[[folder: Duncan [=MacLeod=]]]

The main character and protagonist of the show, Duncan was raised as the son of the chief of clan [=MacLeod=] until his Immortality was revealed and he was cast out. He lived for some years in the Scottish wilderness before rumors of his existence reached the ears of his elder and kinsman, Connor [=MacLeod=]. Connor found Duncan and began teaching and training the younger [=MacLeod=], travelling throughout Europe. Duncan would return to Scotland several times through the ages to attempt to hep them overthrow British rule, but the defeats suffered by the Scots eventually made him give up that goal. He travelled all throughout the world, often serving again as a soldier until an encounter with the monk Darius convinced him to begin rethinking living a soldier's life forever and moving into more peaceful trades. In the present he splits his time between Paris and the (fictional) city of Seacouver, working as an antiques dealer.

For all the time that's been alive and all that he's been through, nothing has shaken Duncan's firm belief in his principles, right and wrong, good and evil. He will defend and fight for any person he sees as righteous, regardless of whether he benefits from it or not, and against anything he sees as wrong.

* BadassLongcoat: Usually a black one. It's used to {{Handwave}} where he keeps his sword.
* BeenThereShapedHistory: Duncan seems to appear everywhere important in the past four hundred years. For just a few examples: he's fought in the Jacobite rebellions, he was at Waterloo, fought for the Union in American Civil War and been imprisoned in the infamous Andersonville prison camp, partied with Cossacks in Russia, took alchemy and martial arts lessons in China, washed up in Tokugawa era Japan in a shipwreck, lived on the plains with a tribe of the Sioux, was a stretcher bearer in WWI, etc.
* BigBrotherMentor: to Richie.
* ChronicHeroSyndrome: It doesn't matter if they're a complete stranger he's never met, Duncan will attempt to help them.
* CulturedBadass: He runs an antique store, can speak multiple languages, has excellent taste in wine and art, and is an expert swordsman.
* DatingCatwoman: He's the Batman to Amanda's Catwoman, but they do get along fairly well nonetheless.
* DevourTheDragon: [[spoiler:A rare heroic version in the Endgame movie, where he faced an opponent strong enough that Connor concluded that the two could only defeat him if their powers were combined, and then Connor all but forced Duncan to take his head.]]
* HairDecorations: He occasionally wears a engraved metal hair clip , and is fond of wearing a decorative button of some kind on his hair tie.
* {{Hammerspace}}: There were times in the show when he pulled his sword out between cuts when he had no place to conceal it anywhere.
* HappilyAdopted: Duncan didn't even know he was a foundling until his first death. After he was banished from the clan, his mother still insisted "It matters not who bore you, you ARE my son!" Even 400 years later, Duncan's recollections of his parents are loving and respectful. He even still wears his clan name as a badge of honor and saves the modern members of his clan from a evil immortal out of a sense of duty, despite them banishing him as a demon.
* HonorBeforeReason: Duncan has such a strong code of honour that he's walked into things he knows are traps rather than violate it.
* IAmXSonOfY
--> I am Duncan [=MacLeod=] of the Clan [=MacLeod=].
* KatanasAreJustBetter: While Duncan never outright says this about katanas in general, his specific sword has broken at least two other blades and chopped a desk in half with no signs of damage. The first owner of the sword even makes a comment stating how much better it is than the European blade Duncan was wielding at the time, (and the katana cut the blade right off it like a piece of bamboo) and Duncan is pretty amazed by it even though he grew up a warrior and probably handled all kinds of swords up to that point.
* MrFanservice: He fights shirtless several times, and gives a full view of his backside at least once. (twice if you count Endgame)
* MyCountryRightOrWrong: He never let go of his Scottish heritage and has fought for his homeland at different times in history.
* NiceGuy
* NotHimself: The Dark Quickening.
* PermaStubble
* RealMenLoveJesus: Like Connor, is still astoundingly a devout Catholic in spite of being banished by the xenophobia of his Catholic kin.
* SlipknotPonytail
* TheCoatsAreOff
* TheStoic
* StraightMan
* WarriorPoet: Much like Connor, he is a patron for music, poetry, fine arts, not to mention wine and fine cooking.

[[folder: Methos]]

-->''"Why would I tell the truth?"''

The legendary oldest Immortal, Methos has been alive for at least 5000 years... and we say at least because as Methos himself says, before that, everything begins to blur, and now even he doesn't remember all of his life. Although a capable fighter, the true reason Methos has lived so long is because he's clever, cynical, self-serving, and possesses a keen insight into people, and time has only added onto these attributes. (Particularly the cynicism.)

At some point, Methos learned about The Watchers, a secret society that has observed and tracked Immortals and The Game for centuries. In the modern day, he joined The Watchers under the alias of Adam Pierson and became the group's foremost expert on the legend of Methos, a legend that few people believe in. Methos preferred to continue that trend, as he would rather keep a low profile and quietly enjoy life than be a target for every power hungry Immortal who wanted the Quickening of an ancient. As a researcher among The Watchers, Methos was able to mostly avoid other Immortals, and edit details about himself as he chose, recording some details of his life and obscuring others so that his true identity would be impossible to discover. When the evil Immortal Kalas learned about The Watchers and began hunting for Methos, however, he was reluctantly forced back into The Game and became allies, and later friends, with Duncan.

While he has spent much of his long life in professions such as a scholar, adviser, scribe and doctor, it's natural that being as old as he is, not all of Methos' life has been squeaky clean and heroic. [[spoiler:Most infamously, he was once part of a band of four Immotrals (along with Kronus, Silas, and Caspian) who raided and pillaged across the world for centuries, inspiring the concept of the Four Horsemen along the way. Methos served primarily as the group's tactician and planner, until dissension with Kronus and his experiences with Cassandra, a newly made Immortal who became his slave and lover after the Horsemen destroyed her village, caused him to begin reconsidering his life. He eventually left the group, and it dissolved afterward, although he would encounter them again in the present day]].

