== Rivalries == 
[[File:Moloc.JPG|300px|right|thumb|Everyone hates the Minotaurs]]
While normally above mortal shortcomings, the greatest flaw of the Space Marines is their hubris. They are immensely proud warriors who do not take kindly to having their honor slighted. Some take mental note of this for a later date while others [[rip and tear|take the more direct approach]]. This has created some notable rivalries between the various Chapters, some of which date back to the Great Crusade.

*'''Space Wolves and Dark Angels''' - The Space Wolves and Dark Angels have a rather tumultuous and sometimes violent rivalry, but in a way their Legions truly reflect the relationship between brothers. The rivalry itself stems from a confrontation between their Primarchs that stemmed from the different cultures the Primarchs had come up in. During a joint operation between the Wolves and the Dark Angels, the planet's ruler had insulted Russ personally, so Russ resolved to slay him personally. The Lion tried to cut Russ in on his deep strike plan, but Russ would have none of it. He didn't want to defeat the enemy, he wanted to utterly crush them. Frustrated with his brother's lack of cooperation, the Lion launched his strike without the Wolves' help, and Russ fought his way into the planetary ruler's palace just in time to watch the Lion behead him. Furious, Russ threw down his weapons and punched the Lion, starting a lengthy fist fight that only ended when Russ started laughing upon realizing how pointless the fight was and how stupid he'd been. Thinking that Russ was laughing at him, the Lion punched Russ unconscious. When Russ awoke he sought out the Lion to make amends, but he had already departed with his fleet. Though the two would work together again, the Lion was rather unforgiving (oh the irony) towards Russ. To Russ the Lion seemed the antagonist. After all, in the halls of Fenris a brawl between angry brothers was hardly unusual. When the fight ended you'd toast each other and drink away the bruises and move on. To the Lion Russ seemed at fault. After all, in the knightly orders of Caliban striking one's brothers was not done: petty infighting could not be tolerated when monsters slavered at the gate. As is so often the case between brothers, both were at fault and neither would back down. To this day the Space Wolves and Dark Angels (and their successor Chapters) will fight (usually) non-lethal honor duels to "settle the score," though "the score" has never really been agreed on. Occasionally tensions between the two Chapters will boil over into open warfare which is often caused by <strike>Fallen Angels</strike> TRAITORS UNASSOCIATED WITH THE DARK ANGELS hiding amidst the Space Wolves' protectorate worlds, using the tensions to their advantage. Finally it's worth noting that even though the two (former) Legions often fight, they never show that rivalry to the wider Imperium, and they'll set aside their rivalry whenever they need to [[get shit done]] together. Their rivalry is in question now, though, as after the Great Rift opened the Unforgiven came and beat the shit out of Magnus’s army invading Fenris. Originally they thought the sudden explosion of Wulfen numbers meant that the Space Wolves either fell to Chaos, were too mutated to recover and needed a mercy killing, or that there would hardly be any left and just Wulfen remained. Unlike when the last time they showed up at Fenris and attacked the Space Wolves in the belief the Wolves had turned or something, this time the Dark Angels were wary of being used and found out that their assumption was wrong before they could fuck up and thus avoided epic team-killing and instead the First Legion slammed into the daemons and traitor Marines like the Emperor’s own banhammer.

*'''Ultramarines and the Word Bearers''' - The Ultramarines are pissed off at the Word Bearers for a great many things: 1) They turned traitor during what was supposed to be an exercise to patch up their poor relations after the Castigation of Lorgar; 2) They used millions of cultists as meat shields during the [[Battle of Calth]], which the Ultramarines saw as dishonorable and disgusting; 3) They almost destroyed Calth; and finally 4) The battle of Calth was the first battle of the Heresy for the Ultramarines as a whole, meaning that while they were chilling and waiting to go kill some Orks, the Word Bearers suddenly turned around and slaughtered a fuckload of them without warning. They managed to pull through in the end and win by the skins of their teeth, but it was a gigantic blow to the Ultramarines, who now had to fight off a vengeful Legion out of nowhere with almost half their Legion dead, their fleet crippled, ''and the fucking sun of the planet they were on flooding it with deadly radiation''. Not to mention the giant Warp storm that cut them off from the rest of the Imperium, which coincidentally formed at the exact time the Word Bearers attacked...

