Highlander the Series
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.
- Affectionate Nickname: Is referred to as "Mac" quite often by his friends.
- Badass Longcoat: Usually a black one. It's used to Handwave where he keeps his sword.
- Been There, Shaped History: 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.
- Big Brother Mentor: Duncan is a mentor to Richie, but often acts more like a cool big brother than a fatherly sort of mentor.
- Chronic Hero Syndrome: It doesn't matter if they're a complete stranger he's never met, Duncan will attempt to help them.
- Cultured Badass: He runs an antique store, can speak multiple languages, has excellent taste in wine and art, and is an expert swordsman.
- Dating Catwoman: He's the Batman to Amanda's Catwoman, but they do get along fairly well nonetheless.
- Devour the Dragon: 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.
- Hair Decorations: 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.
- Happily Adopted: 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.
- Heroic B.S.O.D.: In late seasons he starts getting hit with them, as a number of his friends die or drift away and he deals with the effects and aftereffects of the Dark Quickening.
- Honor Before Reason: Duncan has such a strong code of honour that he's walked into things he knows are traps rather than violate it.
- I Am X, Son of YI am Duncan MacLeod of the Clan MacLeod.
- Katanas Are Just Better: 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.
- Mr. Fanservice: He fights shirtless several times, and gives a full view of his backside at least once. (twice if you count Endgame)
- Multi-Melee Master: Proficient not only with a claymore and katana, but various other swords as well in addition to knives, axes and spears.
- My Country, Right or Wrong: He never let go of his Scottish heritage and has fought for his homeland at different times in history.
- Nice Guy: He routinely goes out of his way to help and be courteous to people for no other reason than because it's the right thing to do.
- Not Himself: The Dark Quickening.
- O.O.C. Is Serious Business: It is rather Downplayed, but...if Duncan ever starts smiling during an honest-to-goodness fight, you know you're in for a world of hurt.
- Perma-Stubble: Duncan almost always looks like it's been a couple of days since he used a razor.
- Real Men Love Jesus: Like Connor, is still astoundingly a devout Catholic in spite of being banished by the xenophobia of his Catholic kin.
- Slipknot Ponytail: Difficult fights often result in his distinctive ponytail coming out and his long hair hanging free
- The Coats Are Off: No matter the weather, Duncan always wear a long coat, (in order to hide his sword) but when there's a fight, the sword comes out and the coat gets ditched.
- The Stoic: At times in the opening season he actually had a more lighthearted approach and personality, but for the majority of the show's run, (especially after Tessa dies) Duncan emotes very little and meets events calmly.
- Warrior Poet: Much like Connor, he is a patron for music, poetry, fine arts, not to mention wine and fine cooking.
- "Why would I tell the truth?"
- The Atoner: Downplayed. Claims not to feel guilt for his time as one of the 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.
- Badass Bookworm: 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 doing nothing but killing people and smashing things.
- Bi the Way: 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 was no longer that kind of man.
- Big Brother Mentor: To Duncan, when Duncan will actually listen.
- Broken Pedestal: When Duncan found out the atrocities he committed as one of the Four HorsemenMethos: 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! Death. Death on a horse! When mothers warned their children that the monster would get them, that monster was me. I was the nightmare that kept them awake at night. Is that was you want to hear? Than the answer... is yes. Oh, yes.
- Combat Pragmatist/Fighting Dirty: Including tactics such as shooting Duncan in the back when Duncan is being a little too brash due to Honor Before Reason, or stabbing an opponent in the groin with a concealed dagger.
- Cool and Unusual Punishment: Against his better judgement, Methos allows Duncan to talk him into a fake fight to hopefully help rekindle the love between an Immortal couple (it makes sense in context). When the plan looks like it's going to backfire (thus actually endangering Methos), he retaliates by demanding Duncan's barge as the price of his involvement. Then after everything works out by the end of the episode, he decides he doesn't want the barge anymore and tosses Duncan the keys, making Duncan reflexively catch them and drop a $1,000,000 Ming vase he'd bought as a wedding present for the couple.Duncan: *sputtering in rage*Methos: (off-camera)*tosses Duncan a broom and dustpan*
- Dark and Troubled Past: see Broken Pedestal above
- Deadpan Snarker: Especially when someone implies his age should make him a wise man.
- Feeling Their Age: 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 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?
- The Fog of Ages/Time Abyss: 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."
- Good Is Not Nice: 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
- Guile Hero: One of the main reasons he's survived so long is because he's good at judging his opponents and outsmarting them.
- 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 Villain of the Week.)
- Heroic Self-Deprecation/Cowardly Lion: 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.
- Hidden in Plain Sight: Under the alias of Adam, he joins the Watchers, and gets himself assigned to tracking down... himself.
- Living Forever Is Awesome: While he has plenty of regrets, he also treasures continuing to live, have new experiences and new things to learn.
- Manipulative Bastard: Manages to pull of false Face–Heel Turn and plan the fall of the Horsemen from the inside
- Mayfly–December Romance: 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?
- Minored in Asskicking: Prefers not to fight at all in the present day, and will avoid challenges if he can, but 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.
- The Older Immortal: The oldest living man on earth at 5000+ years, even other immortals thought him a myth.
- Rebuilt Pedestal: At the end of the Four Horsemen arc, after helping Duncan bring down the other Horsemen by working against them from the inside, they begin to rekindle their friendship.
- Reluctant Warrior: He would prefer to stay out of the Game, but see Underestimating Badassery for what happens when someone tries to force the issue.
- Retired Badass: Or wants to be, anyway.
- Retired Monster: Even has one of the page quotes. However unlike the classic Retired Monster he is sorry and atones by destroying his comrades, who have not retired.
- Shoot the Dog: How he regards the idea of taking the head of Duncan's Psycho Ex-Girlfriend Kristin.Someone had to do it.
- Shrouded in Myth: Even among Immortals he's considered a urban legend.
- Time Abyss: Can't remember much before his first quickening.
- Trademark Favorite Food: Cheap beer.
- Trickster Mentor: To everyone. He never teaches a lesson straight out if he can help it.
- Underestimating Badassery:
- 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 Joe's daughter as bait. Said immortal thinks Methos is a weakling and a coward, and expects to easily beat him. Instead Methos 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 the Four Horsemen, took the moniker of Death.
- Also, in the bad timeline shown in the last episodes where Duncan was never born, Methos went on one hell of a Roaring Rampage of Revenge 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 teams back up with his old partner Kronos and begins leading the war against the Watchers. Their actions are described thusly: "They made the Russian Mafia look like choir boys."
- Would Hit a Girl: 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.
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.
- Battle Couple: She 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.

- Kill Steal: In her first appearance she decapitates a disarmed immortal seconds before Duncan would have killed him.
- Mama Bear: To Kenny, at least until she finds out what he really is.
- Overshadowed by Awesome: Amanda hangs around and is friends with Immortals like Duncan and 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.
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.
- Betty and Veronica: While Amanda is the much older, far more dangerous and glamorous thief, Tessa is sweet, stable and devoted.
- Damsel in Distress: Several villains kidnapped her to get to Duncan, preying on his desire to Always Save the Girl.
- Hair of Gold, Heart of Gold: She's sweet, artistic, non-violent, and feminine except when she threatens to burn off your face with a welding torch.
- Killed Off for Real: 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 come back stronger.
- The Lost Lenore: With her early death, she has more impact on Duncan's motivations dead than alive.
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.
- Ax-Crazy: After Duncan is afflicted by the Dark Quickening and tries to kill him, Richie decides to devote himself to The Game, and goes on a nationwide Immortal killing spree.
- Badass Adorable: He didn't take many heads on-screen, but the Immortals he did defeat included Mako (~700 years), Ivan Kristov (~400 years), and Carter Wellan (~1000 years). And he looks like this◊.
- Chronic Hero Syndrome: He developed a case almost as bad as Duncan's especially for any passing Damsel in Distress. The plots of a number of episodes are kickstarted by this trait.
- Dropped a Bridge on Him: Richie stumbles across Duncan while the latter is under the influence of Ahriman's hallucinations. Thinking that Richie is an enemy, Duncan decapitates him.
- Foster Kid: As immortals are all foundlings, Richie wound up in the foster system.

- Street Urchin: Starts out this way before Duncan and Tessa take him in after they catch him breaking into the antique shop.
- Training Montage: There are a number of these with Duncan teaching him how to wield a sword.

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.

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.

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, 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 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. 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 Compelling Voice, 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.
- Compelling Voice: Her biggest talent.
- The Medic: Shortly before her village was destroyed by the Horsemen and she learned about being Immortal, she showed an unusual skill for healing others.

- Voluntary Shapeshifting: Her encounter with a young Duncan implies she's capable of this, but never confirms it.

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.
- Back for the Dead: After returning from being Put on a Bus, (see the trope entry) he comes back for one episode to reveal that he and Mara were set up by Immortal Arms Dealer Andrew Cord, who intentionally sold them defective arms, then killed Mara when she confronted him in the aftermath of their group of revolutionaries being slaughtered.

- Dark and Troubled Past: 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.
- Deadpan Snarker: 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.
- Defeat Means Friendship: Charlie developed first a grudging respect and eventually a deep friendship with MacLeod after being unable to defeat Duncan in hand to hand combat.
