->"''He is Duncan [=MacLeod=], the Highlander. Born in 1592 in the Highlands of Scotland, and he is still alive. He is immortal. For four hundred years, he's been a warrior... a lover... a wanderer, constantly facing other Immortals in combat to the death. The winner takes his enemy's head, and with it, his power. I am a Watcher, part of a secret society of men and women who observe and record, but never interfere. We know the truth about Immortals. In the end, there can be only one. May it be Duncan [=MacLeod=], the Highlander.''"
-->-- '''Joe Dawson''', OpeningNarration from the latter seasons.

''Highlander: The Series'' was the 1992-1997 series that was inspired by the popular ''Franchise/{{Highlander}}'' film franchise. It starred British actor Adrian Paul as Duncan [=MacLeod=], the younger kinsman of the film's central character, Connor [=MacLeod=]. Initially, there was uncertainty as to whether the film character would be recast or a new character created; even Adrian Paul wasn't certain who he would be playing for a time. But the decision was made to develop a whole new character for the series.

The central premise was a bit predictable at times; Duncan would encounter an old immortal enemy, or an immortal friend with someone after him, and the episode would end with Duncan battling his opponent and beheading them. Modern day scenes were interspersed with flashbacks from earlier periods in Duncan's life, usually his first encounter with the [[MonsterOfTheWeek enemy of the week]]. The constant violence did draw criticism at times, and eventually, the networks required that a couple of episodes each season end without a beheading. Even these episodes, however, still usually featured a situation that Duncan could only escape because he was immortal. Unfortunately, these episodes tend to be the least popular of the whole series.

There were some unavoidable {{Continuity Snarl}}s between the films and the series, though many things were retconned to fit in with the series canon. Still, the series managed to be appealing to fans of the film franchise, and it gained a cult following that still exists today.

The series was a French-Canadian co-production, which resulted in Duncan beginning each season in the fictional city of Seacouver, in the Pacific Northwest of North America, either the US or Canada. The name was actually AscendedFanon, the city originally had no name and the FanNickname combining Seattle and Vancouver was eventually adopted. Midway through the season, something would prompt Duncan to travel to Paris, where he would spend the rest of the season. The exception to this was Season 6, which took place entirely in Paris.

Initially, the core cast was Duncan, played by Adrian Paul; Duncan's longtime lover, Tessa Noel, played by Belgian actress Alexandra Vandernoot; and Richie Ryan, a streetwise teen befriended by Duncan after he attempted to break into Mac's antique shop, played by American actor Stan Kirsch. But Vandernoot didn't like the long commutes for the Canada half of the season, and chose to leave the series after season 1, when her father became ill. However, she did return for a two part plot as a Tessa lookalike MagicPlasticSurgery gambit intended to take Duncan out.

The series' other two characters were introduced after Vandernoot's departure. Jim Byrnes played Joe Dawson, Duncan's friend and a member of the Watchers, a secret society dedicated to recording the lives of the immortals they studied. They were forbidden from contacting their subjects, but Joe and Duncan broke the rules and ultimately changed the group forever. Peter Wingfield played Methos, the 5,000 year old legendary immortal who was once "Death" of the Four Horsemen of the Apocalypse, and terrorized Bronze Age Europe. Another recurring character was Duncan's on and off lover Amanda Darieux, the 1,000yr old immortal ClassyCatBurglar whom Duncan once described as a 'bad habit'.

There was a large InternetBackdraft and fan backlash following the death of one of the characters at the end of season 5, and many fans choose to deny the sixth season even exists. It is agreed that the show suffered a big drop in episode quality in season 6, whose episodes were primarily an attempt to find a female character other than Amanda to use in a spinoff. Initially, the character of Alex Raven was to be used, leading to the spinoff being named ''Highlander: The Raven'', but it was ultimately decided to use Amanda anyway.

The series also featured in the fourth and fifth films, ''Film/HighlanderEndgame'' and ''Film/HighlanderTheSource'', neither of which was well received by fans.

----
!!This series provides examples of:

* AboveGoodAndEvil: For some, being alive for centuries can create quite the God complex.
* AbsurdlySharpBlade: Not as bad as some examples, but still crops up on occasion. Duncan has cut cleanly through both another sword and a heavy wooden desk.
* ActionGirl: Amanda, she's a skilled thief and fighter and even has some years as a professional acrobat under her belt. She's also all too quick to rush into danger if it gets her what she wants.
* ActuallyNotAVampire: The episode "The Vampire" features what appears to be a string of vampire attacks in South London in 1840. The victims in Paris all have missing blood and piercing wounds on their neck. There's even a Van Helsing-type character hunting the vampire. He catches him too, [[WrongGenreSavvy only to be shocked when the vampire gets up from being staked]]. Turns out the vampire was immortal Nick Ward, faking vampire attacks so that he could kill his young bride and inherit her money. He drains the blood of his victims with a special hypodermic cane, which leaves bite marks.
* AffectionateNickname: Many of Duncan [=MacLeod=]'s friends refer to him as "Mac" for short.
* AllThereInTheManual: The Watcher Chronicles CD ROM contains a wealth of information about every character seen (and, in some cases, characters only mentioned) on the series. There was also a series of eight novels (a ninth was outlined but never written) that fleshed out certain characters and situations. Both the CD and the novels are canonical.
* TheAgeless: A potential immortal has to die first in order to resurrect, and whatever age they were is the age they remain once they are immortal.
* AlwaysSaveTheGirl: Duncan has this ''bad'' and several people use this against him, [[WhatAnIdiot repeatedly.]]
* AnAxeToGrind: Caleb packs one, and Duncan ends up using it against him in their duel. Kanwulf was very attached to his, and spends three hundred or so years looking for it after Duncan steals it.
* AntiHero: [[KnightInSourArmor Methos]] has survived for millennia by not getting hung up on conventional morality. He is cold and ruthless in his dealings with enemies, but is fiercely protective of those he considers his friends.
* ArcWords: ''"In the end, there can be only one."''
* ArmorPiercingQuestion: When Methos (under his alias of Adam) meets an imposter claiming to be Methos and promoting Immortals to stop fighting, the imposter points out that just staying alive for five thousand years isn't the same as living.
-->'''Fake Methos''': Can anyone live for 5,000 years and say they did nothing? Risked nothing? Merely stayed alive. It'd be pointless.
* ArtisticLicenseHistory: Like the film, the series got the location of the [=MacLeod=] clan lands wrong, and also the chief living in the village with the clan. (Unless Ian was an underchief, which is possible). Also the snowy Waterloo, an unavoidable weather issue during filming.
* TheAtoner: Darius, who went from being a violent general to a priest when he took the head of a holy man and took on some of his goodness.
** Also, Kirin who spent centuries only caring about making money but when his actions led to the massacre of children in Cambodia, he spent the remaining decades trying to make up for his actions.
* BackForTheFinale: Tessa, Richie, Kronos, and Horton all show up in the series finale as part of the ItsAWonderfulPlot so that Duncan sees what would have happened to them if he had never been around. Fitz also returns, taking the role of the guardian angel who shows Duncan why he's made things better for everyone.
