Screaming Warrior



""Are those HIYAHS really necessary?""

- Lord Zedd, Mighty Morphin Power Rangers

The polar opposite of a Screaming Woman. While a Screaming Woman instinctively yells at the top of her lungs at the first sign of terrifying danger, hikes up her skirts, and runs away from it, screaming all the way, a Screaming Warrior yells at the top of their lungs at the first sign of terrifying danger, hikes up their weapon, and then proceeds to charge headfirst into it, screaming all the way. Occasionally, the Screaming Warrior is the terrifying danger, at least to his enemies. Or friends.

Everyone likes a good Battle Cry right before a big fight, but this character just keeps on yelling even while the fight is well underway. Perhaps it's to intimidate their opponent, maybe it's just a habit, maybe it's to follow tradition, or maybe it's just cool to do. For bonus points, once the fight is over, don't be surprised if the character lets out one last cry of victory while standing over the pile of heap that was their opponent.

Not to be confused with Make Me Wanna Shout (where the screaming is an attack in its own right).

Make note that the trope is not limited to simply to screams. Loud, consecutive grunts and various roars very well qualify. A Screaming Warrior is most likely an angsty Badass, Action Girl, Proud Warrior Race Guy, Hot-Blooded, a berserker or all of the above.

Compare Calling Your Attacks, Kiai, Leeroy Jenkins, Stab the Sky, Shouting Shooter.

Anime & Manga
"Gemu giru gan go gufo... VIIIIIIIIIITAS!"
 * Subverted in an episode of Full Metal Panic Fumoffu, the main character attempts to train a group of hot-headed Yakuza members not to be Screaming Warriors when they attack someone.
 * Subverted in Utawarerumono: Oboro starts out as this kind of character... But is later shown going out of his way to not scream during battle, after realizing how ridiculous and inefficient it is.
 * The entirety of the Dai-Gurren Brigade from Tengen Toppa Gurren Lagann is just so goddamn Hot-Blooded, they always give the most badass screams ever while fighting. WHO THE HELL DO YOU THINK THEY ARE?!
 * The main protagonist of Gao Gai Gar, Gai Shishio, may very well be the king of this trope. He screams before and after just about everything he does. This is most apparent during the finale of the TV series, in which Gai is so enraged by his foe after it blocks his most powerful move, he completely forgets to do anything -but- scream. And totally brutalize the monster.
 * Guy powers up his Finishing Move in FINAL by adding screaming to it. Really.