- Elites Are More Glamorous: Spent 12 years in the military, during which time he became a Navy SEAL.
- Locked Out of the Loop: 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.
- Mixed Ancestry: Half African-American, half Italian.
- Overshadowed by Awesome: He's a former Navy SEAL, badass sensei and dojo master... who just so happens to be surrounded by Immortals, some of whom have centuries of practice in warfare, not to mention superhuman speed and strength.
- Put on a Bus: After falling for Mara, he leaves Seacouver to aid her with her revolution.
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.
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.
- Brainy Brunette: Doctors definitely have to be smart, and she can certainly rock the dark hair.
- Friendly Target: 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.
- I Just Want My Beloved to Be Happy: Duncan eventually came to this point of view about her.
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.
- Demonic Possession: 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.
- Evil Costume Switch: Swaps his brown fringed jacket for Kant's black leather.
- Evil Is Hammy: Before the Dark Quickening, Coltec is a low key, stoic man. After being overcome by the Dark Quickening, he really ups the ham and loses all restraint.
- Good Is Not Soft: 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.
- Hero of Another Story: He seems to have wandered for a while, helping others and killing evil Immortals as he encountered them.
- Magical Native American: A Native American who has literal magic powers and can draw evil and anger out of others.
- More Than Mind Control: He claims this, but it's never confirmed either way.
- Offscreen Moment of Awesome: 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.
- O.O.C. Is Serious Business: Coltoc acting aggressive is a big sign that something is very badly wrong.
- Retired Badass: Unlike Darius, he still lives in the world, but hasn't taken a head in decades until he runs into Harry Kant.
- The Older Immortal: He's about twice as old as MacLeod.
- The Stoic: Doesn't get riled, even during Immortal duels.
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.
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.

- Sexy Mentor: To Mac.
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 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.
- Fiery Redhead: Subverted. He's an unassuming guy who rarely loses his cool.
- Non-Action Guy: He's never seen involved in or showing any inclination towards combat. He's all about learning, and especially learning about the human mind.

- The Older Immortal: There are only a handful of Immortals still around who date back as far as Marcus.
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.
- Ain't Too Proud to Beg: When Clay has him defeated, he asks for mercy, because he wants to continue a life of learning and growing.
- Living Is More Than Surviving: Voices this opinion.

- Master-Apprentice Chain: Mentions that he considered Ramirez one of his better students, Ramirez went on to teach Connor, who taught Duncan, and so on.
- Master Swordsman: He had the reputation but lost any passion for fighting and combat, leaving him ripe to be defeated by a more determined opponent.
- Mentor Occupational Hazard: Like many of Duncan's past mentors/influences, he winds up dead in the same episode where he's introduced.
- Wrote the Book: At one point during their sparring, Ashe chides Duncan for using a technique in an inappropriate situation, and it turns out the move in question was one Ashe originally devised.
- Not-So-Harmless Villain: Benny's not a villain per se, but he's able to take MacLeod by surprise on the boat simply because he's the last guy you'd expect to get violent.
- The Friend Nobody Likes: Duncan seems to be one of the few people who can stand to be around Benny, and his feelings for him seem never get much higher than "amusedly tolerant".
A Iceni female immortal born in ancient Briton. She first died fighting the Romans during Boudica's revolt. She was eventually mentored by Roman General Marcus Constantine. She in turn mentored fellow contemporary Brit Alex Raven and centuries later Matthew McCormick. Duncan MacLeod encountered her during the 18th century. During the present story line she and her mortal husband were mugged and gunned down. She goes looking for revenge but MacLeod talks her out of it. In return she convinces MacLeod to tell Anne Lindsey about his own immortality and let her make her own decision about rekindling their relationship.
- Action Girl: Died fighting during Boudica's revolt (presumably the Battle of Watling Street).
- Crusading Widow: wants to take revenge against the gang that killed her husband. She kills one of the perpetrators but is talked out killing the rest by MacLeod.
- Due to the Dead: Seen giving funeral rites to a fallen comrade and his pregnant wife shortly after her first death.
- Tribal Face Paint: Wore this back during 60 A.D. as a matter of course (being a Celtic warrior and all). The clan markings go back on in 1995 once she begins her quest for vengeance.
Hamza el Kahir
- "It is all written."
- Always Someone Better: Hamza's not a bad fighter, but he's very aware of how much better Xavier is.
- Heroic Sacrifice: Willingly accepts a challenge that he knows will result in his death rather than allow Duncan to be killed.
- Mentor Occupational Hazard: A mentor of Duncan's killed by Xavier St. Cloud.
- Religious Bruiser: An impressive swordsman and an early convert to the Muslim faith.
- Screw This, I'm Outta Here!: His first reaction to being challenged by Xavier is to get out of town as fast as possible, hoping to lose him in the desert.
- Spot of Tea: Vastly preferable to alcohol.
- The Teetotaler: Due to his religion. He laughingly dismisses ale as a "vile concoction".
- Unknown Rival: He certainly knows who Xavier is, but it's ambiguous if Hamza knew he was actively being hunted.
- Vitriolic Best Buds: He's mentoring Duncan and the two genuinely care for each other, but each spends a lot of time bemusedly wondering how anyone could possibly enjoy/endure the food, climate, and customs of the other's country. The spinoff novel Highlander: Scimitar contains even more of this.
Minor Recurring Characters
Sgt. Thomas Powell
A Seacouver police detective who runs into Duncan several times early on in the series.
- Chuck Cunningham Syndrome: Is a recurring presence in all but one of the first four episodes of the show and becomes somewhat familiar with Duncan and Richie in that time. Despite this, he pretty much disappears without a mention as to why.
- Reasonable Authority Figure: In "Innocent Man", he's pretty quick to realize that Leo Atkins didn't kill Lucas Desiree and does his best to stop the sheriff Howard Crowley from persecuting him.
Another member of the Seacover police force who encounters Duncan and friends on occasion.
- Deadpan Snarker: Shows just a shade of this after the hostage crisis is averted, as he leaves the scene exhausted.SWAT Team Leader: What do you think happened out there?Kominski: I'm saving it for my memoirs.
- Retcon: His first conversation with Duncan in "Free Fall" indicates that he's the Commissioner. However, "Bad Day in Building A" places him as a Lieutenant.
- What the Hell, Hero?: Calls out the SWAT team leader in "Bad Day in Building A" several times for operating in a gung-ho manner that regularly risks the lives of the hostages.
Det. Ray Bennett
Randi Mac Farland
A Seacouver reporter who repeatedly ran into MacLeod and noticed that he was a Weirdness Magnet, she became convinced that he was some sort of Secret Agent for the government and attempted to get the true story for quite some time.
- Hot Scoop: An attractive reporter pushing at what she thinks is a big story.
Inspector Raymond Le Brun
A French detective who has a somewhat antagonistic relationship with MacLeod, as the two have crossed paths a few times.
- French Jerk: Completely averted. Maurice is one of the nicest characters in the series.
- Hidden Depths: He's mostly played for goofy comic relief, but Maurice is a genuinely well-meaning guy with a history of alcoholism and family problems.
- Supreme Chef: The man likes his food, and knows how to prepare it properly.
- The Friend Nobody Likes: At worst, Maurice was slightly annoying when Mac Leod initially met him. He quickly won over Duncan with his unfailing politeness and willingness to help in any situation.
Major & Recurring Villains
Xavier St. Cloud
- "I'm just trying to earn a few francs. After all, a man's got to live."
- Badass Decay: [In-Universe] 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.
- Big Bad Duumvirate: With Horton for two episodes.
- Combat Pragmatist: One of the biggest in the series. Perfectly happy to use poison gas or mortal gunmen to incapacitate other Immortals.
- Faux Affably Evil: Extremely polite and rarely raises his voice. He's also a nasty piece of work, and is seen using chemical weapons to commit robberies.
- Gentleman Thief: 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.
- Handicapped Badass: 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.
- Man of Wealth and Taste: 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.
- Mentor Occupational Hazard: 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.
- Not Worth Killing: He regards Duncan as this when they first meet and Xavier challenges Duncan's then-teacher. When Duncan attempts to answer the challenge in his teacher's stead, Xavier is shown to be completely willing to kill him, and is only stopped from doing so when his original target reappears.
- 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.
- The Dreaded: When he challenges Hamza el Kahir. It's made plain that Hamza knows exactly who St. Cloud is, and views accepting his challenge to be the same as committing suicide.
- Villain Forgot to Level Grind: In past centuries he was considered one of the most dangerous Immortals in the world, but he's not anymore.
- You Have Outlived Your Usefulness: 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.
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.
- Big Bad: In Season 2.
- Crazy-Prepared: During his second encounter with MacLeod we see he has an escape boat prepared and wears a bulletproof vest.
- Fantastic Racism: 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. Word of God says he became this way after being The Kurgan's watcher and forced to document his atrocities.
- Final Solution: Thinks that he needs to kill all Immortals in order to prevent them from ruling or killing mortals.
- Knight Templar: Wants to save humanity by eliminating all Immortals.
- Manipulative Bastard: 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.
- Moral Myopia: When he and his Watchers kill people for absolutely no good reason, it's okay, but when Immortals do it...
- Not Quite Dead: Several times.