* BallisticDiscount: An episode of the series did this with swords. An Immortal walked into an antiques shop that sold assorted bladed weaponry. He asked the proprietor to show him an authentic sword that could stand up to the stresses of combat. The Immortal tested and took a Toledo sword by stabbing the proprietor with it.
* BarbarianLonghair: For the older flashbacks, though Duncan sported it in the modern day too, when it wasn't in a ponytail. He and Connor both had it during their clan days-and the Scots were often considered 'barbarians'/savages by people like the British. Methos and the other Horsemen also sported long hair during the Bronze Age scenes.
* BarehandedBladeBlock: Done in one episode of the series, justified since immortals don't have to worry much about injuries due to their HealingFactor.
* BattleCouple: Duncan and Amanda, both centuries old master sword fighters.
* BeautifulSlaveGirl: Cassandra, when [[spoiler: she's captured by The Four Horsemen and Methos takes her as a slave]]
* BeenThereShapedHistory: Immortality, plus a severe case of ChronicHeroSyndrome, put Duncan in the middle of ''a lot'' of historic confrontations.
* BeethovenWasAnAlienSpy: In "The Modern Prometheus", Creator/LordByron is revealed to have been not only an Immortal, but a pupil of Methos. During a scuffle with another Immortal, Byron was spotted by a drunk Creator/MaryShelley. The sight of Byron healing from his wounds, plus the Quickening which ensued, were [[HistoricalInJoke the inspiration for]] Shelley's ''Literature/{{Frankenstein}}''.
** The Watcher Chronicles CD-Rom lists several other aliases Byron has used over the years. Among them is [[Music/TheDoors James Douglas Morrison.]]
* BigBad: The show usually didn't have these, usually opting instead for [[ArcVillain Arc Villains]] or [[MonsterOfTheWeek Monsters of the Week]], but there were two notable exceptions. Season 2 had [[spoiler: James Horton]], and Season 3 had [[spoiler: Kalas]], although only for a few episodes near the beginning and at the end of the season. [[spoiler: Ahriman]] starts out as this in Season 5 and 6, but [[spoiler: the threat is gone by the end of the second episode.]]
* BullyingADragon / MuggingTheMonster: A 1795 flashback features rookie immortal Jean-Phillipe de Lefaye III, barely 25-years-old, finishing basic training under Duncan and already certain that he can take any opponent. He has a chance meeting with another immortal and immediately challenges him to a duel. He mocks the apparent reluctance of his opponent to fight, his piety, how the man abstains from drinking and wenching. On the first day the other immortal, Damon Case, refuses the challenge. It is implied that he is returning from a battle to the death but Jean-Phillipe does not catch on. On the second day he challenges the man again and is eager for an easy victory. Case accepts the challenge and kills him with minimal effort. It is soon revealed that Case was a c. 700-year-old veteran of the [[UsefulNotes/TheCrusades The First Crusade]] and had a WarriorMonk mentality. All this time the rookie was taunting a much more experienced and deadlier opponent.
* BystanderSyndrome: Methos. He's survived for so long by not getting involved.
* CantLiveWithThemCantLiveWithoutThem: [[HeroProtagonist Duncan]] and [[FemmeFatale Amanda]] have a centuries-long off/on relationship, with her usually showing up when she needs his help to steal something, and him eventually helping her while trying to reform her. They genuinely care for each other, but neither is willing to change.
* TheCaper: Amanda, frequently.
* CassandraTruth: Cassandra, whose initial efforts to get Duncan and Joe to believe her about [[spoiler: Kronos, Methos and The Horsemen]] meet with some extreme doubt.
* ChandelierSwing: "Song of the Executioner"
* ChronicHeroSyndrome: Being harassed by lowlifes? Got an immortal psycho on your case? Want your fence painted?! Just call Duncan [=MacLeod=]!
* ClassyCatBurglar: Amanda.
* ChangelingTale: Duncan's clan believed he was SwitchedAtBirth.
* CombatPragmatist: Methos and a number of the bad guys. Xavier St. Cloud and Morgan D'Estaing were known to use nerve gas and curare to push the odds in their favor, with Xavier later sending gun-wielding mortals after targets. Peter Kanis used attack dogs to soften up his targets before moving in for the kill. Slan Quince had a projectile dagger built into the pommel of his sword. Johnny Kelly was a threat to [=MacLeod=] only because he preferred to use a sniper rifle than engage in a straight-up swordfight. Some, like Andrew Cord, did not have a gimmick and were simply damn impressive fighters who weren't limited by any particular rules or disciplines.
* ContentWarnings: Despite being a syndicated series where censorship is less strict compared to the networks, each episode began with one of these indicating that the show is (slightly) more violent compared to other shows.[[note]]It is based on a series of R-rated movies, after all, so what was seen in the show was as much as they could get away with.[[/note]].
* CoolCar: Duncan's T-Bird.
* CreateYourOwnVillain: It was Methos and Don Salzer's idea to create a database for The Watchers to track Immortals in the modern age. [[NiceJobBreakingItHero Nice job]], guys.
* CrouchingMoronHiddenBadass: Adam Pierson is a mild-mannered Watcher researcher. [[spoiler: He's actually Methos, the oldest living Immortal and formerly ''Death'' of the Four Horsemen from Bronze Age mythology.]] People who know this usually just see him lounging around drinking beer and avoiding fights.
* CulturedBadass: Duncan. In spades! A lover of opera, a reader of poetry, a bit of a gourmand, a lover of fine art, a skilled dancer, a collector of fine antiques, and is qualified to teach history at the college level. He's also fought in Waterloo, the Spanish Civil War, World War II, is trained in who-knows-how-many martial arts, and has survived for 400 years by chopping the heads off of his enemies with a katana.
** Justified - he's had plenty of time to develop all of these skills.
* TheCynic: Methos, making him a foil for idealist Duncan.
* DeadpanSnarker: Methos has probably [[TheFogOfAges forgotten]] more about this trope than most people have learned. I guess living for five millennia has a tendency to make one a trifle cynical. He mellows a bit the more time he spends with [[IncorruptiblePurePureness Duncan]].
* DeathActivatedSuperpower: The first death reveals their immortality and stops their aging.
* DecapitationRequired: What did you think the swords were for? Slicing bread?
* DeliberateValuesDissonance: In the flashback portion of ''Duende'', we see a romance develop between [=MacLeod=] and Theresa, who is newly betrothed to another Immortal. Her intended husband promptly challenges Duncan to a duel. It's pointed out in the episode commentary that the audience is going to automatically sympathize with the couple that is genuinely in love and side against the petty (and, we find, murderous) fiancee . . . but [=MacLeod=] is actively pursuing a woman who is about to be married, and within the society of that time and place, he's absolutely in the wrong.
* DistinguishingMark: When the angered widow of a Watcher Kalas killed wants to expose Immortals to the media, a newspaper publisher naturally doesn't believe it. She shows him a photo of a modern millionaire notable for a facial scar. She then begins showing him images from the Watcher database of a variety of men from World War II to the 1890s to the Civil War and the early 19th century. The publisher is stunned to see that each man bears the exact same scar and realizes they are, in fact, the same man living centuries.