 * Father Alexander Anderson in Hellsing Ultimate alternates between AAAAAMEN, and pure incoherent rage when fighting vampires.
 * Lampshaded and somewhat subverted in the Vagabond manga. In an early volume, Yoshioka Seijuurou explains that beasts and men both scream loudly when they themselves are afraid of a fight and hope to intimidate their enemy and escape. Later we see this play out with Miyamoto Musashi himself, when he first fights Inshun and is being completely outclassed, he lets out a wild scream as he's attempting to fight down his own panic and goes into a berserker attack in a last ditch effort. When that fails and he realizes that Inshun is about to kill him, he flees in terror before passing out from his wounds.
 * Musashi however would end up on the other end of this trope when he took on Seijuurou's brother Denshichirou the second time; it was Denshichirou who would do this, having an effect on everyone in attendance but Musashi, after Musashi asked Denshichirou to simply stop the duel. (If anything, Musashi is left wondering why Denshichirou was screaming when it'd just stiffen the muscles he'd use to swing his sword.)
 * Also subverted by Denshichirou years before against the surprisingly powerful and even intimidating Sasaki Kojirou, by declaring his lineage... only for Kojirou's companion to point out that 1) Kojirou probably didn't know of Denshichirou's father and 2) Kojirou's deaf.
 * "TEZUKAAAAAAAAAAAA!!" in The Prince of Tennis (appropriate when one is the slightly megalomaniacal tennis captain of a rival team facing off against Tezuka Kunimitsu).
 * Every fighter in the Dragon Ball series, but especially Broly. Imagine the shock of some fans of the dub when they found out his voice actor was Vic Mignogna...
 * Ow, my poor vocal chords.
 * Ayato Kamina from Rah Xephon fought like this constantly. He had a pretty bad habit of screaming his lungs off as he charged. Of course, the RahXephon is a mech enhanced by song and sound, so maybe that explains why it kicks so much ass.
 * At one point parodied, when he attempts to activate a special move in the laboratory... by screaming louder and louder.
 * Askeladd in Vinland Saga tries to tell Thorfinn, the protagonist, not to be one of these, explaining that a warrior that loses his cool often loses his head. Thorfinn, being Thorfinn, doesn't listen, so Askeladd is forced to teach him the truth of the matter rather bluntly.
 * In Katekyo Hitman Reborn, most notably Ryouhei and Squalo are this. With Ryouhei yelling out "TO THE EXTREME!!" and Squalo's Battle Cry being "VOOOIIIIII!!"
 * Vita and Subaru of Magical Girl Lyrical Nanoha. What'd you expect from two Action Girls with Gao Gai Gar nods?
 * Despite bordering on The Quiet One outside of the battlefield, Vision of Escaflowne's Van Fanel quickly picks up the habit of screaming bloody murder during anything resembling a serious fight.
 * When Guts of Berserk gets really pissed, he'll often let loose with a scream of pure rage as he starts laying about with his BFS.
 * Digimon Frontier, taken to ridiculous levels in a show that had not made a habit of it before.
 * Shinn Asuka from Gundam Seed Destiny and his wrathful howls that make him sound like the most psychotic Blood Knight...except he fights because he wants peace. Badly. And he hates ORB. And boy, he will never let someone forget the ORB part.
 * The end of chapter 46 of Neon Genesis Evangelion gives us a 100m tall mecha with half of its chest torn off and covered in the blood of a 100m tall monster, which it just killed with its bare hands. And screaming of course.
 * Asuka, especially in her fight against the Mass-Production Evas in End of Evangelion, where nearly every sound out of her mouth is a wordless battle cry. Especially her last attempt at a kill where she starts squeezing the target's core with a demented growling; camera cuts away for a while then back where the growl amplified into a full-volume top-of-the-lung scream she continues until she sees the fake Lance flying towards her.
 * Mari from Rebuild of Evangelion simply loves this trope.
 * Shinji gets these kinds of moments occassionally, particularly his fight against Shamshel.
 * Basically every fighter in Fist of the North Star. Especially the main character Kenshiro, when using his "Atatatatatatatatatatatatatatatatata" while doing Rapid-Fire Fisticuffs.
 * In Ai Yori Aoshi, when the group is investigating "ghosts" in the darkened Big Fancy House, Aoi and Miyabi encounter what looks like a Bedsheet Ghost (actually Mayu trapped in a giant paper seal). Miyabi lets out a battle cry and charges with a staff she got from...somewhere. She winds up chasing Mayu through the halls until she's close enough to see who it is. Crowning Moment of Funny.
 * Escaflowne's Van and Dilandau usually scream a lot when charging an enemy. A dead give-away of their intentions in both cases.
 * Tekkaman Blade and Toshiyuki Morikawa showing off his microphone-breaking skills. Even then, no Tekkaman can resist shouting VOLTEKKA!
 * I HAVE SURPASSED GOD!!!
 * MUDAMUDAMUDAMUDAMUDAMUDAMUDA!
 * WRYYYYYYYYYYY!
 * Aside of Calling Your Attacks and Battle Cry, the people screamed. A freaking lot. I mean, they sometimes scream just by losing some hand or legs. Ahem.
 * Haruko from FLCL. Both just screaming and bizarre onomatopaeias for God knows what. Of course, she fights with a pull-start, multi-purpose giant club/grenade launcher/ref board/robot tool/bass guitar, so NOT screaming would just spoil the awesome.
 * CHAAAANCE!
 * What, no mention of One Piece? In battle, Luffy hollers so loudly, so often and so long that sometimes he actually has to pause to take a breath in between.
 * And let's not forget his good buddy Zoro, who somehow manages to emit warlike cries while holding a sword between his teeth.
 * Slam Dunk: Ironically, it's The Stoic Akagi who does it the most in Slam Dunk, thus living up to his nickname "The Gorilla". Sakuragi does it as well, usually to imitate his captain.

