The ''Underworld'' series is a set of horror-action movies revolving around the conflicts of [[FurAgainstFang Werewolves and Vampires]], complete with an AncientConspiracy, an intricate {{Backstory}}, plenty of DarkWorld imagery, great British actors [[LargeHam chewing all the scenery in sight]] and lots of gratuitous gory action.

The main plot revolves around the struggle between the Lycans, a former slave race to the vampires, rebelling and the latter vowing to exterminate them. All because Lucian, a Lycan, and vampire lord Viktor's daughter fell in love and conceived a child. Viktor ordered her killed to ensure the [[HybridMonster "Abomination"]] would not come to term. Lucian escaped and the rest, as they say, is history.

In the modern day, Lycans have been "hunted to near extinction", or so the Vampire nobles think, but in reality they are gathering in numbers and planning on wiping out the vampire leadership with a plot to create their own hybrid on the eve of the vampire elders switching power. This is where Michael comes in. He is, among the descendants of the Corvinus clan, the only one with the genetic makeup capable of letting him be turned into a vampire ''and'' a werewolf. Normal humans can only be turned into one or the other; trying to "mix" causes death. Selene, a vampire Death Dealer with a personal vendetta against all werewolves, notices the Lycan's botched kidnapping of Michael, and helps him escape capture. Along the way, they begin to fall in love, an issue that gets all the more complicated when he gets bitten and starts turning into a werewolf. Can their love survive their species' natural hatred?

The series consists of four movies at the moment with a fifth awaiting release:

* ''Underworld'' (2003) introduces the basic setting, as well as the main characters: Selene and Michael, who are caught in the conflict between Viktor's vampire court and the rebellious Lycans led by Lucian.
* ''Underworld: Evolution'' (2006) picks up immediately where the first movie ended, with Selene and Michael on the run from Marcus, the father of all vampires. Luckily, they are helped by Marcus's immortal father, who is just as interested in stopping him as they are.
* ''Underworld: Rise of the Lycans'' (2009) depicts the origin of the Lycan rebellion against their Vampire masters, sparked by the StarCrossedLovers Lucian and Sonja, Viktor's vampire daughter. [[ForegoneConclusion As may be expected from a prequel, especially by viewers of the first film]], it has a DownerEnding.
* ''Underworld: Awakening'' (2012) is set [[TimeSkip approximately 12 years after]] ''Evolution'' and revolves around Selene, fresh out of torpor, trying to find her and Michael's daughter in the midst of [[TheUnmasquedWorld the extermination of both Vampires and Lycans at the hands of humanity]].
* ''Underworld: Blood Wars'' (2017) is a direct sequel to ''Awakening'' and features Selene and David from that film taking on a new threat. Trent Garrett [[TheOtherDarrin replaces Scott Speedman]] as Michael Corvin.

Not to be confused with ''Film/{{Underworld 1927}}'', TheUnderworld, [[{{Hell}} that underworld]], ''VideoGame/UltimaUnderworld'', the band Music/{{Underworld}}, [[Series/CoronationStreet this one]] or a MetroSpecificUnderworld, which it may loosely reference.

!!The ''Underworld'' series contains examples of:
* AbnormalAmmo: Silver bullets are to be expected, but special liquid silver nitrate bullets are used to prevent the projectiles from being easily removed. The Lycans, for their part, have developed UV rounds for use against the vamps. In fact, the UV rounds came first.
* AbsurdlySharpBlade: Viktor's sword, which Selene uses against him.
* AnachronismStew:
** ''Rise of the Lycans'', in which the vampire nobles (the women, at least) seem to be wearing modern evening wear, some even featuring bare midriffs. The date and setting of the film is inexact, but it is clearly supposed to be a medieval setting (the early 13th century according to the novelizations). This is even more jarring when the vampires are shown alongside their human serfs...who wear attire that's actually fitting for the era.