* TheAtoner: Downplayed. Claims not to feel guilt for [[spoiler: his time as one of the [[HorsemenOfTheApocalypse Four Horsemen of the Apocalypse]], but still turns on his former brothers-in-arms when they want to spread a plague that would most likely kill thousands of mortals.]]
* BadassBookworm: Works at a university when we first meet him, and claims to have been writing almost since writing began, which, considering how uncommon a skill it was in the ancient world, is saying something, especially since he seemed to spend many of his early years [[spoiler:[[RapePillageAndBurn doing nothing but killing people and smashing things.]]]]
* BiTheWay: Seemed to be tempted by Byron's offer to have a threesome with Mary Shelley, but turned him down when he seemed to remind himself that she was too out of it to refuse them, and that he [[TheAtoner was no longer]] [[RetiredMonster that kind of man.]]
* BigBrotherMentor: To Duncan, when Duncan will actually listen.
* BrokenPedestal: [[spoiler:When Duncan found out the atrocities he committed as one of the Four Horsemen]]
-->'''Methos''': [[spoiler:I killed. But I didn't just kill fifty. I didn't kill a hundred. I killed a ''thousand''. I killed ''TEN THOUSAND!'' And I was good at it. And it wasn't for vengeance. It wasn't for greed. It was because... I liked it. Heh. I ''liked'' it. Do you know who I was? I was '''''Death!''''']]
* CombatPragmatist[=/=]FightingDirty: Including tactics such as [[MoreExpendableThanYou shooting Duncan in the back]] when Duncan is being a little too brash due to HonorBeforeReason, or [[GroinAttack stabbing an opponent in the groin]] with a concealed dagger.
* DarkAndTroubledPast: [[spoiler: see BrokenPedestal above]]
* DeadpanSnarker: Especially when someone implies his age should make him a wise man.
* FeelingTheirAge: Methos says "I'm too old for this" in the episode "Deliverance" after Duncan throws him over a wall to land several feet below. Double subverted example, since he's an [[TheAgeless ageless immortal]] who will always be in his physical prime, but at the same time he actually is 5000 years old. If he can't feel too old for this, who can?
* TheFogOfAges[=/=]TimeAbyss: Methos isn't even sure how old he is. His memory goes back five thousand years and "before that, it all starts to blur." Joe Dawson describes him as "An Immortal who's so old, he can't remember the time of his birth."
* GoodIsNotNice: Fights even dirtier then some of the villains, and even kills a evil female immortal when Duncan's sense of chivalry won't let him finish the job
* GuileHero: One of the main reasons he's survived so long is because he's good at [[TheStrategist judging his opponents]] and [[BatmanGambit outsmarting them]].
* [[VillainForgotToLevelGrind Hero Forgot To Level Grind]]: Played with. Methos flat out isn't really interested in level grinding as he's more about intellectual pursuits these days, plus he knows it's far easier to survive by being smart and willing to walk (or run) away from a fight than by being the best warrior, so when he first appears he's badly out of practice at Immortal combat. Even so, he's good enough to beat most Immortals and there are hints throughout the series that Methos could be a more dangerous opponent than some "better" fighters due to a combination of ruthless pragmatism, fighting dirty, and learning quickly from any mistakes he makes or things he sees others do. (As an example of that last bit, in one episode Methos is defeated by Duncan in a sparring session, then at the end of the episode uses the same technique Duncan used to defeat him in order beat the VillainOfTheWeek.)
* HeroicSelfDeprecation[=/=]CowardlyLion: Whenever [=MacLeod=] seeks his advice on matters of honour, Methos always advises him to run away, insisting that he himself wouldn't risk his life for anybody. Yet at the same time he is risking his life to bring Mac back from the Dark Quickening, and duelling immortals on his behalf. Methos talks like a coward, but he doesn't act like one.
* HiddenInPlainSight: Under the alias of [[MeaningfulName Adam]], he joins the Watchers, and gets himself assigned to tracking down... himself.
* LivingForeverIsAwesome: While he has plenty of regrets, he also treasures continuing to live, have new experiences and new things to learn.
* ManipulativeBastard: [[spoiler:Manages to pull of false FaceHeelTurn and plan the fall of the Horsemen from the inside]]
* MayflyDecemberRomance: With Alexa, who only had a year to live when they met.
-->'''Methos:''' I know she's dying, okay? You are all dying. Twenty years. Six months. What's the difference?
* MinoredInAsskicking: Prefers not to fight at all in the present day, and will avoid challenges if he can, but [[CurbStompBattle curb stomped]] a couple of the opponents he ''couldn't'' avoid fighting, nonetheless.
--> Methos: "Just because someone doesn't ''like'' to fight doesn't mean they ''can't''."
* TheOlderImmortal: The oldest living man on earth at 5000+ years, even other immortals thought him a myth.
* ReluctantWarrior: He would prefer to stay out of the Game, but see UnderestimatingBadassery for what happens when someone tries to force the issue.
* RetiredBadass: Or wants to be, anyway.
* RetiredMonster: [[spoiler:Even has one of the page quotes. However unlike the classic RetiredMonster he ''is'' sorry and atones by destroying his comrades, who have ''not'' retired.]]
* ShootTheDog: How he regards the idea of taking the head of Duncan's PsychoExGirlfriend Kristin.
-->Someone had to do it.
* ShroudedInMyth: Even among Immortals he's considered a urban legend.
* TimeAbyss: Can't remember much before his first quickening.
* TrademarkFavoriteFood: cheap beer.
* TricksterMentor: To everyone. He never teaches a lesson straight out if he can help it.
* UnderestimatingBadassery:
** Several people have underestimated him because he usually avoids conflict. In one case, a possessive immortal who hates that Methos slept with his slave tracks him down in the present day, using both Joe Dawson and [[spoiler:Joe's daughter]] as bait. Said immortal thinks Methos is a weakling and a coward, and expects to easily beat him. Instead Methos [[CurbStompBattle curb stomps him]], and the last words the other immortal hears is Methos saying "Just because someone doesn't ''like'' to fight doesn't mean they ''can't''."
** You've also got to remember that this is the man who, as a member of [[spoiler:[[HorsemenOfTheApocalypse the Four Horsemen]]]], took the moniker of [[spoiler:Death]].
** Also, in the bad timeline shown in the last episodes where [[ItsAWonderfulPlot Duncan was never born]], Methos went on one ''hell'' of a RoaringRampageOfRevenge when the Watchers are taken over by Horton, who begins slaughtering immortals and kills Methos' mortal lover in an attempt to get to him. Methos promptly [[spoiler:teams back up with his old partner Kronos]] and begins leading the war against the Watchers. Their actions are described thusly: "They made [[TheMafiya the Russian Mafia]] look like choir boys."
* WouldHitAGirl: He was alive for thousands of years before the idea of chivalry came along. And while he rarely gets involved in violence if he can help it, he shows no more qualms about fighting a woman than he does a man.
-->'''Kristin Gilles''': Who the hell are you?!\\
'''Methos''': A man born long before the age of chivalry.

[[folder: Amanda]]

A sly and manipulative Immortal who has been a thief for most of her long life, Amanda has had several run-ins with Duncan and maintained an oddly good relationship despite her methods and profession being quite at odds with his dedication to old fashioned morality.

* BattleCouple: Her and Duncan become this later in the series after the season 3 finale brings the pair the closest they've been in their 300 year long relationship.
* BettyAndVeronica: with Tessa
* BoyishShortHair: Her most consistent hairstyle, although its not matched by a boyish personality.
* ClassyCatBurglar
* CryIntoChest: Did this with Duncan after she discovered her teacher Rebecca had been killed. Its one of the very rare occasions she breaks down.
* DamselOutOfDistress: Kalas captures her in the season 3 finale in order to bait Duncan. To bad her guards didn't know 1,000 years of being a FemmeFatale and thief gave her plenty of time to become an exceptional escape artist as well.
* FemmeFatale
* KillSteal: In her first appearance she decapitates a disarmed immortal seconds before Duncan would have killed him.
* MamaBear: To Kenny, at least until she finds out what he really is.
* OvershadowedByAwesome: Amanda hangs around and is friends with Immortals like [[TheHero Duncan]] and [[TheOlderImmortal Methos]]. She obviously lived 1,000 years by putting up a good fight, but she rarely gets to show off and is often outclassed since the villains have to match the heroes, all of whom are better than her at fighting.

[[folder: Tessa Noel]]

Duncan's longtime companion and love interest at the start of the show, Tessa is a skilled artist and empathic soul. In season 2 she was kidnapped by a rogue Watcher who had abducted the loved ones of Immortals so he could lure them to their deaths. Duncan managed to save Tessa, but while he was trying to learn more about her kidnapper from the man's computer, Tessa was attacked and killed by a mugger.

