's videos, and would also wish harm towards Chris for, among other things, "giving autistics like him a bad name". Despite this, Chris doesn't know who A-Log is.
- The Nostalgia Critic invokes this trope when he made a video telling The Angry Video Game Nerd to stop letting his fans draw comparisons between them.
Critic: So, please, leave this petty, jealous rage behind you and simply acknowledge that I'm the better man. If you accept this defeat, please respond by leaving absolutely no comment whatsoever. In fact, don't even respond to this video. In fact, act like you have a million other things going on in your life that you wouldn't even have time to WATCH this video, let alone respond to it. Do that, and I will accept your apology.
- In Dragon Ball Z Abridged, after the Freeza saga, there's a Running Gag of the villains either not knowing or not caring about Vegeta.
- The Venture Bros.:
- The Monarch considers Dr. Venture his mortal arch-enemy and embarks on several attempts to kill him and his sons for no particular reason. Through most of the first season, the Ventures repeatedly undercut the Monarch's claims to be their most hated foe. By the end of the second season, however, their status as nemeses has become much more solidified, though Dr. Venture still doesn't really care for him.
- Henchman 21 is convinced that he is destined to destroy Brock Sampson, who almost always responds to 21's exposition with "Who are you again?"
- Leonardo Leonardo in Clerks: The Animated Series, whose plots against the clerks were always inadvertently defeated, even though they didn't realize (or, more likely, didn't care) he considered himself their sworn enemy. ("Well played, clerks, well played!")
- Harvey Birdman, Attorney at Law: X the Eliminator started out as a villain hired to steal Birdman's crest. After years of failure, X becomes an obsessive stalker, initially unknown to Birdman.
- In Rocky and Bullwinkle, the protagonists seem completely unable to recognize the show's only recurring villains, Boris and Natasha. It helps that the villains are spies who deliberately try to stay covert, and they typically only meet the heroes face-to-face in disguise (paper-thin or otherwise; doesn't matter too much when the heroes wouldn't recognize you if you were wearing no disguise at all.) Rocky occasionally remarks that he recognizes Boris' voice, but that's the closest they ever get to remembering the villains between episodes. This even continues into the movie!
- In Transformers Animated, Megatron has this towards Optimus Prime. He knows who he is, and might have a certain degree of respect for him, he just can't be bothered to learn Prime's name. Megatron saw the Autobots in general as his enemy rather than having a specific nemesis - not even Ultra Magnus as the Autobot leader. He never even calls them by their names unless he has to. It's only by the final episode that Megatron develops a very personal beef with Optimus for thwarting his plans, thus establishing the true rivalry they're famous for.
- When The Transformers Megatron creates a clone of Optimus Prime (which he controls by remote control) and tries to use it to infiltrate the Autobot base, this nearly gives him away. He calls the other Autobots by the wrong names (like addressing Ironhide as "Bumblebee") and acts like he barely knows them, causing them to quickly become suspicious.
- Billy Billions, from Ben 10: Omniverse, has spent a quarter of his life scheming and vowing revenge against Ben for the horrible crime of being more popular than him in grade school. After an attempt to send Ben to Dimension 12 ended up with him going there instead and spending five years in a wasteland, he returns to earth and claims that he is Ben's Arch-Enemy and final destroyer. Ben never even knew he existed.
- The original Hunter from Gargoyles wanted to kill Demona as revenge for slashing and scarring his face. During his final fight with Demona, Demona confesses that she doesn't even remember that act, that's how insignificant it was to hernote . The later Vinnie Grigori pursues Goliath throughout the episode "Vendettas", wanting revenge on Goliath and the Manhattan Clan for unknowingly causing a lot of trouble for Vinnie. He ends up shooting Goliath with a cream pie, then walking away with Goliath still having no idea who he is.
- Teen Titans has Control Freak, he thinks he's an important villain, but the Titans don't think much of him. He even calls the Titans "my old arch-nemesis...es" the first time they meet. He is rather peeved when he's not put on the "list of notorious villains" and the Puppet King is.
Control Freak: They only fought him that one time! I'm a recurring villain!
- Barry from The Tick, who is annoyed at the titular hero for having 'stolen his superhero name' while the Tick doesn't take him very seriously at all (and considering the things the Tick does take seriously, that's saying something).
