[[folder: Multiple Character Tropes]]
* BadassFamily: Though who's related to whom varies wildly DependingOnTheAuthor.
* BloodKnight: Knights were expected, as a matter of honour, to go adventuring on a regular basis, and are generally more than happy to do so. The ones who make an attempt at settling down (as Ywaine did) get badgered back into it pretty quickly.
* DefeatMeansFriendship: Not always, but pretty frequently.
* DependingOnTheWriter: Who appears,who has major and minor roles, who is related to whom, how characters act... and pretty much everything else.
* LawOfInverseFertility: Arthur and Guinevere are generally never given any biological children together (excluding Arthur’s sons Llacheu/Loholt/Borre) whilst Arthur and Morgause only need to copulate once to produce Mordred in tellings involving this BrotherSisterIncest.
* OddNameOut: King Arthur's nephews are Gawain, Gaheris, Gareth, Agravaine, and Mordred. Guess which ones are evil.
* OneSteveLimit: Averted. There are several women named Elaine, and there are several different women who occassionally share the title "Lady of the Lake". There are also three Iseults--Tristram's lover (Iseult "the Fair"), her mother, and another princess who Tristram marries (Iseult "of the White Hands"). There are also two Ectors, Arthur's foster-father Ector and Lancelot's half-brother Ector de Maris, and two men named Bors, King Bors and his son Bors of the Round Table.
* RoyalsWhoActuallyDoSomething: A great number of knights start out as royalty or nobility, others tend to get lands and castles pretty quickly.
* [[SirNotAppearingInThisTrailer Sir Not Appearing In This Book]]: Merlin's liege, Master Blaise, is mentioned once in passing but never appears nor does anything to affect the plot.
* SpellMyNameWithAnS: Variant spellings of names abound. Some distinct characters may have even resulted from people interpreting spelling variations as different people (ex. Morgause and Morgan). A manuscript of a work may even have different spellings for a name, which can then differ with other manuscripts of that same work (ex. Guinevere).

[[folder: Guinevere]]
%%* ActionGirl: Some portrayals of her.%%ZCE
%%* TheChick: TropeCodifier.%ZCE -- how is she the Chick, and how is she the trope codifier?
* {{Chickification}}: Perhaps the UrExample. While in most Arthurian stories from the 13th century onwards she's not action-oriented at all, in the oldest Welsh tales she was a badass warrior and magic-user. Only very recently have we seen a swing of the pendulum back in favor of more ActionGirl-esque portrayals.
* DamselInDistress: One of the oldest motifs about her is that she's abducted by a jealous rival of Arthur. She's rescued by Arthur and his crew, or in later works Lancelot.
* EvilTwin:
** Well, identical half-sister. On the same night Leodegrance fathered Guinevere, he also begat another girl on the wife of his seneschal. This "False Guinevere" was born on the same day, looked exactly like her half-sister and even had the same name (Leodegrance had strong genes, but it looks like he wasn't very imaginative). She managed to trick Arthur into thinking the was the real deal, and tried to have Guinevere mutilated and banished (with Lancelot's help, she escaped). "False Guinevere" kept the charade up for ''years'' until the Pope himself stepped in and demanded Arthur take the real Guinevere back. He refused, and the Pope interdicted Britain for twenty-one months. After ten, "False Guinevere" had a stroke, lost every sense but sight and hearing, then began to rot alive, until she finally confessed and perished.
** The ancient Welsh have left an early precursor version of the same archetype: apparently, the reason the Welsh Arthur and Mordred die at Camlann is because [[TheGloriousWarOfSisterlyRivalry Gwenhwyfar and her sister Gwenhwyfache got into a fight over chestnuts]]. Modern versions of this legend traditionally make Gwenhwyfache Mordred's [[UnholyMatrimony wife.]]
*** The blow Gwenhwyfach delivered to Gwenhwyfar resulted in Camlan and is one of the Three Unfortunate Blows (or hard slaps) in Welsh tradition. Striking a queen was one of the three ways of disgracing her.
* GodSaveUsFromTheQueen: She varies between this and TheHighQueen in several iterations or even she is a hybrid of both.
* FaceHeelTurn: One version of the story has her eagerly joining up with Mordred's rebellion, bearing him two children, and eventually getting executed by Lancelot.
* GrayEyes: According to ''Sir Gawaine And The Green Knight''.
* LoveTriangle: At the center of the most famous one of all time.
* SmartPeoplePlayChess: Apparently one of the most skilled players in the court.
* SpellMyNameWithAnS: Guenevere, Guenever, etc. The Welsh form is Gwenhwyfar. (A modern equivalent is Jennifer.) In just one manuscript of Geoffrey of Monmouth's ''[[Literature/HistoriaRegumBritanniae History of the Kings of Britain]]'', Guinevere's name is spelled differently every time she's mentioned (Ganhumara, Ganhumera, Guenhumara, Guenhuuara). Other manuscripts have more variations.
%%* TheHighQueen
%%* {{Tsundere}}
* TwoGuysAndAGirl: With Arthur and Lancelot, as one of the oldest examples of this trope.
%%* WorldsMostBeautifulWoman
* YourCheatingHeart:
** Her affair with Lancelot is usually kind of a "bad move" for the round table's morale.
** In earlier versions of the legend, she has an affair with Mordred.

!Knights of the Round Table

[[folder: Lancelot]]
Lancelot's first appearnace is notable for being unfinished by Chretian De Troyes, although some scholars once held a theory that he was based on Lleu of the 4th Branch of the Mabinogion. Some think this is because his patron, one of Eleanor of Aquitaine's daughters, may have ordered him to add the infamous affair with Guinevere. In other words, it's possible the entire crux of a huge portion of the Arthurian Romances was the result of a lady wanting to turn an adventure story into the medieval equivalent of a Harlequin Romance novel.
* AccidentalPornomancer: Aside from his affair with Guinevere, he was raped twice. Once by Lady Elaine and again by Brisen, Lady Elane's servant.
* TheAce: Usually the best warrior in the story, with his affair with Guinevere preventing him from being the "perfect" knight. Includes MasterSwordsman, Master Lancer, Master Horseman, etc...
* AesopAmnesia: After the Grail Quest, he forgets everything he learned about purity and all that and starts sleeping with Guinevere again.
* TheAtoner: Most of his quest for the Holy Grail is him atoning for his sins.
* TheBerserker: Something Film/MontyPythonAndTheHolyGrail definitely got right is that Lancelot tended to leave high body counts behind him, often of relatively innocent people.
%%* BloodKnight
* CoolSword: Arondight, though he used one called Secace/Sequence (which he may have borrowed from Arthur) for the battle at Saxon Rock.
* DisproportionateRetribution: More than once, Lancelot, while he was out wandering, would wander into other knights' pavilions and make himself at home. When confronted by the understandably upset owners, well, [[ForegoneConclusion he's Lancelot and they're generally nameless.]]
* EvenTheGuysWantHim: One of Arthur's rivals for the throne, Galehaut, certainly did.
* FatalFlaw: His illicit affair with Guinevere proves to be the undoing of the Round Table itself.
%%* GoodIsNotNice
%%* HotBlooded
* {{Hunk}}: Usually depicted this way, except in ''Literature/TheOnceAndFutureKing'' where he is called "The Ill-Made Knight" because he is ugly.
* KillTheOnesYouLove: One version of the story has him executing Guinevere after she betrays Arthur and joins Mordred in his bid to rule England.
* NumberTwo: Sometimes depicted like this, but in the tales he isn't because his knight-errantry gets in the way.
* RoyalsWhoActuallyDoSomething: Son of King Ban of Benwick, with King Lancelot his maternal grandfather.
* SailorEarth: It's generally agreed that he wasn't introduced into the myths until the twelfth century.
** His earliest appearances are in the works of Creator/ChretienDeTroyes. He first appears in ''Erec and Enide'' as the third-greatest knight of Arthur, after Gawain and the hero Erec, but nothing else is said of him. He next appears in ''Cliges'', where he loses to the hero Cliges in a joust. He gets star billing in ''Lancelot, Knight of the Cart'', which establishes him as the best knight and his CourtlyLove for Guinevere, and he became a BreakoutCharacter thereafter.
** Older scholarship has linked him to the Welsh Arthurian figure of Llwch Llenlleawg ("Llwch of the Striking Hand"), because their names kind of look alike, and more pertinently "llwch" is the Welsh word for "lake" while Lancelot's full name is Lancelot du Lac or Lancelot of the Lake. The drawback is that Lancelot and Llenleawg have little in common, so treating him as a CanonForeigner is the most favored theory nowadays. Other times he would be linked to Lleu of the Fourth Branch of the Mabinogion. Or Llenlleog the Irishman, although that’s rare.
* SixthRanger: He doesn't show up at the Round Table until long after it's assembled.
* SpellMyNameWithAnS:: Sometimes spelled "Launcelot".

[[folder: Gawain]]
* TheAce: Earlier stories suggest he was originally Arthur's best warrior and one of the successful heroes of the Grail quest. Adds a new light to his rivalry with Lancelot, doesn't it?
* AwesomeMcCoolName: His Welsh counterpart's name Gwalchmai (Gwalchmei) is usually interpreted as "Hawk of May" or "Hawk of the Plain". Gwalchmai’s brother was Gwalhafed, and that name was interpreted to mean “Hawk of Summer.”
* TheBigGuy: TropeCodifier.
* BraveScot: Usually associated with Lothian and/or the Orkney islands, both part of Scotland.
* CainAndAbel: In stories where Gawain has more presence, he becomes the Abel to Mordred's Cain; one telling of the legend carries the trope out to it's ultimate fulfillment, with Mordred killing Gawain in a final duel before Arthur and Mordred's date with destiny.
* ChickMagnet: In both Mallory's take and in Gawain and the Green Knight, he is glomped on by a female paramour with him doing nothing to attract their attention. With the lady of the Green Knight, he refutes her advances, because it wouldn't be honorable.
* ChivalrousPervert: He's definitely willing to reciprocate other advances though. And he's even willing to honor deals with less beautiful women like Ragnell, which ends up getting her being smoking hot and him being a proto-feminist.
* ClearMyName: One of his adventures in ''Parzival'' has him doing this.
* CoolSword: In some versions of the story, Arthur lends him Excalibur for a while, in others he uses a sword named Galatine.
* FamilyHonor: Gawain's main motivation, at least in ''Literature/LeMorteDarthur''.
* HenpeckedHusband: he plays this role to Lady Orgeleuse in ''Parzival''.
* HeterosexualLifePartners: With Percival (who, in some stories, is his cousin). They swear eternal friendship after Gawain sees Percival [[CurbStompBattle soundly beat Kay]].
* IndyPloy: One episode in Creator/ChretienDeTroyes's ''Perceval'' and Wolfram von Eschenbach's ''Parzival'' has him holding off an angry horde of townspeople while using a chess board as a shield. Of course, the chess pieces are described as being ten times as large as normal ones, and are also used as impromptu missile weapons at one point, so (assuming a board of equivalent size) that's actually not too impractical.
* InterspeciesRomance: Has a one-night stand with the fairy Blanchemal, leading to the birth of Sir Gingalain, aka La Bel Inconnu.
* NomDeMom: His Welsh counterpart Gwalchmai ''ap Gwyar'', "son of Gwyar". Gwyar appears to be his mother instead of father, [[{{UsefulNotes/Patronymic}} as was usual]], since she appears as Arthur's sister in genealogies. Some Welsh renditions of later Arthurian accounts put her name in place of ''Anna'' (better known as Morgause) and Gwalchmai instead of Gawain. Nothing is known of Gwalchmai's father, outside those aforementioned renditions that copy-paste and translate Gawain's father Lot as ''Lleu''.
* ThePowerOfTheSun: Some versions of the legends have him gain strength as the sun rises in the sky and lose it when it sets, whether as a function of his magic sword or of his being an Orkney.
* SpellMyNameWithAnS: Alternatively spelled Gawaine, Gawan, Gauvain, Gavan, Walwain, Walgan... etc.
* YouKilledMyFather: The cause of his feud with Lancelot that brings down the Round Table. His brothers Gaheris and Gareth are accidentally killed by Lancelot while unarmed. Notably when Lancelot earlier killed Agravaine Gawain wasn't so unhappy as he felt Agravaine brought this on himself through his spite, it's the deaths of his innocent brothers which spurs him into anger.