*'''Ultramarines and the Alpha Legion''' - The Alpha Legion led the Ultramarines halfway across the galaxy on a fool's errand that ultimately ensured they were nowhere near the Imperial Palace during the Horus Heresy. Adding insult to injury, they inflicted enormous casualties on the Ultramarines, and though they succeeded in killing Alpharius (or did they?), the Alpha Legion's command structure was so decentralized that it did little to affect them.

*'''Ultramarines and the Black Templars (also the Imperial Fists, the Crimson Fists, the Space Wolves, and the Salamanders)''' - When Roboute Guilliman tried to force the Codex Astartes on the Space Marine Legions after the Horus Heresy, some Legions - most notably the Imperial Fists - outright refused, not wanting their legions to be broken down into smaller Chapters. Rogal Dorn called Guilliman a coward, while Guilliman called Dorn a rebel. The Space Wolves and the Salamanders ended up backing Dorn, while the Raven Guard and the White Scars supported Guilliman. The rivalry became so intense that the Imperial Navy even fired on the Imperial Fist strike cruiser ''Terrible Angel'', and it seemed that the Space Marines would war against one another once again. Finally, Rogal Dorn yielded to prevent another war and broke his legion into the Black Templars and the Crimson Fists. As the Ultramarines still were wary of the loyalties of the Imperial Fists and their successors, Sigismund - the first Emperor's Champion and the man that Dorn had appointed to be the Black Templars Chapter Master - declared a 10,000 year crusade in the Emperor's name to prove their loyalty. Even though tensions have since cooled between the Ultramarines and the other Chapters, the Ultramarines are still suspicious about (read: sticking their nose into the business of) the Black Templars as they still refuse to conform to the Codex Astartes, and won't tell the Ultramarines just how huge their Chapter is. In short, Sigismund and Leman Russ told Guilliman where he can shove his Codex Astartes, and he's all anal pained about it.

*'''Ultramarines and the Iron Warriors''' - [[Uriel Ventris]] and Pasanius Lysane, of the Ultramarines, were sworn to a Death Oath by their Chapter Master Marneus Calgar as punishment for violating the Codex Astartes (specifically, because they had abandoned the rest of their company to assist a Deathwatch Kill-team during the Battle of Tarsus Ultra). Their mission: find and destroy the [[Daemonculaba]]. The quest took the Ultramarines pair to the nightmarish [[Daemon World]] of [[Medrengard]], within the [[Eye of Terror]] itself. Medrengard was the homeworld of the Iron Warriors Traitor Legion. It was also the location of [[Honsou]], the evil Iron Warriors Warsmith who oversaw the Daemonculaba project from within his fortress, Khalan-Ghol. The Ultramarines were successful in destroying the Daemonculaba, and were also able to bring ruination to Khalan-Ghol and Honsou's forces. Uriel Ventris also managed to shoot Honsou in the head. Unfortunately, the Warsmith survived the headshot. Upon realizing the extent of the damage Uriel had caused, Honsou swore revenge and also the utter annihilation of [[Ultramar]]. Honsou was aware that before he ever dealt with Uriel Ventris, the Ultramarines spent years and countless resources and lives to repel a [[Tyranid]] incursion at Tarsis Ultra. Honsou thus unleashed a plan which destroyed every living thing on Tarsis Ultra, and reduced the planet itself to a lifeless rock. Destroying the planet provided no strategic gain to the Iron Warriors; Honsou carried out his horrific genocide simply to spite Uriel Ventris and the Ultramarines. Following this, the Iron Warriors use an army won from the [[Red Corsairs]] to free the [[Daemon Prince]] [[M'kar]], and invade [[Ultramar]]. Though the "Bloodborn" army is beaten back, the Ultramarines lost over one third of their battle-brothers in the attempt, leaving them open to attack for the first time since the First Tyrannic War and unable to properly participate in the Imperial counter-offensive for the [[13th Black Crusade]]. The Ultramarines and the Iron Warriors have thus become bitter enemies-- with Uriel Ventris and Honsou in particular becoming sworn foes.