* BettyAndVeronica: While Amanda is the much older, far more dangerous and glamorous thief, Tessa is sweet, stable and devoted.
* DamselInDistress: Several villains kidnapped her to get to Duncan, preying on his desire to AlwaysSaveTheGirl.
* HairOfGoldHeartOfGold: She's sweet, artistic, non-violent, and feminine [[BewareTheNiceOnes except when she threatens to burn off your face with a welding torch.]]
* KilledOffForReal: She's killed in the second season in the same mugging that makes Richie Immortal, thus highlighting the contrast between muggles that die permanently and immortals that [[CameBackStrong come back stronger]].
* TheLostLenore: With her early death, she has more impact on Duncan's motivations dead than alive.

[[folder: Richie Ryan]]

A foster child who grew up as a tough street kid, Richie became a thief and was planning to rob Duncan's antique store in the show's first episode when suddenly he witnessed the start of a battle between Slan Quince, Connor, and Duncan. Connor and Duncan recognized Richie as an Immortal who hadn't died his first death yet and triggered his Immortality, so Duncan kept Richie close afterwards, under the pretense that it was because of Richie stumbling onto Immortals. He died at the same time that Tessa did, and afterward became Duncan's full fledged student.

* AxCrazy: After Duncan is afflicted by the Dark Quickening and [[spoiler: tries to kill him]], Richie decides to devote himself to The Game, and goes on a nationwide Immortal killing spree.
* BadassAdorable: He didn't take many heads on-screen, but the Immortals he ''did'' defeat included [[BountyHunter Mako]] (~700 years), [[TheMafiya Ivan Kristov]] (~400 years), and [[HoYay Carter Wellan]] (~1000 years). And he [[http://swordforum.com/fall99/ssw-stan-kirsch.jpg looks like this]].
* ChronicHeroSyndrome: He developed a case almost as bad as Duncan's especially for any passing DamselInDistress. The plots of a number of episodes are kick started by this trait.
* DroppedABridgeOnHim: [[spoiler: Richie stumbles across Duncan while the latter is under the influence of Ahriman's hallucinations. Thinking that Richie is an enemy, Duncan decapitates him.]]
* FosterKid: As immortals are all foundlings, Richie wound up in the foster system.
* MentorOccupationalHazard: Inverted. [[spoiler: It's Richie who dies. Not Duncan.]]
* NaiveNewcomer: When Duncan takes Richie in, he has no idea that he's a pre-immortal or that immortals even exist.
* {{Sidekick}}: He serves as a sidekick to Duncan giving him another set of hands and someone to bounce ideas off of.
* StreetUrchin: Starts out this way before Duncan and Tessa take him in after they catch him breaking into the antique shop.
* TrainingMontage: There are a number of these with Duncan teaching him how to wield a sword.

[[folder: Joe Dawson]]

A Vietnam War veteran who lost both legs during the war but lived after his life was saved by his Immortal squad mate Andrew Cord, Joe Dawson later became part of The Watchers and became the Watcher of Duncan [=MacLeod=] himself. Despite Duncan's suspicions of The Watchers, (having unknowingly encountered rogue Watchers in the past, and rogue Watchers in the present having been responsible for the murder of Darius) Joe soon proves his character and sincerity to Duncan, and the two become close friends.

After becoming friends and allies, Joe frequently becomes Duncan's go to source for information about the latest Immortal to be a threat to Duncan or the people around them.

* BadassNormal: Even more impressive than usual as he manages to be this trope while a [[HandicappedBadass double amputee]].
* CoolOldGuy: Joe Dawson is epitome of coolness.
* DefiantToTheEnd: [[spoiler: Granted that he winds up not dying.]]
-->'''Charles''': On your knees
-->'''Joe''': ''(laughs)'' Not in this lifetime.
* FaceDeathWithDignity: Joe knows the rules of being a Watcher and the penalties for breaking them. [[spoiler: When the Watcher's tribunal sentences him to death, he accepts it and evens turns down [=MacLeod's=] rescue.]]
* GangstaStyle
* HandicappedBadass: Joe Dawson has no legs and can still kick your ass all day long.
* HonorBeforeReason: In 'Judgment Day'.
* MrExposition
* {{Muggles}}
* PermaStubble
* SemperFi: Honorably discharged after losing his legs to a landmine in Vietnam.
* TheBartender: Owns his own blues bar.
* TheWatcher: Well, one of them.

!Friends and Allies of the Main Characters

[[folder: Darius]]

An ancient Immortal who was once a warlord, but after he defeated an ancient Immortal he changed his ways and renounced violence. He would spend much of his life to come living on holy ground so as to avoid the game, although some of his duties as a priest would have him leave the safety of holy ground. On one of these occasions, tending to the wounded and dead at Waterloo, he would meet Duncan and give Duncan some food for thought regarding continuing to spend his life as soldier through all the centuries.

Unfortunately he became a target for James Horton and the rogue Watchers who decided to wipe out Immortals entirely, and was murdered in his church by them.

* ActualPacifist: Darius no longer carried a sword and rarely if ever left holy ground. He was effectively out of the Game and never fought.
* TheAtoner: He used to be a warlord. He was atoning for his sins.
* BadassPreacher: A pious preacher with fighting skills.
* RealLifeWritesThePlot: Werner Stoker, the actor who played him died during the filming.
* RetiredBadass: He used to be a Badass warlord. He lived a peaceful life in retirement.
* TheOlderImmortal: Grayson is referred to as one of the few remaining ancient Immortals. Darius is implied to have been Grayson's teacher, and thus would almost certainly have some years on him. One of the ExpandedUniverse novels makes this explicit.

[[folder: Hugh Fitzcairn]]

An old friend of Duncan's, Hugh has often been an adventurer, rogue, and all around lady's man. The two have shared many adventures and travelled together throughout the centuries, and remain friend in the present. In the modern day, Hugh works as a well regarded chef.

* TheCasanova: Hugh was a womanizer for centuries. When married in the 1920s, he cheated on his mortal wife frequently.
* DistressedDude: Duncan has had to save him from danger on a number of occasions.
* FriendlyTarget: He was targeted and killed by Kalas because of being Duncan's friend.
* LadyKillerInLove: Believed himself to be this with Naomi. Whether this romance would have gone differently is impossible to know, but he takes the loss of their life together extremely hard.
* RichesToRags: In the 1920s, Hugh was a wealthy man. He lost everything in the Wall Street Crash of 1929.
* SupremeChef: He'd have to be to hold his own at Le Cordon Bleu.
* UndeadTaxExemption: Averted. Hugh has not acclimated to changes in technology, especially computers, all that well. He needs Duncan to help him forge documents and certifications, otherwise he wouldn't be able to keep up the act for long.
* YourCheatingHeart: He was an unfaithful husband.

[[folder: Cassandra]]

An ancient Immortal who was born sometime during the Bronze Age, she had just discovered a talent for healing when her village was attacked by the Four Horsemen and her people slaughtered. She awoke from her first death in the power of the Horseman called Death, [[spoiler:aka Methos]] who explained Immortality to her and told her that she would live only as long as she served and amused him. Regardless, the two grew surprisingly and genuinely close until the cruel Kronos demanded that [[spoiler:Methos]] share her with him as a spoil of war, as the Horsemen shared all their other spoils. She was horrified when he agreed, and she fought Kronos and managed to mortally wound him and flee. [[spoiler:Methos]] watched her go and made no effort to stop her, hinting that he wanted her to escape the life she was trapped in.

For many years afterward she escaped notice, learning further skills as a healer, control of a CompellingVoice, as well as developing visions of the future. After her student Roland Kantos turned on her after learning some of her talents, she became obsessed with a prophecy that told of his defeat, and spent decades living in the wild highlands of Scotland, where she believed the one who would fulfill the prophecy to defeat Kantos would be born. She encountered Duncan there as a young boy, and came to believe the prophecy was about him. She encountered him again many years later, and helped him both against Kantos and later the reunited Horsemen.

