Wide-Eyed Idealist



""With kindness comes naïveté. Courage becomes foolhardiness. And dedication has no reward. If you can't accept any of that, you are not fit to be a magical girl.""

- Homura Akemi, Puella Magi Madoka Magica

A character who is far too idealistic for his or her own good.

It may be the Naive Newcomer who Jumped At the Call—he or she has a huge stack of comic books/movies/bards' tales, and thinks they're pretty Genre Savvy. Unfortunately, their universe is more toward the cynical end of the Sliding Scale of Idealism Versus Cynicism than the stories they know. Alternatively, they might just be generally nice people whose idealistic attempts at solving the problems of their world turn out to go horribly horribly awry as no one else plays by their rules. Usually used as nothing more than a device to highlight the realism/grittiness/cynicism of the setting.

This character either becomes a victim of Trauma Conga Line or Break the Cutie, dies horribly or acquires a coat of jade post-haste. In particularly Anvilicious cases, expect deployment of Diabolus Ex Machina to deal with them.

If the character remains triumphant and idealistic throughout, then it's a case of Good Is Not Dumb or The Pollyanna. May also be Stupid Good.

While messiahs are frequent victims of wide-eyed idealism, their suffering or sacrifice can encourage them to become full-blown Messianic Archetypes and inspire others in the setting to lighten up and thereby change the setting, unless they're a different kind of messiah, in which case the setting is only cemented.

When The Hero appeals to a group of people, often Least Is First falls under this.

Compare The Pollyanna, the Love Freak, The Ingenue, and Silly Rabbit, Idealism Is for Kids Contrast the Grumpy Bear, the cynic in an idealistic setting. See Turn the Other Cheek and The Farmer and the Viper.

Anime & Manga
"Havoc: He's stupid! How can such a naive thing keep climbing up in this country? Hawkeye: I think it's good that there are idiots like that, once in a while."
 * Goku of Dragon Ball is this full throttle. Throughout the series he is constantly offering his opponents a chance to change and be good people, even after they kill his friends he still has hope for them. He is overwhelmingly optimistic and nice to every person he meets. This will not, however, stop him from fighting to protect the people he loves.
 * Kenshiro from Fist of the North Star is an idealistic lives in a Crapsack World where people daily dies and kills over a scrap of food or a sip of water. Still he believes it is easy being despicable in that age, but it takes a true HERO keep your humanity and keep being a good person when everything and everyone around seems suggestng you otherwise. In the first chapter, Bat asks him bluntly how he has survived so far if he would not even try break himself out of jail because it could get a little girl in trouble. Not long after Bat finds out Kenshiro is idealistic because he can afford it. Behaving like scum and harming helpless people in front of him is a very, very bad idea. Like in "he WILL disintegrate you" bad idea.
 * Rurouni Kenshin Himura is a good example of this Trope. Some might consider him Incorruptible Pure Pureness, but old habits die hard...
 * Except his intro speech at the end of the first chapter goes, "no, swordsmanship is an art of killing. Kaoru-dono believes a sweet, naive lie. But if this one had a wish...it would be that her sweet lie would become the truth of this world." Kenshin's Walking the Earth with Obfuscating Stupidity routine involves some serious ideals, but despite avoiding his battle expression most of the time he's not too wide-eyed. He's got the world-weary thing going, but values Kaoru as a Wide-Eyed Idealist.
 * Some of the stupidity probably isn't fake. The line is impossible to find, as is common with Crouching Moron, Hidden Badass types.
 * His backstory involves a bit of this, despite all his childhood trauma—it caused him to wind up a sworn assassin in a civil war.
 * America is pegged as one of these by Fanon.
 * Though, considering his nature, he could very well be one of these in Canon.
 * Now and Then Here and There is based around this trope.
 * Judai of Yu-Gi-Oh! GX was once an Idiot Hero Ace who believed life was one big game and the only thing worth caring about was having fun. His journey of deconstructing The Ace is not a pleasant one.
 * Touta Matsuda from Death Note. Deconstructed with Light: it's pointed out that he is "quite the positive thinker" and ironically it's his idealism that drives him to commit his atrocities in order to "make the world a better place."
 * Kanzaki Nao in Liar Game. Almost every chapter. You'd think that one of these days she'd learn...
 * Except you know, she's usually proven right by the end.
 * Ichiro Yamada from the manga Freesia. He very much initially thinks that he can help the country by punishing ex-convicts and such, until he realizes quickly that the Vengeance Proxy Enforcer firm that he works for is nothing more than a group of contract killers for people who have massive grudges.
 * Both Suzaku Kururugi and Princess Euphemia Li Britannia from Code Geass genuinely believe they'll be able to reform the shockingly racist Britannian Empire and be facilitators for the peaceful integration of the Japanese people into the empire's fold. Cue Diabolus Ex Machina on a national scale.
 * This is subverted in the second season, where Suzaku forms a reasonable, if rather myopic, plan to free Japan (the rest of the world isn't his concern) and begins suffering from a bad case of Motive Decay until he realizes his ideals are nothing but smoke.
 * This is spoofed in official side comics, where Suzaku and Euphy are portrayed as so blindingly naive that they still believe in the Delivery Stork and Cabbage Patch Babies, while Lelouch looks on in stunned disbelief.
 * This trope is lampshaded artistically with Shirley, who has literally the largest eyes in the whole cast, with Euphemia just in second place.
 * In the manga version of Fullmetal Alchemist Scar's brother and the Rockbell family are wide-eyed idealists who believe in the basic good nature of man. The Rockbells leave their practice so they can heal the Ishvalans being massacred by the Amestris army, and Scar's brother wants to learn alchemy so that he can better understand the bonds of humanity. During an attack Scar's family is killed, and Scar's brother tries to shield Scar,
 * Roy Mustang is the other side of the coin. His sometimes borderline dumb faith in human nature helps him sometimes (when he took for granted ) and other times dooms him (when he believed  ). Still, his idealism is precisely what makes his subordinates so loyal to him.


