In A Certain Magical Index, Fiamma of the Right is powered up by the malice of his enemies. This is why he triggered World War III. He declared the world his enemy, and the malice the conflict would cause would power him up enough to wipe it out. He still loses in the end, as the human race is ultimately not as evil as he thought.
Black Butler. Earl Phantomhive is driven by hatred and anger, not to mention the need for revenge. It is this quality that allows him to command his invincible Battle Butler, Sebastian - and, most impressively, shrug off a Lotus-Eater Machine later in the series. An angel attempted to 'revise' his past, showing him his now-dead parents welcoming him back with open arms, telling him to let go of his hatred and just join them in love and happiness. He refuses, turning his back on them to continue pursuing vengeance for both their fates and his own, thus allowing him to escape with his memories and sanity intact.
In Claymore, Dae believes the Claymores' power is dependent on the hate they feel towards the yoma flesh implanted in their bodies. That's why the Organization preferred to use children who had suffered extreme yoma-related trauma, to the point that they would create such situations if necessary, for their Claymore experiments. Dae also believes that this is why Priscilla is practically a Physical God. When she killed her yoma-mutated dad, she somehow knew it really was her father and not a shapeshifting monster. She repressed the memories, but the lingering self-loathing was so strong that it made her the most powerful Awakened Being ever.
In Digimon Adventure, it's explained that the only reason Gatomon was able to survive the years of abuse she suffered under Myotismon was by clinging to her hatred of him. What's more, the only logical explanation why Myotismon has been able to return from the dead three times must be his hatred toward the Digidestined.
It seems to go par with the course, for you need to be overwhelmed by negative emotions in order to first transform.
In Katekyo Hitman Reborn!, the Vindice are former Arcobaleno that have had their Pacifiers taken away, and with them their Flames. While most die from this, some draw enough willpower from hate to keep living, replacing their lost flames with the eight Flame, the Flame of Night.
In Kurohime, hate is a literal power source. The resident Angel holds on to her power and sanity by clinging to her hate of Kurohime. The eponymous heroine is powered by hate: she crystallizes the anger of the ghosts of all of the people she's killed (in her quest to kill the gods) into a power source known as the Black God Tree. And, yes, it's pretty powerful.
In the Monster Rancheranime, Big Bad Moo draws power from others' hatred. After revealing this to the Searchers, he then takes advantage of it by torturing Pixie in front of them. This backfires when the sheer force of their hatred drives him insane.
Princess Mononoke is full of this. Hatred is so powerful that it infuses itself onto the Prince Ashitaka's arm and gradually consumes him to death. It is also what turns the merciful boar god Okkoto into a demon both by the hatred manifested by humans in a man-made bullet and ultimately Okkoto's own refusal to come to peace with the conflict.
Lucia has a bone to pick with the whole planet in Rave Master. Even though his main goal is to get to the original world, he's willing to take the chance he gets to destroy the world everyone lives in first. For bonus points, the final form of his sword is powered by his hatred.
In Unico In The Island Of Magic, the main antagonist Lord Kuruku is made of this trope and manages to play it straight to an almost scary level. He used to be a puppet who was abused and eventually thrown away by the children who owned him. After awhile, he became animate and became an evil sorcerer who would turn humans into puppets. Eventually, once all his hate is removed, he turns back into a lifeless child's toy as it was the only thing keeping him alive.
Zatch Bell!: The counterpart of Tia's spell Saifojio, which is a healing sword fueled by friendship, is Chajiru Saifodon, a sword that grows stronger and scarier by feeding off Tia's anger and hate. What caused her to discover this spell for the first time? A mamodo who kept flipping her skirt to see her panties.
The G7 iteration of The Authority ran up against a bunch of reality-altering supervillains who tried to turn them into the real Authority. Their enemy's plot fell apart because the thoroughly-homophobic Last Call refused to become the openly-gay Midnighter.
Colonel: Congratulations, mate. Your homophobia saved the world.
Batman. In some of his incarnations, the hate for the villain that killed his parents drives him to be the Batman. (Other incarnations are more about justice, or protecting people.)