[[folder: Agravaine]]
* AdaptationalHeroism: ''Film/FirstKnight'' depicts him as a hero. On the other hand...
* AdaptationalVillainy: It seems he only starts being depicted a villain in the Vulgate and later tales.
* {{Jerkass}}: Nasty like Mordred but much more apparently so. Exposes Guinevere and Lancelot's affair.
* JerkassHasAPoint: He is not a nice guy, but he does make a valid point that a Knight of the Round Table should ''not'' be having an affair with the king's wife.
* PrettyBoy: Apparently his face is one of his only good features.
* TheRedBaron: "Agravaine the Arrogant/Proud"
* SpellMyNameWithAnS: Aggravain, Agrafrayn, Agravan, Agravano, Agreuein, Egrefayn, Engrevain(s), Gefferen, Geffreyn, Griffayn.
* TokenEvilTeammate: Had a reputation for malice and enviousness even before teaming up with Mordred. Still a respected member of the Table, who did the odd good deed or two.

[[folder: Gareth]]
* {{Bishonen}}: He was mockingly nicknamed "Beaumains" or "Fair Hands" by Sir Kay when he first came to Camelot disguised as a kitchen boy. He is often described as fair.
* LukeIAmYourFather: He's Gawain's brother.
* NiceGuy: The nicest and most innocent of the Orkney brothers, as even Gawain could be vengeful. Took no part in Lamorak's murder.
* SailorEarth: Possibly as late as 1470, as there's speculation that he was Malory's original creation.

[[folder: Gaheris]]
* DisproportionateRetribution: Seems to be his stock in trade. Killed a knight for saying Lancelot was better than Gawaine, beheaded his mother Morgause for the horrible crime of sleeping with the son of the guy who killed his father and later teamed up with his brothers to brutally murder said son. It goes both ways, though. He once arranged for a peasant to be given a fine horse after accidentally getting his donkey killed. Also see "MoralDissonance" below.
* DistinctiveAppearances: Apparently his right arm was noticeably longer than his left.
* EasilyForgiven: Apart from what seems to have been a temporary banishment, Arthur and the other Orkney brothers seem to be pretty accepting of his murder of Morgause, at least in Malory. As mentioned below, some other stories have him hiding the truth.
* {{Frameup}}: Some versions of the story have him pinning Morgause's death on Lamorak.
* {{Hypocrite}}: Rebuked Gawaine after he accidentally beheaded a lady who'd leapt in front of his stroke to protect her husband. Later quite deliberately beheaded ''his own mother'' for an even worse reason.
* MoralDissonance: Once came upon four pavilions. After helping himself to the food in one of them, he (chastely) bedded down in the fourth with a sleeping lady, not noticing her husband on the other side. Upon waking to see the furious husband yanking his wife out of bed by the hair, he lopped the guy's head off. Not ''too'' horrible so far, right? Well, then he demanded she love no one else but him and forced her to travel with him, killing three of her brothers and severely wounding the fourth when they tried to rescue her. Eventually she managed to get away from him by joining a convent.
* SelfMadeOrphan: In a rage he kills Morgause, his mother, when he finds her sleeping with Lamorak.

[[folder: Percival]]
* TheAce: Was called "The Best Knight in the World."
* {{Bishounen}}: He is the youngest of the knights, and the most feminine looking, as he was raised by his mother and never knew of men.
* ChasteHero: In later versions.
* CelibateHero: In some versions, and in most versions of the Grail Quest his hardest test is resisting a beautiful enchantress.
* CoolSword: In one set of stories gets a sword that can cut through anything and will never break... [[BlessedWithSuck except in the toughest battle of his life]].
* CuriosityIsACrapshoot: As a guest of the Fisher King, he saw a strange procession of people carrying magnificent objects, including a beautiful grail and a bleeding lance. Although dying of curiosity, he had always been told by his mother that it was rude to speak too much and so kept his mouth shut. Shortly after his return to Camelot, a loathly lady showed up at court and [[WhatTheHellHero called him out]], saying that if he'd only asked whom the grail served and why the lance bled, the Fisher King would have been cured of his [[WoundThatWillnotHeal wounds]]. In the Welsh version, Peredur son of Efrog, it’s his cousin’s decapitated head carried out on a dish instead of the Grail.
* DavidVersusGoliath: Pretty much literally in some versions. When he first comes to Camelot, he's just a young guy armed with some javelins or darts and no armor to speak of and takes down a huge and powerful knight that the knights of Camelot were afraid to fight.
* {{Determinator}}: In all versions is this.
* GoodIsDumb: Well, Good Is Badly-Educated, anyway. His mother deliberately raised him in isolation without teaching him about knighthood or civilization, in the hopes that he wouldn't turn out like his dead father and brothers. [[InTheBlood It didn't take.]]
* HeterosexualLifePartners: In some stories with Gawain, who is his cousin. In one legend he even chooses to share a curse Gawain brought upon himself; his willingness to sacrifice saves Gawain's life by splitting the curse in half and they each only get badly wounded.
* IdiotHero: In most stories, he's this in his younger days. Sometimes he grows out of it and into MessianicArchetype, sometimes he doesn't.
* ItsPersonal: Cai/Kay kicks a dwarf and his she-dwarfin in Peredur’s presence. There were 2 dwarves at Arthur’s court for a whole year, receiving Arthur’s hospitality, yet they never spoke to anyone. Then Peredur shows up to Arthur’s court for the first time, wanting to be a knight, and the dwarves immediately greet and praise Peredur. Cai is angered that the dwarves have been mute for a year in (their host,) Arthur’s presence, yet Peredur is who they shower with praise, so he strikes the dwarf and kicks the she-dwarf. Peredur leaves Arthur’s court, determined to avenge the insult Cai did to the dwarves. Peredur makes a name for himself, and tells all his defeated foes to go to Arthur’s court and tell of how he won’t return until he gets revenge on Cai. So the whole court yells at Cai for driving away such a fine lad. Peredur refuses to return unless he avenges that insult, which he does by breaking Cai’s arm and collarbone.
* KidAppealCharacter: A medieval version.
* LoveAtFirstSight: In Peredur son of Efrog, the Welsh version of Perceval, he certainly falls in love with women frequently. When he met Angharad Law Eurog, when she rejects him, he swears not to speak a single word to a Christian ever again until she says that he is the man she loves best. He kept it up so long he was called the Mute Knight. Eventually she spoke to him again, so he never broke his promise.
* MasterSwordsman: In some stories he's the best swordsman among the knights.
* NoSocialSkills: After the death of his father and brothers, Percival's mother takes him to the Northern forests (either the North of Britain or North of Wales) where she raises him ignorant to the ways of men until the age of fifteen.
* OopNorth: In the Welsh tradition, Peredur son of Efrog comes from the North of Britain (the Old North), or at least his father did. His father Efrog was the founder of York.
* PowerTrio: With Galahad and Bors.
* RoyalsWhoActuallyDoSomething: He's generally depicted as being of noble birth, with some authors making him another of King Pellinore's many, many children.
* SpellMyNameWithAnS: Alternatively spelled Perceval, Percivale, Parzival, or Parsifal.
** His name becomes Peredur in a tale collected in the Welsh ''Mabinogion'' that corresponds to the French ''Perceval'' by Chretien de Troyes, but it's debated which is derivative of the other. Peredur is attested elsewhere as a name while Chretien invented Perceval, so scholars disagree about which author did the renaming.
* TookALevelInBadass: Took several between his first visit to Camelot and his unhorsing of Kay. The Welsh version has him thrust his spear under Cai’s jawbone, and hurl him far off into the distance, with his fall breaking his collarbone. Even Arthur temporarily feared for Cai’s health.
* WeirdnessCensor: Peredur doesn’t find anything strange enough to ask about it, even when a decapitated head is carried out on a salver, along with a bleeding lance. That decapitated head turns out to be his cousin’s.
* WideEyedIdealist: Usually.

[[folder: Geraint/Erec]]
* CompositeCharacter: There was a Geraint son of Erbin mentioned in the early tales. Then, in the Mabinogion, he is used in one of the three romances. The romances usually parallel a French romance. Perceval and Peredur, Yvain and Owain. But instead of “Erec and Enide,” we get “Geraint and Enid.” Originally Erec was the son of King Lac, and most likely a Breton, and his adventures likely took place in Brittany. Geraint is the son of Erbin, he is Cornish, and his adventures take place in the southwestern part of Britain (Cornwall, Domnonia, Somerset, etc.) Erec holds land in and around Brittany, Geraint holds land in and around Cornwall.
** Geraint himself is a combination of several people: Gerontius (5th century British general), Geraint (6th century), Geruntius king of Domnonia/Devon (8th century), the Cornish saint Gerent, and Gerennius king of Cornwall.
* CourtlyLove: While most romances involve extramarital relationships, Geraint/Erec marries Enid(e) early on.
* DecompositeCharacter: While Geraint and Erec developed into separate characters, they easily could’ve been the same character once. Geraint was known in Brittany as Guerec, the leader that gave his name to Bro Weroc (territory around Vannes). The French “Erec” likely came from the Breton “Guerec,” and both are associated with Vannes.
* PlotIncitingInfidelity: After Geraint [[MistakenForCheating believes that his wife Enid is in love with another man,]] he and Enid go out on a quest into parts unknown. After a series of mishaps, the couple eventually reconciled and is reunited with Arthur’s court (Arthur and his men went searching for him) and also leads to his encounter with Owain.
* YourCheatingHeart: Geraint accuses his wife Enid of this in “Geraint son of Erbin.” She was crying over him and talking about how she brought dishonor to him. [[MistakenForCheating But Enid was only upset because Geraint had given up being a knight to be with her.]]