Comicbooks

 * Of the numerous Screamers within comic books, Wolverine is the most well known. The characteristic has since been endowed into just about all of his incarnations.
 * Naturally, his clone X-23 also shares the habit.
 * The Incredible Hulk ties him with the trope.
 * The Tick's battle-cry of "Spoon!" looks like it fits here.

Film

 * Rambo loves this. Especially in III, where both he and the Big Bad are Screaming Warriors while playing chicken using a tank and a helicopter.
 * For comedic effect, Han Solo can be seen in Star Wars as the Screaming Warrior chasing after a detachment of Stormtroopers, blaster drawn, until they notice he's only one he runs into their reinforcements, at which point he begins screaming and running away from them.
 * One of Bruce Lee's iconic traits.
 * Joker has 2-4 guys like this in the '89 Batman film. One of them fights Batman in an alley with dual swords, and the other three fight in succession in the belfry scene at the end. The last guy, a Scary Black Man, provides the only real threat.
 * Appears in Sinbad: Legend of the Seven Seas: after being swallowed and spat out by a sea monster, one of Proteus's soldiers charges screaming at the monster, prompting Sinbad to remark to Proteus, "Give that guy a raise."
 * Just about every male character in the film Big Trouble in Little China is one of these.
 * Kikuchiyo (Toshiro Mifune), the farmer's son crazy pseudo-samurai in Shichinin no Samurai.
 * Even characters who aren't normally warriors can pick up this habit. As Jay and Silent Bob leap in to save Bethany from the Stygian Triplets in Dogma, Jay howls "SNOOTCH TO THE MOTHERFUCKIN' NOOOOOOOOTCH!"
 * Darkwolf from Fire and Ice
 * Shan-Yu from Disney's Mulan, is the Screaming Warrior after his army is killed by the avalanche created by Fa Mulan (disguised as Ping).
 * In Star Trek III the Search For Spock Admiral Kirk is seen as the Screaming Warrior while jumping on Commander Kruge.
 * Captain Kirk does the same thing in Star Trek VI the Undiscovered Country while he saves the Federation President from being assassinated.
 * Spoofed in Toy Story, by Woody while fighting Buzz Lightyear in the gas station.
 * Brendan Fraser's character attempts to scare off a group of warrior mummies in The Mummy 1999. Turns out warrior mummies have a pretty impressive scream of their own.
 * Ardeth gets some Screaming Warrior moments too, notably in the sequel before he attacks Lock-Nah.
 * CHAAAAARRRRGE! CHARGE THE BLOCKHOUSE!
 * Last Action Hero. Jack Slater's daughter is attacked by one of the Big Bad's goons, and starts out a Screaming Woman... then continues to scream while beating the tar out of him (so his buddies will think he's still slapping her around and not interfere).
 * Allied troops yell as they charge into the dunes in The Longest Day.
 * Chinese armies usually scream SA! as they charge in movies (drawing it out, of course). It means 'Kill.'
 * Ace Ventura in the second film, while fighting the Hatutu tribe champion
 * See any Reb Brown movie, even though he Screams Like a Little Girl.
 * In The Matrix, Morpheus, when he.
 * In The Matrix Revolutions, Mifune.
 * Beaten to a gruesome death in John Carpenter's Ghosts of Mars. The leader of the zombie-type-things goes through every possible emotive inflection of "RARRrrrrh!" in his first ten minutes onscreen, depending on his apparent mood. Then he gets to deliver them all over again, a few times each. Scarily enough, this makes him one of the best actors in the film.
 * Subverted in Young Guns. When the outlaws are seemingly cornered, Chavez appears to launch his horse at a cliff with a battle cry. Inspired by his courage, the other outlaws follow and to everyone's surprise they make it unscathed. When one of the other outlaws tells Chavez that was awesome and asks what the battle cry means in his native language, Chavez gives him a wry look and says, "Stop!"