* CompellingVoice: Her biggest talent.
* TheMedic: Shortly before her village was destroyed by the Horsemen and she learned about being Immortal, she showed an unusual skill for healing others.
* [[NonActionGuy Non Action Immortal]]: Despite her longevity, she's not much of a fighter, and seems reliant on her CompellingVoice to do most of the work for her.
* SexyMentor: Is one for Duncan.
* SolitarySorceress: In the past, including when she encountered Duncan as a boy.
* StockholmSyndrome: Developed it towards [[spoiler:Methos]] during his Four Horsemen days, and it is implied that he in turn developed a sort of LimaSyndrome to her eventually. When he agreed to give her to Kronos, however, she was outraged and came to hate him in the many years since. When she sees him again in the present day, she immediately tries to attack him.
* TheOlderImmortal: One of the oldest living Immortals at the start of the show, at almost three thousand.
* VoluntaryShapeshifting: Her encounter with a young Duncan implies she's capable of this, but never confirms it.
* TheWorfBarrage: Her CompellingVoice gets used on Kantos, who knows how to block it due to being a master of it himself, and Kronos, who is old/badass/sociopathic enough to simply shake it off.

[[folder: Charlie De Salvo]]

A retired Navy SEAL turned dojo master, Charlie became friends with Duncan, and facing prolonged financial difficulties eventually sold his dojo to Duncan, although Duncan requested that Charlie remain there as a manager and martial arts sensei. Charlie soon became very suspicious of the strange circumstances that always followed Duncan, especially after he witnessed Duncan be shot in a way that should have been fatal but show no signs of injury soon afterward.

Eventually he fell for a Belkan revolutionary named Mara and left Seacouver to help her with her rebellion, but her group was decimated when they were sold faulty weapons by the Immortal arms dealer Andrew Cord, and Mara was killed by Cord when she confronted him afterward. Charlie followed Cord back to Seacouver intent on revenge, but because Duncan had never told him about Immortals he didn't know how to kill Cord for good, and was mortally wounded in a knife fight with Cord.

* BackForTheDead: After returning from being put on a bus, he comes back for one episode to reveal that he and Mara were set up by Immortal ArmsDealer Andrew Cord, who intentionally sold them defective arms, then killed Mara when she confronted him about it. Charlie vowed to kill Cord for this, but not knowing about Immortals, he was doomed from the start.
* DarkAndTroubledPast: Charlie grew up as a mixed race kid in a tough neighborhood who had to fight off kids from both sides growing up, then he went into military.
* DeadpanSnarker: At times, Perhaps most notably when Xavier St. Cloud with mock politeness, calls himself an old friend of Duncan's and then has his mercenaries shoot the dojo to pieces.
-->'''Charlie:''' I don't think your "friend" likes you.
* DefeatMeansFriendship: With [=MacLeod=].
* ElitesAreMoreGlamorous: Spent 12 years in the military, during which time he became a Navy SEAL.
* LockedOutOfTheLoop: Regarding Immortals.He knows something deeply weird is going on with [=MacLeod=], but he doesn't learn about it until he's in his dying moments.
* MixedAncestry: Half African-American, half Italian.
* PutOnABus: After falling for Mara, he leaves Seacouver to aid her with her revolution.

[[folder: Carl Robinson]]

A black man born in American South during the 1800s, he lived as a slave until his master killed him with the suspicion that Carl had gotten the master's daughter pregnant. After reviving Carl escaped and learned about Immortality. He encountered Duncan in the 1920s when Duncan saved him from being lynched by the KKK, and the two remained friends for years afterward. Carl had dreams of pitching in Major League Baseball, and during the 50s played in the Negro Leagues. In the show's present he had succeeded in becoming a minor league pitcher, but he became the subject of a manhunt when he was spotted in the aftermath of fighting an Immortal, and had to leave the country after his death was faked with the help of his first teacher, now an FBI Agent.

[[folder:Anne Lindsey]]

A surgeon who became Duncan's first serious love interest after the death of Tessa. He resisted telling her about Immortals for a long time, until after she saw him "die" during a fight with Kalas. By the time she encountered him again and he informed her about Immortals she had become pregnant, and although both were initially willing to give their relationship a chance to continue, further encounters with Immortals left her shaken and deciding she couldn't continue that life.

* BrainyBrunette
* FriendlyTarget: Kalas attempted to destroy her life and professional reputation by forging orders in her handwriting and with her signature that led to the deaths of patients.
* IJustWantMyBelovedToBeHappy: Duncan eventually came to this point of view about her.

[[folder:Kol'Tek/Jim Coltec]]

A Native American shaman and medicine man known for being able to absorb the anger or evil from others to give them peace. He was also known for going out of his way to hunt down evil Immortals, and eventually killed so many of them that the Quickenings from so many evil Immortals became a Dark Quickening and changed him, making him as evil as they had been. Duncan attempted to help him but was unable to bring him to his senses and had to kill him, which in turn caused Duncan to absorb the Dark Quickening and undergo a similar experience.

* DemonicPossession: After the Dark Quickening, he starts to cycle through the personalities of the Immortals he has killed over the years, all of whom were extremely bad guys.
* EvilCostumeSwitch: Swaps his brown fringed jacket for Kant's black leather.
* EvilIsHammy
* GoodIsNotSoft: Dawson says Coltec is "as close as an Immortal gets to being a saint", and Duncan clearly values his friendship. He's also a stone cold BadAss who makes a point of hunting evil Immortals.
* HeroOfAnotherStory: He seems to have [[WanderingTheEarth wandered for a while]], helping others and killing evil Immortals as he encountered them.
* MagicalNativeAmerican
* MoreThanMindControl: He claims this, but it's never confirmed either way.
* NiceGuy
* OffscreenMomentOfAwesome: His duels with Korland and Kant each last less than a minute, implying that either they're both terrible fighters or Coltec is an excellent one. Considering that [=MacLeod=] has a very difficult time beating him, it's probably safe to lean towards the latter option.
* OOCIsSeriousBusiness
* RetiredBadass: Unlike Darius, he still lives in the world, but hasn't taken a head in years until he runs into Harry Kant.
* TheOlderImmortal: He's about twice as old as [=MacLeod=].
* TheStoic: Doesn't get riled, even during Immortal duels.

[[folder: Rebecca Horne]]

Amanda's first teacher and mentor. She appeared in an episode where Luther, a pupil of hers who had turned evil, was attempting to claim a mystic stone in her possession, which legend said could make an Immortal invincible. Rebecca had been giving pieces of the stone to her various students, whom Luther had hunted down and defeated to claim their shards. She tried to face Luther, but he took her mortal husband hostage and forced her to give up her own life to save his.


[[folder: May-Ling Shen]]

A teacher of Duncan's during his travels in China, she showed him some finer points of both armed and unarmed combat. Although a highly skilled fighter whose students were practically awed by her, she was killed by the much younger Immortal Michael Christian, whose Watcher had fallen in love with him and helped him ambush other Immortals at times when they were unarmed or helpless.

* LadyOfWar
* SexyMentor: To Mac.

[[folder:Sean Burns]]

A former Irish monk who centuries later found his true calling in psychology and the healing of minds, Burns was an old acquaintance of [=MacLeod=] and numerous other Immortals that he helped throughout the years, including Stephen Keane. When Duncan was suffering from [[NotHimself the Dark Quickening]], Burns offered his help to Duncan, but Duncan killed his former friend instead. Ironically, the Quickening from Burns gave Duncan just enough control over the Dark Quickening to seek out a more permanent cure.

