Alice and Bob 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 Lancer and his superior, since, while they may have animosity against each other, the Lancer deep down respects the Hero and will defer to his leadership. It's also different from Let's You and Him Fight, 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 practically never lead to them getting along. In fact, their animosity might even become a hindrance to the situation at hand, and they might 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, they could both grow more mature and understanding, and they'd STILL hate each other.
Examples of reasons for these characters hatred for each other might include:
- Racism: While this may seem like a reason that makes either or both of the heroes 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.
- Personality Clash: The heroes don't like each other because their personalities or philosophies just clash too harshly. Perhaps a Martial Pacifist is disgusted by an Anti-Hero's more bloodthirsty approach. Perhaps a Lawful Good / Lawful Neutral character is driven nuts by a Chaotic Good / Chaotic Neutral's more, um, chaotic approach. Perhaps The Stoic is irritated by the Boisterous Bruiser's tendency to boast.
- 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 Heroes 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 Lawful Good hero will hate your guts. Sociopathic heroes are also prone to this, for obvious reasons.
Subtrope of Divided We Fall that involves individuals rather than factions. Compare to Teeth-Clenched Teamwork, where, while hating each other, the heroes are willing to set aside their difference for the sake of doing what's right. Fighting the Lancer is when the teammates can't set aside their differences, and comes to blows. Compare Dueling Messiahs where it's both heroes who are like this with each other due to their conflicting methods in protecting the world. See also No Sympathy Between Mooks for the villainous version. Also contrast Villainous Friendship where two villains are the best of friends.
- In crossovers, Great Mazinger's Tetsuya Tsurugi and Getter Robo's Ryoma Nagare are often going at each other's throats.
- Kaede Rukawa and Hanamichi Sakuragi from Slam Dunk.
- Probably Un-Go'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. 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 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.
- Batman has a tendency to rub many other heroes the wrong way, with some of them actually going hostile on him. Superman is not one of them (which can surprise people, considering how opposite they are portrayed usually), but Hal Jordan and especially Guy Gardner are. Harvey Bullock is sometimes portrayed this way towards him too, but he eventually gets better.
Superman: He barely tolerated me.Wonder Woman: He loved you.
- With Hal Jordan, why they don't get along varies. Initially, it was because Bruce didn't trust Hal after his whole Parallax ordeal, but that was in modern times. Flashbacks show that they never really got along, with no clear reason aside from Hal hating Bruce being a jerkass and Bruce hating that Hal was loud and bright all the time. The New 52 changed this so that Hal was the jerkass from day one, while Bruce of all people was the chilled one.
- 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'. Of course, Miller's storyw as set in an alternate universe, and Byrne's only showed they're first meeting. Subsequent writers showed that Batman very quickly developed a friendship with Superman.
- And speaking of Guy Gardner, he REALLY has an ability to rub people wrong. Countless people have manifested the desire to beat the shit out of him. Batman actually did...WITH ONE PUNCH!!!
- The Hulk REALLY has this in spades. He has loads of characters he'll never get along with. Amongst them, Thor is the one with whom he has the biggest rivalry. The Juggernaut, Wolverine and 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 Planet Hulk / World War Hulk 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.
- The Punisher is a surprisingly dark anti-hero. He kills frequently in ways which are Bloody Hilarious, 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 Spider-Man, it's not surprising that Webhead isn't a fan.
You can't ever like Frank Castle, but you can sure as hell appreciate the man.
- The same thing goes for Daredevil, who has worked with the Punisher once or twice when he's had no other options. Anytime they meet is guaranteed to end in a fight, as the criminal Daredevil is trying to prosecute in that story is also the one Frank is trying to kill.
- Nick Fury is just about the only one who can vaguely get along with Castle. And even then, not for long. In one story, a Super Soldier gone wrong (as in, contagious uncontrollable Nigh Invulnerable vampire wrong) is finally defeated by Castle, but Fury allows its creator (and father) to live because his genius is needed by SHIELD (although he does end up unable to leave the island lab SHIELD leaves him in).