Literature
"Speaker-to-Animals: "Louis Wu, I found your challenge verbose. When challenging a Kzin, a simple scream of rage will suffice. You scream and you leap.""
 * In Larry Niven's Ringworld, a Kzin describes the proper response to a fighting-words insult as "You scream and you leap."

""...by nature dutiful, serious, literate, obedient and thoughtful people whose only minor failing is a tendency, after one drink, to rush at enemies screaming 'Arrrrrrgh!' and axing their legs off at the knee.""
 * Discworld variations:
 * Sam Vimes from the City Watch books does this in Thud!,
 * The Nac Mac Feegle do this. In abundance. At the same time. With individual yells.
 * There can be only one thousand!
 * They can take our lives, but they can never take our trousers!
 * Nae king, nae quin, nae master, nae lard! We will nae be fooled again!
 * Crivens!
 * Nac Mac Feegle wha' hae! (Pratchett admits this one doesn't logically make any sense.)
 * More specifically: Nac Mac Feegle wha' hae WHAT?
 * Waley waley waley! (although this is also a general-purpose moan/scream of discontent)
 * In Guards Guards the dwarfs are described as:
 * In Guards Guards the dwarfs are described as:

""Head teachers! Sports masters! Boys who chew gum!"
 * They also have a number of battle cries, the worst and most threatening of which is "Today is a good day for someone else to die!"
 * Carrot's use of that old classic NeeNawNeeNawNeeNaw!!!
 * Which could possibly be read as "Knee Gnaw!", given that dwarfs have been known to bite taller opponents' legs or worse in the heat of battle.
 * In Interesting Times, Cohen advises Teach (a geography teacher who joined the Silver Horde out of curiosity) to imagine the enemy is everything he hates in order to work up a good beserk:

"Smoke pipes at me, would you? You! That boy there! Answer me back, eh! Take that!""

"Miles: You know, it might be better if we don't yell, going in. It's startling. It's bound to be a lot easier to hit people if they're not jumping around and ducking behind things."
 * In Brian Jacques' Redwall series, the badgers and hares have their famous battle cry, "Eulaliaaaa!". Other characters often yell "Redwall!" or "freedom!".
 * Cnaiur urs Skiotha has a combination of this and Badass Boast. During battle, he screams challenges for his enemies to kill him or about how many of their countrymen he has killed. At one point this is intimidating enough that his enemies see him as an avatar of their god of war.
 * Sigismundo Celine in Robert Anton Wilson's Historical Illuminatus Chronicles does this in the rare instances he's forced to fight, since his fencing teacher told him it throws the enemy off. When a mild mannered intellectual suddenly screams "DIEEEE!" at the top of his lungs, it certainly seems to work.
 * Eidolon in the Horus Heresy novels.
 * Subverted in The Warrior's Apprentice after Miles observes his companion's assault on an empty room, complete with a "war whoop":


 * In Wraith Squadron, the pilot Runt has a Mind Hive. His initial pilot mind has a terrible tendency to scream a wordless, wavering warcry and plunge after the closest enemy, heedless of tactics, orders, or the fact that his craft's weapons would probably work better than ramming. His wingmate Kell helps cure him of this, and in time he apparently switches to a pilot mind that's more erudite.
 * Warcries abound in the works of J.R.R. Tolkien. Aragorn and Eomer often use the names of their swords as battle cries, and Aragorn often uses the name of his ancestor, Elendil, as a battle cry as well. The Rohirrim have quite a few warcries, and Gimli has his famous Dwarven battle cry, "Baruk Khazad! Khazad ai-menu!"

