Yuru Yuri: Sakurako becomes the very definition of this when Himawari spends time after school teaching Chinatsu to knit a scarf for Valentine's day instead of tutoring Sakurako. If this weren't a typical comedy anime, the episode probably would have ended with them becoming an Official Couple.
Also, Momiji points out to Kyo that some other man might marry Tohru if he doesn't overcome his feelings and get her, in order to inspire him. Indeed, when the new school year begins, he overhears some classmates discussing that she's pretty, looks dumb and easy to seduce; this inspires him to walk over to her and look possessive, to drive them off.
In the Naruto anime, Sakura is unexplainedly jealous of any girl that takes Naruto's attention away from her, despite her claim in Part 1 that she doesn't even like him. This was also seen at least once or twice in Naruto Shippuden.
Additionally, Sasuke grows jealous when he discovers that Naruto is advancing faster than he is, eventually completely annihilating his better judgment and going off to join Orochimaru. It just goes downhill from there.
This jealousy was spurred on by another bout of jealousy. Sasuke was jealous that Itachi had focused his attention on Naruto rather than him, even if that attention was entirely negative. This spurred him into fighting Naruto, which revealed the difference in their strength.
Naruto was jealous of Sasuke long before Sasuke was jealous of him, however; both for his skills as a shinobi, and because Sakura was a Sasuke fangirl, while she disliked Naruto. One of Naruto's primary motivations early on in the series was to show up Sasuke and win Sakura's affections.
Lee gets jealous of Naruto and Sasuke despite having curbstomped both of them; the former for defeating his rival Neji, and the latter for getting to fight Gaara in the finals and having theSharingan.
In Skip Beat!, this is explicitly shown as the reason Kyouko didn't have any female friends back in elementary or junior high school: since she was too close to School Idol Shou, the other girls outcasted her. Several other characters in the series have this as part of their personalities: Shou towards Ren, that Rich Bitch against Kanae, a certain band leader toward Shou...
SHUFFLE!: Kaede directed towards Rin. More so than the other characters of Rin's harem, anyway.
Nadia: The Secret of Blue Water: During the Nautilus episodes, a triangle of jealousy emerges between Grandis, Electra, and Nadia... for different reasons. Grandis is jealous of Electra's love for Nemo. Electra is jealous of both Grandis's attraction to Nemo and Nadia out of her own fear of losing Nemo (she tries to suppress it, though). Nadia, meanwhile, becomes jealous of Jean's friendship with Electra, to the point where she fears she may lose him to the latter (when in fact, nothing romantic is happening between either). Even Sanson is somewhat implied to be jealous of Captain Nemo at one point... although partially out of fear for Grandis' usual amorous fickleness and failed love affairs.
In Lovely Complex Otani was jealous when Risa had a crush on Maity sensei, leading him to realize/confess his feelings. Later, he is also jealous and possessive towards Risa on several other occasions. To say nothing of Risa, to a lesser extent, over Otani as well. Then there's Mimi who is a Yandere over Otani. She gets better, though.
In Kekkaishi, Yoshimori is jealous of Tokine always paying attention to his older brother. Also Tokine was seen obviously jealous when Julia was crushing on Yoshimori.
Sailor Moon: Usagi towards any girl who expresses interest in Mamoru. Queen Beryl, Galaxia, Ann, and Nehellenia are jealous of Usagi because of her romantic involvement with Mamoru. Then there's Ali and Prince Diamond, who are both jealous, to a T, of Mamoru.
Black Cat: Train + A Girl = An insanely jealous Creed.
Full Metal Panic!: Ditto with Gauron, only it's Sousuke + Kaname = One very pissed off Gauron. It doesn't even have to be with Kaname. Sousuke + anyone else (including True Companions / father figure) = very pissed off Gauron. Kashim should not be with anyone else.
Yui in Fushigi Yuugi is jealous of both Tamahome and Miaka, constantly trying to come between them.
Peach Girl revolves around this Trope. Let's see...
Sae is jealous of Momo to the point of hating her, but she possibly admires her as well, otherwise she wouldn't fuck with Momo's life so much, and try to steal Toji away from her. Toji and Kairi are also jealous of eachother because they both are competing for Momo's attention.
In Daa! Daa! Daa!! Miyu has been jealous of Kanata's old childhood friend, and Kanata jealous of that older guy Miyu had a crush on.
In Magic Kaito Kaito was jealous that Aoko felt safe with the teacher while they were exploring the school after dark and that she didn't partner with him and that she didn't seem bothered by Hakuba asking her out.

In Love Roma Hoshino has been jealous of Negishi's old classmate.
In Zero no Tsukaima both Louise and Saito have shown IMMENSE jealousy whenever the other showed interest in anyone but them (especially Louise).
In Revolutionary Girl Utena:, the very green-haired Kyouichi Saionji is the personification of envy. He's envious of his best friend and classmate Touga because he seems to be better than him on every field, he's envious of the chairman Akio because, well, because he's the fat cat, and he's envious of Utena because hey, she defeated him, she got Anthy as her "bride" and she's now the "official" Prince... on second thought, poor guy. Okay, maybe his eyes aren't green, but he has a "green" theme going on (hair, pants, duelist rose).
This is also Shiori's motivation. She felt inferior compared to Juri, so she began hanging out with her to manipulate her feelings, culminating in stealing a boy who wanted to ask Juri out. The real tragedy is that this worked and turned Juri into a Broken Bird...because she was in love withShiori from the start.
In Tokyo Crazy Paradise both Ryuji and (eventually) Tsukasa have been jealous when the other showed any interest in anyone but them.
In The Prince of Tennis, Tomoka's jealousy of almost any girl who talks to Ryoma (aside of Sakuno), Kamio's jealousy of any males who get too close to his crush An, and Yuuji's possessiveness of his partner Koharu are quite played for laughs. In the manga, Sakuno also has a brief moment of jealousy when Kotoha from Tsubakikawa appears and claims to be in love with Ryoma, but unlike the others she manages to set it aside.
Yuuta Fuji's jealousy of his older brother Shuusuke and Kurumi Iijyuin's jealousy of her older twin sister Narumi make both of them rebel against their more succesful siblings. A big part of Shuusuke's earlier Character Development is tied to him first hiding his own pain and later managing to resolve the issue with Yuuta; later, he uses his experience to help Kurumi reconcile with Narumi.
Takuma Fudou from Get Backers is shown to be this... and not towards Ban, but towards Ginji. To elaborate, he's jealous of the attention that Ginji gets from Ban, and he actually tells Ginji that he dislikes him because Ban doesn't even notice him when Ginji is around. He then proceeds to try to Murder the Hypotenuse while telling Ginji that Ban's eyes aren't on him because Ginji is in the way.
In the live-action adaptation of Uzumaki, it's Mitsuru, one of Kirie's schoolmates, who becomes this. He practically makes deep gouges on the tree he's hiding behind while watching Kirie and Shuichi, and the look on his face is that of sheer jealousy and hatred towards Shuichi.