[[folder: Galahad]]
* TheAce: [[UpToEleven Even better than his dad]] Lancelot.
* AscendToAHigherPlaneOfExistence: He encounters Joseph of Arimathea while in Sarras, and feels such religious ecstasy that he asks to die on the spot. Angels then proceed to yank him up into Heaven without any actual dying involved.
* ChasteHero: Well, what do you expect from the purest of Arthur's knights?
* ChildByRape: Lancelot was tricked into sleeping with Galahad's mother via magical disguise.
* TheChosenOne: For the Grail quest in the later versions. In the earlier versions that he didn’t appear in, usually Perceval was the one that found the Grail, although Diu Crône has Gawain find the Grail.
* CoolSword: First wielded Sir Balin's Sword and later King David's sword, both of which which only [[TheChosenOne he]] could draw safely. The former wounded anyone else who tried, the latter invited actual divine retribution.
* CurbStompBattle: His specialty is handing out these.
* HeroicBastard: Even more heroic than his father Lancelot.
* IncorruptiblePurePureness: So pure that he was the only knight in the world worthy of the Holy Grail, and later basically just walks into Heaven.
* NamesTheSame: In-universe. "Galahad" was Lancelot's birth name. Another knight’s name, Galehaut or Gallehault, is often mistaken for a version of Galahad because Gallehault is much more obscure.
%%* PowerTrio: With Percival and Bors.%%ZCE
* RoyalsWhoActuallyDoSomething: Lancelot is technically a king, and Galahad later briefly rules the mystical realm of Sarras alongside Percival and Bors.
* SpellMyNameWithAnS: In Old French works his name is Galaad. This is thought to derive from Gilead in the Bible since it was spelled that way in the Latin Vulgate.

[[folder: Bors]]
* OvershadowedByAwesome: Percival and Galahad are the most-remembered Grail Knights. Bors, if he's remembered at all, is [[Film/MontyPythonAndTheHolyGrail that guy who the Killer Rabbit got to first]].
* PowerTrio: With Percival and Galahad
%%* TheSmartGuy
* SpellMyNameWithAnS: His name is spelled Bors in some sources and Bohort in others.
* UndeadAuthor: He serves to avert this problem. After the Grail quest is complete, Galahad ascended to heaven and Percival went off to be a monk. Bors was the only one to return to Arthur's court to tell the tale.

[[folder: Kay]]
* TheBigGuy: Known as "Kay the tall" and "the long man" in the Welsh legends, where he also has the power to [[SizeShifting grow to giant size]].
* BoisterousBruiser: Kay is almost always some sort of braggart; a good exception being Creator/JohnBoorman's ''Film/{{Excalibur}}''. But he’s still called gwyn (fair/beloved), at least in Welsh.
* ButtMonkey: In later versions where he merely exists to get beaten up.
* CatchPhrase: “By the hand of my friend,” with singular hand referencing the fact the Bedwyr (Bedivere) is one-handed.
* CoolSword: In the Welsh tales, no one can heal wounds dealt by Kay's sword, either because the sword is magic or the patient is too dead.
* DemotedToExtra: His role in later stories is severely reduced.
* {{Determinator}}: In “How Culhwch Won Olwen”, after a year of Arthur’s messengers searching for any details of Olwen and returning with none, Cai tells Culhwch that he and Arthur will search for Olwen, that neither Culhwch nor any of Arthur’s knights had ever met, until Culhwch admits she doesn’t exist or Olwen is found and united with Culhwch.
** But later Cai leaves Arthur’s group to find Olwen after Arthur sings a mocking song about him.
%%* HotBlooded: Like most other knights.%%ZCE
* FamilyThemeNaming: Possibly. In medieval Welsh his name is Cai or Cei, which is thought to derive from the Roman "Caius" or "Gaius", but also suggested to mean "way" or "path". His father Ector is called Cynyr in Welsh, which is thought to mean "way" or "path" also. This is supported by other theme-named {{UsefulNotes/patronymic}}s in medieval Welsh literature and cognates ''cai'' and ''conair'' in medieval Irish. If Cai son of Cynyr means something like "Path son of Way", it's similar to cases like Drem son of Dremhidydd "Sight son of Vision" and Nerth son of Cadarn "Strength son of Strong" from the story ''Culhwch and Olwen''.
* TheLancer: Not actually Lancelot, despite the name. In many ways, Kay is a heroic {{Foil}} to Arthur.
* MagicKnight: In his earliest incarnation from the Welsh tales.
* NeverLiveItDown: InUniverse. When Percival first showed up to Camelot, a woman who had previously sworn never to laugh unless she saw the man who would be the best knight in the world. When Percival arrives, she laughs. Kay is so insulted that he slaps her. Throughout the rest of the story, Percival's defeated foes keep coming back to Camelot to tell of how Percival was still trying to avenge her honor (basically to rub in how much of a douche Kay was).
** In the Welsh version, Peredur son of Efrog, Cai strikes a dwarf and then kicks a she-dwarf because they had pretended to be mute for the entire year they’d spent at the court, only to immediately talk to and greet and praise Peredur. Peredur defeats many other knights, and when they beg for mercy, he tells them to return to Arthur’s court to tell Arthur of his great service he has been doing as a vassal of Arthur. Arthur and his whole court, having heard of Peredur’s noble feats, berate Cai for driving away such a good lad as Peredur; Peredur refused to set foot in Arthur’s court unless he confronted “the tall man” (Cai/Kay) and avenged the insult to the dwarves.
* TheNicknamer: An example being Sir Gareth, who he dubs "Beaumains" after the former refuses to reveal his name.
* NumberTwo: Together with Bedwyr, since they're roughly equal in precedence, though his name always comes first--until they're DemotedToExtra and supplanted by Lancelot.
* PlayingWithFire: In the Welsh tales Kay can generate so much body heat that he can keep dry in rain, which provides kindling to Arthur men when they are at their coldest. He can also weather fire well.
* PowerTrio: With Arthur and Bedwyr in early versions.
* SizeShifter: One of his peculiar magic qualities in “How Culhwch Won Olwen.”
%%* SnarkKnight: More in the early stories.ZCE
* SpellMyNameWithAnS: Cai or Cei in Welsh.
* SuperNotDrowningSkills: Kay can hold his breath underwater for 9 days and nights in the Welsh material.
* TheFriendNobodyLikes: Gwalchmai, Owain, Arthur, and eventually Arthur’s whole court scold him for his behavior in “Peredur son of Efrog.” Gwenhywfar casually says that Cai should be hanged for insulting such a man as Owain in “The Lady of the Well.” Peredur strongly despises Cai to the point where he refuses to set foot in Arthur’s court ever again until he has confronted him and avenged Cai’s insult to the dwarves, and Cai took such offense to the satirical englyn Arthur sang in “How Culhwch Won Olwen” that he refuses to have anything to do with Arthur. But Arthur still deeply cares for Cai, and it’s assumed that the other knights do as well.
* TrueCompanions: With Arthur. They were raised as brothers before Arthur found out his true heritage, and Kay is invariably loyal and stalwart even as he became more boorish as the stories developed. He’s said to be one of the most loyal members of the Court.
* TheWorfEffect: He seems to have a habit of getting the crap beat out of him to show how much better the new knight du jour is, although some theorise that this is a case of BadassDecay, and that his original role was to be the one who tested new knights' combat skills (which would imply a high degree of skill on his part, since he'd need to not kill or maim his opponent while avoiding the same fate at their hands).

[[folder: Bedivere]]
* BashBrothers: Often paired with Kay in the oldest Welsh material.
* BattleButler: Arthur's cup-bearer in later versions. Sometimes has a brother, Lucan, who is Arthur's designated butler.
* CompositeCharacter[=/=]{{Expy}}: In several modern Arthurian retellings favoring the older traditions as opposed to Malory et al, Lancelot does not appear. Instead, Bedivere is often made Guinevere's lover. It helps that many of Lancelot's usual traits apply to Bedivere also. This was first done in Creator/RosemarySutcliff's ''Literature/SwordAtSunset'', and a number of other works have followed suit, such as Creator/MaryStewart's ''[[Literature/TheMerlinTrilogy Merlin trilogy]]'', [[Literature/TheSandReckoner Gillian Bradshaw]]'s ''In Winter's Shadow'', Joan Wolf's ''The Road to Avalon'' and [[Literature/MortalEngines Philip Reeve]]'s ''Here Lies Arthur''.
** Bedivere takes the role of Sir Griflet (ultimately based on the Welsh Gilfaethwy) of throwing Arthur’s sword back.
* DemotedToExtra: Just like Kay, his role was much reduced as the mythos grew and developed.
* HandicappedBadass: In the oldest Welsh material, he is one-handed. He was also a LightningBruiser with a four pronged spear.
* HeterosexualLifePartners: with Kay.
* {{Hunk}}: In Welsh material, said to be one of the most handsome men in Britain, next to Arthur himself and only one other man.
* NumberTwo: Together with Kay, since they're roughly equal in precedence, though his name always comes second--until they're both DemotedToExtra and supplanted by Lancelot.
* PowerTrio: With Arthur and Kay in early versions.
* SoleSurvivor: Thanks to Malory, he may be best known today as the one knight of the Round Table who survives Arthur's last battle, and who throws Excalibur back into a lake, even though he did not survive that long in the earlier versions (the Welsh tradition has different survivors, though it doesn't mention his death but rather his grave; Geoffrey has him and Kay die fighting the Romans). Sometimes it’s a former squire named Sir Griflet (or Girflet) that throws back the sword. Bedivere's brother Lucan also lives long enough to help carry the mortally wounded Arthur, but the effort opens his own wounds and he dies first. Modern writers tend to keep Bedivere as the last survivor especially if he's also one of Arthur's oldest companions, for DramaticIrony.
* SpellMyNameWithAnS: Bedevere, Bedwyr in Welsh.