* DoppelgangerReplacementLoveInterest: Lisa Milon.
* DressingAsTheEnemy: Happens in the series finale, when Duncan convinces Methos to take the outfit of an unconscious underling so that they can fool O'Rourke. Methos almost lampshades it with the line "You know, this 'Bad guy just my size' routine never works, [=MacLeod=]. " Less than a minute later, he proves it DOES work, by donning an Irish accent along with the bad guy's coat and shooting the other henchmen.
* TheDrifter: After a while people start to notice that you never get a new wrinkle or grey hair, and it's time to pull up stakes and find a new place in which to settle for a decade or so.
* DroppedABridgeOnHim: [[spoiler:Charlie in the second episode of season four, and [[MurderByMistake Richie]] in the fifth season finale]].
* DrugsAreBad: Appears in the episode "Courage". In the 19th-century, Immortal Brian Cullen wants to run away from his problems and starts using opium. He apparently spend most of the 19th century and 20th century as a drug addict and drug dealer. He resurfaces in the 1990s as an out-of-control menace to society, with his previous good qualities eradicated. He forces Duncan to a duel to the death and has to be put down like a rabid dog. Duncan mourns the good man that Brian was before he started using drugs.
* EarlyInstallmentWeirdness: The first half of Season One set in Seacouver has a few story elements that were later dropped such as the police investigating the beheaded Immortals and the reporter investigating Duncan. Also, episodes featuring Duncan dealing with mortal antagonists that were not The Watchers were gradually reduced after the first season and mostly eliminated by the middle of the show's run, though there were some exceptions in later seasons where the Immortals of the episode were mostly heroic and the villains turned out to be mortals:
** The episode "Unusual Suspects" has Hugh Fitzcairn posing as a mortal businessman and living a life of luxury. Someone poisons him and the rest of the episode deals with a series of murders, as his mortal wife and mortal associates compete to claim his fortune.
** In "Sins of the Father", Duncan suspects that Immortal Alex Raven was behind the assassination of mortal banker George Thomas. It turns out that George was assassinated by his own grandson, in a dispute over the family fortune.
** In "Promises", Duncan is blackmailed by Immortal Kassim to help him in the assassination of mortal dictator Hamad. Duncan spares Hamad's life, and Hamad then murders a rival politician in cold blood. Duncan realizes that he was wrong in giving Hamad a chance and now really wants to assassinate the dictator.
* EnfantTerrible: [[spoiler:[[ReallySevenHundredYearsOld Supposedly]]]] ten-year-old Kenny, whose M.O. is [[spoiler: convincing other Immortals of his helplessness, then taking their heads.]]
* EternalLove: The [=DeValincourts=], for the most part. They were rivals who fell in love and married each other in 1696. They were still married in 1996, though they briefly considered divorce due to boredom with their life. One shared adventure later, they were convinced to stay together and spice up their life a bit more. Others have pointed out to them that [[ArcWords "In the end, there can be only one,"]] but they retort that it's not "the end" yet, and until that time comes, they can still enjoy their lives together.
** Duncan and Amanda have a very long-standing on-again-off-again relationship. As revealed in the episode "Legacy", they first met in 1635. They were still dating each other by 1998. In the romantic comedy episode "Dramatic License", the two confirm that they love each other, but do not dare marry. Duncan asks Amanda how long she could see them spending together, every hour, every day. Amanda realizes that they would get on each other's nerves and end up killing each other. Duncan replies "Exactly my point."
* ExploitedImmunity: One villain used a dark room to blind his opponents while wearing night-vision goggles. Duncan thwarted this by using a lit match to blind the guy long enough to take him out.
* FakingTheDead: When an Immortal can't pass for the age on their ID anymore, it's time to stage an accidental house fire, or just forge a death certificate, and pick a new name and city in which to live.
** Or a person might be killed and their killer will drop his guard, unaware that his victim is Immortal and will resurrect in a few minutes.
** In another variation, an Immortal is killed in front of witnesses. He/she can not return to his/her former life without answering a lot of questions. So they have to run away, leaving people convinced that they are still dead. For example, Richie once had a career as a driver for motorcycle races and became a minor celebrity. He formed a rivalry with mortal rider Basil Dornin. In a serious miscalculation during their last race, Richie caused their motorcycles to collide. He and Basil were killed in front of thousands of people and a television audience. Not only he could not return to his career as a driver, Richie had to avoid anyone who might recognize his face from the news.
* {{Fanservice}}: Duncan frequently went shirtless, and was naked in a bathtub at least once.
** Former Miss America and Playboy model Elizabeth Gracen (Amanda) had her moments, too.
** Tessa served as this in Season 1 and Season 2. Several semi-nude scenes.
** Several of the better-looking male and female Immortals were depicted in scenes emphasizing their good looks and bodies. In "Valkyrie", for example, Immortal Ingrid Henning has a scene where she flirts with Duncan by keeping his attention on her great legs.
* FaceHeelTurn: Methos, during the 'reunion of the Horsemen' arc.
** Pretty much the purpose of the Dark Quickening episodes. As introduced, a good immortal who absorbs too many "evil" Quickenings can be overwhelmed and turn evil. These Immortals can display all the personality traits of long-dead evil foes. The Native American Immortal Coltec, who dedicated his life to clearing the world of evil, had a Dark Quickening. He turned from a Holy Man to a savage, heartless killer. Once Duncan killed Coltec, Duncan himself turned into a villain. He spent some time as a remorseless killer and criminal until Methos managed to purge the evil from him. (The one curiosity was that "evil" Duncan managed to earn an honest wage as a sailor.)
* FlashBack: At least once an episode, giving the audience the history of a certain character. Since Immortals live for so long, many situations they face are in some way [[FlashBackEcho related to events in their past]].
** While Flashbacks take place in almost every episode, their relevance to the present is not always obvious. In "Counterfeit: Part One", the flashback deals with Duncan's brief relationship with an Immortal called Charles Browning. In 18th-century England, Duncan was arrested for poaching and rescued by Charles. He befriended his savior and they spent a night drinking together. It turned out that Charles was a BitchInSheepsClothing, waiting for Duncan to get drunk and weak in order to decapitate him. He miscalculated and lost his own head. The flashback was supposed to relate to the current situation of the episode, not trusting Richie's new friend, but Charles is mostly irrelevant. Both Duncan and Richie had already spent entire episodes with the theme of traitorous friends, so it was not exactly a new lesson.
* TheFogOfAges: Even before meeting him, Duncan has heard that Methos is five thousand years old. Methos tells him that he's actually older, possibly ''much'' older, but "before that, it all starts to blur".
** This is subverted in the Methos Chronicles, showing that he actually remembers his full life and only claims to have forgotten it.
** A few episodes have Methos trying to preserve his old diaries from various centuries. The implication was that he needs written records to keep track of his life.
* GettingCrapPastTheRadar: Although the series is never gory about it, the fact remains that in the vast majority of episodes, one or more characters ends up with his or her head being cut off by the hero. Despite this being a radical escalation from the usual "hero shoots the bad guy to death" level of violence usually seen in action TV shows, this didn't stop the series from being shown on Saturday mornings by some broadcasters (thanks to GoryDiscretionShot, below).