- Deadpool, due to his frequent work as a mercenary and assassin. Also, because everybody finds him freaking annoying. He's often paired with the aforementioned Punisher, the ultimate Straight Man who'll put a bullet in Deadpool's head despite knowing he'll regenerate, just to have two minutes' peace and quiet.
- Namor the Sub-Mariner has this with the Marvel Universe, primarily due to him being a royal Jerkass.
- 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.
- Ms. Marvel carried a grudge against Rogue for quite a while for 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 remembers that is up for grabs).
- Power & Glory 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.
- Sonic the Hedgehog and Knuckles the Echidna started off as this in the archie comics. Every time the two cross paths, they would act hostile towards one another and this ends up in the two fighting each other, usually due to ego. As time goes by, their antagonism towards each other would develop into a Friendly Rivalry.
- Hawkman and Green Arrow. Hawkman has a pretty conservative view of the world and has a kind of fascistic bent, due to either of his cultures (Carter Hall is a reincarnated Egyptian prince and Katar Hol is from an oppressive race full of Proud Warrior Race Guys), while Green Arrow is very liberal, to put it lightly. Later on, Ollie also brings up that Carter's creepy obsession with the new Hawkgirl, Kendra Saunders, borders on statutory, and that he's a 30-something man (biologically, chronologically he's at least twice that) while she's about 20. He also notes that Carter knows nothing about Kendra, instead expecting her to basically be Shiera, the previous Hawkgirl. Given Ollie's protectiveness of women, it was going to come up. The two have never gotten along, and Power Girl even invokes Feuding Families when discussing the Hawks and Arrows.
- Dungeon Keeper Ami 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 The Unfettered thrown in. The worst count as Omnicidal Maniacs. Mercury is nothing like this. The Light's forces, however, are extremely reluctant to consider her as anything but a madwoman to be eliminated. The Avatar outright states that he has difficulty tolerating 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.
- A Kantai Collection fic Eternity has Hiroshi Goto and Hina Togo, Admirals of Yokosuka and Kure districts respectively, share a strong mutual dislike, due to being near polar opposites. Goto is the half-american son of a shopkeeper who enlisted out of high school, became a mustang officer and worked long and hard to achieve his command, and was only promoted due to a lack of qualified flag officer candidates. Hina meanwhile is a descendant of Heihachiro Togo, the Nelson of the East, who was groomed for a naval career, has the midas touch, has had a fast and steady rise through the ranks, and was already a shoo-in for Admiral. Goto is jealous of Togo being a pampered ace who never had to lift a finger (which is not true), and Hina resents Hiroshi for successfully fighting the enemy while she looked like she had been kept out of combat for her own safety and/or abandoned her crew (which is also not true).
- Happens in The Avengers, 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.
- The film In the Heat of the Night gives us a rare look at a situation with realistic racism for our heroes to contend with. Tibbs is a black detective from Philadelphia. Gillespie is the chief of police of a small town in Mississippi. They have to work together to solve a murder, because Tibbs is an expert in forensics, and Gillespie has reluctantly asked for his help. The film's story revolves around Gillespie slowly overcoming his racism. Also, there's a murder.
- This sums up Tal and Millas relationship from book 1-4 of The Seventh Tower 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 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 Galaxy of Fear. 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.
- Frank Pembleton in Homicide: Life on the Street 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 Sherlock and most of Scotland Yard. Sherlock and pretty much everyone, in fact.
- Spike and Angel. Even when they were soulless they didn't really get along. In the fifth season of Angel, with souls, they still don't get along. At all.
- This is pretty much the premise of any face vs. face feud in pro wrestling.
- John Cena and 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 Shawn Michaels and The Undertaker towards the end of the former's career, although that was more due to Michaels' (kayfabe) obsession with defeating Undertaker at WrestleMania.
