You're playing your favorite MMORPG, First-Person Shooter or other online combat game. You and your team have come up with a workable strategy to tackle a challenging opponent. It will require organization and good timing, but you're sure it will work if you get everything set up in advance... wait, did KillerMonkeyz548 just open fire? Congratulations, your brilliant plan has just been ruined in one move by a Leeroy Jenkins.

The Leeroy Jenkins (or just Leeroy for short) is a specific type of Noob who has no patience for complicated plans, preferring to charge full-tilt into the fray and start attacking whatever's in front of him. Since this is a semi-viable strategy some of the time (depending on what game you're playing and the difficulty of the opposition), a Leeroy can remain undetected until the team hits the first real challenge, whereupon his recklessness gets everyone killed. Any attempts to point out that he had totally ignored the plan will be met with words to the effect of "plans are stupid". And he will never retreat.

On the plus side, a Leeroy can sometimes be detected before they cause calamity when you see them utter (or type) words to the effect of "Hey, watch this!" In groups with experienced players, the phrase can be translated as "Immediately stop moving toward those enemies with very big guns and back out of Alpha Strike range because Sir Badassboi is about to do something incredibly stupid and attention-grabbing." Never attempt to save a Leeroy from the consequences of his mad charge; this will only encourage him, as well as provide repeated amusement — he will often attempt the exact same thing again when he's revived. Should the group somehow miraculously pull through, don't expect him to wait for you to recover; he's already charging the next target.

If your leader doesn't wise up and punt him from the team after the first couple offenses, he can become a real-life gaming example of The Millstone, ruining any chance you have of completing your quest or mission successfully.

The trope is named after a World of Warcraft video that has been made famous around the net. For more information, see Leeroy Jenkins Video.

"Stop being such a Leeroy" has become multiplayer jargon in the time since, and it's sometimes used as a verb "to Leeroy" meaning to act in this way. Ironically, the original staged video can be seen as sympathetic towards Leeroy in that it also mocks and parodies excessive planning in parties. Considering that many of the mistakes made by the group in their attempt to save Leeroy were part of the group's original plan, the implied point is that if you have a Leeroy Jenkins in your party, you probably deserve him. The exception is a Pick-Up Group... in which case you know what you're going to get.

If an A.I. character that you need to keep alive does this, you have a classic example of a bad Escort Mission.

Some players also use "pulling a Leeroy" to refer to rushing in heedless of your own safety even when this is a viable tactic. To

If, rather than being a Noob, the Leeroy is doing this purposefully to get a laugh out of disrupting the Serious Business that internet gaming has become, then he is a Griefer and should be kicked from the group posthaste.

Compare Attack! Attack! Attack!, The Real Man, Indy Ploy, and Strategy Schmategy. See also some Challenge Gamers. Not to be confused with avant-garde musician Leroy Jenkins or the sports columnist of the same name. Underequipped Charge is related, but a character may perform one out of desperation rather than recklessness. For other similar character behaviors, see Reckless Sidekick, Unwitting Instigator of Doom, and Fearless Fool, as well as some incarnations of The Berserker. This type of character may have been inspired from living with a Martyrdom Culture, or trying to perform a Zerg Rush by yourself. Contrast We Need a Distraction and Crazy Enough to Work. A Defensive Feint Trap is an attempt to bait the enemy into doing this. If he is on the road, it is very likely he Drives Like Crazy.

Of course, the most important thing to remember is that—


All right, time's up! Let's post examples! LEEROOOOOYYY!! JEEEENKIIINS!!