- The Box Ghost from Danny Phantom.
- The Simpsons:
- Not quite enemies, but in "Who Shot Mr. Burns?", Mr. Burns is perpetually unable to remember his employee Homer Simpson. Eventually Homer breaks into Burns's office and writes his name on every wall in giant letters, then attacking Burns and shouting "MY! NAME! IS! HOMER! SIMPSON!" at him. Afterwards, Burns has this to say to his manservant:
Burns: Smithers, who was that cow just yelling at me?
- The situation is different when Homer changes his name:
Burns: Ah! Max Power! How's every little thing?
Homer: You remembered my name!
Burns: Well, who could forget the name of a magnetic individual like you? Keep up the good work, Max!
- Homer experiences the other side of this trope with Frank Grimes, who hates Homer's guts, while Homer thinks they're friends, but only in the first act. And then his son, who takes revenge on Homer, "How is old Grimey?"
- Not quite enemies, but in "Who Shot Mr. Burns?", Mr. Burns is perpetually unable to remember his employee Homer Simpson. Eventually Homer breaks into Burns's office and writes his name on every wall in giant letters, then attacking Burns and shouting "MY! NAME! IS! HOMER! SIMPSON!" at him. Afterwards, Burns has this to say to his manservant:
- Celebrity Deathmatch:
- There's a weird variation on this in an early episode, in a match between Bill Gates and Michael Flatley. What was the reason for the match? Well, at first, even they had no idea. (Each admitted they had no grudge against the other.) Right before the fight, however, the Nick and Johnny found out it was due to a clerical error in the scheduling. Still, why not? They simply called it "The Battle of the Clerical Error".
- Played straight in one Halloween Episode where an undead Stacy Cornbread came back leading an army of zombies to get revenge on Debbie Matenopoulos, claiming Debbie had stolen her job. The biggest thing wrong with this was that it wasn't Debbie's fault; she hadn't even appeared on the show until several episodes after Stacy's death and had never even mentioned her. Still, if Stacy came looking for a fight, she certainly got one; Debbie was only too willing to kill her again.
- Mr. Turner to Mr. Dinkleburg in The Fairly OddParents. In a few episodes, however, it's implied that Dinkleburg actually is aware of the rivalry, he's just a heck of a lot more subtle about it, preferring Conspicuous Consumption, with the added implication of "If you never had your son Timmy, you could of had all this money to spend too!"
- This is more due to Flanderization than anything. In an early episode Timmy actually seems confused about his parents dislike of the Dinkleburgs even claiming that they are nice.
- In "Operation Dinkleberg" he makes a big deal of acting like a supervillain for Mr. Turner, because he knows how much it means to his neihbor to think he's evil.
- Kim Possible:
SSJ: We are being followed! It is Kim Possible, and her sidekick-type-friend whose name escapes me.
- Dr. Drakken can never remember Ron Stoppable's name — although he may have just trouble with sidekicks in general, as seen when Kim teamed up with her mom:
Dr. Drakken: And so, Kim Possible and her... sister?
Dr. Possible: Is he hitting on me?
Kim: No, sidekicks really confuse him.
- This is something of a recurring theme among Kim Possible's enemies. The only ones who can remember Ron's name are the Seniors, and that's only because they ASKED. They're polite that way.
SSS: (leaning out the helicopter window) What is your name again, young man?
Ron: It's Ron! Ron Stoppable!
SSS: That's it!
- Monkey Fist remembers Ron too, but then he's more Ron's enemy than Kim's in the first place.
- Professor Dementor seems to regard Dr. Drakken as a second-rate wannabe, though at least he remembers Drakken's name.
- Dr. Drakken can never remember Ron Stoppable's name — although he may have just trouble with sidekicks in general, as seen when Kim teamed up with her mom:
- In the Where's Waldo? animated series, Waldo and Wizard Whitebeard are completely unaware of Odlaw's existence.
- Dr. Destiny in the Justice League episode "Only a Dream". When the Justice League originally busted him, he was just another of LexCorp's many mooks. He wants revenge for this. They have no idea who he is, or why he's so intent on killing them.
- In The Spectacular Spider-Man, when Spidey unmasks Mysterio as Quentin Beck:
Beck: So now you know, it's me.
Spider-Man: Right, um, who are you again?