You could also say that he feels nothing but hate for the Joker. And after all the Joker put him through, you can't really blame him.
It could be argued that Batman hates hates HATES the murder (and violent crime in general) and injustice of the world itself and is therefore driven to don the cowl to exterminate these things or end up showing the world he died trying.
The Joker himself, after being brain dead for years in The Dark Knight Returns, snaps out of it when he hears of Batman's return.
Shortly after Brand New DayJ. Jonah Jameson's stress started severely threatening his health. After being hospitalized once for this, he tried several relaxation techniques to help him, until he discovered one that worked: Whenever the stress would start to get to him he repeated to himself "I will not die before Spider-Man."
Doctor Doom. His never-ending, all-consuming, obsessive hatred of Reed Richards is what gave him the drive to become Marvel's most iconic supervillain of all time.
As Dracula recounts his imprisonment in Sultan Murad's dungeons in Dracula Lives, he notes that while his more "feeble-minded" brother Radu couldn't survive in those conditions, his own hate kept him alive through the ordeal.
The Red Lantern Corps is fueled by hatred and rage, specifically hatred and rage driven by personal loss of someone emotionally close to them.
Atrocitus: Do you hate? The most powerful hate is not born out of ignorance or prejudice or a perceived threat. Those three are fear in disguise. The fury that fuels my corps ignites from personal pain. Those whose lives were ravaged by greed, lust and control wield the crimson light. The rings replaced our damaged hearts. They beat for them. And they keep us alive only to hate. But at least we live.
Atrocitus hates the Guardians of the Universe, since their Manhunters destroyed his family. He became so blinded by rage that he murdered four of his friends and became the first Red Lantern.
Bleeze was raped by a group of men for being condescending, and had her wings cut off. Her hatred for them made her a Red Lantern.
Dex-Starr led a happy life with his owner, before she died and a group of children tried to kill him.
Rankorr suppressed his rage all his life, but let it out when his brother was beaten to death by the police.
Supergirl finally had enough of being pushed around by everyone, from H'El to her roommate (which was actually Kara's fault to begin with), and just stopped caring and let it all out.
Iron Man foes are a varied bunch, but they are all driven by their burning hatred of Tony Stark. The Mandarin Rings in particular are programmed to do nothing but make Tony Stark suffer and choose people who either already hate Tony or could be goaded into hating Tony.
Despero, a foe of the Justice League and of the Martian Manhunter, is driven by unadulterated rage - tempered by a certain amount of cold cunning and pure hatred. Martian Manhunter once defeated him by using his mental powers to make Despero hallucinate killing all the heroes, at which point he declared he was satisfied and let go of all his hate and anger, regressing to a baby. Unfortunately, when he found out he had been tricked, his hate and anger came back and he returned to normal.
In the famous Legion of Super-Heroes "Great Darkness Saga," the restored clone of Orion says to Darkseid "I live father... and live to hate!" Subverted in that Darkseid proceeds to destroy him.
At his worst, Lex Luthor is driven purely by his Irrational Hatred of Superman. The idea of dying before Superman does sickens Lex to the point that he will force himself to cheat death.
It is made clear that Magneto focuses his power through hatred of those who'd persecute his people (Jews and Mutants).
The Saint of Killers from Preacher used his hatred to survive the torture of Hell and freeze it over, eventually letting Satan release him so he could continue acting on his hatred in the name of God.
When Gallows jumps after a jetpack-wearing mook in The Punisher 2099, he brushes aside the fact he doesn't have one himself:
"I don't need a jetpack— all I need is hate!"
The Red Skull became one of the Marvel Universe's most horrible and dreaded supervillains thanks to his burning hatred of everything. Nazism just gave him a focus for the anger and resentment he felt towards life. It even carries him beyond death as seen in Marvel Zombies. When all other zombified heroes and villains are driven only by their mad hunger, Red Skull is still driven by his hate, to the point where killing Captain America by tearing out his brains moments before being vaporized prompts him to remark "It was worth it. All of it. Just for this."
Honda's Grrr advert, featuring a cheery song about how hating something makes you change it to something better.
