"Resentment is like taking poison and waiting for the other person to die."
— Malachy McCourt
"His resentment boiled up behind his eyes like sinus pain. All this bloody hero worship, or whatever it was. All for Naismith. For Naismith, and not for me... never for me..."
Seto Kaiba in Yu-Gi-Oh!. Aside from disliking Yugi for having dethroned him as dueling king, he also likely resents the idea that Yugi (or rather Yami Yugi) wins against opponents Because Destiny Says So, while Kaiba's own hard work against said opponents isn't worth squat.
Upon accepting that Yami Yugi is real, Kaiba is entirely resentful of Yugi for this. Until he's watching the end of series duel between the Pharaoh (Yami) and little Yugi. And watches Yugi be a genius. By way of defeating the Three Egyptian God Cards through Rules Lawyering. Seriously, who thought that making Slifer automatically attack every new monster was A GOOD IDEA?!
Kaiba himself attracts one resenter after another in anime Filler Arcs. There's foster brother Noah, who hates him for stealing what Noah feels was rightfully his, and the Big 5 who resent the way Kaiba discarded them after all the work they did helping seize control of the company. Finally there's Kaiba's Evil Counterpart, Siegfried von Schroeder, who resents the fact that KaibaCorp was able to sign a deal with Maximillion Pegasus and Industrial Illusions first, thusly putting Siegfried out of business.
Dragon Ball Z's Vegeta, who seems to be the inspiration for Kaiba. "I'm a prince, you're the son of a lowly fighter!"
Vegeta's resentment is born of his pure, unadulterated arrogance. Sorry, "pride". But then, if you were constantly being upstaged by Goku then you might be a little resentful too. Truly, Krillin is a saint for his patience.
Mello in Death Note is this to Near, since Near continually edged ahead of him at their mutual School For Scheming. His overriding motivation throughout is to prove himself superior to Near.
Ranban from Space Pirate Mito's villainous motivation comes from being imprisoned because his body never settled on a gender, which drove him insane enough to get revenge by blowing up the entire royal family (which he was part of)'s planet. Only Mito escaped, and he continued to pursue her, mostly because he resented the fact that she could rule the galaxy while he was denied this right, despite the fact they were practically twins, except for the gender thing.
Katsuhiko Jinnai from El-Hazard is constantly number 2 in everything, right after Makoto Mizuhara (he gets lower grades, is second in races during gym, and is right behind him in lunch line, presumably among others). So Jinnai declares them lifelong rivals, much to Makoto's confusion, and joins the villains in the other world.
Actually, in the original OAV series at least, Jinnai was pretty much a villain-in-the-making to begin with. He truly hated Makoto for always managing to best him, but he signed up with Queen Diva and the Bugrom because he liked the sound of their mission to conquer the world, not because of his hate for Makoto.
And in the TV series Makoto is far more laid back and doesn't really participate in anything other than his science experiments, making Jinnai's jealousy all the more irrational, and hilarious.
In Naruto...well Naruto himself fits this trope actually, at least for the first half of the first series. He spent the early part of the series jealous of the attention and praise Sasuke received.
After which it reversed and he calmed down and viewed him as an equal, while Sasuke started to freak because Naruto had become his equal, or better. Apparently he became the resenter because the Superpower Lotterywasn't enough anymore.
Neji resented the Main Branch Hyuuga for the freedom they stole from him and the death of his father. He especially resented Hinata for being weaker than him yet holding a higher position within the clan.
Danzo was this to Sarutobi, the Third Hokage, since he always resented how the latter would give without hesitation his life for his comrades, and because of this he becomes Hokage.
Madara was this to Hashirama Senju, also known as the 1st Hokage.
Sugimoto in The Twelve Kingdoms, who as the series continues starts to take her belief that The Chosen One was chosen incorrectly to annoying heights.
In the Scramble For The Throne arc of Kinnikuman, Super Phoenix is bitter that a buffoon like Suguru has so much wealth and fame, while he grew up in poverty and obscurity.
Ultra Magnus in Transformers Robots In Disguise, who feels that as the strongest warrior on Cybertron, he was more deserving of the Matrix than Optimus Prime.
Ryoga of Ranma ˝ blaims Ranma for almost everything bad about his life. The main reasons why he's resentful are: (1) Ranma always beats him in their fights. Always. Even if Ranma loses, he always challenges Ryoga to a rematch and beats him in the end. (2) Ranma's curse turns him into a hotgirl, while Ryoga gets turned into a little, black piglet, all because of an accident involving the two of them. (3) Ranma's engaged to Akane and gets all her attention, while Ryoga is stuck in the friend zone.