** The animated shorts have Selene using semi-automatic handguns...in ''1890.''
* AnatomicallyImpossibleSex: Selene and Michael's infamously awkward sex scene in ''Underworld: Evolution''. The way their bodies are positioned, Michael is basically making love to Selene's stomach, though they were sensible enough to photoshop out his penis. This scene is particularly awkward when you realize that Kate Beckinsale is married to the director, who obviously would have been watching the whole time. To quote Mrs. Beckinsale during an interview about this very scene: "...if they move, then itís terribly embarrassing, but if it doesnít move itís terribly insulting and you think theyíre gay. So he lashed it to his leg, tied it in three knots and... I think was in physical torment as well as everything else"
* AncientConspiracy: Both the masquerade setting itself, and ''within'' the vampire clan under the noses of its members.
* AntiClimax: In the first movie:
** A Lycan starts to transform and it looks like it's going to have a knock-down drag-out fight with a vampire. The vampire is quickly knocked down and torn to pieces.
** Raze and Viktor are about to get in a big fight. The strongest vampire and the strongest lycan, Except that when Raze jumps at Viktor, Viktor catches him in midair and breaks his neck.
* AntiVillain: By the end of the first movie, [[spoiler:Lucian]] is a villain only by virtue of being on the opposite side. Unless you're one of the hapless Corvinus descendants he's managed to track down and capture...
* AristocratsAreEvil: The vampires are portrayed as rich aristocrats who live in a mansion and dress in fancy clothes, with their own hired armies. This is in contrast to the Lycans, who were previously their slaves, and now live underground.
* AwesomeButImpractical:
** Selene's automatic pistols. Apart from the required BottomlessMagazines, pistols are too underpowered to reliably stop mere people, inherently inaccurate even when shot one at a time and in Selene's case, don't even produce particularly good results with the in-universe issue of Lycans extracting or pushing out silver bullets. Notable despite RuleOfCool because EVERYONE else uses at least a heavy magnum pistol or submachine gun.
** The silver whips used by Soren. In the prequel, he whips Lucian, who can't fight back, and then when Raze - who ''can'' fight back, and is significantly larger - confronts him in the second movie... [[CurbstompBattle Yeah]]).]]
* BadassBaritone: There are no special effects involved in Creator/KevinGrevioux's voice.
* BadassLongcoat: Vampires and Lycans both wear them, and they have a noted tendency to catch the breeze.
* BadassNormal:
** Raze when still human. First thing he does when confronted with one of the wild and feral Werewolves? Punches the damn thing down.
** Detective Sebastian in ''Awakening''. He may look as if he bought his detective outfit at a Halloween costume store, but when the chips are down he still shoots lycans with a double-barrel over and under grenade launcher and survives a NoHoldsBarredBeatdown from [[spoiler:Jacob Lane in lycan form.]]
** While they get slaughtered by William, the Cleaners themselves are pretty damn badass, considering what they do for a living. They are handpicked by Alexander Corvinus himself, and are selected from the best and brightest in the Special Forces community from around the world, including those of the alphabet agencies that have paramilitary operations. That's nothing to sneeze at. And while we never to get see all of what they do, aside from kicking the crap out of Hungarian Police officers out in the woods; We are given the impression that they've seen action in regards to the Vampires and Lycans, especially with scragglers & other intervening parties from either side.
* BatOutOfHell: The vampire Elder Marcus, on account of his becoming a hybrid, seems to have grown leathery gray skin and enormous, sycthe-like bat-wings.
* BlessedWithSuck: Of the two immortal species, vampires are ''by far'' the weaker. UV radiation is almost instantly deadly, most "normal" physical injuries are still dangerous and Lycan fighting usually results in very high casualties [[spoiler:including an Elder and most of the senior Death Dealers in the first movie]]. Their only edge - and presumably the reason they ultimately won in the first place - is that the Lycan weakness to silver is much more easily weaponized.
