War Is Hell? 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 he is not left-handed. It's not so much about winning or losing, morality, the motives of his allies, or even 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 intense ones put their love of fighting Above Good and Evil. If heroic, they will frequently be The Big Guy 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 hair trigger. If an antagonist, he has a good chance of being a Worthy Opponent, since he doesn't want to defeat the heroes, necessarily, just fight them. He might undergo a Heel-Face Turn if he can find someone tough enough to beat him and join the hero's team, or simply betray his boss to pursue and obsess over his foe on his own terms.
Less pleasant characters with this trait may exist, especially if they are also the Big Bad or their right hand men who will do all kinds ofhorrible things to trigger his opponent's Berserk Button enough to fight seriously and give them a challenge. This type overlaps heavily with Psycho for Hire.
Personality-wise, he can be a Flat Character (and quite possibly Dumb Muscle) which just shouts "Maim! Kill! Burn!", or, if he's a little more sophisticated/developed, he can be a Warrior Therapist, Warrior Poet or even a Genius Bruiser. The latter cases are rare. He might be a normal, jocular guy when he's not brawling, or he might take the fight so seriously that he blocks out everything else and will therefore live only for battle. In some cases the Blood Knight fights because he's 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 Walking the Earth looking for strong opponents to test his skills against. This might be coupled with a love of fair duels and a desire to challenge the 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. Defeat Equals Friendship 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. If the character likes the 'killing' part more than the 'fighting' part, they're a Psycho for Hire. The Egomaniac Hunter 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 Spirited Competitor. The Blood Knight's love of combat may be platonic, or it may have sexual undertones. It also may overlap with Ax-Crazy if their love of fighting crosses the line into psychotic violence and instability.
Sub-Trope of In Harm's Way. Sister Trope to Combat Sadomasochist, The Real Man, and Boisterous Bruiser. Compare Cavalier Competitor. May be from a Martyrdom Culture and will nearly always believe that War Is Glorious. If he (or she, though it's much rarer) is in the military, then he would almost inevitably be a Colonel Kilgore. A Monster Knight has a high chance of being one. A more violent example that nonetheless fights for the side of good might also be a Sociopathic Hero. Not to be confused with the 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.
It's been lampshaded by Kenpachi, Grimmjow and his own inner hollow that Ichigo is a Blood Knight who is simply living in denial.
Kenpachi Zaraki, captain of an entire division of this trope. Fighting is his only reason for living and he will deliberately handicap himself in battle to ensure a good fight. He turns on his own people to help Ichigo, not because he believes in Ichigo's cause, but just because it'll get him close enough to Ichigo to instigate another fight with this Worthy Opponent. Deconstructed later on when it's revealed his interpretation of his idol Yachiru Unohana led him to erroneous conclusions about both fighting and her. As a result, his interpretation of this trope has been making him subconsciously weaker than he really is. Yachiru Unohana has to thrash him with the truth (and literally) to make him understand the truth.
Kenpachi's main subordinates (Yachiru (yeah that Yachiru), Ikkaku and Yumichika) revel in being this trope just as much as Kenpachi does. It's also made clear that ex-division members Iba and Renji are the same.
Grimmjow and Nnoitra live for fighting. Both have the goal to become the absolute strongest and through battle as the only way. The main difference between them is that Grimmjow wants to succeed at becoming the strongest whereas Nnoitra is the Death Seeker who wants to die in glorious battle to a Worthy Opponent.
Byakuya eventually learns, to his surprise, that not only does he have a capacity for instigating the madness of battle that is associated with a Blood Knight, he thoroughly enjoys fighting that way, too. He even thanks the opponent that created the insane fight that led to this discovery (right after blasting a hole through said opponent's chest, of course).
Unohana is eventually revealed to be a blood knight who has been repressing this side of herself for centuries until brought out of retirement by the Vandenreich's attack on Soul Society. She is, in fact, the original Yachiru that Zaraki idolised, who sees Zaraki's battle attitude as her greatest mistake that needs to be fixed. Her own idea of what it means to be a blood knight is much different, much more brutal, and definitely does not involve holding back in battle. It's equal parts disturbing and awesome.
Gremmy Thoumeaux's incredible Imagination-Based Superpower made him bored, as everyone is either too scared to fight him or unable to put up a fight. Then he faces Kenpachi... and for the first time, he enjoys the fight, for the prospect of crushing a Worthy Opponent.
Girge from Break Blade is a unique case. While being clearly an ax-crazed example in the battlefield, he maintains a polite attitude outside of it. His appearance alone played this trope straight; red hair, red uniform (despite being his standard uniform as a soldier), and red golem. Not to mention the glasses, and his reputation for killing his teammate in the past. Makes you wonder if he's a reincarnation of something evil...
KurodoAkabane from Get Backers is a perfect example; he only takes on Transporter assignments that can provide him with "the greatest possible amount of amusement" through the conflicts that inevitably ensue.
Hellsing : Oh, where to begin: Alucard, Anderson, basically all of the members of Millenium as well as several additional members in both the Hellsing and Iscariot organizations, the list goes on and on. Pick any random character in Hellsing, and he or she is probably a blood knight (except Seras Victoria). The Major, in particular, has an entire speech about how much he absolutely loves war that goes on for five minutes.
Pip Bernadotte comes from a line of blood knights. According to his grandfather, the men of his family have been "fighting for pennies" since the time of his "grandfather's grandfather's grandfather" but implies that they're mercenaries because it let's them earn a living from fighting.
Hakuron and Di Long in Haou Airen. A sort-of Justified Trope since both of them are high-ranked Triad members and their fighting skills are what brought them as high in the hierarchy as they are.
Wrath, a.k.a. President-Fuhrer King Bradley, from the manga and second anime. Near the end of the story, he's fulfilled his part in the Big Bad's plan and is bleeding to death with no chance of getting healed anymore. He challenges the good guys to a fight just because.
"It's nice to be face to face with death every once in a while. Right now, the only thing in my mind is the fact that I'll fight to the death with you. Social status, career, origin, race, gender, name... none of that matters. Not being bound by anyone and fighting just for the sake of it. How astounding. I've finally reached this stage."
Yomi used to be like this, raiding fortresses and ransacking villages for the sheer hell of it. The only problem was that his actions pissed off his Magnificent Bastard partner, Yoko Kurama. Eventually, Yomi pissed Kurama off enough that Kurama decided to cure Yomi of his Blood Knight tendencies in the worstpossible way. It works, and Yomi becomes a cold, ruthless and absolutely great Magnificent Bastard who rules a third of the Demon World. However, the ruckus caused by Yusuke and his proposed tournament reignites the fire of his inner Blood Knight...
Akagi doesn't just live for fighting, he would gladly die for a good fight, and believes that death is the essence of fighting. Only replace "fighting" with "mahjong".
Kotaro is a self-admitted example... mostly because, as he admits, fighting is really the only thing he knows. Once he does a Heel-Face Turn this is turned more into a love of testing his strength, while fighting for his friends. In this respect, as in many others, Kotarou is a Generation Xerox of Negi's father's rival, Jack Rakan. When Rakan dies, his last words are to tell his killer that it was fun, and he should really learn to enjoy this sort of thing more.
Akamatsu once made a point through Anti-Villain Wilhelm about the advantage of being blood-thirsty and fight-happy because there simply isn't any logical reason to do so otherwise; if one can't fight all-out, then there's no reason to fight at all.
Vinland Saga: It can be argued that nearly every single character is a Blood Knight to one degree or another. After all, they are Vikings. Thorkell the Tall takes the cake though, as his entire reason for choosing a side was who would provide the better fight. And when he sees an even better fight, he changes sides immediately. He looks kind of like a Danish Kenpachi as well.
Gantz's Kaze is a perfect example for the Eastern 'wandering warrior.' Also Izumi doesn't fight to revive someone or be freed, he only feels alive when fighting/hunting.
Mugen in Samurai Champloo frequently ditches his companions to go out and challenge the various tough guys he hears about on the journey. A handful of the antagonists also have this trait, particularly Shouryuu, the renegade, psychotic samurai whose goal is to get everyone to realize what a great fighter he is by hunting down, challenging, and killing all the best fighters in the region.
Similar to Mugen is Revy, as they both have almost the exact same personality (though Mugen may be slightly more nihilistic). Revy is a Sociopathic Hero who gleefully indulges in the carnage that she finds herself in, often sporting a Slasher Smile and becomes obsessed with an enemy if they are shown to be particularly deadly or skilled.
Balalaika is an example of this, and one whose love of war and carnage unsettle even Revy.
Cyberdramon. Just to drive the point home, his catchphrase is "Are you my enemy?" and his Image Song is "Dead or Dead". For a guy with multiple personalities, he seems to have his priorities sorted out.
Also Craniamon, a Royal Knight who wants nothing more than a good fight. Unfortunately because he's so strong, he can never find one.
The Fire Civilization from Duel Masters is, essentially, an copy of Red from Magic: The Gathering, so it's no surprise that this is the attitude you get from its cards.
Inuyasha qualifies as one particularly when he goes berserk. The entire Band of Seven are blood knights. Particularly Jakotsu.
Kiri Nanaya, Shiki's father, showed this trope once. In his first meeting with a young Kouma Kishima, he blinded one eye, but did not kill him because he knew someday he would give Kiri the fight of his life. The last fight of his life, as it turned out.
Lordgenome may count. Granted, many centuries of his life he just sits on his throne while surrounded by an infinite supply of consorts as RULER OF THE ENTIRE EARTH. However, if there's a rebellion that manages to get to him not counting the only one ever shown (now doubt others happened before this one) by the Dai-Gurren Brigade, he gets off his lazy ass and defeats them himself. Oh, and his head catches on fire in the heat of battle from his pure, raw manliness. Granted, he was defeated by Simon in the end, he did it in style. After some fighting, his mech is destroyed. What does he do? He scolds himself for relying on that stupid robot and destroys his opponent's mech bare handed.
In Parallel Works 8, which shows his backstory, it shows him at war with the Anti-Spiral, as General of at least 1/4 of THE ENTIRE WORLD'S ARMY. The war goes on for centuries and eventually the Anti-Spiral shows Lordgenome the Spiral Nemesis. In order to save the universe, he gives in. However, none of his millions upon millions of soldiers agree with him, so he kills every single one of them SINGLE HANDEDLY.
Roronoa Zoro. During his normal day, he does nothing but drink, sleep, and get lost when he's going around anywhere. Then someone wielding a sword pops out and... magic! Zoro becomes super energetic, draws his three (3!!) swords and starts to happily swing them. Which usually results into his enemy being sliced up pretty well. He often says he loves the fights; he can be really brutal; and, after all, his dream is to become the world's best swordsman (but, okay, that's to fulfill a promise to his long dead childhood friend).
Most swordsmen not aligned with The Government, being Daz Bones, Ryuuma and Ohm. Kaku is an affable exception, though.
Rob Lucci is one taken to the evil extreme.
Luffy can be considered one as well. It's obvious that his two best talents are eating and fighting, not to mention how he solves most problems with violence. He (along with Zoro) also had the desire to fight Burgess at Mock Town in the Jaya Arc simply because Burgess was a "champion". Recently, Luffy took part in a tournament and expressed that he couldn't wait to fight. When it does show him fighting, he's having the time of his life with a big grin on his face.
Jesus Burgess loves to fight and considers himself a "champion". On his first appearance, he's shown going around town and fighting random people simply because he felt like it. Not to mention that when he is shown fighting, he always has a huge smile on his face. A Blood Knight indeed.
Goku is this even as a child, gleefully entering into battle at any chance he gets. As the series progresses, he becomes more serious about it. There have been countless instances where Goku could've EASILY ended the fight with the villain of the week, but prolonged it just for the sheer sake of a good fight. This has, on occasion, come back to bite him (and the world around him) royally in the ass.
After winning against Vegeta in Dragon Ball Z, who was responsible for the deaths of several Goku's friends and almost destroyed the Earth not long ago, Goku (who's in just as bad shape as Vegeta) tells Krillin to let him live so they can have a rematch. This works to the world's advantage, as Vegeta ends up becoming The Lancer two arcs later.
Even later, he went as far as training the (redeemed) reincarnation of the most destructive being in the Universe just so he could fight him again.
Once the Saiyans are introduced, it's established that they're all Blood Knights too. An obsessive desire to fight, particularly against strong opponents, is innate to Saiyans. In fact, baby Saiyans are sent to planets in need of depopulation, since it's in their nature to happily fight and kill until there's no one left. Saiyans are practically made to fight. That is why they age very slowly, because they need their youthfulness to fight as long as they live.
It could be argued that Dragon Ball Z is an unintentional deconstruction of the Blood Knight, since due to Goku and Vegeta's Blood Knight tendencies, they're responsible for alot of the problems that the Earth faces.
Cell, being made partially from Saiyan DNA, became a Blood Knight to the fullest once he achieved "perfection". He was only concerned with testing out his new body and strength, and set up the Cell Games just so he could fight Earth's strongest warriors and have a little fun before he destroyed the planet.
Char Aznable and Zechs Merquise are dedicated warriors, finding their only true purpose in battle. Even better examples are Domon Kasshu and Master Asia, though they don't seek to kill their opponents, their main purpose to live is to fight and therefore show their feelings. Domon in particular admits that the only way he knows to express his feelings is by punching people.
