->''"Battle doesn't need a purpose; the battle is its own purpose. You don't ask why a plague spreads or a field burns. Don't ask why I fight."''
-->-- '''BlackKnight''' [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=345 flavor text]], ''[[TabletopGame/MagicTheGathering Magic: the Gathering]]''

WarIsHell? Not for this guy.

Fighting is everything to the Blood Knight. He lives for it. He might deliberately disadvantage himself in order to make fights last longer and loves to reveal that [[IAmNotLeftHanded he is not left-handed]]. It's not so much about winning or losing, morality, the motives of his allies, or even [[GlorySeeker the glory]], that drives this guy so much as it is the opportunity for a good fight.

A Blood Knight can be of any morality whatsoever. The most extreme types put their love of fighting AboveGoodAndEvil. If heroic, they will frequently be TheBigGuy in an ensemble, the character most likely to solve his problems by force of arms. They might make the less violent members of the crew a little nervous, especially if they go off on a [[BerserkButton hair trigger]]. If an antagonist, he has a good chance of being a WorthyOpponent, since he doesn't want to defeat the heroes, necessarily, just fight them. He might undergo a HeelFaceTurn if he can find someone [[DefeatMeansFriendship tough enough to beat him]] and join the hero's team, or simply betray his boss to [[StalkerWithACrush pursue and obsess]] over his [[FoeYay foe]] on his own terms.

Less pleasant characters with this trait may exist, especially if they are also the {{Big Bad}} or their [[TheDragon right hand men]] who will [[KickTheDog do all kinds of]] [[MoralEventHorizon horrible things]] to trigger his opponent's BerserkButton enough to fight seriously and give them a challenge. This type overlaps heavily with PsychoForHire.

Personality-wise, he can be a FlatCharacter (and quite possibly DumbMuscle) which just shouts [[TabletopGame/{{Warhammer40000}} "Maim! Kill! Burn!"]], or, if he's a little more sophisticated/developed, he can be a WarriorTherapist, WarriorPoet or even a GeniusBruiser. The latter cases are rare. He might be a [[BoisterousBruiser normal, jocular guy]] when he's not brawling, or he might take the fight so seriously that [[TheStoic he blocks out everything else]] and will therefore live only for battle. In some cases the Blood Knight fights because he's [[DeathSeeker looking for a way to die with meaning]].

The Blood Knight doesn't even have to be a particularly violent man most of the time. A common version found in Eastern fiction is the Wandering Martial Artist, who is WalkingTheEarth looking for strong opponents to test his skills against. This might be coupled with a love of fair duels and a desire to {{challenge|Seeker}} the [[SpiritedCompetitor best and strongest]]. This type still enjoys the thrill of the fight, but usually eschews the death and bloodshed aspect. A living opponent, after all, can improve their skills and provide an even better challenge later. DefeatEqualsFriendship is a common occurrence with these guys, their opponent's or their own.

If there's a whole society of guys like him, you've got a {{Proud Warrior Race|Guy}}. If the character likes the 'killing' part more than the 'fighting' part, they're a PsychoForHire. The EgomaniacHunter also thrives on aimless violent thrill and loves a worthy quarry instead of opponent. If a character is in it for the challenge rather than just the fight, then we've got a SpiritedCompetitor. The Blood Knight's love of combat may be platonic, or it may have [[InterplayOfSexAndViolence sexual undertones.]] It could also overlap with AxCrazy if their love of fighting crosses the line into psychotic violence and instability.

SubTrope of InHarmsWay. SisterTrope to CombatSadomasochist, TheRealMan, and BoisterousBruiser. Compare CavalierCompetitor. May be from a MartyrdomCulture and will nearly always believe that WarIsGlorious. If he (or she, though it's much rarer) is in the military, then he would almost inevitably be a ColonelKilgore. A MonsterKnight has a high chance of being one. A more violent example that nonetheless fights on the side of good may (or may not) be a SociopathicHero. Not to be confused with the [[Webcomic/{{Homestuck}} Knight of Blood]], who is very unlike this trope.

Oh, and just in case it wasn't clear, the character doesn't have to be a literal knight for this trope to apply. It is about the attitude, not the rank.

[[folder: Card Games]]
* ''TabletopGame/MagicTheGathering'''s [[TropeNamers Blood Knight]] card has a very appropriate quote: ''His is the fury of the wildfire, the boiling blood of the volcano. He fights you not because you've wronged him, but because you're there.''
** This and KnightTemplar are the worse aspects of the [[LightIsNotGood White/Red]] mixture, as seen in the Nobilis of War from the Shadowmoor block and the legendary creature Ruhan of the Fomori from the "Political Puppets" Commander pack.
** As hinted at below in the part about Radha, all native born and raised Keldons are like this, making them {{Proud Warrior Race Guy}}s. The thing is, they are fully aware that their warmongering is to their own detriment as a society, in that many of their abilities and mechanics work on an understanding that not fighting hurts, and fighting also tends to have some sort of extremist drawback. To whit:
*** Keldon Warlord (a single creature who gets stronger and harder to kill based on the number of total creatures (minus Walls) on the battlefield) ''"What if they threw a war... and everybody came?"''
*** Keldon Berserker: ''"They fight beyond fear, beyond thought, and beyond mercy."''
*** Keldon Twilight: If no one attacked during your turn, one of your creatures dies.
*** Keldon Arsonist: By sacrificing two of your own lands, you can destroy a single opponent controlled land. ''"Fields can be replanted. Settlements can be rebuilt. Burn it all."''
*** Keldon Vandals: ''"Keldons divide all their spoils into two groups: Trophies, and catapult ammunition."''
*** Keldon Firebombers: (Jamuraa being the country Keld is invading) ''"If they isn't enough of Jamuraa left to stand on, I will still claim it for Keld."''
*** Keldon Megaliths: A land card with the special ability to inflict damage on a single target on your turn, but only if you have no cards in your hand. This means that in a situation where a normal player would have absolutely no options, the Keldons will still find a way to hurt someone.
** There's even a recurring ability to some up this trope. Formerly in black, now mostly in red, "This creature attacks this turn if able" is a common drawback, forcing creatures with it to run into the fray even if means certain death.
** The Mardu Horde of Tarkir are very enthusiastic about combat, to the point where their Khan is a massively aggressive orc with the attack-each-turn drawback, and have a clan mechanic that gives them bonuses for attacking - such as increasing the power of spells, or giving creatures cast after the dust settles a useful enters-the-battlefield effect.
** The Gruul Clans on Ravnica engage in this when not fighting out of more legitimate grievances. Bolrac Clan ogres [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=366446 pick fights with buildings]] if they run out of other opponents, and their favourite holiday, Rauck-Chauv, [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=96960 basically consists of breaking stuff and punching people]].

