[[caption-width-right:330:And he's a One Man ''[[CaptainPatriotic U.S. Army]]''.]]

->'''Loki:''' I have an army.\\
'''Tony Stark:''' We have a Hulk.
-->-- ''Film/{{The Avengers|2012}}''

Sometimes TheHero (or TheBigGuy in his {{team}}) will face a large horde of Mooks and tell their [[BigBad leader]] he's going down. The leader will often say, "YouAndWhatArmy", then discover that the hero doesn't ''need'' one. This one man can go around and kill ''thousands'' of enemies.

The One Man Army does far more than pull his own weight. Villains tend to underestimate this person at first, considering him JustOneMan. They are quickly proven wrong. This is often [[JustifiedTrope justified]] by making the character a SuperSoldier against mundanes, possessing far superior weaponry, or otherwise tremendously advantaged.

[[ThereAreNoTherapists The damage to the psychological state]] of someone like this is not always considered. It ''certainly'' would be affected by [[ItGetsEasier taking so many lives]] away. The impact of this is lessened if the character is explictly a LivingWeapon and/or if the enemies are FacelessGoons or [[WhatMeasureIsANonHuman don't register as human beings]] and therefore exist solely to provide a MookHorrorShow.

In a series aimed at younger audiences, they may [[NonLethalKO simply defeat]] large masses of people rather than outright kill them. In playing this trope, it is useful to have TheEvilArmy try to ZergRush said character in TheWarSequence. This trope caters to everyone's inner {{Munchkin}}; 99% of {{First Person Shooter}}s ever made fall under this.

Often goes hand-in-hand with ItsUpToYou and WalkingArmory. When the One Man Army is intentionally sent out to take care of the problem by himself, it's a case of OneRiotOneRanger. Compare and contrast PersonOfMassDestruction, who's symbolically treated like a weapon by the setting, and OmnicidalManiac, who is all too willing to push him- or herself into this territory. In the latter case, the OmnicidalManiac often gains his/her/its kill-count through using [[WeaponOfMassDestruction WMDs]] on hapless civilians rather than personally fighting enemy combatants. Villains who are like this aren't bothered by MookDepletion.

Being one of these qualifies you as a CrewOfOne (though not for a BigBadassBattleSequence). However, [[DudeWheresMyRespect very few people will respect your ability]], or worse, seek to abuse it because "WeDoTheImpossible" is in effect. Contrast with the BadassArmy where each individual could be considered this but are part of said army, as well as the EasilyConqueredWorld where it's the severely, severely outnumbered enemies who are kicking ass and taking names. If one man ''makes'' the army, then you have TheMinionMaster. Likewise, if one man ''becomes'' the army, it's MesACrowd.

Compare ShowyInvincibleHero and TheAce. See also ConservationOfNinjitsu, which postulates that being outnumbered ''is'' what gives the character the advantage. A subtrope of QualityOverQuantity.

While RealLife examples do exist, this is generally not a good idea in RealLife.

[[folder: Manhua ]]

* Multiple characters in ''Manhua/RavagesOfTime'' are able to hold their own against whole armies, such as Liaoyuan Huo and Zhang Liao. A special notice goes to Lu Bu who, with his daughter strapped to his back, tried to break through the siege of Xiapi; he was severely out-numbered but managed to take out all of Cao Cao's generals and was only defeated when he was absolutely exhausted.
* Several characters in ''Webcomic/GodOfHighSchool'' are this, but very few can match Jin Mo Ri's feat of [[spoiler:wiping out over 180,000 angels the size of skyscrapers in ''under thirty seconds'' after unlocking his power as the Monkey King.]]


[[folder: Pinball ]]

* The player character "Hitman" is this in ''[[Pinball/F14Tomcat F-14 Tomcat]]'', being a lone fighter pilot against General Yagov and his Russian fighter squadron.
* The ''Pinball/AirborneAvenger'' is implied to be one.
* ''Pinball/{{Raven}}'' is supposed to be one, as a DistaffCounterpart to Franchise/{{Rambo}}.


[[folder: Theatre ]]

* ''Theatre/CyranoDeBergerac'': Between Act I and Act II, Cyrano stands against one hundred men and kills [[ButForMeItWasTuesday eight of them]] (as you can see in RealLife, this was TruthInTelevision). Between Act IV and Act V, he manages to survive the LastStand of only one company of [[ProudWarriorRaceGuy Gascon]] cadets against ''all'' the Spanish Army.