- Offscreen Villainy: He and his men killed an unknown number of Immortals prior to taking on MacLeod.
- Outside-Context Problem: Serves as this for the Galatis and Hugh Fitzcairn, among others. Presumably none of them ever dreamed there was a paramilitary organization collecting information about them and observing their every move, with the sole goal of exterminating all Immortals.
- Screw This, I'm Outta Here!: He retreats the moment he learns that MacLeod has tracked Xavier and himself to the stables.
- The Watcher: The renegade one.
- Villain of Another Story: Jacob and Irena Galati's, for a start.
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.
- Beard of Evil: Kalas is about as nasty as Immortals get, and he always has some form of facial hair.
- Been There, Shaped History: Implied in the '20s when he mentions that fellow opera star Enrico Caruso is dying in New York. "People say he was poisoned."
- Big Bad: Of the third season. He spends all of Season 3 hunting down Duncan and Duncan's friends, attempting to ruin their lives or kill them, (succeeding in a few cases) and it's not until the season's final episode that he and Duncan settle things.
- Devil in Plain Sight: Duncan was the only one to suspect Kalas' true nature during his stay at the monastery.
- Disproportionate Retribution: MacLeod got him kicked out of a monastery by exposing Kalas' heinous deeds. As a result Kalas vowed revenge on Duncan and anyone MacLeod is close to. (Duncan accidentally ruining Kalas' singing voice by slashing his throat during a past fight didn't mitigate Kalas' desire for revenge either, but Kalas has nobody but his own vengeance crazed self to blame for that one.)
- Engineered Public Confession: 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 Kalas said that...
- Evil All Along: 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.
- Evil Sounds Raspy: MacLeod cut him with a piece of glass during a past duel, ruining his beautiful tenor voice.
- Guttural Growler: Had his throat slashed by Mac in the '20s. He survived; his singing career did not.
- It's All About Me: Seems to value his singing voice much more highly than the lives of other people.
- Manipulative Bastard: 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 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.
- Revenge by Proxy: He would kill or frame anyone who is somehow related to MacLeod, and he does kill several Immortals who are friendly with MacLeod, including Hugh Fitzcairn.
- Sadistic Choice: Tells MacLeod during the last episode of season three that if he doesn't 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.
- 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.
- Wicked Cultured: 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.
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.
- Combat Pragmatist: Out of necessity. His targets are unsuspecting, and he attacks from behind.
- Creepy Child: He looks 8, but he's really closer to 800. As a result he has some completely unchildlike motivation hiding below the surface.
- Karma Houdini: 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.
- Wounded Gazelle Gambit: 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.
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 Wild West as the leader 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.
- Bash Brothers: Used to be this thousands of years ago with his fellow Horsemen, and briefly was again in the modern day.
- Beard of Evil: Back in The Wild West.
- Been There, Shaped History: The Horsemen's exploits influenced The Bible. He also mentions being in England when the Bubonic Plague hit, with the possibility that he may have played a part in that.
- Blood Brothers: Implied to have this relationship with Methos and the other Horsemen.
- Blood Knight: Seems to have an excessive love for combat, death and destruction, fittingly for someone who's the historical basis for one of the Four Horsemen of the Apocalypse.
- Combat Pragmatist: The pommel and handguard of his sword are decorated with short spikes for additional damage during close combat.
- Good Scars, Evil Scars: Has an impressive one on the right side of his face.
- Hellbent For Leather: Favors a leather jacket in the modern day. The production crew gifted it to actor Valentine Pelka after shooting.
- Horsemen of the Apocalypse: Was the leader of the group that inspired the Horsemen of the Bible.
- Manipulative Bastard: Skillfully manipulates Methos of all people, at least for a while, though reminding Methos how much he sometimes still missed being Death didn't work the way he wanted it to.
- The Older Immortal: 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.
- The Sociopath: 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 losing a battle to Macleod): "I am the end of time!"
- Tom the Dark Lord: Known back in the Wild West days as Melvin Koren. His Watcher file shows that his known aliases over the years include Eugene Korinski and Dexter Korvin, with speculation that Kronos deliberately chooses nerdy-sounding names to increase the possibility of a bar fight.
A member of the Four Horsemen, and a deranged psychopath who admired Kronos but didn't get along very well with the other members.
- Bash Brothers: Downplayed, as he seems to be the troublemaker of the Horsemen, but he's still this with the group.
- Beard of Evil: If you had any doubt that Caspian is unhinged and evil, just look at his facial hair.
- Combat Pragmatist: 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.
- Dual Wielding: Gleefully attacks MacLeod with a sword and knife.
- I'm a Humanitarian: "They found parts in his basement, in his garden, in his freezer." It's indicated in a deleted scene that he believes consuming the brains of others will make him smarter.
- Serial Killer: "Nobody knows how many people he killed."
- Tattooed Crook: Tattooed asylum inmate
- Wild Hair: How he seems to prefer keeping his hair, as he declines to cut it even after being let out of the asylum.
A member of the Four Horsemen, he's a ruthless warrior in combat but almost childlike outside of it.
- Ambiguous Disorder: Seems somewhat mentally challenged.
- An Axe to Grind: And it's a huge one straight out of an over the top fantasy novel.
- Bash Brothers: With the other Horsemen, particularly Methos.
- Blood Knight: 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.
- Combat Pragmatist: As he says to Duncan when both Silas and Caspian confront Duncan: "You kill one of us, the other takes your head while you're down."
- Dumb Is Good: Well, he's both the dumbest and least evil of the Horsemen. Although that's Damning With Faint Praise.
- Dumb Muscle: It's likely that he is somewhat mentally challenged, but he makes up for it with his strength and battlefield skills.
- Evil Sounds Deep: Was one fo the Four Horseman and has quite the deep, booming voice.
- Psychopathic Manchild: 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.
- Retired Monster: He seems to have given up marauding by present day, but jumps at the chance once Kronos starts getting the band back together.
- Stout Strength: He's no bodybuilder, but he swing around that huge axe of his quite easily.
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. He mainly appears in the form of Duncan's old foe James Horton.
- Expy: His statue shares many similarities to that of Pazuzu of The Exorcist films, another famous demon. Their mannerisms and methods are quite different however.
- Hero Killer: By proxy. He used illusions that seemed real to cause MacLeod to accidentally kill Richie.
- Master of Illusion: And he manipulates illusion to defeat and torment his targets. Or get them to kill their friends.
- Outside-Context Problem: Even the most vile and depraved Immortals are still human beings. Who was prepared for an intangible, shape shifting demon?
- Prop Recycling: Ahriman takes the form of villains Kronos and James Horton, old foes of Duncan. Kronos is even dressed in his Bronze-age warrior costume, an outfit that Duncan never saw him in.
- The Power of Hate: Ahriman feeds off the anger of his victims and gets weaker the more calm and serene his opponent gets.
Single episode villains
- Badass Longcoat: The first of many.
- BFS: Not to anime proportions, but still one of the biggest seen in the series. Word of God is that he designed and built it himself.
- Beard of Evil
- Combat Pragmatist: When it appears that Connor is outmatching him in their duel, Slan proceeds to unleash a sneak attack by firing a dagger from the hilt of his sword into Connor's heart.
- Cool Car: It's only seen briefly, but Slan seemingly shares Duncan's affection for older cars.
- Evil Sounds Deep: A violent psycho with a deep voice.
- Fingerless Gloves: Wears them while swords fighting.
- Large Ham: His actor was definitely having fun being a sneering villain.
- Rage Helm: Wears a nasty-looking mask during duels.
- Super Window Jump: The first villain of the series enters through a skylight.
- Unknown Rival: Slan is one to Duncan and has one himself in Conner.
- Combat Pragmatist: If you can have a small army of mortal warriors who are immune to pain and will obey your every command, why risk yourself?
- Determinator: Spent three centuries in a temple refining his drug.
- I Am Not Left-Handed: He and MacLeod do this back-to-back, with Kiem Sun revealing that he's nowhere near as rusty or out of shape as would be expected after hundreds of years out of the Game.
- Karma Houdini: Duncan punishes him by pouring out the remainder of the potion that Kiem Sun had spent so long perfecting, before telling him that it will be a duel to the death if they ever meet again. Kiem Sun is never seen again after this, but given how his residence is on holy ground, it's hard to say whether or not he would be able to receive proper comeuppance.
- Knight Templar: Claims that his original goal for the potion was to help mankind. Eventually, though, it proceeded to the point that he wanted to use the potion to brainwash people into helping him fight other immortals.
- The Only One Allowed to Defeat You: Invoked, somewhat. After Duncan defeats Chu Lin and expresses a desire to send him to prison, Kiem Sun charges in and strikes Chu Lin down.Kiem Sun: Forgive the intrusion, but he was mine!
- So Proud of You: Kiem Sun appears to have this look when he is allowed to observe Duncan and Kiem Sun dueling, but the revelation of his betrayal a few moments later implies that it was (at least partly) an act on his part. Regardless, he does compliment MacLeod for his skill during their subsequent duel.
- Villainous Breakdown: After Duncan beats him physically and verbally, he slowly folds up, looking genuinely frightened and uncertain.
- Warrior Monk: He's a Buddhist monk in present day.
Felicia Martins/Felice Martin
- Evil Sounds Raspy: A villain played by Joan Jett, so it's a given.