    open/close all folders 

    Anime & Manga 
  • Naruto:
    • Naruto gets called out on this when he runs off after Yukimaru by himself in the Three-Tails arc, with Kakashi and Yamato reminding him of the impact his actions could have had on the mission, and Sakura punching Naruto into the ground so hard he makes a crater. He gets the very description of a Leeroy Jenkins by Akatsuki, especially when Sasori asks Itachi to describe Naruto to him.
      Itachi: (to Sasori) The Nine-Tails is the one who screams and charges headfirst.
    • Eventually he learns to take advantage of the enemy assuming this to be the case. Even better than having a plan is having a plan while the enemy thinks you're too stupid or cowardly to have a plan, or it's so insanely reckless that it's Crazy Enough to Work.
    • Sasuke Uchiha, as the series progresses, also falls into this habit as ambition overrides normal thought and he begins to rely more on inherent ability than skill or strategy. He spent two pages explaining The Plan for fighting Killer Bee, and no one followed it. Not even him! Then he got about twenty times worse when he rushed the freakin' Raikage, a giant of a man who's basically a ninja in a wrestler's body.
    • Hidan notes that when a target angers him enough, he goes berserk, forgets about the plan, and kills everyone in sight. For obvious reasons this usually works. Usually.
    • Sasuke's immediate response to seeing Itachi in Part I was charge at him with a Chidori, and he spends the rest of the fight furiously rushing at Itachi only to get beaten down repeatedly. The first time they meet in Part II, Itachi (who turns out to be a genjutsu) mockingly asks if Sasuke is going to run at him screaming like last time.
    • Shino follows Sasuke (who's pursuing Gaara in a Leeroy Jenkins move of his own, albeit in a loose interpretation of Genma's suggestion to make himself useful) in the Invasion of Konoha arc and ends up fighting Kankuro, whom he was disappointed to not be able to face in his official match.
    • In the Five Kage Summit arc, Sakura put her teammates to sleep with a special gas to face Sasuke alone, which did not work well and required Kakashi to save her. She later charged into Kakashi's fight against Sasuke to kill Sasuke herself, only to hesitate at the worst possible time because she still loves him and caused Naruto to rescue her from Sasuke...which resulted in Naruto getting cut by Sakura's poisoned kunai.
  • Mazinger series:
    • Kouji Kabuto from Mazinger Z is a mild case of this. In one hand, he never listens when someone tells him "Don't go", he is impulsive and hard-headed, falls into utterly DUMB, anybody-could-have-seen-it traps because he is too hasty and eager (a fiact Kouji himself lampshades), and he is a determinator who doesn't know when to quit. On the other hand, he IS capable of listening and following instructions and plans, he is a Genius Ditz who is good at devising strategies on the fly, he is capable of deceiving the enemy and he understands that sometimes stealth is necessary and even good (although he is not very good at it, but at least he makes the attempt), and the wisdom of making a tactical retreat. And he is capable of acknowledging his mistakes (once he was forced to retreat. He was angry, but after The Professor Yumi explained the situation to him, he admitted he was wrong and apologized). In a nutshell, he shows some traits of the trope, but he has not let them get him killed.
    • General Scarabeth from Great Mazinger somehow manages to combine this trope with The Chessmaster. He is the best tactician of the Mykene Empire, capable of creating brilliant strategies and completing missions others had previously thought impossible. However he is also the more battle-thirsty commander, and he is prone to charging the enemy headfirst without waiting for his troops.
  • Rak from Tower of God. The test in question was designed so that one picked the right door. Koon is trying to work with what little clues they have been given, whereas Rak gathers that the scarcity of of clues was just another way of saying "Gamble!", so he kicked a random door down. This just proves how much of a fuck Rak doesn't give, since choosing the wrong door is penalized by death. Luckily, EVERY SINGLE DOOR was correct.
  • Misaki Yata from K, on several occasions.
    • Episode 2: Kusanagi tells him to avoid the Black Dog, because Misaki's no match for him. What does Misaki do?... yeah.
    • Episode 4: When they find out that the guy they're chasing is on the school island, Kusanagi remarks that it'll be difficult to get into there, and they'll have to "play it safe". At that point, Misaki's practically out the door already. Fushimi remarks in the next episode that he knows Misaki must have done this, because Kusanagi isn't stupid enough to send in just him and Rikio.
    • Then in the movie, Kuroh and Neko are surveying the tower where Anna is being held. Kuroh observes the guards in and around, and says "Only a fool would try to break in through the front." Cue Misaki.
  • Haruhi Suzumiya: In the Deep-Immersion Gaming episode, Haruhi is exactly like this. Kyon manages to talk her out of it until the middle of the battle, though.
  • One Piece:
    • Luffy has pulled this stunt as illustrated in this video. It also worked for him because he is easily the strongest member of the Straw Hats, and to his credit freestyle fights against the Big Bads rather well but it backfired in the Punk Hazard arc. Luffy charges in and challenges the Big Bad of the arc despite his ally Trafalgar Law's warnings and plans, resulting in the crew's defeat and almost everyone being captured.
      • Though to be fair, he was winning that fight. The Big Bad just pulled out a rather creative application of his devil fruit powers that took out everyone with even a modicum of significant strength in the vicinity. Once Luffy was aware of it the villain didn't stand a chance.
      • It's also backfired against him during his first few fights with Crocodile and his one fight against Magellan, both of whom were far above his level at the time of their encounter. Only sheer luck and his drive to survive allowed him to come away from those fights alive, and he only beat Crocodile because the latter threw away strategy in rage at seeing him come back yet again.
      • Subverted in two specific cases. Even Luffy knows that attacking Mihawk and Magellan (after he nearly died the first time) head-on is a very bad idea.
      • Badly backfires against him when he decides to take on Kaido after Law implored him to do anything other than what he wound up doing; Luffy whaled on him in Gear Fourth (something that was sufficient to absolutely crush Doflamingo), and the most he was able to do was sober him up. Once Kaido was stone sober, he knocked Luffy's ass out in one hit while he was still in Gear Fourth.
    • Sanji pulls a Leeroy Jenkins in the Water 7 arc, when he goes off on his own to look for Robin and does it again when he decides to rescue her from the CP9 after boarding the Sea Train, despite Zoro warning him over the Den Den Mushi about the CP9's strength; he says that he would not obey any order given to hold back now that Robin needs to be saved. Incidentally, Luffy approved of this approach, and told Zoro he would have done the same thing as Sanji and proceeded to do so as soon as they arrived at Enies Lobby.
    • Zoro does it too, much later in the Wano arc. Prior to their arrival, traveling Wano native Kinemon tells the Straw Hat Pirates to keep a low profile and try to blend in so as not to catch Kaido's attention. It does not take long for Zoro to get in trouble (for an unspecified reason) and sentenced to an execution, upon which he makes a break for it and slices everything and everyone in his way. Luffy arrives on the island later and meets Zoro—as both feel the need to pummel some enemies, they agree that they will cause trouble and apologize to Kinemon later. Luffy's ally Trafalgar Law happens to be on the island too, and upon hearing Luffy is on the island and charging headfirst into a nobility district, he has this exchange with his first mate Bepo:
      Bepo: Captain! We got trouble, captain! It's Straw Hat [Luffy] and Roronoa [Zoro]!! They're heading into Bakura Town!!
      Trafalgar Law: Straw Hat's in Wano?! Hey, wait! He's going to cause nothing BUT trouble!!!
    • Generally speaking, this seems to be the Straw Hats' standard unspoken battle strategy: let Luffy go after the leader/the strongest/the most important, etc etc. and while the top brass is busy with him, the rest of the crew split up and go on to tackle the underlings as well as take care of any smaller objectives during the battle. As noted above however, the success rate of this tactic varies; usually dependent on how cunning their current enemy is.
    • In a villainous example, Kaido's underling Jack has a well-established reputation for extreme and frankly suicidal impulsivity that never seems to net him anything good. His fondness for blind headlong charges and a complete refusal to back down even when he has literally no chance of winning has cost him, in chronological order, five days of valuable time and a very rare weapon (because he picked a fight that turned into a hopeless stalemate that ended solely because of said weapon), a good deal of his fleet and his physical wellbeing (because he got the shit beaten out of him by people who probably could have given his boss problems), and what little of his fleet remained after the last defeat plus his freedom (because he tried to fight an elephant the size of a country and naturally got sunk, trapped undersea but not drowning).
  • Tengen Toppa Gurren Lagann
    • Every Ganmen pilot is one of these, and Leeron and Attenborough also display some characteristics of the trope ("HASHAAAAAAA") but when you're in a universe where everything, especially physics, is subservient to the Rule of Cool, this is the best tactic.
    • Kamina was the most prevalent example of this trope, and the other characters tried to make it clear that this was a very bad idea. Sure, he inspired everyone, but if Simon wasn't there to level things out, Kamina would've been dead by the end of the second episode (a fact Kamina reiterates several times). Granted, Kamina later tells Yoko that this show of bravado was simply a show to inspire Simon, so in that respect, it may have been the most brilliant tactic of all. Unfortunately, the one time he plans out a strategy to capture Thymilph's Dai-Gunzan, it ends up being the death of him. The rest of the Gunmen pilots are marginally more level-headed, but still incredibly bold.
  • Neon Genesis Evangelion. Shinji and Asuka are repeat offenders:
    • Shinji charged straight at Samshiel despite his sliced off power cord, he was running out of power and out of ammo, and Misato was ordering him to retreat back to the base. He completely acted on impulse. Later he got arrogant and reckless and got himself imprisoned inside a 2-D Angel until Unit 01 went nuts and ripped itself out of its 3-D shadow.
    • Asuka jumped into battle with Gaghiel without equipment suitable for aquatic combat, although Misato took her side anyway (circumstances forced her hand). In the next episode, she tried to get the battle with Israfel over with early by slicing it in half, but it split into twins and trounced both her and Shinji. Finally, several episodes later, she launched herself out to shoot down Arael, only to fall victim to the Trope Namer of Mind Rape instead.
      • Given the circumstances however, Asuka can largely be argued as being exempt from this. In the aquatic battle, hers was the only EVA around and the only weapon effective against the Angel. With Israfel, she did the thing that would have worked on all previous Angels with no info regarding any changes. Finally, in her last battle, she was sent out by her superiors to yet again combat an Angel with unknown capabilities, resulting in said Mind Rape occurring near instantly.
  • Ash Ketchum from Pokémon is guilty of this. Despite having Pokémon to fight his battles for him, his solution to most problems upon first encountering them is to let out a Battlecry and launch himself at them headfirst. This is especially true in the movies. For instance, he ran at Mewtwo and tried to punch him (twice) in the first movienote , threw himself at the cage holding Moltres captive at the second, charged at Entei in the third, threw himself at the cage holding Latios in the fifth... and no matter how many times Ash tries to use Take Down, it always has no effect. In genuine Pokemon battles he often orders his Pokemon to take their opponents head-on instead of assessing what they can do (mostly in older seasons, as he's since developed his own brand of strategies that take advantage of the battlefield geography). Basically, Ash can be summed up with "way more guts than brains".
    • Some of his Pokemon end up like this, too. Not Pikachu - Pikachu's a lot more likely to think things through than Ash. Froakie, however, has even less regard for his own safety than Ash. He did get a bit better after evolving, but still tends to throw himself at things.
  • Bleach
    • Ichigo Kurosaki does it, but not for the sake of idiocy itself.
      • While he and Uryu were facing down the first Menos Grande to appear in the story. Uryu tries to formulate a plan, while Ichigo simply charges in with the intent of cutting it down, despite the damn thing being twice the size of a skyscraper. His plan was to chop the Menos apart piece by piece until its head was low enough to the ground that he could chop it. So it's less "no plan at all", and instead "there is a plan, but it's insanely stupid".
      • When Orihime goes to Hueco Mundo, Ichigo is told by the Soul Society to stand by and for now consider her to be defecting, but at least they won't specifically mark her death for awhile. Being the Chaotic Good personified he is, Ichigo gleefully ignored that order and bum rushes to Hueco Mundo to save Orihime, accompanied with his friends (later Rukia and Renji follows). This screws up the Soul Society's former plan to get all the Captains together and sent Byakuya, Kenpachi, Unohana, Mayuri and their respective squads to Hueco Mundo, which enables Aizen to lock them there.
      • Then there's when Ichigo charges blindly at Ulquiorra, who he thought was the top Espada at the time, just because Ulquiorra said he brought Orihime to Hueco Mundo. It ended badly.
      • In a fight against Ginjo, Uryu tries to tell Ichigo what he figured out about Ginjo's powers, but Ichigo gets bored, comes out of their hiding place and attacks Ginjo head-on. Ichigo is knocked back, and Uryu berates Ichigo for not listening to him. Though this time, Ichigo at least asked beforehand if Uryu had a plan, and only rushed in after he said he didn't. So...progress?
      • After a heart to heart talk with his father Isshin where he learns about Isshin's past and some important info about hollows and quincies, Ichigo looks to charge into action against the Vandenreich... until Isshin asks him if he even knows where he's supposed to go and how to get there. Ichigo gets embarrassed.
    • Maki Ichinose serves as a Leeroy Jenkins in the Bount Arc, as he decides to fight Kenpachi and settle his grudge against him for killing the previous captain of Squad 11 rather than preventing Ichigo and the others from pursuing the Bounts into the Seireitei.
    • In the Hueco Mundo arc, Grimmjow disrupts Aizen's plans by disobeying the order to stay in his chambers and going to save Orihime from two jealous Arrancar, having her heal Ichigo (whom Ulquiorra had left for dead), and sealing Ulquiorra away in another dimension, just so that he can fight Ichigo again. Defied during the infamous "Tea With Aizen" scene. Aizen was instructing the Espada about the invasion by Ichigo and his friends. In the middle, Grimmjow gets up and makes to leave, stating his intention to kill them outright, even though Aizen was not done discussing his plan. He rudely rebuffs an order to sit back down, and is then cowed into obedience by Aizen.
    • Yammy arrives at Ichigo's fight with Ulquiorra, smashing through the floor like the Kool-Aid man, and kills Loly and Menoly on a whim, thus releasing Orihime. He leaves almost as quickly as he arrives because of Uryu's landmine, then apparently kills Rudobon in the middle of his fight with Rukia. The damage his impulsiveness does to the villains' plans may not be all that significant in light of his being the 0 Espada.
    • Hiyori Sarugaki at one point charges Sosuke Aizen, only to be cut in half by Gin Ichimaru's Shikai (changed to her being Impaled with Extreme Prejudice in the anime.)
    • Kenpachi's battle plan usually goes as follows (comes with his insane Blood Knight tendencies).
      1. Allow enemy to strike you.
      2. Attack until they die.
      3. Find new enemy, repeat steps until bored or dead.
    • Candice Catnipp refuses to listen to her comrades and keeps charging at Ichigo even after he demonstrates he's much more powerful than her.
  • Death Note
    • Matsuda, wanting to be of some use to the investigation, goes off to investigate Yotsuba on his own. Unfortunately, at that time, L is in the process of formulating a plan to investigate them that he repeatedly stresses has no room for error or independent action. Matsuda hears a vague reference to killing people, gets caught, and forces L and the others to bail him out. L is annoyed by Matsuda's stupidity, but manages to turn this to his advantage in his longer-term strategy, especially when the time comes to trap Higuchi and Matsuda is chosen to appear on TV to lure him out.
    • In the climax to the series, Mikami deviates from the plan and takes out his notebook to kill Takada before the task force can find her, resulting in Near finding out where the real notebook is and making a copy of that, too, thus preventing Mikami from killing the SPK and task force in the climax. This was brought on by a spur-of-the-moment strategy that Mello used.
    • This tactic proves successful earlier in the series when Soichiro Yagami sneaks out of the hospital despite recovering from a (non-Kira-induced) heart attack, drives a police bus through the doors of Sakura TV's headquarters, and manages to stop the broadcast of the Second Kira's messages, despite L and the task force holding back after the second Kira kills Ukita.
  • In Yu Yu Hakusho, Yomi was a Leeroy Jenkins back when he worked for Kurama, often going on unauthorized and dangerous raids of his own, until he was eventually blinded in an attack that Kurama set up for him in an attempt to get him out of the way. He learned his lesson after that and developed into a calm, patient Magnificent Bastard.
  • In Super Dimension Fortress Macross, Hayao Kakizaki brags about how great he is during his first meeting with Hikaru Ichijo. But in combat, he turns out to be a Leeroy Jenkins, who rushes into battle leaving himself wide open. He ends up dying on a mission as a result. While Maximillian Jenius, who acts scared at first, ends up being a genius pilot.
  • Shana from Shakugan no Shana has great skill in fighting but poor skill in strategy. As a Flame Haze her plan to rush forward and cut the denizens to pieces. If not for Yuuji's support from the sidelines, she would have likely died a few times over.
  • Guts from Berserk, especially in his younger days, is very much a Leeroy Jenkins, but manages to succeed in that he's just that friggin' strong. Griffith, rather than try to rein him in, used his unit as a spearhead to disrupt, smash through, or otherwise destroy the enemy's front lines, which usually panic at the sight of him swinging his BFS.
  • Magical Girl Lyrical Nanoha
    • In the first season, Fate tries to extract the six unclaimed Jewel Seeds from the ocean using a spell. When there's a considerable reaction and the ocean itself seems to be attacking her, Admiral Lindy plans to stay back until Fate finishes and then go in and capture her, but Nanoha, who places higher priority on befriending Fate, intervenes with Yuuno to help against orders and leaves with half the Jewel Seeds. Lindy reprimands the two, but lets them off without punishment because things turned out well.
    • During the hotel attack in StrikerS, Shamal orders the forwards to hold the line against the gadget drones until Vita returns. Teana decides to go on the offensive and destroy the drones with a large Cross Fire Shoot, which almost hits Subaru. Vita saves her, but she yells at Teana for her reckless behaviour and at Subaru for trying to cover her up, ordering the Forwards to go back.
    • Signum, of all people, was guilty of doing this in the early chapters of the FORCE manga. Rushing into an opponent whose abilities are very dangerous against magical warriors such as her, without waiting for backup, without any upgrades (even worse by the fact that her abilities had weakened since the end of StrikerS, which takes place six years before Force) and without considering that the little info and measures she had about said opponent's abilities can be a bit inaccurate. She got horribly trashed for her troubles.
  • Naoe Kanatsugu from the Sengoku Basara anime. This is a guy who, upon discovering that the opposing side has deployed Honda Tadakatsu (aka the army's frickin' Gundam), decided that the best course of action was to take it/him on single handedly with no more than a standard issue katana — and naturally gets curb stomped. Maybe he thought katanas really could cut through tanks.
  • Two big ones in Utawarerumono. The first is Oboro, and in being a Leeroy he kicks off the events of the plot. He more or less grows out of this but is still very rash. The other is the emperor, who felt it would be a good idea to completely ignore his brilliant and highly paid general Benawi and start burning down random neutral villages, forcing them to side with Hakuoro. He doesn't get better, because this gets his country taken over and also gets an "assisted seppuku" for himself, courtesy of Benawi.
  • In the Fullmetal Alchemist anime, Wrath uses his alchemic powers to fuse with Sloth wanting to protect her. The problem? Wrath had also fused Sloth's weakness into himself. This allows Ed to finish off Sloth.
  • Sailor Moon:
  • Code Geass
    • Jeremiah Gottwald, upon hearing where Zero is during the battle of Narita, charges off to fight him, resulting in him being defeated and almost killed by Kallen's Radiant Wave Surger. In the Nightmare of Nunnally version of the battle, Alice goes after Zero, hoping to defeat him and be rewarded with a military or knight rank so that she can protect Nunnally.
    • Suzaku Kururugi also qualifies for this trope, in so much as military command structure will allow him to practice it. He always runs head-first at the enemy in order to defeat them. However, he is a Deconstruction of this trope because he knows damn well the likely result of it, and wants it to happen.
  • In one episode of Tokyo Mew Mew, Masha tries attacking the Monster of the Week in an attempt to prove useful, getting captured as a result and causing the Mew Mews to spend the rest of the episode trying to get him back.
  • In one episode of Durarara!!, Izaya and Shizuo, the latter known as Ikebukuro's "God of Destruction" Ware facing off with one another when a gang of thugs that Izaya had ticked off earlier come running into the middle of things. Upon recognizing Shizuo, they all immediately freak out, not knowing what to do. That all ends when one thug, out of pure fear, screams like a maniac and runs up to crack Shizuo over the head with an improvised bat. Cut to Shizuo punching the guy out of his clothes, then proceeding to Curb Stomp everyone else in sight.
  • In Mahou Sensei Negima!, Nagi Springfield turns out to have acted like this all the damn time; his first reaction to just about any threat is to charge blindly at it. As he's quite possibly the strongest person alive, it almost always works.
  • Dragon Ball
    • Son Goku typically works in this fashion, at least in the original Dragon Ball, where his plan usually consists of going off after an enemy that's hurt his friends on his own without any care in the world to whatever plan they might have set up, or in other words to simply pound people's faces in. This is most notably seen in the Red Ribbon Arc and especially the Piccolo Daimaou Arc, where Goku ignores a direct order from Master Roshi of all people to not rush off after the enemy.
    • In Z, he (and Piccolo) take this tack with Frieza, ignoring King Kai's warning against going off against Frieza. It's not as if they had the option of not fighting Frieza.
    • In the Cell Saga, after Cell becomes even more powerful than before, he kills Vegeta's son, Trunks. Gohan is the only person able to stand up to Cell's power... but Vegeta suddenly unleashes a vicious attack on Cell without warning. Cell promptly retaliates, beating Vegeta senseless, and Gohan has to save him from being killed; in the process, Gohan becomes severely wounded.
  • Black Star in Soul Eater, frequently as his direct approach (he is ostensibly an assassin) worked for minor threats, but not for big ones. He doesn't so much grow out of it as he becomes better able to face the situations he rushes headlong into. The recklessness and obstinate insistence on his own greatness remain.
  • Kimba the White Lion: Kimba can be a good planner when he tries to be and is usually successful when it comes to fighting, but it's a safe bet that he would rush out and attack/attempt to befriend the Villain of the Week and ignore the advice of his friends; this method cost him a few battles.
  • Digimon
    • Digimon V-Tamer 01 sees Zeromaru refuse to even let Yagami Taichi come up with a plan on two occasions. For the most part though, Zero fully expects Taichi to have a plan and follows them to letter. Daisuke and Takuya are worse. The former has to be saved by Taichi and Zero after picking a fight with a strange monster his friends said to avoid, the latter jumps into battle with an opponent he's told can't be defeated one on one.
    • Digimon Adventure: Taichi has always been an Idiot Hero, but he went through only a brief phase of this trope. Eventually the group came to the observation that a partner Digimon's tamer has to be in danger for them to evolve. So, as part of his increasingly desperate attempts to get Agumon to evolve to Perfect, he runs straight into the battlefield. It works and he quickly learns not to do it again for a DAMN good reason.
    • Daisuke is like this as well. It's notable in an early episode where Takeru and the others are thinking their strategy through, but Daisuke wants to charge in.
    • He is an association football (soccer) player and thus understands the importance of teamwork and sticking to roles to an extent, but Tsurugi Tatsuno of Digimon Next has an open disdain for "plans". This leaves the all of strategics to Yuu.
    • Masaru of Digimon Savers is an outright example, to the point of leaping off highrise buildings to punch giant mons. Apparently, that's how a man lives.
  • Natsu from Fairy Tail almost never pays attention to mission briefings and will rush off to confront the enemy alone. He also seems to have no concept of stealth. This attitude nearly gets him killed in the Edolas arc because he keeps forgetting that his powers don't work. What makes it worse is that the Tartarus Arc proves that he didn't learn his lesson from the Edolas Arc. Silver reminds him of why this is a bad idea.
    • After the second time-skup Natsu decides to try this again with the Avatar Cult... Granted he managed to put down 3 cultists, but once Gray showed up the others came back up and Natsu's in chains and cuffs.
  • It's observed in Pumpkin Scissors that no sane infantryman would attack a tank head-on, and much of the plot revolves around a project to create anti-tank infantry by removing soldiers' fear of pain and death. Yet Alice, who has no such conditioning, attacks a tank with a sword because she refuses to surrender to bandits and mercenaries.
  • Science Ninja Team Gatchaman. Although G-2 is supposed to be the team hothead, it's G-1, the Mighty Leader, who frequently rushes into a situation without thinking (or waiting for backup), particularly if something else is bothering him that day. It's particularly sad because when he really stops and thinks, he's very good with strategy and tactics.
  • Deconstructed in Aquarion Evol. Zessica Wong's actions in episode 18 end up getting Mix kidnapped.
  • Variable Geo: The trope is played with and averted, when Manami deliberately invokes it by pretending to charge blindly at Chihou to draw her fire. Manami sheds her dress at the last second to avoid being punctured, which creates an opening Jun to clothesline Chihou. Thus, ending the fight.
  • Judai Yuki from Yu-Gi-Oh! GX ends up pulling a couple of reckless moves in season 2 and 3 as his status as Indy Ploy-pulling ace is steadily deconstructed.
  • In an episode of Yu-Gi-Oh! 5D's, Jack Atlas was confronted by Ushio (who was Brainwashed and Crazy due to Rudger's spell), and because his arm was broken, needed Carly's help to duel him. Unfortunately, Carly became too excited, and quickly became somewhat of a Leeroy Jenkins, ordering Jack's monster to attack without asking him (which, as it turned out, was a bad idea). Fortunately, she quickly learned from that mistake - for the most part.
  • Even Yugi himself did this once in a very early episode of the original series, where the Evil Spirit that had possessed Bakura first made his presence known, and it was a rather bad time to have done something so foolish; Bakura had sealed the souls of Yugi and his friends in their favorite cards, forcing Yami to use them as pieces in a Shadow Duel; Yugi got angry eventually, both from Bakura's taunting and Jonouchi calling him "puny" (compared to Yami) and recklessly directed an attack towards Bakura's set monster, which turned out to be an Electric Lizard. (Fortunately, he and the others wised up after that.)
  • Attack on Titan deconstructs this trope whenever it appears, with tragic consequences whenever a soldier charges off half-cocked. In particular, during his first battle Eren Yeager charges after an enemy in a blind rage and this leads to him being seriously injured as well as getting his entire squad Eaten Alive. The second time he charges off without thinking, it gets him soundly beaten and nearly kidnapped. Levi is injured in the process of rescuing him at a time when the military cannot afford the loss of their best soldier on the front lines.
    • Ironically, in the Female Titan arc, Eren not pulling this for once leads to the death of Squad Levi.
    • Gabi, a Child Soldier of the Marley military's Tyke Bomb training program does this during a war against the Middle East allied forces. She constructs a grenade before approaching the enemy and throws it in order to blow up their armoured train, which also has a gun on it. It works, but she then ends up in a spot of trouble. Falco, one of her fellow soldiers, attempts to help her, only to not be any use — they're both then saved by Porco Galliard, the Jaw Titan.
  • In both A Certain Magical Index and A Certain Scientific Railgun, Gunha Sogiita's philosophy is to charge into situations without hesitation and punch any bad guys in sight, relying on guts to power through. He even brushes off people trying to explain the situation to him.
    • This isn't even the worst of the characters - Mikoto tends to charge in headfirst and expect to win (justified, she's one of the most powerful characters in Academy City), Accelerator didn't even bother learning how to fight, and the main character Touma's plans usually either start out as "punch it until it agrees with me" or boil down to such. Honestly, half the characters rely on their power and Leeroy right into battle. Granted, they usually win, but when they don't it ends about as well as the original.
  • Puella Magi Madoka Magica: Mami Tomoe of all people proves to be this, as she dies minutes within announcing she would "finish this Witch off quickly", taking up a more reckless, up-close approach to fighting, rather than from a safe distance as before. Also counts as Too Happy to Live, as all of this is on the heels of she and Madoka pledging to become partners in Witch-hunting, and a monologue about how great she feels knowing she won't be alone any more.
  • The protagonist of Cross Ange has one plan: charge right in towards the fray, much to the frustration of her allies. She's skilled enough that it works for her but their source of income is from the number of kills the individual makes. Tusk comments on her lack of stealth while monitoring her during her rescue mission in episode 9, and Julio, who ends up capturing her, criticizes her for being too predictable.
  • This is what kicks off the events to Mobile Suit Gundam: three Zaku pilots are told to investigate rumblings in Side 7, but they get it in their heads to start wrecking things once they find out what's going on. End result is getting their asses kicked by a 14 year old.
  • Panzer World Galient: Jordy is too Hot-Blooded, rash and loud for his own good, he's unable to be stealthy, and he feels more comfortable charging the enemy head-on than infiltrating an enemy base.
  • Delicious in Dungeon: Chilchack discovers a trap-laden shortcut, and asks to go first to scout out the safest path for the party to walk. Senshi impatiently tries to walk across the floor and triggers several traps that almost get him and Chilchack killed.
  • Soul Hunter: Nataku, especially early-on. He pick the strongest opponent, and attack head-on. No strategy, no battle plan, and he keep attacking head-on even when it does'nt seem to work. He not only doesn't wait to listen to the plan before attacking, but will even try to blast Taikoubou if he try to come at him to tell him the plan, because he don't wan't anyone interfering in his fight. He can go through with it because he is freakeashly strong, and able to survive anything, including losing limbs or being crushed into pieces, as long as his core is not damaged. Taikoubou still had to trick him into following a plan on one or two occasions, though.
  • In My Hero Academia, Bakugo starts out as one. It's not so much that he's dumb as that for most of his childhood he'd been a Normal Fish in a Tiny Pond, and when coming to UA, he began facing off against students who were capable of defending themselves against him and using his reckless thinking against him. He gets over it and starts thinking tactically after Izuku gives him a hard reality check by beating him in a teamwork exercise by exploiting his running off and abandoning his partner.
    • Deku himself, surprisingly for one as strategically-minded as him, will Leeroy up against anyone or anything if it means protecting others. Notable example include attacking the sludge villain who was holding off multiple Pro Heroes (before he had powers, mind) to save Bakugo, and against Muscular to save Kota. Apparently this attitude is common among Hero origins.
  • The Greatest Magicmaster's Retirement Plan: In the second volume, the students of Alpha's Second Institute are supposed to hunt weaker Fiends near the barrier as practice, but some overestimate their ability and attempt to exit the designated area to hunt stronger Fiends. The principal, Sisty, predicted this and organized squads of more experienced students and Magicmasters to reign in the new students. While no one dies, some of the students got traumatized from nearly being killed by stronger fiends and lost the ability to use magic.
  • The Hero Is Overpowered But Overly Cautious
    • Rosalie Roseguard marches herself and her soldiers into the nest of powerful fly demons without any strategy, resulting in many of her soldiers getting killed. The Hero, Seiya, is not impressed with her disregard for the safety of herself and her soldiers in her pursuit of honor.
    • Seiya himself was once an example of this trope and chafes with Rosalie because she reminds him of his past failures. During his journey to save Ixphoria, he pushed himself and his party to defeat the demon army as quickly as possible without caring about strategies or training. He ignores Aria's advice to take the time to research about the Demon Lord, and subsequently gets killed when he has no way to deal with the Demon Lord's self-revival skill. When he's summoned to save Gaeabrande, he uses more cautious methods in order to avoid repeating his mistake.

    Audio Plays 
  • In Horrible Histories, Richard III becomes this, immediately jumping into the war of The Battle of Bosworth against Henry VII after they have a slang match. Unsurprisingly, he is betrayed by some of his army and dies on the battlefield, leaving Henry Tudor to revoke his dignity by hanging Richard's naked body on a horse on a parade float around England.

    Board Games 
  • Chess
    • The Scholar's Mate is a version of this, which involves bringing out the queen and bishop to try to checkmate the opponent in the first few moves. It's popular with beginners, but any experienced player can easily fend it off and get a much better position.
    • Another popular tactic amongst inexperienced players is a form of blitzkrieg, attacking any target of opportunity that presents itself. While often unsuccessful at winning the game, the random movements make it difficult (if not impossible) for the opponent to accurately predict what move will be made next, making a counterattack difficult to formulate.
  • Backgammon: Do. NOT. Be. This. Kind. Of. Player. Rushing toward an easy jump is more often than not a surefire way to lose a game in which your luck depends on a roll of the dice.