This is why Natsume is often such a jerk to Sae: on the day on the entrance ceremony, she found herself having to go alone, the train (which normally takes 42 minutes on top of the 10 minutes by bicycle) had to make an emergency stop, she took the wrong street, and finally, she found the shoe locker she thought was hers to be full. Sae directed her to the next set of lockers, and they talked as they hurried. Now, Natsume latched on to this, thinking that they might become best friends. She was unable to meet up with Sae, and didn't see her until ten days later, and upon greeting her, found her with Hiro, who was in the same class and apartment. This triggered something inside her, and, well... she realized as she sulked after her initial outburst that Sae didn't do anything wrong, but that didn't prompt her to change. (As a side note, Natsume does have green eyes.)
Miu often feels jealousy over Nobue's preferential treatment of Ana and Matsuri, and sometimes competes for her attention even when she's trying to take care of her sister when she has a cold.
Wendy Garret of GUN×SWORD displays jealousy whenever other women show too much interest in Van. (She's also green-eyed, but that's probably a coincidence!) It is just possible that some of Van's dislike of Joshua also falls into this trope, but that may be a stretch.
Touma's mother looks really scary whenever her husband looks at another woman.
Every member of Touma's harem gets angry when they see him with another girl.
Accelerator and Hamazura's harems get mad when they see the two hang out with Fremea, even though she's only a little girl.
Tekkaman Blade: Tekkaman Evil/Shinya is loved by his family, but feels like he's being considered the weak one as the 'good' treatments was given to Blade/Takaya, for instance, when they both were nearly drowning, Shinya was saved instantly, but Takaya was told to just save himself... yet Shinya was JEALOUS because the family trusted Takaya's strength over his own strength. Kind of complicated, yes.
First, pre-Eclipse Griffith grows quickly jealous when he notices that Guts and Casca have become an item. It is unclear who he envies more due to his ambiguous sexual orientation. It's possibly both.
Averted with Judeau. Despite his unrequited crush on Casca, he knows he has no chance whatsoever, noticing the bound she and Guts had formed, even before either of them would realize it. Preferring to lose with honour, he helps a lot in the cementing of Guts and Casca's relationship, even going as far as encouraging Guts to take Casca away with him, by force if necessary.
During the Griffith rescue operation, Casca had the Green-Eyed Monster attitude toward Princess Charlotte for a bit, since she admitted that she was still worshiping Griffith like before, even after she and Guts made love for the first time earlier. She tried reconciling to herself, but ended up saying the wrong thing to Guts about the matter, which succeeded in pissing Guts off even though HE admitted to himself that he couldn't take his mind off Griffith. But don't worry - they made up later.
Then, post-Eclipse, there's the unspoken rivalry between Sonia and Charlotte. Charlotte is Griffith's Meal Ticket, even though he acts in order to make her feel like he actually values her for herself and NOT her birthright. Sonia is a faithful servant to Griffith, gifted with clairvoyance, and as such considers herself the only girl worthy of him. Sonia is very jealous of Charlotte but her nascent and reciprocated relationship with Irvine might wash it all out.
There's also the jealousy Farnese feels for Casca for being the object of Guts's affection. Farnese is technically betrothed to Roderick, who is himself quite handsome, but she definitely has a crush on Guts who doesn't see her beyond being Casca's caretaker. Farnese even breaks down in front of Casca, telling her that she's really ungrateful to ignore Guts after all he did for her but Casca being insane and regressed to infancy, it doesn't really do anything, although Casca seems to understand Farnese's distress.
Finally, there's Schierke's Precocious Crush on Guts but, unlike Farnese, Schierke only has shades of this and knows deep down that she's way too young for Guts (he is more than twice her age). Plus, her Toy Ship moments with Isidro also seem to drop some hints about she may eventually like.
In the manga of Brigadoon: Marin and Melan, one of the first signs that Melan is developing romantic feelings for Marin is the jealousy or anxiety he displays when he sees her alone (and half-dressed) with another love interest.
Soul Eater has the Envy chapter of the Book of Eibon, although we only see what Soul and Maka have envy for; Maka is jealous of Liz and of music itself, since Soul loves it so much while she can't even understand it, despite studying it ad nauseum. She's also jealous of/worried about other meisters who claim to fit Soul better - especially girls. Soul is jealous of his older brother, Wes, for his superior musical talent. It is also implied that he chose to be Maka's partner because she didn't understand music, and he feels guilty for that. What makes this even better is that Maka actually has green eyes.
Madame Red in Black Butler. The love of her life Earl Phantomhive (Ciel's father) married her beloved sister. She tried to be happy for them but when Ciel was born, jealousy started to consume her. Even when Ciel's parents died in the fire, though devastated, she envied her sister for dying with someone she loves.
Vegeta from Dragon Ball Z has got to be the epitome of this trope. Throughout the entire series Vegeta envies Goku because no matter how hard he trains and fights he is never able to surpass Goku. This becomes a literal case of Green-Eyed Monster when Vegeta becomes a Super Saiyan (the transformation gives you green eyes) and despite becoming the warrior of legend that the Saiyan Race had admired for thousands of years 'still couldn't let go of his pride. During the era of peace after Goku died he still finds a reason to be jealous because he sees that Goku's family life is more loving and meaningful than his is as Goku's family supported him and made him a better fighter while his didn't show the same results. It is only when Vegeta lets go and admits that becoming better than Goku isn't all there is to his life that he truly shines as a warrior and becomes a good guy.
Bleach: After Ichigo sinks into depression because his failure to protect resulted in his friends getting badly injured, Orihime can't cheer him but Rukia does by making him resolved to never let any of his True Companions get that injured again. Orihime believes she's incapable of bringing Ichigo out of despair leading her to feel jealous of Rukia's ability which has made her feel useless. This trope is immediately subverted when, instead of becoming bitchy or bitter, Orihime gushes about how wonderful and amazing Rukia is and how bad she feels to be jealous of such a good person. Rangiku resolves the issue almost immediately for her and a few chapters later it's confirmed Rukia and Orihime are very good friends and training hard together.
Captain Brian, Lostman's superior in the Navy in Moonlight Mile. Annoyed at being repeatedly shown up by Lostman, he intercepts the orders for him to be transferred to NASA, refusing to release him from his command without flying one last mission for him, stating that while flying the Shuttle is more honorable than flying fighter jets, until the orders go through, Lostman is still a soldier, and a soldier's highest duty is to risk his life for his country. Then he lets Lostman get shot down. Lostman's lost behind enemy lines for over a year before he comes back, by which time he's joined NASA... and Lostman ends up his SUPERIOR.
In Candy Candy, Annie Brighton confesses to Candy White Andree, during an emotional breakdown, that she has always been secretly jealous of her. This is because Annie is a Fragile Flower who is very scared of reaching out to others, whereas Candy is a fearless Plucky Girl who always reaches to the rest — even in the times when they were heartwarming orphans, Annie always felt less appreciared and loved than Candy was. It's really not helped when the boy that Annie likes, Archie, says that despite caring for Annie, he likes Candy as well. (Partially because he is jealous of her other current love interest, Terry).
Loki is Marvel's personification of this trope to the point that he has actual green eyes. His constant envy of his elder brother, Thor and his need for love from his father warp him into a villain. Most of his mischief is about getting attention and love. His history as an abused child doesn't help. Neither did Odin's blatant favoritism towards Thor. Odin adopted Loki out of obligation and guilt. Ironically he creates his own destruction by doing so.