[[folder:Fan Works]]
* ''Fanfic/ThousandShinji'': In this story [[FieryRedhead Asuka]] [[{{Tsundere}} Langley]] [[AcePilot Sohryu]] is a [[TheBerserker berserker]] of ''[[TabletopGame/{{Warhammer 40000}} Khorne, God of War, Anger and Blood]]''. She is a [[SuperSoldier consumate warrior]], fighting is her life and she can barely control her battle-lust [[spoiler:and eventually becomes the Goddess of War.]]
* In ''FanFic/WeaverNine'' Jack Slash, as in canon. He gleefully cuts a bloody swath through the criminal underworld. He is, however, a little more rational than most members of this trope, and reacts to a approach of [[TheDreaded Leviathan]] appropriately (though he does decide to fight, in the end).
* In ''Fanfic/{{Uplifted}}'' Otto Skorzeny and Jack Churchill. Churchill once famously lamented the end of World War II, and Skorzeny was his counterpart on the German side.
* All eight protagonists of ''FanFic/{{Morphic}}'' have some aspect of this, as a product of their [[HalfHumanHybrid unusual heritage]]. It's most pronounced with [[SociopathicHero Mia]], a half-insect with [[BladeBelowTheShoulder bladed limbs]], but even the resident NiceGuy eventually discovers an impulse to [[PlayingWithFire set things on fire]].
* The combat-addicted skahs wizards and warriors of Baravada in ''Fanfic/WithStringsAttached''. Unfortunately they were so good at what they did that they wiped out all opposition and haven't had anything to fight except each other for at least ten years. They're so bored and have so little to do that when, in a brilliant BatmanGambit, Ringo spreads the word that there are monsters in the distant GhostCity of Ehndris, practically the entire skahs population of Ta'akan drops everything to try to get down there and see if it's true.
* The fanfiction ''FanFic/MoreThanHuman'' has two blood knights: Butch and Buttercup. This personality trait is actually a major plot point that [[spoiler: connects the two together and allows them to bond.]]
* Kain who debuts during the Grazton arc of FanFic/TheTaintedGrimoire.
* Garrus Vakarian in ''Fanfic/MassEffectInterregnum''. For all that he tries to be good and honorable, he loves the parts where he gets to knock heads, because of how simple it is in comparison to justice and leadership.
* A ''Anime/MagicalGirlLyricalNanohaStrikerS'' fanfic called ''[[http://www.fanfiction.net/s/7419498/1/bSwords_b_and_bShields_b Swords and Shields]]'' has '''''Yuuno''''' of all people start to become one while developing a relationship with Signum.
* ''FanFic/TheImmortalGame'':
** [[TheDragon General Esteem]], whose main purpose in life is warfare -- hell, it's his ''Cutie Mark.'' He's so in love with war that he's disgusted by Celestia's peaceful regime, to the point that he willingly [[SealedEvilInACan releases]] [[BigBad Titan]], knowing that the latter shares his [[TheSocialDarwinist beliefs]], and will enable him to fight and kill as many ponies as is needed to enforce Titan's rule of Equestria.
** [[SuperpoweredEvilSide Nihilus]] also counts, as does [[TheAlcoholic Sir Unimpressive]] for a heroic example.
** It's is revealed later in flashback sequence that [[spoiler: [[BrokenAce Twilight's ancestor, Astor Coruscare]] was this. She was a powerful yet extremely ruthless commander of Celestia's army in the past. She'll happily slaughters an army just to make Celestia proud of her. Hell, [[NamedWeapons her]] [[MeaningfulName blade]] was named ''Sangrophile'', a '''blood lover'''.]]
* ''Fanfic/AceCombatTheEquestrianWar'' has Night Raven, a griffon soldier obsessed with fighting and killing ponies not because of hatred, but for ''fun''. Interestingly, while Night Raven comes off as borderline AxCrazy for most of the fic, he shows a bit of honor when [[spoiler: Fluttershy]] [[GracefulLoser defeats him]], managing to congratulate her on a "good kill" before he dies.
** On the other hoof, the good guys have Flare Star. Though she is ''not'' sadistic or prone to brutality, she is definitely more aggressive than most pegasi of the EAF. It's best shown in Chapter 6 of the sequel, ''Wings of Unity'', where she makes quite a show of bombing the Exile artillery; complete with a PreMortemOneLiner ("Here, catch!") and baring her teeth when she flies up to Tornado Swirl after making the kill.
*** A few Chapters later, Flare Star delivers a...rather ''thorough'' [[NoHoldsBarredBeatdown beating]] to a Exile mare named Pearl Eyes, reducing the confident rookie to [[VillainsWantMercy pleading for her life.]]
* Agent Diamond, from ''FanFic/AkatsukiKittenPhoenixCorporationOverhaul'', is halfway between this and completely AxCrazy. The main point is that a person's death doesn't mean quite the same thing to her as it does to everyone else, but she loves the sight of blood spilling. She is, however, more likely to enjoy a fight than she is to simply kill weaklings for sport.
* ''FanFic/AShadowOfTheTitans'' has [[AxCrazy Gadjo]], who loves nothing better than a good fight (except [[TrademarkFavoriteFood pie]]). His partner Machete qualifies as well.
* In ''FanFic/AFathersWrath'', Lu Xiaong who refers to himself as a Warrior instead of a ninja is this as even though he sides with [[BigBad The Jashinists]] He makes his intentions known that he plans on challenging the Leader soon enough. When Kakashi calls him out on using his strength to fight for them he laughs him off and claims he doesn't fight for good or evil he just fights.
* [[VideoGame/TheElderScrollsVSkyrim The Dragonborn]] in the CrossOver fic, [[http://www.fanfiction.net/s/7843635/1/Portalborn Portalborn]] loves battle, needs it. Fire for her is symbolical, an icon of her hunger of power, in accordance with having the blood of a dovah. Disturbingly, she loves the taste of elven blood. Especially when [[ImAHumanitarian eating tasty, detestable Thalmor]] in her [[OurWerewolvesAreDifferent Werewolf form]]. But when she [[UnstoppableRage rages however...]]. The difference is that she fights better when she's actually enjoying herself, rather when she gets truely pissed, she's unable to battle to the best of her ability. Her entire personality provides quite the contrast with the meek and nervous [[VideoGame/{{Portal}} Doug]] [[TechnologicalPacifist Rattmann.]]
* [[FanFic/ChiAndChakra Chi and Chakra's]] OC Ryoko Saotome is a moe blood knight. Outside of a fight she's an emotionally abused nervous wreck that will let people walk all over her. Fighting is the only time she really feels relaxed and happy. Unless [[BerserkButton someone she cares about is threatened.]] In which case you're looking at a berserker.
* FanFic/AGrowingAffection makes this a trait of Pein's Ashura Path. She can sense the combat skills of other ninjas as animal motifs, and see most of the ninjas around her as ants. When she senses a badger and a falcon (Gaara and Neji) together, she seeks them out hoping they will give her a good fight. She even tells them the Deva Path has left the Rain village, becauses she doesn't think either of them alone will be a match for her.
* [[Series/KamenRiderWizard Phoenix]] from ''Fanfic/FriendshipIsShowtime'', as with his canon self. This one actually gives a reason ''why'' he's a Blood Knight; he feels there's a void in himself he needs to fight to fill. In this canon, he's responsible for the events of "[[WesternAnimation/MyLittlePonyFriendshipIsMagic Dragonshy]]", solely to get Haru to fight him. After winning the first fight [[CurbstompBattle easily]], he even refuses to fight Haru again until provoked significantly. After being beaten by [[MidSeasonUpgrade Flame Dragon Style]], he becomes obsessed with fighting Haru.
** Iron Will in [[https://www.fimfiction.net/story/183015/iron-wills-foalcon-necrophilia-sex-rampage#comment/4242309 Iron Will's Foalcon Necrophilia Sex Rampage]] is this, because he quite clearly lives for the opportunity to rape and torture everyone he sees. There is also a sequel, which involves Iron Will getting released from prison and then gunning down vast hordes of gang members referred to only as "niggaz", and then molesting yet more underage foals before having an armed standoff with the police. Purely because he enjoys the thrill of violence.
* In the HungerGames fic ''Fanfic/SomeSemblanceOfMeaning'', several of the Careers (Amber, Achilles, Brigid) are shown to kill merely for the enjoyment of it. In fact, when they go for several days without encountering another tribute, they even [[spoiler: attack an innocent fawn. [[BerserkButton This is what causes]] [[JerkWithAHeartOfGold Obsidian]] [[HeelFaceTurn to leave the pack]] ]].
* In ''FanFic/DiariesOfAMadman'', Luna is very fond of battle, which doesn't gel well with the fact that she's not entirely sane to begin with.
* In ''Fanfic/AllTheWayBack'', the returned Princess Luna is very eager to find chances to serve Equestria as its Princess of War -- in part because it makes the lonely FishOutOfTemporalWater feel useful again, in part because she simply enjoys battle.
* ''Fanfic/PonyPOVSeries'' has Strife, the AnthropomorphicPersonification of Natural Selection. When called to exterminate a race, she prefers to fight them head on, even though she could simply wipe them out from a distance with her magic. She also says [[TheSocialDarwinist every race deserves the chance to fight for its survival]].
* In ''FanFic/MegaManDefenderOfTheHumanRace'', Punk seems to be this, and [[spoiler:Bass]] ''definitely'' is. In episode 11 he comments that he loves the sounds of war, and the only thing better is silence before victory.
* Yamzarat Machtoro from the crossover fic [[https://www.fanfiction.net/s/6731833/1/Angels-of-the-Storm Angels of the Storm]] is an ancient [[HumongousMecha Titan]] built by [[{{Precursors}} the ancestors of the Quarians]] to fight the Reapers. He was defeated then, but is woken up and wants revenge, and gleefully smashes his way from the beachhead in China to Beijing, taunting his ''allies'' about being too slow.
* ''Fanfic/KitsuneNoKenFistOfTheFox'': Tenten is always ready to fight, and in fact she'll willingly engage in bar brawls and street fights in an effort to make herself stronger.
* ''Fanfic/TheOmegaChronicles'' has a few examples of this, but the biggest one of them all? [[VideoGame/MegaManZero Omega himself!]] Every time he thinks a fight's gonna happen, you can bet your ass he'll be there to enjoy it. Hell, tell him a massive fight will happen and he'll get paid if he does a job for you, and you've got yourself one God of Destruction working for you.
* Harkin from ''[[FanFic/MyLittleUnicorn My Brave Pony: Star Fleet Magic III]]'', to the point wear he actually betrays Sombra over his feud with Lightning Dawn.
* Ichigo from ''WebVideo/OmniBleachAbridged''.
* Downplayed by Dante in ''Fanfic/DantesNightAtFreddys'', who insists he would rather sleep than battle the animatronics of Freddy Fazbear's Pizza, but is shown to have a lot of fun fighting them anyway.
* ''Fanfic/PeaceForgedInFire'': PlayedForLaughs when Captain Koren, the CO of the Klingon flagship, arrives to discover that she's missed the battle entirely.
-->'''Koren:''' Tal’Shiar scum! This is Koren, daughter of Grilka, Captain of the glorious IKS ''bortaS’qu''! You will—what the… What do you MEAN we missed out on a glorious battle? ARGH!!!!!! I haven’t seen any action since Qo’noS! Why does it ALWAYS take an impending apocalypse for me to get to kill things???\\
'''Brokosh:'''[[labelnote:*]]A Lethean, and originally a gun-for-hire[[/labelnote]] ''({{facepalm}})'' Koren, you damn fool, get back in formation.
* Bambietta Basterbine is this in Fanfic/AlabasterOrchestra, much like in canon, but begins to avert it (to an extent) after the point of divergence.
[[/folder]]