The brutal Ali Al-Saachez of Gundam 00 has no qualms against admitting that all he lives for is war, and fears the day that men like him will no longer be necessary. During his final battle with Lockon Stratos, he is asked why he carried out a series of bombings in Ireland some years ago. His response? "Because I'm a mercenary, It's What I Do!''
Desil Galette from Gundam Age is quite possibly WORSE than Ali when it comes to this trope. He believes that wars are fun and that the soldiers and mobile suits are his toys. During episode 14, Flit asks why he killed Yurin. He admits that there was no reason; to Desil, it just meant that he lost another toy.
Yazan Gable of Zeta Gundam is almost as bad as Ali. He specifically joined the army so he'd get the chance to fight and kill AEUG members. Yazan is a more rational fighter than most Blood Knights, though.
Dorothy Catalonia of Gundam Wing is a female example, obsessed with the glory of war. She controls Zechs' mobile dolls for him, watches battles with almost orgasmic fervour, and in her final duel with Quatre seems to be actively trying to get him to kill her. Possibly subverted by Treize Khushreneda; he claims to be a Blood Knight but it may well have been a pose.
Guts sometimes has a reason to fight, but most times he does it just because he enjoys it, good guys or bad guys be damned. To make it even more obvious, he gets a Slasher Smile every time he is about to go into combat. He reaches absurd levels in the "Lost Children" Arc, when his inner beast takes a definite shape and starts haunting him.
Nosferatu Zodd, who loved combat so much he became a demon in order to continue raising the stakes. It goes beyond saying that their encounters have been insanely rough.
Gaoh is Large and in Charge, the biggest person on the entire cast, and so tough he has to wear a titanium mouthpiece because he'll chew through anything weaker. Doesn't feel any need to hold back his incredible strength because he expects his opponents to give it their all as well. Despite that, and the fact that he's caused several career-ending injuries, he's actually a pretty decent guy.
Gaoh's also shown a good deal of respect for individuals simply because they were willing to face him head on, even if they had no strength to provide him a challenge. Sena managed to do this when he moved towards Gaoh (and risking horrible injury) rather than another player who while they wouldn't have hurt Sena would have very likely taken the ball due to that players skills.
In fact, when Banba prevents him from crushing the quarter back for the first time in his career, he pays silent tribute to him. When an idiot in the crowd jeers at Banba for 'being weak', Gaou demands he turn himself in for punishment. IF he didn't, he'd just destroy the entire audience so as not to miss him! Luckily Riku defused the situation.
Gaou also won't break the rules, a fact the Kid used to try and beat him, by using his Quick Draw to throw the ball just before Gaou got to him, since if he wasn't holding the ball, Gaou wouldn't attack him. He did this despite knowing if he messed up once, he was finished, a point emphasized by the fact that when Gaou's pinky brushed him, leaving a large and nasty looking bruise. Sadly he did become 0.1 seconds late as Gaou's speed improved due to 'battle lust', resulting in him being crushed.
Kirihara Akaya takes this as far as the refs are willing to go. In the anime, he gets a bit nicer and less violent, but in the manga he stays just as psychotic... if even more so. It doesn't help that his team condones that, to some degree
Tachibana Kippei started out like this, but cleaned up after injuring and almost blinding his best friend.
The Higa players seem to enjoy injuring their rivals if they can. To be fair, it's done per instructions of their Sadist Teacher of a coach, but they still do it with a smile — specially Kai Yuujiro.
Double Arts. It has Sui, a female pureblood humanoid who follows the protagonist Kiri to fight the strong people who are after him. She has a slasher smile and an iron hula hoop to help as well. Oh yes, and she seems to run on canned cherries.
Sechs fits this trope. Her/his only reason for joining Alita's Team in the big ZOTT Tournament is to not miss any action which might make Alita stronger, to become stronger him/herself and to have to another fight to death with Alita after the tournament (Alita spared her/his life in their first battle). Sechs shows no interest in any political or personal events behind the ZOTT, unlike Alita who for example gets a Heroic BSOD after refusing to fight a team which stands in for children rights (which are unwanted in the dark future of that manga).
Alita herself would count for most of the series. Sure, she might fight for a cause every now and then, but is just as happy to fight just because.
Rurouni Kenshin has a few examples. The best example would be Sanosuke, who in the beginning of the series is a fighter for hire who determines his rate by how much he enjoyed the fight. After getting his ass handed to him by Kenshin, he decides to quit being a fighter for hire, but he still enjoys fighting. Then there's Shinomori Aoshi, who has a stone-cold desire for battle and to prove that he and his Quirky Miniboss Squad are the strongest around. Saitou has elements of this, as he wishes to conclude his fight with Kenshin from the Bakumatsu.
MD Geist fits this trope perfectly. He joined a group of freedom fighters who were trying to stop the military from releasing a horde of doomsdaymachines called the Death Force. After Geist kills all the bad guys, he releases the Death Force anyway so he'll still have something to fight!
Kara no Kyoukai's Shiki is a fusion of this and Sociopathic Hero. She loves killing people who are worth killing, but dislikes killing those who won't effectively fight back, as well as fighting when it's not to the death. At one point she laments something along the lines of: "I thought it would be fun to kill you, but it turns out that I simply dislike the fact that you exist, so I'll make this quick."
Benares from 3×3 Eyes is exactly this, up to the point of leaving his master unprotected in the final battle just to join the bigger fight... Although the anime is too short to give him that much personality.
Ju Ensuu from Hayate × Blade cares not for prestige or ranking, and is so obsessed with fighting her "same kind" Ayana that she throws all restrictions out the window when finally seeing the latter after a long wait. It takes some quick reflexes and two of the strongest people in school to hold her back.
Ryuuhei Sawamura doesn't fight to win, he fights to torture his opponents. Only after his fight with Ippo does he start wanting to win.
A good case can be made for Ryo Mashiba, too. He might be slightly less blood-oriented, but still more than enough to qualify.
Takeshi Sendo is the one example that isn't a sociopath, chanelling the trope into hunting down delinquents and protecting the weak instead. The guy lives to fight and in fact was brought into boxing by his trainer after street fights proved too boring. Hilariously, he even tries to explain to Ippo once that he's this trope without sounding like a dumb brute - He doesn't exactly succeed.
Saint Seiya's had a couple of these, with both Cancer Deathmask and his 18th Century equivalent Manigoldo loving to fight and then kill opponents. However, the REALLY HARDCORE Blood Knight in Lost Canvas was Scorpio Kardia, who doesn't just want to kill his opponents, but wants them to suffer at every point along the way.
Yujiro Hanma. He once fought and beat the entire American Military in Vietnam as a teenager JUST for something to do, only to walk away disgusted when America surrendered to him. Unfortunately for him he is so far beyond the other characters in strength he belongs in a higher tier series and the mangaka has had to go GO VERY far to find a potential worthy opponent in Pickle.
In fact, the entire series (by now, it has more than 600 chapters) is about Baki powering up to beat Yujiro. And Baki was on roughly the same level as, say, the most famous karate master in the world, at the beginning.
Its not just Yujiro that loves to fight, almost every fighter in the series gets a hard on for fighting. Best example of this is when a Cavemen who was frozen for 65 million years(long story) called Pickle was being held at a military base after being unfrozen. Nearly every major character in the series broke into the base to fight it.
The Heroic Tribe in Heroic Age were a race of Kaiju who apparently had little desire to do anything else but fight each other. They annihilated entire star systems in their civil war, and by the time the Golden Tribe put a stop to their fighting, only five individuals of the species remained.
Kisame is a rare mix of this and Affably Evil: he may be polite, but he also has a great love of fighting and mutilating his opponents. When he was told that he needed to capture Naruto alive, he suggested cutting off his legs so he couldn't get away and would be easier to carry. While the databooks mention who characters want to fight, his entry says "anyone". However, we do eventually find out that he's also somewhat of an Anti-Villain who's in Akatsuki primarily because he wants to see Tobi's "world of truth".
Suigetsu of Sasuke's Team Snake/Hawk has shades of this, too, given that he initially intends to kill Sasuke if he gets the chance, complains when Sasuke tells him not to kill the prisoners that get in the way while searching for Jugo, and has the backstory of being a murder prodigy who liked hacking off people's limbs before he killed them. His general motivation for all this is about a hair away from For the Evulz.
In the past, there was the entire Kaguya clan except Kimimaro. They all ended up dying out because they spontaneously decided to attack the Village Hidden in the Mist down to their last man (minus Kimimaro, who never joined in) without any strategy, just so they could kill people.
At one point, Uchiha Madara turns into this, and announces that he sees the world as mere "entertainment".
The 2nd Mizukage was one as well.
Zabuza is one as well, going at a whole horde of armed men with just a kunai in his mouth (since Kakashi disabled his arms), then (in the manga) cuts off Gato's head, despite having a few spears and swords stuck in his back.
Hisoka from Hunter × Hunter is a rather standout example of this. His sole purpose is to find the strongest opponents he can and either kill them or be killed by them. Although he has a rather narrower focus than most: once he has selected his target, he'll patiently stalk them for years, if necessary, in order to get his fight. Even if he finds other strong opponents in that time period, he'll usually pass them over in favour of continuing to stalk his chosen target. Also has the distinction of raising up, and protecting to a certain degree, young fighters he thinks might give him a good fight in the future — he calls them "unripe fruit", although there are hints of a, uhm, somewhat unhealthier interest in them as well.
Maki from Air Master is not exactly bloodthirsty and prefers to just knock her opponents out cold, but she clearly fights for the thrill of it. So do most of her major competitors in Fukamichi Rankings.
Assassin Ken Hidaka starts Weiß Kreuz as a genuinely nice guy, but eventually goes crazy and begins to enjoy killing people. At one point, after he's been decommissioned, he begs two of his friends to start assigning him missions again so that he can kill people with a clear conscience.
Himeji in Himawari!! loves fighting and things blowing up, even without an actual goal. She's on the side of the good guys, so she's reined in a little bit, but when investigating an explosion at the nearby boys' ninja school, she wishes she could've been there to see how the school blew up. Not to investigate the cause, just to see the wonderful explosion.
Both Nanoha and Signum absolutely love fighting. It's reassuring to know that both of them are good guys, but that won't stop either of them from enjoying a good fight. Adding to that is the fact that the two are generally seen as the two strongest mages of the cast. In the manga, we even get to see a flashback glimpse of a time where they actually fought each other. Let's just say that both of them had extremely over-the-top bloodthirsty looks on their faces.
Natsu from has undertones of this, though it depends on the situation. While his more serious and plot-important battles are to protect his True Companions, the rest are mostly for fun. He even shows plenty of Slasher Smile and picks fights with stronger guild members for apparently no reason other than this, and he's the most destructive member of Fairy Tail.
Fellow Dragonslayer Gajeel is just as enthusiastic about fighting, if not more so. During the S-class exam, he was actually upset that he and Levi picked the "easy" path that had no fighting. He also wasn't happy when the second part of the test didn't involve any fighting.
Azuma of the Seven Kin of Purgatory becomes Not So Stoic when facing a Worthy Opponent. He is ecstatic about having a chance to fight "Demon" Mirajane and sticks a time bomb on her sister Lisanna to force her to go all out. Azuma is noticeably upset when Mirajane cuts their fight short and sacrifices herself to save Lisanna and solemnly leaves.
Kekkaishi has Kaguro from Kokuborou who's fixated on fighting Yoshimori at his full power even killed his best friend to do so. To a lesser extent, Gagin, a fellow fighter, is elated when he gets the chance to fight strong opponents except when losing to weak humans.
Majeh from King Of Hell is this in spades, to the point where he's damned to super-hell
Her foil Sayaka, interestingly, evolves into this example from being The Cape as the weight of all that being a Magical Girl entails bears down on her psyche, mostly after Episode 6. Unlike Kyoko, she gets worse, culminating into becoming a Witch at the end of Episode 8.
Tsuchigumo from Nurarihyon No Mago, who doesn't care about joining any group in the series and only cares about fighting strong warriors. He's also The Juggernaut which make him very hard to beat.
Dilandau of Escaflowne takes war to insane levels of glee which we see especially during his fight in the Dutchy of Freid. He loves destruction, burning, torture, blood, violence, and death of any kind so war is optional but war is good too.
Asuka Langley Soryu of Neon Genesis Evangelion falls under this category- but not how you'd expect. While she appears to enjoy the heat of battle against Angels, she's not got warrior blood- she's really trying to upstage and surpass everyone else to draw attention to only her and give herself power and purpose. Unfortunately, Shinji (unintentionally) starts to outshine her, which begins to gnaw at her resolve. Worse, she's only being used on the condition that she can pilot an Eva. If she falters, she's going to be tossed aside. Unfortunately, she suffers a horrific failure in battle that leaves her in turmoil... followed by a diabolical assault on her mind.
The second Rebuild movie gives us Mari. "POINT BLANK, SHITHEAD!"
Karako, who literally attacks Ganta as soon as she meets him simply because she'd heard he was strong and wanted to fight him. There's also Minnatsuki, who gets off to seeing people in pain. Naturally, in a series like this, all three of these characters are good guys.
Kajiwara Ryou from Popcorn Avatar. He's only joined the Avatar fight because "it was fun", and loves a good scrap.