* NonActionGuy
* TheShrink

[[folder: Marcus Constantine]]

A former Roman general who repented violence and war after encountering Darius, and has been living his life in relative peace since.

[[folder: Graham Ashe]]

A friend of Duncan when Duncan was fresh to Immortality, he had a reputation as a great swordsman but was in truth far more interested in the arts and knowledge. His head was taken by Haresh Clay, a prominent head hunter who while not evil was a merciless warrior who sought out powerful enemies to defeat in order to gain their power and win The Game.

!Major & Recurring Villains

[[folder: Xavier St. Cloud]]

-->''"I'm just trying to earn a few francs. After all, a man's got to live."''

A sociopathic thief and murderer with a taste for expensive clothes and food, Xavier is a dangerously ruthless Immortal. Duncan recognized his MO for using lethal gas in his robberies and foiled one such attempt, when the two fought Duncan cut off one of his arms but Xavier was able to escape. He would return later, having allied with James Horton to eliminate Immortals and using mercenaries to wound his foes until they were helpless and easy prey for him to finish.

* BadassDecay: [InUniverse] In the past, Xavier was a highly feared Immortal who played the game seriously, seeking out and challenging other Immortals with a reputation as skilled fighters to kill them and take their powers. At this time, a fight against him was considered more or less a death sentence. At some point over the centuries as the Game showed no signs of coming to an end he became disillusioned with it and instead turned his focus to stealing in order to support a lavish and hedonistic lifestyle. As a result either his sword skills suffered or it gave old opponents like [=MacLeod=] a chance to surpass him.
* BigBadDuumvirate: With Horton for two episodes.
* CombatPragmatist: One of the biggest in the series. Perfectly happy to use poison gas or mortal gunmen to incapacitate other Immortals.
* FauxAffablyEvil: Extremely polite and rarely raises his voice. He's also a nasty piece of work, and is seen using [[DeadlyGas chemical weapons]] to commit robberies.
* GentlemanThief: Played with. Sure, he's classy, suave, and has great taste, but his M.O. tends to involve murdering everyone in the store he's robbing.
* HandicappedBadass: Losing a hand doesn't make him any less dangerous. He's still a skillful fighter and we see him use his prosthetic as an additional weapon in at least one fight.
* ManOfWealthAndTaste: When [=MacLeod=] is trying to trace Xavier, his description is basically "elegantly-dressed black man with one hand", because, regardless of the country or time period, the man is dressed to the nines every time we see him. His love of a particular (and particularly expensive) type of caviar is what enables Duncan to finally locate him, whereupon we find that he's living in a huge villa.
* MentorOccupationalHazard: Has been both the cause and recipient of this. Murders one of [=MacLeod's=] mentors, and when Mac returns the favor years later, one of Xavier's own students vows revenge.
* RetCon: In his first appearance, he was just a thief and the only backstory or past association with [=MacLeod=] was when Duncan was a random victim of Xavier's gas during a WWI theft. Further backstory and his past was added when he appeared in additional episodes.
* VillainForgotToLevelGrind: In past centuries he was considered one of the most dangerous Immortals in the world, but he's not anymore.
* YouHaveOutlivedYourUsefulness: In his appearance he convinces a mortal helper that the gas is merely knockout gas and that the man can safely take off his gas mask. When the man does, Xavier laughs and essentially says that now he won't need to split the proceeds of the robbery.

[[folder: James Horton]]

A Watcher gone rogue, Horton has become convinced that most Immortals are evil and even those that aren't are too dangerous to the future of humanity to be allowed to live. He has secretly converted a fairly large portion of the organization to his view, and has turned their considerable knowledge and resources to hunting down and eliminating all Immortals.

* BigBad: In Season 2.
* CrazyPrepared: During his second encounter with [=MacLeod=] we see he has an escape boat prepared and wears a bulletproof vest.
* FantasticRacism: He believed immortals were a crime against God, and that the prize for being the last was the domination of humanity. So he sought to hunt down and kill every last one. WordOfGod says he became this way after being The Kurgan's watcher and forced to document his atrocities.
* FinalSolution: Thinks that he needs to kill all Immortals in order to prevent them from ruling or killing mortals.
* KnightTemplar: Wants to save humanity by [[FinalSolution eliminating all Immortals]].
* ManipulativeBastard: The whole time he was hunting immortals, he and his men lead double lives as part of the watchers(who took a vow to only observe immortals and never interfere with them) and used the watchers resources to assist in his mission.
* MoralMyopia: When he and his Watchers kill people for absolutely no good reason, it's okay, but when Immortals do it...
* NotQuiteDead: [[spoiler:Several times.]]
* ScrewThisImOuttaHere: He retreats the moment he learns that [=MacLeod=] has tracked Xavier and himself to the stables.
* TheWatcher: The renegade one.

[[folder: Kalas]]

Duncan first encountered him centuries ago, living as a monk at a monastery with several Immortals there, and which acted as a refuge to Immortals who wished to have a place of safety to live away from The Game for a time. He was a scribe, exactly making copies of The Bible, and a great singer in the monastery's chorus. He was also preying on Immortals who came there for peace, as he would surprise them as they were leaving the grounds and take their heads. When Duncan caught him at this Kalas was expelled. The two encountered each other several times again, with Kalas proving himself a thoroughly nasty piece of work each time, and trying to ruin not just Duncan's life but that of everyone around him for revenge, which only intensified after Duncan slashes his throat and ruined his remarkable singing voice.

During the course of the third season he catches the Watcher assigned to him and tortures the man into telling him about the Watchers. First he attempts to use Watcher information to take the head of Methos, believing that with the Quickening of such an ancient Immortal he'd be unstoppable. He also attempts to ruin the lives of Duncan's friends and allies by doing such things as planting drugs in Joe's bar and calling the authorities, endangerng the medical license of Dr. Lindsey, framing Hugh Fitzcairn for murder, (and later taking Fitz' head) threatening to expose Watcher information on both Immortals and Watchers, etc.