- Femme Fatale: Plays off of Richie to the point of fully seducing him. She ends up using him to draw Duncan out to their confrontation at the end of the episode.
- Forgery: She's extremely good at it, too. A map of London that she created two hundred years ago fools Duncan perfectly. The expert he takes it to for authentication notes that it may not be an original Corinelli, but given its age and obvious quality, "it's as damn near as makes no difference."
- Karma Houdini: Duncan bests her in combat, but chooses not to kill her, instead warning Felicia not to approach his friends again. This is the last we see of her.
- Obfuscating Stupidity: Is introduced as an apparent latent immortal who discovers her power after making a suicide attempt. However, it turns out that she's actually been engaging in the game for at least 200 years (while pulling off a successful run of selling forgeries to boot).
- Sex Slave: Was used as one by her original mentor Pierrer Bedard until he got bored with Felicia and tried to kill her. She ended up taking him out instead.
- The Svengali: Her mentor is stated as having been one.
- Woman Scorned: Did not take Claude Devereux leaving her to start a family with a mortal lover well. She eventually tracked down his home and killed his lover and adopted daughter while he was out of the country. Even though he spends the next century tracking her down for revenge, she ends up besting him when they finally meet again.
- An Axe to Grind: He wields a realistically sized axe as his weaponOfChoice.
- Even Evil Has Loved Ones: Genuinely cares for his adopted son Joshua.
- Evil Sounds Raspy: Probably has the raspiest voice in the show with the possible exception of Kalas, and he is a bad, bad man.
- Mountain Man: Has spent centuries living in the mountains and the wild.
- Nice Hat: Caleb makes his first appearance wearing one. He takes it off when speaking to Tessa and it's never seen again.
- Perma-Stubble: Looking like you haven't shaved for a few weeks is part of the whole Mountain Man thing.
- Screw This, I'm Outta Here!: Once he knows there's another Immortal around, he gives the order to get off the mountain as quickly as possible, with no more stops.
- MacLeod: "I never fed off human blood and misery to gain power."Voshin: "And pleasure. Don't forget pleasure."
- Beard of Evil: Has the stereotypical 80s corporate executive beard.
- Corrupt Corporate Executive: During the 80s. Apparently part of the reason he faked his death was to become a Karma Houdini with money that he stole from the company.
- The Sociopath: Perfectly willing to intentionally use a devoted lover as a pawn with the intention of using her death to help him.
- Beard of Evil: A goatee
- Burn the Witch!: Was the victim of this in the past after revealing his Immortality.
- Famous Last Words: "Lenora . . ."
- Knife Nut: Part of his MO as a serial killer. He's introduced threatening a woman with an extremely large knife, which he then uses to stab Duncan.
- Master Actor: We never see him perform, but seems to have this reputation In-Universe.
- Monster Sob Story: Three hundred years ago, Korolus revealed his immortality to his lover, Lenora, who had him burned at the stake. The betrayal (and perhaps the pain of being burned alive) caused a break with reality. He's since become a serial killer, fixating on slender blonde women and believing that they are the long-dead Lenora.
- Serial Killer: Kills multiple women who remind him of the lover who betrayed him.
- Sharp Dressed Man: Dressed in tails, vest, and spats.
- Dirty Cop: He murders an ex-lover, and is implied to have done this on other occasions in the past. He tries several times to kill Tessa and is apparently willing to murder other cops in the process. He's also able to use his position in law enforcement to "discover" the bodies of Immortals that he kills and divert attention from himself.
- Unknown Rival: When Duncan discovers Ballin in his home, he has no idea who he is, and, before their final duel, Ballin states that he hadn't intended to come for Duncan "yet".
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.
- Arms Dealer: His main occupation in the show's present.
- Been There, Shaped History: 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.
- Brief Accent Imitation: Momentarily affects a broad Scots accent while talking to Mac.
- Cool Sword: A Kris broadsword.
- The Dreaded: The first Immortal that actually frightens Duncan. Several seasons later, we find that the Watchers regard MacLeod's victory as a huge (albeit pleasant) surprise.
- Good Smoking, Evil Smoking: "I know. These things will kill me."
- The Older Immortal: When speaking to Richie, Duncan explicitly refers to him as "one of the few ancient immortals left".
- Revenge by Proxy: Strikes at Darius by killing Darius' students and the people inspired by Darius.
- War for Fun and Profit: Part and parcel of being an arms dealer.
- We Can Rule Together: Tells Duncan they should work together. "Not long, a century or two. We could really do so much."
- Worthy Opponent: "Worthy" may be an overstatement, but he does hold Duncan in a certain regard and seems to respect his fighting abilities.
- Years Too Early: 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.
An assassin who managed to successfully kill a French noble Duncan was guarding in the late 18th century, he continues to ply his trade in modern day France with a whole group of mortal assistants.
- Affably Evil: He's quite pleasant... even up until he kills you.
- Badass Boast: "I don't want you to think I'm bragging, but I'm the greatest assassin in all of history. Of course, there have been men responsible for more deaths, but, ah, none of them killed so many, so close."
- Combat Pragmatist: 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.
- Enemy Mime: Throughout history he has had a preference for performing as an entertainer, and using that as a way to get close to his targets. In 90s Paris, he and his mortal henchmen tend to dress and act as mimes.
- Evil Has a Bad Sense of Humor: 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."
- Harmless Villain: He's a prolific assassin, but the only time he's a threat to MacLeod is during a sneak attack while Duncan is unarmed. When he shows up again, years later, Mac is completely unconcerned.
- Hellbent For Leather: A studded overcoat that he usually pairs with a white scarf.
- Master of None: Claims to be this with regards to everything aside from killing. He claims to have some small skill and natural talents in a variety of fields, (acrobatics, singing, etc.) but the only thing he was truly good at was being an assassin.
- Professional Killer: Has spent centuries as a highly effective assassin, and has personally killed 2,760 people.
- Small Role, Big Impact: A flashback reveals that it was his surprise attack on MacLeod that led to Duncan and Tessa meeting.
- Trademark Favorite Food: The man loves his absinthe.
- Would Hurt a Child: To keep MacLeod in line, he threatens to have one of his men unload an automatic into into a nearby crowd, half of whom are kids.
- Escape Artist: He kills a guard, slips out of his straitjacket, and escapes from a moving police van, all in about sixty seconds. He later acknowledges the necessity of getting outside of the walls first, since escaping from a maximum security prison was beyond even his abilities.
- Improvised Weapon: Uses a trashcan lid as a shield during his fight with MacLeod.
- Shield Bash: He also smacks Duncan pretty soundly with it.
- Insanity Defense: Claims to have used a version of this to get himself outside of the prison where he was being held, making an escape much easier.
- Revenge: As soon as he's free, he goes right for Amanda.
- Berserk Button: Don't even imply that he's lying about his military record.
- The Casanova: He has three prolific centuries of experience with the ladies.
- Fashion Designer: He's been creating clothes for women since the 1800s.
- Gentleman Thief: He seeks out jewelry and art associated with the most beautiful women of history.
- It's All About Me:I, too, have principles. And the first among them is that I never give up that which I have acquired.
- Karmic Thief: When Duncan catches him stealing a necklace he'd promised not to, Piton counters that the dutchess in question is incredibly rich and will never miss it.
- Man on Fire: Courtesy of Richie.
- Sharp Dressed Man: Always well dressed, even before he dove into fashion design.
Col. Everett Bellian
- Determinator: Put any obstacle in his path that you want to keep him from his goals. See if it does any good.
- Even Evil Has Loved Ones: He loved Lori's mother deeply and cares very much for his stepdaughter.
- Evil Virtues: For a given value of evil. Honor. He gets the drop on Duncan in the fog, and comments that he could easily shoot him and take his head. Duncan simply replies that he won't, and Bellian immediately puts the gun down and draws his sword for a fair fight.
- Nothing Personal: He's got nothing against MacLeod and doesn't have any interest in fighting him or taking his head. When they finally draw down on each other, it's clear that Bellian regards their duel as merely a means to an end.
- Revenge Before Reason: Bellian is furious about the rape of his stepdaughter, and has no patience with a legal process that he's convinced will allow the rich and well-connected attacker to get off easily.
- Villain Has a Point: Bellian's methods are terrible, but his concern that Mark would use his father's money and diplomatic immunity to escape punishment is actually reasonable, particularly since it's implied throughout the episode that Mark has done so before, albeit for less serious offenses.
- Worthy Opponent: He considers Duncan to be one.
Quentin Barnes/Michael Moore
- Buried Alive: Barnes was executed in the electric chair and buried. It was thirty-three years before he got free.
- Dying as Yourself: Subverted. Moore does his best, and takes control long enough to urge Duncan to do what's necessary, but the Barnes personality is clearly on display when Mac takes his swing.
- Evil Sounds Deep: Barnes is a killer who has a voice that is very deep.
- Evil Sounds Raspy: In addition to being deep, it sounds like it's being dragged over a stone floor.
- Split Personality: Moore has developed one, and acts as both himself, (kind, thoughtful man) and Quentin Barnes, (sadistic, unhinged criminal) the man Moore believes killed his wife.