[[folder: Mordred]]
* AntagonisticOffspring: To Arthur, in the versions where he's his son and not just his nephew. One of the alternate names for the trope is ArthurAndMordred.
* AwfulTruth: Learning the truth about his conception and future were enough to prompt a ''hard'' FaceHeelTurn.
* BastardBastard: Following his FaceHeelTurn, whatever noble qualities he once had flew straight out the window.
* CainAndAbel: Some stories have him being rescued from the May Day massacre by Sir Sagramore's family and raised for several years as his stepbrother. That doesn't stop him from killing Sagramore at Camlann.
* ChildByRape: Some versions of the tale have Morgause using magic to get Arthur to sleep with her. Some have Arthur raping her, particularly modern versions. Originally it seems to have been a perfectly consensual relationship, albeit one where neither was aware of their relation.
* CoolSword: Swiped Clarent, Arthur's ceremonial sword, and eventually killed him with it.
* EvilNephew: In most versions of the story, first from Geoffrey, Arthur is his uncle.
* FaceHeelTurn: Actually seemed quite promising during the first two years of his knighthood, earning praise from Lancelot himself. He was once popular with the ladies, at least in the Welsh material, at one time.
* FakeKing: Yes and no. Arthur leaves him in charge of the kingdom when he goes to fight Lancelot in France, and he does officially have himself declared king, but he isn't the rightful ruler. In some versions (often Scottish) Mordred is viewed as a legitimate ruler, or having the right to be, in the versions where Mordred/Medrawd is the son of Arthur’s sister and her husband, and thus born legitimate. Arthur himself falls into some sketchy territory about his own legitimacy (concerning his birth.)
* FallenHero: Both in the literal and meta sense. He's usually depicted as at least competent and loyal to Arthur until he finds out who his father is. However, the original legends take this even further, implying he's Arthur's peer and ally, biologically his nephew and legally his foster son. The original reason for their inevitable confrontation is supposedly tied into a spat between Gwenhwyfar and her sister Gwenhwyfach.
* GenocideBackfire: He was one of the children in the May Day massacre, where King Arthur had all the children born on May Day sent out on a shoddily-built boat to die after receiving a prophecy that a child born on May Day would kill him. Mordred, of course, survived, grew up hating Arthur and eventually killed him.
* HeroKiller: Killed Lamorak, Dinadan, Sagramore, Ywain, and of course King Arthur himself.
* HeroicBSOD: Being told that you're the bastard son of the king and his half-sister, prophesied to destroy the kingdom and do more harm in your lifetime than all your ancestors did good kind of does that to you. He came out of it...uh, pretty badly, actually.
* IHaveYouNowMyPretty: With Guinevere after the takes over England. Averted in versions of the story where she joins his rebellion and hooks up with him willingly, bearing him two sons.
* ImAHumanitarian: In one version of the story where Guinevere joins his rebellion, Lancelot kills her and locks Mordred in her tomb. He eventually eats her out of desperation, and then ultimately starves to death anyway.
* MutualKill: He and Arthur.
* ShootTheMessenger: Murdered the prophetic priest who revealed the truth about his life to him. Lancelot was pissed...[[ItsAllAboutMe because the priest was going to reveal]] ''[[ItsAllAboutMe his]]'' [[ItsAllAboutMe future next.]]
* SpellMyNameWithAnS: Modred, Medraut, Medrawd, Medrod, etc. The form "Mordred" was probably irresistible to writers because it's similar to Latin ''mors'' or French ''mort'', meaning [[NamesToRunAwayFromReallyFast Death]].
* TokenEvilTeammate: In spite of the severe downturn his personality took, he remained a member of the Round Table in good standing. But he was said to have been kind and chivalrous back then.
* TragicVillain: Particularly in modern interpretations. Still, it's not as if he ''asked'' Morgause and Arthur to sleep together.
* VillainWithGoodPublicity: When he takes over Britain, he's popular with the people for bringing peace while Arthur's reign was more or less constant battles.

[[folder: Palomides]]
* GreenEyedMonster: Most of the reason he alternates between seeing Tristram as a brother-in-arms and wanting to gut him is because they are both in love with La Beale Isoud. [[SpellMyNameWithAnS Er, Isolde? Yseult? Whatever.]]
* HumansAreWhite: Not the only ex-Saracen knight (his brothers Segwarides and Safir joined, too, and Sir Morien joined later), but certainly the most prominent by far.
* KickTheDog: On the receiving end of one. After she convinces Tristram to spare his life following on of their clashes, Isolde makes Palomides deliver a message to Guinevere stating that there were but four true lovers within the land: Guinevere and Lancelot and Tristram and Isolde. ''Ouch.''
* TheQuest: Took over Pellinore's hunt of the Questing Beast.
* RoyalsWhoActuallyDoSomething: Son of the Saracen king Esclabor.
* SpellMyNameWithAnS: Palamedes.
* {{Tsundere}}: A friendly version toward Tristram.

[[folder: Segwarides]]
* BrosBeforeHoes: Forgives Tristram, saying that he "will never hate a noble knight for a light lady". The fact that they were trapped on the dangerous Isle of Servage at the time probably helped.
* CompositeCharacter: There was a Segwarides mentioned before this one, but as there's nothing differentiating them, most people treat them as the same character.
* RoyalsWhoActuallyDoSomething: Son of the Saracen king Esclabor, also becomes Lord of the Isle of Servage after Tristram beats Nabon le Noire.
* SpellMyNameWithAnS: Segurades.
* YourCheatingHeart: His wife's. She had an affair with Tristram, but later reconciled with her husband.

[[folder: Safir]]
* MistakenIdentity: Fought Palomides disguised as Ector de Maris, without recognizing him.
* RoyalsWhoActuallyDoSomething: Son of the Saracen king Esclabor.
* SpellMyNameWithAnS: Safere.

[[folder: Marrok]]
* {{Expy}}: His story's pretty much a straight ripoff of the earlier ''Literature/{{Bisclavret}}'' by Marie de France.
* WolfMan: Yes, seriously! He automatically changes into a wolf for a few days every month [[OurWerewolvesAreDifferent and if he can't change back into his clothes after that, he stays that way indefinitely.]]
* YourCheatingHeart: Not his, but his wife's. She hid his clothes so she could run off with her lover. Wolf-Marrok tore off her nose, and King Arthur tortured a confession out of her. She then got exiled with the lover and [[LamarckWasRight had a bunch of noseless kids.]]

[[folder: Dagonet]]
* AdaptationalBadass: [[Film/KingArthur And how!]] Also counts as AscendedExtra.
* CrouchingMoronHiddenBadass: For all his flaws, he did manage to track down and kill the guy who kidnapped his wife, so there may be ''something'' there.
* TheJester: That's his job. Sometimes he even shows the insight one might expect from one of these characters.
* JokeCharacter: King Arthur's jester, knighted as a gag. Participates in a lot of pranks based around his lack of competence.
* KarmaHoudini: False Guinevere puts him in charge of the Royal Household, which he proceeds to bankrupt, and he kills the Royal Treasurer for taking him to task over it. No one seems to care.
* LovableCoward: So hilarious and good-natured that the other knights don't care how often he runs from battles.
* MilesGloriosus: Tried for this, constantly boasting and doing things like battering his shield so it looked like he'd been in a nasty fight, but no one was fooled.
* SpellMyNameWithAnS: Dagenet, Daguenes, Daguenet, Daguenez li Coars, Danguenes de Carlion.

[[folder: Dinadan]]
* BadassFamily: Son of Sir Breunor Senior, "The Good Knight Without Fear", brother to Sir Breunor le Noire aka "La Cote Mal Taile" and Sir Daniel.
* BewareTheSillyOnes: Funny as he can be, and as much as he hates getting into fights, he's as capable a fighter as the other knights, and acquits himself well in tournaments.
* BrutalHonesty: When traveling with a mysterious knight, he mocks the knight's incompetence. Upon learning said knight is King Mark traveling incognito, Dinadan lets loose with both barrels, calling him a cowardly murderer, and crappy king, to boot.
* CelibateHero: "God defend Me. For the joy of love is too brief; and the sorrow thereof, and what cometh thereof, dureth overlong"
* TheCharmer: Easily able to win people over and cheer them up. Just about every knight likes him.
* DeadpanSnarker: Depicted as among the wittiest of Arthur's knights in general, with modern adaptations tending to emphasize this particular trope.
* DisproportionateRetribution: Mordred and Agravaine killed him in part because of resentment over the incident below and [[NoodleIncident "because of Sir Lamorak"]]--given his personality, it's likely he made some remark regarding their treacherous assassination of said knight.
* TheGadfly: Occasionally took on this role in order to encourage his fellow knights.
* KnightInSourArmor: Could occasionally be this, as when he teamed up with Tristan and spent most of the time complaining about all the fights Tristram got him into, calling Tristram and Lancelot nuts for being {{Blood Knight}}s, and cursing the day he'd entered Tristram's company.
* NoGoodDeedGoesUnpunished: Saves Mordred and Agravaine from Breuse Sans Pitie, then gets murdered by them during the Grail Quest.
* OnlySaneMan: Stories tend to have him pointing out the flaws in society, mentioning how stupid is it to get into all these unnecessary battles over honor, or courtly love, or just because. Even in stories where he doesn't, he still prefers talking things out to dueling. [[BewareTheSillyOnes Not that he can't throw down if he needs to]].
* TheSmartGuy: Possessed a great deal of common sense, and is one of the few knights who can identify other knights by their faces as well as their coats of arms. Given the sheer number of duels caused by mistaken identities in these stories, this makes him pretty useful to have around.
* UngratefulBastard:
** Not him, but after rescuing Mordred and Agravaine from Breuse Sans Pitie, Dalan, the guy ''they'd'' been trying to rescue claims that Dinadan killed his father, so he attacks him. [[ShaggyDogStory Dinadan knocks Dalan off his horse and breaks his neck]]. Also, Mordred and Agravaine eventually kill him.
* WarriorPoet: Wrote a mocking ballad about King Mark that was apparently downright ''savage''. If Tristram's reaction to reading it (Roughly: "Ha! Oh, that Dinadan!") is any indication, he did this sort of thing a ''lot''.
* WittyBanter: Many of his conversations consist of this.

[[folder: Ywain]]
* AndroclesLion: Probably what he's best known for.
* BloodKnight: Settled down for a bit after marrying Laudine, but Gawain showed up and tempted him back into adventure. Laudine agreed to let him go WalkingTheEarth, but only if he would return to her after one year. She eventually had to send someone to hunt Ywain down and tell him [[GetOut not to bother coming back.]]
* DisproportionateRetribution: Esclados the Red, guardian of a supernatural storm-causing fountain, (non-fatally) fought Ywain's cousin Calogrenant after he came upon said fountain and caused a dangerous tempest. Ywain, upon hearing of this, ''hunts him down, kills him, and takes his widow for himself''.
* DrivenToMadness: By his breakup with Laudine.
* RingOfPower: Laudine gives him one to protect him when he goes off adventuring, and takes it back when he breaks his promise.
* RoyalsWhoActuallyDoSomething: Son of King Uriens and (sometimes) Morgan Le Fay.
* SecondLove: For Esclados' widow Laudine. [[AndNowYouMustMarryMe Eventually.]]
* SpellMyNameWithAnS: Yvain, Ewaine. Based on the Welsh form Owain.
* UndyingLoyalty: Earned a loyal Lion companion for saving it from a dragon.
* YouKilledMyFather: Esclados beat up his cousin. He was not happy about that.