* GoingForTheBigScoop: Randi, the relentless reporter chick in season one's first half. She was determined to learn Duncan's secret.
* GoodGuyBar: Joe's.
* GoodThingYouCanHeal: But lost limbs don't grow back. Injuries to the neck also don't seem to fully heal, such as when Duncan tried to behead Kalas but only succeeded in wrecking his vocal chords. Since Kalas used to be a singer, he's still VERY pissed off about it.
** Later episodes imply that limbs ''do'' grow back... its just that they do it very, very slowly, and the single year between Xavier St. Cloud losing his hand and returning to take revenge on Macleod just hasn't been time enough.
* GoryDiscretionShot: OnceAnEpisode, at least minus the ep or two a season where someone *isn't* beheaded. Absolutely necessary for an otherwise family-friendly series (aired on Saturday mornings in some areas) in which decapitation is actually a core aspect of the concept.
* HandicappedBadass: Joe Dawson, who has no legs and can still kick your ass all day long.
* HealingFactor: Immortals don't get sick, and recover from flesh wounds and broken bones in a matter of minutes. Lost limbs (and heads) not so much.
* HealingSpring: What Methos drags Duncan into at the end of 'Deliverance' so he can battle his bad side and overcome the Dark Quickening.
* HeelFaceTurn: Methos, over the years. He refers to it as "outgrowing my angry adolescence."
* HeelFaithTurn: Darius, formerly a brutal warlord who intended to conquer all of Europe. After taking the head of an immortal holy man, he resigned from the Game and spent the next several centuries living as a humble monk.
* HeWhoFightsMonsters: WordOfGod states James Horton's hatred of Immortals and desire to KillEmAll stems from that fact that he spent most of his career as Watcher to [[PutTheLaughterInSlaughter The Kurgan]], of all people. The conflict between Horton's oath of non-interference and his devout Catholic beliefs eventually drove him to insanity.
* HollywoodSilencer: Subverted to a surprising degree in "Bad Day in Building A" - the silenced weapons sound just as loud as they would without.
* HolyGround: One of the few rules of the Game is that Immortals can not fight on holy ground. What will happen if they violate this rule is left vague. In any case, it does lead to holy ground being one of the few places that they can go to get away from the Game.
** One episode mentions a Watcher rumour that the only known beheading on Holy Ground happened at the Temple of Apollo in Pompeii in August, 79 AD.
* HonorBeforeReason: Duncan suffers from this. A ''lot.'' Methos is frequently the one to call him out on it.
* HookHand: Xavier St. Cloud uses one of these after losing a hand in fight against Duncan.
* HorsemenOfTheApocalypse: They were immortals from the distant past, including [[spoiler:Methos.]]
* HotScoop: Randi [=McFarland=].
* HotterAndSexier: The show never quite shied away from love scenes, but there was one in the DVD/VHS cut of ''Endgame'' that was borderline softcore porn.
* HouseboatHero: Duncan, who keeps a massive barge houseboat in Paris. On the Seine. With a view of ''Notre Dame de Paris!''
* IAmNotLeftHanded: In "The Road Not Taken", a former mentor of Duncan's attacks him while noting that he shouldn't have revealed all of his moves in a previous fight. Duncan replies by executing this trope.
* IAmXSonOfY: Duncan's "I am Duncan [=MacLeod=] of the Clan [=MacLeod=]" is a variant of this.
* IHaveNoSon: Ian [=MacLeod=] does this to Duncan in the 'Family Tree' flashback. Duncan's adoptive mother feels differently.
* TheIdealist: [[KnightInShiningArmor Duncan]] adheres to a very strict code of honor, which gets him into ''a lot'' of tough scrapes.
** The Watchers. They take their responsibility to "observe and document, never interact" with a solemn, almost monk-like devotion. Some fall [[Main/{{Understatement}} a little short]].
* IgnoreTheFanservice: In an episode of Season 3, the villain Kalas holds the beautiful Amanda hostage. She attempts to seduce him and makes sure to show some skin. Kalas casually informs her that he had spend most of his life in a monastery, with the implication that he has been trained to resist temptation. This stops her efforts. This may fit his StoryArc as Kalas has been depicted in several time periods, and he is always depicted as celibate and uninterested in romance.
* ImmortalityBeginsAtTwenty: Averted. Immortals remain the same age as when their first death occurred, which can be from childhood to middle age.
** The Aversion is PlayedForDrama in some cases. The Age you were killed in may leave you in a permanent disadvantage against other Immortals. The Immortal Kenneth/Kenny is 800-years-old, experienced in the Game, with the mind of a jaded old man. His body is permanently stuck at the age of 11, meaning that he is physically weaker than almost everyone, including the rookies.
* ImmortalityHurts: Quite a few times. Though Immortals recover from most injuries, any wound hurts just the same. There was an Immortal who got stranded on a desert island and repeatedly starved to death, one who got buried underwater, one was burned at the stake, one was hanged....
* ImmortalImmaturity: Averted. While some characters are less stuffy than others, when the chips are down, they are all hard-nosed survivors. Even an immortal kid is a [[ManipulativeBastard manipulative bastard]], using his seeming innocence to make people drop their guard.
** Played straight in the case of villain Lucas Kagan. As a pre-immortal Lucas was a homeless street kid, with enough toughness allowing him to beat other kids. He was discovered by Immortal Richard Tarsis, a professional criminal, who decided to raise him. He was trained to be a criminal. When he reached adulthood, Tarsis "killed" him and turned him into an immortal partner-in-crime. Tarsis was killed in combat in 1930 and Kagan was left to his own devices. Some 60 years later, Lucas had all the emotional maturity and impulsiveness of a teenage delinquent. His mantra when anything went wrong or when confronted with his own misdeeds was "It's not my fault". He was blaming Tarsis, anyone else, circumstances. He never learned from his mistakes, never learned additional skills, or managed to accomplish much. He died protesting that he was never given a chance.
* ImmortalityInfertility: Immortals can't have children, period. In one episode Richie is told that he fathered a child before becoming Immortal, but both Duncan and Joe tell him that is not possible either.
** Several Immortals are depicted as adopting children and raising them as their own, as a solution to their need for a family. Several episodes explore PapaWolf and MamaBear reactions when anyone dares to abuse, rape, or kill these children. That the "child" may be an adult with children of his/her own does not seem to matter to the Immortal parent.
* ImprovisedLightningRod: The series uses the Eiffel Tower as one, with Duncan figuring out that he can kill his opponent and the Quickening will travel through the tower to fry the villain's computer before it releases the info on the immortals the villain was using to try to force Duncan to surrender.
* InSeriesNickname: Duncan [=MacLeod=]'s name is often shortened to just "Mac".
* InstantDeathBullet: Tessa in 'The Darkness'.
* JerkWithAHeartOfGold: Methos survives by not getting involved and only looking out for his own interests... most of the time.