Vagabond is so full of these, that it's probably safe to say that most of the series' major fighters have some shades of this. The main character Miyamoto Musashi wanders Japan seeking fights with as many powerful opponents as he can, but he is not the series straightest example as he's also driven by othermotives. Other main character Sasaki Kojiro is maybe the series straightest example, as he absolutely relishes fighting, but unlike Musashi cares little for the glory.
#04 "Karasuba", from Sekirei. Karasuba is one of the most powerful of the Sekirei, and greatly feared by the others because of her skill with a sword and ruthlessness in battle. She is the primary enforcer for the Big Bad, having served on the Discipline Squad through all three of it's incarnations. Charged with enforcing the rules of the Sekirei Plan, she variously hunts down those that violate the rules or attempt to flee the capital and has earned a completely accurate reputation as a Hero Killer as a direct result. Known as the "Black Sekirei", the most frightening thing about her is not her love of battle — she's also an Omnicidal Maniac, and her desire to see Musubi reach her full potential is the only thing holding Karasuba in check. Most Sekirei aren't strong enough to excite her, so she's been grooming Musubi from childhood to become strong enough to provide a real challenge. They've promised to become the final two, and decide the fate of the world with their battle — if Karasuba wins, she intends to destroy it.
Ginei Morioka of Rosario + Vampire used to be like this. "No wonder they call him 'Mad Dog Morioka!'." Then San whacked him upside the head with her notebook, screamed in his ear, and basically cleared him up.
Katekyo Hitman Reborn!, Superbi Squalo is the Varia's resident swordsman and second-in-command to Xanxus. He went on a killing spree when he was young to absorb news style to perfect his own.
Accelerator tries to avoid fighting if possible, because he secretly hates hurting others. However, once he's in a fight, he turns psychotic with glee and bloodlust.
Saflee Opendays is a martial artist who enjoys challenges so she can create "pure destruction": the right amount of force to defeat an opponent, no more, no less. However, she only likes fighting in official matches, and thinks people who pick on others have no right to call themselves fighters.
In the anime Selector Infected Wixoss, Ruko Kominato's LRIG Tama, spends most of the first episode saying the word "battle" with eagerness.
Kamjin/Quamzin from Super Dimension Fortress Macross and his Expy Tehmzin from Macross Frontier are pretty good examples. Kamjin was known as "Kamjin the Ally Killer" for his reckless tactics and ended up fighting a guerilla war rather than accept peace, not because of any attachment to the old Zentradi regime but simply because he thinks peace is boring. Tehmzin tried to incite a mutiny among Zentradi NUNS personnel for pretty much the same reasons.
Played for Laughs by Ryoko Kusakabe. She shows shades of this when ordering her troops to continue firing non-stop.
Played straight with Kotori Itsuka as Efreet. She slowly starts losing control of herself and practically begs for a good fight, taunting a defeated Kurumi about how disappointing of a performance the latter put up.
Magic: The Gathering's 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 Knight Templar are the worse aspects of the 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 Guys. 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 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.
And then there's Ares, who's like Hercules but with less of a conscience. The two happen to be brothers as well.
I am sorry, Wonder Man! I cannot hear you over the sound of returning fire!
Lady Shiva, from The DCU, has been both protagonistand antagonist depending on the storyline. The only constant to her character is that her life revolves around becoming and remaining the best martial artist she possibly can — and proving it over the unconscious or dead bodies of as many other "A-List" DC martial artists she can possibly pound on. She had a brief fling in trying to be a Mentor figure for Black Canary.
For a more jolly and lovable version, see Obelix in the Astérix books. ("I do hope Asterix explains this to me later, I generally like to know why we're fighting," just before KO-ing an entire village of other Gauls in Asterix and the Cauldron.) In fact, most of the village act like this ("Hey, boys a fight!" "Come on, it'll be a change to fight each other!" leading to an all-village brawl in Asterix in Spain, which would eventually become a Running Gag).
Groo The Wanderer from the eponymous comic exhibits many of the characteristics: he will drop almost anything for a fray, and frequently chastises opponents who attempt to run away before he is finished slaying them.
In Gold Digger, the Murder Fist branch of the Shun Leep style makes its users into Blood Knights by putting them into a state of nirvana when in combat with a skilled foe. This inevitably drives them towards the Psycho for Hire category as they cease to care to exercise the control to not kill on purpose, while their skill continues to grow and grow from fighting powerful enemies.
I caught a glimpse of heaven once... Then I was cast down. Back to a world of killers. Rapists. Psychos. Perverts. A brand new evil every minute, spewed out as fast as men can think them up. A world where pitching a criminal dwarf off a skyscraper to tell his fellow scum you're back is a sane and rational act. The angels thought it would be hell for me. (said "dwarf" hits the ground with a splat) But they were wrong. Welcome Back, Frank. Says New York City.
This is only the tip of the Punisher iceberg. In Punisher: Born, his origin story from MAX imprint, it's explained that Frank Castle was born Frank Castiglione, and changed his name to Castle because there was a limit on how many tours a solder could serve in Vietnam, and he wanted to go back for a third. During this third tour, Frank starts hearing a voice in his head egging him on to greater and greater feats of violence against his enemies, and taunting him with the fact that wars end, and eventually he would have to stop. The voice is never specifically explained, but it offers Frank a "war without end, for a price. All you have to do is say yes". Frank ignores the voice until it goes away, and goes about his mission. Later, his camp is overrun by 'Cong... while another soldier has ordered a napalm air-strike on the camp itself. As the bombs fall, the entire camp is incinerated as Frank says "YES". After the battle, all the Vietcong are dead, Frank's skin is covered in third degree burns, and he is standing in the middle of the bombed out camp, wielding a M16 with the butt smashed after bludgeoning several soldiers. The next scene is him coming out of the gate at an airport stateside, months after he has healed from his injuries. He goes to hug his family, when the voice returns for the first time, and says "Hey Frank... remember that price I talked about? Enjoy your time with them while you can."
Wolverine is like this at least to some extent. The animalistic side of his psyche clearly does get pleasure from violence.
The Ultimate version of Wolverine seems to be this way or at least in Ultimate Wolverine vs Hulk. In it he's offered a chance to save a village in a far off country from the Hulk; he doesn't care about any of the people, he just wants a thrill from a fight.
Meanwhile, Sabretooth IS this. Easily the most bloodthirsty character in the MU besides maybe Bullseye and Carnage, he lives for nothing but the opportunity to be able to slaughter anything that it's practical to slaughter, and he'll usually also bag a few other prizes.
Juggernaut is this too. He is compelled to revel in wanton destruction of his own making by the powers of Cyttorak that fuel his strength. In fact, if the Juggernaut isn't engaging in indiscriminate violence for the sake of indiscriminate violence, he actually gets weaker.
In Usagi Yojimbo, Nakamura Koji is a swordfighter who goes around looking for worthy opponents to duel with. There are other such characters in the series too.
TheMidnighter from the Wildstorm series The Authority as he's about to destroy a city by ramming it with a 30 mile wide space ship aimed directly at the Villain of the Week:
Overlord never cared about rank, glory, or the advancement of the Decepticon cause... he was happy as long as he had the opportunity to fight and slaughter as many Autobots and bystanders as he could. Megatron, however, wasn't happy with that — upstart subordinates had given him too much experience with Chronic Backstabbing Disorder to take it on faith that someone with that much power wouldn't make a power grab. So when Megatron tried to tighten the leash and take more control over Overlord's actions, Overlord re-purposed Garrus-9 into a planetwide spectacle of violence and chaos to provoke Megatron into the one fight that Overlord has always wanted. He has a Villainous Breakdown and surrenders when he finds out Megatron is (apparently) dead.
In the Marvel Transformers comics, Bludgeon probably qualifies. He talks about a grand dream for the Decepticons conquering the universe but when they actually conquer a world... he's bored out of his mind and wondering when the Autobots are going to show up to stop them. And again when he invades planet Earth, he's bored out of his skull (no pun intended) because Optimus Prime doesn't show up to fight him like he hoped he would. One suspects that if there were no Autobots he really wouldn't give a damn about the Decepticons or their plans to take over the world.
Mongul II is merely one of these at his very best. The arrogant, fight-loving asshole side, however, is almost always supplemented with some of the most disgusting behavior in the DCU. He bit off more than he could chew, however, and holy shit did Sinestro make him pay for it.
The one-shot "Mogo Doesn't Socialize" gives us a bounty hunter by the name of Bolphunga the Unrelenting, who hunts down the titular Green Lantern for the fun of it. He ends up... well, relenting... on realizing that Mogo is a planet.
Batman shows Blood Knight tendencies at times. He often tries to make himself not enjoy the violence he inflicts upon criminals, but some pleasure does seep through as this quote from War Crimes shows:
Batman: Still, doing it this way does have its compensations. My fists fit so nicely into their guts. And impact meat and bone with perfectly satisfying thumps.
The Comedian of Watchmen gleefully admits that he is this trope. It's at least partially a product of his worldview, as he seems to act this way mostly because he acts the way he feels the world actually is.
In Sin City, Marv admits that he loves a good fight. Miho apparently does as well.
Deadshot, oh so much. Lampshaded by his then-lover Jeanette when she says that one of her previous husbands was "A mad dog killer who pretended it was for money" and goes on to say that he was probably a bit LESS single minded than Deadshot.
Catman and Scandal are also very much this trope, and King Shark certainly skirts it as well.
The Thunderbolts once featured two of these as members: Scourge, formerly Nuke, a battle-crazed lunatic whose worst nightmare is a world without war, and Mr. X, whose empathic powers cause him to experience incredible bliss every time he kills. Mr. X reveled in the chance to go to Asgard during the Siege event — he wanted to prove he could kill a god. He could.
Avengers arch-foe Kang the Conqueror. He was a native of a peaceful age in humanity's future. Kang thought peace was boring, so he donned a futuristic combat suit and used Time Travel to become a conqueror of all time and space.
Deadpool: He punched Kitty Pryde to try and get Wolverine mad enough to fight him and was extremely happy when the claws came out, yelling "Snikt me! Snikt me!"
"Yay, now is fighty time, fighty time, blood blood blood!"
Warren Griffith of the Creature Commandos was a werewolf. Though he's a sheepish coward in human form, his wolf form carries with it a primal bloodlust that is never sated. He's always looking forward to the next battle, and never satisfied when it ends.
Like his video game counterpart, the titular Sonic the Hedgehog is this, though for a completely different reason. There's also E-123 Omega, who has gone so far as to unload his payload on a Physical God and complain when he still had ammo to hit him with. He's even fallen in love (or close to it) with Blaze the Cat because of her own actions!
Sonic The Comic's Sonic fits this, he gets bored and restless when there's no new challenge or threat, and will often deliberately go seeking one out.
In Weaver Nine 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 Leviathan appropriately (though he does decide to fight, in the end).
In 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.
The combat-addicted skahs wizards and warriors of Baravada in With Strings Attached. 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 Batman Gambit, Ringo spreads the word that there are monsters in the distant Ghost City 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 More Than Human has two blood knights: Butch and Buttercup. This personality trait is actually a major plot point that connects the two together and allows them to bond.
Garrus Vakarian in Mass Effect Interregnum. 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.
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 releasesTitan, knowing that the latter shares his beliefs, and will enable him to fight and kill as many ponies as is needed to enforce Titan's rule of Equestria.
Ace Combat The Equestrian War 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 Ax-Crazy for most of the fic, he shows a bit of honor when Fluttershydefeats him, managing to congratulate her on a "good kill" before he dies.
Agent Diamond, from Akatsuki Kitten Phoenix Corporation Overhaul, is halfway between this and completely Ax-Crazy. 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.
In A Fathers Wrath, Lu Xiaong who refers to himself as a Warrior instead of a ninja is this as even though he sides with 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.
The Dragonborn in the Cross Over fic, 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 eating tasty, detestable Thalmor in her Werewolf form. But when she 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 DougRattmann.
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 someone she cares about is threatened. In which case you're looking at a berserker.
A Growing Affection 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.
Phoenix from Friendship Is Showtime, 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 "Dragonshy", solely to get Haru to fight him. After winning the first fight easily, he even refuses to fight Haru again until provoked significantly. After being beaten by Flame Dragon Style, he becomes obsessed with fighting Haru.
Iron Will in 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 Diaries of a Madman, Luna is very fond of battle, which doesn't gel well with the fact that she's not entirely sane to begin with.
In All The Way Back, 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 Fish Out of Temporal Water feel useful again, in part because she simply enjoys battle.
In Mega Man: Defender of the Human Race, Punk seems to be this, and Bassdefinitely 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 Angels of the Storm is an ancient Titan built by 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.
Kitsune no Ken: Fist of the Fox: 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.
The Omega Chronicles has a few examples of this, but the biggest one of them all? 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.
The titular villain of 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. 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 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.
Luo-Long from Sword of the Stranger 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.
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.
Films — Live-Action
Kurgan from Highlander loved to fight and kill and was a sadist to boot.
Stephen the Irish, in Braveheart, who seems more interested in killing Englishmen than winning wars or freedom.
Colonel Hessler, the panzer commander in the 1965 film Battle of the Bulge. For him life is to be spent in the turret of a tank, fighting until death takes you.