In Earth and Sky, Diamond Tiara is abducted by Changelings and left to die in the badlands after they kick her out of their hive because she is too unpleasanteven for them. At first she is overwhelmed with despair and sinks to the ground ready to die. Only the thought that dying would mean Applebloom, whom she has hated her entire life starting from their first meeting in a playpen, "wins" by default keeps her from giving up. She perseveres through the badlands and reaches civilization, running on nothing but pure hatred. She doesn't take it well when she realizes that because her hatred for Applebloom kept her alive, she owes her life to Applebloom.
Vathara, author of Embers, noted once that both Hate and Love can drive people to acts of equal greatness or depravity, and allow them to survive seemingly insurmountable odds.
How does Twilight Sparkle defeat the Changeling Queen in Faith and Doubt? She channels "hate poison" into her, while everyone watches in horror. The fact that Queen Chrysalis is continuously shapeshifting into Twilight's friends and family doesn't help her in this situation.
Invoked in the Nazi-themed drama The Damned. After the sensitive student Gunther learns that his favorite aunt has died in a concentration camp through the machinations of his in-laws, SS leader Aschenbach pegs him as an ideal recruit: "You've made a most wonderful discovery. You possess hate! It's a new hate - pure, absolute."
The title curse of The Grudge is the result of someone dying in a state of extreme fear or anger. The same fate befalls some of the protagonists of the movies because of the fear of being killed.
A particularly effective tool in the Canadian film Nothing.
Inigo Montoya from The Princess Bride spent twenty years in search of his father's killer. The look on Inigo's face (courtesy of Mandy Patinkin) and the tone in his voice when he finally catches up with the man is something to behold. He even gives the man wounds that mirror those inflicted upon him, in order from newest to oldest. (Scene available at end of video here.)
Inigo: Offer me money. *face-slice* Rugen: Yes. Inigo: Power, too, promise me that. *face-slice* Rugen: All that I have and more! Please... Inigo: Offer me everything I ask for. Rugen: Anything you want. *Tries for a last-minute parry-and-chop, but--* Inigo: I want my father back, you son of a bitch.
"I am constantly amazed by the curative power of hatred."-Montrose, Rob Roy, commenting on Cunningham's swift recovery (regaining speech) after Rob gave him a throat wound.
Scarface (1983): It was hate, and the power of cocaine, that made Tony Montana so hard to kill in the endgame.
Emperor Palpatine, although most people remember the other half of the quote.
Darth Vader demonstrated a different take on this in a comic story that pitted him against a Darth Maul clone. The idea was that his remaining love for Padme meant he lacked the hatred necessary to call himself a Sith Lord. He won by letting Maul get behind him and stabbing himself through the stomach.
Maul (incredulous): What could you hate enough to destroy me? Vader:Myself.
After everything goes wrong for him in a rather big way, Tyrion Lannister seriously contemplates suicide and has nothing to live for, except to get revenge on ... well, everyone in Westeros, though his family tops the list.
LordVarys states that when his balls were cut off as a child by a sorcerer, he asked the man what he should do. "The man said he supposed I should die. To spite him I resolved to live." However, Varys is an unusual example because his hatred is not directed against any particular person (though he does claim to detest sorcery, for obvious reasons,) and he is one of the coldest and calmest characters in the books.
Doran Martell has put an extremely slow-growing plan for vengeance into action for well over a decade. Given that he is ridden with gout and in constant pain, one could easily argue that he might have let himself die before now if he didn't have his revenge to plan.
Wyman Manderly has a similar bone to pick with House Frey and House Bolton for the Red Wedding.
Sandor Clegane, the Hound, makes no secret of the fact that he wants to kill his brother Gregor, and many suspect that if the opportunity to do that was taken from him he'd have nothing left to live for. His aimless wanderings after Oberyn kills Gregor suggests they're right.
Catelyn Stark's hatred is all she has left as Lady Stoneheart.
A speech to the effect of "live and get revenge" is what motivates Jaime Lannister to not lie down and die after his sword hand is cut off.