 * The first anime, on the other hand, makes a point of contrasting Al's childlike optimism and naivete with Ed's growing cynicism and the horrible truths of the world aroung them.
 * Ai Tanabe, the newest member of Section 7 in Planetes. Her first name means "love," and it just picks up from there. She's taken to task for it countless times by fellow Section 7 crewman Hachimaki and Claire, Hachi's former Love Interest, the latter of which causes her to doubt her own ideals. And yet, although she's set up for a particularly cruel, which she could avoid by betraying her convictions, she stands by them  . Given the nature of the series,
 * Yuna Kagurazaka is one of the rare examples of this trope not to suffer either of the standard fates.
 * This is what makes Alice L. Malvin of Pumpkin Scissors stand out from many of the other nobles of the setting. She firmly believes in her cause to "eradicate evil" and that others will push for it too. This is what got Machis and Oland to join in the first place.
 * Albert from Gankutsuou, along with having Horrible Judge of Character. He is undoubtedly the most naive and idealistic of all the characters in that series. He truly believed for a long time that his friends' (and his own) families were perfectly rosy, and that the Count is a wonderful person. (He was very wrong, by the way - they were all insanely messed up.) Not to mention how he manages to go on about "true love". However, despite all hardships he goes through, Albert ends up taking the route A and becomes a better person who.
 * Negi of Mahou Sensei Negima starts out as one of these, but he eventually starts to realize that good and bad aren't quite as clear cut as he thought they were. Evangeline actually deliberately discourages his idealism (despite the fact that she's a Noble Demon who's constantly sliding towards Anti-Villain territory). Negi eventually admits that he can't always be the good guy, although he still tries to go with most "good" option available
 * Subverted in Baccano!!, specifically in Druge & the Dominoes: turns out that even the widest-eyed of wide-eyed idealists can be provoked into trying to blow your head off if you push the right buttons.
 * Tenma and Nina from Monster, despite being frequently subjected to horrific trauma. The fact that Tenma in particular absolutely refuses to become cynical about the human race drops him straight into Badass Pacifist territory.
 * Arguably, Éclair from Kiddy Grade, who, despite having dealt with the dreadful realities of GOTT and galatic politics for many, many years, has somehow avoided becoming a cynic, and actually keeps up her spirit to fight for her ideals. Granted, this may be due to two things: (1) she does use autohypnotic suggestions to, and (2) as a superhero, and with her partner, she does in fact have the ability to back up those ideals with with force.
 * Akari from Aria is a special case, in that she manages to stand out in a setting that is practically paradise incarnated.
 * Kafuka takes this trope and runs with it. Everything has a good side to her: a Trash Can is a 'Treasure Chest for the Homeless' and it only gets worse from there.
 * Trigun's Vash The Stampede is determined to be one. No matter what he sees, what humans or Knives or anybody do, to him or anyone. His traumas are simultaneously cases of Break the Cutie and Break the Badass, and are usually horrific. Worse in the manga, where he is clearly fighting to maintain his idealism over his own common sense and has a lot more bleak moments. The setting is also much darker, since the series went seinen after the Fifth Moon. But he always stands up again. Because he won't give up on humanity and by extension Rem.
 * And on himself. After all, if he gives up on people then what does he have to resist Knives' Hannibal Lectures with, and what have all these years meant? Therefore, Technical Pacifist willing to Turn the Other Cheek to a sometimes absurd degree.
 * The anime incident with Zazie mirrors Wolfwood's manga shooting of Rai-dei, in both cases to protect Vash. Vash is not appreciative, because he feels his sworn enemies should always have another chance to not-shoot him. Wolfwood, who's got a certain Knight in Sour Armor and Anti-Hero thing going on, thinks he's crazy but wishes he could believe the way Vash does.