Tallahassee from 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 cackling maniacally while he's doing it too.
Emil Blonsky from the 2008 The Incredible Hulk: 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 Super Soldier and an outright abomination (no pun intended) to be able to have a "real fight".
The Avengers: The Hulk seems to exist to fight. He smirks when commanded to "smash."
Brad Whitaker, chief villain of The Living Daylights 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.
Battle Royale brought out true intentions of students who really gained pleasure from killing their peers.
Deathwatch 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 WW1 trench.
The predator aliens from the Predator series. They use their advanced technology to travel around the galaxy and hunt the most dangerous game. When they find a Worthy Opponent, they even cast aside their high-tech weapons on occasion to even the odds and make things more entertaining. In 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 The Lord of the Rings: fearless, Bad Ass Dwarf, with shades of Violent Glaswegian 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 Large Ham John Rhys-Davies.
Mad Dog on in The Raid loves fist-fighting. Twice he disarms himself and allows his enemies a fair chance to defeat him in unarmed combat.
At the start, 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.
Elysium: Kruger and his squad-mates Drakey and Crowe.
In X-Men Origins: Wolverine, 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 Guardians of the Galaxy; 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 Adam R. Brown's Astral Dawn series, Tyr derives pleasure from battle, death and destruction. The only reason he's involved in the plot to conquer Heaven with Set and Devlyn is because it will give him more opportunities to fight and kill.
This seems to be the attitude of many of the member of the Clave in Mortal Instruments, particularly Jace
Lord Borel, in Roger Zelazny's The Chronicles of Amber, has as his main goal in life to outfight either Eric, Corwin, or Benedict, some of the other best swordsmen in that universe. Corwin shows him that it's not all about bladework.
The "Warriors at the End of Time" in some of Michael Moorcock's fantasy novels (particularly The Dragon in the Sword) are said to be powerful soldiers who loved fighting for its own sake, and were then damned to fight on behalf of the Cosmic Balance for all eternity.
Keeping in step with the trope's title, Radha of Keld in Magic: The Gathering'sTime Spiral card set and novels was intent on little other than fighting, at first spurning the world-saving efforts of Teferi and his companions... at least until he gave her the ability to kick even more ass than she could previously. She softens a bit as she grows to accept the necessity of helping Teferi, but she's always a hard-bitten warrior first and foremost. To wit:
"I hope to have such a death - lying in triumph upon the broken bodies of those who slew me."
To be fair, all Keldons are like this. Look down in the Tabletop games section.
In several of the later Animorphs books she narrated, Rachel expressed fear that she might be slowly becoming like this. Too bad she was this soon after acquiring her grizzly bear form. Seriously. She and Zaraki up top would make a lovely couple.
In The Dresden Files novel Cold Days, Harry finds that the Winter Mantle has a very strong drive for this. In fact, after a major battle, Karrin says he had an erection throughout the battle. Suffice it to say, the change very much scares the person.
The Silastic Armourfiends of Striterax in The Hitchhiker's Guide to the Galaxy took this to extremes since if one was locked in a room by himself he would eventually beat himself up just for something to do.
David Eddings' The Elenium and Tamuli trilogies had the Atans, a race who bred themselves as fighters— but did so a little too well, giving them hair-trigger violent reflexes, so that their society was plunged into endless war until they voluntarily pledged their entire race to slavery to the peaceful Tamuli, who as a result gained an unconquerable empire by default. Every Atan believes that they have to have a master to hold them back, or they go on killing sprees.
The Nac Mac Feegle in the novels are clans of "pictsies" who live primarily for drinking, fighting, and stealing, preferably at the same time. Each clan also has a Gonagle or Warrior Poet, though in this case the poetry itself is a weapon of war. Taken to extreme when it's explained that a Feegle left all by himself may very well kick himself in the nose just to keep himself occupied.
There's also the D'regs, a nomadic tribe from the desert regions of Klatch characterized by their love of fighting. It's said the D'reg word for "stranger" is the same as their word for "target". There is one scene in Jingo where someone has a hard time translating the concept of "fighting for freedom", since in the D'reg language they are the same word. It's also mentioned that when the nations of Klatch and Hersheba drew an arbitrary border across the D'Regs home desert, they leapt on this new division of nationality as a wonderful excuse to start fighting each other, too.
Strong Belwas, a former pit fighter, delights in showing off his prowess to the point that he always allows his opponents to get one slash in before he kills them.
House Clegane has spawned two—Sandor Clegane lives for little other than fighting and believes that "killing is the sweetest thing there is", and he's the good brother.
Gregor Clegane managed to make a career out of raping and murdering his way across Westeros, referred to as "foraging" in polite conversation.
The Dothraki. They consider any event (like a wedding) with less than three deaths a dull affair.
The Smiling Knight was an Ax-Crazy Blood Knight who wanted to fight a member of the Kingsguard. He got his wish and met his end when he fought Arthur Dayne, the Sword of the Morning. Jaime witnessed the fight in his youth and considered it one of the best moments of his life. In a moment of self-reflection in the present, Jaime wonders how the boy who wanted to become the Sword of the Morning became the Smiling Knight instead.
Robert Baratheon, before he was King he was warrior who lived to fight, and when he took the Iron Throne he grew bored of managing the realm. He would have left the throne, and sailed to the Free Cities to be a sellsword. The only thing stopping him from doing it is his (bastard) son Joffrey taking the throne.
The Heroes by Joe Abercrombie has two big ones: Bremer Dan Gorst of the Union's entire existence is fighting to the point where he compares fighting one-on-one with another enemy to romantic affection. The other one is Whirrun of Bligh who actually faces off against the former. Gorst is extremely disappointed when it ends prematurely.
Mace Windu struggles with this in the novel Shatterpoint. You don't get to be second-in-command of the Jedi Order by going to town on everyone with a lightsaber, and Windu loves the stability the Republic provides, but he likes fighting anyway. He develops the dangerous lightsaber style known as Vaapad as a way to channel this aggression for good purposes.
The Yuuzhan Vong warriors live for combat, justified as they are raised in a caste system, and they live solely to fight and kill.
Jacen Solo AKA Darth Caedus is a lead from the front, get-stuck-in kind of fighter. It catches up with him in the end however, as the intensifying pace of battles leaves him increasingly debilitated.
Greystone Valley's villain Baelan is a ruthless warlord who has grown frustrated with the fact that he's trapped in a world with nothing worth conquering. The entirety of his villainous plan is focused around opening up infinite other worlds where he can do battle.
99.99% of the Drow race from R.A. Salvatore's Drizzt novels (and Dungeon & Dragons in general) are Blood Knights. They are born, raised, and die (usually before anything close to the natural end of their 700+ year lifespan) in a perpetual power struggle featuring hundreds of noble houses. And ninety nine percent of them (with the exception of Drizzt, his father, and a couple others from other scenarios, and they partially meet this tropes standards in the sense that although they don't kill for fun they get fun from killing), live for it and enjoy every second of their blood-soaked lives. Even Drizzt is a Blood Knight to a certain, less evil extent: in one of the long introspective commentaries placed at the opening of each act, Drizzt comes to realize that he is a "creature of action": he can only be truly content if he has his swords strapped to his waist and is going somewhere, though this is more of a thirst for adventure than a true hunger for battle. He has, however, been known for bouts of berserker rage when the right buttons are pushed. Drizzt's rage does not hinder his incredible focus in the slightest, and makes him hundreds of times more dangerous to even disciplined foes.
Speaking of R.A. Salvatore's novels: Artemis Entreri. The most Blood Knighty Blood Knight of all Blood Knights!
The most wild battle rager Thibbledorf Pwent! He is a blood knight personified!
All the Brothers in J.R. Ward's Black Dagger Brotherhood series fit this trope. They're elite vampire warriors bred to protect the vampire race from vampire hunters and they love their job. All of them, but especially Zsadist, live for fighting and killing — until they meet a good woman because Love Redeems.
In Alan Dean Foster's The Damned novels, all of humanity were Blood Knights. It turns out that the humans only fought each other because they lacked an external enemy to fight. When such an enemy presented itself...
Kage in Gav Thorpe's Warhammer 40,000 The Last Chancers. At the end of 13th Legion, he receives a pardon, resolves to stay in the forces outside the penal legion, and shortly thereafter loses it by brawling. In Kill Team, he is told that he used up his last chance and will never be pardoned again, and he can cope, realizing that he would have ended up fighting again.
Conan the Barbarian is a straight-up example of this trope. He comes from a culture of northern barbarians who consider the thrill of battle to be one of the only true joys in life.
The Valerians of the Lensman universe are this - seven foot tall denizens of a three-grav world, whose favourite weapon is the space-axe (because personal shields increase their resistance with the velocity of the impacting body), whose ultimate goal is a warrior's death, and for whom a peaceful death is a disgrace. As Smith himself says: "No bifurcate race, and very few others, have ever willingly faced the Valerians in hand-to-hand combat." Fortunately they are the good guys, and more fortunately they are very good at recognising authority (in terms of who to kill and when to stop).
The Rohirrim in The Lord of the Rings, And then all the host of Rohan burst into song, and they sang as they slew, for the joy of battle was upon them. Not to mention when they later charge at the, far numerically superior, enemy screaming "Death!".
The warships and militarised drones of The Culture all exhibit this to some extent. They have exceptional self control but when they feel that circumstances are such that they can let themselves off the leash they will utterly annihilate their opponents and have enormous fun doing so. In at least a couple of cases, they've been known to keep very high resolution recordings of the battles they're involved in that they seem to get an almost sexual thrill from watching later.
Trapped on Draconica: All Leondians love fighting. This means their Prince, Kalak, will always choose fighting over any other solution.
Wild Cards. Billy "Carnifex" Ray is this, displaying increased strength, speed and healing abilities to get him back in the fight. This is a man who once pursued an opponent with half of his face cut off, and seems to revel in combat. Considering that he's an Expy of Wolverine, it's not surprising.
Tash's first clone in Galaxy of Fear, is this as well as being Drunk on the Dark Side. So are the others, but she's specifically happy at the chance to kill Tash right then and there.
In John Milton's Paradise Lost, when the devils take council, Moloc is the first to speak and urges immediate and outright attack.
Sculley from 1356, who is very upset to realise he hasn't killed anyone in at least a month.
In Musashi, the titular character and his Foil, Sasaki Kojiro are both this. However, Musashi fights in order to test himself and become a master, while Kojiro has a sadistic streak, and fights to promote his name.
The trollocs of The Wheel of Time are what happens when Blood Knight meets Dirty Coward. They're extremely bloodthirsty and love to fight, but really don't seem psychologically equipped to deal with defeat. So when they're winning, they're inhumanly aggressive and brutal, and when they're losing, their morale breaks almost instantly and they route easily. Whip-wielding Myrddraal ensure that no matter which mode they're in, trolloc forces remain pointed at the enemy.
Most of the Career tributes in The Hunger Games, who are trained from childhood to fight and to treat the Games like a game and an honorable tournament. They usually proudly volunteer at the reapings, something most kids from the lesser districts would never consider doing.
Mayor Prentiss. When he witnesses an army vastly superior to his own descending upon his city with the intention of killing him in retribution for a genocide that he committed for the sole purpose of instigating this war his reaction is to grin with joy and utter: "War. At last."
In Riesel Tales: Two Hunters, one of the two titular hunters, Runge Margavo, is more than happy to snatch up an assassination job and repaint the floor with someone's gray matter, and he's been described as someone who participates in bar fights with apparent regularity.
T. Sean Collins, the mercenary, in World War Z. He realizes that he is "addicted to murder" and will eventually either kill himself when he runs out of zombies to kill or face losing control and slaughtering actual people.
Skeeter Traps from Chronicles Of Magic is a ten year-old version of this. While one of the good guys, she enjoys fighting and is naturally prone to violence.
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."
Dean Winchester in 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.
Kate Argent, in Teen Wolf, who is a Werewolf Hunter.
Bisque, a one-off villain with a history to the mentor 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.
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."
"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."
Blackadder: King Richard IV (played by 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 Rousing Speech before the Battle of Bosworth Field:
Richard IV: Let blood, blood, BLOOD be your motto. Slit their gizzards..
Langston's father on CSI: Crime Scene Investigation 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 genetic trait, but nonetheless uses the story and the fact that he became a doctor to assure the son of an infamous Serial Killer that In the Blood doesn't exist.
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.
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 "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!
Phantom Zone escapee Titan is an alien Super Soldier and Proud Warrior Race Guy, portrayed by 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 Worthy Opponent in Clark. Think of him as a Nigh Invulnerable wrestler with an attitude problem and you've got him.
All "true" Klingons are this. Even the good ones still love a good scrap.
Star Trek: Deep Space Nine provides an example in the least expected place: Leck, a 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 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".
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 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 Television Without Pity to jokingly refer to her as "Raige". Fittingly, she wound up becoming the Goddess of War in the Titans two-parter.
Golgotha from Noob gets bored if she has to do a quest without any battles and frustrated if battles happen but are too short.
The narrator from David Bowie'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 Manowar, including "Black Wind, Fire And Steel."
"Eye of the Tiger" by Survivor is a blood knight anthem, especially the chorus. "It's the thrill of the fight!"
"Iron" by Within Temptation describes one of these. "You can't live without the fire, it's the heat that makes you strong".