    Card Games 
  • Magic: The Gathering:
    • There are many creatures that say "this creature attacks each turn if able", which essentially makes them Leeroy Jenkins, and a few other cards that let you turn your opponent's creatures into Leeroy Jenkins.
    • In a similar vein, several creatures (normally black and/or red) read "this creature can't block", making it more practical to constantly use them to push for damage and hope to force trades.
    • A particularly notable card is "Lust for War", which has your opponent's creature go all Leeroy Jenkins, and whenever it taps (which it usually does when attacking), it does three damage to its controller. Red is generally the color of rage.
    • A Red Burn deck uses this concept for the player. It essentially is filled up with a lot of direct damage spells, and hopes that you draw enough of them to kill the opponent with sheer momentum. The problem with this deck is, no matter what, the game will likely end on Turn 6; either they kill the opponent with their spells or die from the inevitable counter attack, since burn decks seldom have any creatures to actually defend the player.
  • The Yu-Gi-Oh! card game has a few cards of this type.
    • Berserk Gorilla, for instance, must attack if at all possible, and Battle Mania, a trap that Yusei once used, forces all of your opponent's monsters into attack mode, and forces them to attack during the Battle Phase.
    • It also appears in card lore. Enishi is often mocked for his recklessness. As a result, Enishi is known as "The Daredevil". Since he knew Shi En when they were part of the "Legendary Six Samurai", he ended becoming "Shien"'s Chancellor because Enishi is not intimidated by him.
  • World of Warcraft Trading Card Game has Leeroy Jenkins as an actual playable card. It used to be the page image. His effect caused your other allies to be unable to attack, and he could attack the turn he came into play if you yelled his name.
  • Hearthstone: Heroes of Warcraft:
    • Leeroy Jenkins returns as a card for this game, complete with Chargenote  and summoning two Whelps for your opponent that are enough to kill him off next turn. His inclusion is actually a subversion however: Leeroy originally is 'breaking a planned tactic by charging blindly like an idiot', but in this game, if you don't want him to attack, then Leeroy will not attack. He's actually most often used as a finisher in Aggro decks thanks to his high damage, and is considered a very powerful card. This is one of the times where Leeroy will obey orders and plans perfectly.
    • The various ogre minions from Goblins vs Gnomes can be this thanks to their Forgetful mechanic. 50% of the time they attack the wrong target, which can mean they go right for the opponent's face and leave a dangerous minion in play. Mogor the Ogre takes this Up to Eleven, since he gives the Forgetful effect to every minion.
    • Kobold Barbarian is this to a tee, since it always attacks a random target at the start of the owner's turn.

    Comic Books 
  • Hilariously lampshaded in Runaways. After Chase runs screaming into battle, Victor actually says to Gert, "You and Old Lace go after Leeroy Jenkins."
  • Ares, Marvel Comics' God of War, once pointed out a list of things like "white flags, taking prisoners, Geneva Convention thing and checking out if you have enough bullets before rushing into the battle" and concludes that those are things his sister Athena cares about. He's the God of War. To be fair, he is the God of War as in "conflict", and Athena is Goddess of War and of Wisdom, i.e. strategy. So it's in character for him; less in character for Athena to care about Geneva Convention and white flags, considering the original (Greek) myths. She probably doesn't; Ares, being Ares, probably just assumes that everything in war that he doesn't like must be her thing. This characterization is true to their mythological depictions...which is why Athena routinely handed Ares his ass when they were fighting on opposite sides.
  • Mark Waid once wrote that The Avengers' Battlecry is "Avengers Assemble". The Fantastic Four's is, "Johnny, wait!" due to hot-headed Johnny Storm's tendency to FLAME ON and barrel forth recklessly against whatever villain the team is facing this time.
  • The Flash: Impulse used to have this as his primary character trait. Justified in that he was raised in a computer simulation, and basically saw the world as a big video game without long term consequences.
  • Superman:
    • War World:
      • Discussed when Supergirl wants to find the eponymous Kill Sat and smash it and Superman warns her against being overconfident, insisting that "It's better to be safe than slaughtered".
      • The Spectre's test concludes when Superman realizes his acting without thinking has made things worse for many people.
        Superman: See what? A mindless, rampaging monster? A creature who acts without thinking or... or... Oh. Of course. I... See. I've been thinking with my heart instead of my head! Forgive me, Spectre — I've been acting like a fool!
    • In the storyline Panic in the Sky!, New Gods Orion and Lightray have come to Earth upon learning that Metron's Mobius Chair had arrived there without Metron. Superman had already guessed that Metron was captured by Brainiac and wants the New Gods to hold back and come up with a plan. Orion brushes him off, telling him they don't have time for plans, and the two race off to Warworld. Sure enough, the two New Gods get their asses handed to them by Maxima and the brainwashed Matrix Supergirl and join Metron in captivity.
    • In one Superman/Batman issue, the World's Finest are faced against "Doomstroke", a Fusion Dance of Doomsday and Deathstroke The Terminator. While Batman is wracking his brain trying to figure out what they should do, Superman roars, "We don't have time for strategy!" and punches him, knocking out one of his teeth. Fortunately, this causes Doomstroke to retreat.
    • Subverted in an issue of Trinity (2008). The heroes are sent to the Mirror Universe, and decide to liberate it. While Batman and Wonder Woman are trying to come up with a plan, Superman storms the Crime Syndicate's base. At first, the others think he did an idiotic move, but Supes beats them all and delivers their unconscious bodies. Superman explains that he deduced that the evil counterparts had grown complacent, as they had been ruling their world without any challenge for years. Also, as they killed their enemies right away, they never developed any real combat experience, while Superman did, since he always fights enemies who have an intent to kill him over and over again. It also helped that he, Batman, and Wonder Woman had had a mind-link put on them that allowed Supes to draw upon their skills and abilities.
  • As Deadpool once said: "F**k plans."
    • He also used this trope at one point, yelling "LEEROOOY JEEENKIINS!!" while he charges against his enemy.
  • Subverted in Asterix as the Gauls don't need to plan their attacks on the well-disciplined Roman legions — they can just charge right on in and win the fight. Played straight on occasion with over-eager Roman troops who think it'll be a piece of cake to take down a handful of undisciplined Gauls. Especially Obelix in Asterix the Legionary. "We CHARGE!"
  • Assassin and marksman Deadshot in the DCU sometimes acts like this. Somewhat explained by the fact that he has a death wish (or more accurately is apathetic about death). He can follow a plan, but if he sees his shot open, he'll take it without hesitation. Several suicide missions have been cut short by Lawton killing their target while the rest of the team was in the planning stage.
    Deadshot: Is there a plan here, or do we just shoot things at random?
  • Groo the Wanderer often does what Groo does best, i.e., charge in mindlessly and lay waste to everything he sees. To be fair, Groo is so good that he usually doesn't really need to plan, and so dumb that he'd probably just mess things up if he tried, so "attack first and think about it never" quite possibly is the optimum strategy for him.
  • Green Arrow can be portrayed like this in team books, especially when played against a more level-headed character.
  • Batman: "We need a plan of attack!" The Creeper: "I got a plan... ATTACK!"
    • Jason Todd (Robin #2) was prone to this. Most notably in the beginning of A Death in the Family when Batman is trying to plan an attack on a group of thugs below but Jason charges in before Batman realizes what's going on.
  • Woodrow "Woody" Van Chelton of Quantum and Woody, whose solution to nearly every problem is to jump in with guns blazing.
    "Plan schman. Beat the crap out of 'em while yelling a lot. It's in every movie."
  • X-23:
    • After Avengers Arena makes a point of reminding the audience that X-23 is a very strategic fighter, to the point that her brain is constantly taking in her surroundings and formulating the best plans by which to kill someone, in issue #10 she blindly charges right into a fight with Apex, and ends up beaten within an inch of her life for her trouble.
    • The trigger scent invokes this on her: Under its influence she falls into a berserker rage during which she has no control over her actions, and will blindly pursue anything contaminated with it, even if they're a friend or loved one. Laura has no more time for plans in this state, the only thought she has until the rage passes (usually after the target has been reduced to a pile of meat confetti, or until the trigger scent wears or can be washed off) is "Kill!"
    • However Laura can fall into this even when she's not grabbing the Idiot Ball or under the effects of the trigger scent. Situations in which she lets her emotions get out of control can lead her to acting rashly and without thinking. For example, she nearly got herself and Hellion killed by the Facility when she blindly rushed off on a rescue mission when Mercury was kidnapped while they were hanging out at the Grind Stone. A chance encounter with one of Zebra Daddy's former goons while on a night out with Jubilee drove her into a rage in which she not only assaulted the man in the middle of a crowded club, but sent her on a reckless mission to tear apart their sex trafficking organization and rescue the girls they were moving. Black Widow herself, while cleaning up the aftermath, pointed out that she was acting on emotion, not with her typical deliberateness.
  • A page from The Halo Graphic Novel has an L. Jenkins charging into the enemy while screaming, as a plasma grenade barely misses his helmet, and his squadmates are all staring at him.
  • Ultimate FF
    • Namor does not care and does not wait for anyone.
    • Stark checked if Rick's portal worked. Yes, it did, but... Doom does not want to listen, and goes, while Stark cries "I said, 'But...'!". So they all had to follow him him ASAP, before he gets blown up to pieces.
  • In Hunter's Hellcats, Cracker is the one most likely to jeopardize the mission by disobeying orders and doing whatever the hell he wants, such as firing at a Japanese plane and giving away their position.
  • This trope is discussed in Spider-Geddon. In the Peter Parker, the Spectacular Spider-Man tie-in, Peter defeats Morlun for the fourth time and gives him "The Reason You Suck" Speech stating that he shouldn't have lost four times in a row but instead murdered him in their first encounter. He points out that the reason he keeps losing is because of this trope, because he believes his superior abilities and his so-called "birthright" means he doesn't need to plan for anything. Instead, when his ass is handed to him, he's confused and infuriated that he's lost.
  • The Legend of Wonder Woman (2016): Lita Little tends to jump in head-first even if it derails her group's current plans. Upon arriving in France the first thing she does is decide to take a light tank for a joy ride, causing a fire on a military base which—as a furious Lawrence points out—could have been much, much worse.

    Comic Strips 

    Fan Works 
  • Chasing The Shadow lampshades this during the Zabuza fight scene, the narration flat out stating that Naruto and Sasuke's acrions were stupid and suicidal.
  • In the Worm/Gamer crossover Co-op Mode, James does this when he and Taylor end up overhearing Lung's plans on attacking the Undersiders. Amusingly, this leads him into getting a <Fool's Act> skill.
  • The Child of Love: In chapter 7 Asuka gets to offer tactical advice during a battle. Unfortunately she tended to rush into an unknown situation and losing her temper. Fortunately, when she calmed down she came up with a good strategy.
    Asuka:"Why not rush towards that damn Angel?!"
    Misato:"Do you know the meaning of the word 'caution'?"
  • This Chapter from the Disgaea fic Disgaea: Jewel of the Gods shows that busting through fortresses, with no strategy at all, is the one thing Laharl and Adell agree on.
  • In the Good Omens Manchester Lost fanfic Manchester Lost by JA Moczo, the archangel Michael is one. While the party is trying to sneak quietly into Hell to rescue a captured comrade, he begins by attacking the first (non-threatening) demon he sees. Crowley (the Noble Demon / party leader) deadpans, "There goes my next raise... [and] thanks to John Wayne here we just lost the element of surprise for absolutely no reason, because demons don't permanently die in Hell." Michael also attacks the Cerberus by himself, despite having the other Archangels as backup. And when faced with an entire army of demons, he walks up to them (again alone) to the tune of "You're the Best." And when Lucifer Ascends into a gigantic monstrosity of evil that is making reality disintegrate, what is his response? "Awesome."
  • JoJo's Bizarre Adventure Abridged
    • "Now that we're in Dio's lair, we should think of a plan to—" '''"KOMBAT TIME!!!"''' *smash*
    • Done more literally earlier in the series (Episode 6):
    Joseph: (in his mind) Nobody... make... a sound—
    Jotaro: LEEEROOOOOY!!! (charges)
  • The players in Sword Art Online Abridged often display this behavior, despite the fact that they'll die if their characters do. This even exasperates the guy who trapped them in the death game in the first place.
    Kayaba: Do you know how many of you have died while screeming "Leeroy Jenkins?!" More than zero! Which, as far as I'm concerned, is grounds for exterminating the species!
  • Allright, I'm to confront Cersei, Eddard Staaaark!
  • In A Cure for Love Light of all people does this. When the taskforce are faced with a crazy that's waving a gun around and is also holding onto a Death Note, Light forgets their previous strategy session and just lunges for it. Semi-justified in that his memories are wiped at the time and so his reaction is somewhere along the lines of "My precious" — he doesn't understand why, but he really wants that notebook.
  • Subverted in Point of Succession because Light and Matt's reckless charge into Beyond Birthday's villain lair really is all part of the plan. Played straight later when Matt learns that Mello killed Near and that he's still in the building. Matt just runs off searching for him, with no plan other than to somehow find him so he can punch him in the face.
  • A section of the audio from the original Leeroy clip was used for the scene in PONIES The Anthology II.
  • In Little Black Death Note Snape, Draco, and Blaise Zabini get into trouble while Dungeon Crawling and they just blast a wall with magic without checking for traps first.
  • Hivefled: Lereal Belsai plans to attack the entire Alternian fleet with his two-hundred-and-fifty cultist followers, most of whom are Child Soldiers or suffering from cull-worthy disabilities, relying on protection from Karkat Vantas' powers as the Second Sufferer. Karkat does not have any powers and is not pleased that Lereal doesn't believe him.
  • Used in a couple different ways in Game Theory. While Nanoha does come up with plans in combat, even if they are insanely reckless plans, this is essentially her approach to using magic, which doesn't work out too well for her in this setting.
    • Mei, on the other hand, doesn't really think things through at all, and just charges straight at her enemies, on one occasion forcing Chrono to let their enemies escape in order to save her. This is revealed to be the result of descent from a berserker lineage, which leaves her with almost no fear response and a consequent inability to gauge the results of her actions.
  • In the remake of Yu-Gi-Oh! The Thousand Year Door, the Shadow Queen, by her own admission, made a mistake like this which cost her the original battle a thousand years ago, charging recklessly into what was an obvious trap set up by the Dragon Master. She nearly makes the same mistake again in a crucial part of the duel with Andy, but remembers the previous incident at the last minute, and reconsiders; this small reconsideration lets her win the duel. (And a powerful lesson on why a Leeroy Jenkins is a bad thing.)
  • In the Worm fanfic, Intrepid, Aisha in 6.09, rushing in while Sophia was trying to get them protection from an enemy's power. This ended up with her falling for Benjamins' power since she didn't listen and trying to kill Sophia.
  • Ghosts of Evangelion: Thirty years after the fact, Asuka thinks the Fifteenth defiled her because she was too eager to fight it.
    Asuka: Get one thing straight, kid — I hurt myself there. They had no control over the Evas, and I wasn't even supposed to sortie that day. I'm the one who jumped into battle, and I'm the one who refused to retreat. Misato ordered me to pull back, but I wouldn't listen. I don't like admitting it, but what happened to me that day was my fault.
  • In The Last Son series, this is essentially the reason for Zod's defeat; while he is a tactical genius, Zod became so used to relying on his powers putting him above all of his potential opponents on Earth that he was unprepared for the heroes to catch him in a trap that drained his body’s solar energy reserves, bringing him down to a strength level where the heroes could more easily oppose him, particularly after they exposed his duplicity to Sentrius.
  • In Thousand Shinji, Asuka charged Israfel unthinkingly and hastily, and the monster beat her in humilliating fashion. After that battle and a little mentoring from Shinji, she became more prudent and cautious before engaging the enemy.
  • Children of an Elder God: During her first deployment, Asuka lost her temper and ripped an Eldritch Abomination apart. Later on, Gendo criticized her actions, stating that fighting like an enraged berserker would get them all killed.
  • Last Child of Krypton: Subverted. Asuka tried to behave as a disciplined soldier and retreat when she was ordered… but when Shamshel’s whips impaled her mecha she went mad and tried to kill it there and then.
  • Once More with Feeling: In her second battle, Asuka carelessly charged head-on, ignoring Shinji's warnings. Thanks Shinji she avoided getting her butt handed to her, but she still acknowledged and cursed her own recklessness.
  • In The Unfantastic Adventures of Bizarro No. 1, Bizarro repeatedly states he isn't a smart fighter... as proven by his first plan to engage the Blue-Kryptonite Man: a full-frontal attack, complete with a savage and ridiculous war cry. He wasn't even wearing any sort of radiation-proof gear, and got knocked out very, very quickly.
  • After the fact in Waking to Another Sky. Colonel O'Neill's stubborn refusal to believe that any video game could require tactics more complicated than "hit the monster until it dies" gets him labelled Leeroy Jenkins by the SAOvivors.
  • While not a plan so much as capitalizing on an opportunity, Dumbledore in Wind Shear interrupts a battle between Harry "Storm Chase" Potter and Voldemort's forces, assuming it to be a simple duel between Harry and Voldemort, which allows the latter to escape. When Dumbledore tires to defend his actions, citing that he didn't know what was going on, everyone present argues that he should have asked one of the bystanders present rather than apparating between the two and throwing up a shield.
  • Your Prince Is in Another Castle: Miia tends to charge headfirst into a fight, which often gets her into trouble.
  • In Worm crossover Echoes Of Yesterday, Kara rapidly gains a reputation of being an impulsive and reckless hero who gets into fights which she should stay away from.
    Colin Wallis, or as most of the world knew him, Armsmaster, had had a long day. Though he was no stranger to the chaotic nature that was the norm for the city, that day in particular had tested his patience. Several brief eruptions of gang violence, a fire that had threatened to burn down a good chunk of the downtown district, and a new cape that seemed to employ 'leap before you look' as a personal philosophy.
  • In Mars vs. Jupiter as Told by Mina, Lita's biggest challenge was to control her overwhelming rage with Raye, and think clearly.