Future GPX Cyber Formula has Naoki Shinjyo and Karl Lichter von Randoll. The former becomes extremely resentful of Hayato (truthfully, he's more resentful of himself), and the latter not only is resentful of Hayato's later success, but also of his relationship with Asuka. In 11, he resents Schumacher for what he thinks is messing up with his pace. Both of them get over it as the series progresses.
In the original Mobile Suit Gundam Kai Shiden and especially Hayato Kobayashi resent Amuro Ray for his talent and the fact that he is key to the survival of the crew; from their perspective he is given far too many privileges because of this. It gets to the point where they desert the ship in a rage because Amuro wasn't executed for his own previous desertion of the ship. Kai gets over it.
In Rurouni Kenshin, Yumi Komagata is revealed to have been this toward the fighters in the JuponGatana. Because Makoto Shishio, her lover and their employer, always respected strength and good fighting ability, their skills made her feel useless by comparison. This prompts her self-sacrifice during Shishio's fight with Kenshin, in an effort to be somehow useful to him in a battle.
Envy is this in Fullmetal Alchemist. It resents the entire human race for their ability to live full lives despite their limitations, something that it is literally incapable of doing.
In the 2003 anime version, however, he resents the Elric brothers (and anyone else with a functional family) on account of his own Parental Abandonment.
Between insane Casca and her caretaker Farnese, Farnese feels resentment toward Casca because she often causes Guts trouble out of her current fear toward him. Despite this, Guts still goes out of his way for her and is, in fact, still deeply in love with Casca and is striving to find a cure for her insanity. However, Farnese has feelings for Guts, and although she knows that it is highly unlikely that he will ever reciprocate her affection, she at least wants his merit in the group as a witch in training. Guts does see Farnese as person of worth to his group... but beyond that, he doesn't see her as anymore than Casca's caregiver.
Young Sonia resents Princess Charlotte and the relationship that she has with Griffith as his fiance (and his Meal Ticket), seeing her as nothing more than a useless duck who has no real use beyond being the key to the throne of Midland, while Sonia sees herself as being a much more useful kite since she is gifted with clairvoyance and knows that Griffith is beyond this world.
In 3-gatsu no Lion, Kyoko resents Rei for being the best in shogi (and by extension, gaining the attention of their father), and that resentment is shown through her attempts to lead him into failure, even when she's being fairly cordial to him otherwise.
The Human Alien commander in The Legend of Black Heaven is this in spades. He's a highly-trained, highly-decorated military veteran commanding an armada of hyperadvanced spacecrafts... and yet, he's completely dependent on a fleet-destroying Wave Motion Gun driven by The Power of Rock... specifically, the rock stylins' of one middle-aged ex-rockstar from an Insignificant Little Blue Planet. His resentment occasionally boils over, prompting him to challenge the Horde of Alien Locusts in a conventional engagement - which, inevitably, leads to heavy losses, near-defeat, and a mad scramble to invite The Chosen One back on the ship to fire up the Wave Motion Gun. His growing suspicion that his fiancee (whom he's too busy commanding the fleet to pay much attention to) may be getting a bit TOO close to the 'hero' she's supposed to be managing, doesn't make things better...
Comic Books
Some continuities depict this as a primary motivation for Lex Luthor's hatred of Superman (apart from the whole "thwarting of his evil" thing): that this otherworldy alien creature, in possession of massive power, but without the intelligence to use it correctly, is able to lord over humanity as the Beloved Favorite Son of Metropolis, rendering all the accomplishments of self-made Badass Normals like himself moot. Without Superman, Lex would rule the world, and he constantly blames Superman for "forcing" Lex to spend his time thinking up ways to kill Supes rather than stopping global warming or curing cancer. (Though as Superman has pointed out, if Lex were interested in saving the world, he would have done it already.)
One strip based in the DCAU demonstrates his resentment perfectly, with a young Lex Luthor planning the future center of his business empire and declaring it will be the tallest building in Metropolis and everyone will look up to him. And then shows the present of him standing in the tallest building in Metropolis - looking at Superman flying overhead.
Darius Dax, the Lex Luthor analogue in Supreme, makes the resentment an explicit part of his origin: a child genius who feels that he is constantly overlooked because of this hick that stumbled over a power-giving meteor one day. This comes directly from Silver Age Lex Luthor's resentment of Superboy. Child genius overlooked by a super-powered hick. In his zeal to outdo Superboy, he created an accident and Superboy's attempt to fix it caused Lex Luthor to go bald.
Generations where Joel Kent, the son of Superman loses his powers in the womb, and grows up with a sister who didn't. They tried to keep it all from him to avert this but fellow resenter Lex Luthor told Joel and began manipulating his resentment from an early age for his own purposes. (Nevermind Lex was ultimately responsible for Joel's plight in the first place.)
In Action Comics #900, Lex Luthordiscovers Superman and Clark Kent are one and the same. This gives yet another reason to resent Superman: Lex had to grow up with an abusive drunkard for a father while Superman, an alien, grew up with loving parents.