Arya Stark, age nine, endures all kinds of horrible, traumatic experiences that would break most adults, plus an incredibly harsh training that involves, among other things, going blind, throwing away her identity and murdering people, just so she can kill the people who murdered her family (whose names she mutters every night like a prayer before sleeping).
The power of hate is explicitly said to be why Dumbledore is considered weaker (technically) than Voldemort. Voldemort, being fueled by hate, is willing to use evil magic like horcruxes or curses. Dumbledore doesn't because he's still sane enough to realize the cost of such power.
The first time Harry attempts an Unforgivable Curse against Bellatrix Lestrange, she brushes it off fairly quickly and tells him that righteous anger won't fuel an Unforgivable as well as genuine malice.
This is also what drove Sirius Black out of Azkaban. Dementors could take out happiness, but hate gave him direction while knowing that he was innocent kept him sane.
This is the main theme of the Malus Darkblade series. At several points in the series, the only thing motivating Malus to keep going is the thought of destroying his enemies.
Memory, Sorrow, and Thorn: A key component of the spell to summon the undead Storm King back into Osten Ard is the channeled fear and hate of all the mortals in the world, fomented by the very war that the Storm King started. Rejecting this hate is the key to defeating him.
In The Spy Who Haunted Me by Simon R. Green there's a minor character who is a goth with the power to hate things out of existence. She just stares at them, focuses on how much she hates, and they vanish forever.
In Perelandra, from CS Lewis's Space Trilogy, there's a moment when the hero Ransom is physically battling the evil Dr. Weston who just happens to be possessed by the Devil discovers not just a moment of Perfect Hate, but also just what to do with that hate, which allows him to actually overcome a far stronger enemy. Or to put it another way: knowingly, Yes He Did Just Punch Out Cthulhu.
In Angel after being trapped in the hell dimension Quar-toth Holtz attributes his ability to survive to this trope, before he started surviving through the Power of Love instead. His final actions make it pretty clear that he never gave up on the hatred.
In Babylon 5, the Narn are hugely motivated by their hatred of the Centauri. Londo even claims that if you got together all the Narn and got them to hate simultaneously, they would destroy Centauri Prime. The hatred is quite mutual.
Doctor Who: The Pratt/Beevers version of the Master (the one that looks like a corpse), was once quoted as saying that hate was the only thing keeping him alive.
You do not understand hatred as I understand it. Only hate keeps me alive. Why else should I endure this pain?
And from the New Series;
"What does hate look like, Amy?" "Hate?" "It looks like a Dalek."
In "Asylum of the Daleks", the Daleks are revealed to imprison, not destroy, those among their number who are deemed too insane, simply because they cannot bring themselves to remove such pure hatred from the universe. The Dalek Prime Minister suggests that is perhaps the real reason why they've never been able to finish off The Doctor.
In the Haven episode "Roots", trees start attacking people by extending their roots like tentacles. Audrey and Chris eventually realize that the trees are feeding off the hatred between the feuding Keegan and Novelli families (every time the families argue or fight, the roots grow faster and go berserk). When they manage to convince the families to make peace, the trees revert to normal.
In "Fear and Loathing", Tristram Carver made a puzzle board depicting Haven and filled it with his hate of the town. If a piece is fitted into the board, the corresponding area of Haven is vaporized. The puzzle continues to function centuries after his death.
Morgana in season three of Merlin is driven entirely by hate, some of it understandable (toward Uther and Merlin) and some of it inexplicable (the writers never give us a reason why she suddenly loathes Arthur and Guinevere).
In the series finale of Monk, Monk is poisoned by an employee of his wife's murderer. After learning the mastermind's identity, his condition improves.
Cpt. Stottlemeyer: How is our boy? Monk's Doctor: He's stable. Actually, he's better than stable. His vital signs have improved. We're not sure why. Cpt. Stottlemeyer: That'll be the hatred. Pure malice is the best medicine in the World.
In Kamen Rider Double, Shroud's original plan for Double was to team up Philip and Narumi to make use of Double Cyclone Accel Xtreme, which is powered by hatred rather than Cyclone Joker Xtreme, which is what was used in series. When he died, she tried to use Isaka, but he turned out to be a bit... Crazy, and then turned to Terui Ryu and planned to use his feelings of revenge to power CAX, which by the point it was revealed, the revenge plot was over. Either way, we never see it used in a fight in-series.