[[folder:Films -- Animation]]
* The titular villain of ''WesternAnimation/{{Megamind}}'' was like this. The reason is because he didn't want to conquer the world, but rather to find a worthy opponent to challenge and develop his skills and experience as a super-villain. As soon as he kills his own nemesis, he's left without a worthy opponent to reduce his boredom. So, he creates a new super-hero nemesis to give him a good fight, only for him to later on become more evil than Megamind himself and thus have to be stopped. [[spoiler: As soon as Megamind defeats his own creation, he ends up saving the city and becoming a super-hero instead, thus giving him more ''real'' challenges to feed his adrenaline-rush, even though it would mean retiring from the super-villain business to become said super-hero.]]
* Shan-Yu from ''Disney/{{Mulan}}'' is heavily implied to be this: He deliberately allows himself and the Huns to be sighted at the Great Wall of China as they breach it so they could send their best soldiers and thus have him prove his strength to them.
* Mari from the second ''Anime/RebuildOfEvangelion'' movie.
* Luo-Long from ''Anime/SwordOfTheStranger'' works this angle extremely hard. He's a European amid a group of hand-picked Ming Dynasty Chinese warriors, headed by an ancient noble who despises Luo-Long as a 'Western barbarian'. The old man's distaste really says something about Luo-Long's skill, that he was still chosen to come along. For his part, Luo-Long has access to painkillers that completely kill pain but don't slow down reflexes or the like, but doesn't use them because a fight wouldn't be interesting using them. He'll fight people just for fun (down to attacking a stranger just because the man has a sword) and it's implied he's a blond-haired, blue-eyed European hanging out in the court of the Ming Emperor because he was given asylum. He also hates the task he's a part of, as it means he hasn't fought anyone really worthwhile for a long time, and won't for the foreseeable future. It's only when he sees the hero fight that he thinks this whole trip from China to Japan has been worth it.
* ''{{Disney/Bolt}}'' gives us Rhino, a little hamster in a plastic hamster ball of all creatures. He is psychotically excited about getting to share in the dangerous stunts Bolt tries to pull, will willingly attack a cat, has threatened grievous bodily harm against a human ''twice'', and does all of this with seemingly no understanding of how small and vulnerable he is compared to everyone else he interacts with. Bolt himself can also qualify, but he at least has a {{Freudian Excuse}}.
[[/folder]]

[[folder: Films -- Live-Action]]
* Kurgan from ''Film/{{Highlander}}'' loved to fight and kill and was a sadist to boot.
* Stephen the Irish, in ''Film/{{Braveheart}}'', who seems more interested in killing Englishmen than winning wars or freedom.
* Colonel Hessler, the panzer commander in the 1965 film ''Film/BattleOfTheBulge''. For him life is to be spent in the turret of a tank, fighting until death takes you.
* Tallahassee from ''Film/{{Zombieland}}'' loves him some zombie-killin'. Give him a few guns and a couple of blunt weapons and he'll be off having fun for hours. And probably [[AxCrazy cackling maniacally]] while he's doing it too.
* [[ColonelKilgore Lt. Col. William Kilgore]] from ''Film/ApocalypseNow'' is an adrenaline junky who loves combat and the smell of napalm just as much as hanging ten on a surfboard.
* Emil Blonsky from the 2008 ''Film/TheIncredibleHulk'': held off being promoted out of the battlefield, despite his aging body (looking 45 when he's 39) for the sheer joy of being a "fighter", and when the opportunity to fight a foe as formidable as the Hulk arose, was willing to have himself transformed into a SuperSoldier and an outright abomination (no pun intended) to be able to have a "real fight".
* ''Film/TheAvengers'': The Hulk seems to exist to fight. He smirks when commanded to "smash."
* Brad Whitaker, chief villain of ''Film/TheLivingDaylights'' is somewhat of a slight subversion: He's obsessed with warfare and weaponry, his house practically a museum full of the stuff, is the leader of a mercenary company, and calls himself a "soldier". However, he flunked out of West Point for cheating, and in general is really only bumming around in Tangier.
* The Hessian (who was beheaded and became the HeadlessHorseman) in ''Film/SleepyHollow'' came to fight as a mercenary in America "for love of carnage".
* ''Literature/BattleRoyale'' brought out true intentions of students who really gained pleasure from killing their peers.
* ''{{Film/Deathwatch|2002}}'' has Quinn, the fur wearing psychopath who's first focus shot is him with his newly found spiked trench club. He also marks one of the few times a revolver bayonet is seen in cinema. Also, he collects scalps, making the origins of his furs somewhat questionable. He also remarked that he killed a man whilst on holiday in Blackpool. The film is essentially a horror version of Journey's end, set in a [[UsefulNotes/WorldWarI WW1]] trench.
* The predator aliens from the ''Franchise/{{Predator}}'' series. They use their advanced technology to travel around the galaxy and hunt the most dangerous game. When they find a WorthyOpponent, they even cast aside their high-tech weapons on occasion to even the odds and make things more entertaining. In ''Film/{{Predators}}'', Royce states that he himself is also an example. He loves the rush of battle and believes that most people who fight for a living do too.
* Gimli from ''Film/TheLordOfTheRings'': fearless, BadAss Dwarf, with shades of ViolentGlaswegian in his personality. Eager to avenge his race's ancestral grudge against Orcs, and in so doing racks up the largest single body count in all three movies. Oh, and played by professional LargeHam John Rhys-Davies.
* Mad Dog on in ''Film/TheRaid'' loves fist-fighting. Twice he disarms himself and allows his enemies a fair chance to defeat him in unarmed combat.
* [[Creator/JeanClaudeVanDamme Jean Vilain]], the BigBad of ''Film/TheExpendables 2''. He becomes so overjoyed when he finally fights [[Creator/SylvesterStallone Barney Ross]] that he urges him to keep fighting.
* At the start, Film/{{Thor}} is like any of Asgardian of legend: boastful, headstrong, and will gladly take any challenger to task in the name of his homeland. However spending some time on Earth weans him from his one-track mindedness.
* ''Film/{{Elysium}}'': Kruger and his squad-mates Drakey and Crowe.
* In ''Film/XMenOriginsWolverine'', Victor joins many wars for over a century only to keep his killer instincts satisfied. He enjoys being a warrior far too much to start a life of peace with James.
* Drax from ''Film/GuardiansOfTheGalaxy''; when the team gets into fights, he is clearly enjoying himself throughout, laughing like he's on a roller coaster while brutally slaughtering dozens of mooks.
** In that same vein, Rocket Racoon is simply a smaller, furrier version of Drax. He approaches firearms, explosives, and their use with all the giddy joy and level-headed justification of a serial arsonist. When he is finally given a weapon (a large, high-powered Gatling-esque gun that's twice his size) to use during the prison break, his reaction is essentially a barely-contained orgasm:
--> '''Rocket:''' [[PunctuatedForEmphasis Oh. Yeah.]]
* Jack, of ''Film/JackBrooksMonsterSlayer'', has long been possessed of sudden and unstoppable rages. By the end of the film, he's learned to channel them into killing monsters.
[[/folder]]