[[folder: Aglovale]]
A son of King Pellinore and one of the brothers of the hero Percival.
* BackForTheDead: Spent several years ruling alongside Morien's mother before returning to Arthur's court-- ''just'' in time to be killed by Lancelot during his rescue of Guinevere.
* BigBrotherMentor: Serves as this for Percival in some tales.
* ThePromise: While seeking Lancelot, he hooks up with a Moorish princess, and swears to come back and marry her when his mission is over. ''Fourteen'' years later, his [[HeroicBastard son]] Morien shows up to hold him to it.
* RoyalsWhoActuallyDoSomething: Son of Pellinore, also becomes king of an Arabian land after fulfilling ThePromise.
* SpellMyNameWithAnS: Agglovale, Agloval, Agravale, Engloval(e).
* WifeBasherBasher: One work of Arthurian lore mentions that Aglovale fought and humbled a misogynistic knight for abusing his lover.

[[folder: Alexander the Orphan]]
Appears in Palamedes, Prose Tristan, Prophecies of Merlin, and ''Literature/LeMorteDarthur''.
* CelibateHero: He rejected Morgan Le Fay's advances. Later subverted when he married Alice the Fair Pilgrim.
* KilledOffForReal: The details vary as to whether he was killed by a minor knight or an assassin hired by King Mark, but regardless he didn't live to either go on the Grail quest nor the end of Arthur's reign.
* {{Revenge}}: Against [[EvilUncle Mark]] for killing Prince Bodwyne, his father and Mark's younger brother.
* TragicKeepsake: The blood-soaked shirt his father wore when he was killed.

[[folder: Tristan]]
While there are a few mentions of him in early Celtic Arthurian material, he is best defined by [[Literature/TristanAndIseult his tragic romance with the lady Iseult]] -- which might have started as a separate story that later authors incorporated into the wider Arthurian mythos.
* DeathByDespair: He dies of poison, but the false belief that Iseult has abandoned him is what makes him succumb to the poison before help arrives.
* GuileHero: Often uses guile and trickery to keep his affair secret.
* ICallItVera: His bow is named Fail-Not.
* ReplacementGoldfish: Since he can't be together with Iseult, [[OneSteveLimit he marries another woman who is also named Iseult.]] [[DownerEnding This manages to go even worse than you'd expect.]]
* SpellMyNameWithAnS: Also often known as Tristram. The Welsh equivalent is Drystan,
* StarCrossedLovers: His lover is married to his uncle and king, and he can only [[DoubleEntendre "meet"]] her in secret until they both die.
* TogetherInDeath: Tristan and his lover are buried side by side, and a honeysuckle springs from Iseult's grave and twirls around a hazel tree that grows from Tristan's grave. [[DependingOnTheWriter Or maybe it's a briar that twirls around a rose.]] [[DownerEnding Or maybe they're just plain dead.]]

[[folder: Lamorak]]
* DisproportionateRetribution: Morgan le Fay, seeking to expose Guinevere and Lancelot's affair sent a magical drinking horn to King Arthur's court that no lady who was cuckolding her husband could drink from without spilling. Lamorak, out of resentment from the DontYouDarePityMe incident below, intercepted the messenger and had it sent to King Mark's court instead. (How'd he know what it did? Never mind that.) Isoud and Tristram's affair was very nearly exposed as a result, and if Tristram wasn't invested in their rivalry ''before''...
* DontYouDarePityMe: After the second time Lamorak unseated thirty knights in a row, King Mark ordered Tristram to fight him. Seeing how exhausted he was, Tristram refused to take the fight beyond unseating Lamorak from his horse. This led Lamorak to feel slighted, and touched off a rivalry between them.
* FeudingFamilies: With the Orkney brothers (see Pellinore). Banging their mom didn't especially help things.
* HeterosexualLifePartners: With Lancelot and Palomides.
* HotBlooded: Famed for his fiery temper (once got into a fight over whether Morgause or Guinevere was prettier) and his great strength (unseated thirty knights in a row in jousts on two occasions).
* InTheBack: Died from being stabbed by Mordred, [[DependingOnTheWriter sometimes]] after a three-hour battle with the other Orkney brothers (save Gareth).
* LastSecondChance: After being on the run for a while from the Orkneys, he shows up at a tournament and meets Arthur in secret. Arthur, who had previously allowed the Orkneys to hunt Lamorak, has had time to repent of this hasty decision and offers him forgiveness and protection if he'd only accept a truce with the Orkneys. Lamorak doesn't trust them to obey Arthur, and besides, he wants to avenge Morgause and his father, so he declines. Bad idea.
* MayDecemberRomance: With Morgause. [[OffWithHisHead Briefly.]]
* MisplacedRetribution:
** He tells Gaheris that it wasn't Pellinore who killed Lot, but Balin Le Savage. It's unclear whether this is true, but Gaheris doesn't believe him.
** The Orkney brothers killed him to avenge Morgause. Well, except for Gareth, who was too kind-hearted to be vengeful, and Gaheris, [[{{Matricide}} who knew perfectly well that Lamorak wasn't responsible]], but attacked him anyway. Averted in stories where Gaheris owns up right away and they just kill Lamorak because of the feud.
* OneManArmy: After the circumstances of his death became known, people note that of ''course'' the Orkneys ambushed him, since he could easily have killed them all otherwise. It was still a three hour fight, which only ended because Mordred backstabbed him.
* OutOfFocus: Referred to as King Arthur's third-best knight (after Lancelot and Tristan), but barely shows up in the stories, and is almost unknown outside them.
* RevengeBeforeReason: As mentioned above, he refused an opportunity to resolve his feud with the Orkneys peacefully.
* RoyalsWhoActuallyDoSomething: Son of King Pellinore.
* WhatTheHellHero: Gives Gaheris an extremely well-deserved one after he cuts off his mother's head.
* YouKilledMyFather: To the Orkneys.

[[folder: Tor]]
* ChildByRape: Pellinore begot him on Vayshoure "half by force", which is a bit ambiguous.
* ChocolateBaby: Tall and handsome unlike his thirteen(!) half-brothers and alleged father, Aries.
* HeroicBastard: Begotten by King Pellinore on the wife of a cowherd before her marriage.
* TheQuietOne: "[...] For I have seen him proved, but he saith little and he doth much more".
* {{Retcon}}: Originally the son of King Aries, later retconned into the illegitimate son of Pellinore. Poor Aries got turned into a cowherd!
* RoyalsWhoActuallyDoSomething: (Illegitimate) son of Pellinore, or legitimate son of King Aries.

[[folder: Ironside]]
* ColorCodedForYourConvenience: Red shield, red armor, red weapons, and red harness.
* EasilyForgiven: Sure, he murdered forty knights, hanging them from a tree so they wouldn't be allowed to die in honorable combat, but he was doing it to fulfill his promise to a lady, so it's fine.
* TheRedBaron: "The Red Knight of the Red Launds".
* SuperStrength: Like Gawain, he grows more powerful as the day passes, until at noon he has the strength of seven men. Unlike Gawain, it's not mentioned if this is tied to the sun itself.

[[folder: Morien]]
* AmazingTechnicolorPopulation: His skin is described as so black ("blacker than soot or pitch") that his teeth stand out sharply in contrast.
* AsskickingEqualsAuthority: After he brings Aglovale back to his kingdom, a group of nobles refuse them entry, seeking to keep his heritage for themselves. Morien proceeds to [[OneManArmy slaughter all fifteen of them]], and the other nobles fall into line.
* BadassBoast: "For what do ye take me? Am I a lesser or a weaker man than either of ye that Sir Gawain must needs ride with me? I will not have it so. There is no knight so bold but I dare well withstand him. I know well what is unfitting. Now say whither ye will betake ye, and send me what road ye will; I will dare the venture, be it never so perilous. By my knighthood, and by all who follow Christendom, I shall adventure alone, and take that which may chance."
* TheBigGuy: Taller than any other knight, and described as practically superhuman in strength and fighting skill.
* ButNotTooBlack: Inverted. In spite of having a white father and hailing from the Middle East rather than DarkestAfrica, Morien is as black as pitch. No, ''[[AmazingTechnicolorPopulation literally]]'' black as pitch.
* ColorCodedForYourConvenience: Black Moorish armor and black shield.
* CoolHorse: The text points this out several times. Coming from Moorish lands, it's not surprising.
* DisappearedDad: Though in Aglovale's defense, he probably didn't know his lover was pregnant.
* {{Expy}}: Of Feirefiz from ''Parzival'', though a rather loose one.
* HeroicBastard: Son of Aglovale and a Moorish princess (later queen).
* KidHero: His adventure takes place when he's about fourteen.
* OneManArmy: Takes on a small army of armed, armored fighters to rescue Gawain, killing them by twos and threes and never getting a scratch.
* PositiveDiscrimination: The whole story is basically the "Morien is Better Than Everyone Show".
* RoyalsWhoActuallyDoSomething: Although he and his mother were disinherited upon his birth, until Aglovale marries her.
* ScaryBlackMan: One boatman practically freezes up and wets his pants upon seeing Morien. Sir Gariet basically says: "Hey, moron, do your job or ''he's'' not going to be the one who kills you."
* SpellMyNameWithAnS: Moriaen, Moriaan.
* TeensAreShort: Subverted. At fourteen, he's a good six inches taller than any of Arthur's knights.

[[folder: Lucan]]
* AlmightyJanitor: Averted. In spite of the name, as the Royal Butler, he was in charge of the Royal Household and Court, and was thus equal in rank to Kay the Seneschal, not a mere servant.
* BattleButler: Though his duties kept him from adventuring as much as others.
* CassandraTruth: Warns Arthur that personally attacking Mordred after the Battle of Camlann was over would be pointless (he'd already "[[PyrrhicVictory won]]" the battle) and dangerous (at least one prophetic dream had said so), but Arthur decides to go for it anyway. End result: One dead traitor, one dying king, and eventually [[CriticalExistenceFailure one dead Lucan]].
* CriticalExistenceFailure: Picking up the mortally-wounded Arthur opens up one of his wounds, and his guts spill out, killing him instantly.

