[[caption-width-right:300:Can't [[Comicbook/IncredibleHulk we]] [[TheMightyThor all]] just get along?]]
-->''As intelligent men facing lunatic times, we were very alike, despising each other instantly. Recognizing me, he attacked anyway, "Mistaking me for a criminal."''
--->--Ozymandias, ''ComicBook/{{Watchmen}}''

Bob and Alice are heroes. Bonafide heroes. They beat the bad guys, they save the world, they help old ladies across the street, the whole nine yards.

They also hate each other's guts, perhaps even worse than they do their enemies.

Headbutting Heroes refers to when two heroes thoroughly hate each other, or when one hero hates another hero (it doesn't have to be mutual). This is not the same as the animosity that can form between, say, a [[TheLancer Lancer]] and his superior, since, while they may have animosity against each other, the Lancer deep down respects the [[TheHero Hero]] and will defer to his leadership. It's also different from LetsYouAndHimFight, since the heroes have not been misled to face each other. They really want to duke it out every time they meet, or at the very least they are obviously disagreeable and might try to discredit each other in front of other heroes. They just cannot get along, no matter how others might try to get them to keep it civil.

There need not be actual violence involved in the feud, though. As said before, they might try to discredit each other, or have verbal spats. If there is a threat, they will face that threat, but this will [[StatusQuoIsGod practically never lead to them getting along]]. In fact, their animosity might even become a hindrance to the situation at hand, and they might [[WhatTheHellHero get called on it by other heroes sick and tired of their bickering.]]

The reasons for such animosity are various, but they are rarely very deep. Truly worthwhile reasons for disagreement are also usually reasons they could mediate if they actually sat down and talked it out. However, part of what makes this trope is that the two heroes, deep down, don't NEED an excuse to fight. They just hate each other, and while they might have such a thing as a GOOD reason to fight, it's pretty much secondary to the hatred that has formed between them. Their reasons for disagreement could disappear, [[CharacterDevelopment they could both grow more mature and understanding]], and they'd [[StatusQuoIsGod STILL hate each other.]]

Examples of reasons for these characters hatred for each other might include:
* '''{{Rac|eTropes}}ism''': While this may seem like a reason that makes either or both of the heroes [[AntiHero seem VERY non-heroic]], it might also be a reason so ingrained in them from their upbringing that it's actually kind of tragic. For example, a Kree hero and a Skrull hero might be two guys who are admired and respected by the hero community at large, but they will NEVER get along because their cultures practically revolve around hating the other one's race.
* '''[[{{Foil}} Personality Clash]]''': The heroes don't like each other because their personalities or philosophies just clash too harshly. Perhaps a MartialPacifist is disgusted by an AntiHero's more bloodthirsty approach. Perhaps a LawfulGood / LawfulNeutral character is driven nuts by a ChaoticGood / ChaoticNeutral's more, um, [[DepartmentOfRedundancyDepartment chaotic]] approach. Perhaps TheStoic is irritated by the BoisterousBruiser's tendency to boast.
* '''[[NeverLiveItDown Never Living It Down]]''': One of the heroes did something in the past or failed in some way that has tainted them in the eyes of others, but while most heroes give him the benefit of the doubt or believe the hero has proven his worth, the rival just won't let it go.
* '''{{Pride}}''': The heroes see each other as a rival to be bested, and any action by the other hero is seen as a challenge or insult. Definitely the most petty reason AND the most permanent one. With any other reason, it might be marginally justifiable for there to be a rivalry between the heroes.

Quite obviously, {{Anti Hero}}es are VERY prone to this type of relationship with certain other types of heroes. It's almost a prerequisite of being an anti-hero that a LawfulGood hero will hate your guts. {{Sociopathic hero}}es are also prone to this, for obvious reasons.

Subtrope of DividedWeFall that involves individuals rather than [[WeAREStrugglingTogether factions]]. Compare to TeethClenchedTeamwork, where, while hating each other, the heroes are willing to set aside their difference for the sake of doing what's right. FightingTheLancer is when the teammates ''can't'' set aside their differences, and comes to blows. Compare DuelingMessiahs where it's both heroes who are like this with each other due to their conflicting methods in protecting the world. See also NoSympathyBetweenMooks for the villainous version. Also contrast VillainousFriendship where two villains are the best of friends.