    Films — Animation 
  • The Monsters vs. Aliens DVD includes a bonus feature of a storyboarded Leeroy Jenkins scene. It mentions Leeroy Jenkins by name. You've gotta love B.O.B.
    Dr. Cockroach: B.O.B., you idiot!
  • Sulley charging for the flag during the library challenge in Monsters University, after he grows impatient with Mike's attempt at stealth.
  • In Kung Fu Panda 2, Tigress has ordered Po to stay put in the dungeons because she knows that it's too personal for Po. What does he do next? He rushes headlong into the factory against her orders, inevitably screwing up the Furious Five's plans to blow up the factory along with Shen and his wolves inside it.
  • The Adventures of Ichabod and Mr. Toad: In the Wind in the Willows segment, the animals try to be quiet while sailing to the secret entrance to Toad Hall lest they alert a weasel guard of their presence. Toad, however, tries to shoot the guard, and they barely end up being spotted.

  • The Hobbit: The Battle of the Five Armies has a positive example. When hordes of Orcs show up, the Elves and Men have a Heroic BSoD, but Dain Ironfoot's troops get in between the Orcs and other forces and start killing without a second thought.
  • The Town ends with an example of this. The bank robbers have dressed up as paramedics. They take their loot to their getaway vehicle, which is an ambulance. SWAT teams have assembled and haven't recognized them yet. The ruse is working. They're about to get away. And then one of the robbers fires an M-16 through the ambulance window. Cue most of the bank robbers getting killed.
  • In Shaun of the Dead, Diane's boyfriend David is killed by zombies from the window. She grabs David's detached leg and uses it as a club as she charges into the zombie horde. (She also opened the front door, allowing the zombie horde to attack her other friends inside.)
    • The extras reveal that she survives, but it costs a man's life.
  • Star Wars
    • Episode II: Attack of the Clones: Anakin and Padme rush to Geonosis to rescue Obi-Wan, only to be captured themselves.
    • Also Jango Fett during the battle of Geonosis. When he sees Mace Windu drop his lightsaber, he immediately dives into the battlefield without thinking and it gets him killed, costing Dooku his best fighter and ultimately the battle. In his defense, Mace Windu embarrassed him in front of his son and his boss earlier which made Jango jump on the first chance he could get for revenge. For bonus points Count Dooku even has the look "are you serious, bro?" on his face as he does it.
    • Obi-Wan detailing a plan of attack against Dooku, which Anakin doesn't wait to hear before charging in.
      Anakin: I'm taking him now! (gets immediately zapped out by lightning)
    • Ironically, Anakin learns from that, and in Revenge of the Sith, actually listens to his mentor. Unfortunately, this results in the two of them being forcefully separated, and as a result, Anakin killing Dooku only causes him to sink worse into darkness.
    • Played straight in The Empire Strikes Back, when Admiral Ozzel's eagerness for battle results in the fleet coming out of lightspeed too close to the Rebel base, thus alerting the Rebels to the Imperial invasion. Needless to say, Darth Vader is not pleased.
    • Luke rushing off to face Vader at Cloud City without completing his training and over the protests of both Obi-Wan and Yoda.
      • This is echoed when Rey is put in a similar situation in The Last Jedi. When Rey realizes that Luke isn't going to help her, she decides instead to re-join the fleet to recruit Kylo Ren to the Resistance's cause, having sensed conflict within him. This goes VERY badly, as the entire scenario, the Force communications between Rey and Kylo included, was set up by Snoke in order to bait Rey into a trap. Rey only narrowly escapes with her life. Luke warns her not to go, having learned from his previous experience.
      Luke: This is NOT going to go the way you think!
    • Subverted in Return of the Jedi. When the Rebel team on Endor sees Paploo run off alone toward the shield generator, they think he's going to blow their element of surprise, but he actually creates a useful distraction by loudly stealing a speeder bike.
    • In A New Hope, Han charging a group of Stormtroopers on the Death Star. He actually managed to intimidate them into fleeing until they ran into a much larger group of reinforcements (much, much larger in the special edition).
  • Subverted in Sam Peckinpah's Cross of Iron. The two lead characters are about to mount a suicidal two man charge on the advancing Russian army when Stransky's gun jams and he can't figure out how to get it working again and Steiner collapses into hysterical laughter watching him struggling with the weapon.
  • Star Trek (2009): A brief "Leeroy" moment, when the Red Shirt pumps himself up for his fateful skydive onto the Romulan planetary drill.
  • In S.W.A.T. (2003), Jim Street and his partner Brian Gamble infiltrate a bank where robbers are holding hostages. They have an order to hold their position. Gamble breaks his "hold" order and attacks, killing the robbers but wounding a hostage, who sues the department for negligence. Through this could be a subversion in that it's clear the gunmen were about to kill the hostage, and if Gamble and Street had followed the hold order, the hostage would have likely died.
  • In Troy, Achilles pulls his own Leeroy-esque move as he attempts to take the beach of Troy with roughly fifty soldiers (several of which are immediately sniped by Trojan archers). All is amended when Achilles himself sets foot on the sand and promptly begins to run through the Trojan forces. After his brief exhibition of Nigh-Invulnerability, he proceeds to desecrate the statue of Apollo, and then throws a javelin about 200 Yards and successfully smiting a Trojan captain, and scaring the bejesus out of Hector.
  • The Year One DVD includes a bonus feature where the cast plays out the Leeroy Jenkins skit, complete with some of the dialogue from the original machima.
  • In The Bourne Ultimatum, reporter Simon Ross deviates from instructions from Bourne on eluding the agents out to get him, and rushes out into the open where a sniper offs him with ease.
  • In The Last Samurai Algren leads a newly-formed regiment in the introductory battle against the Samurai, who fight without firearms. The plan is to hold fire until the Samurai are within range and let loose. One soldier fires off accidentally, which the other soldiers mistake as the cue to fire their weapons, despite the commanders screaming to cease fire. Their volley's spent before they have time to reload and the Samurai overrun them effortlessly. One could argue that leading the inexperienced troops into battle earlier than expected (before Algren could finish training them) was a Leeroyish move by his commanding officer. Funnily enough, Algren served under (and survived!) notable real-life Leeroy Jenkins General George Armstrong Custer, and there are two points during the film he angrily points out he's no fan of the man and his suicidal tactics.
  • More fun with Custer: this is the general depiction of the man in Night at the Museum 2.
  • Ghosts of Mars: Williams charges headlong, both-guns-blazing into the crowd of possessed miners, resulting in the movie's first big shootout.
    "Come on, you mindless motherfuckers!"
  • In Rob Roy, a small group of Rob's clansmen are watching a large troop contingent burn a farm belonging to them. They see that the soldiers are too many to fight directly, so they prepare to draw back into the fog and continue to harry them. Then Rob's little brother Alisdair sees that the leader of the soldiers is the man who raped his sister-in-law. So he takes a shot at him from extreme long range and misses, which alerts the soldiers to the presence of the clansmen. Nearly all of the Scots are promptly butchered when the soldiers chase them.
  • Deconstructed to an extent in The Hurt Locker, where the adrenaline junkie main character insists his EOD team run into a series of darkened alleyways to attempt to find the insurgents behind a car bombing. Both of his teammates call him out on it, but since he outranks them, they have to go anyway. The ensuing firefight nearly gets one of them killed.
  • In Wild Wild West, West constantly ignores Gordon's planning and runs right into battle. Only after he causes them to run for their lives and runs out of other options does he ask for Gordon to work out a plan. Gordon doesn't take it too well.
    West: Gordon, what's your plan for getting this thing off my neck?
    Gordon: Excuse me?
    West: Well, that's what you're here for, right? You're the master of this mechanical stuff.
    Gordon: [chuckling maniacally] Oh ho ho, I see. Now I'm the "master of this mechanical stuff". As opposed to five minutes ago, when I was calmly and coolly trying to find a solution to this very problem. But then something happened. Someone, who will remain nameless — JIM WEST! — decided to jump over the wire, thereby providing us with that exhilarating romp through the cornfield, and that death-defying leap into the abysmal muck! And here we stand, with that demented maniac hurtling towards our President, with our one and only means of transportation, with Rita as his prisoner, armed with God-knows-what machinery of mass destruction, with the simple intention of overthrowing our government and taking over the country!
    West: Gordon, I think you need to calm down.
    Gordon: I can't be calm! Oh, no, no, no, no, I'm the "Master of the Mechanical Stuff"! And I have to help you! You, the master of the STUPID STUFF!
  • In The Untouchables Eliot Ness and the rest of the Untouchables plan to catch a member of Capone's gang midway through a deal with the assistance of the Canadian Mounties who are meant to wait for a signal from the feds before charging. Mid-deal, gun shots are heard as the Mounties charge anyway. Subverted, though, as they are able to achieve what they wanted to do.
  • Marvel Cinematic Universe:
    • The Incredible Hulk: Main villain Emil Blonsky is very much a Leeroy Jenkins; it's heavily implied that, in his eagerness to fight the Hulk, he prematurely springs an attack on Banner before sniper teams and other supporting units can properly get into position, causing Banner to transform into the Hulk before the military can subdue him. Also (he may not have hurt anyone but himself, but still): "That all you've got?" *THUD* Cue him having every bone in his body broken in about half a second.
    • Thor: Thor decides to gather his brother and his four friends and embark on a "diplomatic" mission to the realm of the Frost Giants. After a deal of tension, Thor turns to leave, but a giant calls him "princess", prompting him to send Mjölnir through his head at Mach 2. His friends have no choice but to join in the ensuing fight, and while Thor smacks the army around without even trying, Fandral is almost mortally wounded, and Odin exiles Thor for his lack of foresight.
    • The Avengers: Iron Man gives us this:
      Captain America: We need a plan of attack.
      Iron Man: I have a plan — Attack.
    • Despite the above example, MCU Steve Rogers has an occasional habit of this too. It's most noticeable in Captain America: The First Avenger, which features him dealing with the discovery that his best friend is a POW by invading Austria during a break in his USO show. Fitting his status as The Heart and The Good Captain, though, he's only reckless about his own safety and never surprises his teammates with this. When he does plan a head-on attack, he always gets some kind of prior approval from the people involved and does his best to make sure that he's still the one in the greatest danger.
    • Guardians of the Galaxy: Rocket is laying out a prison escape plan, and various things he will need. He mentions a "quarnex battery" which is mounted on the exterior of the security tower. He then explains that its removal will kick the prison into emergency mode, so they have to get it last. Groot, however, didn't hear that part. While Rocket is finishing up, he goes over to the tower, grows tall enough to reach the battery, and rips it from the wall. Everyone has to scramble. Fortunately for them, they succeed at escaping.
    • Guardians of the Galaxy Vol. 2: Drax leaps right into a battery-eating interdimensional monster's digestive system because its skin is too thick to be damaged from the outside and he thinks he can stab it to death from the inside. He can't. Peter and Gamora spend the next few seconds horrified and baffled that Drax would do something so stupid based on such faulty logic.
  • In the 2011 Three Musketeers movie, the title musketeers are trying to devise the best way to get through a booby-trapped hallway. While they are discussing, Milady just runs through it, narrowly avoiding all the traps.
  • Defied in Blazing Saddles. When Bart is told about Mongo's presence in town, he doesn't know who or what Mongo is, and prepares to simply go out and face him like Mongo was any other criminal. The Waco Kid manages to stop him before confronting Mongo, convince Bart that he can't take on Mongo like he was a common criminal ("If you shoot him, you'll only make him mad") and this gets Bart to stop and come up with a plan that plays to his strengths as a Guile Hero.
  • Used during the Battle of Manassas in Gods and Generals. The Confederates under Stonewall Jackson arrive on the scene. A couple of young guys tell their company, "Come on, we can take 'em!" and charge the Union lines. The rest of the company follows, with the commander basically forced to order a charge retroactively. Looking on, Jackson remarks that "it's good to get your dander up", but correctly predicts that the company will be slaughtered.
  • Colonel Thursday in Fort Apache, who's essentially an Expy of George Custer. Against orders he picks a fight with Cochise (who's willing to negotiate), then leads a cavalry charge into a well-laid Apache ambush. Needless to say, things don't go well. Thursday becomes a martyr for the US Army, with even his subordinate Captain York (who despised him while alive) claiming "no man died more gallantly."
  • One of the reasons why Gunnar Jensen was kicked out of the title team in The Expendables, the other one being his substance abuse problem.
  • In The Elite Squad, Nascimento is disappointed to learn that Neto is actually this once they carry out a real favela raid. He ends up having to bail the latter out.
  • Played with in Watchmen, in the 1970s flashback scene. The Watchmen are hovering above the anti-vigilante protest in the streets in Archie (their owl-shaped hovercraft), earnestly trying to calm down the crowd over a loudspeaker... and then the Comedian has to jump down to where the action is and pour fuel on the fire. Of course, pragmatically speaking, this wasn't exactly a foolhardy thing for Eddie Blake to do: it turns out to be not much of a fight at all, since the protesters have only rocks and beer bottles and the Comedian is an experienced CIA assassin toting major weaponry.
  • Diggs from Cats & Dogs: The Revenge Of Kitty Galore gets kicked out of the K-9 Unit because of not listening to orders, which results in a building blowing up. It gets deconstructed further as he also keeps messing up missions because of this, leading Butch to chew him out for his behavior and kick him off the team. This leads to Diggs maturing and putting aside his ego.
  • Raphael usually gets saddled with this role in various incarnations of Teenage Mutant Ninja Turtles, including the comics and the original 1990s movies. If the Turtles were a Four-Temperament Ensemble, Raph would definitely be the choleric one. His Hair-Trigger Temper, borderline Psychopathic Manchild impulses, and overall badass attitude make him the one most likely to either kick a serious amount of ass (good) or do something stupid and/or potentially fatal (bad). In the original 1990 film, he played this to the hilt and got himself temporarily knocked into a coma after falling through a skylight during a battle, although it was more a case of him being Achilles in His Tent.
    Raphael: [sarcastic] Oh, so that's the plan of our great leader — just sit here on our butts!
    Leonardo: I never said I was your great leader.
    Raphael: Well, you act like it sometimes.
    Leonardo: Yeah? Well, you act like a jerk sometimes! And this attitude of yours isn't helping anything!
    Raphael: Then maybe I'll just take my attitude and leave!
  • In the climax of Sherlock Holmes (2009), when Holmes and his allies learn of Blackwood's plan to murder everyone in Parliament with a remote control poison gas machine, he and Watson start coming up with a plan to get past the men guarding it...when Atler just starts shooting everyone.
    Watson: She loves an entrance, your muse.
  • In King Arthur: Legend of the Sword, Arthur and his gang spend days working and elaborate plan to draw King Vortigern out of his castle to a specific town in Londinium. Once they receive word the king will be there, they launch into more intensive planning on how to carry out an assassination and still safely escape the city. When the King's carriage arrives, they realize something is wrong. It's a trap intended to draw them out through their assassination attempt. Everyone agrees they should fallback. Except for their hotshot archer, Goosefat Bill, who has an axe to grind against the King's main guard. He shoots and kills the guard alerting all the king's men to their exact location, despite being explicitly told that doing so would cause them to be locked inside the city gates with no means of escape and surrounded by hundreds of men if they were unsuccessful in killing the king. Goosefat's action causes them to have to scramble madly about the city looking for an escape route and results in the murder of Arthur's best friend, Back lack, and the capture of Rubio, who confesses the secret living location of the resistance that is then slaughtered by the King's men. Great job, Goosefat.
  • In Danger: Diabolik, Valmont attempts to kill Diabolik without waiting for Ginko to give him the go-ahead and gets gunned down with 11 bullets fired from Diabolik's machine gun for the effort. Lampshaded by Ginko as he yells at Valmont for jumping in too quickly.
    Ginko: Valmont, don't play the hero!
  • In Baby Driver, when confronted with a horde of armed police, rather than take cover like her husband, Darling stands up in the middle of an open plaza and starts blasting away with Guns Akimbo. She gets blown away almost immediately.
  • Gleahan and the Knaves of Industry: Does Gleahan see an opportunity to confront Nathaniel's goons? You can bet he'll take it.