An Immortal and acquaintance of Duncan's who became a fanatical member of a pro-Irish Independence movement after her mortal husband was killed by the English. She continues to fight for the cause into the show's present, when her group planned to assassinate a British ambassador on vacation in America. 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. MacLeod chastises her afterward for her overdeveloped sense of vengeance and convinces her to return to Ireland rather than continue the grudge.
- Avenging the Villain: Her mortal husband died when Richie interfered with their attack, and now she wants revenge,
- Fiery Redhead: She has a temper and "an overdeveloped sense of vengeance", and has the flaming red hair to go with it.
- Starter Villain: The first Immortal Richie faces in combat.
- Your Terrorists Are Our Freedom Fighters: An IRA member that Duncan has worked with and been friendly with in the past.
- Combat Pragmatist: He's introduced attacking MacLeod from behind. Later, he maneuvers the fight into a carnival funhouse for cover, and again strikes from behind.
- You remember, MacLeod, all that separates us from the beasts is the law.
- Beard of Evil: Closely cropped and graying, regardless of the era.
- Bounty Hunter: Operated as a sheriff in the past, today he's a legal bounty hunter.
- Cool Car: Averted, unlike Duncan, his truck seems to be mostly utilitarian.
- Combat Pragmatist: He leads Richie through some building renovations and throws debris at him, strikes from hiding, and in general tries to make use of the terrain. It ends poorly for him.
- Defiant to the End: He's pretty well screwed once he falls through the tabletop, but he keeps swinging til the very end.
- Determinator: He will never stop hunting a target until they are caught or killed.
- Good Scars, Evil Scars: A dandy one along the right side of his face.
- I Am the Noun: "I am the law."
- Principles Zealot: He has a very Hobbesian view of the world, and thus sees people as little more than animals who need laws to be kept in line. As a result he takes the law and any violations of it incredibly seriously, and with little to no room for mercy.
- Quick Draw: Mako's shown to be fast with a gun in 1882. He and Duncan have a brief, Western-style stand-off in the dojo, and he loses handily.
- Famous Last Words: "Everyone's a critic".
- Hellbent For Leather: In present day.
- Man in White: In his final scene, he's wearing a white three piece suit and an off-white overcoat.
- Sword Cane: In 1840. By 1993 he has switched to a small broadsword.
- The Older Immortal: "How many years have you been doing this?" "For longer than you've been alive."
- Balding Of Evil
- I Am the Noun: "I am history."
- Nice Hat: We see him in both a fedora and ushanka.
- Soft-Spoken Sadist: Does not like to raise his voice.
- The Man Behind the Man: His preferred method of operation. Being Immortal precludes him from being a public figure, so he settles for running things behind the scenes.
- Wicked Cultured: In the present, he and MacLeod meet by chance at a ballet performance.
- Buried Alive: For almost two thousand years. Fortunately, she seems to have been unconscious for it.
- Translation Convention: As she's been unconscious in a sealed stone box for thousands of years, there's no way she could possibly know English. Fan theory holds that she, Duncan, and Constantine are speaking either Latin or Hellenic Greek between themselves.
- Wakeup Makeup: Wakes up after thousands of years in a sarcophagus... and of course, looks stunning. And speaks English.
A former pupil of Rebecca Horne, Amanda's first teacher. He's become obsessed with the legend of The Methuselah Stone, which is said to magnify the power of any Immortal who possesses it, among other things. Believing it to be the key to winning the Game, he has hunted down all of Rebecca's students who were given a piece of it, except for Amanda herself, in his quest to collect all the pieces.
- Bald of Evil: Has a shaved head and is completely ruthless.
- Beard of Evil: As a natural compliment to his toughness and shaved head.
- Determinator: Luther wants the Methuselah Stone fragments, and nothing short of death will stop him.
- I Gave My Word: He agrees to let Rebecca's mortal husband live if she lays down her sword, claiming that he always keeps his promises.
- The Unfettered: Has no problem with killing off his former mentor and all her other students if it means he will be invincible.
A head hunter committed to winning The Game, his specialty is terrifying new Immortals and hounding them until they flee to their teachers for help and refuge, only for Hyde to promptly challenge those teachers and take their head. He disdains taking the head of anyone who isn't already a powerful and capable fighter.
- Ax-Crazy: Hyde takes great pleasure in killing, whether as part of The Game or just for pleasure, and is deeply unhinged.
- Badass Longhair: The first few times he encounters Duncan; it's much shorter in present day.
- The Dreaded: Is a feared headhunter, and one of the more terrifying Immortals encountered.
- Egomaniac Hunter: He frequently talks about the pleasure of a good hunt, and makes it clear that winning the Game is secondary to the pleasure of a challenging kill.
- Mentor Occupational Hazard: Hyde IS the hazard; frightening younger Immortals into leading him to their teachers and then killing the teacher has been his method for centuries. The first time he meets Duncan, it's his (unsuccessful) attempt at tracking down Conner MacLeod. During their second meeting, he kills Pierre Segour, Duncan's then-mentor.
- Not Worth Killing: "You're not worth the time . . . I've hunted and killed worse than you for exercise." He's more than capable of killing both Duncan and Ritchie during their initial meetings, but Hyde's after bigger game. He literally has his sword to MacLeod's throat at one point and lets him go.
- Paranoia Fuel: He invokes this, as his specialty is murdering everyone around young Immortals while remaining unseen.
- Perma-Stubble: No matter what era he's in, he sports some thick stubble.
- Unknown Rival: He and Duncan first meet while Hyde is hunting Conner, and the elder MacLeod is almost certainly unaware that he's being pursued. Hyde is unable to locate him and eventually abandons the search; Duncan never says whether he subsequently mentioned the encounter to Conner or not.
- Dual Wielding: Saber and Bowie knife.
- It's Personal: Killed a mortal wife of Duncan's, so for Duncan it's very personal with Kern.
- Motorcycle Jousting: He rides down on MacLeod, who is on foot, and takes a swing at him in passing. Duncan blocks the attack, and Kern dismounts to continue the fight.
- Perma-Stubble: In keeping with Kern as an uncivilized, animalistic villain.
- Politically Incorrect Villain: Openly mocks the Native Americans he slaughters and Duncan for having lived with them and taken on their ways.
- Rape, Pillage, and Burn: His M.O., especially towards Native Americans in the American West.
John Durgan/Armand Thorne
- Beard of Evil: A goatee.
- Greed: One of the driving forces in Thorne's life, almost to the point of Blue and Orange Morality. He loves learning, with a particular interest in languages and art, but his real passion is acquiring and possessing things. He values his art collection above human lives, and has a brief Freak-Out when Joe threatens to knock a few items off a table. Thorne has done his best to remove himself from The Game, and tells MacLeod that the only time he'll pay it any mind is if he's one of the last two remaining.
- Lack of Empathy: Completely indifferent to the lives of others.
- Omniglot: Claims to speak nine languages, including Latin and Greek.
- Rags to Riches/Self-Made Man: An extremely evil version involving murder and theft, but he transformed himself from an illiterate trapper into a wealthy, articulate, and powerful man.
- That Man Is Dead: As far as he's concerned, John Durgan hasn't existed for years.
- The Scrooge: "I sell nothing, and nothing is ever taken from me."
- "You know what they say about love and war."
- Combat Pragmatist: Has inexperienced female Immortals seduce his targets, then takes their heads while they're distracted.
- Evil Mentor: Recruits young female Immortals to use them for his own pleasure and to distract his foes, with no care about whether it gets them killed.
- Manipulative Bastard/Opportunistic Bastard: Axel's ready for a fight, but he changes tactics immediately upon realizing that Michelle is truly new to The Game.
- Sexy Mentor: Pretends to be one.
- Skunk Stripe: Very prominently displayed in present day.
- You Have Outlived Your Usefulness: How he views his proteges if he can't make use of them anymore.
A former friend of MacLeod's, he was a famous swordsman who came to dread always being challenged by mortals and Immortals alike who wanted to take his title of best swordsman in Europe. Leaving Europe to live in America didn't really change things, and eventually his only refuge was a hardcore opium addiction.
- Addled Addict: Has sunken deep in addiction and it has done terrible things to his mind and life.
- Cool Car: Much like Duncan, he favors a classic muscle car.
- Evil Counterpart: With his classic convertible, long hair, and formidable swordsmanship, he comes across as a paranoid, self-destructive version of MacLeod.
- Fallen Hero: Was once a friend of Duncan's and an admirable man. Now he's a paranoid addict with no concern for others.
- Master Swordsman: The best in Europe during the early 1800s.
- The Perils of Being the Best: In one of the classic versions of this trope, he was continually challenged throughout multiple lifetimes by people looking to take his title as the greatest swordsman, until it sent him into addiction, paranoia, and destroyed him.
- Clothing Combat: Uses his cloak as a distraction in his first fight with Duncan and strangles a man with his scarf in present day.
- Nice Hat: A cool top hat, which he tosses to Matlin for safekeeping before he and MacLeod duel.
- Not Worth Killing: His first duel with Duncan has shades of this. Kurlow, who is clearly unconcerned throughout the fight, leads Duncan into a hedge maze and simply walks away while a lost Duncan tries to navigate the maze and find Kurlow again.
- Skunk Stripe: Specifically mentioned in dialogue as an identifying feature.
- Those Two Guys: With Matlin. The two were longtime friends and criminal partners.