[[folder: Anime and Manga ]]

* In crossovers, ''Anime/GreatMazinger''[='=]s Tetsuya Tsurugi and ''Manga/GetterRobo''[='=]s Ryoma Nagare are often going at each other's throats.
* [[DeadpanSnarker Kaede]] [[TheStoic Rukawa]] and [[BoisterousBruiser Hanamichi]] [[LargeHam Sakuragi]] from ''SlamDunk''.
* Probably ''Anime/UnGo'''s Shinjuro Yuki and Kaishou Rinroku qualify as this, although we don't actually know how much Kaishou hates Sinjuro, and they both act civilized about this and usually even cooperate. Clashing ideologies are at fault in this case.
* Kazuma and Ryuho of ''{{Scryed}}'' may have common goals at times, but once they're taken care of, it's back to fighting each other. Their ideologies and personalities, and their stubborn pride, make for unresolvable differences. [[spoiler:The very last episode is a knock-down, drag-out fight between the two of them, with no hint of friendship apparent between the two.]]
* In the ''Manga/{{Mai-Hime}}'' manga, Nao doesn't get along well with any of the other Himes, especially not Natsuki and Haruka. Unlike in the anime, however, she never turns completely hostile against the others after joining them.
* In ''Manga/OnePiece'', the Water 7 arc involves Usopp battling with Luffy with their ship on the line.

[[folder: Comic Books ]]

* Franchise/{{Batman}} has a tendency to rub many other heroes the wrong way, with some of them actually going hostile on him. Franchise/{{Superman}} is not one of them (which can surprise people, considering how opposite they are portrayed usually), but [[GreenLantern Hal Jordan and especially Guy Gardner are]]. Harvey Bullock is sometimes portrayed this way towards him too, but he eventually gets better.
** The way Frank Miller, and then John Byrne, conceived the Batman/Superman relationship played this trope straight, with Frank Miller noting that their ideologies are completely different and concluding that 'These two people do NOT like each other'.
* And speaking of [[GreenLantern Guy Gardner]], he REALLY has an ability to rub people wrong. Countless people have manifested the desire to beat the shit out of him. [[http://media.comicvine.com/uploads/0/2355/621728-int_jli_punch_super.jpg Batman actually did...WITH ONE PUNCH!!!]]
* [[IncredibleHulk The Hulk]] REALLY has this in spades. He has loads of characters he'll never get along with. Amongst them, [[TheMightyThor Thor]] is the one with whom he has the biggest rivalry. [[ComicBook/{{X-Men}} The Juggernaut]], {{Wolverine}} and [[ComicBook/FantasticFour Ben Grimm]] are also common rivals.
** As far as the Hulk goes, he and Thor will occasionally get along perfectly well until one sets the other off, and a fight breaks out. Hulk and Ben also have mutual respect for each other. That being said, the Hulk does have a few heroes he absolutely hates, especially after the PlanetHulk / WorldWarHulk incidents. Reed Richards, Tony Stark, and Professor X being among them. Wolverine and Juggernaut, on the other hand, are purely antagonistic with the Hulk.
* {{Wolverine}} can't go a week without running into a hero who wants to beat him up. If said hero is a government agent or came from the Weapon X program, even more so.
* ThePunisher is a surprisingly dark anti-hero. He kills frequently in ways which are BloodyHilarious, simply brutal, or just {{Gorn}}. Additionally, he readily goes all-out with firearms. As the name implies, mercy is ''not'' one of his virtues at all. This doesn't help his popularity with more idealistic heroes. Since he was first introduced as an adversary of SpiderMan, it's not surprising that Webhead isn't a fan.
** The same thing goes for [[{{ComicBook/Daredevil}} Daredevil.]]
* [[{{Main/Deadpool}} Deadpool]], due to his frequent work as a mercenary and assassin. Also, because everybody finds him freaking annoying.
* Namor the SubMariner has this with the MarvelUniverse.
** Primarily due to him being a [[IncrediblyLamePun royal]] JerkAss.
* [[ComicBook/{{Watchmen}} Rorschach]] is considered a lunatic and subversive by the authorities, and most heroes don't want anything to do with him. Laurie Juspeczyk, specifically, can't stand him at all.
* MsMarvel carried a grudge against [[ComicBook/{{X-Men}} Rogue]] for quite a while for [[MindRape Mind Raping]] her to steal her powers back when Rogue was still a villain working for Mystique. They eventually reconciled (but whether any given writer [[DependingOnTheWriter remembers]] that is up for grabs).
* ''ComicBook/PowerAndGlory'' has A-Pex (Allen Powell) and Michael Gorsky, his partner and handler. Even though Powell has a crippling fear of disease that leaves him relying on Gorsky to take care of things, the two completely despite each other and never miss an opportunity to cut each other down.