*'''Ultramarines and the Hammers of Dorn''' - The Hammers adhere rigidly to the Codex Astartes, to the point where they point out any deviations from the codex by the Ultramarines. According to the Hammers of Dorn, Guilliman may have had the genius to pen the codex, but the sons of Dorn are the only ones that can bring out its full potential.

*'''Ultramarines and the Minotaurs''' - While the Minotaurs are hated by everyone the Ultramarines have a special grudge against them, due to the Euxine Incident of the [[Macharian Heresy]]. It just so happened that the loyalist [[Doom Warriors]] and [[Inceptors]] chapters were busy [[skub|fighting each other over a matter of honor]], and [[lawful stupid|refused to stop and aid Imperial forces]]. The Minotaurs were sent to quell the dispute, which they did in their [[rip and tear|usual manner]]. They attacked both sides in force, nearly destroying them wholesale. The Doom Warriors were badly beaten and forced into a barely-organized retreat almost immediately. The Inceptors weren't so lucky. With no way to withdraw they suffered the full onslaught of the Minotaurs and finally surrendered with less then 100 Marines left. The honored 2nd [[Founding]] Chapter was subsequently [[Blood Ravens|robbed of most of their Chapter relics, the Minotaurs stealing them right off their dead bodies]], including their flagship, a relic of the Great Crusade. This brought them a great deal of hatred from the Ultramarines and their successors, who have since forbidden the Minotaurs from entering Ultramar and seek vengeance whenever the opportunity arises.

*'''Blood Angels and the World Eaters''' - Both constantly compete for superiority in melee combat and also the angriest motherfucking berserker full of rage.

*'''Raven Guard and White Scars''' - Supposedly dates back to a huge fucking argument between [[Corax]] and [[Jaghatai Khan]], where the two had a massive spat over the proper use of rapid-reaction forces. Corax insisted they be used as part of infiltration and deep-strike units, and Jaghatai insisted they were to be on the front lines - the two never really saw eye-to-eye, Corax seeing Jaghatai as devastatingly effective, but with the tactical sense of a drunken Space Wolf, and Jaghatai seeing Corax as too cautious and tactical for proper man-fighting. The two would eventually make up after the Horus Heresy, and both the Raven Guard and White Scars would be forced to ally on several occasions - most notably during the infamous Hunt for Voldorius - but an intense rivalry over whose fast-attack doctrine is better persists to this day, and the two factions are still kind of assholes to one another as a result.

*'''Blood Angels and the Black Legion''' - Considering that Horus killed their Primarch (who, before the Heresy, were closer than any other Primarchs) which resulted in them suffering from the Black Rage which eventually causes every descendant of Sanguinius to have visions of being killed by Horus, the Blood Angels probably despise the Black Legion to the point of pure obsession. Also as a rule, the Blood Angels have a special hatred for the [[Abaddon|owner]] of the '''Talon of Horus''', since it killed their <s>father</s> sexy angel daddy.

*'''World Eaters and the Grey Knights''' - Angron was banished back to the Warp by Grey Knights during the first battle of Armageddon, which resulted in the World Eaters' defeat. Angron has since been resurfacing, and has sworn revenge.

*'''Raven Guard and the Black Legion (also the Word Bearers, Night Lords, Iron Warriors, and Alpha Legion)''' - The Raven Guard were the second hardest hit by the Drop Site Massacre of Istvaan V ''(the Salamanders got hit worse, but there weren't really enough survivors to hold a grudge)''. Though all of the traitor legions except the Thousand Sons were involved, the Raven Guard holds a special hatred for the former Luna Wolves and Horus, a hatred which has transferred over to [[Abaddon]] and the Black Legion. That said, the Raven Guard go absolutely murderous on any of the Legions who turned on them at Istvaan V.