Luthor: I was happy to be rid of what I had for a father! But you... You got them! You're not human! You don't deserve to be Clark Kent!
The Batman story The Long Halloween, portrays DA Harvey Dent's feelings toward Bruce Wayne after the latter is acquitted of murder as resentment: that someone as dedicated to doing justice and right as Harvey must see his family live on the edge of poverty, while the Rich Idiot with No Day Job can live a life of ease, buying anything, even a Not Guilty verdict.
Rayek in ElfQuest, in almost every flavor of the trope at some point in the story or another. Since the story unerringly paints the Wolfriders as heroes, Rayek's situation is drawn in a rather unsympathetic light no matter what it is.
Guy Gardner in Green Lantern, though perhaps this was justified, considering he only lost out because the other candidate was closer to the one handing out the Hero Ball. He does get over this though... eventually.
The initial antagonism between Spider-Man and the Human Torch was because they both resented one another. Peter was jealous of Johnny's fame and public status while Johnny was jealous of Peter's relationship with his Aunt May and his status as a Chick Magnet.
Veronica Cale. Veronica's hatred and jealousy of Wonder Woman was so powerful that she did everything she could to ruin her during Greg Rucka's run on the comic. She ran a smear campaign against Diana, helped turn an innocent acquaintance of Diana's into the next Silver Swan, and released Doctor Psycho in an attempt to turn a crowd of people against Diana. In 52 this trait was eventually dropped and she became a more typical Mad Scientist since working on the Horsemen of Apokolips project had driven her (more) insane.
Doctor Doom, for his Arch-Enemy Reed Richards of the Fantastic Four. The reasons for his blinding hatred of Reed are numerous, twisted, personal, and all-around complex deludedbatshit insane, but what has kept it running for two in-universe (and five real-life) decades is a constant dose of this trope. Reed has everything Doom doesn't quite have — a family, loyal friends, public acknowledgement, admiration from people who aren't brainwashed subjects of his own dictatorship, good looks (which Doom once had, and actually blames Richards for their destruction), acknowledgment as a hero, and most important of all, a handful more IQ points, which he has used to defeat Doom and foil his plans time and time again. In short, Doom cannot stand the fact that Reed is always just one teensy bit better than him at everything.
Prior to his Face Heel Turn, Hunter Zolomon appears to have been this toward Wally West, albeit low-key. To be more specific, Hunter disliked being stuck with a desk job at the Keystone City Police Department as opposed to being able to run around like Wally could (due to having a limp from a gunshot to the knee when he was in the FBI). He also believed strongly that tragedy makes better heroes, but that Wally failed to appreciate this view because unlike Barry Allen and Hunter himself, Wally had never known personal tragedy. Following his transformation into Zoom, he became determined that Wally should see things his way, even if it meant attempting to kill Wally's Love Interest in front of him.
There's also the earlier case of Barry's previously-unknown Evil Twin Malcolm Thawne, better known as the super-villain Cobalt Blue. Separated from his real family at birth to cover up the attending doctor's accidental killing of another couple's child on the same night, Malcolm grew up with the second couple, a pair of con artists who treated him horribly, the abuse exacerbated by their knowledge that he wasn't really theirs—something he wouldn't learn until years later. After finding out the truth of his parentage, Malcolm also learned that Barry was the Flash, and hated him both for having the good childhood Malcolm got cheated out of and for gaining powers Malcolm (believed he) should have rightfully received.
Fan Fiction
In the Jackie Chan Adventures fanfiction Queen Of All Oni, after her Face Heel Turn, this forms a huge part of Jade's villain persona: she resents her parents for always ignoring her and shipping her off to relatives she didn't even know she had; she resents Jackie for never giving her the gratitude and respect she thinks she deserves for saving both his life and the world on multiple occasions; she resents Uncle for picking Tohru (a practical stranger) over her (family) as his apprentice; and not only does she resent Tohru for being apprentice instead of her, she hates him for bringing her back down to normal last time she was the Queen.
This sets one of the plots in motion in the WWE story, A New Beginning, as Gail Kim performs a Face Heel Turn on the brand-new Women's Champion, Melina. Gail claims that she's worked hard over the years and has nothing to show for it, while Melina sat out almost a year with an injury and got a title shot almost immediately upon her return.
In the wrestling fic A Ring Of Their Own, Victoria is shown at times feeling this way about Trish Stratus, especially when Trish signs on with the FWF, the federation Victoria founded and became the first champion of.
Film
Rotti Largo from Repo! The Genetic Opera has a lot of this—first his love married someone else causing him to kill her, then his children grew up to be astoundingly psychotic failures, then he became terminally ill. Poor guy. It would make anyone turn into a bastard, though Rotti saves time by being one from the start.