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 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 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 The Berserker 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, and for the eventual warrior's death. Dying outside of the battlefield would result in a Fate Worse than Death for any berserker: not getting in to Valhalla.
The Morrígan from Celtic Mythology 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. Poor Communication Kills? No, she's just that good.
The Asura of Hindu 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 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.
The Yazi, one of the nine offspring of the Chinese dragon. They love fighting and killing and they are often depicted on the handles of weapons.
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 Catch Phrase sums it all up: "My name is Finlay, and I love to fight!"
CHIKARA's Eddie Kingston turned into this after his Face-Heel Turn 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", Sheamus (who had lost the 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 The Big Show a Worthy Opponent and said he was on pins and needles waiting for another swing at the world title.
Many characters in This Is War, ranging from simply enjoying combat, to enjoying the feeling of winning a fight, to grimly enjoying killing a particular species, it's all there.
Both the Warhammer and the Warhammer 40,000 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 — 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 Depending on the Writer. Those trying to make Chaos a bit less of a mustache-twirling For the Evulz 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 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 Church Militant, the fact the many in-universe statements and preaches seem to consider warring against their enemies to be a way of worshipping the God Emperor, 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.
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.
The Elves of the Valaes Tairn in the Eberron setting.
The Battleragers in the Forgotten Realms 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 those who oppose his dogma real foes worthy of a conflict.
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 Crapsack World of pre-Ragnarok Midgard in Fate of the Norns: Ragnarok 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.
GURPS gives us the bloodlust disadvantage, and with it rules to handle playing a Blood Knight character.
The Adamantine Arrows of Mage: The Awakening 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.
Werewolf: The Forsaken 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.
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.
BattleTech the 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, "outdated" Clan warriors past 50 years old are reassigned to Solahma units, given an outdated assault rifle, and sent out as Cannon Fodder to distract battlearmor and battlemechs.
Tybalt from Romeo and Juliet 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.
Sonic the Hedgehog can be considered one, as he's "the guy who loves adventure." In other words, he loves the thrill of cheating death many times over and facing impossible odds for the adrenaline rush. This is why he has Dr. Eggman as his nemesis, because Sonic and his addiction to combat and danger wouldn't be complete without that overweight mad-scientist and his robot-armies feeding as much of his suicidal tendencies as possible.
Karel is a wandering, half-crazed swordsman whose only goal is to seek out the most powerful fighters on the continent and cut them into tiny little pieces. He joins the protagonists because he's curious as to whether they'll help him find stronger opponents, killed his parents, threatens to kill both his younger sister Karla and his apprentice Guy if they ever grow strong enough to make for a decent fight, and bribes Dart the pirate for gossip about the toughest fighters in the land, only to discover he's already beaten them all. This characterization actually came about as a result of Karel's appearance in the previous game, Sword of Seals (which follows Blazing Sword chronologically). The designers wanted the young Karel to contrast the saintly Warrior Poet personality he sported in the latter game as much as possible. It's implied that he was mellowed by the death of Karla to illness during the timeskip between the two games — he finally found an opponent he couldn't defeat with strength alone.
He more or less flat-out states this with his dying words. "Death cannot be bested with a sword... My skills are not yet honed to such a level. I should take my leave of this battle."
This trope is frequently used by other characters in the series (mostly Fighters and Myrmidons), to a lesser degree. Karel's future brother-in-law Bartre, also from Blazing Sword, plays the trope mostly for comedy. His daughter Fir also uses it, although she's a little more stable than both her father and her uncle. Other examples include Marisa the Crimson Flash from Sacred Stones, Stefan from Path of Radiance, and several boss characters.
Karla seemed to be a much less extreme version than her brother, and somewhat less than Barte or Fir. While she isn't obsessed with killing like Karel is, she has dedicated her life to swordsmanship and seems to get some enjoyment out of fighting.
Another example from Sacred Stones is Valter, who wants to kill Eirika and Ephraim solely for the thrill of fighting them. However, he focuses on Eirika quite a lot.
And then there's Skrimir, from Radiant Dawn. If he doesn't qualify, no one does.
Skrimir: Run down all who get in your way! Make your path of blood and bone! Advance! Advance! Advance!
Skrimir: Bah! Is that it? I still crave blood! Find me more humans to kill!
The Black Knight aka General Zelgius. Aside from his loyalty to Sephiran, his primary goal in life is to test his sword against worthy opponents.
Henry from Fire Emblem Awakening joins Chrom's army instead of his own nation's simply on the basis that the latter has far more soldiers, meaning he'd have more people to fight that way.
In one of the numerous mods for Medieval II Total War, amongst other new factions, you can play as the Principality of Wallachia. Yes, the same Wallachia that the infamous Vlad Tepes came from. And while you can turn any faction into an Evil Army of Blood Knights, Wallachia is almost this by default. Their peasants, the supposed Cannon Fodder, wield axes, have unusually high morale, and may charge without orders. Their description also notes "they have a taste for fighting". The most awesome peasants in the game.
The Scots in the regular version of Medieval II manage to come pretty close, though. Most of the other factions have the bog-standard peasants. The Scottish equivalent are Highland Rabble: unwashed, kilt-wearing, and extremely fast-moving painted Highlanders wielding big knives. That's before you factor in the regular Highlanders, who carry axes and shields, and the much nastier Highland Nobles, who are armed with giant claymores. And all of these Highlanders are fast-moving infantry who work best blindly rushing the enemy. The Scots are an infantry army built to CHAAAAAARGE!
Blood Knight tendencies are an actual trait that generals can pick up, usually as a direct result of personally charging their bodyguards into the fray. It starts with the "Fine With Blood" trait, which gives a bonus to dread, Command, and Morale. It progresses to the "Sanguinary" trait, explicitly describing the general as actively wanting to charge into combat and kill people, increasing Dread and Command, but unnerving the troops and causing a small penalty to Morale. The last level of the trait is "Bloodthirsty", in which the general is so balls-out demanding for blood and violence that while he gets a big boost to Dread, he suffers a penalty to Command and the troops are so terrified of him that they suffer a huge Morale penalty.
An unusually calm version of this trope is Ryu. He'll only fight those who are willing, and (save for the "Evil Ryu" arc) conducts each fight respectfully and never to the death. Nonetheless, he's not in the tournament for the glory, just the next fight. The flip side of the coin is Akuma, who seems to exist only to fight and grow stronger, and will explore Dangerous Forbidden Techniques, kill his opponents, and generally do anything he can do in order to fight and gain power. The similarities in their motivations serves as a source of dramatic tension between them, as Ryu shows a considerable level of angst over whether he'll eventually end up like Akuma. There is at least one adaptation, Ryu Final, where Ryu and Akuma's path are explored down to their final destination and outcome. It is first implied, then explicitly stated, that the path of the True Martial artist is a journey of self-betterment, with each fight (hopefully) making both warriors learn and grow as people, and where the ultimate outcome is to realize the futility of the fight, next to nurturing and protecting the next generations to come. More particularly, Akuma's search for power and willing submission to the Satsui no Hadou is done entirely for the benefit of Ryu, so the latter would have the guidance needed to overcome it.
Canderous is a perfect example of this trope. (He does eventually decide he needs some kind of cause to fight for, but doesn't seem to care very much what that cause is.) In fact, most of the Mandalorians seem to be that way.
The Mandalorians aren't the worst, though. In one level you meet an Iridorian whose worldview makes the Mandalorians look like the Care Bears. Like he said:
Honor comes from slaying your opponent, and the true reward of any job is the taste of your foe's drying blood on your tongue.
Dante from Devil May Cry is a bit of a Blood Knight, but at least everything he kills deserves to die, him being a demon hunter. Unlike some Blood Knights, Dante is not obsessed with fighting; he doesn't go out and kill for fun, but fighting is such a part of his life that he makes it fun. In fact, the point of the combat isn't to kill the enemy so much as to kill them stylishly, which he demonstrates constantly in cutscenes.
Dante: So bring it on! I love this. This is what I live for. And I'm absolutely CRAZY about it!
Rugal Berstein, Gato, and Shen Woo from The King of Fighters. To be more specific about Rugal, he holds the tournament in the first game because he was BORED about not having any strong enemies. As for the others, Gato has left everything including his little sister to dedicate himself to fighting, and Shen is extremely boisterous and always ready for a fight. For a female example, look no further than Rugal's ex-Sexy Secretary and membress of the Orochi clan, Vice. Leona can come up as such sometimes, but she's more of a Sugar and Ice girl.
Kratos from the God of War series delves into this at varying times in his life. It definitely applies in his backstory in the first game, as well as the interim between the first and second. During the games he seems to have a definite cause he's fighting for, but between them, he's more than happy to just go out and kill whatever the gods point him at.
Zegai in Suikoden V is a straighter example of this.
Kelgar Ironfist from Neverwinter Nights 2 loves nothing more than beating the crap out of things, and seeks to join the Monks of the Even-Handed so he can beat even more crap out of things. Try to explain to him that Monks Don't Work That Way and he'll completely miss the point. Interestingly, if/when he actually earns membership in the monk order, he becomes far less of a Blood Knight. So much so that in the Expansion Pack, Storm of Zehir, he is actually the steward of Crossroad Keep, and refuses to join you in fighting bad guys because he knows he has a more important duty.
A Dance with Rogues has several companions that exhibit these traits - Vico and the siblings Bran and Norah. While Norah's love for battle is downplayed and only mentioned in passing, Vico and Bran both revel in fighting, albeit for different reasons, since the two are counterparts. Vico is the more violent one, who loves fighting and killing his opponents, as well as butchering people and creatures from other races just for fun. Bran is a barbarian and has been taught to be a warrior since childhood, but he enjoys only the fighting aspect of battle and strongly dislikes picking fights with and killing non-hostile people for no good reason, and is willing to let his opponent go at the end of the fight. His greatest pleasure comes from battling monsters and extremely hostile and dangerous creatures, like orcs, dragons, demons and undead.
Volf is one of the Four Greater Fiends the hero must slay in Ninja Gaiden II. He takes the form of a massive, four-armed werewolf with tribal tattoos and a massive scythe, and commands an army of lycanthropic demons. He is also obsessed with causing violent injury to fleshy things. The scene that introduces him shows him sitting on a throne watching as an army of his demons rips a (strangely out-of-place) gladiator to shreds, and then, with the simple comment, "This bores me," annihilates half of his own subordinates with razor wind out of sheer boredom. Following this, he tells his army to go out and find him a worthy adversary, essentially planning to sacrifice his entire army of werewolves to see if anyone can make it to him. Ryu just happens to fit that particular bill, killing Volf and taking his scythe after ripping through his entire werewolf army. However, Volf's battle lust doesn't stop there. In the final level of the game, Volf attacks Ryu in the Underworld after Ryu enters to prevent the revival of the Archfiend. Naturally, he is subsequently slaughtered, for good this time, but talk about persistence.
The Channel 4 News Team: They're usually rather polite to other survivors though, focusing on zombies, and are responsible for many of the notable survivor victories in the game, so they may count as Proud Warrior Race Guys instead.
Many PKer groups have this as their schtick as well.
The zombies. Nearly every social zombie player group can sum up their tactics as "Go find the nearest large group of survivors and start the party," the only divisions being what is considered fair play on the "finding-survivors" part. Mass zombie movements ("tours") are almost the same as an Ork Waaagh in intent, tactics, and the habit of leaving a lot of new zombies in their wake. And they seem very pleased at their worthy foes when a mall or important building manages to outlast a zombie siege, honoring it by making sure it's a major stop on the next "tour".
Mitsurugi. While he initially seeks Soul Edge in the hopes that the sword will make him powerful enough to defeat a rifle, he ends up strong enough to do so anyway, so he just keeps fighting for the sake of fighting. Even in his Soulcalibur IV ending, when offered the option to absorb the power of the Big Bad, he ignores it, because he says: "I don't need it." In his backstory, it's revealed that Mitsurugi used to deliberately offer his services to vastly outnumbered armies so that he could fight as many foes as possible.
Algol as well: "Fighting is my all. It is my existence!" Same for Olcadan and bonus character Shura.
Haohmaru from Samurai Shodown, who, just like Mitsurugi, is just on the scene looking for a good fight. Almost everyone he encounters, especially bosses, will get this kind of response from him: "Hey, you gotta be strong, huh? All right, this is gonna be a good fight!" He's a bit less extreme than Mitsurugi in that he takes on all comers but doesn't actively seek out massive conflicts (for the most part, he doesn't have to), and he just wants to be the strongest fighter around. If Amakusa gets flattened by a boulder, well, dead is dead. Definitely on the heroic side of the equation (he couldn't have formed working relationships with the likes of Nakoruru and Charlotte otherwise), whereas Mitsurugi is resoundingly amoral.
Quake III: Arena states that the gods, wanting entertainment, have put you and these others in the arena, and made you all immortal so that even death would not release you from endless fighting.
Bass leans this way. He's largely unconcerned with his creator's (Dr. Wily's) goals and fears, and in the arcade games and Mega Man & Bass, he'll stand against Wily if Wily annoys him enough. His primary goal is simply proving he's the strongest robot around.
Three out of the Four Guardians in Mega Man Zero are like this. Upon discovering that Zero is a Worthy Opponent, they tend to shirk their other duties in favour of fighting him and rapidly escalate the whole business to Foe Yay levels.