    Literature 
  • The Dresden Files: Most of the time Harry comes up with rather decent plans, it's just a given fact that everything will go wrong for him in some way, forcing him to do this. That does not mean it is not his first plan for each given situation. Notable moments being riding a revived Sue the Tyrannosaur directly into a group of necromancers trying to become gods, his battle plan to stop the Summer Lady from ruining the balance in Faerie, and challenging a noblewoman of the Red Court of vampires to a duel to the death to get a girl his daughter she kidnapped in the middle of her speech to the White Council apparently calling for an end to the war between the two groups.To quote from the twelfth book, Changes, "Fuck subtle." When playing in-universe RPGs, though, Dresden lives this trope. Anything else would be too much like work.
  • In the Cory Doctorow novel For the Win, one of the only American characters in the book likes to make money by working with a group of Chinese gamers that help rich westerners with tough MMO battles for a living. Their "customer" in this case plays the trope completely straight, charging recklessly into the boss chamber and ruining the team's careful plans.
  • In The Cry of the Icemark, some militia breaking ranks to pursue the enemy at the wrong moment results in the loss of an entire elite regiment.
  • Discworld:
    • In his first appearance in Guards! Guards!, Carrot Ironfoundersson is something of a Leeroy Jenkins — except he still has discipline, and can be forestalled from doing any crazy shit by ordering him to do something else. Further, because he's Carrot, he pulls off what little Leeroy Jenkins-ish stuff his fellow watchmen don't stop him from doing (arresting a dragon, arresting the head of the thieves' guild, arresting a rowdy bar in Ankh-Morpork, and arresting the Patrician). It should be pointed out that Carrot is technically the king of Anhk-Morpork which means that his success is justified. Remember: in Discworld, Reality is the bitch of the Theory of Narrative Causality.
    • In Jingo there are also the D'regs, desert tribesmen who live to wreak havoc on the Klatchian establishment. When Carrot asks one of them if it is wise to charge an enemy under particular circumstances, the D'reg replies, "it is always wise to charge." Carrot convinces them not to.
  • Namechecked in Implied Spaces: when Grax the Troll's battle cry turns out to be "Grax the Troll!!!!", the protagonist's cat remarks, "Not exactly 'Leeroy Jenkins', but I suppose it will do.".
  • The Arends in The Belgariad are a whole race to which this trope applies... they have a reputation for charging headlong into battles with little to no planning, though it crosses over somewhat with Honor Before Reason in their case.
    • Against anyone else, they're likely to win anyway just because any Arendish knight who's still alive is so because he's survived this sort of insane charge before.
  • Harry Potter
    • Harry Potter is like this all the time. It's significant character development in Deathly Hallows when he knows exactly where Voldemort is and what he's up to... and he deliberately doesn't move to stop him, despite Voldemort gaining a very powerful magical artifact as a result. It works out for Harry; the wand Voldemort gains doesn't work for him at its full power — because Harry has already become its master.
    • Sirius Black also shows this tendency in Prisoner of Azkaban. Upon learning that the traitor who framed him has been living with the family of Harry's friend for the last twelve years in a guise of a rat, he immediately springs from the prison and rushes in to save his godson. This leads said godson to think he's evil and spend the entire book working against him.
  • In Redwall, Felldoh comes over as one. His actions cast all of his friends and the army they were leading, which wasn't prepared, into a deadly battle that wasn't planned. It ends with his death. He was a berserkir squirrel. What can one expect?
  • Percy Jackson and the Olympians:
    • Oh, Percy, it's easier to count the times his plan doesn't boil down to: "I'll just make it up as I go along and try not to get killed" (especially when he's leaping to someone else's defense.) This contrasts with his best friend Annabeth who is The Strategist. The combination makes them unstoppable fighting partners /Battle Couple however as Annabeth admits.
      Interviewer: Who would you most like to have with you in battle?
      Annabeth: Oh, Percy. No contest I mean sure he can be annoying but he's brave and he's a good fighter. Normally, as long as I'm telling him what to do, he wins in a fight.
    • Of course this reflects their godly parents tactics as Percy's Dad Poseidon also slips into Leeroy Jenkins as the Chaotic Good God of the Sea, while Annabeth's mom is the Goddess of Wisdom and Battle Strategy.
  • The Seventh Tower: Don't even try to tell Milla to retreat. If she's not getting you captured by the guards, she's getting you smote off a hill by angry sentient clouds.
  • Larry Niven's Known Space: the sentient-carnivore Kzinti always attack before they're ready. The greater the chance of defeat, the greater the honor of victory! This tendency was bred into them by the Jotoki, and eugenically bred back out when their suicidal warriors died in glorious battle.
  • There are whole fleets in The Lost Fleet that fight in this way. Deconstructed as it results in heavy losses. Averted in one battle when the plan was seemingly to head-on battle with twist at the end.
  • Count Thespides from the Conan the Barbarian story "Black Colossus" ignores Conan's sage military tactics and rushes into battle with his men, falling straight into the fiery trap of Natohk in the process, mainly due to his aristocratic pride and his difficulty in taking orders from a foreign barbarian. Conan refuses to go to his aid, and when Yasmela's page asks why, he replies, "Because I am not so great a fool as he."
  • The eponymous Prince Roger, much to the constant despair of the marine attachment trying to safely get him home from the Death World they're shipwrecked on, partly due to thinking him just a Long-Haired Pretty Boy that needs saving from his own incompetence. They later discover that while Roger does charge off half-cocked at times, he's more than just the foppish dandy they've always pictured him as, as it was Roger's habit to ditch his guards when out on hunts, which left no witnesses for his badassery while hunting big game.
  • In Septimus Heap, Jenna attacks Jakey Fry without a concern for not being seen by the pirates that are fighting above her.
  • Trapped on Draconica: Ben uses the name as a battle cry. He tries to explain the Trope Namer to his companions but ultimately gives up.
  • Rand al'Thor of The Wheel of Time goes back and forth on his propensity for this depending on his current Sanity Slippage status. One notable instance is in Path of Daggers when, under the influence of an insanity-inducing Amplifier Artifact, he unleashes a lightning storm that does as much damage to his own forces as to the enemy. After gaining Enlightenment Superpowers in the later books, this strategy tends to be more successful because he's just that powerful.
  • Julian orders Libino to take half a legion and go off to negotiate with a German King. On the way, he meets a German force five times his own. He promptly orders an attack, and he and his Romans are massacred.
  • In War of the Rats, we have a squad of newbie snipers who are assigned to monitor but not fire on German soldiers during the siege of Stalingrad. One of the newbies gets fed up with seeing all these prime targets walking around and screams an order to open fire. The ensuing fusillade gives the German mortarmen a perfect opportunity to shell the crap out of them. Nice Job Breaking It, Hero! is in full effect.
  • In Warrior Cats: Sign Of The Moon, Foxleap decides to save the rogues from an eagle attack, so the Clan and Tribe cats drive the eagle off. But it results in one Tribe cat to get taken away by a hawk. Foxleap feels guilty about this, but as one Tribe cats puts it when scolding him, the damage had been done.
  • A Mage's Power: Tiza would have been this if Sathel hadn't drilled it out of her. She loves rushing into danger and sometimes forgets that she's part of a team. Thanks to her apprentice mentor, she always has some rudimentary plan and will drag at least one of her teammates by the hair into trouble.
  • The protagonist of The Knights of the Cross has taken a (spontaneous) vow to gather three evil knights' helmet plumes. So what does he do when he sees an evil knight with a plume in the middle of the good guys territory? Attack! Which is how he gets into trouble for attacking an envoy.
  • At the start of his trial to become a full member of the Guild of Mages in Spells, Swords, & Stealth, Grumph very deliberately charges straight into the arena rather than take the time to make preparations. This actually works in Grumph's favor, since charging through when most in this situation do take time to make those preparations means he also passes the enemies set to oppose him while they are still getting into position. This gets Grumph to the first major obstacle in the trial without incident and with enough time to get through it before they catch up to him. It also mitigates the fact Grumph doesn't have a lot of magic or mana to make preparations with, because he Leeroyed in a more metaphorical sense by insisting on taking the trials almost immediately to get help to his friends as soon as possible, which he could only do by getting full membership.
  • Subverted in The Hearts We Sold. The Daemon is viewed as this by the rest of his kind, since he works closely with humans (who are often viewed as being too unpredictable to be useful), breaks several rules of interacting with humans, and generally goes off and does his own thing while his superiors stick to their own, safer plan. However, it quickly becomes clear that the Daemon is the only one making any real progress towards their goal. It's worth noting that while other demons view him as being a foolhardy extremist, the human characters think of him as inhumanely pragmatic.
  • Martin, the main character of Magic 2.0, is definitely this. This becomes clear early on. Despite being a programmer and a hacker (who hasn't gotten caught hacking anything), he tends to be pretty impulse and doesn't think things through before rushing into the very thick of it. Fortunately for him, his more thoughtful friends tend to take advantage of this and use him as a distraction for the real plan. Martin's showy nature also tends to attract as much attention as possible. In the second book, he gets praise for this from a guy, who initially doesn't like him. In that guy's mind, Martin acts "like a real man" by charging in without thought for his own safety, while everyone else is still reacting. When Martin points out that he screws up a lot, the guy insists that trying and screwing up is still better than not trying at all. Note that this doesn't make Martin stupid. In fact, in that same book, he is the one who figures out the identity of the Big Bad, while everyone else is at a loss (mostly because the others are assuming other people are logical, while Martin knows for a fact that they aren't). In the third book, Martin's ability to act without thinking everything through becomes key during the climax, as his companions are an engineer, an architect, and a clothing designer - all of which require time to properly plan things out. His poorly thought-out plan and improvisations end up saving the day, especially after he tells the others not to poke holes in the plan and just do their part.
  • Fire & Blood: At the start of the Dance of the Dragons, Aegon II's initial plan for dealing with his half-sister (and legitimate heir to the throne who he was usurping) was to rush her on the heavily fortified island of Dragonstone, all on his own. His mother and uncle in-law had to patiently explain why this was a stupid idea, dragon or no dragon.

Averted as a councilor to Daenerys, where he tends to council restraint, instilling her with patience and doing things the right way, even if it is harder or longer.
    • Stannis notes that Robert had this quality. He refused his advice and marched West and suffered his only defeat at the Battle of Ashford, at the hands of Randyll Tarly.
    • Jaime charging at Drogon, armed only with a lance, in order to try and kill his enemy commander, who is being protected by a dragon.
  • In an episode of Workaholics, this is foreshadowed in the episode "Office Campout", Montez mentions how he's showed the guy's cool internet videos, like Leroy Jenkins. Then at the end of the episode, Adam subdues what he thinks are two criminals by charging them with a fire extinguisher and shouting "LLLEEEERROOOYYY JEEENNNKIIIINSS!"

  • Firefly
    • Back in his army days, Mal from had a tendency to be this. Possibly as a result, hardly any of his squad members survived.
    Zoë: First rule of battle, little one: Don't ever let them know where you are.
    (Mal bursts in firing behind her)
    Mal: WHOO-HOO! I'M RIGHT HERE! I'M RIGHT HERE! YOU WANT SOME O' ME?! YEAH YOU DO! COME ON! COME ON!
    Zoë: ... Of course, there are other schools of thought.
    Mal: They don't like it when you shoot at 'em. I worked that out myself..
    • In the movie, it's the always cool, competent Zoë of all people who does a minor version of this, abandoning the defensive line set up in order to fight the Reavers hand to hand. She's obviously being affected by Wash's death. The sheer death wish of this move horrifies even Jayne.
  • Babylon 5
    • the show features a whole species of Jenkinses in the Narns. The biggest instance is in the pivotal episode Severed Dreams, where Garibaldi declares to his team that they've reached the right spot to hold their ground against the imminent boarders. The Narns keep going; he shouts "Nuts!" and orders everyone to follow them. Described in the script as "But the Narns, being Narns, keep going."
    • The Minbari are also a milder version of this. They are said to be psychologically unable to back down or retreat from a fight that is picked with them, but they make up for it by being extremely advanced with powerful warships and shock troops, and able to design amazing battle strategies while they fight.
  • In an episode of My Name Is Earl, Randy decides to stand up for his little brother against an angry mob.
    Randy: Besides, you know I've always wanted to fight thirty people at once. LLLEEEERROOOYYY JEEENNNKIIIINSS!!
    (Dives headlong into attacking mob)
  • In Scrubs, Laverne helps Carla break in Turk's car by shouting, "LAVERNNNNE ROBERRRRRRTS!!" and punching the window. To her dismay, Carla had the keys to Turk's car in the first place.
  • Interestingly, this trope appeared in its modern form years before popularization via the internet. An episode of Matlock features Matlock's sidekick conducting a screaming charge (ultimately into a couch) with "TYYYYLER HUUUUUUUDSOOOOON!"
  • Psych has a villain named after the original Leeroy, whose name Shawn announces with the appropriate gusto.
  • Occasionally on Flashpoint, a hostage will try to take on the subject. It never ends well.
  • 24
    • Chase often got into trouble in the third season because of his tendency to act on his own, especially when pursuing Jack to Mexico.
    • Many plans that are laid out in detail that involve civilians or former terrorists fall apart when someone deviates from the plan and acts independently, like in the first season, when one of Senator Palmer's aides stabs the person she is supposed to be recording instead of excusing herself after learning of his planned rendezvous with a fellow conspiracy member.
    • This later causes another Leeroy moment when Jack Bauer poses as the murdered guy to meet the conspiracy member. As he waits in a cafe, one of the snipers who has a personal issue with Bauer begins to taunt him before being told to shut-up by CTU head George Mason. When the conspiracy member realizes Jack is not the guy he was supposed to meet, the sniper ignores all instructions to hold fire (they needed the guy alive) and fatally shoots the suspect causing a loud "DAMNIT!" from Jack Bauer.
  • Barney Stinson from How I Met Your Mother does this in an episode. BARNEEEY AH-STIIIIIN-SAAAAHNNN!!
  • Buffy the Vampire Slayer
    • Spike sometimes does this. He's perfectly capable of coming up with a good plan, but he rarely has the patience to pull it off. This tendency was made clear in his first appearance, when he was supposed to lead the vampires to kill Buffy on the Night of St. Vigeous, a day of vampiric significance when their power would be heightened — but attacked the day before instead, getting a lot of them killed because he was too impatient to wait.
    Spike: I had a plan! A good plan! Smart! Carefully laid out! But I got bored!
    • On occasion, Buffy show shades of this. But really, it's to be expected, considering that her job basically consists of two things: figuring out how to kill something, and doing so.
    • Faith too, which leads her into trouble in "Bad Girls."
  • Heroes season four has Peter rushing off to stop a madman with a gun when he has Rene's ability, in spite of Claire's insistence that he should've sent her since she's the one that can't be hurt by bullets. Partially justified in that he's trying not to think about the fact that Nathan is dead.
    • in Heroes Reborn, one of the characters can transform herself into a video game character and go into the game itself. However, she's surrounded by mooks and needs a little backup. Queue the fanboy character logging in under his own avatar and shouting this as he plows in.
  • There is the episode in Lost where the survivors corner Ethan, but just as they are going to imprison him and presumably ask him some vital questions about the island, Charlie shoots him. There is at least one review out there calling Charlie a Leeroy Jenkins.
  • Stargate Atlantis. Ronon has shades of this, preferring action to planning. However, Sheppard is usually able to restrain him and he generally goes along with the plans. Though with growing reluctance if the plan involves not killing Wraiths.
  • Pretty bizarre considering the source, but Zeke and Luther has one of these coming from Nana Waffles. Even weirder considering the context, which... involves her playing an MMO with a few other people who are carefully planning out their strategy.
  • In the season finale of Community, For a Few Paintballs More: "VICKI!!!"
  • Mulder of The X-Files is infamous for rushing into dangerous situations without thinking things through, usually with less than great results.
  • The "real" Leeroy invades CNN's 2012 virtual Super Tuesday coverage on The Daily Show.
  • Clark Kent from Smallville has an annoying habit of charging into a situation without checking the area for kryptonite or other anti-Kryptonian hazards. He also often doesn't notice he's lost his powers until it is too late.
    • In the episode "Prophecy", Clark's powers get transferred to Lois Lane. She overconfidently charges into action and Toyman quite easily defeats her with a mind-control device.
  • Level Up: The Leeroy Jenkins meme is referred to by name (as well as the follow-up line, "he just ran in"). It's a shoutout because "Conquerer of All Worlds" is an expy of "World of Warcraft."
  • Dog with a Blog: Avery does this when she and Stan attempt to get revenge on Stan's former in-game friend, Killgore. Avery, being pretty new to game, has zero patience for Stan's plan and attacks before Stan is ready They still defeat Killgore, who is still pretty savvy, but not match for the surprise attack.
  • Talyn in Farscape demonstrates that, bad as many Leeroys can be, it's even worse when it's a Living Ship that has this problem.
  • In Hercules: The Legendary Journeys, when Autolycus the King of Thieves was younger, he was very reckless and arrogant, charging straight into vaults and tombs without paying any heed to traps and guards. When Autolycus meets his younger self with time travel, he is disgusted by him and wonders how he managed to survive long enough to learn caution and planning.
  • In one episode of The Big Bang Theory, during a game of Dungeons and Dragons, Rajesh expresses disdain for caution and charges headlong into a trap in the first few minutes. His character is killed and he spends the rest of the episode hanging out with the girls.
  • Kamen Rider Stronger's Sidekick Denpa Ningen Tackle was prone to do this rather than waiting for the main hero on numerous occasions - always with predictable results.
  • Jason Landers in Aaron Stone was prone to running his avatar headlong into the fray without regard for caution or strategy in the game 'Hero Rising', resulting in him being infamous as the worst player in the game. Totally opposite to his brother who was seen as the 'best' player.
  • The Flash (2014):
    • Barry is prone to just charging into situations, believing his speed makes him infallible. He often gets tripped up by opponents who come prepared and use the environment against him. In the crossovers with Arrow, Arrow tries to teach him to mind his surroundings and not get cocky.
    • In the Episode "Rupture", Barry has lost his powers, and Cisco uses video-game controllers to drive a Flash hologram around the city. Psyching himself up to send the hologram against the episode's Big Bad, he cuts loose with a big "LEEEEEEROOOOOOYYY —" before the show cuts away to another scene.
  • Red Dwarf introduced a convict named Kill Crazy, who was obsessed with killing. When the crew accidentally end up in the Canaries, Kill Crazy, excited that he finally has a shot at some action, charges into the fray and knocks himself out before he even manages to exit the diving bell. Another episode shows that this tendency actually works against a mutated creature, causing it to flee upon seeing him.
  • Star Trek: Deep Space Nine: The season 6 episode "Sacrifice of Angels" features Sisko attempting to get Dukat's ships to start chasing his own rather than remain in their strong formation with the Dominion. Dukat sees right through it and outgambits Sisko. Later on in the episode, the Defiant single-handedly charges into the wormhole where a much larger Dominion fleet is headed to the station, though they realized that without the divine intervention that they eventually received, it would have been a Suicide Mission.
  • In The Wire: some Barksdale soldiers headed by Cutty and Slim Charles plan an ambush on a corner that Marlo Stanfield's dealers hold. To try to counter the loss of accuracy that is typical with drive-bys, the guys in the car - Country, Chipper and Bernard - are to attack once Cutty and Slim Charles strike first and have the Stanfield dealers distracted. The guys in the car, however, are far too eager for glory and decide to attack without waiting for the signal and to disregard all the tactics they had been told to use, including keeping their driver out of the line of fire. Not only that, but one of Marlo's lookouts spots them before they even try to pull it off, so the dealers are already armed and ready when their car went by. Only Bernard escapes the car alive with the targets barely scratched, while Country and Chipper are killed. Cutty and Slim Charles, meanwhile, quietly slip away in the chaos.
  • Off-screen example, but in the first season of Black Adder, Richard the IV runs into a castle filled with Turks with only a fruit knife to use. And despite all of this, he succeeds. Of course, he is played by BRIAN BLESSED.
  • In the Agents of S.H.I.E.L.D. episode "Heavy is the Head", Lance Hunter ices the rest of the team and charges in to face off with superpowered HYDRA goon Carl Creel alone. It nearly gets him killed.
  • Parks and Recreation: "The Possum" has Leslie organize a battle plan to capture the titular possum, only for Andy to run up behind her and successfully tackle it.