*'''Grey Knights and the Space Wolves''' - Officially, there really isn't a rivalry at all. Because officially the Grey Knights don't exist. Unofficially, during the First War for Armageddon, Grey Knights were ordered to fire on dozens of civilian ships because there was a fraction of a shadow of smidgen of a chance that they were tainted by Chaos. The Space Wolves decided this was pretty dickish, and protected the civilians. Naturally, the Inquisition made it worse. Then old [[Logan Grimnar|Loggy]] chops a Grey Knight Grand Master's head off and kills four Justicars, the ugly downward spiral of '''''WTF!?'''''s started there. Eventually, an understanding was reached where the remaining civvies weren't murdered but just mindwiped a bit and Inquisitorial ships would never again come to Fenris or the Wolves would tear them a new asshole. Officially unofficially, the Grey Knights are angry that another Chapter was given even shittier writing than they got.

*'''Imperial Fists and the Iron Warriors''' - Imagine their rivalry akin to World War I. The Imperial Fists love making defenses, while the Iron Warriors love destroying stuff. Perturabo hated Rogal Dorn for being Daddy's golden boy and his constant boasting of the fortifications of the Imperial Palace. Perturabo eventually bested Dorn and the Imperial Fists by making a huge space fortress that Dorn then tried to attack in an effort to bring Perturabo to justice (known as the 'Iron Cage'). The fortress was nothing but a decoy with inwardly facing gun-lines, meaning the entire thing was a trap and wound up cutting down enormous numbers of the Imperial Fists before they could retreat. Each side was too strong without both of them completely destroying each other. Dorn is still perturbed to this day by the event.

*'''Thousand Sons and the Space Wolves''' - The Space Wolves despised the Red Sorcerers for their practice of magic, and initially didn't question a goddamned thing after Horus had intentionally given the Wolves incorrect orders (to destroy the Thousand Sons, as opposed to taking Magnus to stand trial). Perhaps the dumbest part of their rivalry is that when they actually showed up at Prospero, Leman Russ felt guilty about just slaughtering the Thousand Sons, so he tried to call Magnus to ask him to stand down so that they could take him in peacefully. Magnus, having assumed Leman Russ was here to kill him had refused to take any calls (and not only prevented his Legion from communicating with the Wolves, but gathered them all so they'd be easier to slaughter) which ended up pissing off the Wolves again and ensuring the Thousand Sons were nearly completely wiped out. Despite this being entirely preventable by their Primarch (on top of causing their fall to Tzeentch) and engineered by Horus (with the Wolves being completely ignorant about it) they still blame the Wolves anyway instead of those [[Derp|other two]]. The Sons would nonetheless resurface to attack the Space Wolves: they led a siege on their homeworld and succeeded in causing considerable damage before being driven off; during this offensive they managed to destroy a series of laboratories, including one that held an entire generation worth of the Space Wolves' Gene-Seed (as well as the cure for the Wulfen curse), and Magnus himself was responsible for killing the Space Wolves' Chapter Master.

*'''White Scars and the Space Wolves''' - Thousand Sons were the biggest bros of the Scars during the Great Crusade, their Primarchs were total bros too, so when they figured out that Wolves destroyed Prospero, killed most of the (still totally loyal) Thousand Sons and Magnus forced the surviving ones into going heretic (though some were [[Traitor Legion Loyalists|already corrupted prior]]) (and the Wolves don't even feel any guilt or remorse about their role), none were surprised the Scars kept a huge grudge against the Space Yiffs. Also during the Crusade, the Scars hated being compared to the Wolves because of the apparent link to barbarism. The Wolves themselves also have a thing or two to say about the multiple times Scars hadn't come to help when they could, starting from when they left the Wolves alone against an entire Alpha Legion fleet.