Lt. Col. Tall from Terrence Malick's The Thin Red Line feels slighted due to having been passed for promotion. (Contrary to this, he displays no such characteristics in the novel the film is based on and enjoys a very successful career.)
The Godfather Part II: Fredo Corleone to his younger brother Michael, when Michael becomes the Don.
In Amadeus, Salieri is jealous of the vulgar Mozart's gifted talent with music.
Megamind. So much. The titular alien is this, with his rival, Metro Man (a more human-looking alien), being the object of his envy. To summarize: they arrived on Earth at the same time. Megamind was en route for a mansion, but Metro's shuttle knocked him off-course, bouncing Megs into a prison and landing "the good life" for himself instead. Years later, Metro was beloved by his shool while Megs was ostracized, leading Megs to become a supervillain since everyone hated him anyway.
He is also jealous that Metro Man always gets the girl. (After all, who would date a blue alien supervillain?) It's implied he had a thing for Roxanne even prior to the movie. And let's not even mention that thing with Bernard...
Then when Metro Man dies (fakes his death) and Megamind is challenged to be The Hero for once, and he ignores the call... yeah, major resentment there.
Loki in the new Thor movie combines this with being The Unfavorite to make his very own villainous motivation. Probably.
It carries over into The Avengers. Loki tries to enslave the entire earth just because Thor has grown fond of humans.
In What Ever Happened to Baby Jane?, the titular "Baby Jane" Hudson, a forgotten Former Child Star greatly resents her sister, Blanche because Blanche had a much more successful career than she did.
Robin Hood: Prince of Thieves: Will Scarlet is this toward Robin for most of the film, though we don't find out why until the last third of the movie. Will is Robin's half-brother and the illegitimate son of their father, who sent him and his mother away because the affair upset Robin. Will and his mother wound up living in poverty, while Robin remained with his family's wealth and legitimate status.
The major villains of the Iron Man films all hate and resent Tony Stark.
Live Action TV
Buffy the Vampire Slayer had Faith, whose Face Heel Turn came largely as a result of resenting that, although she was the Slayer, the Chosen One, Buffy had the family and friends she never had, the role of leader, and all the respect and credit Faith deserved.
And that whole, them wanting her to at least stand trial for what was an accidential murder that she had no way of ever being found innocent.
An accidental murder that, in a court of law, Buffy would have actually been held equally responsible, seeing as she's the one who slammed him down and held him for Faith to kill him.
Colonel John Casey made it clear from day one that he resented having to guard "that moron" Chuck. Strangely, he had a problem with is orders to kill Chuck upon completion of the Intersect. The series constantly played with the idea that he might Face Heel Turn. (He still might).
In Noah's Arc, this is a big part of Guy's motivation. He resents Alex for having a man like Trey and treating him the way that he does, so he goes out to get Trey for himself.
It is implied at this, along with Sibling Rivalry was what came between Shawn Farrell and his brother Danny in The 4400. To be fair to Danny, Shawn kind of stole his girlfriend and their mother's attention, was basically a dick for the first season, and then got superpowers. This probably contributed to Danny's decision to take Promicin in the last season.
Vice-President John Hoynes on The West Wing. He was a lock for the Democratic Party's presidential nomination, until dark horse candidate Bartlet came out of nowhere and started winning primaries — with the help of a team that included Josh Lyman, formerly Hoynes's most trusted lieutenant. Worse, after Bartlet got the nomination, Hoynes was insulted by the offer of the VP slot, and accepted it largely on the understanding that it would be "his turn" next time (and that "next time" would come after only one term, because of Bartlet's MS). His resentment was routinely exacerbated by the fact that the VP is traditionally more or less a prop for the White House's agenda, so he's generally ignored unless Bartlet wants to wheel him out to lend moderate credence to his more radical policies, which Hoynes doesn't necessarily even support. (This last in particular has some Real Life parallels with John F. Kennedy and Lyndon Johnson.)
Ben Finney and James T. Kirk were friends when they were younger, until Kirk logged a mistake Finney had made aboard the Republic that could have blown up the ship had it not been discovered. This caused Finney to be reprimanded and dropped to the bottom of the promotion list. Years later Finney, still burning with resentment of being denied the captaincy he believed Kirk had taken from him out of jealousy but pretending to have forgiven him, faked his death and framed Kirk for it. When discovered, Finney breaks into a tirade about how he has "killed" the Enterprise (by causing the ship's orbit to decay) and that he doesn't care about the people he'll kill as they are "officers and gentlemen, Captains all...except for Finney, and his one mistake!"
Johnny Crowder in Justified resents Boyd over a gunshot wound he received in season 1, leaving him disabled. He also resents Boyd and Ava for their plans to move to the suburbs and leave him behind. His endless plotting against Boyd, including his decision to tell the Marshals about Boyd's arrangement to deliver Drew to the Tonins, stems from his deep-seated resentment.