* BlackAndGrayMorality: The whole Vampire/Werewolf conflict is more {{grey and gray|Morality}} or black and black. ''Rise of The Lycans'' and ''Evolution'' are the only films where the protagonists can be argued to be the more heroic participants in the conflict, rather than the guys with the current viewpoint.
* BigBad: Viktor in the first movie and ''Rise of the Lycans'', Marcus in ''Evolution'', Dr. Lane in ''Awakening''.
* BoomHeadshot:
** When Selene is escaping in ''Awakening'' a guard shoots her in the head. [[NoSell It just pisses her off.]]
** Lucian is shot in the head (and various other appendages) by Selene in the first movie. It's not much more effective, though it does slow him down a bit.
* BoringButPractical: In the 600 years she's had as a Death Dealer, Selene has learned a lot of brutal, efficient ways to deal with her enemies. She's not one for using flashy moves to deal with her enemies, and when she goes for the kill, She goes for the Overkill. She makes sure you're not going to get back up, much less intact to regenerate. She's the polar opposite of Michael in these regards, as Michael; having no previous combat training, fights in a very aggressive, very animalistic manner, with no solid, reliable technique. Of course, this works for him considering his speed and strength.
* BottomlessMagazines: Zig-zagged. Selene's automatic pistols must just be magical, usually roaring with one continuous noise as they spew bullets like water out of a hose. Her infamous [[BulletHoleDoor Bullet Hole Trap Door]] is only one example. However, her guns ''will'' run out and force her to reload or fight hand-to-hand if it's expedient to the plot.
* BulletHoleDoor:
** Selene makes one through the floor. With ''silver bullets'', no less. ''Series/MythBusters'' attempted to reproduce this specific stunt, and couldn't do it, even with 10 times the ammo. The stunt itself was no picnic. Kate Beckinsale states in the commentary that the shrapnel from the broken floor tile was exploding into her face.
** Inverted with the bottom of a rapidly descending elevator in ''Awakening''. [[spoiler:The elevator lands on her, but the bullets made the floor weak enough (and she's ''tough enough'') that it doesn't particularly bother her.]]
* BullyingTheDragon: Viktor essentially created his kind's worst enemy by treating the Lycans in general and Lucian in particular like dirt until they couldn't take it anymore.
* CallingTheOldManOut:
** Selene in ''Evolution'' to Alexander Corvinus, in response to his NotSoDifferent lecture.
-->'''Selene:''' Everything I've done can be laid at YOUR feet - hundreds of thousands have died because of your inability to accept that your sons are monsters, that they CREATE monsters!
** Sonja delivers one to Viktor regarding his punishing Lucian in spite of the fact that Lucian had just saved her life.
--->'''Sonja:''' Was it not you who told me that I should show a little gratitude in such instances? And what of yourself? Have you no gratitude to one who rescued your daughter?
--->'''Viktor:''' [[SarcasmMode I am awash in it. That he yet breathes shows the depths of my magnanimity.]]
** In ''Awakening'' [[spoiler:Eve to Selene, lamenting how she dreamed of this day, only to be met a cold and distant mother. Selene defends herself by pointing out she just spent 12 years cryogenically frozen, woke up to world she doesn't know, the only man she loved is gone, and discovered a daughter she didn't know she had. She insists her heart isn't cold, it's ''broken.'']]
* CassandraTruth: Selene attempting to warn Kraven and later, Viktor about Lucian being alive.
* CasualHighDrop: At the beginning of ''Underworld'' the vampire Selene is kneeling on the edge of a balcony. She jumps off and falls a long way to the ground, lands on her feet and just walks away.
* CatFight: Subverted in the second film. Twice. In the span of ''[[CurbStompBattle ten seconds]]''.
* CleanupCrew: Alexander Corvinus leads a group of men, appropriately called [[ShapedLikeItself The Cleaners]], who cover up the evidence of lycans and vampires. [[spoiler:They are all killed by Marcus in ''Evolution'', which is what probably led to humans learning of the existence of lycans and vampires in ''Awakening''.]] The novelization explains that all of them come from special forces all over the world.