Live-Action TV
"Tom (as Dave): "Well, I got that out of my system!""
 * Xena: Warrior Princess is the crowned queen of this for female fighters.
 * Arch Enemy Callisto plays this more straight. Whereas Xena's ululation is a badass Battle Cry, Callisto just screams like a raving lunatic when she fights. But then again, she kind of is.
 * Cole Turner of Charmed
 * The MST3K episode Space Mutiny featured a hero, Dave Ryder (a.k.a. "Slab Bulkhead", et. al) who had a fondness for charging into battle while screaming like a little girl. You can see his most hilarious scream at the end of this clip which features his final confrontation with the villain. (Note how calmly the hero ditches the vehicle after screaming, thus totally ruining any drama the scene might have possessed.)


 * Tyr Anasazi of Andromeda, not usually his normal style, but when facing a group of screaming monks, returned one of his own, causing them to flee.
 * Captain Benjamin Sisko in the Star Trek Deep Space Nine 7th season episode: "The Siege of AR-558".
 * Action Girl Ziva David of NCIS lets loose with one when invited to take a shot at Jerk Jock Tony DiNozzo's abs. It quickly degenerates into cooing and belly rubbing when she halts the punch an inch from her target and takes the opportunity to mock his conditioning.
 * Chiana of Farscape has a very distinctive warcry that can best be described as "BBBBBBRRRRRRIIIIIYIYIYIYYIYAAARGH!"
 * Recurring foes the Daleks of Doctor Who customarily scream "EX-TER-MIN-ATE!" before and during attacks on any living thing they perceive.
 * In the Community episode "Modern Warfare" Jeff does this while redecorating the Dean's office with the business end of a paint ball gun.

Professional Wrestling

 * Former WWF wrestler The Ultimate Warrior built a career out of being a screaming, snarling, grunting, face-painted lunatic.
 * Those who are aware of his behavior since his retirement are convinced it's not an act.
 * SHIMMER/RingOfHonor wrestler MsChif screams at her opponent all throughout her matches.
 * Former WCW and current TNA wrestler Daffney also made her mark on the business by screaming.
 * Goldberg used to snarl and scream a lot, also. One memorable instance was at the 2004 Royal Rumble, when he was ambushed in the ring by Brock Lesnar. He snarls "You son of a bitch!" and literally hisses like a cobra. Prime Nightmare Fuel for a lot of the kids watching, no doubt.
 * Melina - though sometimes she's simply throwing a tantrum rather than trying to frighten her opponents, making her a mix of this and Screaming Woman. She does it so much, her screams are referred to as "The Primal Scream". She screams before doing both of her finishers, one of them appropriately titled the Last Call.
 * "Native American warrior" wrestlers have also traditionally fallen back on this trope (the most recent being Tatanka).
 * Kelly Kelly seems to be trying to out-do Melina in terms of screaming. It's a little unnerving to see the smiley happy Kelly suddenly turn into an aggressive Screaming Warrior whenever one of her matches gets serious.