* KarmaHoudini: Joan Jett's character in the season one episode "Freefall." The character, called Felice Martén/Felicia Martins, is depicted killing another Immortal's mortal wife and child, to break him psychologically. She later ambushes and kills this immortal. She briefly becomes Duncan's student, in order to get close to him and take his head. He does not want to kill her, so he leaves her unconscious on a beach.
** Kiem Sun in "The Road Not Taken" ends up losing out on the potion he's worked so hard to perfect when Duncan dumps it, but he's still allowed to go free and continue his work elsewhere (at least until he and Duncan run into each other again, in which case Duncan notes that their next confrontation will end with Kiem Sun's death).
** Methos enslaved and raped Cassandra, double-crossed the Four Horsemen, killed Silas (the Horseman and "brother" he liked the most), and has apparently committed raiding and pillaging on a massive scale. He gets away with it, though he claims to have a thousand regrets.
** Benjamin "Benny" Carbassa used his friend Duncan in a plan to save his own skin, hurt and betrayed him, and almost got Duncan killed. Duncan buys him a bus ticket and simply tells him to leave the town.
** David Keogh, the Immortal stalker from the episode "Obsession". His mortal girlfriend Jill Pelentay broke up with him, but he still wanted to marry her. He became seriously obsessed with her, followed her everywhere, broke into her house, and pretty much ruined her life. Jill jumped to her death in order to avoid him. Duncan allows him to go, but Keogh is among the creepiest immortals out there.
** Kenneth/Kenny has double-crossed and often killed anyone who ever tried to help him, including his own mentor/surrogate mother Amanda. He was also hinted to lust for Amanda, and acts rather sadistically towards her when she is trapped. He is allowed to leave unpunished.
** Minor character, but the junkie who killed Tessa counts. Both Duncan and Richie refuse to punish him. He was last seen as a struggling father, but he got away with murder.
* KatanasAreJustBetter: Averted. The katana is Duncan's weapon of choice, but it is never presented as inherently better than any other sword. Also, Duncan has used a wide variety of other swords, including claymore, an arming sword and a rapier/dagger combo.
* KeepTheHomeFiresBurning: The episode "They Also Serve..."
* KilledOffForReal: [[spoiler:Charlie and Tessa and Richie.]]
** Pretty much standard for the series. Heroes and villains, Immortals and mortals, major and minor characters, are killed in almost every episode. Nobody really returns, though a few continue to appear in flashbacks and hallucinations. The Ahriman episodes also had the demon impersonating deceased characters.
** Made explicit in one episode. A rival immortal devoted her life to avenging a killed loved one. Duncan could sympathize, but pointed out that "Nothing you do brings anyone back. Once they're dead... nothing."
* KleptomaniacHero: Arguably Amanda some of the time. She is a professional thief, so many of her episodes involve heists. She is one of the heroes.
* KnifeThrowingAct: Duncan and Amanda do this in the circus in one episode.
* KnightInShiningArmor: Duncan. Sometimes to a fault. His chivalry kept him from killing an Immortal woman even though she killed many other people and tried to kill him.
* KnightTemplar: James Horton: self-styled savior of mortals from Immortals.
* KubrickStare: Duncan pulls one off after being possessed by the Dark Quickening.
* LargeHam: Slan. Duncan, during Darius's death scene.
* LesCopsSportif: During the French half.
* LifeDrinker: Variant. Immortals don't need to suck the life out of people to stay alive, but if they behead another immortal they will absorb their knowledge and skill.
** Several episodes depict Immortals decapitated by mortals, or by machines. The Quickening is absorbed by the Immortal who is closest to the scene. For example, Jacob Galati witnessed his wife Irena getting murdered by mortals and then absorbed her Quickening. There is speculation to what happens where there is no nearby Immortal to absorb a Quickening.
* LivingForeverIsAwesome: For some. There are episodes depicting Immortals having the time of their lives and fully enjoying the opportunities of living through the ages. And there are others which depict Immortals going through traumatic events or experiencing their personal hells.
* LivingADoubleLife: Methos, for a while. He got to experience life as both Methos and Adam Pierson, respectively an elusive Immortal and a well-connected Watcher. Eventually the Watchers discovered than an Immortal has infiltrated their ranks.
* MacGuffin: Many episodes revolve around the seeking of a sacred or mythical object. One of the most elusive ones was the Methuselah Stone, which was sought in several episodes. Legends depicted the Stone as able to grant full immortality to immortals (removing the weakness to decapitation) or even turn a mortal to an immortal. This never went anywhere and seems to have been an AbortedArc.
* MadDoctor: 'Deadly Medicine.' Dr. Paul Wilder (a mortal) is an emergency room physician who secretly abducts patients. He is using them as test subjects in illegal medical experiments. When Duncan is briefly hospitalized following an accident, Wilder discovers his Healing Factor. He kidnaps Duncan in order to experiment on him.
* MadeASlave: Cassandra, and probably a few others, courtesy of the Horsemen.
* ManipulativeBastard: James Horton.
* {{Masquerade}}: The Watchers have two primary aims; to record the lives of the Immortals, and to make sure nobody finds out. The show actually slightly deconstructs the idea of a vast organisation devoted to upholding the Masquerade, since most Watchers treat it like any other job; they even have a pension plan and vacation time. In one episode it's revealed they don't know who killed a recently dead Immortal because his Watcher had taken time off for his sister's wedding when it happened.
* MasterApprenticeChain: Unsurprising in a series where all Immortals have to be trained by more experienced Immortals on how to play the Game. Richie Ryan, one of the main characters, is trained by his mentor Duncan [=MacLeod=] throughout most of the series. Duncan has had several mentors over his life, but the main and original mentor was Connor [=MacLeod=]. Connor appears in a single episode but is mentioned in several others. Connor's own mentor Juan Sánchez Villa-Lobos Ramírez is mentioned in a few episodes, though he is long dead. One episode depicts a character called Graham Ashe as Ramirez's mentor, and Duncan witnesses his death. The Watcher CD mentions Graham Ashe's mentor as Aganesthes of Tiryns, an ancient immortal who mostly appears as TheGhost in the series' supporting material.
** Another chain explored in the series involves secondary but memorable characters. Kenneth/Kenny is considered one of the series' most memorable villains, though he appeared in only two episodes. His mentor and surrogate mother is Amanda, the immortal thief who serves as Duncan's main love interest. Amanda's own mentor and surrogate mother Rebecca Horne appears in two episodes and mentioned in several others. Rebecca's death at the hands of a traitorous student is a StoryArc in the series. The Watcher CD mentions Aganesthes of Tiryns as Rebecca's own mentor.
* MasterSwordsman: Many characters.
* MixedAncestry: Charlie [=DeSalvo=] (half black, half Italian).
* MonsterOfTheWeek: The monster comes looking for trouble, or is threatening somebody else who comes to Duncan for help.
** Even a few episodes who do not depict Duncan have a similar format. "Indiscretions" is a Methos-centered episode. Morgan Walker, an old enemy of Methos, finally locates him after 200 years of searching and antagonizes him until they have a duel.
* {{Mooks}}: The Hunters in ''TAS'', green-armored goons who have [[YouAreNumberSix numbers instead of names]]. They're apparently all descended from the inmates of a pre-war penal colony.