 * Wolfwood's a priest. There are intentional religious themes here, although they are way vague and have a distinct lack of real theology.
 * Vash is helped by his own awesomeness; when Knives and his subordinated aren't involved he can usually pull a casualty-free resolution out of the worst situations imaginable. Sure, this has meant horrific scars all over his body, but it gives him all kinds of warm fuzzies and hope. He wants Wolfwood to see this. Wolfwood wants him to see that most people are only human and you can't save everybody all the time.
 * When Vash has a Heroic BSOD it's usually because of this getting challenged harder than usual. On some level he disbelieves a lot of it, and the fact that it's sheer will keeping him in line sometimes distinguishes him from the kind that are this because they don't know better. But somehow he keeps regaining Incorruptible Pure Pureness.
 * Know who's the Trigun poster child for this trope? Manga Knives. He was all "our hearts are the same as people's, I'm sure if we try we can understand one another," and actually cried when the first human they met besides Rem accepted them. Then he Went Mad From The Revelation that Humans Are Bastards, and resolved to Kill'Em All.
 * Meryl is a little naive but never an idealist. Millie is...strange. Maybe a wide-eyed idealist. Maybe just terminally clueless. Actually very sharp under it all, and very tough.
 * Anime Millie is Wolfwood's other foil, and they become a couple. One of Wolfwood's Character Development soliloquies involves the frustrated observation that Millie and Vash always "do everything I can't, like it's no big deal."
 * Sayaka Miki of Puella Magi Madoka Magica. Naturally, the series being what it is, it doesn't end well at all. Madoka is also one of these, although the story seems to jump through hoops to discourage it.
 * UC Gundam, have at least one pacifist who thinks they could stop the fighting, usually they are proven wrong and lives to watch the ramifications of their actions.
 * The titular character of Revolutionary Girl Utena, which, for some, can be infuriating when you realize that she refuses to see the emotional hardships that her peers go through (Juri's conflict over Shiori and her sexuality in general come to mind; Utena brushes it off and tells her to stop acting cold). Miki is this to a lesser extent, in regards to his sister Kozue, but it may be more that he's a genuine Nice Guy more than anything else.
 * The anime and manga incarnations of Princess Amelia of Slayers, both genuinely and to a comedic extent. She does have a blind eye towards the more wicked intentions of certain foes, especially the Monster race, but this is more of an ideology taught to her than anything else because of her violent family history. In the novels, where she's more mature, she's still optimistic, but her idealism falls more into Stepford Smiler territory.
 * The anime-exclusive character Filia, the Golden Dragon, is this combined with Holier Than Thou taken to aggravating levels. It doesn't help that she was sheltered for most of her life, but even after she learning the Awful Truth, during the last battle she believes that the Big Bad isn't beyond salvation (it's established clearly that he is at that point) and doesn't want to destroy him, even as he's consuming the world at that moment...
 * The neo-nazi band in Black Lagoon. Having no real experience with the way the criminal underworld works they're sent on a fixed race to "test their ability" against the protagonists, where they overspend resources, repeatedly underestimate the crew of the Lagoon, refuse to see facts, and waste time making dramatic and hammy proclamations about their heroic destiny as champions of the white race. Revy and Dutch kill all of them, and their would-be patron abandons them the moment it's obvious to him they've failed (though not before admitting to the leader that he set them up in the first place).
 * Rock also struggles with this in earlier arcs: His attempts to understand Revy makes her angry at him, trying to 'save' Gretel failed utterly, and his attempt towards Yukiko backfires completely. It isn't until "Le Baile de la Muerte" he starts to understand that if he wants to save people he'll have to become a cynical rotten power-player like Chang and Balalaika.