* ContinuitySnarl: Tannis explains that Viktor didn't kill William out fear of losing his Lycan slaves. But ''Rise of the Lycans'' establishes that the vampires didn't start using Lycans as slaves/daylight guardians until after Lucian was born. Viktor even outright states that Lucian is the first of the Lycans.
* ControlFreak: Adding to Kraven's rather uncomfortably abusive treatment of Selene during the movie, he ''insists'' on apparently knowing where she is, what she's doing, and where she's been at all times.
* CreatorCameo: Raze is played by Creator/KevinGrevioux, who was one of the co-creators of the story.
* CreepyBlueEyes: The vampires and the lycans. The vampires at least only get them when they shift into their "game-face" though.
* CurbStompBattle: Selene versus the two female vamp mooks in the second film. Let's see, you have a Death Dealer with 600 years' worth of experience in killing huge lupine beasts. In the other corner, you have two recently-turned vamps with no combat experience whatsoever whose only purpose appears to be entertainment for their maker. As established in the first and second films, as immortals age, they get stronger.
* CutLexLuthorACheck: Averted. In ''Underworld'', it is mentioned that Vampires have successfully created synthetic plasma, which allows them to sustain themselves without feeding on humans. Selene mentions that the company manufacturing the substitute is waiting for government approval to mass-market it.
* DemotedToExtra: Michael in ''Awakening''. In a more literal sense, he [[TheOtherDarrin isn't even played by]] Scott Speedman.
* DepletedPhlebotinumShells: UV rounds for killing vampires, silver nitrate rounds for killing Lycans.Both are surprisingly effective against armor, considering the liquid cores.
* DidNotDieThatWay: Selene believed that a pack of Lycans was responsible for killing her family. Near the end of the first film, it's revealed that [[spoiler:the true culprit was Viktor]].
* TheDogBitesBack: Literally when Lucian leads the Lycan rebellion. [[spoiler:Lucian himself runs afoul of it when Kraven kills him.]]
* DomesticAbuse: Kraven's treatment of Selene in the first movie runs like an abusive relationship. He's very controlling, demands absolute obedience from her, and is essentially powerless when Selene stands up to him.
* DoNotTauntCthulhu: A silver mine owner in ''Rise of the Lycans'' refuses to pay tribute to Viktor in exchange for clearing his silver mine, as Viktor's forces can barely protect their own lands. Viktor of course kills him for the insult.
* DroppedABridgeOnHim: [[spoiler:Kraven is rather unceremoniously killed by Marcus]], right at the beginning of ''Underworld: Evolution''. A rather mundane death for someone who played a major role in the first film.
* DualWielding: In the first film, one of the vampire lieutenants decides the best way to fight a hulking werewolf in an environment with many projections and obstructions is to uncoil a pair of silver razored whips. [[spoiler:It doesn't work out when one of his whips gets wrapped around one of the projecting pieces of structure.]]. Viktor also whips out a pair of large knives from his sleeves during his battle with Selene. In ''Awakening'', David has a go-at-it, using Soren's silver razor whip and a throwing blade. Surprisingly, He does pretty well with it, until he gets tackled by a Lycan. And of course, Selene and her two pistols.
* EveryHelicopterIsAHuey: Very nearly averted in ''Evolution'' - the helicopter shown in long-shots is a modified SA 360 Dauphin that just happens to [[TheCoconutEffect sound like]] a Huey. Unfortunately, sometime between the helicopter landing and TheSquad piling out the back, it's turned into a Huey anyway. In an apparent compromise, the prop used after it inevitably crashes and turns into a HelicopterBlender looks like some unholy fusion between the two.
* EvilBrit: Seemingly played straight with Lucian in the first film. But then subverted when it turns out [[spoiler: he isn't the villain, or at all evil.]] Viktor on the other hand... And then continued with Marcus in the second film, a Scot with an English accent.