[[folder: Sagramore]]
* TheBerserker: Slipped into a mad frenzy when he was fighting.
* CainAndAbel: Some stories have him raised for several years alongside Mordred as a stepbrother. Mordred still kills him at Camlann.
* CompositeCharacter: A 16th century Portuguese novel ''Triunfos de Sagramor'' combines him with the legendary king Constantine III. "Sagramore Constantino" is Arthur's son-in-law and heir, who forms a new Round Table.
* FightingYourFriend: A fragmentary story finds him forced into a fight with Gawain.
* HotBlooded: One of his epithets is "The Impetuous" or "The Hotheaded".
* IllBoy: Suffered from nasty epileptic fits, and his berserker rages left him [[PostVictoryCollapse exhausted, suffering from migraines, and starving]]. Sir Kay, nice guy that he is, nicknamed him "Morte Jeune" ("Dead youth") as a result.
* RoyalsWhoActuallyDoSomething: Son of the King of Hungary and the daughter of the Eastern Roman Emperor, heir to the throne of Constantinople and when his father dies, his mother remarries ''another'' king.
* SpellMyNameWithAnS: Sagremor, Saigremor.
* TheWorfEffect: Like Sir Kay, he had a reputation as a fierce warrior, but tended to get kicked around to show off other peoples' skills.

[[folder: Pelleas]]
* DamnedByFaintPraise: After Gawain leads her to believe he killed Pelleas, Ettard says it's a shame because he was a good knight...and that she had hated him more than anyone because he wouldn't leave her alone.
* DeathByDespair: After discovering that Gawain had slept with Ettard in spite of agreeing to be a go-between between them, he went home, fell into bed and said that he refused to get out until he died, telling his servants to give his heart in between two silver dishes to Ettard. Since he showed up later, he was probably just being a DramaQueen.
* DoggedNiceGuy: Well, he saw ''himself'' this way, and some versions of the story ''do'' have Ettard eventually reciprocating his advances.
* FakingTheDead: Gawain helped him cook up a plan where Gawain would claim to have killed him and take his armor to Ettard, whereupon...[[MissingStepsPlan it's not really clear]]. The plan fell apart when Gawain decided he wanted a piece of that sweet, sweet Ettard action for himself, and got it.
* ISurrenderSuckers: A very weird, um, inversion? Every single day, Ettard would send ten knights to try and drive him away. Pelleas would thrash them, then force them to "capture" him and take him into Ettard's presence, just long enough for her to stick him in a cell overnight and kick him out in the morning.
* OneManArmy: Beat sixty knights in a tournament in order to give Ettard the jousting crown as a gesture of love (she laughed in his face and told him to step off), and regularly beat up ten knights single-handedly.
* SecondLove: With Nimue, and Nimue's second love after Merlin.
* SelfProclaimedLoveInterest: To Ettard, who wasn't remotely interested.
* SingleTargetSexuality: Malory mentions that there were much more attractive women at the tournament, who would have happily accepted Pelleas' crown and attentions, but he only had eyes for Ettard. Nimue fixed that, and how.
* StalkerWithACrush: Parked himself on Ettard's lands and refused to go away, no matter how often he was rebuffed.
* StayInTheKitchen: Nimue apparently kept him on a pretty tight leash, since he only shows up a couple of times after they get together. It's explicitly mentioned that this keeps him from getting killed like almost every other knight in the end, however.
* UnrequitedLoveSwitcheroo: He eventually caught Nimue's eye and she cast a spell to turn all his love for Ettard into hate and all Ettard's hate for him into love. He ended up with Nimue, and Ettard suffered a DeathByDespair. All's well that ends...never mind.
* WhatTheHellHero: After discovering Gawain and Ettard in bed together, he laid his sword across their necks while they were asleep and went back home.
!Evil Knights

[[folder: Accalon]]
Appears in the Post-Vulgate Merlin and Malory's ''Literature/LeMorteDarthur''.
* KilledOffForReal: By Arthur.
* SpellMyNameWithAnS: Accolon.
* UnwittingPawn: Of his lover, Morgan Le Fay, in an attempt to have her half-brother King Arthur killed.
* WorthyOpponent: Arthur considered him this, and Sir Accalon thought the same in turn, when the former apologized for having mortally wounded the latter. Arthur had the Gaulish Knight buried with honors at St. Stephen's Church in Camelot. (At least in versions of the story that don't have Arthur sending his body back to Morgan.)

[[folder: Breuse Sans Pitie]]
* CarFu: Rather, Horse Fu. Liked to ride over unhorsed knights, and actually ran over Gawain ''twenty times'' in an effort to kill him.
* CombatPragmatist: No dirty trick is below him.
* ForTheEvulz: Apparently the closest thing to a motive he's got.
* JokerImmunity: One of Malory's most frequently used villains, always popping up somewhere to steal, rape, or murder. In a genre where the villain is usually dispatched very quickly, he never gets caught or killed; the best the heroes manage is to run him off for a while.
* WoundedGazelleGambit: When fleeing from a fight, he would often enlist aid from others by claiming that he was an innocent being pursued by Breuse Sans Pitie. (It was often hard to tell which knight was which with the armour.)

[[folder: The Brown Knight Without Pity]]
* DamselInDistress: Liked to kill knights and take their ladies back to his castle.
* HaremSeeker: Had a collection of about thirty damsels before Gareth killed him.
* OnlyKnownByTheirNickname: Probably not the same character as Breuse Sans Pitie, since he actually got killed.

[[folder: Garlon of Listineise]]
* BlackSheep: Descendant of Joseph of Arimathea and brother to King Pellam, the most worshipful man in the land and King Pellinore, one of Arthur's greatest allies. Sheep don't get much blacker than this.
* EvenEvilCanBeLoved: King Pellam loved him enough to try to avenge him.
* FamousAncestor: Joseph of Arimathea.
* ImpaledWithExtremePrejudice: Stabbed Sir Herlews le Berbeus with his lance so hard that it broke, and continued using it as a truncheon afterward. Sir Balin [[HoistByHisOwnPetard used said truncheon]] to return the favor.
* {{Invisibility}}: Somehow he had this power.
* MagicKnight: By implication.
* RoyalsWhoActuallyDoSomething: Brother of Kings Pellam and Pellinore.
* SerialKiller: Liked to go around murdering people while invisible, including two knights.
* UnwittingInstigatorOfDoom: In order to avenge him, King Pellam attacks Balin when he is a guest in his castle, forcing Balin to use the Spear of Destiny to protect himself, striking the Dolorous Stroke that destroys Pellam's castle and kingdom and renders Pellam crippled.
* WoundThatWillNotHeal: Somehow inflicted a wound on a gentleman's son that wouldn't heal unless he received Garlon's blood. Thanks, Balin!

[[folder: Meliagrant]]
* AllLoveIsUnrequited: For Guinevere.
* AttemptedRape: Fortunately Bagdemagus stopped him before he could do the deed.
* FaceHeelTurn: Once a knight of the Round Table, held in high enough regard by Arthur to have been gifted a castle.
* KnowWhenToFoldEm: Tried to surrender when it was clear how badly Lancelot had him outclassed in combat. Lancelot didn't oblige, although he did offer to take part of his armor off and tie his left hand behind his back. [[DiagonalCut It didn't help.]]
* LoveMakesYouEvil: Was considered "a good man of great might" until he finally snapped and kidnapped the queen.
* RoyalsWhoActuallyDoSomething: Son of King Bagdemagus.
* SpellMyNameWithAnS: Meliagrance, Meliagant, Maleagant, etc. Appears as "Malagant" in ''Film/FirstKnight''. Melwas in Celtic.
* TrapDoor: Used one in his castle to try and capture Lancelot instead of fighting him.
* UnknownRival: Barely a blip on Lancelot's radar until the aforementioned kidnapping.

[[folder: Nabon Le Noire]]
* CurbStompBattle: Handily killed every one of his opponents in the below-mentioned tournament, until Tristram showed up.
* EvenEvilHasLovedOnes: Held a tournament in honor of his newly-knighted son.
* HeroKiller: He slew several of Arthur's knights.
* InvulnerableHorses: Averted. Nabon often targeted his opponent's steed.
* OurGiantsAreBigger: "A great mighty giant."
* RoyalsWhoActuallyDoSomething: Rules the Isle of Servage.
* YouKillItYouBoughtIt: Tristram takes over the Isle of Servage after killing him, and gives it to Segwarides.

[[folder: Pinel Le Savage]]
* DirtyCoward: Tried to poison Gawain to avenge Lamorak, rather than face him in combat, laid low and let the Queen take the blame, then ran back to his country when Nimue revealed the truth.
* KarmaHoudini: Apparently never received punishment for his treachery.
* YouKilledMyFather: Gawain killed his cousin, which is why he tried to poison Gawain, though envy may have played a part as well.

!Fair Ladies

[[folder: Morgause]]
* AdaptationalVillainy: Modern writers tend to make her a scheming villainess, often by making her aware of her relationship with Arthur when she sleeps with him, or by combining her with Morgan Le Fay. Originally, she seems to have been a generous and friendly person. ''[[ReallyGetsAround Very]]'' friendly.
* BrotherSisterIncest: Though neither she nor Arthur were aware of it at the time.
* DecompositeCharacter: Some scholars suggest that she and Morgan Le Fay were the same character until some scribe made a translation error and accidentally split them into two separate characters.
* GrandmaWhatMassiveHotnessYouHave: After five sons and a number of daughters, she still had enough of it goin' on to bed Sir Lamorak, who was at ''least'' twenty years younger than her.
* HoneyTrap: Malory states that Lot sent her over to Arthur's court in this capacity.
* NamesToRunAwayFromReallyFast: In the older Welsh material, Arthur's sister is named Gwyar, which means "bloodshed".
* OutWithABang: Her son Gaheris, incensed at seeing her in bed with the son of Pellinore (who killed Lot, the Orkney brothers' father), lopped her head off.
* SpellMyNameWithAnS: Margawse, Morgawse, Margause, [[OddNameOut Bellicent...]]
** In Geoffrey of Monmouth, Arthur's sister is just called [[AerithAndBob Anna.]] (She does nothing, [[AscendedExtra later writers greatly expanded her role]].) Since Morgan is sometimes spelled Morgana this may have added to the confusion.
* UnholyMatrimony: In versions that play up her and Lot's villainy, often also combining her with Morgan.
* VillainousIncest: In the variations where she's aware of her relation to Arthur.
* YourCheatingHeart: Cheated on Lot with Arthur during her time as a HoneyTrap.