Comic Books

 * Steve in Gilbert Hernandez's "Love and Rockets X" story within Love and Rockets.
 * Gilly the Perky Goth from Dork Tower.
 * Tomcat in the Jedi vs. Sith. He believes everything he hears in the songs and stories that claim the Jedi are invincible heroes.

Fanfic

 * Blaine in Hunting the Unicorn to Fridge Horror inducing extents. He would help anyone who asked without question, which puts his Chronic Hero Syndrome in a completely different light. Greg has a point when he tells Blaine how lucky he is to have met Kurt, and that "all Kurt did was fall in love with him."
 * Saori Tagawa from The Ikaris is a marriage counsellor boasts she has NEVER failed on saving a marriage. She also has a very idealistic outlook about love and marriage. Attempts to talk her out of it are met with a Shut UP, Hannibal sharp retort.

Film

 * Will Proudfoot in Son of Rambow in spite of having lost his father and being raised in a repressively conservative religious household.
 * Alice, the innocent younger sister from Last of the Mohicans.
 * In Mr. Smith Goes to Washington, all Mr. Smith wants is a Boy Scout camp and nature preserve on a piece of land. Too bad the rest of the Senate is against him.
 * Danny of Cats Don't Dance.
 * Amy Adams's characters in Enchanted and Doubt.
 * While Charles Xavier in X-Men: First Class isn't exactly naive, he still has an extremely idealistic attitude towards Mutant/Human relations. Even when the humans turn on the X-Men in fear, he still continues to beieve that the mutants should try to be the better men, in the hope that they will someday be accepted.
 * Otto from One, Two, Three about Communism. He even thinks it's a capitalist lie that Siberia is cold, and is happy that the Communists assigned them "a magnificent apartment, just a short walk from the bathroom!"

Literature
""O sage Pangloss," cried Candide, "what a strange genealogy is this! Is not the devil the root of it?" "Not at all," replied the great man, "it was a thing unavoidable, a necessary ingredient in the best of worlds; for if Columbus had not caught in an island in America this disease, which contaminates the source of generation, and frequently impedes propagation itself, and is evidently opposed to the great end of nature, we should have had neither chocolate nor cochineal.""
 * Sansa Stark from A Song of Ice and Fire, who bases her whole life around singers' tales, is a perfect little lady, gentle and trusting.  And then MUCH misfortune followed.
 * Dangerous Beans in the Discworld book The Amazing Maurice and His Educated Rodents, who finds his dreams of a rat utopia all but dashed, and learns that on Discworld, you have to Earn Your Happy Ending.
 * Subverted by Carrot Ironfoundersson. He starts out as a wide-eyed idealist... Except that for some reason, his idealism somehow works. He can talk anyone into behaving like a friendly, reasonable person. If any other character tried it, they'd be dead.
 * It works because he's big, strong, usually accompanied by city watchmen (including a troll and later ) and, most important of all, is fairly intelligent. Carrot is an actual idealist, rather than just naive like most of the examples here; he knows full well that Humans Are Bastards and simply refuses to be one himself.
 * True but the world does tend to warp itself around him. After all he may or may not be the heir to the throne of Ankh Morpork and in a world chock full of narrativium, how can things not go his way.
 * Well almost any other character. In The Colour of Magic and The Light Fantastic, Twoflower, if anything, has an even more rose tinted view of the world, to the endless irritation of his traveling companion Rincewind - and likewise comes to no harm. Admittedly, this is probably because he travels with a Cosmic Plaything, so all of the trouble they run into goes goes after Rincewind rather than him.
 * Moomin- 'all I want is to grow potatoes and live in peace'-troll of The Moomins
 * Jane Bennet of Jane Austen's Pride and Prejudice. Her younger, more cynical sister, Elizabeth, is convinced that Jane's new friend, Caroline Bingley, deliberately sabotaged her romance with Caroline's brother in order to hook him up with his best friend's sister—all to increase her own chance of getting hitched to said best friend. Jane remains convinced that Caroline is her affectionate friend and would never do anything to hurt anyone, and more importantly, never do anything less than beneficial to her brother's happiness. Obviously he must prefer Georgiana... It takes a surprise face-to-face meeting with Caroline for Jane to admit Elizabeth was right about her, but she displays the same naivete and belief in love and the innate goodness of man when Wickham seduces their youngest sister, Lydia—despite Jane and Elizabeth knowing that he's tried the same technique on at least two other girls.
 * Dorden, The Medic of Warhammer 40000: Gaunt's Ghosts has aspects of this, in trying to adhere to Thou Shalt Not Kill and preventing Gaunt from carrying out necessary Shoot the Dog despite their World Half Empty.
 * Voltaire's Candide. Among many, many other examples in the book is Dr. Pangloss's thoughts on having caught syphilis, and having had an eye and an ear removed as part of the treatment:

"Thrawn: There are all too few idealists in this universe, Car'das. Too few people who strive always to see only the good in others. I wouldn't want to be responsible for crushing even one of them. Car'das: And besides, you rather liked all that unquestioning adulation coming your way? Thrawn: All beings appreciate such admiration."
 * The main character of Invisible Man is both this and a Love Freak, albeit with (absolutely desperate) followers. Since he's also a Horrible Judge of Character, he runs into a few problems . ..
 * Colin Creevey in Harry Potter falls under this with his cheerful, naive, and innocent loyalty to Harry at all costs.
 * Hermione also has her moments, with her working for House Elf rights even though they have Happiness in Slavery, much to the amusement of others who know better.
 * In Outbound Flight, the smuggler Maris Ferasi fit this trope pretty well. She had the utmost trust in and adoration for the Chiss commander Thrawn. Unusually, she wasn't disillusioned within the book - Thrawn lied about what he had done to resolve an extraordinarily prickly conflict, letting her leave without knowing just how much of a Downer Ending the whole issue became. Why?

""Alone of us all, Rinaldo has no personal ambition. He sees in Conan a red-handed, rough-footed barbarian who came out of the north to plunder a civilized land. He idealizes the king whom Conan killed to get the crown, remembering only that he occasionally patronized the arts, and forgetting the evils of his reign, and he is making the people forget. Already they openly sing The Lament for the King'' in which Rinaldo lauds the sainted villain and denounces Conan as 'that black-hearted savage from the abyss.' Conan laughs, but the people snarl." "Why does he hate Conan?" "Poets always hate those in power. To them perfection is always just behind the last corner, or beyond the next. They escape the present in dreams of the past and future. Rinaldo is a flaming torch of idealism, rising, as he thinks, to overthrow a tyrant and liberate the people."''"
 * Drizzt Do'Urden in Homeland; he gets mildly bitter during the later portion of the novel when he finds out that his favorite mentor Zak kills clerics by the dozens,.
 * The young baby-faced soldier boy in All Quiet on the Western Front definitely qualifies.
 * Don Quixote severely deconstructs this trope: In the first part, Don Quixote cares more for fulfilling his fantasies than for anyone else. He confides that the farmer Haduldo will stop floggin the boy Andrés and that the Galley slaves he liberates will be grateful enough to make him a favor. (They´re not). His actions make him the original Lord Error-Prone. In the second part It Got Worse: Don Quixote really acts For Happiness and after some Massive Multiplayer Scam aventures that convince him he is a real Knight Errant he must face the sad fact that he has not helped anyone and therefore, all those Chivalric Romance tropes were Blatant Lies. This is so heartbreaking that he becomes Bored with Insanity and dies. Being called "Quixotic" is not always a good thing.
 * from Warbreaker - his entire experience of life outside his palace consists of having been read a book of fairy tales by his mother as a child. Semi-subverted in that while he does develop a more realistic view of the world, he never loses his almost childlike sense of straightforward goodness.
 * I'd say Toglio in Norman Mailer's The Naked and the Dead. Always thinking to himself about how he and his squad are "The good ol' boys", hard-working and patriotic. Then, of course, he gets his leg shot up to hell and sent home.
 * Cosima from Comrade Death. She flat out refuses to see Sarek for what he really is.
 * Rinaldo in Robert E. Howard's Conan the Barbarian story "The Phoenix on the Sword," one of the conspirators of Ascalante's plot to overthrow Conan.


 * Zoe in Saving Zoe, and this trait is why her sister Echo believes she was killed
 * Isherwood Williams in Earth Abides, although he's not a complete naif.
 * Twenty Thousand Leagues Under the Sea: The Professor Aronnax must be constantly reminded that other people is not as good as himself. He really doesn’t want to believe that Nemo is doing something sinister, and Ned Land must remind him that the war ship that is shooting the Nautilus is doing it on purpose.
 * Tyentyetnikov starts as this in Dead Souls, tries to improve the lot of his serfs, with at best mixed results, and becomes apathetic in the end.