* {{Badass}}: He actually ''beats'' [=MacLeod=] in their first fight. In present day, Dawson warns [=MacLeod=] that Kalas is as good as he is, maybe better.
* BeardOfEvil
* BeenThereShapedHistory: Implied in the '20s when he mentions that fellow opera star Enrico Caruso is dying in New York. "People say he was poisoned."
* BigBad: In Season 3.
* DevilInPlainSight: Duncan was the only one to suspect Kalas' true nature during his stay at the monastery.
* DisproportionateRetribution: [=MacLeod=] got him kicked out of a monastery and ruined his singing voice, which causes him to go after anyone [=MacLeod=] is close to.
* EngineeredPublicConfession: When Duncan confronts him at the monastery Kalas says no one will believe Duncan, since Duncan is just a visitor passing through and Kalas is a founder of the monastery. Too bad Duncan had the forethought to have the other cofounder standing right behind a nearby column when he said that...
* EvilAllAlong: Was using the safety of holy ground to get desperate immortals to drop their guards so he could kill them more easily when they left the refuge.
* EvilSoundsRaspy: [=MacLeod=] cut him [[IndyPloy with a piece of glass during their duel]], ruining his beautiful tenor voice.
* GutturalGrowler: Had his throat slashed by Mac in the '20s. He survived; his singing career did not.
* ItsAllAboutMe: Seems to value his singing voice much more highly than the lives of other people.
* ManipulativeBastard: Kept the head of the monastery, Paul, in the dark about his nature for hundreds of years, all the while murdering the immortals that left their 'refuge'. Also near-successfully framed both Richie and Anne in order to get back at Duncan and keep him off-balance.
* {{Narcissist}}: He wants to destroy Duncan for getting him kicked out of the monastery where he felt his vocal talents were most appreciated and destroying his world-class singing voice. He doesn't seem to care that Macleod only did these things because [[NeverMyFault he was either killing people or trying to kill him at the time]]. He is also implied to have poisoned Caruso, presumably out of jealous spite.
* RevengeByProxy: He would kill or frame anyone who is somehow related to [=MacLeod=], and he does kill several Immortals who are friendly with [=MacLeod=], including [[spoiler:Hugh Fitzcairn]].
* SadisticChoice: Tells [=MacLeod=] during the last episode of season three that if he doesn't [[spoiler: put down his sword and let Kalas kill him, the Watcher database would be emailed to newspapers around the world, possibly destroying the lives of Immortals and Watchers alike.]]
* [[SinisterMinister Sinister Monk]] He lived in a monastery where immortals took refuge when weary of the game, and killed out of practice immortals as they left holy ground. The head priest banished him when Duncan caught him in the act.
* WickedCultured: Even after his singing career is brought to an end, he still listens to opera and is briefly seen operating a jazz club in Paris.

[[folder: Kenny]]

An Immortal whose Immortality was triggered when he was still a child, forever trapping him in the body of an 8 year old. He was discovered as a youngster by Amanda, who looked after him and trained him to help her in her operations as a thief, but the two were separated when Amanda was caught and hung for thievery. Afterward, he developed a specialty of letting Immortals take him in, thinking him just a child new to being Immortal, learning from them, and then taking their head when the chance first appeared. Doing this has let him survive ''centuries'', despite his lack of combat ability and being helpless in the face an Immortal challenge.

* CombatPragmatist: Out of necessity. His targets are unsuspecting, and he attacks from behind.
* CreepyChild: He looks 8, but he's really closer to ''800''. As a result he has some completely unchildlike motivation hiding below the surface.
* KarmaHoudini: He has exploited and murdered numerous mortals and Immortals over the years and puts [=MacLeod=] in serious danger. His only punishment is having Amanda sever their relationship.
* WoundedGazelleGambit: It's his specialty. He pretends to be a new Immortal, gets another Immortal to take him in and shelter the helpless child, then kills them when he has a chance.

[[folder: Kronos]]

The leader of the Four Horseman, a band of Immortals that ravaged the world in the Bronze Age. Cruel, remorseless, and obsessed with holding power over the world, he has continued to ride with outlaws and brigands through the ages, but thinks of it all as a pale imitation of his days as a Horseman. Duncan briefly encountered him in the WildWest as the eader of one such band, and in the present he's eager to reunite the Horsemen and use a deadly biological weapon to bring about a new age of chaos that they can control.

* {{Badass}}: Was the leader of the [[HorsemenOfTheApocalypse Four Horsemen of the Apocalypse]], whose reign of terror was implied to have lasted for at least a millennium.

* BeardOfEvil: Back in TheWildWest.
* BloodBrothers: Implied to have this relationship with [[spoiler: Methos]] and the other Horsemen.
* BloodKnight: Seems to have an excessive love for combat, death and destruction, fittingly for someone who's the historical basis for one of the [[HorsemenOfTheApocalypse Four Horsemen]] [[TheEndOfTheWorldAsWeKnowIt of the Apocalypse.]]
* CombatPragmatist: The pommel and handguard of his sword are decorated with short spikes for additional damage during close combat.
* GoodScarsEvilScars: Has an impressive one on the right side of his face.
* HellbentForLeather: Favors a leather jacket in the modern day. The production crew gifted it to actor Valentine Pelka after shooting.
* HorsemenOfTheApocalypse: Was the leader of the group that inspired the Horsemen of the Bible.
* ManipulativeBastard: [[TheCorrupter Skillfully manipulates]] [[GuileHero Methos]] of all people, at least for a while, though reminding Methos how much he [[spoiler: [[RetiredMonster sometimes still missed being Death]]]] [[MasterActor didn't work]] [[TheAtoner the way he wanted it to]].
* TheOlderImmortal: Was making trouble during the Bronze Age in Mesopotamia, so at least over three thousand years old, and possibly a fair bit older than that.
* TheSociopath: Lacks empathy, cruelly manipulates even someone he calls a brother, and definitely has the grandiose sense of self-worth necessary for the trope.
--> Kronos (as he's [[spoiler: losing a battle to Macleod)]]: "I am the end of time!"

[[folder: Caspian]]

A member of the Four Horsemen, and a deranged psychopath who admired Kronos but didn't get along very well with the other members.

* BashBrothers: Downplayed, as he seems to be the troublemaker of the Horsemen, but he's still this with the group.
* BeardOfEvil
* CombatPragmatist: Happily uses multiple weapons. His sword has been heavily customized to feature a harpoon-like barb on the blade and a sharpened hand guard. He'd have no problem killing [=MacLeod=] while he was recovering from a Quickening.
* DualWielding: Gleefully attacks [=MacLeod=] with a sword and knife.
* ImAHumanitarian: "They found parts in his basement, in his garden, in his freezer."

* BloodKnight: More than any of the Horsemen, he relished combat and disapproves of Kronos' methods of using biological warfare.
-->I don't like this killing from a distance. I like to feel my axe in my hands. Look into my enemy's eyes before I strike.
* CombatPragmatist: "You kill one of us, the other takes your head while you're down."
* DumbIsGood: Well, he's both the dumbest and ''least'' evil of the Horsemen. Although that's DamningWithFaintPraise.
* DumbMuscle
* EvilSoundsDeep
* PsychopathicManchild: A bloodthirsty warrior who relishes killing in combat and has been longing to ride with the Horsemen again for thousands of years, he also deeply disappointed when he learns he won't be able to keep one of Kronos' test monkeys as a pet.
* RetiredMonster: He seems to have given up marauding by present day, but jumps at the chance once Kronos starts getting the band back together.
* StoutStrength

[[folder: Ahriman]]

A demon (literally) who appears on Earth every few thousand year, he manipulates normal people and Immortals alike through the use of mind games and illusions, seeking to break them or have them commit atrocities while under his influence.

A former pupil of Darius' from the days when Darius was a fearsome warlord, he's a dangerous and feared Immortal who has remained fascinated with warfare since he was young and continues to be in the current day, utterly rejecting Darius' message of peace.

* ArmsDealer
* BeenThereShapedHistory: Some fans take Grayson's speech about gunpowder ("It took someone with vision") to mean that he invented the stuff, or at least realized/began working on the military applications of it, but it's never stated either way.

* CoolSword: A Kris broadsword.

* RevengeByProxy
* WarForFunAndProfit: Part and parcel of being an arms dealer.

* WorthyOpponent: "Worthy" may be an overstatement, but he does hold Duncan in a certain regard and seems to respect his fighting abilities.
* YearsTooEarly: Claims that Duncan needs another century or so of practice and taking heads to have a chance to beat him. While he comes close to defeating Duncan, he turns out to be wrong about that.