Plenty of Mavericks and hostile Reploids that you fight say they were looking forward to fighting the protagonists. Even when the world is ending all around them. Magma Dragoon from Mega Man X4 is the best example, as he caused the plot of the game, and the resulting deaths of millions, just to fight the protagonists.
Axl from the X series is equal parts this and Tagalong Kid. When asked why he fights, his most common answer is that he enjoys it. The fact that he's fighting for justice is largely a fringe bonus (although X7 explicitly shows that he doesn't enjoy being an asshat).
Omega-Xis in Mega Man Star Force can be like this. He wants nothing more than to cut loose and go buck-wild on assorted viruses, villains, and so forth, and his default response when presented with any piece of human technology he doesn't immediately recognize is to ask "Is it a weapon?" In the backstory, the Zerker tribe from 2 are described as "living only for battle".
He seems to have an aversion to killing women. Though perhaps he just hates to see some good lechery-fodder go to waste.
He also seems to be averse to killing anyone who fights with honor and/or proves to be a Worthy Opponent.
Actually, most of the assassins in the series seem to be Blood Knights. Death Metal, Dr. Peace, Destroyman, Holly Summers, Harvey Moiseiwitsch Volodarskii, Speed Buster, Bad Girl, Matt Helms, Cole Walsh, Ryuji, Margaret Moonlight and possibly even Henry seem to greatly enjoy battle and killing to perverse ends.
In Tales of Vesperia, Yuri seems to be happiest when he's in a good fight and says that he enjoys the "raw challenge" of fighting a tough opponent, and the only time Judith's excitement level rises above "sedated" is in battle. Flynn, who is normally soft-spoken and mellow, becomes very energetic when fighting (lampshaded by Rita in the PS3 version). Zagi is the standard villainous version who becomes obsessed with Yuri because he is the only opponent that forces him to use his full potential. There's also Tison, who unlike most of the Hunting Blades fights monsters more for the thrill of battle rather then a personal vendetta.
Adell from the Disgaea series qualifies as well. He's more of the cheerful sort that only kills when he has to tough (though his chief target certainly deserves it).
Black Whirlwind from Jade Empire most definitely counts.
Black Whirlwind: I won't stop until I'm ankle deep in blood, standing on my head!
Black Whirlwind (while waiting for an army to arrive): Why wait? We should just charge them now
Red Arremer, also known as Red Blaze or Firebrand, in Gargoyles Quest and Demon's Crest.
Kirby: The only wish of Meta Knight is to become stronger and fight a worthy opponent.
In the Anime, he also states that he's encouraging Kirby to fight monsters because his nature is too kind to seek out opponents on his own.
A light case of this: As of Touhou: Undefined Fantastic Object, Sanae appears to be really enjoying the duty of "youkai extermination" (fighting youkai to keep them from bothering humans). Some see it as sadism that ruins her "good girl" image, while others think she's just having fun fighting.
Touhou is flooded with this. It is the only reason for the bosses of the first two to four stages to even be fighting the heroines (who are little better, going by the dialogue). In the fighting games, it's the only reason anyone but the Big Bad fights.
Big Boss originally founded Outer Heaven because he only ever felt truly alive when he was on the battlefield, and wanted to create his own independent warrior nation of mercenaries that would participate in conflicts all over the world. It is not so much that Big Boss wanted a world of eternal conflict; in his mind soldiers would always be needed and wars will always be fought so long as there are people. He simply wanted to create a system where soldiers are respected for their talents and not manipulated by corrupt political forces in the government as he had been (as well as The Boss had been). True warriors like them have no allegiances to nations or ideologies; war is their home and what they believe in.
Big Boss explains to Snake his reasoning for Outer Heaven; not only does he enjoy conflict but he has fought in so many wars (his career as a soldier started in 1950 during the Korean War so by 1999, he had been a soldier for almost 50 years) that he has spent the majority of his life on a battlefield of some sort and civilian life is foreign and intolerable (he mentioned at one point that, if a soldier like himself who was living a civilian life was even lucky, he'd get an interview from a two-bit tabloid, at best). Big Boss needs war; a world without conflict is absolutely inconceivable to his very existence. He knew from the moment he had a taste of war and had awoken the warrior spirit within he could never go back (an optional Portable Ops conversation has Big Boss tell how he tried to put the warrior spirit to rest, he tried to be a combat instructor or a hunter, but despite his efforts, ended up back on the battlefield again). Big Boss craves ever bigger thrills and ever bigger tensions; he is not satisfied by money, power, or even sex... only war. Big Boss then states that as a warrior Snake realizes all of this already and has the same killer instincts, something Snake tries to deny.
What Big Boss tells Solid Snake about his true nature later becomes a big part of his Character Development in the first Metal Gear Solid and is later reinforced by Liquid telling him the same thing, he comes to the conclusion that they are right. Snake tries coming to terms with the fact that being a mercenary meant that he was a Blood Knight, and realising that he could use his Blood Knight tendencies for the forces of good.
Raiden was raised to be a Blood Knight, as he was a child soldier. He's apparently still a full-fledged Blood Knight now, going by his comment about "having some fun" shortly after his superiors at a PMC told him that he has to take out a Cyborg that ambushed them.
Quite a lot of the soldier characters in the Metal Gear series qualify, actually. Other than Big Boss, Solid Snake, and Raiden, there is also Gray Fox, Olga Gurlukovich, several of the FOXHOUND members, and possibly Solidus Snake.
The Boss claims to be a blood knight as well, but it seems her trip to space and assassination of her own lover made her want to unite the world rather than fight it. Still, whether she is acting or not, she says she wants to make her final fight with Naked Snake the "best ten minutes" of her life.
Boomerang from Wild ARMs 1 is a good example. The only thing he cares about is finding a worthy foe to fight, and is only helping the villains because he believes that'll lead him to the fight he seeks. Not even Hell itself can stop his pursuit of the ultimate battle. The same could arguably be said for his wolf companion, Lucied.
Ubel in Battalion Wars, somewhat. He serves Xylvania at least partly for the... entertainment value. Interestingly, he does support both Kaiser Vlad and Ingrid as a dim but loyal little brother figure, whose main ambition is to be "governator", rather than a kaiser himself.
Aran Ryan from the Wii version of Punch-Out!!. He even hits himself between rounds.
"Fightin's like breathin', Mac!" "Keep hittin' me. I love it."
Zer0 in Borderlands 2 fits this trope pretty damn well. His backstory reveals that he came to Pandora specifically to find more challenging kills, if his murder-happy haikus such as "A critical kill / Showers me in blood and spit / How enjoyable" didn't make that glaringly obvious.
Krieg even more so. He only seems interested in killing and carnage, though the small part of him that's still sane keeps him from harming any innocents.
Xenogears's Id is a fine example of this. He fights because being a split personality of Fei, the hero, created as a means to endure serious abuse he is incapable of connecting with others in any other way. At one point the heroes drop their Cool Ship the Yggdrasil atop his Humongous Mecha. Moments later, the Yggdrasil cracks in two, rising off the sands...
"That was interesting. But dropping a battleship on me is cheating. Take it back..."
Captain Falcon's theme song in F-Zero GX seems to be from the point of view of a Blood Knight that idolizes Captain Falcon.
Final Fantasy I: Garland, the Tin Tyrant, is given a more philosophical take of this characterisation in Dissidia: Final Fantasy; he believes that all existence is a repetition of "the cycle of battle", and that all attempts to bring peace to the world are futile. He actually gets offended when his nemesis, Warrior of Light, promises to rescue him from the Cycle. Later on its shown that the reason Garland loves fighting is because the cycle of the war of Chaos and Cosmos has gone on for so long, he's lost all hope of it ever ending and has resigned himself to an eternity of fighting. Taking delight in doing so is Garland's way of adapting to the "Groundhog Day" Loop he's stuck in.
Garland [to the Warrior of Light]: It is time for you to accept the cycle and embrace combat's grim pleasure!
Sephiroth in the same game is implied to have Blood Knight tendencies, such as, shortly after fighting the Warrior of Light to a draw, Sephiroth implies while trying to give him a Not So Different response that he himself is in the conflict because he enjoys the fight.
Shadow from Final Fantasy VI is another example of a character who likes to fight for its own sake. Or at least, "it's the only thing I know".
Pit Lords of the Burning Legion in World of Warcraft fit this trope. They are hulking demons that exist only to fight and destroy. They revel in combat and don't even particularly mind dying if they get killed in battle and take as many enemies as possible with them. Brutallus, a boss in the Sunwell Plateue has some appropriate quotes:
"Beat or be beaten! Such is the way of the Legion!" "Another day, another glorious battle!" (on death) "Now this gets interesting..."
The class introduced in Wrath of the Lich King is called "Death Knight", elite soldiers of the Scourge. Their only job is to kill for the Scourge, and to cut down anyone who stands in their path. One of your first tasks as a Death Knight is to kill one of your own kind to prove your loyalty. When you succeed by showing no mercy and no restraint, you are praised and given a BFS. You're then sicced on a village to kill everyone. Although the player class then breaks free from the Lich Kings control, they are still the most fitting class, and the Deathknight faction in Northrend is clearly filled with this.
"Harness your hate, make it useful!"
Garrosh Hellscream, much like his father. He has practically no reason to hate the Alliance and didn't even drink the demon blood that turned most of his kin into berserkers. Why Thrall gave him command of the Northrend forces rather than the more reasonable Saurfang is anyone's guess.
Varian Wrynn, or at least his Lo'gosh side, lives for battle. He could spend the rest of his life killing for sport and be happy, and probably would if he didn't care about his responsibilities.
Soldier and Heavy from Team Fortress 2. Well, everyone except the Sniper and the Spy (the "professionals").
Saxton Hale breathes this trope. He lives for a fight, whether it's against vile villains or dangerous animals. Unfortunately, this bites him in the ass in "Ring of Fired". He has a policy of giving Mann Co. to a rival CEO if they can beat him in unarmed combat. But he falters when he finds that the CEO of Gray Mann's company is a little girl, since even he couldn't bring himself to beat her up.
The krogan are a living, breathing, walking and talking example of this trope. It even carries over to krogan multiplayer characters, who can often be heard laughing in the midst of a heated battle. In the second game a crew member, Grunt, born via test tubes has a good laugh over brutal imagery from his tank and cites that there's no joke to what he's seen only that, "It was a good fight."
Grunt makes this even more clear if he's the one who radios you during the final boss sequence. Every other party member will say they're being overrun when ordered to fall back, whereas Grunt...
Grunt: Shepard! You're missing it! It's goddamn glorious! I'll climb out on their bodies!
Wrex is a much wiser and more reasonable krogan who recognizes that there are things more important than fighting... but whenever he does fight, it's obvious that he's having the time of his life. In the Citadel DLC, he even reveals that he's always wanted to have a fight through the Normandy's CIC, for no reason other than that he's Wrex.
In the sequel, Garrus has shades of this, though he keeps up certain standards:
Garrus: Gardens, electronics shops. Antique stores, but only if they're classy.
Despite his above snarky approach to it, during gameplay if you have Garrus in your party during a firefight, he will loudly announce his kills with childlike glee.
The third game has Kai Leng, a Canon Immigrant from the novels. His back-story is that he enlisted in the military at age 16 using false credentials, and made it as far as N7 - the same program that produced Shepard and Anderson - before showing his true colors in a bar fight. He was discharged and thrown in jail, only to be broken out by the Illusive Man, who put him to work as an assassin.
Shepard: (while your squad point their guns at Leng) Three against one. Now it's over. Kai Leng: No. Now it's fun.
A Renegade Shepard definitely comes across as one. Unlike Paragon Shepard, they don't go around the Galaxy because there is always someone who needs saving but because there is always someone who needs their head smacking together or taught a lesson. And these lessons often involve bullets.
Sir Raimund Seyfarth from RosenkreuzStilette counts as this, having given up on relating to nearly everyone as he had become an embodiment of Death who craves only battle. Also, Schirach Fuehler from the sequel ~Freudenstachel~.
Akihiko Sanada from Persona 3; as early dialogue and his glimpse into the past from The Answer tells, he was all too eager to join Mitsuru in taking out Shadows, all for the sake of strength. His goal has no real aim; it's all a coping method to get over his little sister's death that he claims he's responsible for (she died in a house fire, a situation that was largely out of his control), and with the result being that he has the social skills of a brick, no other friends aside from fellow orphan Shinjiro Aragaki (who has his own closet of issues), has no other real knowledge other than trivia about exercise and training, and is completely hopeless in romantic situations. He spends the first two months of the game complaining about not fighting due to an injury, and even after Shinjiro is killed and he finds his resolve to fight for the sake of protecting others, his desire for battle doesn't fully go away (when deliberating to fight the Final Boss, knowing how hopeless it is, he jumps in without a second thought), and his social density doesn't improve at all. Even three years later when Persona 4 Arena rolls around, we find him on a global quest to fight the best of the best, for the sake of power, that he dropped out of college to do - in other words, the exact thing that he resolved to give up in the first place.