Live-Action TV

 * Hiro of Heroes is a careful treatment and examination of this trope.
 * Dr. Molly Clock in Scrubs. Partially subverted, however, in that her incorrigible optimism is undaunted in the face of the naked cynicism of Dr. Cox and Dr. Kelso, and even allows her to triumph against them.
 * J.D. himself might fit too, at least at the beginning.
 * And then there's the one-episode character from season one, who is eternally optimistic about the chances of a little boy in his care, until finally he suffers a Heroic BSOD as he realizes nothing he's tried is working and the kid is going to die.
 * Sam Seaborn in The West Wing. Often, he creates idealistic scenarios and goals that sound wonderful, but when he presents them to Leo or the President, they are shot down because of being impractical, a waste of time, or just plain dangerous. He also is very trusting and naive, which gets him into trouble on a frequent basis. Often, as in the case of a public education plan he developed that would have been revolutionary, he completely forgets to factor in a budget, accidentally assuming that there are no limitations. Ironically, this makes utter sense, as this seems to be the most glaring problem with entire American Dream.
 * New correspondent Kristin Schaal is currently playing this (along with The Woobie) on The Daily Show - it remains to be seen how long it will last, as she is cruelly disillusioned in just about every appearance.
 * Lieutenant George in Blackadder Goes Forth, despite having spent three years in the trenches of World War I, is still mindlessly optimistic about giving the Germans a good bashing, and readily believes all war propaganda to be true. The grim reality of his situation (in particular, the event of 'going over the top' he's been looking forward to for all the series) dawns on him when he realises that he's the only one of his class group left, all the rest having been killed.
 * His response to realizing all his friends are dead is "Well, I guess I'm the only one left... oh.... I mean, if it wasn't for the excitement of going over the top tomorrow, I might be a bit down!"
 * Subverted when he says to Blackadder: "Captain, I'm... scared." Up until that point, I wasn't sure whether or not this was intended to be more of the show's black humor, or if it was actually supposed to be horrifying. That line cleared it right up. Then, It Got Worse.
 * Edith Keeler in The City on the Edge of Forever..
 * Naive, gentle Tora Ziyal, despite growing up as a prisoner of the Breen, despite being rejected by Bajorans and Cardassians for her hybrid status, still remains trusting and hopeful that she can somehow help, with her art that resembles that of both cultures, in proving that the groups aren't so different after all. She knows her father, Dukat's past, but loves him anyway, sincerely believing he's changed, and keeps right on forgiving him.
 * David Shephard and Michelle Benjamin both fit this trope to a T in Kings although David seems to be growing out of it.
 * Shinji in Kamen Rider Ryuki, caught in a fight for a single wish, Shinji fights to try and stop this but learn he could not...
 * Annie in Community. She even thinks her nickname is "Irony-free Annie".

Music

 * Billy Joel's song "Pressure" is about a Wide-Eyed Idealist and how unrealistic his hopes and expectations are.

Musical

 * Anthony Hope in Sweeney Todd: The Demon Barber of Fleet Street is as idealistic as Sweeney is cynical. And then he gets bashed (literally, in some cases) down by Judge Turpin and the Beadle. And he is still idealistic, even though everyone - even his er, bride, Johanna, tumbles down the Sliding Scale of Idealism Versus Cynicism. And it can be viewed as all HIS fault.
 * It should be noted, though, that Anthony Hope is one of the few characters still alive at the end.

Newspaper Comics

 * Ratbert in Dilbert is (or was) pretty much the only idealistic character in the Crapsack World the strip takes in. Considering the strip's message that "cynicism equals intelligence", it comes off as no surprise that he's portrayed as stupid.
 * Pig, the title character of Pearls Before Swine, has a very idealistic outlook on life. This makes him a perfect Foil for his Nietzsche Wannabe roommate Rat.

Tabletop Games
""For example, a new angel performing a mission in modern-day America knows that interstate buses are a method of transportation, and that they begin and end their trips in metropolitan bus stations. ... Bur the angel is unlikely to realize that it's a bad idea to spend the night in a bus station, or that the nice man who offers to watch your luggage while you get a drink won't be there when you get back (and neither will your luggage)." -- APG, pg. 80"
 * The Tau in Warhammer 40000 started out pretty close, before the inevitable grimmification. They still qualify in that galaxy, even though in any other they'd be the bad guys the heroes have to stop at all costs.
 * Also the Chaos God Nurgle, in a very weird way.
 * In the backstory of the old Battletech world, the last First Lord of the Star League, Richard Cameron was orphaned as a boy, and grew up with idealistic, Arthurian vision of his supposed role as head of the multi-kingdomed, federal empire. Since politics in the Battletech universe are much more realistic than that, he was the worst possible choice for the critical throne at the worst possible time, and catastrophe followed.
 * Not helped by the fact that an Evil Chancellor, who would later go on to kill Richard and bring the Star League to ruin, was warping his mind and constantly clouding his judgment towards said idealism.
 * According to the Angelic Player's Guide of In Nomine, angels that are brand new to Earth sometimes have this tendency. After all, they've spent their entire life in an environment where everyone really is out for the best.