Beck: You put me away!
Spider-Man: Wow, really? Heh, cool!
Beck: Don't pretend you've forgotten, I was the Chameleon's right hand man!
Spider-Man: Oh right, on the boat! You were...dressed as the crewman!
Beck: As the waiter!
- On Jimmy Two-Shoes, the eponymous character considers Lucius a friend. This is because he's such a pollyanna that he's completely unaware of just how much he is loathed by him.
- The title characters of Phineas and Ferb usually have no idea they're doing anything wrong with their outlandish projects, so they don't seem to understand why their older sister, Candace, is so dead-set on getting their mother to see them. They even help her sometimes, unaware that her goal is to get them grounded for as long as possible. The fact that their father and every member of their extended family except their mother is occasionally in on them probably has something to do with it.
- For Making Fiends, Cheerful Child Charlotte is completely unaware of Alpha Bitch Vendetta's hostile attitude toward her.
- South Park:
- In the episode "Crippled Summer" Nathan is this to Jimmy.
- Cartman is this to Wendy in "Dances With Smurfs". He regularly calls her out and shames her publicly only for her to...go about her business. Everyone but Wendy sees this as a big deal. It's not until the end of the episode that she responds and she absolutely destroys him.
- Likewise, in "Tom's Rhinoplastry," Ms. Ellen has no idea that Wendy sees her as a jealous rival for Stan's affections to the point where Wendy arranges for Ms. Ellen to be captured by Iraqis and launched into the sun. A shame Wendy never realized Ms. Ellen was a lesbian.
- In some episodes of Spongebob Squarepants, the titular character doesn't seem to acknowledge Plankton as an enemy.
- On Doug, the titular character thinks of Guy Graham as a rival, particularly because Guy also has his sights set on Patti Mayonnaise. However, Guy is completely unaware that he's such a burden to Doug.
- On Hey Arnold!, Helga is this to Lila, since Arnold has a crush on Lila while Helga has a crush on him. Her rivalry with her sister Olga falls into this as well.
- Used in the Futurama episode, "A Taste of Freedom" when Fry, Leela and Bender ready their secret weapon against the invading Decapodians.
Fry: You haven't won yet, Mervin! You didn't expect us to even go to a museum, much less steal this ancient heat-seeking missile.
Ambassador Mervin: I don't even know you.
- In Foster's Home for Imaginary Friends, when Duchess reveals herself to Bloo and talks about her plan to get rid of him, it takes a while for him to figure out who she is and why she hates him. He's even apologetic when he does.
- In the Adventure Time episode "Duke of Nuts", a red squirrel hates Jake because Jake never prints the squirrel's letters in his advice column. The squirrel considers Jake his mortal enemy, while Jake has no idea the squirrel even exists. When the squirrel appears again in the season five episode "Princess Potluck", he is even more fixated on Jake, and Jake still doesn't know who he is.
Squirrel: You son-of-a-blee-blob! JAAAAKE!
- In Max Steel, minor villain Woody Barkowski claims he is Max's Arch-Enemy. Max snarks that he barely qualifies as comic relief.
- Dr. Claw is so focused on Inspector Gadget that he and most of his cohorts pay barely any attention to the meaningless blonde girl who actually solves all the crimes (that is, Penny). Lampshaded in the 2015 CGI version, where Talon (the one member of MAD that does know who Penny is) sees her on his security camera and points her out to his uncle Claw, who in turn says that he has no idea who she is or why Talon is suddenly so obsessed with low-value coins.
- In Over the Garden Wall, Jason Funderberker seems unaware that he and Wirt are both interested in Sara, or else is really mellow about it.
- Steven Universe: In "Beach Party", the Gems barely even remember the restaurant they've been banned from exists, nor do they care on account of not needing to eat (Amethyst, the only one who likes to eat, says the pizza isn't that good, anyway). Even at the end, they cannot recall what store the family owns after being unbanned.
- In March 2009 New York Radio station WXRK changed from a rock format to Top-40. They then immediately positioned themselves as the The Rival to established Top-40 station Z-100. Since then they've been bashing Z-100 constantly in commercials, including a shameless ripoff of Mac's "I'm a Mac, I'm a PC." ads, and a spot accusing them of supporting hip-hop artist and domestic violence accusee Chris Brown. If Z-100 has noticed, they have yet to show it.