Johnny also resents Colt, disgusted that Boyd would trust a man outside the family and region. Colt's incompetence and violence toward Teri only exacerbates Johnny's resentment. To be fair, however, Colt was disrespectful to Johhny when they first met.
Minor example with Ron Weasley who, although one of Harry's closest friends, becomes increasingly angry with his Butt Monkey status, in comparison to Harry's fame, vault full of gold, and the yearly chance to shine as the Chosen One, eventually coming to a head in Deathly Hallows. Ron is also resentful for being the youngest son in such a large family of talented children, so that any of his accomplishments become standard expectations (getting into Gryffindor, becoming a prefect, joining the Quidditch team, etc.) but this isn't focused on as much in the series, except for a few moments.
Snape, who always resented James Potter's good looks and charm (not helped by James being a complete ass to him). With Harry looking so much like his father, Snape unfairly transfers his resentment onto him.
It's also implied that Aunt Petunia's reactionary attitude toward the revelation that her sister Lily was a witch was partly out of envy, and this contributed to their falling out.
Draco Malfoy wants to hang out with the famous Harry Potter at the start, but gets rejected because he takes about five seconds to prove he's a haughty, mean little twit. He spends most of the rest of the series tormenting Harry over all the unwanted fame and attention he's getting and failing to match him in things like Quidditch. Way to spend your energy on someone you supposedly don't care about.
The Old Testament tells us that this is the motive for Cain's murder of Abel... of course when God Himself tells you you're The Unfavorite, maybe a little jealousy is justified.
Of course He was never actually told that, just that his sacrfice was unacceptable and Abel's was. He was even told if he did right he would be accepted.
In the New Testament, the older brother in Christ's parable of the Prodigal Son is understandably resentful when his father not only welcomes back his ne'er-do-well younger brother, but also throws a huge party in his honor. The father has to gently remind him that he's still set to inherit everything the old man owns —while the younger brother blew his entire wad when he left— and to just be happy that his brother is okay.
East of Eden, based on the Cain and Abel story, extends this over two generations.
The title character from Cousin Bette towards her wealthy relatives.
An aversion is found in Christopher Moore's Lamb with young John the Baptist. When Joshua and Biff meet John (Josh's some number of cousin some number of times removed), he's convinced he's the Messiah and has taken to aggressively baptizing younger kids. When Biff and Josh tell him that Josh (Jesus) is the Messiah, and that he's actually mostly raised the dead, John wants to be absolutely sure... and is then grateful to have that load off his shoulders. He wants to help Josh, though, so he keeps baptizing people.
Friedrich Nietzsche argued in his work The Genealogy of Morals that ressentiment, the essential reassignment of the pain that accompanies a sense of inferiority onto an external scapegoat, is the central effective force for the creation of identities, moral frameworks and value systems. Most particularly, Judaism and Christianity are presented as the creation of the weak who resent how the strong are able to lord over them, and thus create a system of morals to "invert" the natural order.
MarkPierreVorkosigan's background as a clone commissioned, biosculpted, trained, and tortured into an effective copy of Aral Vorkosigan's son pretty much insures this attitude at least as an undertone toward the little twerp in question for all that Miles seeks to claim him as a sibling. Admittedly, he has gotten a lot better.
In James Swallow's The Flight Of the Eisenstein, Grulgor resents Garro, claiming that he thinks himself above the rest of them because he came from Terra, and that is why he will not join a lodge. A major factor in his willingness to join Horus.
In James Swallow's Warhammer 40000Deus Sanguinius, believing Rafen to be dead, Sachiel admits to himself how much he resented him, from his quiet strength to his contempt for Sachiel to the way he won the respect of his men.
In Red Fury, the Flesh Tearers resent the Blood Angels, assuming out of hand that they are proud and will lord it over the other Chapters derived from Sanguinius because they came from the First Founding. Seth, their Chapter Master, tells them he intends to exploit the Blood Angels' weakness and wishes to take their position on Baal. He openly declares their chapter should be dissolved. After their battle with the Bloodfiends, and Dante's saving his life, Seth declares that these events came about so that they will remember that they are brothers not cousins.
In the Ciaphas Cain novel The Traitor's Hand, Tomas Beije profoundly dislikes his old classmate Cain, who is not particularly pious, is decidedly slack on discipline in his regiment, appears to spend a significant amount of time away from his official duties as a commissar... and happens to be regarded as one of the Imperium's greatest heroes. His efforts to discredit Cain eventually backfire spectacularly.
Several of the Forsaken in The Wheel of Time series were originally good guys who switched sides because they couldn't compare to The Chosen One leading humanity's forces. Especially notable is Demandred, who was Always Second Best, in every single way, up to and including height. Sammael and Be'lal were also notable resenters, though their hatred for Lews Therin was said to pale beside Demandred's, even though they had more direct reason.