Tabletop Games

 * Warhammer and Warhammer 40000 have the Orcish battle cry, which they are known to scream until such time as they pass out. Say it with me: WAAAAAAAAAAAGGGHHHH!!!
 * Though you can't get the full effect of the WAAAAAAAAAAAGGGHHHH!!! shout unless it's coming from at least one hundred throats. All of which are attached to berserk, bloodthirsty monstrosities that are fully capable of ripping you apart with their bare hands.
 * Also: BLOOD FOR THE BLOOD GOD! SKULLS FOR THE SKULL THRONE!
 * Harriers for the cup!
 * Note that Cain himself has charged in battle yelling Waaagh to throw his enemy off: First in the short story Traitor's Gambit, then in The Emperor's Finest.
 * As for the Imperium: FOR THE EMPEROR!
 * And the Tau: FOR THE GREATER GOOD!
 * The greater good...
 * Shut it!
 * Particularly notable are the Eldar Howling Banshees, whose shrieking, wordless battlecry is psychically amplified by their helmets to paralyse the enemy.
 * The list is fairly long considering the vastness of the universe.
 * To the extent were the Necrons and Tyrannids are seen as more terrifying because they fight silently.
 * Also the Legion of the Damned are considered scary as hell because they are wholly silent (aside from the sound of their guns)
 * Not to mention they appear out of nowhere, wearing black Power Armor decorated with bones and wield heavy weapons, as pictured here.
 * Dungeons and Dragons has multiple mechanics for this, the simplest being the Kiai Shout feat. All of them allow you to render enemies shaken or panicked by shouting at the beginning of battle.
 * Given the Truth in Television entry above, it probably isn't surprising that characters with the appropriate background in Deadlands can actually take a Rebel Yell as an Edge. But wait, weren't Native Americans known for their warcries, too? One thing that virtually any Native American warrior with his salt can do in the setting is a fast Ritual called "War Cry," which tends to earn favor with the War Spirits. Worth mentioning here because the Ritual has a higher chance to succeed if the player yells, too. What's that, you say? Role-playing? In a Tabletop Games? What are the odds?
 * Trollkin Fell Callers are born with innate vocal powers which are so strong they can deafen opponents within their immediate vicinity if they yell loud enough.