[[/folder]]

[[folder: Fan Fiction ]]

* FanFic/DungeonKeeperAmi features this with a very interesting twist. Sailor Mercury is a unquestionably heroic character displaced by interdimensional weirdness, and, through no fault of her own, has been made a Keeper. Keepers usually have a dash of TheUnfettered thrown in. The worst count as {{OmnicidalManiac}}s. Mercury is nothing like this. The Light's forces, however, are extreamely reluctant to consider her as anything but a madwoman to be eliminated. [[BigGood The Avatar]] outright states that he has difficulty tolerateing her on an emotional level, due to the crimes perpetrated against his people by Keepers, and he's one of the more open-minded of the Lightworld rulers.

[[/folder]]

[[folder: Film - Live Action ]]

* Happens in Film/TheAvengers, and many have argued that this is part of the movie's appeal: successfully translating the complex dynamics of the heroes' relationships in the comic books to the big screen. It is a very large plot point actually.

[[/folder]]

[[folder: Literature ]]

* This sums up Tal and Millas relationship from book 1-4 of ''Literature/TheSeventhTower'' pretty nicely, and in five, there is a certain frostiness to their relationship. Most of it comes from Millas pig-headed aggression towards Tal, who is someone she disliked from the moment she saw him and never quite let go of it, but Tals condescending attitudes towards anyone who isn't a Chosen certainly don't help matters. Milla would have killed Tal if she'd had the chance. Tal simply wants rid of her. Nonetheless, they [[TeethClenchedTeamwork put their differences aside]] to fight the greater evil and accomplish their objectives, and while you could put that down to simple necessity, both Tal and Milla put their own lives in danger to save the other when necessary.
* Tash and Maga, in ''Literature/GalaxyOfFear''. Maga sees Tash's Force powers as taking attention from him, his tribe's garoo or shaman/leader. Tash thinks he hates her, and later has to confront her own racism towards someone whose people still wear skins and live as nomads.

[[/folder]]

[[folder: Live-Action TV ]]

* Frank Pembleton in HomicideLifeOnTheStreet is much like the Batman example. While Pembleton is an extremely talented detective, dedicated to his job and willing to see all murder victims as equals, he generally rubs those in his squad the wrong way, considering them amateurish by comparison. Having said that, his squad members get along with him considerably better than other members of the police force.
* Sherlock Holmes in ''Series/{{Sherlock}}'' and most of Scotland Yard.

[[/folder]]

[[folder: Pro Wrestling ]]

* This is pretty much the premise of any face vs. face feud in pro wrestling.
* JohnCena and [[DwayneJohnson The Rock]] are both supposed to be "heroes" (i.e., babyfaces-- Cena gets booed more than almost any other face ever, though), and they can't stand each other at all. Same applied to ShawnMichaels and TheUndertaker towards the end of the former's career, although that was more due to Michaels' ({{kayfabe}}) obsession with defeating Undertaker at WrestleMania.
** Cena also gets loads of this from RandyOrton after the latter's HeelFaceTurn.

[[/folder]]

[[folder: Video Games ]]