*'''White Scars and Death Guard''' - Mostly a personal one between Jaghatai Khan and Mortarion, but there was no love lost to begin with. Solidified when the Khan cut Mortarion's head off and killed his physical body at the Siege of Terra, forcing him to assume a Daemonic form.

*'''Iron Hands and the Emperor's Children''' - Prior to the Heresy, Fulgrim and Ferrus Manus were '''extremely''' close friends. Their bond ran so deep that even as Fulgrim declared his intentions of joining the forces of Chaos to Ferrus, asking him to join him in overthrowing the Emperor, Ferrus couldn't open fire on his brother's ship. Naturally, this had some rather nasty effects in the long term, not least of which was Fulgrim decapitating the Gorgon with his own sword. The Iron Hands did not take kindly to this. Also, getting all repressed and logical over the next 10,000 years caused Slaanesh to take breaking them as a challenge.

*'''World Eaters and The Emperor's Children''' - In addition to following [[Khorne|rival]] [[Slaanesh|deities]], the Emperor's Children lost huge numbers of troops to the World Eaters at [[Battle of Skalathrax|Skalathrax]]. Really, all you need to know is that [[Kharn]] and a Flamer were involved, and that before this incident, the World Eaters were a much more coordinated force.
**'''World Eaters and World Eaters''' - This event caused the World Eaters to break up into warbands.

*'''Emperor's Children and the Iron Warriors''' - Given that Fulgrim tried to sacrifice Peturabo's soul to Slaanesh to fuel his ascension to Daemon Prince...
** '''Emperor's Children and absolutely everyone else''' - Due to their disturbing habits of enslaving populations and/or stealing other Legion's servants to be used as... [[Slaanesh|''partners'']] for [[/d/|some memorable parties]], absolutely everyone tend to avoid them like walking STD's.

*'''Dark Angels and FOUL TRAITORS''' - Do ''not'' get between them and a [[Fallen Angels|FOUL TRAITOR TO THE IMPERIUM WHO CERTAINLY HAS NO CONNECTION TO THE SONS OF THE LION]]. It can only end in tears.

*'''Thousand Sons and World Eaters:''' Khorne hates sorcery, and so the World Eaters hate the Sons. Sadly for the World Eaters, they're usually well out of the Sons' league; the Thousand Sons tend to pick conflicts selectively, which means the followers of Khorne have rarely even had the chance to fight them. Also, it doesn't do much to appease Khorne's bloodlust, since there is no blood or skulls to offer, just dust. Then again, there are some exceptions, namely [[Iskandar Khayon]] and [[Lheorvine Ukris]], who were total bros, and they were the guys that founded the [[Black Legion]] along with [[Abaddon]].

*'''Blood Ravens and EVERYONE:''' Apart from Captain Titus of the Ultramarines, almost every Marine Chapter mentioned in having contact with the Blood Ravens have not been on good terms. Most likely due to their rampant kleptomania. This animosity extends beyond the Space Marines, and into the rest of the Imperium as well; Imperial Guard forces hate them for exterminating the Kronus Liberators, the Mechanicus hates them stealing archeotech, the Ecclesiarchy hates them for their psykers, and the Inquisition doesn't like them for their secrecy.

*'''Blood Angels and the Emperor's Children''' - [[Fabius Bile]] stole the blood of Sanguinius from the Blood Angels' Fortress-Monastery as part of a plot to make a clone of the God-Emperor. As the neophyte initiation process for the Blood Angels requires the consumption of some of the aforementioned blood, the Blood Angels and all their Successor Chapters have sworn to find and kill Bile at all costs. (For a while, it looked like they succeeded—that is, until they found out that Bile had begun cloning ''himself''.)