[[folder: Live-Action TV]]
* ''Series/{{Angel}}'': Illyria is quite fond of fighting and violence in general.
--> '''Illyria:''' ''"I enjoy hurting you."''
--> '''Illyria:''' ''"I've been hitting the half-breed. He makes noise."''
--> '''Illyria:''' ''"Wesley's dead. I'm feeling grief for him. I can't seem to control it. I wish to do more violence."''
* In ''Series/{{Workaholics}}'', Karl is a slightly Downplayed example of this trope, he likes to fight, but specifically at concerts, getting amped up by the music. The guys refuse to let him go to an Xibit concert with them because of his past, like biting through a little girl's ear, and throwing a rock at Reba. At the end of one episode, he pretends to be sleeping with Montez's wife so they will fight. He has slight elements of CombatSadomasochist as well, for he lets Montez get first hit (with a double-headed dildo) and says "Oh hell yeah bitch" as he gets knocked down. He's then laughing as Montez keeps hitting him.
* Dean Winchester in ''Series/{{Supernatural}}'' is an example of one. He loves hunting supernatural creatures.
--> '''Dean''': Let's kill some evil sons-of-bitches and raise a little hell!
** At the end of Season 5, Dean settles down with a girl and a kid and tries to live a normal life. He ends up leaving them for several reasons, but the most driving one being the fact that hunting was in his nature. It was a part of him, and he voluntarily abandoned a normal family life for hunting evil.
** In Season 9 Dean gets [[spoiler: the Mark of Cain]] which ratchets his normal Blood Knight tendencies UpToEleven whenever he [[spoiler: is holding the First Blade]]. In Season 10 he actually loses most of that bloodlust [[spoiler: because as a demon he can control the power of the Mark better]]
* Kate Argent, in ''Series/TeenWolf'', who is a Werewolf Hunter.
* ''Series/TokusouSentaiDekaranger'':
** Bisque, a one-off villain with a history to the {{mentor|s}} Doggie Kruger. An out-of-control berserker charged with 999 counts of illegal dueling to the death (all of which he won); he was so bad that he was passed over by his father for control of his family's dojo in favor of Doggie.
** ''Series/SamuraiSentaiShinkenger''/''Series/PowerRangersSamurai'' has Juzo/Deker, who is just as bad - and fixated on the Red Ranger as his next WorthyOpponent.
* ''Literature/GenerationKill'':
** Lance Corporal Harold James Trombley, who only seemed excited by killing people, even civilians.
** Cpl. Person gives this memorable rant in response to a child's letter from the USA.
-->"Dear Frederick, thank you for your nice letter. But I'm actually a US Marine who was born to kill, where you have clearly mistaken me for some sort of wine sipping communist dick suck. And although peace probably appeals to tree-loving-bisexuals like you and your parents, I happen to be a death-dealing, blood-crazed warrior who wakes up everyday just hoping for the chance to dismember my enemies and defile their civilizations. Peace sucks a hairy asshole, Freddie. War is the mother-fucking answer."
* Kara Thrace in ''Series/{{Battlestar Galactica|Reimagined}}'', as shown in the following quote.
--> "You know, everyone I know is fighting to get back what they had. I'm fighting because I don't know how to do anything else."
* ''Series/{{Blackadder}}'': King Richard IV (played by Creator/{{BRIAN BLESSED}}) is a comedic example, as a man who utterly revels in slaughter, orders his troops to attack his allies (telling them to just dress up as Germans), and goes on Crusades, not so much for religious reasons, as because he really likes to kill Turks using small pieces of cutlery. His attitude is best shown by his RousingSpeech before the Battle of Bosworth Field:
--> '''Richard IV:''' Let blood, ''blood'', BLOOD be your motto. '''Slit their gizzards.'''.
* Langston's father on ''Series/{{CSI}}'' returned from the Korean war but never stopped fighting, and would go out at night to provoke barfights. He once put several people in the hospital (and wasn't in good shape himself) and declared it "the best night of my life!" Langston fears this could be a [[InTheBlood genetic trait]], but nonetheless uses the story and the fact that he became a doctor to assure the son of an infamous SerialKiller that InTheBlood doesn't exist.
* ''Series/BuffyTheVampireSlayer'':
** Spike: violence isn't the ''only'' thing he lives for, but it's one of his very favorites. A flashback tells that he enjoyed fighting more than killing, and loved to go against the odds, infuriating the more "sophisticated" serial killer vampire Angelus, who much preferred to pick his victims carefully, and ensure their helplessness before he got to work. This side of Spike is even more prominently on display when he discovers that his violence-dampening chip doesn't prevent him from harming demons; he is so overjoyed that he ''can'' fight again, he doesn't even mind that he's helping the good guys by doing so.
** Faith, who equates fighting and killing with sexual pleasure, would count. Then she goes off the deep end.
** All slayers are this to some extent. In a Season 4 episode, Buffy was unable to sleep. So, she got out of bed, went on a hunt, chased down and killed a vampire, then returned to bed, finally able to sleep. As we also saw that season, a vigorous fight and kill makes her horny.
** When Simone didn't like the stance against guns, she starts by going rogue, arming up and developing an obsession with killing Buffy, and she gets worse from there.
* ''Series/DoctorWho'':
** The Sontarans are a race of Blood Knights. In spite of their short stature and potato-like heads, they have evolved towards finding thrill in combat. Born with a crippling weak spot on the back of their necks, they must always face danger head-on. War is all they care to know. When General Staal encounters the Doctor, he shouts angrily, "Legend says he led the battle in the Last Great Time War. The finest war in history and we weren't allowed to be part of it."
** They're also something of a deconstruction. Their attitude means that they fight as single warriors with no real tactical cohesion, and so they rely heavily on superior technology and dirty tricks. In a straight-up fight with human soldiers using conventional weapons in ''The Sontaran Strategum'' they were utterly massacred.
** In "[[Recap/DoctorWhoS6E1TheDominators The Dominators]]," the junior Dominator is like this, frequently disobeying, and risking their plan, in order to kill and destroy.
** Leela of the Sevateem, possibly the most badass and combat-oriented companion the Doctor has ever traveled with, is a rare example of a blood knight who's both female and one of the good guys.
--->'''Leela''': Enjoy your death, Rutan! As I enjoyed killing you!
* ''Series/{{Sherlock}}'': [[InHarmsWay John]] had shades of this. Likes the violence and danger of the Afghan war which he was forced out of due to an injury. Plus, he's ''very'' good at handing ass to criminals, despite him being a PintSizedPowerHouse, because he can get physical (especially if you [[BerserkButton threaten]] [[HeterosexualLifePartners Sherlock]]). Though he is pretty clever at solving cases (being a doctor helps).
* ''Series/{{Smallville}}'':
** Phantom Zone escapee [[Characters/SmallvillePhantomZone Titan]] is an alien SuperSoldier and ProudWarriorRaceGuy, portrayed by Wrestling/{{Kane}}. Having arrived on Earth he fights his way through biker bars, and criminal hangouts, eventually participating in underground gladiator-style competitions with Meteor Freaks, before finding the ultimate WorthyOpponent in [[Franchise/{{Superman}} Clark]]. Think of him as a {{Nigh Invulnerab|ility}}le wrestler with an attitude problem and you've got him.
-->'''Titan''': [[FamousLastWords Good fight.]]
** Clark becomes one under the influence of [[BrainwashedAndCrazy Red Kryptonite]], Bizarro, as well as Clark ''Luthor'' from [[MirrorUniverse Earth-2]]. Even the normal Clark gets in the act when he is in bad mood.
--->'''Clark Kent''': [[BringIt That all you got]]? (''[[Awesome/{{Smallville}} punches Bizarro into space]]'')
* All "true" [[Franchise/StarTrek Klingons]] are this. Even the good ones still love a good scrap.
* ''Series/StarTrekDeepSpaceNine'' provides an example in the least expected place: Leck, a [[ProudMerchantRace Ferengi]] "Eliminator" (read: assassin, he "eliminates competition") who is in his chosen profession for the thrill of a good fight, not for the profit - something that would be unthinkable for most Ferengi (though being in demand certainly doesn't hurt).
* In ''Series/{{Heroes}}'', Sylar spent a long time complaining that he didn't want to kill people to get power. But then in volume 3, he discovers how to get powers without killing. However, he still kills because it's "funner".
* ''Series/{{Merlin}}'' has Sir Gwaine, an actual knight. In his first appearance, he helps Arthur and Merlin in a bar brawl ''because'' they were outnumbered and he likes those odds. In the season three finale, he says he doesn't think Arthur & Co have any chance of succeeding in their attack to retake Camelot but he "wouldn't miss it for the world."
* Paige from ''Series/{{Charmed}}'', who's the most vocal about killing Cole in Series 5 and often the first one to suggest resorting to violence to solve a problem. Her tendency to do this led ''Website/TelevisionWithoutPity'' to jokingly [[FanNickname refer]] to her as "[[AxCrazy Raige]]". Fittingly, she wound up becoming the Goddess of War in the Titans two-parter.
* Anya from ''Series/{{The 100}}''. Through almost her entire fight with Clarke, she has a huge grin on her face, and even after being beaten up and almost killed, she's still smiling, and tells Clarke, with genuine approval, "You fought well."