Videogames

 * Tahlkora from Guild Wars: Nightfall. "I signed on for the heroic songs and the praise. I did not sign on for the blood-sucking bugs."
 * Will / Ed from Advance Wars: Days of Ruin / Dark Conflict. His idealism arguably pushes him dangerously close to being an Idiot Hero, as he is often wildly optimistic and consequently sometimes fails to look at situations properly. However, his will and sheer determination in even the worst of situations often leads to at least one crowning moment of heartwarming. Case in point - mission 16, which starts off with desperate music playing pushing ever closer to the Despair Event Horizon, when suddenly Will/Ed decides he's going to fight, and the music changes from desperate to sheer awesome.
 * Flonne in Disgaea falls under this trope. She never ceases to be an overoptimistic idealist who believes that demons can love, and that Seraph Lamington is a good guy.
 * In the best ending.
 * Her Expy, Marona definitely fits into this (despite her situation).
 * BioWare usually includes at least one in the party, who is usually also young and female.
 * Aerie from the Baldur's Gate series, as becomes apparent if you put her in a party with Keldorn, Haer'Dalis or Jaheira.
 * Mission Vao from Knights of the Old Republic. Despite being a product of one of the galaxy's worst WretchedHives, she is a cheerful girl who's higher on the Karma Meter than the party's Jedi and is the first to support the Player Character after the Tomato Surprise hits.
 * Tali and Liara in Mass Effect, less so in the sequel.
 * Leliana in Dragon Age, though how she keeps that perspective in that Crapsack World is beyond us.
 * She's no idealist; she was a, after all. Hers is more an example of Becoming the Mask and Knight in Sour Armor.
 * Fenthick in Neverwinter Nights, so much that he cannot comprehend evil. Linu is a lesser example.
 * Dawn Star in Jade Empire.
 * PJ in Ace Combat Zero. Given Ace Combat tries to use "War Is Hell" as An Aesop, and he mentions his girlfriend back at the base...
 * Luisa Fortuna in Red Dead Redemption is an exceedingly idealistic individual in the Crapsack World. She genuinely believes in rebel leader Abraham Reyes, who John quickly learns is a Glory Hound with a penchant for Meaningless Meaningful Words and chastises John for working with Allende when he constantly makes it clear that he's Not in This For Your Revolution.
 * Brother-Sergeant Thaddeus in Dawn of War II, with most of his older and wiser fellow sergeants pointing out his relative naivete at several points. In the Expansion Pack Chaos Rising,
 * In Deus Ex Human Revolution, David Sarif is this to an extent. In a world of high tech cybernetics, ruthless conspiracy, corporate warfare, And Bad Weather—signs that would warn a Genre Savvy individual that s/he's in a Cyberpunk setting, Sarif believes that the best thing to do with augmentation technology is to remove all restrictions on it, and that doing so will help the people of the world.
 * The Kingdom Hearts series plays with this trope, ultimately subverting it: Sora is so idealistic that villains often take advantage of his do-gooder tendencies and manipulate him in various ways. The villains all insist that the protagonists are Wide Eyed Idealists who should just give in and admit that the world is nothing but darkness at its heart. A notable example is in Kingdom Hearts: Chain of Memories, when Sora is manipulated into  Ultimately, his idealism and his bonds with friends protect him.

Visual Novels

 * Shirou Emiya of Fate/stay night, who wants to follow in his father's footsteps to become an "ally of justice" and enters the Holy Grail War to prevent civilian casualties and abuse of the Holy Grail. The end result depends somewhat on the route: in the first route,  in the second route, and  in the third. The latter ones are foreshadowed in "Fate" when he couldn't come up with a real answer about if what he was doing actually brought him happiness.

Webcomics

 * Seiko from Used Books is a great example. She is constantly standing up for people tho others deem as villains. She holds fast that people are basically good, even if they have done nothing but cause hardship. She also stops in the middle of a battle to bandage up an enemy someone on her own team just injured.
 * Lisa from Mechagical Girl Lisa A.N.T. is one of these... only thing is, not only she still firmly believes her life is a Magical Girl anime despite all she's been through, but she doesn't even cares about her robot outfit being actually a Humongous Mecha for ants.
 * Franchesca "Kid" Martines from Angels 2200 is a textbook example. Not surprisingly, she almost gets booted off the squad when she can't bring herself to fire on an enemy fighter knowing she'd be taking someone else's life.
 * Played with in Homestuck with John Egbert. He's a wildly idealistic kid playing a game that's already destroyed the Earth and rendering it more or less uninhabitable, and being constantly accosted by literal Trolls who continue to call out the fact that the kids fail to win the game and nothing they do will change that. This doesn't seem to deter John in the slightest.
 * In El Goonish Shive, Grace is this in all things including nudity, and so was  before