In the Fantastic Four, this is the reason Doctor Doom hates Mr. Fantastic. He can't stand the fact that Reed Richards is smarter than him, and has beaten Doom every time he has tried to kill Reed and/or Take Over the World. In addition to those few extra IQ points, Reed also has everything else Doom doesn't have, from worldwide respect all the way down to unmarred good looks.
Why does Lex Luthor hate Superman? Because Lex worked his whole life to gain power and respect, while Superman was handed his powers by a quirk of genetics and won the hearts of Metropolis without any effort at all.
Confirmed in Blackest Night, wherein Lex is bound by Wonder Woman's Lasso of Truth and is forced to admit to himself and everyone around him that: "The truth is...I really want to be Superman."
It also probably isn't a coincidence that modern portrayals of Lex in the comics often have green eyes.
Haazen from Knights of the Old Republic (the comics) is this trope — he was consumed years ago by his jealousy of his friend (and later employer) Barrison Draay's wealth, good looks, talent with the Force, and luck in love with the girl Haazen was also sweet on. This lead him to ultimately arrange Barrison's assassination and then spend decades concocting an Evil Plan that would pervert everything Barrison stood for as well as his family name, while ending with Haazen ruling the galaxy from behind the scenes. And if would have worked if Zayne Carrick hadn't convinced Barrison's son Lucien that this wasn't what his father would have wanted.
Guy Gardner hates Superman because his girlfriend Ice admitted that she thought Superman was cute. He still hates him to this day.
The special power of Convolvulus in Astérix and the Roman Agent.
Envy of the Seven Deadly Sins in the DCU can turn anyone, hero or not, into a Green-Eyed Monster. Under its influence, Green Arrow once succumbed to his own envy of Batman over, well, everything, and tried to kill him.
Thomas Elliot, aka Hush, dedicated himself to destroying Bruce Wayne out of sheer envy. The way he sees it, Bruce was "lucky" that his parents died when he was a kid (and getting all of their money) — Thomas, on the other hand, had to go to all of the trouble of cutting his parents' car's brakelines and later smothering his horrible mother to get access to their money.
Veronica Cale is this to Wonder Woman. She thinks that an Omnidisciplinary Scientist billionaire magnate who worked her way up from rather humble origins like herself is more deserving of the title than a magical princess like Diana. If she wasn't also a Mad Scientist who kills innocent people and turns others into living weapons she might actually have a point.
In Joseph Jacobs's "Kate Crackernuts", the Wicked Stepmother has her stepdaughter Anne's head turned into a sheep's head because she is more beautiful than her own daughter. (Somewhat subverted; her own daughter Katie is in fact the heroine of the story, opposing her mother since she actually likes Anne.)
Except, as it turns out, she never cared about that — she was, however, jealous of Rarity's relationship with Razorwing, and tried to get them to break up so she could have Rarity for herself. This backfired horribly, and ended up leading to her friendship with Rarity falling apart.
In the My Little Pony: Friendship Is Magic fanfic A Delicate Balance, Fluttershy isn't at all happy that Twilight's infatuation with Applejack means that they can't spend as much time together. Fluttershy being Fluttershy, she feels awful about the fact that she's putting her own feelings before Twilight's and tries to be supportive of Twilight's relationship anyway.
Sakura in A Growing Affection is none too happy that Naruto moved on and started dating Hinata. She does admit to Lee, however, that it might be that Laser-Guided Karma finally caught up to her.
(bitterly) "It's funny. He (Naruto) used to like me but I was so busy trying to get Sasuke and he made me miserable. Now I like him but Naruto is with Hinata and they're happy."
Grimlock in the Transformers fanfic A Child Shall Lead Them. He is not happy when fellow Dinobot, Swoop, ends up getting the Matrix and becoming leader of the Autobots, the position he's always coveted. He gets better and ends up serving as a mentor figure to his teammate.
Kakashi calls Sasuke out on this in Legacy Of The Rasengan:Naruto. Despite knowing about Naruto's life Sasuke is jealous of Naruto's power. Kakashi points out that A) Sasuke is being very childish (because Naruto has something he doesn't), B) Sasuke knows for a fact Naruto only uses the Kyuubi's charka as a last resort and C) because of B, Naruto works and trains harder than anyone in his age group going so far as to be a Combat Pragmatist and Obfuscating Stupidity to get the drop on people.
Remy the Rat from Ratatouille was jealous that Colette could get public recognition for her culinary prowess and he couldn't.
Chick Hicks, the villain of Cars, is a bright green racecar. His envy of The King's success wouldn't be such a problem if it wasn't so personal. What he does on the final lap demonstrates just how much it's twisted him.
This is Woody's Fatal Flaw in Toy Story; a nice guy otherwise, but competition for his position as Andy's favorite toy leads him to trouble, and his better nature leads him into more trouble.
Somewhat averted in Pinocchio, as there were no jealous characters. As the puppet lies to the Blue Fairy about why he didn't go to school, he explains that "there were these two big monsters with big green eyes" that put him in a big sack and Jiminy Cricket in a little sack. All the while, of course, his nose grows.
The reason why "going turbo" is a bad thing in Wreck-It Ralph besides the fact that a character can die permanently in a game that is not theirs. Turbo was the protagonist of an 8-bit racing game who grew upset and jealous that a new racing game was becoming more popular than his game. He decided to enter that game which caused glitches to appear and got both games to be decommissioned. He still hasn't learned his lesson as King Candy.
Cinderella III: A Twist in Time gives us Anastasia, who is very jealous of Cinderella, living a wonderful life with her true love while she has a miserable one and no love. This starts the plot when she steals the Fairy Godmother's wand.
Anastasia:(to Cinderella) I want what you have.
Randall Boggs in Monsters, Inc., who is also literally a green-eyed monster, had grown incredibly tired of being second-best to the Mike-Sully team in scaring children. We find out in Monsters University that he was Sully's superior in scaring for some time but was humiliated by Sully at his biggest chance to prove himself, and in front of practically the entire student population, that he developed a permanent grudge to Sully.
Film — Live-Action

Bicentennial Man shows one of the few thing-human-human cases of Green-Eyed Monster. Andrew, an android, sees Portia about to marry someone else, a person who has a very prominent chin, which Andrew constantly makes fun of behind his back, to Portia of all people.
Even though he's wealthy like Tony, Justin Hammer definitly envies Tony's talent and success. His technology throughout Iron Man 2 is described as a joke and a failed knock-off of Stark's. His jealousy is even shown when he's talking to Stark or mentioning him. Heck most of his motivation in the film is to upstage Stark.
Margot in All About Eve is very insecure about her relationship with Bill and sees even Eve's most innocent behaviour as an attempt to steal him away. It turns out she's right!
In The Count of Monte Cristo, envy is the motivating force of two of the conspirators — Danglars is jealous of Dantes' success, and Fernand of his fiancée.