- Villainous Friendship: Was genuinely close to Peter Matlin.
- Bald of Evil: Very bald, very bad.
- Posthumous Character: We only see him from behind for a few seconds in present day before Duncan kills him.
- Those Two Guys: With Kurlow. The two were longtime friends and partners in crime.
- Villainous Friendship: He and Kurlow were genuinely close and valued each other.
- Combat Pragmatist: Pragmatic in that he tends to attack other Immortals when they're unarmed. The Watchers all agree that he wouldn't have lasted a minute against someone like May-Ling Shen if the encounter had been remotely fair.
- Man in White: White pants, shirt, and boots topped with a gray overcoat.
- Actual Pacifist: By his own account, he doesn't fight any more, and stopped carrying a sword altogether sometime between 1975 and 1995.
- The Atoner: Looking to make up for his past and all the destruction he caused.
- Despair Event HorizonIn my life I've seen much horror. Much destruction. With every war it grew harder and harder to see. But with this one, this time . . .
- Even Evil Has Standards: An interesting case. Kage has no problem threatening the lives of children or putting them in harm's way, as he does in Cambodia. Yet when he returns to the area to challenge Duncan, he sees the graves of the children he threatened and drops to his knees in tears.
- Face Death with Dignity: He understands Duncan's judgement of him, and doesn't resist or try to run when it appears that Duncan will kill him.
- Heel–Face Turn: Kage is an evil man, but even he recoils at the actions of the Khmer Rouge.
- Retired Monster: Seeing the atrocities of war one time too many broke through his hardened exterior and made him retire the monster inside himself.
- Badass Moustache: An impressive one in 1755. He's cleanshaven today.
- And I Must Scream: Spent several decades at the bottom of the Seine.
- Those Wacky Nazis: Lived his life as a Nazi before discovering that he was Immortal.
- Never My Fault: Always finds a way to blame his actions on others, whether there's any real justification for it or not.
- Evil Mentor: Found a young Lucas Kagan and raised him to be the perfect partner in crime, eventually shooting him to trigger his immortality.
- Mentor Occupational Hazard: Was a mentor to a young Kagan. Duncan killed Tarsis but gave Kagan a chance at life, sparing him because of Kagan's youth and the bad example set by Tarsis.
- Sharp Dressed Man: Never not wearing a vest, and almost always with a suit and tie.
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.
- An Axe to Grind: He claims to have wielded the same axe for centuries, and after losing it, spent centuries more looking for it.
- Barbarian Longhair: It's shoulder length when he and Duncan first meet. He wears it shorter and slicked back today.
- Dead Person Impersonation: In the present he pretends to be a priest that he killed.
- Determinator: He's been searching for the axe that MacLeod took from him for three hundred years.
- The Dreaded: The locals from MacLeod lands still fear him and his "ghost" that seems to be at work.
- Dual Wielding: Sword and axe, very briefly.
- Exact Words: In his disguise as Father Laird, he likes to use these to hide his intentions. He also has a fondness for wordplay in general, such as telling a grave robber that he hired that betraying him "would be a grave mistake".
- Face Death with Dignity: Attempted to do this when Duncan first defeated him. Realizing he was mortally wounded and helpless to stop Duncan from taking his head, he simply attempted to hold onto his axe and told Duncan to strike and send him to Valhalla.
- Historical In-Joke: Both the name of his ax and his mentor (which are only mentioned in bonus materials) seem to be references to Ragnar Lodbrok and His Sons.
- Horny Vikings: He was originally a Viking.
- Maybe Magic, Maybe Mundane: He points out that, whether MacLeod believes in the magic Kanwulf used or not, Kanwulf performed the ritual sacrifices and the one man who could get Kanwulf what he wanted showed up at his doorstep.
- Names to Run Away from Really Fast: Kanwulf the Destroyer.
- Near Villain Victory: In his first bout with Duncan, Kanwulf dominates Duncan and easily pushes the younger Immortal around, and is only defeated when Duncan just barely dodges a killing blow and manages to stab the overextended Kanwulf.
- Pragmatic Villainy: Once the axe is returned, Kanwulf seems perfectly willing to let MacLeod walk away without any revenge for having taken it in the first place and sending him on a three hundred year treasure hunt.
- Ring of Fire: Duncan sets one before their final fight.
- Starter Villain: He was the first Immortal that Duncan faced, and while a capable enough fighter, nonetheless Duncan managed to inflict a mortal wound on him. Unfortunately Duncan had not yet been taught about immortality, so Kanwulf would get a chance at a rematch centuries later. While he was a difficult challenge for a young Duncan, in the show's present Duncan is more than a match for him and dominates the fight with Kanwulf much as Kanwulf had dominated the fight with Duncan centuries earlier.
- Villain Respect: When Duncan comes to avenge Ian, Kanwulf recognizes the sword Duncan is carrying and says that Ian fought well when the two met in battle.
An Immortal African-American born in the 19th century, Cord fought in the American Civil War hoping to bring freedom and equality to his people, but was appalled by the result. 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.
- Arms Dealer: And in some cases, he will intentionally sell defective weapons to people.
- Combat Pragmatist: 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 Weapon of Choice rather than swords.
- Evil Counterpart: 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 Jumping Off the Slippery Slope or crossing the Moral Event Horizon) 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.)
- Evil Former Friend: To Joe Dawson. He saved Joe's life in Vietnam, but has since turned to acting selfishly and amorally.
- Fallen Hero: 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.
- Historical In-Joke: Supplemental materials claim his first Immortal teacher was Robert Gould Shaw, the Colonel in charge of 54th Massachusetts Regiment, a regiment made of black men fighting for the north in the American Civil War.
- I Lied: Promises not to kill Charlie for the sake of Joe... and then kills Charlie in a knife fight anyway.
- The Nicknamer: Joe is "boy scout".
- I Owe You My Life: Dawson feels this way toward Cord, as Cord went to extraordinary lengths to save Joe in Vietnam.
- Semper Fi: He's served in several different military branches, including the Marines in Vietnam.
- Then Let Me Be Evil: Cord's experiences with racism and persecution crushed the idealism and optimism he had when he was young, and led to him adopting a selfish, nihilistic philosophy of valuing only money and getting ahead.
- Canine Companion: Three Rottweilers.
- Combat Pragmatist: Uses his dogs to attack other Immortals, wearing them down for an easy kill.
- Even Evil Has Loved Ones: Kanis is a thoroughly nasty guy, but he genuinely loves his dogs. (Well, the males, at least. As the breeder points out, life isn't very great for his female dogs, who are simply used repeatedly as brood mothers.)
- Evil Sounds Raspy: Ranks with Kalas and Caleb Cole as one of the raspiest villains in the series.
- Flunky Boss: Attacks other Immortals while his dogs are distracting them.
- Hellbent For Leather: One of the biggest examples in the series.
- Meaningful Name: Kanis/canine.
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.
- A Fate Worse Than Death: 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.
- Cruel to Be Kind: Duncan argues hard to get the other sailors to maroon Kincaid instead of beheading him, thus sparing his life. Kincaid, who spends the next hundred years repeatedly dying of starvation, does not particularly appreciate the mercy.
- Greed: In his own words "I will not lose 100,000 pounds for the sake of a few lives".
- Moral Myopia: 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.
- The Neidermeyer: 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.
- Reduced to Ratburgers: 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.
Col. Simon Killian
- Colonel Kilgore: 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.
- A Fate Worse Than Death: Spent seventy years in a mental asylum thanks to Duncan
- Revenge: Plans to keep Duncan locked in a cell for the next seventy years.
- Sanity Slippage: 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.
- Spiders Are Scary: Killian keeps a lot of pet spiders, and attempts at least one murder with them.
- Villain Has a Point: During his court martial rant, the obviously unstable Killian correctly predicts that unless Germany suffers a crushing military defeat, another war between the Allies and Germany will be inevitable.
- Agent Peacock: Kinman is very much this in the 1700s. Snobby, effete and loudly dressed, he's still a deadly swordsman. His clothes and manner are much more reserved in the 90s, but some of his more flamboyant hand gestures still pop up here and there.
- Combat Pragmatist: Tries to shoot Duncan several times before he ever draws his sword.
- Professional Killer: We see him working as one in 1712 and the present.
- White Anglo-Saxon Protestant: One of the reasons the Queen forbids Duncan from avenging Keating's death; her court is already fractious, and a public duel between a Catholic Scotsman and a Protestant Englishman will only divide it further.
- Troll: He goads Keating into a duel by calling his integrity into question. Once the duel is concluded, a further barrage of insults pushes Keating to attack again, and Kinman kills him. He later goes back to the tavern where Duncan is staying to rub his nose in the loss, and brings it up again almost three hundred years later.
- Your Mom: The insult that finally provokes Dennis Keating into attacking him again.
- A God Am I: "I am India. I am Kali."
- Choke Holds: Strangles his targets with a silk cord.
- Last of His Kind: Last of the old style thuggees.
- Religious Bruiser: A fervent worshiper of the goddess Kali.
- Simple Staff: His weapon of choice. He easily bests Duncan in a sparring session, and Duncan's expression just before the sparring began indicates that Duncan expected exactly that outcome.
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.
- Bad Boss/I Will Punish Your Friend for Your Failure: 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.