[[folder: Morgan(a) Le Fay]]
* ArchEnemy: ''Guinevere's'', actually. After a few unsuccessful attacks on Arthur, Morgan mostly devoted herself to trying to reveal Lancelot and Guinevere's affair.
* CompositeCharacter: Many adaptations fuse her with Morgause.
* DependingOnTheWriter: In her earliest appearance, Geoffrey's ''Life of Merlin'', "Morgen" was the chief of the healers of Avalon. Later medieval writers made her a villain. Some modern writers, most famously Creator/MarionZimmerBradley, have written of her sympathetically.
* EvilMatriarch: Many versions make her this to Mordred.
%%* [[EvilSorcerer Evil Sorceress]]
* GreenEyedMonster: Apart from the incident in YourCheatingHeart below, part of Morgan's hatred for Guinevere may have stemmed from the fact that she herself wanted to sleep with Lancelot.
* HeelFaceTurn: In time she seems to have mellowed out and gotten along well with Arthur, to the point of letting him visit her castle for a week. Of course she still tried to convince him of Guinevere's unfaithfulness, but [[SelectiveObliviousness he didn't believe her]].
%%* HotWitch
* LadyOfBlackMagic: She's a potent witch, and almost always portrayed as beautiful lady garbed in regal dresses.
* LegionOfDoom: At one point King Mark appeals to her to get a bunch of evil sorcerers and known evil knights together in order to ravage Arthur's kingdom.
* MurderIsTheBestSolution: Tried to kill her husband King Uriens, but was stopped by their son Ywain.
* SpellMyNameWithAnS: Morgan, Morganna, Morgaine, etc.
%%* WickedWitch
* YourCheatingHeart: Cheated on Uriens with Guinevere's cousin Guiomar. When Guinevere found out, she had Guiomar banished. (Understandably, Morgan was rather peeved when [[{{Hypocrite}} Guinevere started her affair with Lancelot.]]) She then proceeded to take on several lovers without actually getting a divorce.

[[folder: Nimue/Nyneve/Viviane/The Lady of the Lake]]
* See '''Characters/TheLadyOfTheLake'''.

[[folder: Iseult the Fair]]
* ArrangedMarriage: With King Mark of Cornwall.
* DeathByDespair: After Tristan's death she also dies because of grief.
* DudeMagnet: There's a ''lot'' of guys who become attracted to her, [[RuleOfDrama mainly so they can have a conflict with Tristan about her.]]
* GuileHero: Just like her lover, she often has to use her wits to keep her adultery secret.
* HealingHands: She is the only one who can heal Tristan when he gets fatally poisoned.
* SpellMyNameWithAnS: There are tons of alternate spellings for her; like Isolt, Isolde and Isolda just to name a few.
%%* StarCrossedLovers
%%* TogetherInDeath
* YourCheatingHeart: Cheats on her husband Mark with Tristan.

[[folder: Iseult of the White Hands]]
* GreenEyedMonster: Becomes jealous of the other Iseult when she learns of Tristan's love for her, leading her to kill Tristan through lying.
* OneSteveLimit: Defied; having the same name as another character is the reason she becomes Tristan's wife, and thus a character in the story, in the first place.
* ReplacementGoldfish: Tristan marries her because she has the same name as his lover.
* TilMurderDoUsPart: She indirectly murders Tristan by claiming that Iseult the Fair isn't coming to heal him, causing him to give in to despair and succumb to his poison just as Iseult arrives to cure him.

[[folder: Ettard of Arroy]]
* ButtMonkey: So one day you decide to go to a tournament, and this creepy guy who beat sixty knights proclaims his love for you out of nowhere. You tell him where to get off, and he decides to follow you home instead. When you send people to get rid of him, he uses it as an excuse to meet you in person. Over and over. Finally, a knight you're ''actually'' into tells you he's killed your stalker, bringing his armor as proof. You sleep with him out of gratitude, but whoopsie, he was deceiving you -- you find this out because your stalker ''sneaks into your room and leaves his sword lying across your throat while you're asleep''. Good morning! But hey, it looks you're rid of him at last...until some lady shows up on your doorstep and calls ''you'' out for treating ''your stalker'' badly. And then she casts a spell to make you fall for him and make him hate you. [[DeathByDespair And then you]] '''[[DeathByDespair die.]]'''
* SoBeautifulItsACurse: Interestingly, she's apparently not ''that'' beautiful, but considering what her looks get her, it fits.
* SpellMyNameWithAnS: Ettarre, Ettarde

!Other Kings

[[folder: Uther Pendragon]]
Arthur's father.
* AndNowYouMustMarryMe: Made his attraction to Igraine known while she was still married to Duke Gorlois, and laid siege against Gorlois' castle until the Duke was killed and his allies sued for peace, whereupon he married her the very same night. Doesn't look like she had much choice in the matter.
* AntiHero: UnscrupulousHero. A strong king, who seems to have ruled fairly, but definitely not what you would call a good person.
* BedTrick: Had Merlin give him the appearance of Duke Gorlois so he could sleep with Igraine, conceiving Arthur.
* DeathByOriginStory: Arthur becomes king because of his death, being his son and all, but he is plucked from a life of obscurity with a foster-family and thrust onto the throne at a young age. Details vary though.
%%* TheHighKing
* {{Jerkass}}: A real piece of work, as the other entries show.
* KickTheDog: Jokingly needled the already-nervous Igraine about who (or what) the father of her child might be, considering Gorlois was dead on the battlefield when it was conceived. When he finally reveals the [[BedTrick truth]], it's noted that she's quite relieved, as opposed to belting him one. When Arthur was actually born, he gave the kid to Merlin without consulting her first or explaining why. Husband of the Year material, here.
* NamesToRunAwayFromReallyFast: ''Pendragon'' is a Welsh epithet (sometimes treated as a surname or dynastic name by later authors) which translates to "Chief Dragon" in English, "dragon" probably being a figurative term for warrior. "Uther" itself may come from a Welsh word meaning "awesome" and/or "horrible/terrible" (in the original sense of "fearsome" rather than "bad").
* SecondLove: For Igraine, apparently. At any rate she actually seemed to be quite upset when he died.

[[folder: Vortigern]]
A king who ruled just before Uther's time.
* ZeroPercentApprovalRating: Everybody came to hate him, meaning he used the Saxons... which made him even more unpopular.
* AntagonisticOffspring: His own sons rebelled against him, and he was kicked off the throne temporarily.
* FamilyThemeNaming: Had sons named Vortimer, Catigern and... [[OddNameOut Pascent]].
* TheHighKing: Before Uther's time.
* HistoricalDomainCharacter: One of the few Arthurian figures historians generally agree was real. Since "Vortigern" means something like "overlord" in Brittonic, it's disputed whether it ought to be taken as a title, or his real name since he seems to have practiced FamilyThemeNaming.
* HoistByHisOwnPetard: Allowed the Saxons, Angles and Jutes to settle in Britain in order to serve as his mercenaries. They turned on him and Uther and Arthur would have to fight them.
* KillItWithFire: One version of his death has him trapped in a burning tower.
* TheUsurper: He is said to have seized the throne after betraying Uther's brother and/or father (depending on the story)
* WalkingTheEarth: Another version of his death has him die in obscurity after going into exile and wandering about.
* WouldHurtAChild: Tried to build a tower that kept tumbling down and was told that only [[HumanSacrifice the blood of a child]] with no human father could secure it. That child was Myth/{{Merlin}}, who had other ideas.

[[folder: Ambrosius]]
A king who ruled just before Uther's time.
* BigGood: For the monk Gildas, who in his writings chews out every British ruler he names, except him who he treats as TheParagon.
* DeathByOriginStory: In Geoffrey, Uther's older brother who briefly ruled as king before him, replacing Vortigern. He dies of poison and Uther succeeds him. He's often skipped in modern retellings.
* TheHighKing
* HistoricalDomainCharacter: Another Arthurian figure who historians agree was real. In his earliest mention by Gildas, he appears as the one who rallied the Britons against their Saxon foes with no mention of Arthur or Uther. Nennius mentions him too as a rival lord of Vortigern who later became high king. Arthur is instead mentioned as a general fighting for the British kings. Later accounts explicitly claim Arthur fought for Ambrosius. Even later accounts omit Ambrosius entirely.
* LastOfHisKind: Gildas calls him the "last of the Romans" in Britain.
* OracularUrchin: Most curiously, he first appears in Nennius as the boy without a human father who Vortigern encounters--in later retellings starting with Geoffrey, the boy is Merlin.
* RightfulKingReturns: When his brother Constans is murdered and Vortigern usurps the throne he and Uther are too young to rule and are forced to flee to Brittany. They return later and depose Vortigern.
* SpellMyNameWithAnS: The earliest source, Gildas, calls him "Ambrosius Aurelianus". Geoffrey calls him "Aurelius Ambrosius".

[[folder: Lot of Lothian and/or Orkney]]
The father of Gawain and his brothers.
* AdaptationalVillainy: Wasn't a villain in Geoffrey of Monmouth, but is one from the Vulgate Cycle onward.
* DefeatMeansFriendship: After being a StarterVillain. But in some versions Arthur's [[NiceJobBreakingItHerod baby-killing]] drives him to rebel again, leading to his death.
* EvenEvilHasLovedOnes: In some versions, Sir Gawain and his brothers pursue a BloodFeud with King Pellinore and his family after Pellinore kills him--despite Lot having rebelled against Arthur.
* SpellMyNameWithAnS: Loth.
* StarterVillain: The leader of a group of rebel kings in the early years of Arthur's reign.

[[folder: Lucius Tiberius]]
Procurator (sometimes Emperor) of Rom who makes war with Arthur's allies in Gaul, causing Arthur to come down (leaving Mordred and/or Lancelot in charge) to fight him.
* KlingonPromotion: Defeating Lucius is apparently enough to get Arthur declared Emperor.
* OutsideContextProblem: Essentially comes out of nowhere to shake things up.
* SpellMyNameWithAnS: Sometimes Lucius Hibernus, both of which are suspected to be misspellings of Glycerius.
* UnwittingInstigatorOfDoom: Distracts Arthur long enough to let his court intrigues destroy Britain.
* WritersCannotDoMath: If Badon Hill happened in about 500 AD, it was far too late for any Western Roman Emperor to start making trouble in Gaul -- the last Emperor of the West, Romulus Augustulus, was deposed in 476 AD, and the western empire ceased to have any power worth speaking of long before that.

[[folder: Pellinore]]
* BlackKnight: Sometimes fights one. Sometimes is one, as in Howard Pyle's retellings.
* DefeatMeansFriendship: He defeats Arthur after being challenged to joust. The Sword in the Stone breaks during their fight, to be replaced by {{Excalibur}}. Arthur later asks him to join the Round Table.
* FamousAncestor: Joseph of Arimathea.
* FeudingFamilies: He killed Lot in combat, touching off a feud with the Orkney brothers which culminated in his death at the hands of Gawain and Gaheris and, later, the death of his son Lamorak.
* TheQuest: Pursues the Questing Beast.
* ReallyGetsAround: Has four legitimate sons with his wife, and at least three illegitimate children with three different women.
* TragicMistake: In his haste to rescue Nimue, he refused to stop and provide aid to a gravely wounded knight and his lady. He didn't learn until after the rescue that the lady--who killed herself with her dead lover's sword--was his daughter Eleine.