*'''Iron Hands and Raven Guard and Salamanders''' - The Iron Hands are still pissy about the whole [[Drop Site Massacre|Isstvan V]] thing. They believe that had the Salamanders and Raven Guard followed their Primarch Ferrus Manus they would have won at the Dropsite Massacre. Completely overlooking the fact that they were surprised, surrounded, outgunned and outnumbered nearly 3 to 1. They don't like the Raven Guard in particular for their use of stealth and subterfuge, and also for having a pretty much identical color scheme. The Salamanders aren't too keen about the Iron Hands belief of "purging the weak" and usual disregard for civilian casualties and sometimes their own Marines. The Raven Guard and Salamanders never pulled any of this bullshit with each other, though, and remain close allies, if for nothing other than the Hands constantly being dicks to both of them.

*'''Marines Malevolent and Salamanders''' - What happens when the galaxy's [[That Guy|greatest assholes]] meet the galaxy's greatest humanitarian Marines? Hilarity, that's what. The hate fueled rivalry that was first widely known came during the Third War for Armageddon where a squad of Marines Malevolent used their [[Whirlwind|Whirlwinds]] to fire upon an Ork-occupied camp, when they ''knew'' that the camp contained hundreds of Imperial civilian hostages, mostly women and children. Oh and guess what their response was, something to do with "Meh, we only serve the Emprah only" and "We didn't know there were ''"that"'' many civilians." As you can imagine, this both horrified and [[Rage|royally pissed off]] the Salamanders, and when these two Chapters met again after the war, Chapter Master Tu'Shan, to put it simply, bitch-slapped the Captain of the Marines Malevolent in front of ''everybody in the city,'' prompting much sniggering and cheering among both Guardsmen and civilians alike. Because of such reaction to complete dickwads, the Salamanders were considered as the '''Heroes of Armageddon''' by popular vote.

*'''Aurora Chapter and the Emperor's Spears''' - Fought each other over matters of honor and the Ultramarines judged Aurora Chapter was right, which soured relations of the Emperor's Spears with their primogenitor. Tensions have since lessened but the two Chapters still refuse to fight together.

*'''Marines Malevolent and Everyone Else''' - When even [[GW|GeeDubs]] canonically calls them "the worst"... well, 'nuff said.

*'''Salamanders and Sons of Medusa''' - During the [[Badab War]] the Salamanders, being friends with the [[Executioners]] chapter (who had been on the wrong side of the fighting), prevented the [[Sons of Medusa]] from taking revenge for the Strike Cruiser Warspite, lost with all hands at the hands of the Executioners, after the Executioners surrendered. The Sons of Medusa have sworn off all contact with the Salamanders and basically implied they would rather see the Imperium lose wars than help a single Salamander live.

*'''Iron Hands and Successors (especially Red Talons) and Sons of Medusa'''- The Sons of Medusa were formed from Iron Hands and successor Chapter Marines except those from the [[Red Talons]] who professed their belief in the Moirae Doctrine during the [[Nova Terra Interregnum]]'s Moirae Schism. The Red Talons killed all of their schismatics but all other Schismatics essentially formed their own Chapter, which was judged pure by the restored [[High Lords of Terra]] near the end of the [[Age of Apostasy]] and given official recognition outside of normal Chapter Foundings as the Sons of Medusa. The mainstream believers in the [[Omnissiah]] amidst the Iron Hands and all other successors obviously have serious problem with this, but can't act against the Sons of Medusa due to them being officially recognized as a Chapter. Further, the Sons of Medusa outperformed all other Iron Hands successors during the major Crusades whose ending marked the beginning of the [[Age of Redemption]], formally earning the respect of Imperial military bureaucracy and erasing any suspicions over their being specially recognized rather than normally founded. The Sons of Medusa for their part see the mainstream Iron Hands and successors as fools who cling to ancient doctrine over the reality of the situation at hand.

*'''Lamenters and Reality Itself''' - Again, enough said.

*'''Fire Angels and Space Sharks'''- The [[Fire Angels]] refused to fight alongside the [[Space Sharks]] during the Badab War, implying some bad blood between the chapters though the severity is unknown.