- In Dragon Age II, 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 Always Chaotic Evil 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, whereas Fenris might gain a great deal of respect for a Mage Hawke for their ability to control their powers and temptations, and compares Anders negatively to Hawke at a later point in the game. 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).
- If you have his DLC, Anders will also butt heads with Sebastian, a devoutly religious man. Since the Templars who are oppressing mages are bankrolled by the same Chantry that Sebastian supports, while Anders is an open heretic who (if you gave it to him) wears a medallion from the schismatic Tevinter Chantry under his clothes, there's just a bit of hostility there. When Anders goes off the deep end and commits a terrorist act in the name of mage freedom, if Hawke doesn't execute Anders immediately, Sebastian will storm off, eventually leading an army against Kirkwall in Dragon Age: Inquisition.
- Aveline (strongly Lawful-aligned city guard) and Isabela (strongly Chaotic-aligned pirate) will butt heads in the early- to mid-game, although they settle down to Vitriolic Best Buds later on.
- It's not just in Dragon Age II. In the first game, Alistair and Morrigan 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.
- Slightly lessened, but still somewhat prevalent in Dragon Age: Inquisition, usually from the part of Vivienne (a Pro-Circle Mage with classist views) and Solas (a spiritually-inclined Elven apostate contemptuous of all mortal races). The two tend to bitterly snipe at one another due to their completely opposing views.
- Detective Cole Phelps and DA Investigator Jack Kelso in L.A. Noire.
- Kain and Raziel are headbutting anti-heroes.
- Final Fantasy:
- Final Fantasy VII:
- At the beginning, Cloud and Barret can't stand each other. Barret apologises to him by the time they storm the Shinra building, saying he misjudged Cloud; Cloud doesn't return the affection until Barret's sidequest, when he grudgingly admits that "if you die on me, I'm gonna have nightmares". By the Compilation, they're best friends, and found-family.
- In Disc 2, Barret and Cait Sith are constantly at each other's throats. Barret hates Cait Sith for being a Shinra member and having kidnapped his daughter; Cait Sith resents Barret for being a terrorist whose attacks harm the innocent people he attempts to protect.
- Noel Kreiss to Snow Villers in Final Fantasy XIII-2. They get over their differences pretty quickly, though.
- Final Fantasy XIII: Before Noel, there was Lightning, who has the same issue. And that issue is also named Snow Villers.
- Final Fantasy VII:
- Most of the party in 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 Dissidia 012.
- Subverted with 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 cocky, narcissistic, Jerkass behavior. It only got worse in the most recent installment.
- Evolved in Mortal Kombat X. Johnny can still be a complete ass at times, but he does back up his cocky attitude with legitimate badassitude, being instrumental in defeating Shinnok, making an effective diplomat with the other factions of the MK-verse, and is recognized several times as being Earthrealm's champion. And he's a good dad too.
- Mass Effect: 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 Vitriolic Best Buds, Javik comes to have a great deal of respect for Shepard and his/her idealism, and Legion and Tali's alliance ends up being the last, best hope for a geth/quarian peace.
- The King Of Fighters: Kyo Kusanagi and Iori Yagami are always ready to go at each other. Killing Kyo seemingly the only goal of Iori's life. This is troublesome because these two are part of a trio who hold the to seal away Orochi. They manage to come together for the sake of humanity in some games. Said games usually end in a clash between the two with an Unresolved Conflict.
- One of the main things driving the plot of Pacificators forward; Muneca Powell and Cinna Grossul do not get along at all.
- Bhatair Hollingsworth and Joshua Shephard of The Silver Eye, while both being likable characters, hate each others' guts due to the bad blood between their families, their conflicting personalities, and all the past insults between them.
- Twitch Plays Pokémon features this trope being carried out by the legions of players controlling the player character at the same time. 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 Safari Zone in Red, for which democracy was practically required, and the Arceus linking in Conquest, which really was impossible in democracy).
- Throughout the many The Land Before Time 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.
- Batman: The Animated Series 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 Vitriolic Best Buds: 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.