See also Mazrim Taim, who fulfills exactly the same role towards Rand that Demandred did towards Lews Therin Telamon, to the extent that it was a popular fan theory that the two were one and the same, until it was Jossed.
This is basically Sir Apropos Of Nothing's defining character trait. Eventually comes to a head when he beats the shit out of the Designated Hero and hijacks the entire plot.
In John C. Wright's The Golden Age, The Phoenix Exultant, and The Golden Transcendence, the defining trait of the Nevernexters, and the cacophiles: with the invention of personal immortality, they will never inherit their parents' wealth, and they openly base their entire program on resenting that.
Ser Illvin dy Arbanos in Paladin of Souls is widely presumed to be this, being the bastard half-brother Arhys dy Lutez, March of a critical border fortress and son of a great statesman. However, aside from traces of irritation over his brother's Chick Magnet status ("You could duck, try it sometimes"), Illvin's main feeling toward Arhys is filial affection leavened with pity for what amounted to a fatherless upbringing.
In Tolkien's The Children Of Hurin, both Gwindor and Brandir resent the hero Turin for stealing their loves and undercutting their authority, but while Gwindor stays a loyal friend, Brandir ends up taking his resentment too far and gets killed by Turin.
Brandir maybe was resentful, but he only spoke the truth—he informed Turin that he is a Doom Magnet: a curse on his own lineage and those that help him. Turin killed him and later found out he spoke the truth, then asked his sword Gurthang to kill him, the sword does it to forget Brandir’s blood, because his death was unjust.
The demons in Tosca Lee’s Demon A Memoir are totally consumed by a double dose of resentment: towards God for rejecting them, and towards humanity for not suffering the same fate.
Warrior Cats has Ivypool being jealous of all the attention Dovewing has been getting from the older warriors and Firestar himself...though she's never realized her sister's powers yet. When she's told the truth, she's not happy at first about being lied to, but then she promises to help Dovewing out whenever she can.
Tigerstar reveals during his and Firestar's Final Battle that he became nothing the moment Firestar joined the Clan. Thus, he had waited for so long to get vengeance on his rival.
Music
PDQ Bach's A Little Nightmare Music, features a mysterious playwright from another century, appearing to accuse Salieri of murderous resentment toward Mozart. Salieri does inadvertently kill Mozart, but only because the servant PDQ Bach bumps him as he tries to poison the mysterious playwright.
Professional Wrestling
One of the most widely used angles in any form of wrestling, typically between two faces where one is arguably more popular than the other, in a tag team, or within a family.
The epic feud between brothers Bret and Owen Hart, where Owen even called his rise towards main event status as him "leaping out of the shadow" of his more accomplished older brother. Even when Owen made his Face Heel Turn at the Royal Rumble in '94 after months of build-up and tension, he was unable to get the match he craved with Bret until Bret finally relented and they opened that year's Wrestlemania with one of the event's greatest ever matches, where Owen beat Bret cleanly, but was still overshadowed by Bret winning back the WWF Championship in the night's main event.
Resentment at Hulk Hogan's popularity, combined with his intense jealousy for Miss Elizabeth led to Macho Man Randy Savage become this ("OH YEAH, YOU'VE GOT JEALOUS EYES, HULK HOGAN!"). Bonus points for the two of them actually forming a tag team known as The Mega-Powers, and their Wrestlemania match was famously known as "The Mega-Powers EXPLODE!"
After Edge won the King of the Ring tournamanent in 2001, it eventually led to his tag team partner Christian turning on him and beating him down with his own trophy, as well as a one man Con-chair-to, the team's signature move.
Molly Holly was portrayed as this in 2003 against Trish Stratus. Molly also convinced Gail Kim to help her in her cause, prompting Jim Ross to name the two "The Jealous Jezebels".
Tabletop Games
A number of the fallen Primarchs in Warhammer 40000 resented the Emperor, one or more of their brother Primarchs, or both. Perturabo has to be the standout example, as his hatred of Rogal Dorn played a major role in driving him to the dark in the first place.
In Werewolf The Apocalypse, the Shadow Lord tribe serves as this to the Silver Fangs, the royal tribe that rules over the Garou Nation.
Theatre
This is a large part of Don John's motivation in Much Ado About Nothing. He's the heroic Don Pedro's bastard brother, and recently lost a battle to him. Don Pedro forgives him and John joins the former's party, but remains bitterly resentful. The other part of Don John's motivation is that, by his own admission, he's just a massive prick who enjoys doing dickish things.