* ExpositionOfImmortality:
** ''Underworld'' mostly employs a combination of dialogue and flashbacks for this. Selene states that she's been a vampire for six hundred years and that Viktor was her maker. Flashbacks in the first and second films show the date for the Lycan-Vampire conflict, establishing Kraven as at least as old as Selene.
** The werewolf doctor in ''Underworld'' has a family tree showing the dates for the Corvinus family dating back to the 5th century AD with Marcus Corvinus.
** And then there's Alexander, who reveals himself to have been the father of the original Marcus Corvinus; still alive after approximately 2600 years.
* {{Expy}}: Thomas in ''Awakening'' is basically a more cowardly, not-as-evil version of Viktor. Creator/CharlesDance clearly took lessons in being Creator/BillNighy for the part -- just listen to his first line -- ''uh.''
* FauxActionGirl: Sonja in ''Rise of the Lycans.'' Despite being the leader of the Death Dealers, Sonja needs almost constant rescuing.
* {{Fanservice}}: Selene's entire wardrobe composes of leather catsuits. The men are lucky -- or villains -- if they get more than pants. Michael almost always fights shirtless, while in the third film, Lucian shows off just about ''everything.''
* FantasticRacism: In ''Underworld'' and ''Underworld Preque Rise of the Lycans,'' the two races of immortals, vampire and werewolf spend entire centuries killing each other over a grudge. The vampires are more typically racist, calling the Lycans (werewolves) animals and vermin and generally hunting them to the brink of extinction. In the feudal era, the vampires kept the Lycans as slaves and pets to guard them during daylight hours. The lead vampire killed his own daughter because she fell in love with a werewolf and carried his child.
* FollowTheLeader: The setting was similar enough to White Wolf's ''TabletopGame/OldWorldOfDarkness'' tabletop RPG that there was a legal fracas over it around the time of the first film's release. Otherwise, the film is generally thought of as ''Film/TheMatrix'' with vampires and werewolves.
* ForegoneConclusion: If you watched the movies in production order, there's no way you didn't know how ''Rise of the Lycans'' was going to end. Watching them in ''chronological'' order, however, takes away the first movie's twist that [[spoiler: Kraven didn't kill Lucian]] as Selene claimed in her OpeningMonologue, and that in point of fact [[spoiler: Lucian isn't actually the villain]]. Either way, you will be spoiled -- though the chronological order can still work okay if you like {{internal reveal}}s.
* GeneticMemory: Carried in the blood of both werewolves and vampires are the "parent's" memories, which can be accessed by drinking.
* TheGhost: Marcus in the first movie. He's only mentioned as one of the three vampire elders, who was supposed to take power before Selene awakened Viktor instead. We don't actually see him until ''Evolution'', where we learn how important he really is to the series' backstory.
* GirlinessUpgrade: Selene in the first few films was rather unconcerned with her appearance, with BoyishShortHair that was also [[MessyHair messy]]. For the fifth film, her hair is now slightly longer and styled more femininely.
* GoodAllAlong: [[spoiler: Lucian, [[WellIntentionedExtremist more or less.]]]]
* {{Gorn}}: There's a scene in ''Evolution'' where an exiled vamp is having a threesome. One of his partners bites him. [[HemoErotic Bleeding just made it hotter]].
* GunsAkimbo: Selene wields almost all her guns, in all three of the films she appears in, in pairs.
* HealingFactor: Both vampires and lycans (except against silver in the latter's case).
** Best illustrated in the second film, when Selene suffers severe burns from short-term exposure to the sun, which are gone minutes later. Both Lycans and Vampires are capable of accelerating their rate of recovery by consuming blood. [[spoiler: Marcus was able to replenish the amount of blood He had used up to accelerate his recovery, by devouring an entire stable full of horses, and Selene was able to heal her head wound and force out a silver bullet, by drinking the blood of an Antigen delivery guard.]]