- Evil Only Has to Win Once: 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 occurrence 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.
- Fairest of Them All: She was considered one of the most beautiful women in Europe during her youth, and is obsessed with holding onto her looks.
- Hollywood Personality Disorders: Neatly ticks many of the boxes associated with Narcissistic Personality Disorder, including being friendly and generous until perceiving someone as having betrayed her or coming between her and something that she wants.
- If I Can't Have You...: Has a tendency to kill either men who reject her, their lovers, or both. This also puts her firmly under tropes such as Yandere, Clingy Jealous Girl, and Psycho Ex-Girlfriend for Duncan.
- It's All About Me: One of her main characteristics. She can want other people for her own ends, and be nice to them to achieve those ends, but she isn't actually capable of caring about anyone other than herself.
- Mrs. Robinson: She looks and acts the part, as she was nearly 50 when she first became Immortal, and has a history of pursuing very new Immortals, as Duncan was at the time and Richie is when she's encountered again.
- Fingerless Gloves: We see he's wearing a pair while threatening the man he's robbing.
- Hellbent For Leather: Kant wears a leather jacket, which Coltec removes after beheading him.
- Politically Incorrect Villain: Mocks the Asian man he's robbing, and refers to Coltec as "Tonto" when he intervenes.
- Small Role, Big Impact: His chance encounter with Jim Coltec leads to a Dark Quickening, which leads to Coltec's death at MacLeod's hands. While under the influence of the Dark Quickening, Duncan murders Sean Burns and comes close to doing the same to Richie. Burns' death will lead to Steven Keane renewing his promise of revenge against Duncan. Richie's fear and disillusionment will lead to him going head hunting, which itself will either directly cause or lead to the deaths of Alec Hill, Gerard Kragen, Carter Wellan and Haresh Clay.
- Beatnik: He's seen doing a poetry reading in front of some beatniks when Duncan goes to confront him.
- Cool Shades: A natural part of his attire among beatniks, considering the crowd he was hanging out with.
- Good Smoking, Evil Smoking: Puffs on a cigarette throughout his performance.
- Hidden Depths: He's a pretty decent saxophone player.
- Offstage Villainy: MacLeod has unstated personal reasons for wanting Korland dead, and Coltec refers to him as a monster. We find out later that his pattern was murder followed by arson, but we never actually see Korland in action.
- Perma-Stubble: Shaving was not high on his list of priorities.
- Pyro Maniac: Arson was an obsession of his, according to what we find out about him.
- Serial Killer: Implied to be one, going by what is said about him.
- Talkative Loon: As seen by his performance in front of beat poets.
- Villains Out Shopping/Kingpin in His Gym: Korland isn't doing anything outwardly villainous when he Mac challenges him, and seems to have been giving such performances for some time. That said, he's clearly reliving his murders onstage, with the implication that all of his poetry is inspired by the crimes he commits.
- Villain with Good Publicity: He's obviously been performing for a while, and has some very loyal fans (his own Watcher seemingly among them).
- Badass Beard/Beard of Evil: Closely cropped in present day, and a much longer one in 1755.
- Determinator: If he sets himself to a goal, nothing is going to get in his way of achieving it.
- Evil Virtues: Kassim is Determined, Dilligent, Patient, Selfless, and above all, Loyal.
- I Gave My Word: In 1480, he swears to ensure that the Al Deneb family will return to power if it takes a thousand years, and he's in no way joking. He holds others to the same standard, calling in a favor from almost two hundred and fifty years past and expecting Duncan to make good on it.
- I Have Your Wife: Kidnaps Rachel MacLeod to goad Duncan into a duel.
- Legacy of Service: Kassim has served the same family, usually from behind the scenes, for over five hundred years.
- Villain Has a Point: Kassim has his own reasons for staging the assassination, but we see that President Hamad is willing to commit murder to maintain his power and, according to Kassim, he's imprisoned and executed five thousand of his own people in the last four years. Wanting to overthrow Hamad in favor of someone less monstrous isn't exactly unreasonable.
A devoutly religious Immortal who came to believe that the god given purpose of Immortals was to battle each other until the Game ended.
- Antagonist in Mourning: Sincerely prays for the souls of those he kills.
- Anti-Villain: Even MacLeod states that Case isn't an evil man, he's merely playing The Game as he understands it, no more and no less than that. There's no sadism in his actions, and he genuinely doesn't enjoy killing.
- Blue and Orange Morality: 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. In the past he defeated a young pupil of Duncan's who had repeatedly challenged him. 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. 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.
- Death Glare: One of the few times Case breaks his deadpan is when Jean-Philippe suggests he enjoy himself with one of the women in the tavern.
- Face Death with Dignity: When offered the choice between death and compromising his beliefs, he doesn't even hesitate.
- It's What I Do: Word of God is he was written to be the embodiment of the phrase. Case plays The Game and nothing else.
- Mission from God: Case believes that all Immortals are on such a mission: they are meant to fight until only one of them is left.
- Nothing Personal: It really, really isn't.
- Principles Zealot: Everything he does revolves around his perception of his "god given" mission. And nothing can sway him from it or convince him to do anything counter to it.
- The Older Immortal: Around a thousand years old.
- The Stoic: Very, very rarely will he break his deadpan expression or raise his voice.
- Straight Edge Evil: Doesn't curse, doesn't drink, doesn't womanize.
- Warrior Monk: Fought in the Crusades.
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.
- Face Death with Dignity: In a deleted scene, he gamely parries a few attacks before deliberately dropping his guard and saying that he's accomplished everything he wanted. In the episode itself, the last thing we see him do is tell his mother that he loves her before turning to face the other Immortal.
- Naïve Newcomer: To The Game.
- Ungrateful Bastard: He interpreted Duncan's reluctance to fight Case (who was after Danny) as a sign that MacLeod wouldn't stop Case from taking Danny's head, so Danny planned to betray Duncan and take Duncan's head to give himself a chance against Immortals who would challenge him.
- It's Personal: Renegade Watchers killed his wife, and now he has declared war on all Watchers.
- Roaring Rampage of Revenge: Horton's group of rogue Watchers kill his wife, and Jacob begins murdering his way through the entire organization.
- Villain Has a Point: He's attacking innocents, but Watchers have turned towards being hostile to Immortals in many different places and eras, and even those not attempting to murder all Immortals as Horton's renegades did have violated their oaths and caused the deaths of Immortals in any number of ways. He has a fair point in not trusting them.
- Blood Brothers: With Haresh Clay.
- Hellbent For Leather: In present day. Richie mockingly calls him Leather Boy.
- The Older Immortal: Over nine hundred at the time of his death.
- Polite Villains, Rude Heroes: While Carter has plenty of attitude himself, he tries to prevent a fight between himself and Richie, repeatedly questions the need for violence, and Richie's insistence on fighting for no reason clearly disturbs him.
- Pretty Boy: His pretty boy looks and long hair makes him stand out and is easily recognizable.
- Villainous Friendship: He spent nearly a millennium as a friend to the head hunter Haresh Clay. Clay was distraught when he learned of Wellan's death.
- Villains Out Shopping: On his way to meet Haresh Clay, he stops in a dive bar and orders a drink. It gets him killed.
- "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."
- Badass in a Nice Suit: Clay likes to dress in fashionable suits in the modern days.
- Bald of Evil: Probably more like "Bald of Moral Ambiguity" but Clay is a relentless headhunter and sports a shaved head.
- Beard of Evil: And a thick beard on top of the shaved head.
- Blood Brothers: With Carter Wellan.
- Due to the Dead: Not only does he attempt to avenge Carter, he also makes sure he gets a burial and a headstone.
- Let the Bully Win: He once have this advice to Carter. When playing darts with a duke, even if the duke in question is half blind, you should lose.
- Noble Demon: While Clay is a ruthless head hunter, he shows respect to those he considers a Worthy Opponent, has polite mannerisms, and remembers and honors the men he's defeated. He also allows a few policemen to take Richie away rather than attempting to kill them all, which he probably could have done.
- Nothing Personal:
- Clay hates Richie for killing Carter but he doesn't particularly dislike MacLeod, and only agrees to fight him after the latter forces the issue. For Duncan's part, it's very personal, as Clay killed his mentor Graham Ashe years before and mocked the young and inexperienced Duncan when Duncan remained on holy ground (as Ashe had requested) instead of going into a Hopeless Boss Fight against Clay in order to avenge Ashe.
- This is his approach to The Game in general. He's not hunting and killing Immortals out of malice, (although he can be a jerk about it, as when he taunted a younger Duncan after killing Ashe) he's just out to win and live. This is put aside in Richie's case though, because Richie went far out of his way to provoke Wellan.
- Not Worth Killing: This was his opinion of a young Duncan, when Duncan was too scared to face him after Clay defeated Graham Ashe.
- The Older Immortal: Over a thousand at the time of his death.
- Soft-Spoken Sadist: He tends to speak in a low voice, often barely above a whisper, often making somewhat wry or philosophical points as he does.
- Villainous Friendship: He spent nearly a millennium being friends with Carter Wellan, and was distraught at Wellan's death,
- Small Role, Big Impact: Myron's got maybe ten lines, and is onscreen for less than a minute. His death kicks off the plot of the episode and completely upends Carl's life.