Web Originals

 * Himei of Sailor Nothing was once a Genre Savvy Ascended Fangirl of Magical Girl anime... starring in a Deconstruction of Magical Girl anime. She quickly learned (by the beginning of where the story picks up) that the job is not so much fun as it looks. Aki fills the role after Himei has become thoroughly jaded.
 * A toned-down version of Penny in Dr. Horrible's Sing-Along Blog. "...a generally nice person whose idealistic attempts at solving the problems of their world turn out to go horribly horribly awry..." Do I detect a bit of irony?
 * Emma Babineaux of the Battle Royale based RP Survival of the Fittest arguably fits this. After winning a fight against J.R. Rizzolo, instead of shooting him, she tries to convince him to stop killing and escape the island with her - this being after he attempted to murder her twice.
 * Chris Davidson from v4 may indeed be this as well.
 * One could easily make a case for Carol Burke as well, who seems to genuinely believe they are going to be rescued and the terrorists wouldn't get away with it a fourth time. To her, very few at her school would actually play, especially her friends. Heck, she trusts Reiko Ishida.
 * Orn "Dutchy" Ayers could also be interpreted as this. However, it's also a major reason why he's considered The Woobie; he's smart enough to know that although things should be good and he wants to do the right thing, things... aren't working out. As a result, he doesn't take things very well, and spends a good portion of his time on the island in a Heroic BSOD, wishing he could save all his friends.

Western Animation

 * Silverbolt of Beast Wars started out as a starry-eyed idealist. He was so thoroughly chivalrous that he refused to hit or fire upon a female (Blackarachnia) even if his own life, or the lives of his comrades, depended on it. His naivete took its toll in the three-part second season finale where he refused direct orders from Optimus to capture Blackarachnia, instead going after her to help her dig up the Ark. This enabled Megatron to make it to the Ark easier and gain the access codes from Blackarachnia after threatening Silverbolt's life. Then Megatron went into the Ark and fired a fatal blast into the still dormant Optimus Prime's head, triggering a cataclysmic time storm that nearly destroyed all the Maximals and wiped out time and space. All thanks to Silverbolt's refusal to capture Blackarachnia. Later on, of course, everything gets cleaned up but Silverbolt's actions nearly led to the destruction of time and space due to his wide-optical idealism. In Beast Machines, this trope becomes subverted as Silverbolt is transformed into the villainous Jetstorm. Blackarachnia does bring him back but once Silverbolt returns, he no longer has the rosy outlook on life that he used to, becoming a bitter Anti-Hero for the remainder of the series.
 * It should be noted that despite leading Megatron to the Ark the first time, his continued pursuit of Blackaracnia kept her on the Maximal side all through season 3 despite some close calls regarding her Chaotic Neutral yearnings. In fact, it's only because of his devotion that ultimately she becomes a real Maximal. This ironically is the only thing that saves the future yet again when she's the last maximal to survive a mental takeover of Optimus Primal, and thus she's able to save the ark from self destruction.
 * Wally from the Where's Wally cartoon series fits this trope to a T but manages to avoid the horrible death part. He's too cheery for his own good and his dog Woof has more common sense than he does yet he always escapes unscathed from his dangerous journeys.
 * The Fantastic Racism of Manhattan is particularly painful for Angela of Gargoyles, who was raised on Avalon where humans and gargoyles live in harmony. She also hopes more than is wise or reasonable that her mother Demona can change or be redeemed.
 * Subverted with Yoink from the "Yoink Of The Yukon" short on What a Cartoon Show. Oddly enough, he survives and his cynical partner gets to be The Chew Toy.
 * Felicity in Felidae who seems to believe good in everyone despite being blind. Unfortunately...
 * Jimmy Two-Shoes manages to be one of these in Miseryville. While he suffers plenty of Amusing Injuries, he usually comes out on top, with Lucius really suffering.
 * Zeta from The Zeta Project pretty much is this trope, naive and kind, always taking people at their word, a terrible of judge of character who thinks the best of everyone and generally easily manipulated. It's due to being so young and having no knowledge of the world beforehand, and to be fair, his friends do try to help him get better about this.
 * This trope + Well-Intentioned Extremist + Idiot Hero + Perky Goth with a side order of Dem Bones and Bad Santa gives us Jack Skellington.
 * Aang started off this way. But being shouldered with the weight of the Avatar Spirit, his entire people dying, Appa's kidnapping and the horrors of war quickly got rid of it.
 * Zuko also started out this way. Then his father burned his face off and kicked him out of the country as punishment for his idealism.
 * In Transformers Prime, Optimus when he was Orion Pax as Megatron's protege in the Cybertron civil rights movement. He ended up endearing himself to the general public compared to his mentor's more ruthless methods.