[[folder: Mark of Cornwall]]
Uncle of Tristan, husband of Isolde.
* AdaptationalVillainy: Goes from a sympathetic cuckold in the original story to an evil DirtyCoward in ''Prose Tristan'' and later tales, then loops back around in many modern works.
* BadBoss: Occasionally flew into rages where he killed his own men.
* CainAndAbel: Evil!Mark kills his brother.
* IncestIsRelative: Evil!Mark rapes his niece and kills her after she gives birth to his son.
* LittleBitBeastly: Gets cursed with a horse's ears and mane in an early Breton legend, paralleling a legend about King Midas after he lost his touch. This is also a pun on "march", Welsh for "horse".
* PetTheDog: Erected a rich tomb over a slain knight and [[DrivenToSuicide his lady]], apparently as a gesture of legitimate kindness.

[[folder: King Pellam of Listeneise]]
* FamousAncestor: Joseph of Arimathea.
* FisherKing: After receiving the Dolorous Stroke, his castle collapsed and his kingdom became a wasteland until he was healed by blood from the Spear of Destiny.
* GoodIsImpotent: Either unwilling or unable to stop Garlon from murdering people.
* GroinAttack: Appears to have been the original location for his WoundThatWillNotHeal. Dolorous, indeed.
* MultipleChoicePast: The myths have multiple maimed Fisher Kings, who may have [[DecompositeCharacter originated as one character]], even a knight of Arthur's, and two different versions of the Dolorous Stroke:
** When out hunting he happened upon Solomon's Ship and [[OnlyTheChosenMayWield King David's Sword]] within. Feeling himself worthy, he had the temerity to try and draw the sword, whereupon a spear appeared out of thin air an delivered the Dolorous Stroke, impaling his thighs.
** When Sir Balin killed Sir Garlon at one of Pellam's feasts, the king broke SacredHospitality and attacked his brother's killer, breaking his sword. Balin fled, with Pellam in pursuit, until the reached the Grail Chamber, where he desperately grabbed the first weapon he could find and lashed out at the king--striking the Dolorous Stroke with The Spear of Destiny and bringing the castle down upon their heads.
* SiblingYinYang: The "most worshipful man that lived", his brother Sir Garlon was a vicious SerialKiller with the power of {{invisibility}}.
* WoundThatWillNotHeal: However he received it, and wherever it is (hip, groin, thighs), the Dolorous Stroke doesn't heal until Galahad uses blood from the Spear of Destiny to cure it.

!Other Characters

[[folder: Adragain the Brown]]
Appears in the Vulgate Merlin, Vulgate Lancelot, Le Livre d'Artus and Arthour and Merlin.

* SpellMyNameWithAnS: Adragein(s), Adragenis, Agrauein(s).
* UndyingLoyalty: He previously served under Uther and later for his son Arthur.
* WhatTheHellHero: His reaction to Arthur failing to help Kings Ban and Bors against Claudas's second invasion of their lands.

[[folder: Affalach]]

%%* OurGodsAreGreater

[[folder: Alain the Large]]
* FisherKing: One of them to be exact.
* FlipFlopOfGod: Robert de Boron early on wrote that he was celibate only to contradict himself latter by stating that he fathered several children.

[[folder: Belinus & Brennius]]
!!Belinus and Brennius
Two brother Kings of Britain said to have led the Celtic sacking of Rome in 390 B.C.
* HistoricalDomainCharacter: This seems to be a garbled account of the real Gaulish sacking of Rome, led by one Brennus.

[[folder: Brutus of Troy]]
According to Geoffrey of Monmouth and subsequent authors, a Trojan exile who led a band of followers and conquered Britain from a race of giants. Britain was supposedly named after him.
* DependingOnTheAuthor: He is said to be either [[Myth/ClassicalMythology Aenea's]] grandson or great-grandson.
* DidYouJustPunchOutCthulhu: He and his band of Trojan exiles defeated an entire island of Giants to claim what would later be named Britain (after Brutus) for themselves.
* FounderOfTheKingdom: And London, originally New Troy.

[[folder: Culhwch]]
Arthur's cousin from the Welsh tale of Culhwch and Olwen.
* EngagementChallenge: Has to do an impossible series of tasks to win Olwen's hand.

[[folder: Ector]]
The father of Kay and foster father of Arthur.
* GoodParents: To all indications he treated Arthur as lovingly as his natural-born son, and upon learning that he was the true King of England requested only that Kay be made seneschal.
* MuggleFosterParents: After Arthur's royal parents died, Sir Ector raised Arthur, never knowing his foster son's true identity.
* SpellMyNameWithanS: Hector or Antor (French/Breton/German), Cynyr (Welsh).

[[folder: Hengist & Horsa]]
The pair of brothers who, according to legend, began the Anglo-Saxon invasions that transformed a decent chunk of Great Britain into England. Sometimes identified as Angles or Jutes instead of Saxons, but then the Britons (and Scots and Irish) tended to lump all the Germanic invaders together under "Saxon".
* AnimalThemeNaming: Hengist means "Stallion," while Horsa means... "Horse."
* HeroicLineage: A few generations removed from ''Odin''. Not quite DivineParentage but still.
* HistoricalDomainCharacter: Maybe. Their legends might preserve memories of real leaders, but on the other hand, heroic and often divine twins is a recurring motif in mythology. Hengist himself is also mentioned in ''Literature/{{Beowulf}}'' and the ''Literature/ProseEdda''.
* IntercontinuityCrossover: Hengist may create one, as his appearance in ''Literature/{{Beowulf}}'' ties the Arthurian mythos into Germanic and Norse mytholgy.
* FaceHeelTurn: They initially earned their keep fighting people fro the Britains, then broke off to become invaders.
* GreaterScopeVillain: For the early legends which deal primarily with Arthur fighting the Saxon invasion; traditionally, both men are dead by this time, but their armies and kingdoms are still waging war on the native Cymry.
* HiredGuns: Their intial occupation, and indeed the reason they were invited to Britain in the first place; Vortigern required an army to fight invading Scots and Picts.
* NastyParty: Hengist pulled one on Vortigern and his nobles. At his signal, the Saxons drew hidden knives and slaughtered the Britons--sparing only Vortigern, who was then subjected to blackmail.
* SatelliteCharacter: Horsa is always secondary to Hengist, and dies before him.
%%* SiblingTeam
* SpellMyNameWithAnS: Hengest and Hors

[[folder: Rowena]]
The beautiful daughter of Hengist who became the wife of Vortigern. This gave Hengist some claim on the British throne.
* HoneyTrap: Hengist had her entertain Vortigern at a feast and he was quickly smitten. Soon, Hengist not only became his father-in-law but gained even more land for the Saxons.
* KillItWithFire: Sometimes said to have died together with Vortigern this way.
* SecondLove: In some tellings Vortigern was already married once, and sometimes his first wife is even still alive. Either way, their relationship offends his sons who eventually rebel.
* SpellMyNameWithAnS: Renwein, Renwen, Rhonwen, Ronwen, Rowen... the form Rowena later became better-known though Creator/WalterScott's ''Literature/{{Ivanhoe}}''.
* UnholyMatrimony: The Britons or at least the Church thought so, for not only was she Saxon but also pagan.
* WickedStepmother: She had her stepson Vortimer poisoned when he briefly deposed his father. In some versions she fakes a HeelFaithTurn to get on his good side.

[[folder: Cerdic]]
One of the first Saxon leaders.
* DecompositeCharacter: Geoffrey appears to have split him into three figures: ''Cherdic'', a contemporary of Vortigern; ''Cheldric'', one of the enemy leaders at Badon; and ''Chelric'', an ally of Modred at Camlann.
* FounderOfTheKingdom: Of Wessex (named after the "West Saxons"). The royal dynasty of Wessex, most notably UsefulNotes/AlfredTheGreat, claimed him as their ancestor.
* HeroicLineage: Also descended from Odin.
* HistoricalDomainCharacter: Probably, which is why he tends to pop up in modern historical-leaning Arthurian fiction despite having little presence in the medieval legends. Curiously, his name appears to be Brittonic instead of Germanic, as it's related to Ceretic/Caradoc/Caratacus, leading to speculation about whether he was part or full Briton despite leading non-Britons, and whether the distinction was even all that important back then.
* TheQuisling: Maybe, since a certain Ceretic appears in the ''Historia Britonum'' as Vortigern's interpreter when dealing with Hengist.
* SpellMyNameWithAnS: Not directly mentioned as "Cerdic" in any of the legends, only historical or pseudo-historical material, but nevertheless his name does appear through variants or in garbled form as seen above. Walter Scott also misspelled his name as "Cedric" in ''Ivanhoe'' and it has since become a common name.
* VillainProtagonist: Of the ironically-titled novel ''Conscience of the King'' by Alfred Duggan.
* WorthyOpponent: A common interpretation of him in modern Arthurian fiction, including the film ''Film/KingArthur'' where he's the main antagonist.

[[folder:Osla Big-Knife]]
One of Arthur's companions in the tale of Culhwch and Olwen.
* {{BFS}}: His knife is big enough to serve as a bridge.
* DefeatEqualsFriendship: Implied, as another Welsh tale, "The Dream of Rhonabwy", mentions him as the Saxon leader at the battle of Badon. It's also worth noting that the Saxons probably derived their name from ''seax'', a kind of knife.
* HistoricalDomainCharacter: May be based on King Offa of Mercia (another Saxon kingdom), though he lived centuries after the first Saxon incursions so the two may have been confused instead.
* HoistByTheirOwnPetard: While helping Culhwch with his {{Engagement Challenge}}s, he apparently drowns in a river after his scabbard fills with water.
* RedBaron: ''Gyllellvawr'' or ''Kyllellvawr'', meaning Big Knife. Offa of Mercia is called the same in historical records.

[[folder: The Black Knight]]
* DarkIsEvil: Usually, but not always.
* MeaningfulName: Wears black armor.
* NamesTheSame: There are actually several characters known as "The Black Knight" throughout the Arthurian mythos, and not all of them are evil.

[[folder: The Green Knight]]
* AnAxeToGrind: The Green Knight's favorite weapon is a great ax, with which he threatens to behead Sir Gawain.
* BlackKnight: Except green. He isn't really evil though.
* LosingYourHead: But his head still talks.
%%* MagicKnight
* MeaningfulName: He is completely green, as well as his gear and horse, and he carries a bough of holly in one hand (and an axe in the other). Some scholars think he may have pagan roots as a [[NatureSpirit nature]] [[AnthropomorphicPersonification figure.]]
%%* {{Trickster}}