    Pro Wrestling 
  • Shawn Stasiak's gimmick upon his return to the WWE during The InVasion Angle basically involved him charging into a situation and knocking himself out on ringposts or whatever happened to be scattered around the area, which culminated in him charging into a suit of armour that happened to be at ringside.
  • Bobby Lashley has had at least three teammates that fit this mold. The first two were Mike Mondo and Ms. Blue while he was a part of Bolin Services, where he would end up getting in fights and matches he really wanted no part of in order to save them. Then when he was working with MVP in TNA, Kenny King was always provoking fights that they sometimes had to save him from and once nearly cost Lashley the World Heavyweight Title to Tommy Dreamer. King possibly saved Lashley from Samoa Joe the Impact prior though, so he was not completely useless.
  • Future Of Wrestling Heavyweight champion Sean Allen had an entourage of four men accompanying him, but Frank Stone was confident, because he came up with a three step plan on Caged Heat Radio's Reality Check.
    "Let me see, I'm just gonna put my foot up his ass and hopefully he'll be in space. That's number one. Two, take goldie white, put her across my shoulder and parade around the ring and say it's mine. Three, walkout of there as the new FOW champion, that's a great freaking plan."
  • ACH in Adrenalin Rush in Ring of Honor, with Ta'Darius Thomas having to rein him in. Jimmy Jacobs uses this tendency to injure him and draw Ta'Darius into Decade.

    Tabletop Games 
  • Dungeons & Dragons:
    • In 1st Edition, the Cavalier class in the Unearthed Arcana supplement is required to charge recklessly into battle, even if doing so interferes with or harms his allies.
    • The 3.5 character class Knight is encouraged to act this way. Knights cannot make surprise attacks and gain bonuses for shouting challenges at foes, so the most effective tactic is to charge into a room and bellow out a challenge. However, unlike the 1st Edition Cavalier, the Knight isn't penalized if he chooses to wait for a tactically intelligent time to do so. Such as right after his allies has sprung a surprise attack. The class is built to allow you to avoid being Lawful Stupid, an Idiot Hero, or Honor Before Reason to the point of being unable to function if you don't want to play that way.
    • In 4th Edition, there's actually an item that acts as a Leeroy: the Invulnerable Coat of Arnd, which goads its wearer into pulling increasingly bold and stupid stunts in the middle of battle and rewards him or her for doing so. The Coat goes back as far as First Edition, although artifacts in 1E didn't get fully detailed descriptions.
    • 4e also brings us the "Essentials": retools of various classes that take out various complexities and typically boil down to "Pick a stance/state, start making melee basic attacks". This was done in the interest of making "simple" characters for either new/casual players to pick up, or longtime vets who didn't feel like picking from a large array of powers every turn. What they didn't count on was the fact that the "Scout" Rangers, "Slayer" Fighters, "Hexblade" Warlocks and "Berserker" Barbarians all had either stances or abilities which greatly enhanced charge attacks; couple that with a gross number of magical weapons and armor pieces that give bonuses to charge or basic melee attacks, and suddenly a Leeroy Jenkins maneuver is the best strategy available.
    • Subverted by war gods like Greyhawk's Hieroneous and Forgotten Realms's Tempus, who explicitly discourage this. While glorious charges are certainly admirable when the situation calls for them, knights and soldiers are encouraged to fight strategically. Ambushes, pincer movements, guerilla tactics and other actions are all perfectly acceptable if they get the job done more effectively.
    • Planescape:
      • In this campaign, one of the major Factions, the Transcendent Order (or the Ciphers) has a requirement for being a member: you must always act on your first impulse. For a Player Character who joins, this gives the Player a rather unique penalty: once he has decided on an action, he is not allowed to change his mind. (In other words, this is where a "no takebacks" rule is mandatory for a player). This does not mean the Player will always become a Leeroy Jenkins, but it might increase the risk or it happening.
      • As opposed to the well-disciplined war mongers that make up the infernal armies of Hell, their chaotic counterparts the demons are like this, having no other plans but "scream and charge".
  • The GURPS team seems to love Leeroying, inasmuch as there are so many Disadvantages that can produce it:
    • Berserk: You must roll to avoid Leeroying any time you take 3 or more hits in one turn, or under "Other conditions of extreme stress (GM's option)" — i.e. pretty much in any combat.
    • Bloodlust: You must roll to avoid Leeroying any time you have a chance to kill a "legitimate enemy" — i.e. pretty much in any combat.
    • Impulsiveness: You must roll to avoid Leeroying any time the rest of the party are taking too long discussing something — i.e. pretty much before any combat.
    • On the Edge: You must roll to avoid Leeroying any time you have a chance to deliberately put yourself in mortal danger — i.e. pretty much before or during (and possibly after) any combat.
    • Overconfidence: You must roll to avoid Leeroying any time you feel yourself a match, or more than a match, for your opponent — i.e. pretty much in any combat.
  • One survival suggestion in Paranoia is to trick everyone else into playing the Leeroy.
  • Warhammer has three variations on this. The first, Frenzy, results in berserk units rushing after those expendable goblins, getting hammered in the face by Night Goblin Fanatics (who are spinning like tops and wielding massive iron flails) and then being surrounded (or, possibly, ending up in quicksand, falling over a cliff, or other unpleasant fate). The second comes when an enemy unit runs away and the troops who defeated them rush forward to catch them, disrupting a perfect defensive battleline and opening a hole for the enemy to exploit once they've finished ganging up on the Leeroy unit. The third is an inbuilt feature of some units such as Bretonnian Knights Errants to disregard any orders and impetuously charge the nearest enemy unit they can reach.
  • Warhammer 40,000 has the Universal Special Rule "Rage," which forces units with it to move at full speed toward the nearest enemy and attempt to assault it in close combat. For more detailed examples:
    • Followers of Khorne are infamous for hurtling towards the enemy, heedless of any battle plan or even their own safety, while screaming "Blood for the Blood God! Skulls for the Skull Throne!" Though Khornate units are very nasty in close combat, this predictability and recklessness can get them killed, but as the saying goes, Khorne cares not from where the blood flows, only that it flows...
      • The Black Crusade supplement The Tome of Excess features explicit rules on how to obtain Khorne's favour by doing this very thing. Given the exact description in the supplement, and that the supplement was written several years after the Trope Namer, it seems likely to be directly inspired.
    • Among the Chaos Space Marines, the World Eaters, Khorne devotees themselves, are infamous for this. During the Horus Heresy, the Archtraitor was trying to bombard a force of loyalists from orbit, only to learn that Angron had taken his legion and made an unauthorized Drop Pod assault. Horus was so incensed that he nearly continued to bombardment anyway, but he knew he'd need the World Eaters to besiege the Imperial Palace on Terra, and so sent additional forces down to support them instead.
    • The Blood Angels and their successors also fall victim to this, despite being loyalist Space Marine chapters. They're afflicted by a condition called the Red Thirst, which can cause even the most disciplined of Devastator units to ignore orders, abandon their positions and try to bludgeon the enemy to death with their heavy weapons. In extreme cases this will intensify into something called the Black Rage, in which the Astartes forgets his own identity and is lost to the Genetic Memory of his Primarch's death. Such unfortunates are grouped into the Death Company, equipped with close combat weapons, and unleashed upon the enemy - any who survive this battle are granted the Emperor's Peace afterward.
    • The Flesh Tearers are a particularly tragic successor of the Blood Angels, where they're griped by the Red Thirst and Black Rage harder than their progenitors. This has the unfortunate side effect of them succombing to the rage faster than they can recruit new marines; even with their aggressive recruitment tactics it's suspected that Gabriel Seth, the current Chapter Master of the Flesh Tearers, will be their last. Because of this, most imperial forces hesitate to ask for their help, as whether intentional or not the Flesh Tearers can't really abide by any battle tactic other than "charge forward and bash faces". Seth himself has embraced this, reasoning that if they are to die out, they can at least take the Imperium's enemies with them.
    • The Space Wolves' newest recruits are prone to this, as these Blood Claws are out to make a name for themselves and get so excited about charging into the enemy that they might forget to shoot their pistols beforehand. The ones who grow out of it are promoted to more tactically-flexible Grey Hunters, while the ones who don't are given armored motorbikes or jump packs so they'll be more effective at it.
    • The Orks have strong Leeroy tendencies because the race is so aggressive and naturally fractious that even if the Warboss has a plan in mind, there's no guarantee all the mobs under his command will follow it.
    • Ciaphas Cain (HERO OF THE IMPERIUM!!) remarks in Duty Calls that the closest thing to actual tactics that you can get Battle Sisters to follow is to point at the enemy, yell "Heretic!", and get the heck out of the way. He also believes this of the 597th's Lieutenant Jenit Sulla, who has a tendency towards reckless tactics. Played with here, however: they work nearly every time, and Amberley Vail notes that while Sulla's units tend to take slightly higher casualties than average, they also have vastly higher morale.
  • Werewolf: The Apocalypse has several "battle howls" a character could use. One of them, a signal that one was going to try something particularly daring, desperate, or deranged, was interpreted by younger werewolves as, roughly, "Hey, watch this!" and by older werewolves as "Back off, I'm gonna try something stupid!" On the bright side, if they pulled it off, they would often get a lot of Glory points.
  • Wargames Research Group:
    • The Impetuosity rule on historical wargames DBM and DBMM.
    • The 6th edition army lists describe the Feudal Japanese: It is difficult to imagine how else this army could be used except an immediate impetuous charge, but usually that is enough.
  • BattleTech. The most reckless faction in the setting is Clan Ice Hellion, their primary tactics is strike fast and hard with medium and light mechs. They decided invade the Inner Sphere to reach Terra, by fighting their way in the well garrisoned Clan Jade Falcons occupation zone. The Falcons along with the Hell's Horses retaliated against the invading clan, and only a handful of Clan Ice Hellion survived.
  • in Unicornus Knights, Princess Cornelia will attempt to head straight for the capital, and will not avoid a fight, even one she will clearly lose. The players' job is to get her there and defeat the Emperor instead of getting herself killed. Averted if you play using Cornelia's strategist personality card, in which case she is able to move tactically.

  • BIONICLE:
    • Makuta Icarax doesn't like the complex plan that Teridax has thought up to conquer the universe and thinks that everything would be easier if the Brotherhood of Makuta simply demolished everything in its path (which to be fair, they could legitimately do). He's by no means dumb and capable of coming up with good plans himself, but as fellow Makuta Krika notes, the only way Icarax's own plans would be accepted over Teridax would be if they had even better chances to succeed...and Icarax's average plan is called out as "about as subtle as an axe to the face and usually about half as interesting."
    • While Icarax's attitude has gotten him seriously hurt a few times, he at least hasn't endangered his fellow Makuta or their plans yet. Toa Vakama, however, is another story: in his determination to make a rescue, he refused to acknowledge that something was very wrong and wouldn't make time for little things like "caution". He ended up marching his team straight into the enemy base, where they got captured, mutated into half-beast freaks, and nearly killed. His team wasn't happy, and they didn't let it go until they realized their griping was helping to lead him to a Face–Heel Turn.
    • Icarax ultimately inverts the trope when he tries to throw a wrench into Teridax's plan. Teridax's supporters kill him for his effort — but when the plan succeeds, said supporters have suddenly Outlived Their Usefulness...

    Visual Novels 
  • Fate/stay night:
    • Shirou, several times. Most notable? Charging out of cover unarmed at Gilgamesh in order to save a girl. A girl who just had her eyes slashed and a lung stabbed. And he didn't know her, and she was clearly about 30 seconds from death. Oh, and Gilgamesh just killed Berserker at least thirteen and more like thirty times in terms of damage without getting scratched. Or moving.
    • Saber pulls an impressive one way back in the Fate scenario, where refusing to take the fight to the enemy will prompt her to rush off by herself. Especially irksome since this is what you actually have to do. Agreeing to go with her makes her more cautious, but gets Shirou killed by a third party. If you try and refuse, the delays involved mean said third party is not present when very similar events go down, resulting in a better outcome.
  • Wocky Kitaki in Apollo Justice: Ace Attorney claims to have been shot in an ambush, but he is soon revealed to be a Leeroy: "according to my sources... 'you ran in 15 minutes before the appointed time... by yourself.'"
  • In Reflections on the River, Zheng sometimes rushes into situations in pursuit of the jewel which might be better approached with care.
    Zheng: Come on! I'll grab some smoke bombs and we can kick down the palace door!
    Prince Shun: Hold on. [...] Aren't you in a bit of a rush?
    Zheng: Have I forgotten something?
    Prince Shun: Quite... an astonishing amount, actually.

    Web Comics 
  • Homestuck
    • Rose Lalonde shows increasing shades of this throughout the comic.
    • John does it once as the result of some meddling on the part of the trolls convincing him it's a good idea. Normally he has enough sense to avoid it.

  • Yuri from Exterminatus Now. She has no patience for complex planning (and even then, that's stretching it — she can simply not understand any plan beyond "Target that way") and tends to do whatever comes into her head, which frequently gets the gang in trouble. Kinda lampshaded when Rogue gets back. He tells everyone else that there is a reason why Yuri's codename is "Wildfire".

    • All three media have shown her run to attack an enemy much stronger than her, just because it's an enemy an it's within her eyesight. Gaea puts it best in the comic by saying that she's basically unable to see an enemy without attacking it immediately.
  • Zhang Fei and Cao Hong are the biggest Leeroys in Farce of the Three Kingdoms. Cao Hong even shouts "Leeeroy Jenkins!" when charging at one point.

