The "CynicIdealist Duo" is a duo of close characters (either best friends, siblings, or teammates) that show contrast between their ways of seeing the world: one of them is The Cynic, a character who views the world in a negative way, while the other is The Idealist, a character who has faith and hope on the goodness of the others.
Although the duo has different ways of viewing the world, they are extremely close to each other. However, it doesn't stop them from bickering/fighting in a Conflict situation, mostly invoking the Sliding Scale of Idealism vs. Cynicism trope (heroic ex: They bicker because they don't know if they should shoot down the villain or try to convert him/her to the good side, or one of them will call them out of an idea they consider "risky"). The Idealist may be a Wide-Eyed Idealist, and the Cynic may be a Grumpy Bear. The idealist may say Silly Rabbit, Cynicism Is for Losers! while the cynic may say Silly Rabbit, Idealism Is for Kids!.
Can overlap with Red Oni, Blue Oni, Odd Friendship (if it's a best friend duo), Sibling Yin-Yang (if it's a sibling duo). See also Four-Philosophy Ensemble, which adds Realist, Apathetic, and/or Conflicted to the mix.
Anime and Manga
- In Negative-kun to Postive-kun, we have the titular characters, grumpy pessimistic Jun Fujiwara and cheery perpetually optimistic Shin Tachibana, who are boyfriends.
- Just about anytime The Punisher has to work with another hero (with the possible exception of Nick Fury), Daredevil and Spider-Man being the more obvious cases. Frank won't kill another hero, but he will make his opinion on their Thou Shalt Not Kill attitude (and the Joker Immunity it causes) very clear.
- The Wicked + The Divine: Cassandra is the Deadpan Snarker pessimistic one to Dio's idealist with a bit of Messianic Archetype. The trope is subverted in that someone says Cass, despite her attitude, is actually an idealist and expects people to do the right thing.
- Whenever Superman and Batman have to work together (which tends to happen often), Superman is obviously the idealist, while Batman is the cynic.
- In The Apprentice, the Student, and the Charlatan, Twilight Sparkle serves as the more idealistic protagonist compared to cynical counterpart (and Love Interest) Nova Shine.
- Half Past Adventure: Pugliacci and Bulcinella, a pair of mobsters from the Crystal Dimension, form one of these, with Bulcinella frequently exhibiting a lackadaisical attitude and attributing things to "the universe", much to Pugliacci's dismay.
- The Mountain and the Wolf: Briefly happens during the Wolf's time as Tyrion's bodyguard. Tyrion is by no means a Wide-Eyed Idealist, but the fact that he believes in Daenerys as a fair and just ruler clashes with the Wolf's assertion that she has the qualities needed to make a fine warlord. It culminates in a screaming argument which the Wolf loses, possibly because he realizes he was about to let slip that he was responsible for Daenerys setting King's Landing on fire.
- Morgan Freeman (cynic) and Brad Pitt (idealist) in Se7en. Their respective characters, Agent Somerset and Agent Mills, are two homicide detectives. However, Somerset is a close-to-retirement veteran who thinks the world is a shit place full of inexplicable misery, while Mills is a young, motivated cop with a lot of fire in his belly who believes he can make the world a better place. Ultimately, Mills' mind is broken by the murder of his wife and he's manipulated into becoming a murderer himself, while Somerset decides to stave off retirement because he's realized that while he may live in a Crapsack World, trying to make it better is still worth it.
- Nick and Judy from Zootopia. Thanks to the Fantastic Racism against foxes, Nick became a bitter and cynical Con Artist, whereas Judy starts out as a Wide-Eyed Idealist whose intention is to "make the world a better place".
- Nero Wolfe and Archie Goodwin of the long-running detective series tend to have this kind of dynamic. Wolfe tends to be the grumpy, misanthropic old recluse with little interest in or goodwill towards the world and the people in it, while Archie is the cheerful, friendly, and good-natured man-about-town who embraces life to the fullest. That said, neither is exactly stuck at the extreme end of either side of the scale; there's hinted to be an old-fashioned romanticism deep down under Wolfe's crusty exterior, while Archie tends to adopt a kind of seen-it-all snark as a way of protecting himself against the world when things get tough.
- Commander Vimes and Captain Carrot have this dynamic in the Discworld novels, and Carrot also has it with Captain Angua. Vimes is possibly one of the most cynical people on the Disc, which is saying something, and Angua spends a lot of time in an Only Sane Man Deadpan Snarker role. Carrot, meanwhile, is idealistic and trusting to a degree that would normally get someone in Ankh-Morpork killed in ten minutes, but for him, it works.
- Dash & Lily: The titular characters. Dash is a cynical, brooding, Christmas hater with divorced parents and who has suffered a recent heartbreak. Lily is an optimistic, free-spirited Christmas lover with a tight-knit family and who has never been in love. They prove more than a match for each other.
- During their time on The Daily Show and The Colbert Report, Jon Stewart and Stephen Colbert invoked Irishman and a Jew, with Colbert as the idealistic Irishman, and Stewart as the cynical Jew.