[[folder: Music]]
* The narrator from Music/DavidBowie's "Running Gun Blues". Even after the war has ended, he still lusts for battle and blood, even to the point of committing random acts of violence on civilians.
%%* Most songs by Music/{{Manowar}}, including "Black Wind, Fire And Steel." %% Zero Context

[[folder:Myths & Religion]]
* [[Myth/ClassicalMythology Ares]] was one of the Greek gods of war. While Athena was goddess of wisdom and tactics, the domain of Ares was bloodlust and slaughter. He fights because he loves the violence. Which is not to say Athena doesn't relish in warfare (she is, after all a war goddess), as indicated by [[http://www.theoi.com/Olympios/Athena.html#Hymns this verse]]. She just is not ''as'' bloodthirsty as Ares. Then, there is Ares' sister and sidekick Enyo, whose epithets include 'blood-splattered', 'destroyer of cities' and 'impartial' - because she would support both sides of a battle to maximize the slaughter...
* Existing on the edge between mythology and history, the legendary Viking [[TheBerserker Berserkers]] struck fear in the hearts of all Europe during the Viking Age. Historians have put forth several different theories to explain the rage that seized these warriors on the battlefield, but ultimately, all that is known is that they would rush into battle with little-to-no armor, ignore wounds that would cripple an ordinary man, and strike down anything and anyone who got in their way. Contemporary accounts state that even their allies gave them a wide berth, for TheBerserker did not distinguish too well between friend and foe. According to their beliefs, a Berserker who fell in battle gained automatic access to the Warrior's Heaven of Valhalla (where they'd get to fight ''forever'' without dying, a Blood Knight's true paradise), and so they fought, not for plunder or honor -- but simply for the fight itself, [[DeathSeeker and for the eventual warrior's death]]. Dying outside of the battlefield would result in a FateWorseThanDeath for any berserker: not getting in to Valhalla.
* The Morrí¬gan from Myth/CelticMythology is famous for being the most fearsome ''goddess'' in most pantheons. She would often fight on ''both'' sides of a war depending on who was slaughtering more people, and specialized in making minor misunderstandings slowly escalate into country-wide bloodbaths. PoorCommunicationKills? No, she's ''[[TheChessmaster just that good.]]''
* The Asura of Myth/{{Hindu|Mythology}} and Buddhist religion. They loved to fight, and would seize on any opportunity to do so, whether it's for a good cause, an evil cause, or just for the hell of it. Which is why the race's name is often translated to ''warring deities''. In Buddhism, people who loved to engage in battle were often reborn as this. The Aesir, the Norse pantheon of sky gods, derive their name from the same Indo-European word that the name ''Asura'' came from.[[note]]Oddly, the {{Zoroastrian|ism}} angelic Ahuras and supreme {{God}} Ahura-Mazda also derive from the same root; however, Zoroastrianism flips the Indian and Norse system, with the Ahuras being good and peace-loving, and the ''Daevas'' (equivalent to the "good" ''Devas'' of Hinduism; the word is related to the Latin ''divi'' "diety" from which we get "divine") are evil, chaotic demons.[[/note]]
* The [[http://traditions.cultural-china.com/en/13T1371T2151.html Yazi]], one of the nine offspring of the [[DragonsUpTheYinYang Chinese dragon]]. They love fighting and killing and they are often depicted on the handles of weapons.
[[/folder]]

[[folder:Pro Wrestling]]
* Wrestling/{{WWE}} wrestler Finlay attained tweener status, being between {{Face}} and {{Heel}}, for the sole reason that he'll simply beat up anybody he comes across for kicks, not particularly caring whether they're "good guys" or "bad guys". His CatchPhrase sums it all up: "My name is Finlay, and I love to fight!"
* Wrestling/{{CHIKARA}}'s Wrestling/EddieKingston turned into this after his FaceHeelTurn in 2007, declaring his desire for a "warrior's death" and pledging to take all of his hatred and misery stemming from an industry that he felt didn't respect him out on anyone who got in his way.
* The night after the 2012 installment of WWE "Hell in a Cell", Wrestling/{{Sheamus}} (who had lost the [[http://www.wrestling-titles.com/wwe/wwe-world-h.html WWE RAW World Heavyweight Title]] at the event), came out and proclaimed with a smile that in spite of his loss, he got an amazing battle that he was thirsting for, regardless of the outcome. He declared Wrestling/TheBigShow a WorthyOpponent and said he was on pins and needles waiting for another swing at the world title.
[[/folder]]

