* {{OMAC}}, from ''Franchise/TheDCU'', whose name is an acronym for "One Man Army Corps"; also a ShoutOut to a WWII medal of Honor winner who got the nickname "One Man Army Klein". Note that this is out of necessity; in a future where every country is nuclear and international tensions constantly threaten to boil over, where the risk of war is both ever-present and too great to comprehend, ''one man'' must stop conflict before it grows. Troops take too long to assemble and deploy, and a large scale conflict is not an option [[CatchPhrase in the world that's coming.]]
** In OMAC's first appearance, practically his first line is "Evacuate this section [of the building]! I'm going to destroy it!"
** [[InfiniteCrisis The OMAC Project]] is an aversion of this, as the word OMAC was originally thought to be an acronym for One Man Army Corps, but it turned out the creators took FunWithAcronyms UpToEleven by naming the [[KillerRobot individual OMAC units]] (who were an InternalHomage to the original OMAC character) "Observational Metahuman Activity Constructs", and the [[BigBrotherIsWatching satellite system that controlled it all]] was named the "Omni Mind And Community"
* ''Comicbook/ThePunisher''. Most Marvel characters already consider him not right in the head. Just look at the arc in the grittier [[Comicbook/ThePunisherMAX MAX series]] where he responded to [[spoiler:his family's grave being defiled by killing 68 organized crime members in one night]]. Also, he is shown to end up in a pretty bad shape after many of his self-assigned missions. It's implied he has to recover several weeks at time after the ones in which he's most injured. The new movies have him end in a pretty bad shape after each assailant sent against him, and in the final showdown in ''Warzone'' he responds believably to the shots that, thanks to his BulletproofVest, don't manage to ''penetrate''. For more about the movies, see below.
** In the MAX series, one police officer mentions that Castle's body count exceeds 2000 confirmed kills.
* {{Franchise/Batman}}. Whether it's dozens of FacelessGoons or merely half the Legion of Doom, you can bet that he'll get through them (without killing them, of course; this is Batman). This can often be drawn up to him being CrazyPrepared (you can totally see Bruce just sitting around going like "Okay, if a PresidentEvil took over and I was surrounded by the Green Berets, how'd I get through them all?"), but he can [[IndyPloy do it on the fly, too]].
* Likewise, {{Franchise/Superman}} for [[NighInvulnerable obvious reasons]].
* Both Rogue and Friday in ''RogueTrooper''. To make it more impressive, each comes from an army of [[SuperSoldier similarly enhanced soldiers]].
* [[{{Preacher}} The Saint of Killers]]. He ''is'' Heaven's army. Heaven's ''entire'' army.
** At the end of the series, anyway. ("You killed the heavenly armies!" "They were in the way.")
* ''ComicBook/TheTransformersIDW'' has Sixshot in the earlier comics for the Decepticons. Sixshot is ''such'' a One Bot Army, his specialty is wiping out ENTIRE PLANETS. Other notable examples from the IDW G1 continuity are [[ComicBook/TransformersLastStandoftheWreckers Overlord]], who takes on the [[BadassCrew Wreckers]] and came so ''very'' close to beating them, and Thunderwing, who became so powerful thanks to Pretender technology it took the combined efforts of BOTH the Autobots and Decepticons to bring him down [[spoiler:and he didn't even stay dead.]]. And, of course, [[BigBad Megatron]].
** Then there's [[BiggerBad Galvatron]], main antagonist of the Marvel UK storyline and [[ConquerorFromTheFuture Megatron from another time]], who regularly takes on entire squadrons of Decepticons and Autobots, and usually emerges unscathed (his foes less so). He has singlehandedly tore apart elite squads like the Wreckers and the Dinobots and in his last battle, the combined of Autobots and Decepticons from the past and future are unable to truly stop him, and only a rift in space and time ends him.
** On the autobot's side, there is Optimus Prime, obviously. Omega Supreme, Fortress Maximus and Ultra Magnus also follow this trope.
*** Nearly every 'leader' Transformers fits this trope to varying degrees.
** Grimlock and the Dinobots are basically this turned into a BadassCrew.
** Each of the Phase-Sixers (Sixshot, Overlord, Black Shadow [[spoiler:and Tarn of the Decepticon Justice Division]]) was upgraded by Megatron to be even stronger than him. Phase Sixer refers to "Phase Six" of Megatron's plans: namely, ''wiping out the populations of entire worlds''. Something each of the Phase-Sixers is able to do single-handedly.
* ComicBook/CaptainAmerica (see trope image): No other hero has been the subject of more angry commanders shouting "Kill him, you fools! He's only one man!" Although he wasn't MEANT to be a OneManArmy, just the first of many. Then stuff happened and the secret of the process was lost, leading to any number of character origins that relate to attempts to replicate it.
* John Doe, of ''NthManTheUltimateNinja'', who is ExactlyWhatItSaysOnTheTin.
* Wallace and Marv from SinCity took on several armed {{Mooks}} on more than one occasion. In fact, Wallace was flat-out called a one man army by the BigBad.
* In ''ComicBook/LastManStanding'', his character bio uses these exact words to describe [[{{Badass}} Gabriel]].
* Conquest from ''ComicBook/{{Invincible}}''. He claims he has conquered ''entire worlds'' with his bare hands. In fact, this is the standard Viltrumite strategy. They send a single person to each world targeted by their empire. Very rarely is this insufficient to take over the world in question. The [[spoiler:former]] Regent Thragg makes Conquest look like a pushover, having been trained from birth to be the strongest Viltrumite alive.
* Obelix in ''ComicBook/{{Asterix}}'' is a prime example of this, on more than one occasion taking on entire Roman armies single-handed, for fun. Any of the Gauls are capable of this when tanked up on magic potion, though.
* GrooTheWanderer would be one of these, if it weren't for his stupidity. He has an unfortunate tendency to forget which side he's on in the middle of a battle--to the point where he has found himself the only living person left on the field, having single-handedly most of both armies involved.
* {{Wolverine}} has literally fought hundreds of mooks at once. A comprehensive documentation of his combat history would include the phrase "piles of ninjas" more than once. Per page.
** His daughter[=/=]OppositeSexClone ComicBook/{{X-23}} is no slouch either. She single-handedly destroyed the ''entire'' Facility installation where she was bred (ok, her mother Sarah may have capped a couple mooks during her own escape), and has been seen carving up security personnel and soldiers by the dozens. And oh yeah, add extensive assassination, espionage, and spec ops training to her qualifications.