* MoralMyopia: Used twice in "Forgive Us Our Tresspasses." First, in 1746, Duncan, still reeling after the Scottish defeat at the Battle of Culloden, discovers the Earl of Rosemont has sent his troops to crush villages in order to put down any more rebellion. A furious Duncan goes to the Earl's home and grabs his son.
-->'''Earl''': Please, don't hurt my son!
-->'''Duncan''': That is what a thousand Scottish mothers cried out before your soldiers murdered their children.
** Two hundred and fifty years later, the Earl's friend, Immortal Steven Keane, comes looking for payback on Duncan. Duncan realizes that Keane is doing pretty much the same thing Duncan has done several times, settling a score from long ago and they're not that different.
* MuggleMageRomance: Duncan's relationships with mortal women fits the trope. He is a centuries-old Immortal whose HealingFactor and combat skills render him nearly invulnerable. They are typically civilians with no special abilities and vulnerable to aging, illness, and wounds. When they know what he is, their reactions can vary, but they are played for drama. The two most notable mortal lovers, Tessa Noel and Dr. Anne Lindsey, found themselves in the first lines of combat and had their perspectives in life changed.
** The series also explores other dynamics between Immortal and mortal couples, ranging from lifelong bonds and marriages to abusive relationships and mismatched pairings. An unusual pairing involved Immortal Walter Reinhardt and mortal Rebecca Lord. He trained her in sword combat and arranged events to send her against his Immortal rivals, essentially expecting her to fight for him.
* MurderTheHypotenuse: In the episode "The Samurai", immortal Michael Kent discovers that his mortal wife Midori Koto is cheating on him. He confronts her (mortal) lover Akira Yoshida and decapitates him, in the belief that this act would repair the marriage. It doesn't work, and the episode later points out that their love was one-sided to begin with: Michael loved her, Midori never loved him.
* MyGrandsonMyself: Duncan. In one episode, he's seen going to a Paris bank in the 1930's to open up an account he set up a century earlier (and has to remember how many "greats" his "ancestor" was). Obviously, there was a ''lot'' of interest piled up so the bank manager was relieved when Duncan decided to open an account rather than withdraw it all.
** Duncan also pretended to be his lookalike son when he met the aged members of a French Resistance cell he fought with in WWII.
** In the 18th century, Duncan was tutored by a Japanese warrior who was forced to take his own life for honor. Duncan swore that the man's family would always know that if they ever needed help, they could come to Duncan Macleod. 200 years later, the samurai's female descendant comes to Duncan for help and is surprised that Duncan knows of the "family legend." She even says she doesn't expect Duncan to honor a commitment from his "ancestor" but of course, he insists on helping.
** Immortal Katya says that as her adoptive daughter grew, Katya went from her mother to her older sister to her younger sister.
* NeverRecycleABuilding: The characters always find a empty warehouse nearby when they need to fight. While this is usually plausible, there is at least one case when they manage to find one close to the Seine in the center of Paris, in an area where it would need TARDIS-like features to fit.
* NotAllowedToGrowUp: Kenny, a centuries-old immortal in the body of a nine-year old boy.
* NotHimself: Duncan, after the Dark Quickening.
* NotQuiteSavedEnough: Tessa in "The Darkness".
* ObfuscatingDisability: In "The Ransom of Richard Redstone," Duncan has to go to a casino he frequented in the 1970's, run by the same owner. To avoid questions on how he hasn't aged, Duncan dyes his temples grey and walks with a cane and a limp to sell being older like a mortal.
* ObstructiveCodeOfConduct:
** Immortals are only allowed to fight one-on-one, and are forbidden to do so on "holy ground". These rules are [[RetCon malleable]], to put it lightly.
*** Not the "Holy Ground" rule. It's mentioned in series that the one time anyone knows of that immortals dueled on Holy Ground? Was in [[FridgeHorror POMPEII]].
** Watchers are not supposed to interfere in Immortal conflicts. Joe Dawson spends a lot of time bending, breaking, or just plain ignoring this rule.
* OfficeGolf: A mobster in a flashback, who gives the VillainOfTheWeek his first death.
* OffWithHisHead: The only way for an Immortal to die is decapitation, and the Game mostly involves battles to the death.
* OldSchoolChivalry: Duncan has hang-ups about taking the heads of women. He's done it (Nefertiri), but he doesn't like it. He wouldn't kill Kristen in 'Chivalry' and Methos stepped in, saying he was born long before the age of chivalry.
* OlderThanTheyLook: Obviously, just about every Immortal in the series (sans Richie).
** Of special note is that Kenny is over 800 years old but because he died at ten, was able to use the story of being a brand-new Immortal to get in close and take the heads of other Immortals.
** Felicia Martin's MO was to pretend to be a newly made Immortal to learn skills from a "teacher" before taking their head.
** Averted with a few rookie immortals, who are just starting out. Michelle Webster is considered the youngest Immortal in the series, as she was only 18-years-old when last depicted in 1995. Her episode had a lot to do with her bewilderment when surrounded by veteran Immortals.
* OminousLatinChanting: The episode with Damon Case, the immortal who believed they (the immortals) were fated by God to fight, even if the opponent was a newbie. Even his death scene is accompanied by chanting.
* OneLastSmoke: Played straight in the series when Hugh Fitzcairn [[spoiler: is captured by the Hunters]] and as a last request he asks for "A last smoke of my pipe." Horton considers it for a moment before denying him, but the delay buys [=MacLeod=] the time he needs to make it there and [[BigDamnHeroes rescue Fitz]].
* OnlyOneName: In the TV series, the majority of Immortals that Duncan encounters go by one name.
** The Watchers CD added several full names and aliases for them. Kalas, for example, is called "Antonius Kalas". His alias as a singer was "Antonio Neri".
* OutlivingOnesOffspring: Several Immortals in the series have either adopted children or treat their students as surrogate children. The reactions to the deaths of said offspring are played for drama in a few tearjerker episodes. This is also the main plot of the episode "Justice". Female immortal Katya of Greenhill decided to adopt a very young, homeless child called Elena Moreno. The child was adopted in 1958 and Katya made a point of being part of her daughter's life well into adulthood. Elena eventually married wealthy businessman Armando Baptista and had a daughter of her own. In 1996, Armando found out that Elena was cheating on him with his right-hand-man. He killed them both in a blind rage, but managed to be acquitted in a court of law. Katya can not imagine her life without Elena, and pretty much devotes her life to hunting down Armando.
* ParentalSubstitute: Duncan and Tessa, for Richie.
* PastLifeMemories: The immortal variety, since these guys are reincarnated as the same person moments after getting killed.
* ThePerilsOfBeingTheBest: An Immortal famous for either their fighting skills or age winds up drawing the attention of headhunters, Immortals who are serious about winning the game and purposefully seek out old or powerful Immortals in order to defeat them and take their power. This causes most older Immortals, (aside from AxCrazy psychos in the mold of The Kurgan) to learn how to keep a low profile. Some specific examples include:
** Duncan's former friend and MasterSwordsman Brian Cullen, who was once famous for being the greatest swordsman in all Europe. He was challenged so much by both mortal and Immortal foes looking to take the title of greatest swordsman that the deaths he caused took a frightful toll on his psychological well being. Eventually he fled the continent to try to get away from his own reputation, but when he was still challenged after moving to America he descended into deep paranoia and an intense opium addiction which continues into the show's present.