Video Games

 * Dead Space sees the otherwise-silent Isaac Clarke grunt, yell, and scream his lonely way through an entire army of undead monsters that used to be the USG Ishimura's crew. He does this because he's scared shitless and it helps him cope.
 * The character properties screen in City of Heroes includes a field labeled "Battle Cry".
 * Serious Sam has a unit called the Kamikaze Bomber. Despite not having a head it screams, continuously, from the moment it's created until it dies. It gets quite unnerving.
 * Or annoying, rather.
 * In the Mega Man X games after X7, X himself becomes one of these. Many of his dialogue sequences are also spent screaming at his opponents.
 * This is perhaps best seen in the final battle with Sigma in Maverick Hunter X, where X slowly goes from determined to WHY YES I'M ANGRY WHY ELSE WOULD I BE SCREAMING IN CAPSLOCK RAGE RIGHT NOW?! In English, you can practically hear the boiling blood of Domon Kasshu.
 * Grom Hellscream (pictured above), chieftain of the Warsong Clan from War Craft II and III. In a scene in one of the books, he makes an enemy drop his defences by screaming so loud it physically hurts him.
 * One of the reasons he follows Thrall is that Thrall was barely annoyed. His most memorable appearance in the game was doing this to a giant demon, and winning.
 * Bloodline Champions has the Vanguard bloodline, in which four of their nine abilities involves yellling.
 * Double H from Beyond Good and Evil. He charges into battle with a healthy CARLSON AND PEETERS! whenever he attacks, and he enjoys yelling in general.
 * While in Rage mode the Arbiter of Halo Wars will often yell: I AM THE ARBITER!, just in case you forgot.
 * The Elites are all basically this trope. Get close to a high ranking one in Halo 2, he'll drop his weapon, scream (while shaking his fists in the air), and draw his energy sword in an incredibly dramatic fashion. While swinging it, he'll yell variations of "Hiya!". The Arbiter in Halo 3 is even more so; get in a close-quarters fight, and it's guaranteed you'll hear a primal roar followed by the sizzle of energy sword on flesh.
 * Their UNSC counterparts, the SPARTAN I Is, are the absolute opposite, and it even manages to unsettle Thel 'Vadamee.
 * Grunts will scream hilariously ("Aiyaiyaiyaiyaiii...!") when they go nuts and kamikaze you. Most often drowned out by the player's "Oh Crap!"
 * Link, starting in OoT. After all, if you're going to pay Nobuyuki "Gai" Hiyama to play your Heroic Mime, you've gotta make use of his voice somehow.
 * Diablo 2's Barbarian has an entire tree of skills which involve roaring to either buff himself and his allies, or de-buff enemies. One of the highest-level war cries, simply called War Cry, deals direct physical damage.
 * World of Warcraft's Warrior Class takes a slice from the Barbarian, with multiple abilities relying on shouting for a similiar range of effects, although he can't directly deal damage with any of them.
 * Heroes of Might and Magic 5: Orc Barbarian Heroes have their own brand of magic, called War Cries. One of them deals direct damage by making all his units shout at an enemy.
 * Enja.
 * Hot-Blooded Sanada Yukimura from Sengoku Basara just will not shut up! No wonder we feel sorry for his voice actor...
 * Brick from Borderlands, while in berserker mode.
 * Scarface the World Is Yours has a lot of screaming. Various gangs scream en masse while charging into Tony's superior firepower. Tony can scream right back whenever the player wills. And of course, during the 'rage/invincibility' attacks the screaming is out of control (and foul).
 * Garuda, Garuda, GARUDA. Nine out of ten times, this guy will be belting out warcries at the top of his lungs. When he's not, he's either laughing or speaking in a creepily hushed tone, which might be even more unnerving. (Fun fact: Garuda is voiced by Osamu Hosoi, known for his portrayal of the Hot-Blooded Dan Hibiki up until Street Fighter IV.)
 * Minsc of Baldurs Gate, as befits his nature as a Crazy Awesome berserker.
 * Anders of Dragon Age II is a rare Squishy Wizard example. Being possessed by a vengeance demon which is driving you insane will do that.
 * In the first game, there's also Champion's (warrior's specialization/Prestige Class) War Cry ability, which (when upgraded) can literally make enemies fall down.
 * Asura is a new triumphant example for this trope, considering that he's basically the embodiment of wrath, a title that is in no shape or form undeserved in the slightest.
 * It got so bad that Liam O Brien in fact was reportedly spitting up blood from the recording sessions for the game's English dub. Dude's a trooper.
 * In Stinkoman 20 X 6, Stinkoman enters every boss battle (if he can get to the bosses) screaming "Are you asking for a CHALLEEEENNNNGE!?" In 1-Up's level, he screams "I wanna be the guy, too!"

Western Animation

 * Hawkgirl in Justice League. On average, it was about one yell for every swing of her mace.
 * Tell me that a woman with huge wings flying/charging at you with an indestructible mace of Nth metal isn't scary. I dare you.
 * Prince Zuko in Avatar: The Last Airbender
 * Sokka initially tries to be this in the second episode, but gives up on it once he realizes he's no match for Zuko. After some training, he's shown to indulge in it from time to time. He also tried to do a sneak attack on Aang from behind...whilst screeching "SNEAK ATTAAACK!!!" at the top of his lungs. He is forcefully reminded of the negatives of this trope.
 * Sokka's attempt in the second episode turns a comical few moments into something less funny when one considers how much he's trying to emulate the warriors who left home, i.e his dad Hakoda.
 * We also see the Southern Raiders all letting out a battle cry before attacking the Southern Water Tribe.
 * Who reply with ones of their own.
 * Shego of Kim Possible
 * Don't EVER hurt Nibbles or Jerry will invoke this trope, followed by plenty of pain, suffering, and Laser-Guided Karma.
 * Subverted in Invader Zim: Zim, being something of a Proud Warrior Race guy, attempts a badass battle cry but winds up with an irritating, high-pitched "eeeeeeeeeeegh" sound.
 * Anyone who saw G.I. Joe the Movie can guess who goes here. COBRA-la-la-la-la-la-la-la! Hey, it helps them fight...somehow.
 * Finn of Adventure Time.