- The Southpaw: Notes that Carl has a problem hitting against left-handed pitchers and incorrectly thinks this will carry over to their fight.
- Combat Pragmatist: Prefers to snipe his targets then take their heads while they're dead or weakened.
- Harmless Villain: He's an incompetent swordsman, and no threat at all in a fair fight. Word of God is that his choice of sword and fighting style come from old pirate movies.
- In-Series Nickname: Johnny K.
- Professional Killer: A merc/assassin.
- Not Me This Time: Kragen is a murderer, abuses women and caused Alec Hill no end of grief, but he didn't take Alec's head. Played with in that Duncan never explains why he's challenging Kragen, and Kragen seems to take as a given that their duel is revenge for his murder of Hill's wife in 1886.
- Unhand Them, Villain!: A variation. Though Duncan does indeed tell Kragen to "let her go" several times, he doesn't go over the cliff until Alec speaks up.Alec: There's nowhere to go.
Kragen: (glances down into the ravine) Oh yes there is.
- Unknown Rival: It seems to take Kragen a minute to remember MacLeod at first; they met only once, over a hundred years prior, at a moment when Gerard was focused on Alec Hill and his wife.
Col. William Everett Culbraith
- Despair Event Horizon: Implied to have been a decent man prior to his family having been killed in the American Civil War, now he's a bitter nihilist with no care for people.
- Good Scars, Evil Scars: Has scars to go along with a nasty personality.
- Noble Demon: Subverted. The fake Methos points out that Culbraith once had a reputation as a man of honor and decency, before losing his family and being in one war too many. He tries to draw this side out, but Culbraith has long since abandoned that and stopped caring.
- Shellshocked Veteran/Sociopathic Soldier: After he learned of his family's death at the hand of Union soldiers, he allows the Union prisoners of war at the camp he runs to die preventable deaths. When Richie tries to preach peace to him, Culbraith curtly cuts him off by saying "We were made for war."
- Ungrateful Bastard: The fake Methos saved Culbraith's life by invoking Darius' teaching and talking Duncan into sparing Culbraith, at least temporarily. Culbraith later killed "Methos".
- Been There, Shaped History: Was involved with the attempt made by Claus Von Stauffenberg and other conspirators to assassinate Hitler in 1944.
- My Greatest Failure: Not killing Hitler in 1944. After the bomb fails, she pulls a gun but is unable to bring herself to shoot.
- Took a Level in Badass: In 1944, she was a kindly woman who couldn't bring herself to pull the trigger on Hitler. Now she's a cold blooded assassin, trained in the arts of espionage and assassination by multiple intelligence agencies.
- Undead Tax Exemption: A subversion: she claims that her paperwork not holding is why she's being chased by police when she arrives at Duncan's door, but it's really because of her latest assassination.
- Well-Intentioned Extremist: She has decided to kill off anyone who shows potential of becoming a new Hitler type figure before they can ever reach that stage.
- A Pupil of Mine Until He Turned to Evil: Never mentioned on the show, but the Watcher CD Rom says his first teacher was Juan Ramirez, Connor MacLeod's teacher from the first movie.
- Arrogant Kung-Fu Guy: An incredible fighter, and arrogant beyond belief.
- Badass Beard/Beard of Evil: Sports a goatee in 1851.
- Badass Spaniard: His arrogance isn't without foundation; he beats Duncan in 1851 and the only thing that stops Consone from killing him is the offer of something he wants more.
- Disproportionate Retribution: Murders Anna's fiancee (and father of her child). Several years later, he hits her with a car, damaging her legs and ending her dancing career. Twenty-five years later, he seduces and marries Anna's daughter, Luisa, with the intention of killing her. When Duncan brings up the possibility of Luisa leaving him, he shrugs it off and says that he'll kill any man she marries and seduce any daughter that she gives birth to. In between all of this, he never stops mocking Anna or Duncan.
- Dual Wielding: Rapier and dagger.
- Good Smoking, Evil Smoking: Frequently seen puffing on a cigar.
- Hot Blooded Sideburns: He sported them in the '70s, although he's since moved on from the style.
- Master Swordsman: Indisputably. He's one of Duncan's most difficult opponents.
- Sharp Dressed Man: He loves fancy clothes to supplement his slick styles and make him look good.
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 brutally 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 Black and White Morality 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.
- Avenging the Villain: 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 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.
- Black and White Insanity: According to Methos, this is what Keane's worldview is. (And Duncan's too.)
- Cycle of Revenge: In the past, Sean Burns talked him out of this by convincing him the war and its aftermath was essentially a case of Grey and Gray Morality. 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.
- The Dandy/Fashion-Victim Villain: Keane likes his clothes, and he seems to go nowhere in the modern day without a suit and tie on, but he seems deeply 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 eye stabbingly bright.
- Hero Antagonist: 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.
- Honor Before Reason/Revenge Before Reason: 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.
- I Gave My Word: 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 Duncan. 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.
- Interesting Situation Duel: 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.
- Nice Guy: Amanda first encounters him at a club he owns, and the two have a friendly and amiable chat. Things stay that way until Keane starts asking if she's ever heard of someone named Duncan MacLeod, at which point Amanda tries to set him up for an ambush.
- Not So Different: 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.
- Trial by Combat Duncan eventually comes to see their duel as a form of this.
- Unknown Rival: After their first encounter he spent 30 years chasing Duncan around the globe but never actually encountered Duncan because Duncan kept moving on before Keane could catch up. He shows up in the present with a fresh grudge and filled to the brim with righteous anger at Duncan, but to Duncan, Keane is just a random guy he encountered for about a minute 200 years ago.
George Gordon Noel Byron
- "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."
- Addled Addict: Centuries of partying and a couple of decades of Sex, Drugs and Rock & Roll have not done his mind any favors.
- Been There, Shaped History: By virtue of being Lord Byron. Mary Shelley witnesses him being "resurrected" by a Quickening and is inspired to write Frankenstein. Supplemental materials state he was also Jim Morrison.
- Bi the Way: Tries to arrange a threeway with Methos and a barely conscious Mary Shelley.
- Drugs Are Bad: He's an especially anvilicious example of this Aesop.
- Dual Wielding: Fond of using multiple swords.
- Evil Cripple: Never mentioned on the show, but Byron had a malformed right foot which explains why he's so often seen with a cane and likely shaped his choice of weapon.
- Historical-Domain Character: By virtue of being both Lord Byron and Jim Morrison.
- Interesting Situation Duel: He's no match for Duncan in a straight fight... so he shoots Duncan in the leg right at the start and tries to defeat Duncan before the wound can heal.
- Julius Beethoven da Vinci: Byron and Jim Morrison are the same guy. Who knew?
- Nothing Up My Sleeve: Pulls a derringer on MacLeod during their fight.
- Pretty Boy: Verging on long haired pretty boy.
- Sex, Drugs and Rock & Roll: He has been living this life since before rock'n'roll existed. We see him giving poetry readings in the 1800s and indulging in opium and groupies.
- Straw Nihilist: No longer believes in anything, he just wants to create art and party hard.
- Sword Cane: Has used this weapon.
- Toxic Friend Influence: He has a way of being this for Methos and the various mortals he knows.
- Villain with Good Publicity: Walker runs a modeling agency and uses it as cover for a sex slavery operation. He's so good at covering his tracks that even The Watchers don't realize what he's up to at first.
An Immortal who owns a scrapyard and lives with his wife Helen and the mentally challenged Immortal Mikey.
A mentally challenged Immortal with the mind of a child and a deep seated love of trains, he was under the protection of Alan Wells until Wells was killed by Tyler King.
- Ambiguous Disorder: Definitely has some sort of impairment going on.
- Expy: He's essentially Lennie from Of Mice and Men. Huge, mentally challenged individual? Check. Looked after by a smarter, more normal sized person? Check. Accidentally kills a woman? Check.
- Gentle Giant: But he can suddenly become far less gentle.
- Heroic Sacrifice: He realizes how much trouble he's caused Duncan and Ritchie, and voluntarily lays down on some train tracks to end his life.
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.
- Actual Pacifist/Suicidal Pacifism: The man walked it like he talked it.
- Badass Pacifist: At one point he demonstrates that while he believes in peace and relies on his refusal to fight back to cause aggressive Immortals to back down, he's not incapable of self-defense. He tosses Richie around like a rag doll and can use pointed, well chosen words to get even angey and homicidal Immortals to listen to him. Unfortunately, it doesn't work with Culbraith, who has long since stopped caring.
- Horrible Judge of Character: 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.
- Living Is More Than Surviving: 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.Can anyone live for 5,000 years and say they did nothing? Risked nothing? Merely stayed alive with nothing else to show for it? It'd be pointless.
- No Name Given: He's credited as The Messenger, but calls himself Methos. His true name is never revealed.
- Unwitting Instigator of Doom: He comes to town, convinces what Immortals he can to lay down their swords, and moves on to spread his message. Those who come around to his way of thinking tend not to live for very long, as those who wouldn't lay down their swords soon kill them. The stories surrounding this "Methos" are what got Kronos' attention and gave him an area to start searching for his old partner again.
- Nice Guy: He and his mortal wife took Kenny in, thinking they were protecting him.
- Revenge: Kenny killed his mortal wife, and Ross has been hunting him ever since.