Video Games
Pictured: Kristoph Gavin became VERY angry when he found that Phoenix Wright had been chosen over him to represent a defendant. From Kristoph's point-of-view, it looked like said client had chosen Phoenix over himself because Phoenix had beat the client at poker and he hadn't. In actuality, the client wasn't paying attention to the results so much as how they played the game; he saw a ruthless streak in Kristoph's play that he deemed dangerous. He was right; Kristoph personally killed that defendant and had Wright disbarred.
Justice For All introduces Morgan Fey, who is very bitter that her younger sister had better spiritual powers than her and became the Kurain master, while she was shuffled off to one of the Branch families. So much in fact that she tries to get her sister's last daughter, Maya, arrested for murder and then murdered herself. Trials & Tribulations reveals that the entire Fey clan is full of Resenters, which is important for the backstory of the last case.
Snowe from Suikoden IV fits this trope pretty well.
In The Godfather: The Game, Monk's resentment of player character Aldo comes from how his parentage means that he will never become a made man.
Albus, bitter that Barlowe has chosen Shanoa to use the Dominus glyph instead of him, serves as the main antagonist of Castlevania: Order of Ecclesia.Averted when it turns out that Albus acted like that because he was fully aware of what the Dominus glyphs would do to Shanoa, and refused to let her use them precisely because of that, in an attenpt to protect her. He just went about it in the worst possible manner.
Hugh Baldwin feels the same way about Nathan Graves in Castlevania: Circle of the Moon. And gets brainwashed because of it.
And then there's Ortega's jealousy of Cornell's mastery of his beastman abilities in Castlevania: Legacy of Darkness. Also the real deal.
Castlevania has a lot of these. It's a good thing Eric Lecarde didn't go further down this road in Judgment.
Ulala Serizawa in Persona 2Eternal Punishment does an unintentional variant of this when Nyarlahothep takes advantages of her drunken state to get her to use the Joker Curse on Maya Amano, whom she resented for being more successful in life and in love than herself. It should be noted, however, the resentment was real, but ordinarily, she wouldn't have acted on it. Katsuya is also a fairly serious example, having thrown away his dreams of being a patissier when his father was framed for a crime to take care of his younger brother, who hardly seems to appreciate Katsuya's sacrifice. Nyarlathotep has a lot of fun shoving this in their faces at the Monado Mandala.
Junpei of Persona 3, who, struggling with feelings of inferiority, jumps at the call but gets repeatedly shown up by the protagonist. In "The Answer", Yukari becomes this to Aigis after the latter inherits the Protagonist's powers.
Chie's "shadow" persona in Persona 4 has shades of this toward Yukiko. Yosuke's Social Link reveals that he was jealous of the Protagonist, though by the time we learn this he's largely gotten over it. In both cases, it's underneath a whole bunch Ho Yay.
In the last act of the Nintendo 64 game Aidyn Chronicles, Prince Sheridan after betraying his kingdom to the powers of Chaossnaps and reveals his long buried resentment of Aloran. He always hated how everyone in the castle — his father who is also Aloran's father as well, their combat instructor, the castle cook, Aloran's childhood friend Brenna (who always fawned over Aloran while snubbing Sheridan) — favored Aloran over him. When Aloran tries to avoid him to deal with bigger problems Sheridan screams in frustration and forces a confrontation that gets him killed.
Oswald, who is understandably resentful of his younger half-brother Mickey after the latter stole the former's spotlight in more ways than one.
Dragon Age II has this in Carver, who is often overshadowed by his twin sister Bethany due to her being a mage, and by the elder Hawke sibling (the player character) due to either also being a mage or for being a more focused fighter. Player choices can let Carver overcome this, if he doesn't die.

In Tales of the Questor Rahan is revealed, at the eve of Quentyn's departure, to have tormented Quentyn so long out of resentment —- for his status as the Woobie, for seemingly skating off scot-free whenever he brings trouble down on the village, and for how he always lands on his feet.
Ho from Tower of God absolutely loathes Baam for being crazy talented and really humble and friendly about it, especially since Baam's talent put him in a very difficult position.

This also seems to be the only thing driving Kismet forward in the Whateley Universe. She hates Fey because Fey gets everything. Fey is prettier. Fey is a better and more powerful wizard, even though Fey is younger. Every time she tries to one-up Fey, it fails. She's put her team into a Team Tactics course solely to show up Fey and Fey's team. If she wasn't such a Bad Boss, her team might even succeed at it.
Also, Sharisha/Tempest, who utterly hates Chaka for being pretty, smart, having awesome powers, a team full of real friends and having heaps of people wanting to date her, especially since Chaka used to be male. Sharisha, who is fat, plain, doesn't have many friends, isn't very good at using her powers and doesn't have anyone after her, hates that a boy (which is how she sees Chaka, who is very female) gets everything she doesn't. Sadly, she doesn't realise that if she and Chaka weren't fighting, Chaka could probably help her with her powers, and if she didn't lash out at everyone, they'd like her more.