[[folder:Tabletop Games]]
* In TheRealMan, every single Real Man is this.
* Both the ''TabletopGame/{{Warhammer}}'' and the ''TabletopGame/{{Warhammer 40000}}'' universe features several species and factions who exhibit this trope to varying degrees.
** The Orcs/Orks were ''bred'' for war and will gleefully fight anything, themselves included, if there's a good fight to be had from it.
** Worshippers of Khorne qualify partially -- [[PsychoForHire but their main interest is spilling blood and spreading death and mayhem in Khorne's name]], not in the quality of the battle. After all, "Khorne cares not from whence the blood flows, as long as it flows" -- they've been known to kill ''themselves'' if they run out of other victims to kill. The appropriately named Skulltaker, the highest ranking of Khorne's lesser daemons is this trope personified. His sole reason of existence is to look for the greatest warriors and fight them in hand-to-hand combat. If he wins (and he usually does) he'll rip the foe's head off and attach the skull into his cloak.
** Notably, the quote is interpreted differently DependingOnTheWriter. [[TabletopGame/BlackCrusade Those]] trying to make Chaos a bit less of a mustache-twirling ForTheEvulz villain go for the full trope, "from whence the blood flows" meaning the particular ''faction'', not the skill level of your opponent. Decapitating a fellow Chaos Champion is just pleasing to Khorne as slaying an Imperial hero, while killing a lowly cultist or citizen barely gets His attention.
** Dwarf Troll Slayers exhibit this, although it's case not a question of thrills: Seeking out the biggest and meanest foe you can think of and fighting it is essentially the [[DeathSeeker Dwarfs' form of honorable suicide]].
** Blood Dragon vampires subvert this; they're trying to emulate the first Blood Dragon Abhorash, who defeated a dragon and drank its blood, permanently quenching his blood thirst. The Blood Dragons have the goal of becoming great enough fighters to do the same, meaning that their constant fighting actually has the ultimate goal of allowing them to stop killing people. In the newer edition they're available only in squads of lesser vampires actually known as Blood Knights.
** Dark Eldar Incubi are essentially a dark reflection of the Aspect Warriors and are essentially entirely built around this trope. The Incubi don't fight for any higher cause, or even to improve their skills or find a worthy opponent. They fight for the sole purpose of killing, and everything else they do is to make them more efficient killers. Ironically, the Incubi are actually the most trustworthy of the Dark Eldar, as they don't care for things like wealth and political power and therefore have no reason to betray their employer (in fact, they apparently have a code of honor forbidding them from doing that), making them popular bodyguards for Dark Eldar Archons.
** While the Imperium's soldiers are generally better described as ChurchMilitant, the fact the many in-universe statements and preaches seem to consider warring against their enemies to be a way of worshipping the GodEmperor, it can get kind of confused at times.
** In the previous edition of the Chaos codex, Lucius the Eternal used to lower his stats IN GAME if he finds an unworthy opponent, and up his stats if he does. He also takes a memento of people who defeat him and take pride in it by fusing their souls to his armor.
** Plenty of Space Marine chapters have this as their quirk. [[NamesToRunAwayFromReallyFast The Manticores, Carcharodons, Executioners, Motifcators, Space Wolves (some of them, at least), Black Templars, Knights of Blood, Flesh Tearers and Angels Encarmine,]] to name but a few.
** The Minotaurs, a chapter that actually specializes in fighting other Space Marines. Because what is a worthier opponent for a Space Marine, than another Space Marine?
** Witch Elves of the Dark Elves are this trope, as well as Khainites in general. As the brides of the Elvin god of war, murder, pain, suffering, and blood shed in general, they go in a drug induced frenzy and rush in with a furry of attacks. Oh, and to make sure they kill something, they use poisons. Even other khainites are not too terribly sane as their khaineite rule prevents none chainite characters from joining them as no one trusts them.
* Several examples can be found in ''TabletopGame/DungeonsAndDragons'':
** The Elves of the Valaes Tairn in the ''TabletopGame/{{Eberron}}'' setting.
** The Battleragers in the ''TabletopGame/ForgottenRealms'' setting are dwarves enamoured with battle. While they also protect their home clanholds, the fight is what they desire most, and they run towards it with a fervent glee that give even drow pause.
** Garagos and Tempus in the ''Forgotten Realms'' campaign setting. The former is the divine exemplar of Blood Knightdom, a multi-armed bloodsoaked berserker who even makes the other gods nervous; the latter is a much more sensible war-god who likes fearless berserkers and isn't shy about bloodletting but avoids excessive destruction of resources or lives (which can be used for another battle) and generally advertises war as the most heroic pastime possible. He also does not consider [[ActualPacifist those who oppose his dogma]] real foes worthy of a conflict.
** If an [[OurOrcsAreDifferent Orc]] is given a motivation in ''D&D'', he'll probably be a Blood Knight (as opposed to [[OurGoblinsAreDifferent Hobgoblins]], who are {{Proud Warrior Race Guy}}s.
** Warblades, from the Book of Nine Swords, revel in melee and seek, above all else, to gain glory from combat.
* ''TabletopGame/{{Pathfinder}}''
** The chaotic neutral god Gorum, god of Strength, Battle, and Weapons. His followers are almost entirely all Blood Knights of one kind or another.
** Many half-orcs are also Blood Knights, to the point where a large group of them have formed their own Gorumite sect claiming Gorum is, in fact, the first Half-orc ever, and the reason he's always seen with steel armor covering all of his body is to hide his true appearance from human Gorumites, who wouldn't be able to handle his true appearance.
* The only way to escape the CrapsackWorld of pre-Ragnarok Midgard in ''TabletopGame/FateOfTheNornsRagnarok'' is to die gloriously in battle in order to be resurrected as an immortal warrior, to drink and fight every day until the end. Needless to say, the world is full of Blood Knights.
* ''TabletopGame/{{GURPS}}'' gives us the bloodlust disadvantage, and with it rules to handle playing a Blood Knight character.
* The Adamantine Arrows of ''TabletopGame/MageTheAwakening'' believe that reality expresses itself most profoundly through conflict (Existence is War) and so believe that conflict is the most viable path to enlightenment. They thus seek to become the ultimate warriors by honing their minds, bodies and souls (The Supernal is the Self) and training themselves in as many methods of combat as possible (Adaptability is Strength), then engaging in as much conflict as possible. However, they also believe that conflict is meaningless unless the warrior is fighting for an individual, office, organisation, or cause (Service is Mastery) and adopts some manner of code of honour (Enlightenment is Honour). The Arrow {{Sourcebook}} notes that in virtually every war in history, their were Arrows fighting for both sides, and includes an example of a character who was on both sides of the Vietnam War.
* ''TabletopGame/WerewolfTheForsaken'' has the Blood Talons, who consider the "hunter" aspect of a werewolf's existence the most important part. Almost all of their rituals involve someone's ass being kicked. Their extra part of the Oath of the Moon forbids them from surrendering in a fight unless they would make the offer to their opponent in similar circumstances.
* ''TabletopGame/TheDarkEye'' has the clerics of Kor, god of bloodshed and war, whose definition of a ''good fight'' almost crosses into CombatSadomasochist territory.
* ''TabletopGame/{{Exalted}}'': Slayers among Green Sun Princes are well-known for this. Their patron defines the smoldering rage that burns the world with overwhelming power.
** Any characters with high Valor in general are prime candidates for this treatment.
* ''TabletopGame/BattleTech'' the [[ProudWarriorRaceGuy Warrior caste]] of the Clans live solely for war, for them its better to die in combat than in of old age. Some Crusader Clans are more ruthless then the rest, such as Clan Jade Falcon, Smoke Jaguar, and Ice Hellion. Rather than die of old age, [[DesignerBabies "outdated"]] Clan warriors past 35 years old are reassigned to Solahma units, given an outdated assault rifle, and sent out as CannonFodder to distract [[PoweredArmor battlearmor]] and [[HumongousMecha battlemechs]].
[[/folder]]

[[folder:Theater]]
* Tybalt from ''Theatre/RomeoAndJuliet'' is one: During the opening fight scene, he states that he hates two things: peace and Montagues. At the party, he asks a page boy who is carrying his rapier to give it to him to he can kill Romeo, although he is stopped by Lord Capulet. And he sword fights with Mercutio even when Benvolio tries to negotiate.
[[/folder]]

[[folder:Visual Novels]]
* Lancer in ''VisualNovel/FateStayNight'' embodies this trope. He has no interest in the Holy Grail, only in beating the crap out of the other heroes in a good fight. Unfortunately, his Master does not share his Blood Knight tendencies, so there are only few moments he can fight on his fullest and enjoy the fight. And in the same series, Assassin. Only interested in sparring with other Servants. His drawback is that he is stuck on only one place and can't move freely. So he had to wait for the other Servants to come at him.
* Uruka and Takios in ''VisualNovel/EienNoAselia''. The former is rather honorable and the latter is something of a worthy opponent. Both of them serve as TheDragon to other villains. [[spoiler: Uruka later makes a heel face turn and admits that while she really likes fighting, she hates killing.]]
* Momoyo from ''VisualNovel/MajiDeWatashiNiKoiShinasai'' is impossibly strong and easily one of the most, if not ''the'' most powerful character in the entire series and only gets stronger as she grows older. This proves to be a tremendous asset when helping the rest of her TrueCompanions tackle whatever villain they're currently facing but also gives her a growing blood lust that can only be satiated by battling strong opponents. As Momoyo grows stronger, fewer and fewer characters prove capable of fulfilling this urge, which leads to the central conflict of her route.
* Ittosai from ''VisualNovel/YoJinBo'' loves fighting and killing, walking the line between this and PsychoForHire.
[[/folder]]