Demandred in The Wheel of Time became evil because he envied the fact that Lews Therin was slightly better than him in every way. Also, Lanfear envied Ilyena for marrying Lews Therin. The same applies to Sammael, who was as skilled a general and sportsman as Lew Therin but felt that his height was the reason he was the less honored of the two. Be'lal (one of whose nicknames is "The Envious" was reputedly extremely jealous of virtually everyone; Lews Therin, Lanfear and Ishamael amongst them. A case could be made this was true of a lot of the Forsaken, many of whom were prominent Light side generals or otherwise decent figures but jealous of the acclaim given to the chosen leader Lews Therin or perceived general lack of acclaim for themselves. Not all though. Semirhage in particular may have been the greatest healer in the world but she was also a vicious sadist long before the Dark One appeared, and Ishamael, as Elan Morin Tedroni, seems to have switched sides for philosophical reasons.
In Dan Abnett's Gaunt's Ghosts novel Ghostmaker, Inquisitor Lilith actively tries to foment this between Gaunt and Corbec. Gaunt slaps her down because he realizes she's doing it, and she doesn't need to, when he is willing to work with her.

In Alexander Pushkin's Mozart and Salieri, Saliery explains how he hates Mozart for being so talented while never having to strain where he, who dedicated his entire life to music, lacks such talent. This is definitely a Historical Villain Upgrade.
In C. S. Lewis' Till We Have Faces, a retelling of Psyche and Cupid, Orual hears that she persuaded Psyche to bring in the lamp at night and so lose him, because she was jealous. Infuriated by this injustice, she writes her story to make the truth known. Writing it, and the events afterwards, reveal to her that she was jealous: having raised Psyche from childhood, she was jealous of Cupid.

In Wen Spencer's Endless Blue, Mikhail feels deeply guilty that (in the Back Story) in his jealousy that Turk did not have to attend formal functions and got a trainer rather than a tutor, he did not consider what the trainer did until he accidentally stumbled on the Cold-Blooded Torture that was training for Reds. He put a stop to it at once, but thinks he should have thought earlier. Hardin reveals that he was jealous of Mikhail, because his Royal Blood ensured that he would be, at least, a footnote in history, and deliberately sabotuged his career because of it.
Harry also experiences this when he sees Ginny kissing Dean. It's described as a roaring monster in his chest.
Ivypool from Warrior Cats has this towards Dovewing because of her powers. But this is only because she doesn't know of her powers yet, and she gets really tired of living as her sister's "echo." However, she overcomes her jealosy when Dovewing reveals her powers after hearing Tigerstar's plan.
Foxheart in regards to Yellowfang liking Raggedstar, thus making the former's life hell for her.

Each of the villains in the Keys to the Kingdom series represents a deadly sin, with Superior Saturday representing envy. She has become absolutely consumed by the fact that Lord Sunday controls the Incomparable Gardens (the epicenter of the universe), and she does not. She spends ten thousand years attempting to correct this fact through the following means:
Turning her demesne into an immense tower to try to breach the underside of the Gardens.
Attempting to destroy the four Drasil trees which are forever growing and taking the Gardens out of reach.
In her titular book, she succeeds by sinking two sevenths of the House into nothing, an action of such catastrophic affect that by one of the last chapters of the book, nearly all of the House has been consumed.
Attempting to assassinate various figures of power.
Attempting to remove Arthur, the protagonist and rightful heir to her demesne and Lord Sunday's, from power via various means.
Betraying one of her closer friends and turning her into a Leviathan rather than letting her give power to Arthur or another heir.
and inflicting amnesia upon the Piper's Children because of a prophecy that states that doing so will prevent Arthur from winning.
In short, she would be the Big Bad if it weren't for the fact that Lord Sunday was so much more powerful than she.

However, when the Witch of the Waste kidnaps her to lure Howl out, Sophie goes out to rescue her, believing that Howl loves Miss Angorian and attempts to pull I Want My Beloved to Be Happy. Turns out Miss Angorian was the Witch of the Waste's fire demon and that Howl loved Sophie the whole time.
Used in A Song of Ice and Fire as part of the complicated Psychotic Love Triangle that forms the backstory of the Tully Sisters and Petyr "Littlefinger" Baelish.

Both characters take this envy to extreme, Yandere levels, resulting in Petyr manipulating Lysa into becoming his accomplice in kicking off a continent-wide civil war.
Bonus points for Littlefinger actually having Green Eyes.

Caroline Bingley is venomously jealous of Elizabeth Bennet in Pride and Prejudice, because Mr. Darcy clearly admires Elizabeth and is completely oblivious to the fact that Caroline wants to marry him. In her mind, at least; while Darcy clearly admires Elizabeth from early on, towards her it's suggested that he's adopting the time-honoured 'ignore-her-and-maybe-she'll-go-away' approach.
Also in the Jane Austen universe, Jane Fairfax rejects efforts by Emma Woodhouse to be friendly, because she's secretly engaged to Frank Churchill, who pays attention to Emma as part of the coverup, and even though she knows Emma's completely out of the loop she doesn't like it. Later, after The Reveal, she does admit to having been totally unreasonable about it.
And meanwhile, Mr. Knightley is hideously jealous of Frank Churchill for the same reason, because he's secretly in love with Emma.

In Robert E. Howard's "The Shadow Kingdom", Kull envies the lack of formality at the Pictish banquet.
In the Chinese Cinderella story Bound by Donna Jo Napoli, this was why Xing Xing's Wicked Stepmother treated her like she was a slave. Xing Xing's mother's last request was that Xing Xing would take care of all her father's needs more than anyone else, which she happily did and her father loved her more than the stepmother and his stepdaughter. In some ways, Xing Xing was closer to her father than her stepmother was to him.

In Gene Stratton Porter's The Song of the Cardinal, the cardinal envies the other birds while awaiting a mate.
he envied the blackbird his glossy, devoted little sweetheart, with all his might. He almost strained his voice trying to rival the love-song of a skylark that hung among the clouds above a meadow across the river, and poured down to his mate a story of adoring love and sympathy. He screamed a "Chip" of such savage jealousy at a pair of killdeer lovers that he sent them scampering down the river bank without knowing that the crime of which they stood convicted was that of being mated when he was not. As for the doves that were already brooding on the line fence beneath the maples, the Cardinal was torn between two opinions. He was alone, he was love-sick, and he was holding the finest building location beside the shining river for his mate, and her slowness in coming made their devotion difficult to endure when he coveted a true love; but it seemed to the Cardinal that he never could so forget himself as to emulate the example of that dove lover. The dove had no dignity; he was so effusive he was a nuisance.
In A Reluctant Queen by Joan Wolf, a retelling of the story Esther from the Bible, King Ahasuerus's close friend Haman grew jealous of Ahasuerus's new wife Esther, with whom the king was deeply in love. He also grew envious of Coes, another close friend of Ahasuerus, when the king had summoned Coes during an assasination attempt on his life but not Haman. And his jealousy towards Esther's uncle Mordecai, whom the king grew to like, would eventually lead to his own death.
In a trilogy series called Dogs Of The Drowned City, Shep's friend Zeus gets jealous because Shep seemed to care more for the smaller dog breeds instead of him and the bigger breeds.

Zeus calls him out on it, and this causes him to run away from the pack and form one of his own.
In Michael Flynn's Spiral Arm novel In the Lion's Mouth, Ravn recounts how she seduces Donovan to give them a pretext to talk, and Bridget is furiously jealous despite not having any oaths between them, and despite her long having used such a tactic.