Western Animation
In the Aladdin animated series, this is a key component of villain Mozenrath's psyche: anger that Aladdin has been granted massive magical power (through the luck of having met the Genie), and become heir to Agrabah (through his chance meeting with Jasmine), whereas Mozenrath has had to sacrifice so much (most notably the flesh of his right hand in exchange for a magical gauntlet) for power.
In The Simpsons episode "Homer's Enemy", Frank Grimes' main character trait is resentment of how Homer has done well for himself despite being, well, Homer Simpson, while he has worked hard all his life and gotten nowhere.
Tigress as well. While it was assumed by all of the Furious Five that one of them would be given the Dragon Scroll, she seemed the most focused on such a goal, believing Oogway had been pointing at her—and when this proved not to be the case, she spent the rest of the movie resenting, belittling, even outright insulting Po every chance she got. Only after she got her ass handed to her by Tai Lung did she start to realize that, whether or not Po was right to be chosen, perhaps she didn't deserve the scroll after all. When Po manages to not only understand the symbolic value of the scroll and use its wisdom to defeat Tai Lung, she is convinced and is at peace with that to the point of growing much closer to the panda.
I.R. Baboon from I Am Weasel resents Weasel's fame and considers himself better, even though Weasel is a certified genius, whereas Baboon is... well, not.
Plankton of Sponge Bob Square Pants has, as his main villanous motivation, the resentful Mr. Krabs's success (and, in turn, the community that made Mr. Krabs a success), especially in comparison to his own restaraunt (which Plankton regards as superior, hence his ongoing attempts to steal the Krabby Patty formula.
Also seems to be reversed at times. Krabs at the very least has a rather intense rivalry with Plankton and is obsessed with gloating his success in his face. Whenever Plankton seems to have even minor success that makes his own resentment fade, Krabs obsessively tries to destroy him, intent on having him back in his shadow.
Avatar The Last Airbender both subverts this and plays it straight: Though Prince Zuko would initially appear to be one of these characters, his dialogue would seem to reveal that almost all of his anger is directed inward at what he perceives to be his own failings, allowing him to be much more calm, once he makes the Heel Face Turn. However, though she hides it well, Azula's secret resentment of Zuko, and the love their mother felt for him and not for her (at least so she thinks, its really all in her mind. Her mother was more worried about her then scared), ends up contributing greatly to her Villainous Breakdown. The person Zuko resents isn't any of the heroes - instead, he resents Azula for being a better villain than him, and for getting the approval (Ozai probably isn't capable of anything that could be called "love") of their father. Apparently, said father like to say that Azula was "born lucky," whereas Zuko was "lucky to be born." Ouch.
Danny Phantom has Vlad Masters. Despite being a billionaire celebrity and possessing half ghost powers, Vlad is resentful towards his best friend Jack because he was the one who married the love of his life. Not to mention fathering a son who is half-ghost, a person who in Vlad's eyes, should rightfully be his! Naturally, he spends most of the series trying to kill Jack.
In a nice bit of irony, in an Alternate Universe caused by Danny meddling in the past. He does marry Maddie but turns out to be a controlling husband who refuses to let her do ghost hunting related activities because it reminds him of Jack. Yes even when he gets what he want, he's still the resenter.
Tucker Foley, but to a lesser extent. Prior to obtaining his ghost powers, Danny was on equal grounds with Tucker. The two were best friends who shared everything. Then Danny gets all the awesome powers and Tucker is stuck being the Butt Monkey. One episode showed him acting on his resentment via a [unintentional] deadly wish that nearly had him kill Danny.
Indeed, seeing the monster his wish had created helps Tucker move past this trope.
Initially, Raven appears to be this character in regards to Terra on Teen Titans: angry that Terra has apparently managed to control her powers so easily, while Raven still must meditate constantly to keep hers in check. However, since it turns out that Terra got her control from working with Titans Arch-Enemy Slade, the resentment was probably justified.
In ThunderCats (2011), Lion-O and Tygra are Resenters to each other. Lion-O resents Tygra for being the Always Someone Better and Compassionate Critic whom nearly everyone in their kingdom — even his own father — preferred over him. Tygra resents Lion-O for being The Chosen One of the Sword of Omens and apparently Cheetara. That second one is particularly galling for Tygra since he's nursed a crush on Cheetara since childhood. Lion-O and Tigra's mutual resentment fuels their Sibling Rivalry, though Lion-O still wholeheartedly trusts Tygra and doesn't believe that Tygra would ever betray him even after hearing a prophecy stating Tygra will do just that.
They do eventually start to get over it when Cheetara makes it clear she wants a relationship with Tygra, and Tygra, in charge after Lion-O's (temporary) death, finds out that he isn't as successful a leader as Lion-O had proven to be.