* In ''VideoGame/DragonAgeII'', this is very prevalent when it comes to both Fenris and Anders, both of whom have very strong opinions when it comes to the Mage/Templar conflict of the game. Fenris has a deep distrust of mages due to growing up as a slave in the Tevinter Imperium, an AlwaysChaoticEvil [[TheMagocracy Magocracy]], while Anders is an advocate of mage rights possessed by a spirit incapable of seeing shades of gray (to the extent that the spirit's influence eventually drives Anders to extremism). Unsurprisingly, the two ''despise'' each other - though Anders eventually becomes such an extremist that he sees nearly anyone as a potential enemy. Still, if there's one thing that the two agree on, it's that both of them dislike Merrill for being a Blood Mage (a very taboo and controversial form of magic in the setting).
** It's not just in ''VideoGame/DragonAgeII''. In the [[VideoGame/DragonAgeOrigins first game]], [[DorkKnight Alis]][[TheSnarkKnight tair]] and [[LadyOfBlackMagic Morr]][[TheSocialDarwinist igan]] hate each other from the first words they exchange and continue to exchange bile-filled insults throughout the entire game, right up until the end.
* Detective Cole Phelps and [[spoiler:DA Investigator Jack Kelso]] in ''VideoGame/LANoire''.
* [[VideoGame/LegacyOfKain Kain and Raziel]] are headbutting anti-heroes.
* ''Franchise/FinalFantasy'':
** Noel Kreiss to Snow Villers. in ''VideoGame/FinalFantasyXIII2''. They get over their differences pretty quickly, though.
** ''VideoGame/FinalFantasyXIII'': Before Noel, there was Lightning, who has the same issue. And that issue is also named Snow Villers.
* Most of the party in ''[[VideoGame/KnightsOfTheOldRepublic Star Wars: Knights of the Old Republic II]]'' harbors some kind of deep-seated dislike for at least one other crewmate. Bao-Dur can't stand Mandalore, Atton can't stand the Disciple, Brianna won't trust Visas, T3-M4 and HK-47 have a conversation that ends with a tazing, and ''nobody'' likes Kreia except the Exile herself.
* Lightning and Vaan are occasionally this in ''[[DissidiaFinalFantasy Dissidia 012]]''.
* Subverted with [[MortalKombat Johnny Cage]]; he butts head with the other fighters but is mainly on the receiving end rather than mutually dishing it out due to his often [[ArrogantKungFuGuy cocky]], [[ItsAllAboutMe narcissistic]], [[JerkAss jackass]] behavior. It only got worse [[MortalKombat2011 in the most recent installment.]]
* ''Franchise/MassEffect'': Jack and Miranda in ''2''; Jack endured hellish torture in a rogue Cerberus facility, Miranda is the biggest fan Cerberus has ever had, to the point where after you finish both their loyalty missions, they will attempt to kill each other and you have to separate them, costing you one's loyalty unless you have a high Paragon or Renegade score. A similar situation arises with Tali and Legion, since Tali really dislikes the geth and Legion ''is'' a geth. Finally, Javik gets into near-constant arguments with both EDI and a Paragon Shepard, EDI because he hates synthetic life and Shepard because the Protheans' default means of solving problems involved an airlock, while Paragon Shep tends to be more of a diplomat who tries to bring about a peaceful resolution. Thankfully, by the late-stage Citadel DLC, most of these settle down into at worst VitriolicBestBuds, and Legion and Tali's alliance ends up being the last, best hope for a geth/quarian peace.

[[/folder]]

[[folder: Web Comics ]]

* One of the main things driving the plot of ''Webcomic/{{Pacificators}}'' forward; [[ProperLady Muneca Powell]] and [[FieryRedhead Cinna Grossul]] do ''not'' [[{{Understatement}} get along]] at all.
* Bhatair Hollingsworth and Joshua Shephard of ''Webcomic/TheSilverEye'', while both being likable characters, hate each others' guts due to the bad blood between their [[FeudingFamilies families]], their [[RedOniBlueOni conflicting personalities]], and all the past insults between them.

[[/folder]]

[[folder: Web Original ]]

* ''[[LetsPlay/TwitchPlaysPokemon Twitch Plays Pokemon]]'' is this trope incarnate. It's most commonly seen with the fight between the Anarchists (followers of the Helix, who hold that the original play style is the best and that it's more fun that way) and the Democrats (followers of the Dome, who hold that democracy mode is necessary to progress and thus better). Nonetheless, both sides want the heroes to be successful, and will swap to the other style of play if necessary (best seen with the [[ThatOneLevel Safari]] [[TimedMission Zone]] in Red, for which democracy was practically ''required'', and the [[DidYouJustPunchOutCthulhu Arceus linking]] in Conquest, which really ''was'' impossible in democracy).


[[/folder]]

[[folder: Western Animation ]]

* Throughout the many ''WesternAnimation/TheLandBeforeTime'' films, Littlefoot and Cera avert this in the usual sense (except in the first movie, where it's played straight), but the trope holds true in the literal sense: at several points they've actually butted heads.
* ''WesternAnimation/BatmanTheAnimatedSeries'' gives us the titular Batman and Detective Harvey Bullock. Bullock would love nothing more than to see Batman behind bars, and Batman just flat-out can't stand Bullock. Their relationship comes ''this'' close to VitriolicBestBuds: they're at least willing to work together for the greater good, and Bullock is genuinely upset when he thinks Batman has died in ''The Man Who Killed Batman''.