* {{Camp}}
* CombatPragmatist: Kuyler tries to gain an advantage on Duncan by luring Duncan to a hideout with a mannequin for each victim of his assassinations. He dresses and wears makeup so he will blend right in with those mannequins, and then turns the encounter with Duncan into a cat and mouse game.
* EnemyMime
* EvilHasABadSenseOfHumor: Kuyler's hideout has a large room filled with mannequins, and he blends into them very well when wearing his makeup. We first see him use this camouflage to scare one of his informants. "I'm sorry, I think it's very funny."

The newly Immortal Richie intervened to protect the man, and the attempt failed and caused the death of Devlin's current mortal husband. She comes after Richie for revenge, and thanks to Duncan's training he gets the best of her but is unable to kill her.

[[folder: Kanwulf]]

A viking raider who kept working as a raider and pirate long after the end of the Viking Age, he mortally wounded Duncan's adoptive father Ian [=MacLeod=] in an attack on [=MacLeod=] lands shortly after Duncan was exiled following his first death. Duncan vowed to avenge his father and sought out Kanwulf's band, and somehow succeeded in running Kanwulf through. Duncan had not yet had any teachers and knew nothing of Immortals, so he didn't know to finish Kanwulf off by beheading him. Believing that he had successfully avenged Ian, he took Kanwulf's battle axe and buried it beside Ian.

The axe was Kanwulf's most prized possession, and even in the show's present he still wanted it back, and to find it he murdered a priest being sent to the ancestral ands of Clan [=MacLeod=], assumed the man's identity, and began trying to dig up graves from the right era. Eventually, because he sold relics that were dug up and Duncan recognized one at an auction, Duncan came back to Scotland, and after returning the axe, the two engaged in a final duel.

Over the years he became more and more jaded and sure that the only place he could truly call home was the battlefield, and so served in many major wars, where his experiences only furthered his cynicism. He was a squadmate of a young Joe Dawson in Vietnam, and saved Dawson's life. In the present he's a black market arms dealer, and became a bitter enemy of Charlie [=DeSalvo=] when Cord intentionally sold the revolutionary group led by Charlie's lover Mara defective weapons, which got them slaughtered. To add onto things, when Mara confronted him he killed her, leading to a deadly grudge between Charlie and Cord. When Cord mortally wounded Charlie in a knife fight, Duncan challenged him for revenge afterwards.

* ArmsDealer: And in some cases, he will intentionally sell defective weapons to people.
* CombatPragmatist: Lures enemies into a base with tons of booby traps and other surprises. This also makes up for the fact that he's a soldier from the era where guns are the WeaponOfChoice rather than swords.
* EvilCounterpart: To Duncan's friend Carl Robinson, (who is also a black man that was nearly as embittered as Cord by the racism of America, but was eventually able to let that go without JumpingOffTheSlipperySlope or crossing the MoralEventHorizon) and to Charlie [=DeSalvo=]. (Both minorities in America who pursued a life in the military and proved to be unable to leave combat behind them.)
* EvilFormerFriend: To Joe Dawson.
* FallenHero: Cord served with distinction in numerous wars, and saved Joe's life in Vietnam, but he became jaded, bitter, and nihilistic over the years. Now all he cares about is money and himself.
* HistoricalInJoke: Supplemental materials claim his first Immortal teacher was Robert Gould Shaw, the Colonel in charge of [[https://en.wikipedia.org/wiki/54th_Massachusetts_Infantry_Regiment 54th Massachusetts Regiment]], a regiment made of black men fighting for the north in the Civil War.
* ILied: Promises not to kill Charlie for the sake of Joe... and then kills Charlie in a knife fight anyway.
* TheNicknamer: Joe is "boy scout".
* IOweYouMyLife: Dawson feels this way toward Cord, as Cord went to extraordinary lengths to save Joe in Vietnam.
* SemperFi
* ThenLetMeBeEvil: Cord's experiences with racism and persecution crushed the idealism and optimism he had when young, and led to him adopting a selfish, nihilistic philosophy of valuing only money and getting ahead.

* CanineCompanion: Three Rottweilers.
* CombatPragmatist: Uses his dogs to attack other Immortals, wearing them down for an easy kill.

[[folder: Terence Kincaid]]

An Immortal who has worked mostly a sailor and merchant on the seas. He and [=MacLeod=] were once on friendly terms and sailed together, but that relationship soured when Duncan saw that Kincaid had little regard for the lives of the sailors who served under him, valuing profit far more. He eventually pushed his sailors too far, and when he refused to return to port for food to feed his undersupplied crew, they mutinied. To keep the secret of Kincaid's immortality, Duncan convinced the crew to maroon him on a deserted island with little food or drinkable water, where Kincaid did not have a pleasant time of it, to put things mildly. In the present he was attempting to get an easy Quickening by killing Kenny when [=MacLeod=] stepped in to protected the childlike Immortal, but Kenny then schemed with him to attempt to take down [=MacLeod=].

* AFateWorseThanDeath: When his sailors mutinied, Duncan saved his life by getting them to maroon Kincaid on a deserted island without food or water. Kincaid was trapped on that island, dying constantly of starvation and thirst until another ship passed by... nearly 100 years later.
* {{Greed}}: In his own words "I will not lose 100,000 pounds for the sake of a few lives".
* MoralMyopia: Duncan marooning him on an island where he suffered horribly from hunger and starvation is an unforgivable affront to him. Him risking the starvation of his entire crew is a small price to pay for a profit of 100,000 pounds and to keep to his reputation for timely shipping.
* TheNeidermeyer: Was the captain of a merchant ship during the Sailing Age, but only cared about profits and keeping to schedule, which eventually drove his starving crew to the brink of mutiny. Kincaid pushed them over the brink by shooting the most vocal of his critics.
* ReducedToRatburgers: At first he fed himself on the few things living on the island, like toads and snakes, but eventually was catching ''flies'' as his sole form of sustenance.

[[folder: Col. Simon Killian]]
* ColonelKilgore: He ordered an attack to go forward after being informed of the WWI Armistice because he didn't believe that anything but a military victory could bring peace.
* AFateWorseThanDeath: Spent seventy years in a mental asylum thanks to Duncan
* {{Revenge}}: Plans to keep Duncan locked in a cell for the next seventy years.
* SanitySlippage: He's more than a little... off... when he finally gets out of the asylum. And he wasn't wrapped particularly tightly to begin with.
* VillainHasAPoint: During his court martial rant, the obviously unstable Killian correctly predicts that unless Germany suffers a crushing military defeat, [[WorldWarII another war between the Allies and Germany will be inevitable]].

[[folder: Kristin]]

A former lover of Duncan's from when he was a young Immortal, she is forever obsessed with her beauty and fears any loss of it... and hates anyone she thinks might be more beautiful than her or stealing the attention of men she has her eye on, When she shows up in the present she's the head of an international modeling agency, and she begins working her charms on Richie before Duncan can warn him about her.

* BadBoss[=/=]IWillPunishYourFriendForYourFailure: When Duncan began falling for the artist she hired to do a portrait of him, she murdered said artist and proclaimed it an accident. She tries to do something very similar to Maria, a model of hers that Richie asks her to release from Maria's contract due to her certainty that Maria must be a rival for Richie's affections. In both case it's about hurting the person who "betrayed" her by hurting people close to them.
* EvilOnlyHasToWinOnce: Methos tries to get Duncan to kill her by saying that yes, she's obviously no match for him in a fight, but if he keeps letting her walk away and have another chance, someday some freak occurence will happen and she'll take his head. Not to mention how many people she might hurt in the meantime.
-->'''Methos:''' Do you know how many Immortals she's killed? Do you want a list?\\
'''Duncan:''' Okay, you've made your point.\\
'''Methos:''' Have I? One day, she's going to ''kill'' you.\\
'''Duncan:''' She's tried already.\\
'''Methos:''' You're better with a blade than her, yes. You're stronger than her, yes. But if you keep letting her walk away, one day she will get lucky and take your head.