The Monster of the Week of one episode of Xena: Warrior Princess was a sorcerer who could drain all the goodness out of a person to feed himself, turning the victim to stone in the process. One character is immune to this, and he explains to Xena that he concentrated on negative emotions like hate, so the sorcerer couldn't feed on him. Xena does the same thing in order to fight the sorcerer.
Zyuden Sentai Kyoryuger has a villain who gets his power from hatred. Heck, it's even in his title: The Knight of Resentment.
Most beings in Exalted are only capable of so much hatred- literally, as the game puts a hard limit on the number of Intimacies you have (or, at least, can gain a mechanical benefit from). Kimbery, however, has no limit to the number of negative Intimacies she can possess, and can never forget a negative Intimacy... and the more negative Intimacies she has, the more powerful she becomes. Also counts for all Infernal Exalted that take her Charms.
Malfeas is also a strong contender for this trope- he is endlessly angry about the atrocities visited upon him by the Exalted, which manifests as an ability to ignore all pain, as well as an ability to burn his enemies with irradiated green fire. If you're lucky, he'll "only" kill you.
The Neverborn are dead Primordials who exist in constant physical and spiritual torment, unable to either fully cease existing or be reborn in new forms. Although unable to leave their world-sarcophagi, their resentment of the living world was great enough to create the Deathlords, and their Whispers constantly resound throughout the Underworld, driving ghosts mad and warping them into nephwracks.
Genius The Transgression gives us Clockstoppers. Whereas Geniuses are enraptured by the possibility of the world, Clockstoppers possess an anti-intellectualism so potent and vitriolic that it stops progress. Their powers involve raising angry mobs, breaking a Genius's Wonders through spite alone, and draining Mania just through endless anger.
In Magic: The Gathering, Hatred is a card. Also, "hate" refers to any card that destroys another strategy, such as Torpor Orb (which stops comes-into-play abilities) and allies (which are only activated by allies coming into play).
The High King of Dwarves invokes this by coming to battle equipped with the "Book of Grudges," a huge tome filled with all the transgressions other races have committed against the dwarves. He picks the entries relevant to the current enemy and reads them like a litany, making sure his retinue goes to battle with the proper attitude.
The "hatred" special rule gives units bonuses when fighting their hated enemy. Some units take things a step further and can re-roll attacks against a specific enemy, but only in the first round of combat with any given unit — after that, the hate's expended until you pick a new target. Certain units (like all Dark Elves, towards High Elves) have "Eternal Hatred" — such raw, unbridled loathing that they can re-roll attacks against their enemies every combat round.
In Asura's Wrath, Asura's endless, boundless, pure, absolute hatred of the people that betrayed him and who are destroying and exploiting the world around him are what gives him his seemingly impossible ability to keep on fighting and draw upon enough power to destroy entire fleets. In the climax of the DLC episodes, he fights Chakravartin, who is essentially God, and wins, while fighting on pure hatred.
The power of Asura's hatred is shown relatively early one while fighting Wyzen. He's just recovered from climbing back out of Naraka, and doesn't remember what happened to him or why he was there. He starts fighting Wyzen, and is able to hold his own, until Wyzen finally loses his patience and turns himself into his massive, planet-sized version, and then proceeds to crush Asura with his finger. Then, while being smashed by said finger, Asura remembers what they did to him...and why he hates them. Then the Unstoppable Rage begins, culminating in him punching Wyzen so hard that the blast wave travels up his entire arm and causes him to explode.
BlazBlue: Yuuki Terumi deliberately invokes this. It's the only way he can keep his spirit in the living world. However, this is not played to garner him sympathy, he also gets off on getting people to hate him and making them miserable.
The heroic version of this comes in the form of the Demon Hunters of Diablo III. They are primarily fueled by hatred for the demons, to which they have lost friends and family; but unlike the scions of Mephisto, this hatred is tempered with discipline instilled in them through the training that every Demon Hunter receives.