Real Life

 * The infamous rolling, yipping "Rebel Yell" employed by Confederate soldiers during the American Civil War (not to be confused with the Texan yokel "Yee-haw!", by the way) was said to have chilled the blood of any Union troops that heard it. Scottish Highlanders and certain Native American tribes were also said to have employed similar-sounding yells in battle (and, since at least some Southerners had both Scottish Highlanders and Cherokees in their family trees, that last counts as a bit of Fridge Brilliance).
 * According to Ken Burn's The Civil War, the version we hear today is a pale imitation and can only be truly heard "In the heat of battle."
 * "Bannzzaaaiii!" or so the old Nipponese war cry goes. A harbinger of trouble for any ill-equipped, ill-fed and ill-led Chinese conscript low on ammunition - which was most of them, most of the time. Banzai charges were a perfectly valid tactic in China, as many partisans and warlord troops would break off and flee at the cry. It was not nearly so successful against professional Chinese troops, or Commonwealth and American soldiers when they got dragged into the war. Not because it was any less terrifying, but because they had decent numbers of machine guns and reliable supplies of ammunition for them.
 * Also "Totsugeki!!" (which literally just means "charge!")
 * Kendo, a Japanese martial swordfighting art, utilizes Kiai shouts before and during attacking, with the shouts before attack used to throw your enemy off-guard and help you concentrate yourself and the kiai during the hit to let others know that you are concentrating on your hit and are giving your best to hit it.
 * A similar but less formal practice occurs in Western fencing during attacks.
 * Any practiser of a hard style martial art (karate do, taek won do or similar) can devolve into this by using too many consecutive kiais. When used correctly, the kiai helps with focusing an attack, making it more powerful and more accurate, and startling the enemy. When used incorrectly, it becomes, well... silly.
 * In the "loud consecutive grunts" department, many tennis players are known for this. Especially the female ones.
 * Related is the "boxers' snort," which supposedly adds power to the punch.
 * REMEMBER THE ALAMO!!!
 * Aiyo Gurkhali ("Blood for the goddess of death. The Gurkhas are coming!")
 * Kiyaping is a regular part of most martial arts training, both for intimidation value and because (as mentioned above) breathing out increases the force of a technique.
 * And most of the armies would scream while charging, be it something formal, like "banzai", "charge", or Russian "Oo-rah!" (stress on the last syllable), or something individual for each soldier, collapsing into incoherent roar, for exactly same reasons: intimidate and focus one-self for a high-speed dash towards the enemy. Not so common now, of course, since full-scale charge is rarely performed.
 * OO-RAH!
 * At least according to the Romans the native British would often scream at the top of their lungs when attacking. Combine this with spiked hair, blue warpaint and the fact that they were usually half again as tall as the Romans and you can see why they made them nervous. Not that much use against actual tactics, mind you...
 * It's human nature to freeze when scared. The US Army teaches their trainees to use the "battle cry" and scream before making an assault, as this helps to "unfreeze" the soldier in question.
 * Taka, during the Let's Plays.
 * The Imperial Russian, Soviet, and Russian Army's deep bass Oo-rah! would qualify, but with as less of a scream and more of a drawn-out 'urraaaaah' sound. Stolen from the Ottoman Turks, apparently; it means "strike to kill!" in Turkish. Definitely a symbol of the Russian infantry for centuries; German WWII vets said one of the creepiest sounds you could hear was that mournful howling sound as a Soviet attack went in, regardless of whether it was directed at you or not...
 * Traditionally, each Scottish Clan would have their own battle cry, from Clan Cameron's "Chlanna nan con thigibh a so's gheibh sibh feoil!" which translates to "Sons of the dogs, come hither and you shall have flesh," to Clan Gordon's "A Gordon! A Gordon!" You can see why a rather large group of rather large men in kilts wielding broadswords and spiked shields, running towards you, screaming such things at the top of their lungs, might make you just a little less inclined to stand and fight.