While under the influence of the Dark Quickening, Duncan murders Sean Burns and comes close to doing the same to Richie. Burn's death will lead to Steven Keane renewing his promise of revenge against Duncan.

* BlueAndOrangeMorality: Regarding the Game. He considers the challenges a godly purpose, regardless of who was being fought, whether they were a good or bad person, etc. He defeated a young pupil of Duncan's in the past who had repeatedly challenged him, and at first Duncan was furious as Case was already an old Immortal while the pupil was brand new to the game and argued that Case should have refused the challenge and spared the young man, but Duncan came to realize that Case wasn't evil, or a bully picking on an Immortal who couldn't fight back effectively, he simply had a very different way of approaching the Game and life itself.

An amateur magician and complete newcomer to being Immortal, Danny has made Immortality part of his stage act, by being shot on stage and then reviving in front of the crowd.

-->''"Do you know what it's like to have a friend for nine hundred years, [=MacLeod=]? I've known him longer than you've been alive. He was my squire and my companion on one hundred campaigns and five continents. Now he is gone."''

An Immortal who played the Game by purposefully seeking out other powerful fighters and taking their heads in a bid to become the strongest around, Clay was longtime friends with Carter Wellan, who he regarded as something of a squire and a longtime friend. When Richie and Wellan fought and Richie won, Clay came to avenge his old friend. Duncan, knowing Richie would be no match for Clay, first tried to talk Clay out of revenge and then faced him in Richie's place.

[[folder: Steven Keane]]

A morally upstanding but inflexible and stubborn Immortal who has only encountered Duncan during Duncan's more morally grey or darker moments. They first ran into each other sometime after the Battle of Culloden, where the English completely crushed the Jacobite rebellion in Scotland. A furious and broken Duncan responded by going on a self-appointed mission to assassinate the various English leaders who won the battle and repressed the Scots afterward. One of those men was a friend of Keane. Keane thought Duncan was there to challenge him, but instead Duncan casually shot Keane and killed his friend before Keane could recover. A furious Keane attempted to pursue [=MacLeod=] for decades afterwards, but was eventually talked out of revenge by Sean Burns who got Keane to put aside his usual BlackAndWhiteMorality and convince him that Duncan wasn't an evil man. When he later hears that Duncan killed Burns in the show's present, (not knowing about the Dark Quickening or how it affected Duncan) this time Keane does come for revenge, and won't let anyone talk him out of it.

* AvengingTheVillain: [[GrayAndGreyMorality The term "villain" may be somewhat murky]], but one of the reasons he holds a grudge against Duncan is because in the wake of a failed Scottish rebellion Duncan murdered a mortal friend of Keane's who crushed the Scots.
-->'''Methos:''' Do you remember what happened after [[CurbStompBattle Culloden]]?\\
'''Duncan:''' [Looks away, then back] Yeah. I went after innocent men and slaughtered them.\\
'''Methos:''' No, that's how Keane tells it. I want to know how you remember it. Because they weren't innocent, were they? There were murderers. They were the English bastards who had destroyed your people, and they deserved to die, all of them.
* BlackAndWhiteInsanity: According to Methos, this is what Keane's worldview is. (And Duncan's too.)
* CycleOfRevenge: In the past, Sean Burns talked him out of this by convincing him the war and its aftermath was essentially a case of GreyAndGrayMorality. In the present, he rejects any attempts by Amanda and Methos to talk him out of a duel, despite the fact that, as Amanda points out, the friends of each man will probably just get caught in a never ending attempt to avenge their loved ones if either he or Duncan dies in a duel.
* TheDandy[=/=]FashionVictimVillain: Keane likes his clothes, and he seems to go nowhere in the modern day without a suit and tie on, but he seems averse to wearing muted colors. His first run in with Amanda features him wearing a red suit and bright red, fur-trimmed overcoat. It's just as garish as it sounds. Over the course of the episode his suits calm down a bit, but his shirts and ties remain very bright.
* HeroAntagonist: He's essentially a mirror image of [=MacLeod=], who comes looking to kill Duncan for the exact same sort of reasons Duncan would kill an evil Immortal. Duncan himself points this out by saying that Keane is judging him on similar criteria to how Duncan has judged any number of Immortals.
* HonorBeforeReason[=/=]RevengeBeforeReason: Nothing can get him to back off from fighting Duncan, no matter what. Although he ''was'' talked out of it in the past by Sean Burns, but [=MacLeod=] killing Burns under the effects of the Dark Quickening was the final straw for Keane.
* IGaveMyWord: Swore to his friend's family that he would avenge their father's death and spent 30 years hunting [=MacLeod=] around the world, but always a step behind. Sean Burns points out that Keane would have done a lot more good if he'd spent those 30 years helping the family instead of wasting it seeking revenge.
* InterestingSituationDuel: In a way, he presents one for Duncan. Both Methos and Amanda are very confident Duncan could take Keane under normal circumstances, but with Duncan's mind clouded, distracted, and burdened by his own guilt, that creates an element of doubt for them that makes them worry about the outcome of the fight.
* NiceGuy: Amanda first encounters him at a club he owns, and the two have a friendly and amiable chat, until Keane starts asking if she's ever heard of someone named Duncan [=MacLeod=].
* NotSoDifferent: [=MacLeod=] and Methos both talk about the fact that Keane is in some ways a mirror image of Duncan, and Amanda tries to convince Keane of this, but Keane has only seen the worst in Duncan and hotly denies it.
* TrialByCombat Duncan eventually comes to see their duel as a form of this.
* UnknownRival: After their first encounter he spent 30 years chasing Duncan around the globe but never actually encountered Duncan because Duncan kept moving on. He shows up in the present with a fresh grudge and filled to the brim with righteous anger at Duncan, but to Duncan Keane was just a random guy he encountered for a few seconds 200 years ago.

-->''"I have no hope. No dreams. No poetry left. All I feel is this raging hunger. And all I hear is my own voice screaming my failure."''

{{Lord Byron}}. Yep, the historical one. He was a friend of Methos back in the day, and in the present is a rock musician with serious drug problems. He gets on the bad side of Duncan and Joe when he causes a young musician who was playing in Joe's club to overdose due to not having Byron's tolerance or Immortality to fall back on.

[[folder: The Messenger/"Methos"]]

An Immortal of unknown origin who is sick of The Game and combat among Immortals, he has been preaching a message of peace among Immortals and seeking to get them all to live in harmony and pool their knowledge and abilities for good. As part of his attempt to get other Immortals to listen to him, he claims to be Methos, in the hopes that his message will be given greater respect and weight coming from the legendary Oldest Immortal than from a random guy.

* ActualPacifist[=/=]SuicidalPacifism: The man walked it like he talked it.
* BadassPacifist: At one point he demonstrates that while he believes in peace and relies on his refusal to fight back to cause aggressive Immortal to back down, he's not incapable of self-defense.
* HorribleJudgeOfCharacter: Up to the moment of his death, he really thinks he's gotten through to Culbraith.
* {{Irony}}: The Messenger has no idea that he just encountered the real Methos when talking to that one snarky, cynical guy who wouldn't give a name.
* LivingIsMoreThanSurviving: He voices this opinion, claiming that Immortality isn't worthwhile if you don't try to do something with your life, as he is with trying to promote peace.