- Rumpelstiltskin/Mr. Gold and Belle from Once Upon a Time operate as this as a couple respectively. Rumpelstiltskin is a Manipulative Bastard sorcerer that has faced such hardships as having his destiny of becoming a savior literally cut away from him by his insane mother, abandoned by his neglectfully-abusive father, permanently crippling himself so that his son would not grow up without a father like he has and branding himself as a Dirty Coward for the rest of his life and nearly losing his own son to be drafted in a hopeless war against the ogres before taking on a curse that imbues him with powerful dark magic at the cost of his humanity. Top that with losing his son to another realm due to his own cowardice, Rumpelstiltskin has little faith in himself and the goodness of others, viewing himself as a monster and believing in things like "love" in a purely rational, detached context. Belle, having spent her whole life reading about adventures and great things heroes do, believes in things like second chances and self-sacrifice, giving up her own freedom to Rumpelstiltskin in exchange for her village's safety and eventually seeing the lonely man beneath all of the darkness. While he rejects her and throws her out when he believes that she is just trying to manipulate him, he (as Mr. Gold) eventually reconciles with her after they are reunited. While their differing views have caused their relationship to falter and fluctuate as the series progresses, they eventually receive their Happy Ending in Season 7, Rumpelstiltskin having clearly changed for the better after she dies of old age in the Edge of Realms.
- The two main protagonists of BoxxyQuest: The Gathering Storm form one of these Catie is the idealist, and Anonymous is the cynic.
- Wandersong features an all-loving, idealistic, and pacifistic Quirky Bard teaming up with Miriam, a snarky, pragmatic Action Witch with a heart of gold.
- Cyberpunk 2077: Subverted. Johnny is both the idealist and the cynic among the protagonists. Where V is completely uninterested in anything beyond the next job, paycheck or thrill, Johnny is deeply committed to his anarchist, anti-corporate values. However, V is a generally happy, reasonably well-balanced individual with a wide circle of True Companions, where Johnny is a bitter, egocentric douchebag whose abrasive personality and unrelenting unwillingness to compromise his ideals has alienated pretty much every friend he ever had.
- In Nikolai's route of Queen of Thieves, one of the key elements of the romance between Nikolai and the heroine is the contrast in their outlooks. Nikolai, the Mastermind of the story's Caper Crew, sports a serious pair of Jade-Colored Glasses and on more than one occasion expresses a very low opinion of humanity and the world in general. The heroine, on the other hand, has a much more positive, romantic outlook - when Nikolai, baffled by her capacity for positivity, challenges her on her idealism, she shoots back in no uncertain terms that it's not that she's never experienced the harder part of life, it's that she chooses to focus on good things and be happy rather than dwell on the bad.
- RWBY: In Volume 7, Clover and Qrow are paired together for missions. Qrow is cynical, depressive and prefers to work alone while Clover is upbeat, chatty and prefers working with a team. Qrow's misfortune Semblance is uncontrollable and causes constant inconvenience for himself and others, while Clover has a controllable good fortune Semblance which aids him in combat. They both have a history of Undying Loyalty to a morally grey Huntsman leader: Qrow for Ozpin and Clover for Ironwood. However, when both Ozpin (in Volume 6) and Ironwood (in Volume 7) become Broken Pedestals to the heroes, Qrow and Clover's drastically different reactions drives an insurmountable wedge between them: Qrow turned on Ozpin, losing all faith in both Ozpin and his mission whereas Clover retains his loyalty to Ironwood and continues to obey him unquestioningly.
- In xkcd, a beret-wearing scone-obsessed Cloudcuckoolander existentialist and Cueball (usually filling the shoes of a nihilist) are often paired with each other in comics.
- Wander and Sylvia from Wander over Yonder. Wander is the idealist, always seeing the good in others, even the bad guys, and will never resort to violence. Sylvia is the cynic, worried that Wander is being too naive and that his do-gooding will get him in trouble; also, when it comes to villains, she's all too happy to let her fists do the talking.
- Dipper and Mabel from Gravity Falls. While Dipper doesn't have an excessively negative outlook, he does tend to be slow to trust anyone unfamiliar to him (and he is not helped by the craziness of his surroundings, either), especially in contrast to Mabel, who has a much brighter demeanour and is rather naïve and unsuspecting to the point of being an All-Loving Hero.
- Rapunzel and Cassandra, of Tangled: The Series. However, by the time we're introduced to her, Rapps has managed to make Cassandra a little more optimistic than she used to be, so they're more of a Realist-Idealist Duo.
- The Oracle Twins from American Dragon: Jake Long are a Played With example. Sara is bubbly and cheerful as a result of seeing only negative visions about the future (so she's got the powers of a cynic with the personality of an idealist). Her twin sister Kara is gothic and deadpan, because she only sees good things about the future (so she has the powers of an idealist with the personality of a cynic). This is explained as Sara seeing the positive things in life to compensate for her bad visions, while Kara has all the joy and surprise sucked out of life because she knows the good things that will happen.