** Methos used to relish combat, fighting, and getting stronger, but he tired of The Game and now loathes getting involved in it at all. He has spent centuries doing everything he can to avoid combat, and also done his best to make sure no one believes in the "legend" of Methos, up to creating spurious legends and stories that contradict his true history and appearance, all so no one can blow his cover ID or track him down.
** One of Duncan's mentors as a new Immortal was a famous swordsman called Graham Ashe. Ashe had lost almost all taste for fighting other Immortals, viewing it more as a chore than anything, and had made appreciating the finer things in life his true passion. When Ashe is confronted by [[TheDreaded the infamous headhunter Haresh Clay]] in Duncan's flashback, he tries to flee before the fight, and after being forced into a confrontation, it's clear that he's no longer up to the sort of intense combat of facing another Immortal MasterSwordsman, even though his life depends on the fight.
** May-Ling Shen, a master swordswoman and martial artist who tutored multiple Immortals including Duncan, was ambushed and killed at a time when she was alone and weaponless, because of a young Immortal who wanted the Quickening of such a famous Immortal.
* PoliceAreUseless: The Police can not stop the crimes of the various immortals, and several mortal villains get away with murder. Due to the various schemes of the Immortals and the Watchers concerning secrecy, the Police is permanently LockedOutOfTheLoop.
* PromotionToOpeningTitles: Elizabeth Gracen (Amanda) and Peter Wingfield (Methos) get this in Season 6, in large part due to Adrian Paul not being able to film every episode and in order to fill the void left by Richie's death (Duncan and Joe were otherwise the only main characters left by that point).
* ProperlyParanoid: Surviving for centuries in a world where nearly everyone like you wants to kill you tends to make one more than a little wary.
** Methos, especially. He probably plans an escape before he ''[[CrazyPrepared makes breakfast]]''.
* PutOnABus: Charlie. Turned into TheBusCameBack...BackForTheDead. Poor Charlie.
* RashomonStyle: The episode "Through a Glass Darkly" features two completely different flashbacks of the same meeting, revealing how two immortals with different perspectives had entirely different recollections of events. In 1785, Duncan and Warren Cochrane, both veterans of the Jacobite risings, arrange to meet Bonnie Prince Charlie in Normandy. Their purpose is to ascertain whether he is willing and able to lead a new uprising. Centuries later, Warren remembers the aging Charlie as a dignified leader who turned down their offer, because he noticed that even his most devoted followers doubted their chances at victory. Throughout the episode, he romanticizes Charlie to a considerable degree. A disillusioned Duncan instead remembers Charlie as a broken man and an alcoholic.
* RealLifeWritesThePlot: The death of Werner Stocker who played Darius towards the end of the first season forced the writing staff to scramble to re-write the series finale without him. This led directly to the creation of the "Watchers" and "Hunters" organisations that would change the direction of the series and feature heavily in future seasons.
** The writers had already planned to kill off Darius in the season finale. The problem was they were planning on shooting scenes of him for the episode. Due to Stocker's death, the scene showing Darius alive was reused footage from a previous episode.
* ReallyDeadMontage: Multiple times, run over either "Dust in the Wind" or "Who Wants to Live Forever".
* ReallySevenHundredYearsOld: Pretty much every immortal. Especially Kenny, though. Most Immortals depicted have lived several centuries, and some are millennia old. The exceptions are the few who were actually born in the 20th century, and are either only in the Game for a few decades, or rookies who are at the start of their careers.
* RearWindowWitness: Tessa in "Eyewitness". She witnesses the murder of fellow artist Anne Wheeler though a window. Initially nobody believes her, because they can not find a corpse. When she is believed, the killer seems to know the police's plan. It turns out that the killer was the Immortal Andrew Ballin, the Chief of Detectives. The Police did not suspect that their boss was the killer.
* RecklessSidekick: Richie, a lot of the time.
* RedPillBluePill: A flashback in the episode "Brothers in Arms" shows that Joe was given this choice in Vietnam by a Watcher, after his first encounter with an Immortal.
* ResurrectiveImmortality: Any normally fatal injury will cause an immortal to die and resurrect completely healed. Drowning, gunshot, hanging, burning, explosion, jump out a window: all minor inconveniences.
** Becomes a bit more inconvenient in the cases of drowning, hanging, starving, etc. In situations like the former two, the immortal may stay deceased until rescued/removed from the circumstances; in the latter, they will constantly resurrect and starve again in an inescapable cycle.
* {{Retcon}}: A minor one, but in Season 1 Duncan runs into Immortal Xavier St. Cloud, whom he supposedly met a few decades prior in what looked like UsefulNotes/WorldWarI. The season 3 finale showed a flashback to a MUCH earlier time, shortly after Duncan became an Immortal, and he runs into Xavier...for the first time. One could argue there was such a long time between their run-ins the pair could have forgotten one another, but considering Immortals seem to remember each other over insane time spans this trope comes into play.
** The producers liked working with Roland Gift hence why St. Cloud is the first evil Immortal to become a recurring villain. And then when the character was finally killed off, the producers brought him back in flashbacks. Roger Daltrey's Hugh Fitzcairn making multiple appearances after being killed off was a similar situation.
* RetiredMonster: [[spoiler:Methos]]. Although the trope is played with as he does regret at least some of his actions, and by the end of the "Four Horsemen" arc, Duncan suspects that [[spoiler:Methos]] manipulated the situation to kill off the rest of the Horsemen. [[spoiler:Methos]] refuses to explicitly confirm or deny this, although he hints that he couldn't kill Kronos by himself. (As he is ''both'' physically and psychologically incapable.)
** Surprisingly enough, [[spoiler: Darius too. He was a warlord before finding religion.]]
** Kage [[EvilerThanThou found people willing to do things even he thought were terrible]] [[TheAtoner and promptly reformed.]]
* {{Revision}}: In the canonical Watcher Chronicles CD, background extras or bit part actors will occasionally be identified as a given Immortal's Watcher. This changes the tone of several scenes considerably but does not affect the plot in any measurable way.
* RiseFromYourGrave: Kanis.
* SafetyInMuggles: Fight called on account of {{Muggles}}.
* {{Samurai}}: One of Duncan's teachers was a samurai, Hideo Koto, from whom Duncan received his katana.
* SayMyName: Duncan in 'The Hunters'. "Dariussssss!"
* ScarsAreForever: While Immortals heal from wounds after they become Immortal, anything before their first "death" remains. Thus, several Immortals bear scars or other marks for centuries.
** The Kurgan was cut on the neck by Ramirez and his neck thus shows a hideous scar, indicating neck wounds don't heal as well as other parts of the body.
** This is added in the TV show as Kalas suffers a slashed throat dueling Duncan in the 1920s. 70 years later, Kalas' once-great voice is now a throaty rasp.