In Dragon Age: Origins, Keeper Zathrien cast a powerful Blood Magic fueled curse out of hate centuries ago, and hate is the reason he refuses to release it even though the original targets of his hate are long dead. If the player tries to convince him to let go, he will confess that he doesn't know if he can anymore. In his own words, the hatred has become a bitter gnarled root in his heart. If he does release the curse, he dies with a look of total peace and calm on his face.
In Final Fantasy IV, even after Zemus dies, his hate is so powerful that it is able to materialize, curb stomp the two who had just killed him, and become the Final Boss of the game.
After being defeated in Final Fantasy VII, Sephiroth was only able to maintain his sense of self in the Lifestream by focusing on his hatred of Cloud at the expense of everything else. As a result he is completely obsessed with taking revenge on Cloud in Advent Children.
In Final Fantasy XII, Tragic Villain Gabranth is fueled not just by his loyalty to Arcadia, but also his hatred towards his twin brother Basch, whom he believes fled their original homeland Landis, and their own mother, in an act of cowardice (its a bit more complicated then that). By the end of the game, after being given a brutal"The Reason You Suck" Speech by Cid about how he's only useful as Vayne's lapdog and isn't even worth that, Gabranth loses his loyalty to the Arcadians, leaving only his hated for Basch to motivate him towards anything.
Gabranth: SILENCE! ALL was stripped from me! Only the hatred for the brother that fled our homeland remains mine!
In Dissidia: Final Fantasy, the characters have no full memories when summoned to fight, only retaining the barest hint of memory and the emotions linked to them. Gabranth doesn't remember much about his life except for feelings of intense hatred, but he can't remember what it was directed towards. Thus, in his own words, "Hatred is what drives me!"
This is stated to be the reason Stringy-Haired Ghost Girl Alma is still around (along with her Psychic Powers) and boiling people into bloody skeletons in FEAR. Being left to drown by your own father in a sealed lab after being impregnated at a young age and having the children taken away will upset people like that.
Might and Magic: Heroes VI has the pit fiends, servants of the demonic overlord of Hate. Their powers include a retaliation attack that strikes any creature that has harmed them during the battle, hatred-inducing strikes that make their victims unable to distinguish friend from foe, and a powerful spell that incinerates all enemies.
The Unversed feed on negative emotions and are eventually revealed to be extensions of Vanitas's hatred. One noticeable, and infamous, example is the Cursed Coach, who was summoned from the Tremaine family's pure hatred of Cinderella, and sent to kill her after she was freed from their tyranny.
After Scar was killed by his own nephew Simba, it turned that his hatred was so strong that it not only bought him back immediately from the dead but it turned him to a Heartless as well, and yet he kept his original form. So far only Xehanort had been able to do that when he turned into a heartless, and usually only those individuals with a enormous set of darkness in their hearts and an extremely strong will can do that. Lampshaded by Pete of all people.
Sion in Knights of the Old Republic 2 is a corpse held together by the power of his own hate. If you convince him to let go of his hate, his consciousness falls apart.
In League of Legends, Urgot survived being cut in two by Garen and rebuilt into a powerful Magitek cyborg by Professor Pididly. All attempts to recreate the process ended in the death of the subject, and Pididly suggests that this is because his other subjects lacked Urgot's hatred for Garen.
It is explained in The Legend of Zelda: Skyward Sword that Ganon is the manifestation of the hatred of Demise. Demise curses the descendants of the first Link and Zelda to forever fight his incarnation of hatred.
If hatred was a metal and Mortal Kombat regular Scorpion was a blacksmith, then he most certainly forged a BFS out of it. A BFS that he promptly drove through Sub-Zero's heart.
In the original Mother, Giegue was forced to choose between loyalty to his species and his love for Mary, the human who raised him. He chose the former, but was ultimately beaten by Mary's son, who forced him to remember Mary's old lullaby. In the Earthbound future timeline, Giegue has traded in his old body for an intangible form of pure hatred.
The Pokémon attack Frustration deals more damage if the user dislikes its owner.