The happier state In Heav'n, which follows dignity, might draw Envy from each inferior; but who here Will envy whom the highest place exposes Formost to stand against the Thunderers aime Your bulwark, and condemns to greatest share Of endless pain?
In C. S. Lewis's The Four Loves, he discusses how this trope is common with either erotic love or affection; agape is needed to withstand it.
In the Deryni works by Katherine Kurtz, Conall Haldane becomes envious of his cousin King Kelson's political and magical power, and he covets Rhothana Nur Hallaj, partly because she's a beautiful princess, and partly because he knows Kelson loves her.
In Buffy the Vampire Slayer Faith envies Buffy for being the "main" slayer, having friends, family, love, acceptance, etc. So she envies Buffy's life in general — right until she has to lead the charge.
In both Buffy the Vampire Slayer and its spin-off Angel, Angel has been shown quite frequently, despite having left her for her sake, been openly jealous towards Buffy's love interests or suitors, especially to Riley and Spike. So has Spike; the episode "The Girl In Question" has them try to find her when they find out she was dating their former rival, their excuse being they were worried about her.
The brotherly relationship between Frasier and Niles Crane is dominated by this trope.
Farscape had an episode actually called Green-Eyed Monster, in which Crais' jealousy of Crichton (and vice-versa) nearly led to Crichton's death. It also led to John telling Aeryn about his feelings, again. To be fair, the near death was courtesy of Talyn, not Crais. He actually had him Thrown Out the Airlock.
Oh come on, Talyn gets all his ideas and feelings from Crais, pretty much. He's just a very powerful baby who wanted his Mummy and Daddy to stay together - though, admittedly, the fake sex tape of Crais and Aeryn isn't something most toddlers would come up with.
Friends: Ross towards Paolo. Chandler towards Richard as he believes for a long time that he's still the love of Monica's life and is sophisticated, mature, an eye doctor and and able to grow a moustache. After they're married Monica points out how silly this is given she chose him over Richard several times. As an Insecure Love Interest he has trouble acknowledging this. Also worth remembering that all his previous girlfriends cheated on him, so his fears aren't exactly foundless.
Rachel and Phoebe are also this towards Monica and Chandler relationship, as they're depressed about not having anyone themselves. Lampshaded in Season 6 when Chandler's planning to propose and they say they're only 2% jealous...then 10%...then 20%...
Ross is this repeatedly. When they begin dating, he is extremely jealous of Rachel's colleague Mark, despite the fact that Rachel shows no romantic interest in him. He is also jealous of Emily's burgeoning friendship with Susan (Carol's lesbian lover), believing she will steal Emily from him. Monica points out that his divorce from Carol must have really done a number on Ross since in high school, Ross was not a jealous person despite the fact that ALL of his girlfriends were cheating on him.
In Desperate Housewives episode Back in Business, Mary Alice's ending narration focuses on the various types of envy, stating that if you look carefully at the people near you, you may spot a green-eyed monster.
iCarly: Freddie suffers this in iLike Jake and iDate A Bad Boy. Carly also gets this like whoa during the recut version of iSaved Your Life. When a slutty girl comes up to Freddie and offers him weekend sex with her whilst her parents and brothers are away, Carly grabs Freddie by the shoulder, embraces him and starts French kissing him so the girl will take the hint that Freddie is taken, much to his surprise (and approval).
In Robin Hood, Guy of Gisborne envied Robin his popularity and status as a national hero, and the love of Marian.

An episode of Hercules: The Legendary Journeys had Cupid turn into a literal green-eyed monster when the woman he was in love with fell in love with Hercules (who reciprocated due to being struck with one of Cupid's arrows).
Prince Arthur a couple of times on Merlin. He responds to the sight of Lancelot and Guinevere holding hands by throwing a Big Sulk (and this is before he and Guinevere are in a relationship), and later gets riled at Gwaine for flirting with her. The fact that both knights have been reinstated at Camelot gives you the feeling that this is heading somewhere...
One of the longest running jokes in Everybody Loves Raymond is how much Robert envies his brother, Raymond. In his rants, he would talk about how "Everybody loves Raymond", how his mother favors Ray over him, how much successful Ray is compared to him, and how he has a better life than him(at least in his eyes). It gets to the point that when ever Ray fails at something or doens't get what he wants, Robert would find joy in this and openly mock him for his shortcomings.
Mash has Margaret, who is jealous of Frank's wife. When she finds out Frank bought a set of expensive pearls for his wife and a second, cheaper set for her, Margaret devises a plan to get Frank to swap out the cheaper ones so she will have the more expensive necklace and Frank's wife will get the cheaper set.
The tables get turned when Margaret marries Donald Penobscot. Frank's own jealousy causes him to kind of lose his marbles and he ends up sent back to America on a Section 8.
Lex: You were always one step ahead of me. Clark: It wasn't a competition. Lex: Of course it wasn't; you're simply better than the rest of us. Clark: And that always killed you, didn't it? Lex: No. What killed me was that you didn't evenwantit. You rejected it. If I had your destiny, I would have embraced it.
In the Castle episode "Eye of the Beholder", Castle and Detective Beckett are joined on their investigation by Serena Kaye, a classy, attractive insurance investigator who is clearly attracted to Castle and whom Castle begins to find intriguing in return. Not entirely surprisingly, Beckett spends most of the episode seething with badly-concealed jealousy about this.
In general, Beckett seems prone to struggling with her inner-teenager-with-a-case-of-this whenever other women attract Castle's attention.
On Leverage, Parker is this during the episode The Double Blind Job with regard to Hardison being friendly with the client. She later breaks a beer bottle as she is watching them talk.
This comes up periodically in Supernatural; people who don't know the boys see that they're handsome, tall, competent, charming, good liars, etc., and conclude they have it easy. As the stars of one of the most depressing shows on television, this is emphatically not true.
The loser behind the problem in the wishing well episode says something to the effect of them having it easy with their great looks and cool car, and they assure him in deadpan that they are absolutely miserable. This is a little surreal, in that it's true, but they say it like they're remarking on the weather. On the other hand, Sam lies to the asthmatic warlock kid in 'Swap Meat' that he'd love to have his life without the demon bounty hunters and blood addiction problems and responsibility for the Apocalypse and all that. Actually, he'll take all that rather than be that kid with the collegiate future locked in stone by his asshole family, and a no-good body. Probably the most significant factor being that by Season 5 Sam has long since grown uncomfortable with restrictions on his ability to kill the fuck out of his problems, and is not actually fit to live in society anymore, even if he is wearing a white hat again.
Played for Laughs in order to alleviate the high levels of tension in an otherwise rather grim and humourless episode of Sherlock (which is known - and loved - for its dry wit): John spends the entirety of A Scandal in Belgravia reveling in barely-concealed jealousy over how much attention Sherlock awards Irene, to the point where his Girl of the Week breaks up with him for being a better boyfriend to Sherlock than he is to her. John becomes completely incensed after the first time Irene fakes her own death, threatening her in an attempt to convince her to tell Sherlock that she's still alive. This doesn't stop him from feeling sorry about her apparent death at the end of the episode. Sherlock himself suffers from the Green-Eyed Monster whenever something other than the case they're working on distracts John.