The Mithra in Final Fantasy XI have shades of this. We have not yet seen their homeland, but the Mithra we do see are predominantly mercenaries who are spoiling for a good brawl or just lazing about and enjoying good weather... similar to normal cat behavior in a way. So yes, Mithra are more on the mellow end of the Blood Knight scale, content to enjoy life, but if the chance for a fight picks up, the bravado quickly kicks in. This is all especially visible in the Wings of the Goddess expansion when you see the Mithran role in the Great War.
Fawkes is like this, but only in combat. After blowing away an enemy with his GatlingLaser, he'll laugh and shout, "Too fun!" But outside of combat he's surprisingly gentle and polite; also, he will only be your follower if you have high Positive Karma.
Legate Lanius of Fallout: New Vegas. He openly mocks Caesar's Frumentarii (the intelligence and assassination division of their forces) as cowardly and underhanded, preferring direct and spectacular action, and is correspondingly viewed with wariness by both Caesar and Vulpes (the head of said Frumentarii). In all but one of the games endings, he serves as the Final Boss. And he is tough. He also claims that his ideals will "free people in ways they can't see". His proof? You.
Ellis in the sequel is a more naive version of this trope, but he still views the zombie outbreak as a way to have some fun, especially going to an abandoned carnival.
Bill grows out of his Blood Knight tendencies as he spends more time with the other survivors; he sees Louis as a very helpful guy to have around (the comic reveals that he created the pipe bombs), Francis as a tolerable son of a bitch that can kick some ass, and Zoey as a granddaughter. He vows to protect the fellow survivors at all costs and stays true to his word in The Sacrifice campaign where he sacrifices his life to restart the generator to raise the bridge so the other survivors can escape the horde of zombies and then get away to some remote islands.
Sgt. Avitus from Dawn of War 2. "He wields his wrath as his most powerful weapon". Granted, the 100-caliber heavy machine gun probably helps. How khornish of him. Canonically, his bloodlust caused him to become corrupted and fall to Chaos, betraying Commander Vanilla Ice.
According to Master Xehanort's reports in Kingdom Hearts: Birth by Sleep, this is one reason that the Keyblade War got so bad. Every Blood Knight in the universe flocked to it and started fighting both sides indiscriminately.
Starcraft: When his home planet is overrun by aliens, Fenix is actually excited to be fighting a stronger enemy than ever before. Even after he's killed and brought Back from the Dead, he doesn't mind being part machine, as long as he can still fight. This may be a common trait with Protoss. The Zealots seem to be using melee weapons only because it's more 'honourable' and gives them a better battle, for instance. Some Protoss in the second game say that they are looking forward to doing battle with Raynor's forces, and when defeated the leaders wish him luck as they retreat.
Jack Krauser was revealed to be one in Darkside Chronicles, which also acted as one of the reasons for his Face-Heel Turn in Resident Evil 4 (Let's just say that the last mission that he had, which was with Leon, resulted in him being kicked out of SOCOM due to an arm injury he suffered against one of the monsters that never quite recovered, something that he evidently didn't take well as he felt the battlefield was his life and could not function in regular society.)
The Aztecs in Civilization V is a whole faction of these. That is at least how they will be played due to their faction ability, which grants the civilization a bit of culture for every kill. Combined with the fact that their iconic unit heals after killing, means they will always want war.
This has long been the Hat of the Aztecs, who have been "militaristic" since Civilization III. It's particularly pronounced in IV, in which the Aztecs are probably the single most annoying neighbors to have, as they will attack given the slightest opportunity, regardless of the chances of victory. This is also true of the Zulus.
The Persians in Civilization V are just as bloodthirsty as the Aztecs. If you find yourself starting on the same continent as them and a few other starting nations, the Persians are almost always guaranteed to rampage through and conquer the entire continent. You can hold them off from harassing you by using gifts and diplomacy and they'll see you as a cute little harmless nation until they run out of other empires to take over and they'll swiftly turn their eyes and swords on you. It's often best to wipe them out as soon as you find them.
The Huns in Civilization V: Gods and Kings are more likely to become this since their unique ability "Scourge of God" is highly relevant to world conquest.
Nathan Drake from the Uncharted games. In practice he's an Action Survivor, but one of the Big Bads thinks that Nate must be some kind of Blood Knight in order to keep throwing himself into dangerous situations.
Marlowe: I wonder what you're really afraid of. Not bullets or blood or broken bones. No, you get off on all this, don't you? Cheating death...
Shale is a definite Blood Knight. When her true past is revealed as a dwarven woman, she suggests that she would like to do something "girlish" like smashing something soft and squishy and then watch it fountain blood.
Oghren is a Deconstruction. He fell out of favour in Orzammar after his berserker training caused him to accidentally kill a man in a friendly Proving, but his victories in the Deep Roads made him too popular to execute or exile. The Assembly decided to strip him of his weapons and forbid him to carry them in city limits, making him a warrior banned from fighting. Coupled with his wife leaving him along with the rest of their noble house, he sought solace in the bottom of a glass and has remained their ever since. Part of the reason he joins the Warden's party is the excuse to be able to fight and feel useful once again.
In Awakening, Oghren is revealed to have abandoned his new wife and child to join the Grey Wardens, knowing that his warrior tendencies couldn't let him settle down into civilian life and that his life was a mess between all the drinking and fighting. The Warden can convince him to make amends with his wife and keep in touch with his child, making them proud of him serving with the Wardens.
Kobra of Mortal Kombat reflects the dark side of this trope. He was once a promising martial artist, but was frustrated by the fact that he wasn't allowed to do his moves at their full force in his karate classes. He began prowling the streets of New York looking for a fight. He starts off fighting gangbangers and drug dealers, but with time he develops an insatiable bloodlust, which leads him to endless violence, bloodshed, and theft until he is finally arrested. This bloodlust is exactly why he gets recruited to the Black Dragon clan.
Considering how the heroes in Dungeons gain Spiritual Energy by fighting and getting hurt in battle, they're probably this.
Augus from Asura's Wrathis this trope. The man lives, breathes, and talks for the fight. Rarely a word comes out of his mouth that isn't about fighting. He sums it up best with this quote, during his battle with Asura.
Augus: "I don't fight for good, and I don't fight for evil! I just fight!"
The Barbarian class is this as well; amusingly enough even they are uncomfortable with the Templar's zeal as shown in Act 4.
Dwarves in Dwarf Fortress periodically receive a happy thought: "He/she took joy in slaughter lately." When people will use their own children as improvised weapons, you know you've got a Blood Knight on your hands.
Granberia in Mon Musu Quest 2. She wants to fight the main character not because she opposes his ideal of humans and monsters living together, but because he's simply one of the few beings that she can fight on equal terms with out of enjoyment, as she does not (usually) fight opponents to the death and thus has to hold back most of her strength while fighting.
Giacomo from Baten Kaitos, as well as his flunkeys Ayme and Folon, exhibit definite shades of this. Giacomo LOVES fighting and is obsessed with being the strongest, to the point that he once he marks Sagi as his Worthy Opponent in the prequel, he spends the rest of his appearances in the game stalking and challenging him. As for Ayme and Folon... they're pretty much just professional sadists who enjoy picking on the weak just as much as they enjoy fighting a challenging foe.
Chains in PAYDAY: The Heist is portrayed as one, living on the rush of adrenaline. It's implied the whole group becomes blood knights after the initial bank heist, as one of them says they have enough money to live comfortably for the rest of their lives, but they want to do other heists.
The latest edition of BlazBlue introduces Azrael, fist fighter from Sector Seven, who (at least according to Jin) has gone as far as attacking his own allies and committing GENOCIDE to slake his thirst for battle. Additionally, the Tattoo that covers his body acts as a power limiter, which he put on himself so we wouldn't kill his enemies outright. That way, he wouldn't get bored with them.
Tommy Vercetti from Grand Theft Auto: Vice City. Unlike other protagonists of the series, seems that his hobby is killing, either for money or revenge, without remorse, without mercy and without excuses.
WildStar has the Draken, who, while actually very intelligent and could, in fact, have a sizable role in Dominion politics, choose not to, simply because murdering things is so much more fun.
The Second Circle of Elder Gods in Lusternia is a whole pantheon of these. Shikari is regarded as a Blood Knight even by their standards, though, prolonging fights and playing with his prey for the pleasure of it.
Implied at the end of Carn Evil. The player character Jacob enjoyed shooting his way through the Circus of Fear so much that he places the magic token into its slot again over Lisa's protests.
Most likely "Freedom Knight" Alion Lucada in Super Robot Wars Compact 3...though to be honest, being a Blood Knight is a requirement for any Shura warrior. According to Folka, the Shura don't just fight for the sake of it, but they fight to win, which makes it very important that they gather THEIR forces up first.
Monk Barras Lehr from Bravely Default most definitely qualifies. Nearly every line of dialogue from him either talks about his love of fighting, how good he is at fighting and how upset he is when he doesn't get to fight. In fact, when you beat him in battle, he's not so much angry about losing as he is disappointed that he can't fight you anymore.
Per the page quote, DarkPitreally enjoys fighting and will take every opportunity to try and pummel you. At least until the last few chapters of the game where he joins forces with Pit to help save Palutena, and then to fight Hades — given he's an enemy to all living things.
Silver, from Pokémon Gold and Silver and its remakes. It's partially to prove his superiority over others (he loses the need for that as part of his Character Development) and partially because he apparently just likes fighting.
Lancer in Fate/stay night 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 Eien no Aselia. The former is rather honorable and the latter is something of a worthy opponent. Both of them serve as The Dragon to other villains. Uruka later makes a heel face turn and admits that while she really likes fighting, she hates killing.
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 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.
Reader: Excited when we lose, grumpy when we win. That's Quick Man.
Allegro, the eponymous Greatest Killer, also falls into this.
In Schlock Mercenary, most of the mercenaries are Private Military Contractors 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.
Vesa Turunen of Survival of the Fittest version two shows signs of this in his death scene, even believing that his death at the hands of 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 Social DarwinistJerk Jock, 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 Word of God) 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 Whateley Universe 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.
SCP Foundation: 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. 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 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 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 Twitch Plays Pokémon Crystal has occasionally been written like this, as has his direct successor 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.
Dinobot, from the Beast Wars, 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 Sociopathic Hero 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 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 The Movie, 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.
In Ben 10: Ultimate Alien, 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 Mega Man, Proto Man seems to only be happy when he's fighting—sometimes, only when it's with Mega Man.
Binky Barnes from 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 King of the Hill 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 The Powerpuff Girls 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.
Brock Samson from The Venture Bros. 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.
Toph Beifong from Avatar: The Last Airbender is a short, 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 Earthbender, and that she's really good at both.
Korra from The Legend of Korra loves to fight and picks battles just for fun. She sees bending as purely a physical skill and ignores the spiritual side of being the Avatar.
On a more sinister note, there's the Book 3 waterbendervillainessMing-Hua and her recurring habits of threatening everyone and grinning evilly in battle.
Manny Rivera mother Maria in her alter ego Plata Peligrosa from El Tigre, she is reluctant to use the glove that gives her powers because it makes her very blood thirsty, at first El Tigre enjoys fighting crime with her but once they run out of criminals to fight she releases them from prison so she can fight them again.
In the short-lived animated version of The Tick, The Tick once notably said, "I don't want to stop evil. I just want to fight it!"
Yang from Yin Yang Yo 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.
When American lobsters meet for reasons other than mating, they determine who is stronger. If one is clearly stronger, the weaker will be permitted to flee. Otherwise, they go through a ritual of conflict that starts with whipping their antenna at each other, and ends with going for the kill with the claws. At any time, a lobster is allowed to retreat. The loser will recognize the winner for a week (assuming he survived), and flee. Female lobsters with eggs don't worry about the rituals, and just go for the kill. There's a reason lobster claws are clamped with tight rubber bands when they're being sold.
Pike are noted for their pugnaciousness and aggressiveness. They will attack anything at sight and eat them, including other pike.
Certain species of cichlid as well. Jewel Cichlids will eagerly attempt to kill anything that moves, including larger fish, human fingers, their mating partners, and their own young.
Betta Fish are well known for this behavior. They'll even attack mirrors that are put in front of them, thinking it's another fish.
King Richard I Lionheart of England.
Spartans in their heyday had a culture built around finding honor and glory in battle. Spartans had the luxury of spending almost all of their time training for war because their culture was built on slave labor. To protect this lifestyle, their focus had to be on keeping their slaves under control rather than going off on campaigns of conquest. Spartans were also not quite as suicidal as sometimes believed. They did occasionally flee battle, but this mostly happened during the dwindling period of their warrior culture.
The Theban Sacred Band fit into this role. They were 300 of the absolute best soldiers ever, trained for nothing but war, and were essentially the Spartiates of their day, solidifying their reputation further after defeating the Spartiates head on at the Battle of Leuctra. Their most distinctive feature: they were all homosexual. 150 homosexual couples. It was believed that a man would fight better if he were fighting alongside his lover— he would have the added incentive to fight of protecting his beloved, and nobody would want to shame himself in front of his beloved by fleeing in cowardice while he was present. The Theban Sacred Band were finally defeated by Alexander the Great at the Battle of Chaeronea, where, after the entire Theban army and their allies fled the battlefield, the remnants of the Sacred Band fought to the last man, some even committing suicide rather than be taken prisoner. Philip II, Alexander's father, when seeing the corpses, reportedly said "Perish any man who suspects that these men either did or suffered anything unseemly."