In Prototype 2, at the end of the second act, a pissed off Mercer attacks Heller for messing up his operations, and attempts to consume him to end the problem. When Mercer's consumption attempt causes the image of Heller returning to his home to find his wife dead and daughter missing, Heller gets so furious he actually burns off Alex's hands.
One of the basic powers in Psychonauts fires "Mean Little Balls of Hate" as projectiles, which represent Raz's will to do harm. When demonstrating, Sasha tells Raz to picture something so repulsive that it simply must die, such as a Tiffany lamp.
Clockwerk from Sly Cooper actually made himself immortal through, in his own words, "a steady diet of jealousy and hate." That, and making himself into a giant mechanicalowl. Powered by hate.
Literally. A major plot point of the second game endgame revolves around Clockwerk's recovered "Hate Chip", which roughly speaking empowers the Clockwerk's body through energy derived from hate. The Big Bad's ultimate goal is to hijack Clockwerk's reconstituted body and throw a major metropolis into a drug fueled Hate Plague in order to grant themselves ultimate power and immortality. It's worth realizing that, while they needed to go to these lengths themselves, Clockwerk was able to power his body entirely through his own hatred. Later, once the chip is destroyed, the other parts of Clockwerk's still pristine body immediately disintegrate, implying that they were kept together entirely through Clockwerk's residual hate. Now that's a lot of hate.
As established in previous Star Wars related works, the Sith in Star Wars: The Old Republic run on this trope. The Sith Warrior regains health with an ability called "Channel Hatred", and the Sith Inquisitor does so with one called "Seethe."
Used unusually in Sonic and the Secret Rings: during the true final boss fight, Erazor Djinn absorbs the powers of the seven World Rings in order to transform into Alf-Layla-Wa-Layla. However, Sonic's emotions caused by Shahra's death cause the world rings of rage, sadness and hatred to be ripped out of Al-Layla-Wa-Layla's body and be absorbed by Sonic, turning him into Darkspine Sonic. This means that it's the hero who is powered by negative emotions, while the villain is the one harnessing the positive emotions.
The Suul'ka from Sword of the Stars were nearly annihilated by the Liir and their ultimate weapon The Black another Liir Elder using the same battle armor as the Suul'ka who exists solely to destroy them. The survivors fled into the depths of space and slept, seething in hatred all the while.
We slept. And healed. And hated.
In the roguelike Tales of Maj'Eyal, some classes actually use hate as a resource for using their abilities. It decays over time, but is built up by encountering a new enemy, taking damage, and killing enemies, among other things.
In Tales of Maj'Eyal the Afflicted classes use hate as the resource that fuels their abilities. It goes down over time, and is replenished when you hurt or kill things, are badly hurt, and so on...
Valkyrie Profile: Covenant of the Plume gives us Wylfred, who hates the Valkyrie for claiming his father as one of the Einherjar, causing his sister to die from hunger and his mother to go insane. This hatred is so raw it intrigues Hel of Nifelheim. The game's ending depends on how far Wylfred is willing to go for hate.
Lieselotte, a character Wylfred can meet, runs heavily on the power of hate. In her backstory, she was adopted by a court magus, Cennair, who taught her to read and write, and Lieselotte became a court magician. However, Cennair was killed due to an errant spell, and Lieselotte and another court magician, Rosea, were suspected of murdering him. As Lieselotte knew that she was innocent, she reasoned Rosea had to be guilty, but Rosea claimed Lieselotte was the killer. Both girls were exiled. The trope becomes deconstructed when Lieselotte and Rosea meet again, and Lieselotte acknowledges that all hatred did was leave her lonely and alone, with nothing but herself to hate.
Street Fighter's M. Bison draws upon a power called "Psycho Power", which is both this and Made of Evil. It condenses negative thoughts (hate, among them, but also things like fear, anguish, pain, and despair) and channels them into power. His soul embodies this while the good part of him splintered off and became Rose, along with its positive equivalent "Soul Power".
Dragon Ball Multiverse: This seems to be Raichi's specialty. He claims to be able to channel the hatred left behind when someone dies a violent death, using it to adopt the deceased's essence and create a ghost, with the deceased's might and powers, as well as some degree of personality.