In playing a conceited version of himself in Extras, Orlando Bloom seethes with jealousy over Johnny Depp:
The quote at the top of this page is provided by the amusing song "Jimmy Olsen's Blues" by the Spin Doctors from the early 1990's and featured the Daily Planet's favorite cub photographer lusting after Lois Lane and jealously grumbling about Superman. The song, despite being a catchy Ear Worm and a minor hit, actually didn't reflect the situation in the comics, where Jimmy didn't actually have any romantic interest in Lois and was famously known as "Superman's Pal, Jimmy Olsen." That being said, the song got Jimmy's name back into the pop culture mainstream, and for a while comic book artists actually drew Jimmy wearing a Spin Doctors t-shirt as a Shout-Out. Also, more than a decade and a half later in Superman: Birthright, the author added the detail of Jimmy having a bit of a crush on Lois.
This trope most often turns up in the case of love songs written for someone who is, well, already taken. Examples include:
The Seven Deadly Sins series by Vocaloid producer Akuno P aka Mothy. Envy's song is Tailor Shop on Enbizaka by Luka Megurine. She's shown to be a hard working tailor, constantly thinking about her "lovely person". This gets more twisted as the song goes on.
"Jessie's Girl" by Rick Springfield probably deserves mention here.
Cher Lloyd's "Want U Back" is about a girl who thought she was too good for her boyfriend and dumps him. Expecting him to be heartbroken, she's the one in the dumps when he bounces back and gets a new girlfriend. It is not a Green-Eyed Epiphany, she's jealous because the guy doesn't need her anymore.
Patty Loveless' "Jealous Bone" is about a woman who can't handle the thought of the one she loves with anyone else.
While the chorus of Lee Ann Womack's "I'll Think of a Reason Later" tries to paint what the narrator's feeling as Irrational Hatred, it's pretty obvious that the reason the narrator hates the new lady in the life of the man she loved is this trope through and through — she even mentions "having the slightest of a jealous bone" that tends to get larger when she sees him with her.
Mythology and Religion
Aphrodite, Eros' mother, because she was jealous of the beautiful Psyche, asked Eros to shoot her with an arrow so that she would fall in love with someone repulsive at first sight, but Eros ended up falling in Love at First Sight with Psyche. And then Psyche's sisters persuaded her to peek at Cupid because they were jealous of her gorgeous home.
Hera, Zeus' wife, was jealous of all of his numerous conquests. Hence why anyone that slept with or had any romantic contact with Zeus (including the ones he raped) would suffer horrible deaths at her hand. It doesn't exactly help that she's the Goddess of Marriage and Family, as well. It also doesn't help that he would shag virtually anything with legs.
Cain couldn't stand the fact that his brother Abel's sacrifices were accepted by God and his weren't, leading him to commit the first murder. Since God accepted the blood offering his brother gave of a new lamb and rejected his crops (and hadn't got around to saying murder was bad yet), Cain may have just been confused. The story doesn't really give Cain or God clear reasons for their actions. One common interpretation is that Cain gave grudgingly while Abel gave willingly.
In Flash Gordon, Dale's attempt to vamp the king of the hawkmen into sparing Flash backfires when his jealous favorite pushes her from the tower.
In Old Harry's Game, this really seems to be Satan's preeminent sin. At least Once per Episode, to the point of Catchphrase, the Professor alleges that Satan hates and corrupts various aspects of human life because, "You're just jealous." This accusation is born out by the fact that Satan is clearly very self-loathing. Also interesting is that while Satan's Fall was mostly God just being a dick, it's indicated that he wanted to be top Angel and was jealous of any others being put above him. Finally, we're told (since it's a radio show) that Satan has green eyes.
The page pic and caption about the Green Eyed Monster come from William Shakespeare's Othello, also the Trope Namer. The tragedy of the play comes about because of misplaced jealousy on the part of the title character because of a horrible lie about his wife Desdemona told by Manipulative Bastard Iago, who many say was himself motivated by envy toward Cassio, who Othello promoted instead of him.
Parsee is allegedly a bridge princess, mentioned above.
While this is Fanon only, Sakuya Izayoi has been leering to this after so many times not included as a main character in Touhou games, directing her jealousy at Sanae Kotiya (playable in Unidentified Fantastic Object) and Youmu Konpaku (returns in Ten Desires). Also, according to fanon, she has A-Cup Angst as well, which is why it is joked that any mention of the word "pad" will most likely get you knifed.
In Tales of Symphonia, the Pope apparently hates half-elves simply for their long lifespans. Ironically, some half-elves hate their long lifespans, because it means that while their non half-elf friends/comrades/lovers die, they'll still be alive, leaving them alone. Genis is initially troubled by this realization, but Regal reminds him that his friends can live on in his memories, comforting him slightly.
In Haunting Ground, the maid, Daniella, was created to be the perfect woman. But then Fiona is brought to the castle. Daniella is jealous of her because of the "attention" Riccardo gives to her. Fiona is "complete" and has the azoth (which is probably the womb and the ability to give birth). So she grabs a piece of glass and hunts Fiona, thinking that killing the girl will make her the most beautiful again, or she actually rips Fiona's womb out, as heard in the game over screen.
Jewel the Thief of Overlord is the Fallen Hero of envy who desires only what other people have.
One community adjustment to the Neverwinter Nights 2 official and Mask of the Betrayer campaigns has a line of dialogue in which a female PC asks Gann if he remembers all of the random farmgirls he seduced; and his response is "Is the green-eyed monster chewing on your toes?"
Depending on your PC's gender, this will exist between either Elanne and Neeshka or between Casavir and Bishop in the original campaign. To sum it up, Elanee stalks you and doesn't like you spending time with Neeshka, Neeshka gets upset whenever you agree with another girl instead of her, Casavir feels 'threatened' by Bishop, and Bishop despises you having a relationship with Casavir at all, even if it's not romantic.
Turns out this was the real underlying problem for Sakura in Fate/stay night. Actually, it was really obvious considering about 3/4 of the scenes involving her and quite a few about Tohsaka were exacerbating the problem, but the buildup had always been about Zouken Matou.
No, the real problem was Zouken. Not only was he responsible for putting the worms into her (without which she wouldn't have had the connection to Angra Mainyu), he was also responsible for activating her jealousy (and fear of what Rin might do to Shirou) in the first place. He was also (initially, at least) controlling the shadow, which did most of the damage. Her jealousy was the trigger for the connection to Angra Mainyu, and the darkness from the connection (together with Rin's apparent lack of care, and Shirou's total obliviousness) fuelled her jealousy, in turn making her connection stronger. But, without the worms there to make the initial link, and without Zouken to plant the seed, she'd have been perfectly fine.
Also Shinji to Shirou and Sakura for their ability to use magic, though this leans more toward Driven by Envy.
In Luminous Arc 2, Steiner's displeasure over Roland becoming the Rune Knight (with the Runic Engine he develops!) is the basis for his Heel-Face Turn and fuel to make the improved Runic Engine for him and his Stinger Squad. They do get get strong, at the risk of their body crystalising.