[[folder: Toys ]]

* Played oh-so-straight when Wrestling/SgtSlaughter joined the ranks of Franchise/GIJoe. [[http://www.youtube.com/watch?v=9QN1MP-QFcg The]] [[http://www.youtube.com/watch?v=EUbgVzMboKs&feature=related commercials]] were something else...
* In Toys/{{Bionicle}}, Toa usually work in teams, but there are occasions where they manage to demolish small armies. One particular example that stands out is Kopaka defeating three dozen Zyglak offscreen. What makes this even more impressive is that Zyglak are almost immune to [[ElementalPowers Elemental Powers]] which Toa usually use as their primary attack.
* [[Franchise/MastersOfTheUniverse He-Man]], the Most Powerful Man in the Universe. Of course, he doesn't always fight the forces of evil by himself...


[[folder: Visual Novels ]]

* ''VisualNovel/MajiDeWatashiNiKoiShinasai'' has [[WorldOfBadass many characters]] who can beat up masses of people by themselves. For instance, most of the named characters in the Kawakami War are essentially {{Hero Unit}}s.


[[folder: Web Animation ]]

* Hank from ''WebAnimation/MadnessCombat'' is perhaps the universal embodiment of this trope. In the flashes, he could kill ''a hundred guys in five minutes''.
** Jebus also qualifies. As well as all of the fan-characters.
* ''Website/CollegeHumor'' video "Video Game Boss Lament" has villains expressing shock to their minions at how a protagonist is able to get through them.
* ''Every. Single. Freelancer. Ever.'' from ''Machinima/RedVsBlue''. Season 9 makes this ''very'' apparent.
** When sufficiently angered, Caboose can smash his way through dozens of soldiers. Problem is, he's [[TheDitz Caboose]], so he forgets how to get angry fairly often.
* In Episode 67 of ''WebAnimation/TheMostPopularGirlsInSchool'', Brittnay [[spoiler: kills all four of ''Film/TheExpendables'', in self-defense.]]
* ''WebAnimation/{{RWBY}}'': In the "Red" Trailer, Ruby Rose carves through a huge horde of [[OurDemonsAreDifferent demonic]] [[OurWerewolvesAreDifferent werewolves]] [[CurbStompBattle without taking a single hit]]. In Volume 3, [[spoiler:Neopolitan infiltrates an Atlesian airship and slaughters all the soldiers on board, freeing Roman Torchwick and allowing him to hijack the ship.]]
* ''WebAnimation/{{Dreamscape}}'': Implied with Melinda, considering it took the ''entire population of her MirrorUniverse'' to weaken her enough to seal her away, as seen in the flashback in "The Mystery of Melinda".


[[folder: Web Original ]]

* Los Hermanos, a member of the [[Roleplay/GlobalGuardiansPBEMUniverse Global Guardians]], is literally this. He's a super-powered duplicator who can make thousands upon thousands of copies of himself.
* The [[BadassArmy Kriegan Army]] from ''Literature/{{Lambda}}''. Each soldier is trained to take down dozens of enemies by themselves. Higher up, their elite Knights of Grabacr are up there at PersonOfMassDestruction.
* In the pilot of ''WebVideo/HoganVsFlair'', the card features the "Wrestling/KevinNash Burial Gauntlet Match". It's pretty much Nash just destroying one guy after another after another with his [[FinishingMove Jackknife Powerbomb]], parodying the way the RealLife Nash would always insist on winning (and get his way most of the time.)
* [[Wiki/SCPFoundation SCP]]-[[http://scp-wiki.wikidot.com/scp-076 076-2]]
* ''Literature/{{Worm}}'' has quite a few, but the standout example is Contessa, who has singlehandedly delivered a CurbStompBattle to a large group of people in every fight she's been in.
* As a result of the Mob's total inability to switch out Pokemon, some Mons in [[TwitchPlaysPokemon Twitch Plays Pokemon]] tend to fall into this category. Pidgeot ("Bird Jesus") from the first run is the primary example, but Feraligatr ("LazorGator") and Azumarill ("M4 Moe") also have this status.