Every member of Kyran's race in Emergency Exit is fueled by some emotion or another. His is hate.
Part of Zola's invincibility in Girl Genius comes from this, keeping her standing long after she should have gone down. The other part of her invincibility comes from drugs. Drugs which should have caused her system to go into overdrive and self-destruct, except that, you guessed it, the power of hatred let her use that energy instead.
In Gunnerkrigg Court, Jeanne has been shaped by her lover's murder, her own slow death, and her subsequent imprisonment by the Annan Waters into a spirit of rage and hatred powerful enough that Word of God states that she could give Coyote problems.
4chan's /v/. Demonstrated by the now infamous fight da power video.
Another Cracked article argues that people are eager to categorize others as 'monsters' because humanity as a species craves the power of hate.
littleKuriboh's NGE Oneshot. The Angel is wiping the floor with Shinji, so what does Gendo (inexplicably yet perfectly voiced by Charles Montgomery Burns) tell him? "You have have to pretend it's me." Cue Curb-Stomp Battle set to "Ode to Joy".
Played for Laughs in Archer, where Carol comments that while she hates everyone at ISIS, she spends time with them because the hatred is the only thing getting her out of bed in the morning.
In Avatar: The Last Airbender, after Zuko completes his Heel-Face Turn, he loses most of his firepower, since he no longer has his burning anger to fuel his flames. In fact, firebending in general seems to lean toward this, at least the bastardized version that's been promoted since the start of the hundred-year-war. True firebending doesn't need hate, as Aang and Zuko learn from the Sun Warriors.
In one time traveling episode of Captain Planet and the Planeteers, Captain Planet comes face to face with Adolf Hitler himself and nearly passes out from the sheer hatred eminating from the man. (Captain Planet's kryptonite is anything toxic, and one of his components is Heart, so...)
In The Simpsons it has been revealed that hate is what keeps Monty Burns alive.
The Smurfs: Chlorhydris, the personification of hate in the Smurfs' universe. Many of her schemes involve spells meant to destroy love and replace it with hate and evil, but the Smurfs always find a way to defeat her.
In a Super Secret Secret Squirrel cartoon, Secret counteracts the effects of Queen Bee's Love Potion by focusing on his hatred of crime (or more likely just hate in general).
In Teenage Mutant Ninja Turtles (2012), Tiger Claw claims that only his hatred and desire for revenge against the turtles, Splinter, and their human allies allowed him to survive his trek home after being swallowed alive by giant alien worm and then stranded in another dimension.

Bismarck, the Prussian Chancellor responsible for the unification of Germany, is a good historical example. The man relied on people hating him as a source of motivation during times of difficulty. Take the following quote from Robert K Massie's Dreadnought:
Lying in bed, he mulled over grievances. “I have spent the whole night hating”, he said once. When no immediate object of hatred was available, he ransacked his memory to dredge up wrongs done to him years before.
Vladimir Lenin was similar, perhaps even moreso than Stalin. While Stalin was also driven by paranoia, fear, and ambition as well as by hatred and ideology, Lenin was driven mostly by a singleminded combination of the latter two, almost to the exclusion of all else.
If this Harvard study is to be believed, the Power of Hate might just have The Power of Love beaten out. Long story short, thinking evil thoughts gives you much more endurance than thinking good thoughts. There's probably reason why the trope is named UnstoppableRage as opposed to something more positive.
In Charles Fort's seminal work on paranormal phenomena, Wild Talents, he speculated that a rash of unexplained fires in English manor houses during the 1920s might have been caused by sheer focused hate from the working class during the General Strike.
The power that made the Schutzstaffel such ferocious enemies to fight on the battlefield. During their training in the boot-camps, they were taught to hate anyone who were classified as an enemy to the Third Reich. However, the Waffen-SS's fanatical fighting style led to high casualties and hence a debatable efficiency. Furthermore, they were a very minor part of the armed forces in Poland and France.
All armed forces do this to a degree, making it easier for their soldiers to kill in combat by dehumanizing the enemy.