In Fatima's Route, Althea's jealousy over the closeness between Roland and Fatima, combined with the taint from the Conclusion Gate, creates and unleashed her Superpowered Evil Side.
Kain in Final Fantasy IV is easily brainwashed into betraying his friend and ally Cecil due to their shared love for Rosa, who chooses Cecil over Kain.
In BlazBlue, This is the eventual fate of Tsubaki Yayoi after being Trolled with some horrible truth from Terumi. See, she likes Jin Kisaragi, and originally she was to be Jin's secretary. Terumi then reveals that due to the existence of her best friend Noel Vermillion, she never became Jin's secretary (Noel got that position instead) and was instead relegated to a squad no one likes. Since Terumi told her that during the worst timing possible (Tsubaki was slowly going blind due to usage of Izayoi) and convinced her that she wouldn't suffer like this if Noel didn't exist... Tsubaki gave in to evil and continued to serve NOL despite knowing that it's an evil organization... all for killing Noel. Best part is that the guy she loves so much isn't even siding with the NOL anymore. Not to mention the fact that in the other timeline, she would've died anyway...
It gets worse, alright. In said timeline, Tsubaki was kept to her desk job and not allowed to leave headquarters. When Jin Kisaragi headed out to Kagutsuchi in pursuit of Ragna the Bloodedge, she was desperate enough to move over to the Zero Squadron - the aforementioned squad nobody likes - all for the sake of bringing Jin back. So in that timeline, she still died in the Zero Squadron, suffering in that fashion for Jin's sake, just like in this timeline. Terumi is aware that spilling this truth to Tsubaki would compromise his plans for her and Hakumen, and refuses to do so. He is also aware that Makoto Nanaya, the third wheel in Tsubaki and Noel's relationship, also knows, and is willing to take extreme measures to keep her lips shut.
In Rachel's Normal Ending, she trolls Terumi by claiming that he envies Ragna; for all of Ragna's flaws he is still a better and more interesting man than Terumi.
Terumi responds by kicking her teeth in. Interpret that as you will.
Rachel herself is envious of girls who get to hang out with Ragna in casual settings. She isn't happy to see Ragna eating with Platinum (the Joke Ending that follows should she decide to confront him confirms her feelings of jealousy). In episode 5 of "Teach Me Miss Litchi Reloaded", she agrees to teach Taokaka just to keep Taokaka from having dinner with Ragna.
In flashback, we learn that this was what prompted Don Paolo's rivalry with Professor Layton: jealousy over Layton's relationship with Claire.
Also, in Professor Layton and the Diabolical Box, Anton duels with Layton over his granddaughter Katia, thinking that she's his late wife, Sophia, and that Layton is trying to keep her from him for his own.
The reason why Yanagi stole Hiroki's painting in Canvas 2, which is apparently rather out of character for him.
In Monster Rancher 4, Phayne eventually discovers that his friend Wit is insanely jealous of him, and that this is what drove him to increasingly risky measures to prove he was the better trainer.
In Tekken, Heihachi favours his adopted son Lee over his biological son Kazuya which causes them to have a bitter rivalry. However, Lee eventually turns his back on Heihachi partly because of the way Heihachi has abused Kazuya (namely, throwing him into a volcano).
In AdventureQuest Worlds, Artix becomes this at the end of the ending cutscene of the second birthday event because he can't believe he missed the battle with Undead Artix.
Artix:Greetings and saluUUWHAT!... Un. Dead. Artix? And you did not take me to fight him? I want to fight Undead Artix!!!!! (kneels down in a defeated manner) I am so jealous of you!!!!!!!
Liquid of Metal Gear Solid is an interesting case. His envy of Snake for his having the dominant genes (however that was supposed to work) is peripheral to his real envy of Snake: that he got to kill Big Boss and in doing so deprived Liquid of what he believed to be his one way of validating his worth.
In the Fallout: New Vegas DLC Dead Money, Dean Domino was envious of the happiness that Fredrick Sinclair, founder of the Sierra Madre, had. Because of this, he planned to rob his vault in an attempt to break his spirit. Even after the bombs fell and everyone else was either dead or turned into one of the Ghost People he still remained as a Ghoul, plotting his heist. In the end, he doesn't succeed, since he ends up either killed by the Courier or decides to help him/her into the vault instead, later going through a Heel Realization in the epilogue and decide to let go.
In the Captivate 2011 trailer for Dead Rising 2: Off the Record, Frank West sounds quite jealous of Chuck Greene as he explains that he was the one that received the credit and fame for breaking the Fortune City story instead of him.
In Solatorobo, Elh gets a case of jealousy during the Prairie Kingdom Cup when Red gets too much attention from Princess Theria, Alicia, and Toffee.
Lt. Carter Blake in Heavy Rain towards Norman Jayden, his temporary partner from the FBI, particularly in regards to the ARI. Many of Blake's comments towards Jayden are equal parts disdain and envy; he has no respect for Jayden's strict adherence to procedure, but is shown to have some interest in the ARI. Particularly evident in one of Jayden's epilogues, in which Blake decides to try out the recently-deceased Jayden's ARI. It doesn't go well.
Whenever Talia Al Ghul is brought up in conversation with Oracle in Batman: Arkham City, she can barely contain the bile in her voice, given that both woman appear to have (possibly) shared a romantic relationship with Batman at some point.
Knuckles The Echidna from the Sonic the Hedgehog series is said to be envious of Sonic's freedom and popularity while his duty is to stay in Angel Island guarding the Master Emerald for the rest of his life. This may be one of the reasons for his hostility towards the hedgehog and why both have a rocky relationship.
Tales of Graces: Cheria admits to Sophie that she was jealous of her for getting most of Asbel's attention.
Miou in A Profile is extremely jealous of Masayuki's stepsister Rizu after Masayuki broke up with her to repair his relationship with said sister. How she reacts varies by route, but the story goes out of its way to show that she does have a point due to the circumstances involved.
School Days: Sekai and Kotonoha. VERY jealous of each other because they both like Makoto. The most infamous endings (as well as the one for the anime adaptation) have things ending very, very badly as a result.
In one of the bad endings for Bionic Heart, the main character's new android love interest murders his ex-girlfriend when she becomes jealous of all of the time that the protagonist spends with his ex.
In No Rest for the Wicked, Beast interprets Perrault's comments about "Beauty" to mean the girl, and that she left him for Perrault. He attacks him in a rage.
Subverted by Ginger from Collar 6, who sports green color scheme and is introduced as a possible contender to Laura for Mistress Sixx's affection. However, it is later revealed that while she is, indeed, in love with her "Madame", her feelings towards Laura are less of a jealousy and more of a disgust about her taking Michelle's love (something that Ginger was never able to attain) for granted. Eventually, the settle for a happy, trouble-free OT 3.
Wapsi Square: Monica accuses Bud of being envious of Tina. Bud has a bit of a problem with this seeing as she is also a bit envious of Monica and her relationship with Kevin.
In Kevin & Kell, Vin's hatred for Rudy stems from his belief, formed from working as an intern at Herd Thinners, that Rudy has everything he doesn't. He also becomes quite resentful at the end of the Y2k arc when Fenton and Ray reunite with their girlfriends.