- This happened briefly in Seattle too in the mid-'00s. A new alternative station popped up with a lineup of DJs that was almost exclusively formerly with the alternative station that had existed in Seattle for around a decade and a half at that point, and their ads and listener testimonials repeatedly made a point of noting how the more popular alternative station sucks now. The more popular station never, ever acknowledged their existence and the upstart alternative station was gone within a year.
- Almost every political assassination. Bobby Kennedy's last words might as well have been "Who are you?"
- Uwe Boll is reportedly trying to start a rivalry with Michael Bay. Bay is unimpressed. It got to the point where Boll challenged Bay to a 12-round boxing match, and Bay responded by saying that he'd "never even heard [Boll's] name till last week when he made threats and rants" and called him "a fucking idiot".
- Enver Hoxha of Albania was pretty much this to the communist world in the Cold War, having split off ties with Tito's Yugoslavia, the Soviet Eastern Bloc and the Chinese led third world for not being hardliner enough. Albania would go on to build numerous bunkers around the country out of fear of an invasion that never came. Needless to say, his more successful rivals didn't care much for invading.
- Subverted between Noah Antwiler and Dixie Carter, Dixie shot back at Spoony multiple times, for no real good reason either. Due to differences between regional dialects, he had no idea what she was even trying to say to him until Angry Joe and others translated for him.
- This trope is invoked in any of the Warner Bros. cartoons that lampoon Disney. The studio was an easy target for two reasons: firstly because everyone was familiar with Disney, and secondly because Warner Bros. knew that Disney didn't really care enough about the "rivalry" to make fun of them back.
- British comedian Jack Whitehall describes himself as this to Twilight's Robert Pattinson, he claims to have had a one-sided rivalry with Pattinson since high school. This is one of the few examples where the unknown is well aware that the object of his rivalry doesn't notice or care.
- In the First-Person Shooter genre of video games, the developers of the Battlefield games view themselves as rivals against Call of Duty and want to take their throne as King of FPS games away from them. This has created a chasm between Battlefield fans and Call of Duty fans where the former claim that their games are a more unique FPS and CoD is generic and doesn't deserve all the sales and popularity it has as a franchise. Call of Duty's response? Its developers were quite surprised to hear that developers and fans of the Battlefield games even care all that much about it and doesn't see why the two franchises can't learn from each other and make the industry as a whole stronger.
- The relationships between the three big video game makers, Nintendo, Sony, and Microsoft is very interesting, as none of them seem particularly interested in each other.
- Nintendo pays the other two little to no mind, Microsoft generally advertises as being the best option without acknowledging the other options, and Sony, interestingly enough, advertises as being the best, but doesn't mention what they're the best at. Except for the Xbox Kinect and Playstation Move being deliberately designed to capitalise on the success of the Wii.
- An interesting example of this happened with the reveal of the Xbox One and Playstation 4. When fans complained about many of the features of the Xbox One, Microsoft responded with a very "take it or leave it" attitude and basically said that the customer would have to either buy an Xbox One or be stuck in the past. When Sony took advantage of the bad press and based their E3 presentation around unfavorably comparing the One to their PS4 and emphasizing that the PS4 would not have the same controversial features, Microsoft seemed to suddenly realize they have competition and backpedaled on nearly every infamous feature they'd announced.
- The Entertainment industry seems to have a bone to pick with the Internet. Justified, as there's much piracy and whatnot going on online. The users of the internet in general couldn't care less... until they tried to force through SOPA, PIPA, and ACTA, that is. And even ACTA wasn't that well-known until the controversy surrounding SOPA and PIPA in the U.S. got people worldwide to take notice.
- World of Warcraft Vs. Whoever's Number #2 on the MMORPG list right now.
- North Korea had been constantly threatening the United States and South Korea with nuclear war early in 2013. Judging by the comments on news stories about these threats, most Americans were unaware why North Korea was suddenly so angry at them and were not at all intimidated. In general, the entire justification for their military government is the "inevitable" American invasion, when America has barely thought about them for 50 years and has no reason to do so. This specific case appears to have been something the NK leadership made up so that after the posturing they can claim the Americans backed down.
- In the late 19th Century, the thought of annexation by the US was a huge issue to Canadians.