    Western Animation 

  • Scrappy-Doo of Scooby-Doo. Possibly downplayed in the fact that his recklessness didn't really destroy too many plans of Mystery Inc., since their plan essentially amounted to "split up and find the monster, figure that out when we get to it".
  • Beast Wars
    • Dinobot at any given time, to the point at which he even does so vicariously through Cheetor in the episode "Equal Measures". As a result, also Cheetor.
  • Transformers
    • Bumblebee of Transformers Animated always goes head-on into any battle, even though it's been repeatedly shown that his weapons do absolutely nothing against any Decepticons.
    • His Armada counterpart, Hot Shot, also had a tendency to do that.
    • And was still at it in Cybertron. Overhaul also has elements of this.
    • In various incarnations of Transformers, this is the consistent character trait of Cliffjumper. He's always itching for a fight and always the first to leap into action — even if, as his name suggests, that leap is off a cliff. This is especially true of G1 Cliffjumper and Prime Cliffjumper. Establishing Character Moment: From the first episode of Transformers ever...
      Cliffjumper: I'm goin' too... I wanna blast Megatron right in his Turbo-Charger...
      Optimus Prime: Just find them. We'll deal with them later...
      (Hound and Cliffjumper travel to the Decepticons' Rocket Site)
      Hound: Cliffjumper, what are you doing?
      Cliffjumper: I've got Megatron dead-center in my view finder...
      Hound: Remember what Prime said: Just find them.
      Cliffjumper: (fires and misses, alerting the Decepticons that they're being watched...)
    • Air Raid's motto is "If you look first, you may not leap", and he lives by that code with all his spark.
  • Code Lyoko:
    • William has his Leeroy Jenkins moment in episode "Final Round", during his first virtualization on Lyoko. So eager for clashing with the monsters, he never listens to Aelita's repeated calls for caution or Jérémie's orders of drawing back, and ends up captured and brainwashed by the Scyphozoa.
    • Odd has his moments, too, several times. Usually lampshaded by Ulrich: "[Odd's] nuts."
  • Grossology. Ty can be considered one, and probably the worst offense was going to a garbage dump without waiting for orders. This led to his being brainwashed by Fartor, and it took a lot of effort from his sister Abby to save him from the "fart side".
  • Family Guy does a parody of the Trope Namer where Peter Joe and Cleveland are having to face guy with uzis. Cleveland asks Joe and Peter if they are familiar with Leeroy Jenkins. Peter responds saying he doesn't know what Cleveland is talking about and then comes up with a plan that involves him running in shouting then Joe running in shouting. After Joe does a number crunch, Cleveland shouts "LEEROY JENKINS".
    Peter: Cleveland, you're an idiot.
    Cleveland: This episode has a lot of internet things.
  • Star Wars: The Clone Wars, "Storm Over Ryloth": During the first attempt to break the blockade, Ahsoka, while commanding a fighter squadron, refuses to retreat when she's told, leading to the deaths of almost all of her pilots.
  • Teenage Mutant Ninja Turtles:
    • Shredder in the original Teenage Mutant Ninja Turtles was always a threat to ruin Krang's well-laid plans by letting his hatred of the Turtles overtake him:
      • In "The Big Blow Out", as Krang was on the verge of sending Earth into Dimension X, Shredder drove the Technodrome after the Turtles, falling right into their trap that sent the Technodrome into Dimension X instead.
      • "Shredder Triumphant": Shredder and Krang appear to have pulled off the perfect plan when they capture the Turtles and banish them to Dimension X. Then Shredder brings them back to Earth himself after they taunt him into believing he hadn't really beaten them unless he actually fought them.
    • The very first episode of Rise of the Teenage Mutant Ninja Turtles has April of all people do this, complete with a Shout-Out to the Trope Namer:
      April: (gets fed up with the TMNT bickering about Raph's speech) Let's do this! APRIIIIIIIIILLL O'NEEEEEIIIILLLLLLLL!!!!!!! (leaps into action to save Mayhem)
      Mikey: Oh my gosh, she just ran in!
  • Thundarr the Barbarian. Thundarr, much to Ariel's dismay.
  • Justice League
  • Young Justice
    • Superboy gives a perfect example, (except he yells rather than shouts his name) in "Performance". The team has a plan to take down Parasite... which Superboy promptly screws up by charging in screaming. Interestingly, here it's an Out-of-Character Alert and a sign that Superboy is using the shields, as Superboy had long since grown out of this.
    • Arsenal in his first real episode. Covert ops mission? He feels like spiting Luthor, so he blows up the lab.
  • The Amazing Chan and the Chan Clan: Flip and Scooter Chan are prone to this quite a bit. (Oddly enough, though, in one episode Flip himself was the one to keep Scooter from running off before they had a plan)
  • Marcia the marsupial mouse from Blinky Bill.
  • My Little Pony: Friendship Is Magic:
    • Lampshaded and Subverted in the second part of "Friendship is Magic". Twilight prepares to charge Nightmare Moon, which causes the latter to respond "You're kidding, right?". In the end, it was just a ruse to get closer to the Elements of Harmony.
    • Rainbow Dash, on a several occasions. When facing down a Hydra in "Feeling Pinkie Keen", Twilight wonders, "What would a brave pony like Rainbow Dash do?" Answer? Charge headfirst at it. In "Dragonshy", she kicks a dragon in the face. A dragon about fifty times her size, mind you.
    • In "Daring Don't" we have the following:
    Rainbow Dash: We've got to help Daring Do retrieve the ring for safekeeping before it's too late!
    Twilight Sparkle: Okay. But sounds to me like we're in way, way, way over our heads. We're going to need a carefully thought-out plan...
    Rainbow Dash: [Flies off] I'm coming, Daring Do!
    Twilight Sparkle: [Annoyed] That's not a plan!
    • And again in "Power Ponies," when the Mane 6 arrive at the villain's headquarters:
    Twilight Sparkle: All right, Power Ponies, here's the plan. Rarity, you, me, and...
    Rainbow Dash: Come on out, Mane-iac! Or the Power Ponies are comin' in!
    [thunder crash]
    Twilight Sparkle: So much for the element of surprise.
    • In "Sonic Rainboom" one of the contestants in the Best Young Flier competition was a brown male background character that energetically shouts "Let's do this!" right before flying out of the starting gate to do his routine. This scene gave the character a small memetic status in the fandom and the Fan Nickname "Leeroy Wingkins."
    • In "To Where and Back Again", the Changelings have captured and imprisoned the Mane Six and the Royal Family. The Changeling hive has a Power Nullifier that prevents non-Changeling magic from working. While Starlight, Trixie, Thorax and Discord sneak in to try to save them, Discord loses patience and charges in screaming he has to save Fluttershy at the top of his lungs. Naturally, he is caught pretty quickly.
  • In the Samurai Jack episode "The Princess and the Bounty Hunters", one of the bounty hunters was a huge, hulking guy named Boris, who actually planned to ambush Jack this way. Princess Mira, who had previously given a rather detailed explanation to the others as to why their plans were flawed, gave a pretty brief one to his.
  • South Park had a parody of World of Warcraft with the principal antagonist being a griefer named Jenkins.
  • Of the Biker Mice from Mars, Modo, Throttle, and especially Vinnie fit this trope. Yes, all three of them. Charlie's strength is that she doesn't fit this trope.
  • Sir Sadlygrove Percidal of Wakfu. If it weren't for the fact that he is part of the main cast, his complete lack of subtlety and love for impossible odds would've gotten him killed twenty times over. Although he did die once. In fact he states he wouldn't mind dying as long as it is during a great fight.
  • Motorcity: Texas is like this, although he does sometimes try to come up with plans, just not very good ones (such as inventing a shrink ray).
  • Blitz pulls this in the second episode of Road Rovers right after Hunter says they need to figure out a way to get into the enemy base ("Let the biting begin!"). He did get inside, though... after being knocked out from a distance by a gas grenade and taken prisoner by guards.
  • Phineas and Ferb essentially recreate the original viral video with Buford in the title role. See it here.
  • Static Shock may be pretty smart, but he falls into this on occasion. In one episode, the Old Superhero Soul Power, who has Shock and Awe powers like Static, contacts him and warns that his arch-enemy Professor Menace has resurfaced. Static overconfidently charges into battle before Soul Power can stop him. He gets his ass kicked and has to be bailed out by Soul Power. Annoyed, Soul Power asks if he was even paying attention: Professor Menace is his arch-enemy, so he has a lot of experience dealing with guys who can control electricity.
  • Dastardly and Muttley in Their Flying Machines: In "Zilly's a Dilly", Dick Dastardly hires a hypnotist to make Zilly brave. Unfortunately, Zilly becomes too reckless to follow plans and Dastardly decides to turn Zilly back into a coward.
  • Ewoks: Paploo does this quite often, which eventually gets him in trouble in The Three Lessons, when he's held captive and tickled repeatedly by the giant Stranglethorn plant.
  • Steven Universe
    • "Sworn to the Sword" reveals that Pearl would repeatedly leap in front of Rose Quartz to protect her during the First Gem War. This is despite the fact that Rose was a powerful Barrier Warrior with an unbreakable shield, while Pearl is a Weak, but Skilled Fragile Speedster in comparison. Basically she was a Glass Cannon trying to tank blows for the actual Tank. When Garnet mentions this to Steven, he envisions a little montage of Pearl being repeatedly poofed into Gem form by vastly stronger foes that Rose almost certainly could have handled by herself. Then the image switches Pearl and Rose with Connie and Steven. The scene cuts to Steven's horrified reaction right before the axe hits Connie — fully aware that Connie being human can't regenerate from a lethal blow — and he immediately tries to stop Pearl's training before Connie permanently falls into this mindset too.
    • In "Jailbreak", Ruby and Steven run around Peridot's hand-ship in an attempt to find Sapphire. Sapphire is singing to help them find her, but whenever she stops, Ruby screams Sapphire's name at the top of her lungs, with zero regard for the fact that Peridot and Jasper are on the ship as well, and won't take kindly to the fact that their prisoners escaped.
      Ruby: She stopped singing... SAPPHIRE!!
    • When Amethyst is looking for a rematch with Jasper, she always runs straight at her by herself, even refusing help at first.
  • Captain Planet and the Planeteers: Wheeler, equipped with the power of Fire, has been known as this on some occasions.
  • Keith from Voltron: Legendary Defender is exactly this, though not so much with the yelling. Although initially appearing to be the most level-headed, it is soon realized that the temperamental quality of his Lion (the red Lion) matches that of its Paladin very much. Keith is prone to charging into situations (that could end up making the situation much worse) without thinking it through and is more reliant on his impulse than thought. However sometimes, it works in Keith's favor.
  • El Guante Blanco, Puss in Boots' mentor from The Adventures of Puss in Boots. Once his youth and strength is restored, all he wants to do is rush into battle, even when he is clearly still outmatched.
  • Dungeons & Dragons gives us Bobby the Barbarian, who thinks nothing of attacking Tiamat head on, much to the worry and consternation of his older sister, Sheila.
  • In Superman: The Animated Series, Supergirl starts off as this. When Darkseid built a device to cause a comet to redirect from its course and crash into Earth, Supergirl smashed it. Superman just glared at her and pointed out that he could have used the device to try and put the comet back out of harm's way. So now they had to go and stop it the hard way. Later, in Justice League, Green Lantern chewed her out for being headstrong and endangering their mission, and threatened to have her kicked out of the League if she did that again. She gets better though as the series progressed.
  • Kaeloo: In an episode of the second season, Kaeloo, Stumpy, Quack Quack and Pretty are looking for a magical artifact in the tomb of an ancient Egyptian pharaoh. At one point, they go into a chamber with horizontally suspended ropes. Kaeloo says that if they touch the ropes, it might trigger a trap, so they have to move slowly and carefully. Stumpy picks up a knife and runs through the chamber, cutting them all and triggering the trap. Stumpy escapes the trap, but the other three are impaled by Annoying Arrows and get mad at him.
  • Dewey in DuckTales (2017), his defining trait is he is always eager to charge head on to danger. He gets it from his mom.
  • In Xiaolin Showdown episode "Mala Mala Jong", Master Fung sends the Chosen Ones away from the Temple with the Shen Gong Wu when Wuya is about to attack with the titular demon warrior. Raimundo decides to go back and help, and gets captured for his effort, letting Wuya track down the other heroes. This is why Raimindo wasn't promoted along the others.
    Raimundo: But I was brave!
    Master Fung: You did not obey my orders. Your brash and impulsive actions nearly led us to the brink of destruction.

    Real Life 
  • Truth in Television: in real life there were quite a few battles that the losing side could have won if some of the troops didn't attack or charge before the order was given.
    • See, for example, the Battle of Bannockburn. The English army included large numbers of archers, who could potentially have massacred the Scottish schiltrons with little difficulty. Instead, the English knights charged en masse and were slaughtered.
    • And a more extreme example of the same mistake was the Battle of Crécy, at which, according to some accounts, the French knights actually rode over their own archers, such was their eagerness to get to grips with the English. Who shot them down by the hundred. Made worse by the French King Philip of Valois, who ordered his crossbowmen forward, without their pavises (big, thick shields) that they would normally crouch behind in safety while loading their crossbows. The French king was eager to start immediately heedless of a plan. The crossbowmen got cut down like grass to a lawnmower and started to retreat, enraging the king — who ordered the knights to charge over them, and they got bogged down in all the bodies, letting the English cut them down as well.
  • Genghis Khan made Leeroy Jenkinses out of just about every army he or his generals came across, mainly due to their perfected use of the Defensive Feint Trap. On the steppes of Mongolia, it had been a common military and psychological tactic used by steppe tribes, which (until Genghis Khan united them) had constantly battled each other and thus had a lifetime of experience using and anticipating the tactic in order to keep their troops from breaking loose and running into a trap. Pit that against armies that generally either lacked the understanding of Mongolian tactics such as fake retreating (or should have, but looked down on the Mongolians as being too uncivilized to be victorious), and/or were hastily conscripted with inexperienced, many times malnourished peasants that knew little of military tactics to begin with, and who would many times just be made to Zerg Rush an enemy? The conquest of nearly one-fourth of the entire world in the half-century that followed from countless fake routs during battle - even when they were outnumbered several times over - basically speaks for itself.
  • The Battle of Nicopolis in the 15th century, also known as the Crusade of Nicopolis, where the French Knights (does anybody see a pattern here?) disobeyed orders from the crusade leader (King Sigismud of Hungary), who asked them to wait two hours until the Wallachian scouts, led by their prince Mircea the Elder, returned. The French accused Sigismund of wanting to hoard all the glory and charged. While they were successful at first, overrunning the inexperienced infantry that sultan Bayazid used as bait, they were soon attacked by archers and impaled their horses on a row of spikes that Bayazid had prepared the night before. Did the French retreat? No. They just dismounted and attacked the Janissaries on foot, beating them. Did they now have a break and rest and regroup? No. They attacked the Turkish elite Sipahi cavalry behind the Janissaries on foot, and inevitably came out second best. A lot of French high nobles died that day. Mircea the Elder knew the battle was lost when he saw the French charge and led his troops away from the field and over the Danube, to defend Wallachia from Bayzid's inevitable counter-attack once he was done slaughtering French knights.
  • Some of the least favorable interpretations of France's 19th century army doctrines, at least those established by Jomini, could probably be defined as turning the French army into a force of Leeroy Jenkins. His book's publication expenses were footed by a revolutionary general, Michel Ney, who also went down in history as this. The French call it élan. It's been suggested as one of the reasons World War I surgically removed France's then-legendary taste for war after too much élan led to one of the worst death tolls in the war.
  • Older Than Print: At the Battle of Hastings (1066) a group of Norman soldiers, fearing that their Duke, William the Bastard (so named because he was a literal bastard) had died, began to break and run. A detachment from the Saxon shield wall ran after them, and was promptly annihilated when William ripped off his helmet to show the fleeing knights he was alive, rallying them. Then the Normans decided to try a couple of fake retreats. Each time, the Saxons fell for it hook, line and sinker, whittling away their forces bit by bit. Had the Saxons wised up and held their shield wall, William may have had to back down, and the course of English history might have been radically different.note 
  • It occasionally works the other way, too. At the Battle of Missionary Ridge, the original Union plan was to stop and regroup at the base of the ridge, but the soldiers in the front line — whether due to miscommunication, disregarding the order, tactical circumstancesnote , or simply because everyone to their left and right was doing the same — simply kept going. Considering what happened to start the second phase of Missionary Ridge in the first place, it makes the fact that it ended as a Union victory even more awesome:
    (General Phil Sheridan pulls a flask from his pocket and toasts the Confederate artillery on the ridge)
    General Phil Sheridan: Here's at you!
    (the Rebels open fire on Sheridan and his staff, but only manage to shower them with dirt and make Sheridan furious)
    General Phil Sheridan: THAT WAS UNGENEROUS! I'LL TAKE YOUR GUNS FOR THAT!
    • Encouraged by Sheridan's shouting, his soldiers charge up the hill towards the Confederate guns, shouting "Chickamauga!", in the words of Ambrose Bierce, "as though the name itself were a weapon"note . This reckless advance worries the commanding Union general, Ulysses S. Grant:
    General U.S. Grant: Who ordered those men up the hill?!
    One of Grant's Aides: No one. They started up without orders. When those fellows get started, all Hell can't stop them!
  • Another highly famous incident in the American Civil War was at Gettysburg. General Dan Sickles, notorious Jerkass extraordinaire, completely ignored orders on the second day given by General Meade, and moved his entire corps forward out of a fortified position to engage the enemy. His entire corp was virtually destroyed in the ensuing battle… but he may have inadvertently saved the entire battle for the Union—General Longstreet was marching his soldiers for a coordinated attack on the Union left while Ewell attacked the Union right, and Sickles' sudden movement spooked Longstreet, causing him to counter-march via a different route under heavier cover, wasting several hours in the process and allowing Union forces to move quickly to counter both attacks.
    • This would also apply to Chamberlain's last ditch bayonet charge in defense of Little Round Top. Running low on ammunition, he ordered fixed bayonets. As the Texans were regrouping for another assault on the hill, he and his men charged into the middle of the Texans, allowing Chamberlain to hold the hill until reinforcements arrived.
  • An awful lot of the maneuvers in the American Civil War Battle of First Bull Run/First Manassas had a lot of Leeroy Jenkins moments, especially in the case of General Daniel Tyler, ordering a headlong attack by two of Keyes' regiments on the Confederates on Henry Hill without consulting General McDowell. It didn't go so well. This may have been the result of supreme overconfidence: both sides thought the war would begin and end in a matter of weeks; Lincoln's initial call for troops included only a ninety-day commitment.
  • Lieut. Col. George Armstrong Custer may or may not be an example, depending on what interpretation people have of him; in Lost Triumph by Tom Carhart, Custer was a beloved and capable leader, particularly at Gettysburg where his unit prevented the reinforcements from arriving on scene that would have turned Pickett's Charge from a colossal screw up into a gamewinning masterstroke. Custer was a major general at 26.note  After the Civil War, Custer's career moved towards more Leeroy Jenkins-type behavior, culminating in the battle of Little Big Horn.
    • Custer's attack against J.E.B. Stuart's cavalry at Gettysburg was incredibly risky, but it was well planned. Custer's brigade was greatly outnumbered by Stuart's division. But Custer also knew the field well and chose the spot to attack that did the most to nullify the advantage of numbers. Custer didn't need to take out Stuart, just prevent him from reaching the main battlefield, and to do that Custer charged headlong into the front of Stuart's column and had his horses literally collide with Stuart's. With Stuart's own front line in the way of the rest of his forces joining the fight, there was no direction available to veer away from their path to the main Gettysburg battlefield. Thus, the cavalry reinforcements that Picket was relying on never arrived, and the Union infantry (initially thrown into disarray) was able to rally back and crush Picket's outnumbered infantry.
  • The Charge of the Light Brigade was a Leeroy Jenkins moment made epic by a well-known poem by Lord Tennyson. Though it was caused more by a failure to communicate than actual impatience (some historians have suggested that the British soldiers were intoxicated), and although the actual charge was a complete disaster, it did have the lasting effect of convincing the Russians and the rest of the world that British soldiers were completely nuts, especially since their commander was under the impression that he was supposed to make a Heroic Sacrifice and saw no reason to hold back. And then the French Chasseurs d'Afrique pulled a Leeroy Jenkins themselves, broke the Russian line and covered the retreat of the Light Brigade, saving their sorry asses. Earlier that same day there was also the maneuver now known as the Thin Red Line, which basically was when the Russians tried a Leeroy Jenkins of their own and got humiliated for their trouble, by a two-men-deep line of Scotsmen, no less.
    • The same thing happened at the Battle of Minden (1759), when a misunderstood order sent a brigade of British infantry advancing on the French lines, and despite everything the French could throw at them, won the day.
      • Less well-remembered from Balaclava is the Charge of the Heavy Brigade. At a key point in the battle, the British Heavy Brigade charged uphill against a numerically superior Russian force (ordinarily a compound tactical error) and won.
      • This is one of the examples used to teach when it is OK to ignore orders, but you better have good proof to the reason you ignored orders.
  • The Swedish army in most of the 17th and 18th century battles. They always attacked, no matter what kind of a disaster it would lead them into.
    • Likewise, the Swedish Navy of the era. Ironically, it gained its greatest victory (the battle of Svensksund 1790) when it was on defensive and ambushed the Russian fleet in the notoriously diabolical Finnish archipelago.
  • The Italian Bersaglieri started out as what appeared to be a whole battalion of these: they were created by the Kingdom of Sardinia (the predecessor state of unified Italy) as light infantry specialized in charging enemy cavalry and routing it. Then Subverted when, between the excellent training in running, the good aim with what, for the time, were precision weapons (in fact bersagliere is Italian for sharpshooter), and the fact they were smart enough to charge the enemy cavalry on the side, they actually did it. And it's in the Crimean War, the same of the Charge of the Light Brigade.
  • Subverted by King Charles XII of Sweden in the Battle of Narva (1700). His 8,000 Swedes charged impetuously against 40,000 Russians and won. Tsar Peter I simply could not believe the Swedes would charge, even less seek battle against such odds. He would get used to it: the Swedish army always attacked, no matter what the odds werenote . The bookends to Narva is Poltava (1709) where 4,000 Swedes emerged from an attritive push through the Russian perimeter to face 22,000 well-rested Russians. They charged: the final great charge of the Carolean army and the end of Peter's worries.
  • Partially subverted at the Battle of Omdurman when the 21st Lancers charged what they assumed to be a few hundred dervishes, only to find they'd run into about 2,500 of them. Fully subverted in that they still won, despite being outnumbered >6-1 (of the 400 strong 21st Lancers, 70 men and 120 horses were lost).
  • Horatio Nelson, at the Battle of Copenhagen (1801), had something of a Leeroy Jenkins moment. While leading the advance squadron, several of his ships ran aground and his commanding Admiral ordered him to abandon the assault. While trying to read the signal flags, he purposely put his spyglass to his blind eye, said "I really do not see the signal," kept attacking, and won the battle (and indirectly coined the phrase "to turn a blind eye").
    • This one worked out fairly well though.
    • Admiral Parker knew Nelson would keep fighting as long as he saw a chance to win. He also knew that Nelson would make a Heroic Sacrifice unless ordered to retreat. Finally, Parker couldn't see the damn battle owing to all the gunsmoke in the air; he had no idea what was going on, and he was well aware of it. So he put up flags indicating that Nelson had permission to withdraw if he so chose—tacitly giving permission to remain as well. Nelson interpreted it correctly, and the whole "disobeying orders" thing came up later because it makes the story seem romantic. (Not that the bit with the blind eye helped matters.)
  • Gerhard von Blücher, Prussian marshal during the Napoleonic Wars (the one that saved Wellington at Waterloo), was famous for this. His nickname was Marschall Vorwärts (Marshal Forward).
  • As David Farragut is quoted (incorrectly) as saying: "Damn the torpedoes! Full speed ahead!"
  • Referenced, of all places, in this article from the Armed Forces Journal by a U.S. Army Captain who said that the phrase perfectly described U.S. attitudes towards advising Iraqi soldiers.
  • At the Battle of Ain Jalut, a Mongol army that really should have known better (since it was a favourite tactic of theirs) charged blindly after some fleeing Mameluke horsemen and were totally destroyed. Especially painful since it was the only Mongol army for about a thousand miles at the time, and had been specifically placed there to keep the Mamelukes in check.
  • During the English Civil War, King Charles I's nephew Prince Rupert of the Rhine became infamous for this. His wing of cavalry would charge, break through the Parliamentary lines - and then keep right on going, often for several miles, chasing a few scattered Roundheads. This worked well enough at Edge Hill, the first major battle of the war, but by the time of Marston Moor and Naseby the Parliamentary armies had learned to just let Rupert's men charge and chase a few of their number down — while the remainder regrouped and went back into a battle which had now lost a third of the Royalist army, including the bulk of the Royalist cavalry. This was a large part of the reason why the Royalists were crushed in those two battles, and by extension a major reason why they lost the whole war, and Charles lost his head.
  • The Battle of Adrianople, (1205) with the forces of the Fourth Crusade, led by Baldwin of Flanders and Louis of Blois, versus the Bulgarian-Vlakh-Kuman army of tsar Kaloyan, ended like this. Louis of Blois had just recovered from an illness that had left him unable to participate in the Fourth Crusade's conquest of Constantinople, and he was overeager to show his stuff. When the Kuman cavalry broke and ran, Louis charged willy-nilly after them, with Baldwin chasing Louis trying to stop him. The Kumans then encircled them. Louis died defending Baldwin, who was then captured and eventually killed in prison.
  • Also the original Battle of Adrianople in 378, when then-Emperor Valens was threatened by Fritigern's army of Goths. Valens was safely positioned in the almost-impregnable city of Constantinople, but decided this wasn't a good enough chance for a victory, so he moved his army to the much less-defensible city of Adrianople... and then moved them again to the open countryside seven hours north of the city, where he could be certain that all of the Roman Army's equipment and tactical advantage for defending a well-prepared city would be completely useless. Valens' body was never found.