Pibgorn Dru's fatal flaw — alas, usually someone else is the fatality.
Orphaner Dualscar of Homestuck was intensely jealous of Mindfang's romantic liaisons with other trolls - to the point that he murdered her latest conquest The Dolorosa and sold out Mindfang to the Subjugglators, dooming himself in the process.
Bittersweet Candy Bowl has Paulo jealous of his girlfriend's extracurricular activities keeping her away from him, and Daisy jealous of Lucy's success with guys, even though she blows them all off while they all ignore Daisy.
Tiffany in Eerie Cuties and Magick Chicks usually is one of the most nice and helpful (if a bit crazy) people around and the obvious crush on her "archenemy" Layla looked rather cute and innocent, but then... On a double-date first Layla was all over Kade, so Tiffany tried to poison him with garlic (she thought they both are vampires) and when this failed, stake him. After a misunderstanding caused by her hopelessly botched attempt Layla proclaims Kade ex-boyfriend and turns to Dio, and Tiffany immediately contemplates staking him first.
In Urban Underbrush, Clive and Blair's ex-girlfriend foment this at a nightclub. Alas, Clive is actually attracted, tries to kiss her, and gets a brush-off that reveals the truth to Blair.
In one Mario animated video online called "The Color of Envy", Luigi, jealous of Princess Toadstool favoring Mario, frees Wario from the dungeon, kills all the guards who oppose him, and throws Mario in the dungeon.
Dr. Horrible's envy of Captain Hammer fuels everything he does. It starts out with perpetual envy and disgust of Hammer's success and the (arguably undeserved) worship the city gives him, but what really drives him over the edge is envy/jealousy over Hammer dating the girl he's had his eye on, and Hammer gloating about it to rub it in his face, to boot. It doesn't end well. At all.
Part of why The Nostalgia Critic's a Bad Boss. Reviewing is the only thing he has so he's freaked out by people going into his territory and doing it better than him (or so he thinks).
The Nostalgia Chick and Obscurus Lupa are friendly at first (or as friendly as the Chick can be), but when Chick discovers Lupa has Todd's affections but doesn't want them, she's so jealous that she tries to kill the redhead.
Rarity also suffers from this when Fluttershy becomes a famous model. In an interesting handling of this trope, Rarity is actually very disappointed in herself for being jealous of her friend's success.
Spike gets this towards Owlowiscious.
Everyone thought Twilight was this in the second season finale, "A Canterlot Wedding" thus causing them to nearly disown her. If she wasn't Right for the Wrong Reasons that is.
Jem is loaded with this. The Misfits want to destroy the Holograms because they're jealous of their success, Eric Raymond wants to destroy Jerrica Benton because he's jealous of her ability to run a music company better than him, and Jerrica is actually jealous of her own alter-ego because of of the attention Jem receives that Jerrica can't get for her own accomplishments.
Alexandra's reason for wanting to be the lead singer of Josie And The Pussy Cats was jealousy of Josie, and the fact that Alan paid her no attention.
An episode of Tiny Toon Adventures had this as its Aesop, but the characters don't realize that the warning about a Green-Eyed Monster isn't talking about a literal monster until the very end.
The two main characters in Kim Possible encounter this in the third season and The Movie, due to a Romantic False Lead and a new friend with a kickass wheelchair and video games. There was also Kim "jelling" over how close Yori seemed to Ron. It's kind of a coincidence considering Kim really does have green eyes.
Kim gets jealous over Ron at almost the drop of a hat: she also gets jealous when he becomes good friends with Felix in "Steal Wheels," and gets very angry over the time he and Bonnie spend together in "Homecoming Upset" - a lot more justified that time, however, as they were dating at that point and Bonnie was doing everything in her power to run it in. To her credit, she manages to direct almost all her anger at Bonnie and not Ron.
"What You Want" showed Tucker envious of Danny's ghost powers. It's a kick in the teeth to him especially because Danny was once on equal terms with him before he got his powers, making him (in Tucker's perspective) more "superior".
Code Lyoko has Sissi Delmas who loves Ulrich and is jealous of the relationship between Yumi and Ulrich — so she tries to make Yumi jealous in turn (sometimes successfully). Also, when William Dunbar enters the scene in Season 2, Ulrich shows serious envy of William's easy flirting with Yumi, while he himself Cannot Spit It Out.
In "Date With Destiny'', Starfire becomes something of a Yandere once she finds out that Robin is taking a bratty Daddy's Girl to her prom.
Robin also becomes rather green-eyed over Starfire when she's getting married in "Betrothed". Cyborg explicitly teases the boy about it, saying, "You sure you're not just, y'know... jealous?"
Princess of The Powerpuff Girls became a supervillain because she was envious of the Powerpuff Girls ("If I can't be a Powerpuff Girl, then there won't be any Powerpuff Girls!"). In "Superfriends", she becomes jealous of Robyn, who has become the Girls' best friend, the only thing theSpoiled Brat has ever wanted but could never have. ("Why would the Powerpuff Girls want to hang out with you when they could be friends with me?!!...")
An episode of Disney's Hercules (called, appropiately enough, "Hercules and the Green-Eyed Monster") has Icarus being jealous that his drama teacher is marrying his father, and thus getting most of his attention, and disrupting the wedding with Pandora's box. He is then consumed by Jealousy, as in swallowed whole by an Anthropomorphic Personification who has been feeding on his envy.
Thrust, one of Starscream's clones in Transformers Animated, embodies his creator's envy. This is appropriate, as he's the only clone who doesn't appear in the cartoon or the toyline - he only showed up for the second Allspark Almanac.

In the interquel comic series of Avatar: The Last Airbender called The Promise, Katara shows a mild case of this. She feels a bit upset that Aang hangs out with the Air Nomad fan club more than her, making her feel left out. But this is resolved (somewhat) when Aang explains that the fan club reminds him of his old home. That, and he loves her.
She's shown a bigger case of this in The Waterbending Scroll, though. This is due to not getting Waterbending right instantly while Aang, being an Airbending Avatar, did. This causes her to yell at him about it only to feel guilty and apologize, and she also put the others in danger due to stealing a pirate's scroll. She gets over all this, though.

Korra also suggests that Unalaq's desire to train her stems from his envy of the fact that Tonraq sired the Avatar.
Ben 10 has multiple exemples of this. Considering the protagonists gains Famed in Story starting with the third installment of the show, that's kinda understandable:
Captain Nemesis, despite being himself a famous superhero as well as possessing his own company, developped a jealousy when Ben starts becoming more popular than him (ironically, Ben himself admired him then). He first attempted to get back credit in a so-called friendly competition with him, but ends up humiliated (the only round he is able to win is only thanks to part him cheating and part Ben's Omnitrix malfunctionning). Unable to stand this, he turns evil as a result. By his second appearance, he has gone as far as becoming a murderer.
A more light-hearted exemple than the two previous ones, minor villain Billy Billion from Omniverse has his whole motivation running around the fact he was jealous of Ben for getting more attention at school than him.
Prince Tritannus in Winx Club is jealous of his twin brother's popularity and lock on the throne. As such, he attempts to assassinate Nereus. When this fails, he retaliates by trying to conquer the whole Magic Dimension, brainwashing Nereus in the process.