- Politicians won elections campaigning against it, political cartoons were circulated in Canadian newspapers depicting Canada or Britannia kicking Uncle Sam to the curb, etc. Meanwhile, most Americans weren't focused on Canada, caring much more about the Civil War, the conflicts with the Native Americans, and military interventions in Central America. There were only two times that the United States actually made any attempt toward annexing Canada: once during the War of 1812, and once before the US technically existed. After that, US expansion was uniformly aimed westward, not northward.
- The leading Canadian politicians of the era were Genre Savvy enough to keep the state of affairs firmly in this trope. Their goal was to make sure that the United States did not start looking north as a direction for expansion. The Northwest Mounted Police were established primarily to make sure that Canada could justify its claims over the areas that would become Alberta and Saskatchewan and a transcontinental railroad was built to solidify this claim. However, Canada never tried to claim any territory to the south which was claimed by the United States. This resulted in any Americans who tried to look north to quickly decide that it would be too much of a headache when they could go west instead.
- This still shows up in the way the War of 1812 is covered in history books in respective countries. From the Canadian perspective, this was the conflict in which Canadian farmers beat back Yankee invaders and burned down the White House in revenge (rather inaccurately, since the forces that raided Washington were British regulars with hardly a Canadian among them), while very few people in United States know much about this war. Those that do saw the British as their primary enemy in the war, and the casus beli as British impressment of American sailors. The British don't even remember ever fighting it; it was a sideshow for their series of wars with Napolean.
- When Hugo Chávez was alive, he fancied himself and the "Revolution" he led in Venezuela as the biggest enemy of the USA, deprecating the "Empire", rejecting American humanitarian help, antagonizing with every American functionary he could and insulting whoever was the States' President at the time. Suffice to say, the feeling wasn't mutual. The thing was perfectly summed up in a political cartoon◊ which depicts Chavez as a gas station employee insulting car driver George W. Bush while the latter says "Yes, yes, whatever you say... fill up the tank, buddy!" His successor as President of Venezuela, Nicolás Maduro, has continued the pattern.
- Several political analysts see the traditional anti-American feeling prevalent in South America as a form of this trope. While not denying the controversial policies applied in the region, and the justified hate several citizens of certain countries have against USA, the truth is that more often than not the countries that obsess the most against the USA tend to be the ones who have had the least direct American intervention during their history. Most Americans don't even know about it.
- When it was discovered that "One Direction Day" and the Doctor Who 50th Anniversary were on the same day, some of the band's fans were quite upset, going so far as to demand that Doctor Who change the date of the Anniversary Special and claim that One Direction had somehow "picked the day first." Doctor Who fans just either laughed at them (if they were being generous), or asked who One Direction was.
- Since they weren't invited to the treaties that ended World War I, Andorra was technically at war with Germany for 25 years without Germany noticing. Better yet, America was invited but didn't sign, meaning technically, America was still at war with Germany until they later signed a separate peace agreement. Similarly, Teddy Roosevelt forgot to invite representatives from Montenegro to the peace conference to end the Russo-Japanese War that he was hosting at Portsmouth because he did not realize that Montenegro declared war against Japan in a show of solidarity with Russia.
- Sarah Palin would be this to President Barack Obama. Despite actually calling for his impeachment (which often tries the patience of members of her own party) he rarely even acknowledges a thing she says, brushing off the few questions interviewers ask him about her.
- Conspiracy Thoerist and "birther queen" Orly Taitz is this as well. Despite her numerous legal challenges (none successful and most of them fruitless) to challenge President Obama's eligibility, he has yet to even acknowledge or respond. Few politicians or courts take her seriously; even conservative commentator Bill O'Reilly has called her "a nut".
- This happens between members of the "birther movement", including Orly Taitz, Donald Trump, and Sheriff Joe Arpaio. It's doubtful he even cares about the accusations they make against him that never go anywhere. Every U.S. President tends to treat conspiracy theorists who target them as beneath notice.
- There's John Boehner's attempt to sue the president. Needless to say the president doesn't seem to have even noticed this, let alone actually care (he certainly hasn't felt the need to comment).
- In the U.S., members of the the Green Party really, really hate the Democratic Party, despite the Greens being very similar ideologically to the left wing of the Democrats. The Democrats almost never mention the Greens.