Many Australians who enlisted to fight in World War One and Two—especially two—signed up with this motivation; this fellow◊ mentioned in the Australian official history, for example. This was largely because the AIF (Australian Imperial Force) was composed of strictly chosen volunteers (the Australian Commonwealth Government didn't have the constitutional authority to send conscripts abroad).
Charles Hazlitt Upham. VC. And bar. Read the War Office citations for both. In the history of the Victoria Cross exactly three people have gained a bar to their VC. Upham was the only combat soldier. Charles was later captured and sent to Colditz Castle for no less than four previous escape attemptsnote After the third he was kept in solitary confinement and only allowed out for exercise in a small courtyard, with two armed guards and a machine-gunner watching his every move. He made a run for it anyway in a act so audacious the gunner held fire out of sheer respect. When the camp was liberated, he broke into the prison armoury and went hunting Germans. The repatriation committee had to track him down and order him onto the plane back to England, as he'd tagged along with the Americans to get back into the action quicker.
World War II general George Smith Patton. He expressed a bizarre fascination with warfare from a young age, which contributed heavily to his famous hard-nosed personality. He gleefully volunteered for any combat assignment offered to him and loved warfare, despite being badly wounded as a tank commander in WWI. In between the World Wars, he and his friend Dwight D. Eisenhower spent their free time driving around in a civilian car with guns hoping bandits would try and rob them. Although he believed that he had been reincarnated repeatedly so he could fight and die again, his odd worldview made him one of the Allies' best generals. He once said, "An entire world at war and I'm left out of it?! God will not permit this to happen! I'm going to be allowed to fulfill my destiny!" Fittingly, he died in a car accident four months after the end of WW2, as a world at peace was no world for him. After VE day and before his fateful car crash, Patton was fully prepared and eager to fight the Red Army and its allies next - he dismissed the skills and experience of commanders like Zhukov and Rokossovsky, and dismissed their troops' greater experience and numbers (they had more than thrice the Allies' combat troops and twice their AFVs) on the grounds that they were all Slavic Communists who could never beat a Freedom-Loving Anglo-Germanic foe.
Patton's confidence was not merely ethno-centric, the Red Army had no real supply chain compared to the Allies. The Red Army quite literally lived off the land (harvesting crops, farm animals etc) to feed their troops during the invasion. While this worked for their invasion of the Third Reich, they had already consumed the resources and thus would have had nothing to sustain themselves had Patton attacked and forced them into a defensive action. (Huge numbers can boomerang from a great advantage to a great liability if you can't feed them.) The allies meanwhile had mastered the supply lines necessary to bring resources from overseas. Patton actually would have had fair odds of pushing the Soviets out of Europe proper, though whether he could do a better job of taking Moscow than everyone else who has tried is another question.
Though likely not for Patton himself, as he famously said "My flanks are something for the enemy to worry about, not me. Before he finds out where my flanks are, I'll be cutting the bastard's throat." In the event that Patton was granted his wish, it seems unlikely he'd have considered the ramifications of fighting the Red Army in its own territory (besides looking forward to it), and almost certain he wouldn't have willingly stopped at Moscow (since the Soviet government had already fully prepared to abandon the city to another invasion from the west.)
If you believe the accounts, the "factions" of Ireland that were common in the latter half of the nineteenth century were a pleasurable variation on this trope. The closest fictional example to the attitude behind it would be the frequent Fight Clubbing between the Gauls from Astérix's village. The reasons were frequently trivial or nonexistent; they fought for the fun of it and if someone died, well, as long as it was a fair fight, it wasn't meant in malice. Sticks and stones were the Weapon of Choice, women and children could "join in" and the larger brawls were prearranged for meetings such as fairs. From the article:
A challenge to fight was often less a reflection of animosity than an invitation to engage in a convivial form of recreation.
If the accounts of samurai are to be believed from Kamakura and Muromachi-era Japan, many samurai could have been considered Blood Knights. It was custom at the start of battle for samurai to advance toward the enemy without any larger battle plan, shout their names and seek a worthy opponent, then decapitate them and move on to the next. All samurai were paid according to their head count. (This encouraged samurai to poach kills off already-dead foes killed by non-samurai, which itself led to the interesting practice of head-viewings.)
Historians believe that one of the reasons (among a few others) why Toyotomi Hideyoshi led the recently united Japan to war and invasion against Korea in the 16th century was to keep the samurai from killing him and each other. Considering that this age of unification and peace was relatively brief, his worry was probably not misplaced.
Khalid ibn al-Walid, one of the best military commanders period (as he is among the few historical generals who never lost a battle). According to A.I. Akram, one of the motivations for his conversion to Islam is because the Muslims of that time were busy conducting military campaigns across Arabia and he felt that he was missing out on the glory. Somewhat of a Death Seeker too, considering that he spent his last days lamenting that he will die of old age instead of battle. No wonder his sobriquet was "the Drawn Sword of God".
While this may be apocryphal, there is a story that Frederick the Great turned into this during battle, deliberately cutting himself and working himself into a frenzy.
Theodore Roosevelt had elements of this at times. He demoted himself so he could fight in the front lines during the Spanish American War. He also referred to his one genuine experience in battle, San Juan Hill, as "the greatest day of my life", and, when he was dying, expressed regret that he didn't die in battle. During his political career, he spent most of his pre-presidential career clamoring for a war to fight in, and explained once that he didn't start any wars as president because the idea of being cooped up in the White House rather than on the front lines during a war was unthinkable. He spent most of World War I begging Woodrow Wilson for permission to form a volunteer regiment and get sent over to Europe.
Walter Cowan, Royal Navy. Commanded a battleship at Jutland, and loved war so much he spent his leave periods in the trenches on the Western Front. When the Armistice was signed, he cried. Retired as a Rear Admiral. In WW2, despite being well over age (he was in his seventies), he joined the British Army in Africa and fought against the Italians. Captured when trying to SINGLE-HANDEDLY ASSAULT A TANK WITH HIS REVOLVER, he was repatriated by his enemies as an act of mercy (because of his age) and immediately tried to join the Commandos.
Bernard Freyberg VC, given the habits that caused Winston Churchill to call him "the Salamander" (always in the fire).
John Basilone won the Medal of Honor at Guadalcanal in 1942, manning a machine gun (alone) to hold off Japanese troops. When that stopped working, he used his pistol. After he was sent home, he was uncomfortable with civilian life and re-enlisted to fight at Iwo Jima, where he took over a blockhouse full of Japanese soldiers single-handedly and fought until he was killed by mortar shrapnel.
Winston Churchill himself was a particularly crazy Blood Knight. He and the British chiefs of staff formed Operation Unthinkable on May 22nd 1945, which would have started a preemptive war by the United States and Great Britain against the Soviet Union. The fact that the Soviets outnumbered the allies by more than two to onenote was the least of their problems. What the planners didn't even realise they should take account of was the Soviets vast experience and skill at large-scale warfare (something the Allies had no experience with). One has big problems when one tries to fight a big war using the same methods one uses for small wars, as the Germans had discovered, not least of which being an inability (on an institutional/overall level) to focus on the 'bigger picture' because of an obsession with micromanagement. The Allies spent three years campaigning to take Italy and France with less than a million men (and half a million replacements) from another million men (and half a million replacements). In the same period the Soviets used more than four million men (and three million replacements) to take an area bigger than India from three million men (and two million replacements) was the main reason why the plan never taken seriously.
Adolf Hitler was probably the most famous Blood Knight of the modern age. He wanted to go to war even in 1938 to take the Sudetenland. There was testimony from surviving Nazis that Hitler loved the idea of enormous battles with enormous casualties even when it made no sense to lose so many German troops needlessly.
Andrew Jackson suffered from having a bullet in his lung and is said to have dueled at least 100 times and loved scalping Indians. Although this might just be because he's nuts. There was an assassin who tried to kill Jackson while he was in office. On a misty day, the man drew two pistols and tried firing them at Jackson. Both guns jammed. Jackson, meanwhile, was busy rushing the gunman from over 100 feet away and beating him into unconsciousness with his cane. Jackson was asked why he rushed the man when he was facing two guns. He replied "I would rather have a closed casket (funeral) than get shot in the back, fleeing like a coward."
Jack Churchill was an allied commander during WWII and volunteered for commando duty. He carried a claymore into every battle and is credited with capturing 42 Germans and a mortar squad using only his sword. He was finally captured by Germans after the rest of his squad was killed by a mortar shell. The Germans cautiously approached him as he played "Will ye no come back again?" on his bagpipes, which he also carried into every battle. He was sent to a concentration camp, which he promptly escaped. He was soon recaptured and sent to another concentration camp, which he also escaped. He finally made it back to Britain to find that the war had ended. He was quoted as saying, "If it wasn't for those damn Yanks, we could have kept the war going another 10 years!" He is also the only man to have got a kill with a longbow in World War II.
Ronald Speirs of Band of Brothers fame. He would turn up wherever there was fighting whether his unit was engaged or not, chose to stay with his company after European hostilities ended in the hopes of getting transferred to the invasion of Japan, then stayed with the army to serve in the Korean and Vietnam wars.
Child Soldiers are raised to show no mercy and are only praised and given food when they kill. They will ruthlessly murder innocent civilians, or kill mothers and kidnap the children so they will be raised as child soldiers. Many of these children have a hard time fitting in with normal society, as their empathy has been suppressed for so long.
Charles Askins is an odd example because many of his killings were as a non-military border patrolman. During his long career as a policeman and soldier, Askins took deep pleasure in the fact that he had killed 27 people, "not counting black people or hispanics." Among other things, during an ambush he once ordered soldiers under his command not to fire until he fired first, because he had a pre-distribution .44 Magnum and he wanted to be the very first person to get a kill with it.
According to some historical documents, at least one of the reasons why Benedict Arnold ended up defecting to the British is because of anger that he was not allowed to serve actively in the Revolution because of an injury he sustained when attempting to recruit Canada to their side that ended badly, as he viewed service to the military as being his life. He was re-injured at the Battle of Saratoga, and then sidelined. Washington set him as military governor of Philadelphia, which the Colonists had just recovered and which was a hotbed of Tories - and beautiful Tory women...
Bobby Fischer was sort of a chess version of this — leaning way over into Sociopathic Hero territory. It was said he liked humiliating players as well as beating them. According to one legend, he visited a harlot, and when he left, said that Chess was more fun.
Ernst JÃ¼nger - German novelist/author and WW1 SturmtruppenfÃ¼hrer. Yep, the people handpicked to storm the enemy trenches all by themselves. And he wrote a book about that, "In Stahlgewittern". Which proves that he was truly 'psychopathically brave'.
Most gamers, as 90% of games are about killing the enemy. Because video games are completely virtual and there are no permanent consequences, they can enjoy fighting without their Blood Knight attitude necessarily translating to real life violence. This is why games like Call of Duty and such are so popular, but this large gaming demographic has been criticized for enjoying games that are said to be "vapid and simplistic" compared to the more "intuitive" ideas. Of course this isn't to say that all violent videogames are "vapid or simplistic", for some gamers it's more about killing the enemy in an awesome or over the top way rather than just simply killing.
A long time ago, the Spanish were sailing in the Caribbean when they found a group of three islands full of very aggressive Indians. Remembering the Spartans, they named these islands "Nueva Esparta" (New Sparta). One of their greatest moments was during the Independence war: thousands of royalists against hundreds of Neo Spartans, their weapons couldn't match the enemy's... and they won. Ever since then, both the battle and the mountain where it happened is called "Matasiete" ("Seven at one blow"), even though the real proportion was ten to one.
A bit of a deconstruction; European Knights, from about the 10th Century to the 16th. These men were trained, often from birth, to believe in nothing but war and God... and without any code to constrain them, they took any fights they could, so long as they were advantageous. This translated to bullying anyone weaker than them, including peasants, other nobles, merchants, even bullying rulers. Even when the Code of Chivalry constrained them (in that they were expected to no longer go killing anyone for their stuff, no actual real bonds), Knights were significant social factors in the declarations of war in major European powers like France, England, The Holy Roman Empire, Spain (primarily Pre-Reconquista), and Hungary.
The Mongols led by Genghis Khan; under his leadership he united the scattered tribes of Mongolia, and transformed them into a unified Empire that had conquered half the world. Genghis Khan always made sure that his armies had some enemies to fight against, so they didn't have to fight each other all the time. The Mongols ravaged everything in their path, they burnt down cities, massacred the inhabitants, and piled their corpses in massive heaps. In their run, they conquered China, decimated Persia, ravaged Russia, utterly erased a few empires from history, and would have overrun Europe if they could.
The Vikings. Valhalla was exclusive for warriors who fell in battle and consisted of fighting all day and feasting all night.
And then, by sheer heritage: Norwegian soldiers serving in Afghanistan. "To Valhalla!" indeed...
The Aztecs created an empire that ran, quite literally, on the blood of conquered enemies, as their religion required blood sacrifices to keep the universe working, more or less. Because of this, the Aztecs were always seeking prisoners to capture and kill and went to war frequently, even constantly. The Aztecs even went so far as to have ritualistic "Flower Wars" for the exclusive purpose of capturing prisoners to sacrifice and to train new soldiers. Hell, you even needed to kill people just to get ahead in society and promoted at work!
