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.

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. Thomas, of course, being an amoral sociopath, doesn't grasp that Bruce's parents might be different from his parents, making this a rare case of someone consumed by insane jealousy not because of what someone else has done or accomplished, but literally for NO REASON AT ALL.
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.