[[folder:Web Animation]]
* In ''WebAnimation/HomestarRunner'', Strong Bad's anime alter ego, Stinkoman, is a good example of a (comedic, and not very bloody) Blood Knight; he's always "looking for a challenge."
* ''WebAnimation/{{RWBY}}'''s Nora Valkyrie is just as enthusiastic about battles as she is [[GenkiGirl about everything else]]. Her response to being launched into a monster-infested forest is to ''smile''.
** Yang Xiao Long is one of the "seeks excitement" manifestations of this trope. It's suggested her reason for becoming a Huntress is to travel the world and find exciting fights. It's the only way you can explain a girl who deliberately antagonises an entire bar full of thugs. Even her Semblence reflects her fight-happy personality - [[CriticalStatusBuff her attacks become even more powerful when she gets hurt]].
** Ruby Rose is a more reserved example. She takes great interest in designing weapons and seeing them in action, and vocally expresses confidence in her abilities.
* ''WebAnimation/QuirkyMisadventuresOfSoldineTheCyborg''
** Soldine enjoys [[PayEvilUntoEvil reducing his opponents to pulp]]. Combat situations are also the only ones when he shows enthusiasm, because he's TheQuietOne most of the time.
** [[OurVampiresAreDifferent Handsome Rogue]] delights in chaos and mayhem, complete with PutTheLaughterInSlaughter.
* ''Machinima/RedVsBlue'' has Sarge, who practically delights in the Red/Blue conflict, and is the only one enthusiastic about it and its continuation. On top of this, it's implied that Sarge was an [[BadassNormal Orbital Drop Shock Trooper]] during the war.
[[/folder]]

[[folder:Web Comics]]
* ''Webcomic/GirlGenius'' got the Jagermonsters: Blood Knight {{Super Soldier}}s frequently slipping into {{Cloudcuckoolander}} territory. With {{Nice Hat}}s.
** Bangladesh Dupree is an AxCrazy example. And [[http://www.girlgeniusonline.com/comic.php?date=20040503 expects the same from others]]. Though aware of the differences enough to specify if "a town ''really'' [[ZombieApocalypse needed burning]]" or [[NotMeThisTime this time]] someone is killed not by her.
** Captain Vole, who is so bloodthirsty that the ''other'' Jagermonsters kicked him out. He initially joins up with Gil because the latter beat the crap out of him multiple times, but then makes it clear he is now perfectly willing to go with him simply because [[http://www.girlgeniusonline.com/comic.php?date=20120224 the ensuing civil war will be one of the most glorious things in history.]]
* ''Webcomic/TheOrderOfTheStick'':
** Belkar, the TokenEvilTeammate, is this. Just [[http://www.giantitp.com/comics/oots0439.html look!]]
** Tarquin, Elan's father, has shades of this as well. Just note [[http://www.giantitp.com/comics/oots0850.html his response]] when attacked by [[spoiler: the entire Order, sans Vaarsuvius]].
* In ''Webcomic/CircumstancesOfTheRevenantBraves'', both Mecha and by extension Sol are blood knights. Though in the latter's case, it's not necessarily by choice.
* Yatta-Ta of ''Webcomic/TheChallengesOfZona'' is, in part, a parody of this.
* Skoll of ''Webcomic/CryHavoc'' is a mercenary who enjoys her job, and welcomes being a werewolf as a chance to fight more.
* Sojueilo of ''Webcomic/{{Juathuur}}''.
* Ramael from ''Webcomic/{{Misfile}}'' is a former angel of vengeance who, after [[spoiler: killing two would-be rapists]] admits that he finds it addictive.
* ''Webcomic/{{Homestuck}}'':
** Jack Noir is implied to be this. He's compelled by general bloodlust, but he seems invariably drawn to fights that will challenge him most.
** Ironically subverted for Karkat, whose Sgrub title is ''Knight of Blood''. He's anything but this. The title is still appropriate, just not by human standards. His entire species has been in perpetual conflict because [[FantasticRacism they use blood color to define their caste system]], so anything related to blood without specifying color has to do with the unity of the race.
** The B2 session has Caliborn, one of two individuals who regularly contact the post-Scratch kids. He wants to get into the game seemingly just so he could satisfy his blood lust and turning it into a competition between Calliope, to the point where he seems to relish the idea of outright killing her.
* ''Webcomic/NahastLandsOfStrife'' gives us Thunder the warrior spirit.
* Webcomic/ZokushoComics: Serge really seems to enjoy shooting people. Raziel is also pretty gleeful at the thought of a fight.
* The Red-Haired Swordsman in Webcomic/TwoKinds, whose war-cry is "In the Name of Meaningless Battle!!!".
* ''Webcomic/MSPaintMasterpieces'' has Quick Man who LAUGHS when he is defeat and in pain.
--> Reader: Excited when we lose, grumpy when we win. That's Quick Man.
** [[CanonForeigner Allegro]], the eponymous Greatest Killer, also falls into this.
* In ''Webcomic/SchlockMercenary'', most of the mercenaries are {{Private Military Contractor}}s because of the money, their severe personality dysfunctions, a legally awkward situation in UNS space, or some combination of the above. Schlock, on the other hand, views the money as a nifty bonus that can be converted into Ovalkwik, guns, or both, and actively looks for the chance to get involved in carnage. It might be because amorphs don't really die, just get absorbed into the others, or it might just be because he's kind of nutty.
-->'''Schlock:''' With these, I could have put a five millimeter pulse-bolt of plasma through Snipey McWipey's scope and into his brain. One shot, no collateral damage.\\
'''Kevyn:''' But that's not what you ''would'' have done. If you'd had plasma cannons you would have [[ThereIsNoKillLikeOverkill hit his window with a two-meter blast, vaporizing him and setting the room on fire]]. Am I right?\\
'''Schlock:''' Okay, that does sound like it would have been more fun for me.
[[/folder]]

[[folder:Web Original]]
* The aptly named Battle from the ''Roleplay/GlobalGuardiansPBEMUniverse'' is a [[SuperStrength super-strong]] {{Nigh Invulnerab|ility}}le woman whose idea of a good time is challenging entire bar's worths of Hell's Angels to fights... sometimes without bothering to issue the challenge first.
* ''Roleplay/SurvivalOfTheFittest'';
** Vesa Turunen of version two shows signs of this in his death scene, even believing that his death at the hands of [[spoiler: Damien Carter-Madison]] was honourable enough to make up for his past mistakes and allow him to get into Valhalla. Version three character Adam Reeves, while mostly a [[TheSocialDarwinist Social Darwinist]] JerkJock, also has a few Blood Knight tendencies, as while he enjoys tormenting his weaker classmates and pushing them around he enjoys fighting the ones brave enough to push back even more.
** Tyler Lucas from version 5 is also heavily implied (and confirmed by WordOfGod) to be one. He's known for starting physical altercations with the other students, seemingly because he enjoys the very act of fighting with others.
* In the ''Literature/WhateleyUniverse'' stories, there's Counterpoint. He's a power mimic, among other powers, so whatever you've got, he's got too (within limits). He's regarded around campus as pretty psycho, since all he wants to do is find worthy opponents and fight them. If he loses, he comes back and tries again. And again. And... He isn't interested in killing people, just beating them. Now it looks like Counterpoint might be the avatar (or something) of the Greek god Ares, so that actually makes sense.
* ''Wiki/SCPFoundation'': SCP-076-2 seems to see combat as the only worthwhile pursuit in life, and agreed to work with the Foundation instead of slaughtering them because he realized it could provide him with ''more dangerous'' creatures to fight. [[spoiler: Backfired on the Foundation immensely when he got bored. He slaughtered his way through countless Foundation agents in what is currently the worst breach the Foundation has experienced so far.]]
* In the web serial [[http://stonesoulserial.blogspot.com/ Stone Soul]] there are several characters that fit this trope, all of whom are from the Ovleni culture. However, they do not simply love to fight. The Ovleni culture is quite fixated on experienced the most amazing and intense sensations that can be found. In the serial, the "ultimate experience" they are usually after involves battle-axing people in the face. However the use of psycho-active plants is also featured heavily, and battle and hallucinogens are also combined in some instances in pursuit of the ultimate experience.
* Taylor from ''Literature/{{Worm}}'' is not a combat monster, but she is a strategic genius who specializes in controlling the battlefield and developing strategies, and it's been suggested by at least one of her close friends that she ''lives'' for moments of great danger, when she is outnumbered and outgunned and the world is at stake.
* AJ from ''LetsPlay/TwitchPlaysPokemonCrystal'' has occasionally been written like this, as has his direct successor [[LetsPlay/TwitchPlaysPokemonEmerald Camila A Slash]] - though while AJ is definitely in it for the fighting and vengeance, Camila's motivations for her violent streak are a little hazier.
* Many characters in ''Roleplay/ThisIsWar'', ranging from simply enjoying combat, to enjoying the feeling of winning a fight, to grimly enjoying killing a particular species, it's all there.
* Golgotha from ''Franchise/{{Noob}}'' gets bored if she has to do a quest without any battles and frustrated if battles happen but are too short.
* The aptly named War from ''WebOriginal/FalloutIsDragons''. [[spoiler:After the heroes killed him, he turned down a resurrection on the grounds that he would probably never find such a thrilling fight again.]]
* Zanthosus, Sonikdude, and Xbaxman from'' WebVideo/WaterGlassGaming'' are this when playing Burnout Revenge. The video in question is titled "Soccer Mom Massacre". They claim to have killed a soccer mom on her way to pick up her son from practice, a prostitute down the street that got impaled with some car shrapnel, Mr. Miyagi, a drug dealer, and Mr. Smith who was coming home from work to his wife when he got killed.
[[/folder]]