    City defence wasn't the issue. The Goths were plundering the countryside and killing people. As Eastern Roman Emperor and supreme commander of the Roman army, Valens had a duty to stop them. Valens had no reason to believe that he'd lose, since the Roman army was the best trained fighting force on Earth at the time, and the Goths were pretty rag-tag in comparison. However, he lost the battle because he didn't wait for backup from the Western Emperor Gratian, who was on his way from the northwest. Had he waited until the Gothic cavalry returned from foraging (which the Roman scouts initially did not know about until the battle began) and Gratians's armies arrived, victory would have been assured as Fritigern's suprise (and improvised) cavalry charge was what had lead to the humiliating Roman defeat. He also dismissed the advice of his officers, who also urged him to wait.
  • Sgt Dan Daly was made of this trope. as seen here. At one point during World War I his Marine division was taking cover in a trench while the Germans pounded them. He leaps out of the trench shouts "Come on you sons of bitches, you want to live forever?" and charges at the Germans. The entire division shortly followed him and took the enemy position with few casualties.
  • Rear Admiral Sir Robert Arbuthnot, Royal Navy. A somewhat eccentric character, he was described by the naval historian Andrew Gordon as "in a colloquial if not a clinical sense, insane." At the Battle of Jutland on the 31st May 1916, he was in command of a small cruiser squadron covering the southern flank of the main British Fleet. At about 6pm, as the fleet was deploying into battle formation, Arbuthnot spotted a German cruiser that had been crippled by another British squadron. Instead of taking up position at the rear of the British line, he charged off after the German ship, nearly getting run over by the much larger British battlecruisers sailing up from the south. Unknown to Arbuthnot, said battlecruisers were being chased by the entire German fleet, some of whom spotted Arbuthnot's ship the HMS Defence and opened fire. Within minutes, the Defence was sunk with everyone on board, including Arbuthnot; another ship, the HMS Warrior, was badly damaged and later had to be abandoned. A third ship from Arbuthnot's squadron, the HMS Black Prince, got separated from the British fleet during the chaos, and during the night accidentally ran into the German fleet and was also sunk with the loss of everyone on board. Only one ship from Arbuthnot's squadron, the HMS Duke of Edinburgh, survived the battle.
  • Hitler had this going several ways. He picked on Czechoslovakia, which scared his generals as the Czechs had a fair shot at beating the German army in the condition it was... but got away with it because the rest of Europe abandoned the Czechs and their morale collapsed. He went to war with France and Britain about two years before his navy and army thought they were ready for it; the army wanted more time to re-equip with the Panzer III, and the navy projected a need for about 120 submarines to win the war, but only had 42, in the middle of a construction program that was scheduled to be completed in 1948. He topped it by attacking Russia before he'd knocked Britain out of the war or worked out how to actually use all that extra industrial output and manpower in occupied Europe, which might have given a him a fair shot at the Russians. He then topped that by declaring war on America just as the Russians started their first round of winter counterattacks, thereby pitting Germany against not one but two enemies it was incapable of defeating.
    • The Jablonków incident of August 25-26, 1939, foreshadowed the September invasion of Poland by one week, with Hitler temporarily postponing the Polish invasion when he learned that Poland had signed a new treaty with Britain promising to lend support if Poland was invaded. All but one of the Abwehr units, one of which was out of reach, led by Lt. Hans-Albrecht Herzner, captured a railway station in the village of Mosty, located in the then-Polish village of Mosty kolo Jabłonkowa, (now known as Mosty u Jablunkova, Czech Republic). The local Polish forces were alerted and Herzner's detachment was forced to withdraw. The Poles dismissed the incident as a blunder, with the Germans referring to this as an incident caused by one insane individual; one week later, in September 1939, the German Abwehr invaded and occupied Poland.
    • In fact, the Germans had bitten off more than they could chew even before they attacked the USA without any need tonote  As early as 1941, Fritz Todt led a committee of Germany's best industrialists, and they found that unless Germany doubled her industrial output, British and Soviet industrial power would leave her for dead. The entry of the USA into the war just sealed the deal.
    • Germany doubled her industrial output and then doubled it again, but it was already 1944.
    • And Hitler never seemed to take into account: 1) If you tick off the people of the lands you're occupying, they will take exception (most notable in the Ukraine, where the people hated the Soviets — but grew to hate the Nazis worse); and 2) the sheer amount of bodies Russia alone could throw at Germany.note 
    • Meanwhile, Mussolini was busy Leeroying up Hitler's plans. While Hitler was planning on turning on the Russians from the beginning, he really wanted to finish his business with Britain first. Then Mussolini had to go and try to rebuild the Roman Empire by invading the Balkans (with even poorer preparations than Germany had at the invasion of Poland, to boot), a move almost guaranteed to bring them into conflict with Russia. Hitler figured it would be better to attack Russia now, while nobody was prepared, rather than let Russia call up its enormous reserves of manpower.
  • During World War II, the Polish and Czechoslovak pilots who fought for Britain in the RAF were notorious for simply going into balls-out Unstoppable Rage as soon as they encountered German forces. This was a mostly positive example of Leeroying, though: the No. 303 Polish Squadron had the highest kill rate of any squadron during the Battle of Britain, and its highest scoring Ace Pilot Josef František was a Czech. František in particular was such a Leeroy that eventually his commander threw up his hands and designated him as a "guest" fighter who was basically permitted to do whatever he wanted, realizing it was of no use trying to hold him back.
  • During World War II, in the midst of the Allied bombing campaigns over Western Europe, a young American pilot by the name of Robin Olds was scouting ahead of a large formation of bombers when he came across a large gaggle of German fighters who were forming up in preperation of interecepting the bombers. Not only did he not contact the rest of his squadron to form up and hit the Germans en masse, he actually mashed his radio key to prevent his wingman from calling out a report on the sighting. He charged headlong into the mass of German fighters, followed by his wingman, and the first moment the Germans realized they were not alone in that slice of sky was when the first pilot called that he'd been hit. This worked in Olds' favor, because the Germans were still trying to form up and get organized. The sky was full of fighters, and only a small number of them were enemies. The rest were confused and panicked friendlies who were dodging around every which way trying to figure out if they were the next target of this phantom attacker.
  • The Battle Off Samar, part of the Battle of Leyte Gulf in World War II. A decoy Japanese fleet baited the bulk of Admiral Halsey's fleet away, leaving Task Force 3, a small force of escort carriers and destroyers - the early 20th century naval equivalent of Red Shirts — to face Admiral Kurita's Center Force, a large formation of battleships and cruisers that outmassed and outgunned the American force by a truly staggering margin.note  The American destroyers attacked the larger force in order to allow the escort carriers a chance to escape, and so ferocious was the American attack, that Admiral Kurita came to the (wrong) conclusion that Admiral Halsey had not taken the bait, and would soon arrive to engage them. Indeed, in the poor visibility that day the American ships' distance (and thus also size) was consistently misinterpreted, and Kurita believed that the tiny escort carriers and destroyers were Halsey's main force of fleet carriers and battleships. The Center Force retreated, resulting in one of the most unexpected victories in the history of naval warfare.
    • Of particular note is Captain Earnest Evans and his destroyer USS Johnston. Taffy 3 was attempting to retreat as quickly as possible with the escorting destroyers laying smoke to allow the carriers a chance to try and escape. Evans without orders turned his ship hard around and at full flank speed charged the attacking Japanese fleet alone. Not only did he close to within torpedo range he managed to take out of the battle two Heavy Cruisers right from the start. It was due to Evan's audacity that the rest of the force also made their own attack runs. To make his bravery even more awesome is that when a squadron of Japanese destroyers lead by a cruiser bored in to make a torpedo attack on the retreating Escort Carriers, Evans charged with his heavily damaged destroyer attacking the ships. His attack spoiled their torpedo run once again saving the carriers from attack. This did cost the Johnston as those ships ravaged her sinking the ship. While Evans abandoned ship with his crew he was never seen again. He was awarded the Medal of Honor.
    • Halsey himself provided an example of the bad form of Leeroy, ignoring the strategic mission in an attempt at tactical victory. The overall battle objective was to land US ground forces on Leyte, with the Navy providing cover against an anticipated IJN counterattack. Instead of waiting for the enemy to come to him (where he would have the help of those very escort carriers providing air cover), he rushed off to try and find the enemy in the open sea (he did, sinking some now-worthless Japanese carriers, which had been sacrificed as decoys precisely because they had no planes available to fly from them), abandoning the landing beaches and supply fleet. More than one historian has guessed that Halsey was attempting to one-up his Blue Oni and rival Raymond Spruance, who had been criticized for letting the Japanese carriers escape at the Battle of the Philippines Sea. Had Taffy 3 not made its incredibly ballsy stand, the Japanese heavies would have sailed right up to the landing beaches, sunk the transports, and then shelled the ground forces with near impunity until Halsey finally turned around and came back to chase them away. Aptly summarized by the commander of Taffy 3, Admiral Sprague:
    "That son-of-a-bitch Halsey has left us bare-assed!"
  • Also inverted in World War II; isolationists saw America as this. When it became obvious that the Axis Powers would attack America anyway because, ahem, the Axis Powers attacked America, nobody listened to isolationists for over two decades.note 
  • JNA at Vukovar. Sending tanks into a city with no infantry support? If it isn't stupid, I don't know what is...
  • Torpedo Squadron 8 at The Battle of Midway in WWII. Attacking alone without fighter cover the entire 15 plane squadron was shot down without scoring a single torpedo hit. ENS George Gay was the only member of Torpedo 8 to survive the attack. Fortunately for the U.S. Navy while the Japanese CAP was chewing up the torpedo bombers, the American dive bombers showed up and were able to attack unopposed, sinking 3 of the 4 Japanese carriers present. Fortunate timing and blind luck turned what should have been a crushing defeat into what is probably the greatest victory in the history of the U.S. Navy.
  • Hell, terrorism in general: You'll get captured or killed, and more than likely you'll turn more people against your cause than toward it.
  • Off the battlefield, the 1993 Thanksgiving Day Football Game between the Miami Dolphins and the Dallas Cowboys. The Cowboys, leading 14-13 with seconds remaining, managed to block a game-winning field goal attempt from the Miami Dolphins. All Dallas had to do seal the win is let the ball roll dead. Miami was barred by rule from touching the ball again unless it was touched first by Dallas... which is exactly what happened when Defensive End Leon Lett charged in - past several teammates trying to wave him off and screaming the code word to not touch the ball - and tried to recover the ball. He slipped on the snowy surface and ended up booting the ball forward, where Miami recovered and subsequently re-kicked for the win.
    • "Leon was not one of our main special teams players. I’m not even sure he ever worked with special teams previously, so he hadn’t gone through all the rules and regulations like somebody who was on all the special team units. We threw him into the mix because of the snow, thinking that with his size and power, he might be able to block one up the middle. It wasn’t Leon’s fault. We didn’t have him thoroughly prepared for the situation." - Cowboys head coach Jimmy Johnson
  • If you've ever been on a sports team in your school days, you can remember at least one teammate (possibly you) who lacked the good sense to stick to the game plan, was a showboat, and/or did something monumentally stupid that cost your side a victory.
  • The Japanese Formula 1 race driver Kamui Kobayashi is referred to pull - in the words of a Sky Sport commentator - "Leeroy Jenkins moments", having a tendency of doing sink-or-swim overtaking maneuvers during his F1 careers. Kamui Kobayashi has been called Kamikaze, Cowboyashi, Kobabashi and Kowasabi.
  • In the realm of business, Leeroy may be a positive role model. Peter Drucker, among others, recommends a "Ready, Fire, Aim" mentality, suggesting that barging forward and firing at a lot of targets can yield better (and will certainly yield quicker) results than involving a bunch of people in planning sessions to select a few targets. "Move fast and break things" is a motto of Silicon Valley start-up culture. Unfortunately, this doesn't always work, with startups hemorraging capital while trying to steal market share from each-other by cutting costs so low there is no chance at a profit, or just starting up unrealistic business plans with little chance of success. The Dot-com Crash was the natural result of this, with overhyped companies collapsing and causing trillions of dollars in stock value to evaporate in mere months.
  • Among EMTs, Firefighters and other emergency medical personnel, police officers are notorious for running into scenes that may have hazardous materials before the scene is properly secured while neglecting to don protective equipment, and as a result often keel over after stepping inside and have to be transported to the hospital along with the people they were supposed to save. For this reason many refer to them as "Blue Canaries" and the preferred solution is to drag the usually-unconscious cops back to the staging area (if possible to do so without creating more casualties) and wait for HAZMAT to show up.
    • Obviously, those who survive because a "Blue Canary" rushed in and showed that it was safe for other emergency responders to help save them appreciate their mindset.
  • Part of the reason bank robbers like John Dillinger were able to evade capture for as long as they did were the ineptness of authorities when it came to launching raids to capture them. The FBI's attempt to capture Dillinger and his gang at Little Bohemia Lodge in Wisconsin being a notable blunder. They accidentally opened fire on and killed an innocent civilian, alerting the gang to their presence. Due to the FBI's lack of scoping out the place beforehand, Dillinger, Homer Van Meter, John Hamilton, and Tommy Carroll were able to escape via an unguarded route that hadn't been secured, while Baby Face Nelson killed another agent at the house of a nearby switchboard operator and stole the agent's car.


"Leeroy, you are just stupid as hell."
Hey! At least I have chicken!

The Battle of Crecy (Il était une fois... l'homme)

True to the real-life example, this cartoon shows how the French knights of 1346 charged ahead before their own foot soldiers were even half as ready as they. The result is tragic.

How well does it match the trope?