** Xavier St. Cloud had his hand cut off by Duncan in a duel and continues to have a hook for it in his later return.
** This is used by Watcher widow Christine when she tries to prove the existence of Immortals to a newspaper publisher. She shows him images of a variety of men stretching from the early 19th century to a modern-day millionaire. The publisher is jarred to realize that in each photo, the figure boasts the exact same facial scar and realizes they're all the same man using different identities for 150 years.
* SelfMadeMan: It may have come from murdering a priest and stealing a jeweled cross but it's still impressive how in just a few decades, John Durgan went from an illiterate backwoods hunter to a millionaire art expert who spoke six languages.
* {{Seppuku}}: Hideo Koto in 'The Samurai'.
* SelfMadeOrphan: Played with in "Double Jeopardy". The pre-immortal Morgan [=D'Estaing=] was adopted by a French aristocratic family as their intended heir. His adoptive parents eventually had a biological son and daughter of their own. The parents decided to disown Morgan and leave all their fortune to his younger brother Bernard. When Morgan tried to kill Bernard in a jealous rage, their father killed him and had him buried. When Morgan rose as an Immortal, he had a burning desire to kill his whole family. A few years later, he attempted to do just that. But the actual murders, by poisoning, took place at the hands of his mentor and partner-in-crime Xavier St. Cloud. Xavier considered this another lesson on how to become a proper villain.
* ShoutOut: Geraint Wyn Davies guest starred in 'Turnabout' in season 2, during the time he was starring in ''Series/ForeverKnight''. His character on Highlander had a girlfriend named Jeanette, just like his character on the other series, though hers was spelled 'Janette'.
** ''TAS'' has one episode featuring a rogue Hunter who was trying to carve out his own empire and wanted to take an ancient library as his palace and burn all the books. His name? [[{{Fahrenheit 451}} Hunter #451]].
** Kalas, the main villain of Season 3, owns several music-related companies and businesses. A few episodes depict a jazz club which he owns. He chose to name his club ''Film/{{Nosferatu}}''.
** The Watcher's Chronicles CD-ROM was released by the producers of the series to add background information on the major and minor characters of the series. It also introduced a few characters not actually depicted in the series, as mentors or associates of existing characters. An ancient immortal is named "Obelix the Gaul", after the superhuman character from ''ComicBook/{{Asterix}}''. Obelix is mentioned as the mentor of the immortal character Paul Karros, from the series. Karros has mentioned how he fought against the Romans in in the 1st century BC and how he hated them. The Romans happen to be the main villains in Asterix and the comic book series takes place in the 1st century BC.
* ShroudedInMyth: Methos, the eldest living Immortal. [[spoiler: Some of the myths are helped along by Methos to keep people off his trail.]]
* SpiderSense: Immortals can sense when another Immortal is near. This prevents ambushes, but some villains find ways around it.
* StickyFingers: Amanda.
* SoundOnlyDeath: To minimize the gore, we never saw anyone lose their head, only Duncan (or sometimes Methos or Amanda) swinging.
* TheStoic: [[ShellShockedVeteran Darius]] lives a peaceful, secluded life in a monastery, separated from the cares of the outside world and beyond the reach of other Immortals. Duncan often comes to him for advice.
** Methos has survived through the millennia by staying emotionally disconnected and not getting involved in other people's problems.
* SwordFight: OnceAnEpisode, practically.
* SwordPointing
* SwordSparks
* TemporarilyAVillain: Duncan [=MacLeod=], when he has the Dark Quickening.
* TitleTheAdaptation: Was initially called "Highlander: The Series", but later dropped "The Series" part of the name when the show proved to be more popular than the movies.[[note]]Which have since become [[CultClassic cult classics]].[[/note]]
* TrademarkFavoriteFood: Methos is rarely seen without his can of beer. There are rumors he and the Horsemen invented it, but that might just be {{Fanon}}.
* TrueCompanions: Duncan, Tessa, and Richie serve as these in the early episodes, with the former pair practically adopting Richie as their own. As the series goes on, Joe, Methos, and Amanda join and show themselves as being incredibly devoted to Duncan.
* VigilanteExecution: This is what the crowd is intent on doing in 'Innocent Man', until Duncan faces them down and talks them out of it. And the guy wasn't even guilty.
* WakeupMakeup: particularly obvious when Duncan unwraps the mummy of Nefertiri after being unconscious for 2,000 years, and she still has perfect hair and makeup. Note that she also [[AliensSpeakingEnglish knows English]].
* WakingUpAtTheMorgue: Richie once, and several other minor characters
* WarriorTherapist: Sean Burns. At least until Duncan had his Dark Quickening and whacked him.
* TheWatcher: A whole organization of them.
* WaterSourceTampering: In the HorsemenOfTheApocalypse two-parter, the BigBad plans to contaminate water supplies with a bioweapon, ForTheEvulz. The Four Horsemen thrived in the Bronze Age, but are mostly has-beens in the 20th century. Kronos (the Big Bad) wants to orchestrate mass disasters in order to return the world to Bronze Age conditions and allow him to relive his glory days.
* WeGottaStopMeetingLikeThis: In the episode "Judgement Day"
--->'''Methos:''' We've got to stop meeting like this, people will talk.
** And from ''The Sea Witch'':
--->'''Duncan:''' We have to stop meeting this way Alexi. It's been half a century, what will people say?
* WellIntentionedExtremist: James Horton. He considers the Immortals to be monsters and threats to humanity. So he wants to eliminate them all, end the Game, and protect humans. How far he is willing to go for this increasingly makes him a monster.
* WhamEpisode: "The Darkness"; "Comes A Horseman"
* WhoWantsToLiveForever: For some of the characters, anyway. Not to be confused with one of the Queen songs from the film, though it is used when Duncan scatters Darius' ashes in the River Seine, and when Duncan has some Tessa flashbacks.
** Subverted with the montage after Tessa's death. The song used is Kansas' Dust in the Wind rather than the more obvious choice of Who Wants to Live Forever.
* WholeEpisodeFlashback: "The Stone of Scone" and "Unusual Suspects".
* WorthIt: Invoked in "Finale" when the evil Kalas taunts Duncan with knowledge of a computer set up to email out the entire Watcher database to every news agency in the world unless Duncan lets himself be killed.
-->'''Kalas:''' Remember, if you ''do'' kill me, you're finished, too.
-->'''Duncan:''' Maybe it's worth it if it rids the world of you.
* WouldHitAGirl: Methos has no problem killing women. Several other Immortals seem to have no problem targeting women, either Immortal or mortal. Notably averted by Grayson, the warmonger immortal from "Band Of Brothers". At one point, Grayson is all alone in the antique store with Tessa, and she expects him to kill her. She even challenges him to do so. He does not harm her or threaten her at all. He comments: "You are a remarkable woman, well worth keeping alive."
* WouldntHitAGirl: Duncan doesn't like taking the heads of female Immortals. One episode has the Evil Immortal of the Week use this to her advantage. Luckily Methos has [[WouldHitAGirl no such qualms]].
* ZenSurvivor: Methos - "Live, grow stronger, fight another day."
** Given a nasty twist in ''Revelation 6:8''
--> '''Silas:''' Like you always said, Methos: We live, we grow stronger, and then we fight.