[[folder:Western Animation]]
* Norman in ''WesternAnimation/MightyMax''. [[CatchPhrase He eats Blood Knights for breakfast!]] In one episode in particular, he responds to all problems with "Want me to break it?"
* ''Franchise/{{Transformers}}'' has quite a few of these.
** [[ProudWarriorRaceGuy Dinobot]], from the ''WesternAnimation/BeastWars'', fits the trope to a tee. He's all about honor and glory, and abhors an unfair fight because there's no honor in winning that way. He can't let a "Clear out" order by without at least one objection, either.
---> "I prefer to beat my opponents the old-fashioned way: '''brutally!'''"
** There's also Quickstrike, who will fight anyone, anytime, anywhere, while speaking in an incredibly stereotypical cowboy accent.
** Scourge, from ''Cybertron'', refuses to listen to anyone who won't face him in combat.
** Sunstreaker from Generation 1 (comics and cartoon) was a SociopathicHero version of this, generally willing to run right into a heavily guarded Decepticon outpost and try to outright fight everyone inside at once. He also happens to be a huge {{Jerkass}}.
** Megatron in all his incarnations has grand designs to conquer the universe. Destroying Autobots is his greatest joy. He destroys everything he touches [[LargeHam because everything is food for his hunger. His hunger for power!]] Of course, different incarnations are different when it comes to whether or not he loves to smash. Some versions are patient schemers and some versions love to get into the fight personally and smash some Autobots... and if you're a Decepticon, you'd ''still'' better stay out of his way when he's in this mood. G1 Megatron interestingly goes through several types over the course of his existence: as Megatron he's a campy cartoon villain. Upgraded to Galvatron in TheMovie, he becomes smart, patient, and using his increased power in conjunction with brains. Processor damage results in Galvatron becoming the biggest Blood Knight in franchise history, all about mad schemes and maximum destruction.
* Numbuh Four from ''WesternAnimation/CodenameKidsNextDoor'' suggests we beat the [[GoshDangItToHeck crud]] out of those [[CreepyChild Delightful dorks]]!
* In ''WesternAnimation/Ben10UltimateAlien'', Ben and Gwen's cousin Sunny only decides it's fun being around them once she gets to fight. Ben is also eager to get into fights for him to go alien, and beat up bad guys... A desire that's amplified even further if the alien he turns into happens to be Rath.
* In ''WesternAnimation/MegaMan'', Proto Man seems to only be happy when he's fighting--sometimes, only when it's with Mega Man.
* Binky Barnes from ''WesternAnimation/{{Arthur}}'' was hinted to have shades of this in one episode. During a summer workshop session, he and Sue Ellen were doing a Karate Match, and he manages to win against Sue Ellen, only for him to be upset that she lost due to realizing that she didn't even bother to try and beat him (due to thinking from one of Francine's Sister's Teen Magazines that kids hate people who are exceptionally skilled), sending him into a deep amount of depression which was only cured when Sue Ellen managed to actually defeat him in Karate after getting her act together.
* Hank's father Cotton from ''WesternAnimation/KingOfTheHill'' loved fighting in World War II and often told others of his actions he would've continued to fight in other wars had the Japanese not blown his shins off, he will still pick fist fights if he feels he has to, usually to defend his honor, he is a formidable fighter for someone of his size and sometimes has to be restrained before he can kill someone if angered enough.
* Buttercup of ''WesternAnimation/ThePowerpuffGirls'' enjoys fighting the most out of her sisters and will sometimes tell others of her battles. She also has a habit of sometimes taking it too far and is disappointed when a monster won't fight back.
** She doesn't take too kindly to [[BerserkButton the Professor or her sisters being threatened]], though. You've been warned.
* Brock Samson from ''WesternAnimation/TheVentureBrothers'' vacillates between someone who solves things violently because there is no other way, and someone who relishes an opportunity to fling blood across the room. Rarely limits himself to mere incapacitation when dismemberment is an option.
* Finn of ''WesternAnimation/AdventureTime'' once entered into a battle arena [[GenreSavvy he knew to be a trap]] just so he could fight gladiator ghosts.
* Toph Beifong from ''WesternAnimation/AvatarTheLastAirbender'' is a [[PintsizedPowerhouse short]], [[HandicappedBadass blind]] girl who routinely (and gleefully) kicks the asses of grown men almost three times her size. When she tells her parents about this, she states that she loves fighting and being an [[DishingOutDirt Earthbender]], and that she's really good at both.
* When she's first introduced, Korra from ''WesternAnimation/TheLegendOfKorra'' loves to fight and picks battles just for fun. She sees bending as purely a physical skill and ignores the spiritual side of being [[TheChosenOne the Avatar]]. CharacterDevelopment sets in slowly but surely, however, and over the course of the series, she mellows out and becomes a great deal more diplomatic.
** On a more sinister note, there's the Book 3 [[MakingASplash waterbender]] [[DarkActionGirl villainess]] [[HandicappedBadass Ming-Hua]] and her recurring habits of threatening everyone and grinning evilly in battle.
* Manny Rivera's mother Maria in her alter ego Plata Peligrosa from ''WesternAnimation/ElTigre''. She is reluctant to use the glove that gives her powers because it makes her very bloodthirsty. At first, El Tigre enjoys fighting crime with her, but once they run out of criminals to fight, she releases them from prison [[StartXToStopX so she can fight them again]].
* In the short-lived animated version of ''WesternAnimation/TheTick'', The Tick once notably said, "I don't want to stop evil. I just want to fight it!"
* Yang from ''WesternAnimation/YinYangYo'', whose favorite hobby is to "hit stuff" and even struggles to suppress it at times. Yuck is an evil example, since he's gotten his aggression from Yang.
* ''WesternAnimation/TeenTitans'': [[BadassBookworm Raven]] could possibly be this, as well as her allies, but most notably Raven. [[BewaretheQuietOnes God help you if you really piss her off by messing with her friends.]] [[CurbStompBattle She'll kick your ass if you do.]]
* In ''WesternAnimation/TeenTitansGo'', all of the Titans except for [[OnlySaneMan Raven]] have shades of this.
* Princess Star Butterfly of ''WesternAnimation/StarVsTheForcesOfEvil'' is [[GenkiGirl an endless fountain of energy]] who ''loves'' fighting monsters. Her friend Marco Diaz was a safety-obsessed kid who thought his life was boring until he got caught up in her adventures. Now he relishes fight fighting along side her.