** In ''Awakening'', the uber-Lycan's super-healing factor is abused by Selene, who [[spoiler:rips a hole in his stomach and leaves an armed silver nitrate grenade inside it, knowing that the wound will heal before he realizes what she did and the grenade will go off before he is able to claw it out of himself again]].
* HighAltitudeInterrogation: In ''Awakening'', while Selene is escaping the lab, a scientist orders his troops not to fire on her, in the hopes of following her to "Subject 2". Later, Selene holds him out a window and interrogates him. After he reveals what he knows, he protests, "I was the one who let you go!" She replies, "[[PreMortemOneLiner I guess this makes us even]]," and [[UnhandThemVillain lets go]] of the scientist.
* HoistByHisOwnPetard:
** Viktor, letting Selene live and turn her into a vampire, because she reminds him so much of Sonja, only to end up [[spoiler:getting killed by his "daughter"]]. In the second film, [[spoiler:Selene rips off one of Marcus's spiked wings and stabs him with it.]]
** Viktor again in ''Rise of the Lycans''. When Lucian is born, he gets the feeling that he should kill the infant, but doesn't, leading to the following exchange:
-->'''Viktor:''' I should have crushed you under my heel the day you were born!\\
'''Lucian:''' Yes, you should have. *stabs Viktor through the mouth* But you didn't.
** Dr. Lane in ''Awakening'' [[spoiler:has his neck ripped out through his throat by the hybrid he created.]]
** The super Lycan in the same film is [[spoiler:doomed by his own HealingFactor. See LuckilyMyPowersWillProtectMe]].
* HumansAreBastards: In ''Awakening''. [[spoiler:Subverted when at least part of the anti-monster purge and subsequent genetic research turns out to be a lycan plot.]] Detective Sebastian in the same movie is also an exception, who's shown to be sympathetic to non-humans. It's later revealed that while his wife had been turned into a vampire, it didn't stop the fact that they still loved each other [[spoiler:until the Feds came around and she elected to step into the sunlight..]]. Contrast overall trope with...
* HumansAreWarriors: Almost as soon as humanity at large discovers the existence of vampires and werewolves, they drive both to the brink of extinction. Selene basically spells out that vampires/lycans have the options of 'run or die.' Standing and fighting doesn't work because modern humanity has been practically ''begging'' for such a foe to unite against. [[spoiler:Except the werewolves successfully infiltrate humanity and become more powerful...so guess it was an option]]
* HybridMonster: Michael Corvin becomes one, specifically the first Half-vampire-half-Lycan. Later, Marcus also becomes one. There's also Subject 2, the daughter of Michael Corvin and Selene created in a lab. Lucian and Sonja's child would have been a straight Vampire-Lycan hybrid if it had lived. Michael started out as a lycan with the dormant Corvinus gene who had the vampire DNA added later. Marcus was the other way around. Subject 2, on the other hand, was born from Michael's already-existent hybrid DNA mixing with Selene's vampire DNA which had already mixed with pure immortal DNA from Alexander Corvinus. These different combinations and scenarios could explain the different appearances of the hybrids.
* HybridOverkillAvoidance: Why there are no hybrids before Michael.
* HybridPower: The overarching story arc of the series is pretty much driven by this trope, though only the fourth movie features a child inheriting both parents' powers--other hybridization instances are carried out via vampiric blood absorption/transmission. To boot:
** Michael Corwin becomes a werewolf-vampire hybrid by getting subsequently bitten by [[spoiler:Lucius, a werewolf, and Selene, a vampire]].
** Selene becomes a [[spoiler:vampire-Immortal hybrid (among other things, rendering her immune to sunlight) by drinking Alexander Corvinus' blood]] in the second movie.
** The fourth movie reveals that [[spoiler:Selene and Michael's daughter inherited both her dad's werewolf strength and her mom's vampiric abilities. Since most of Selene's pregnancy occurred after she became an immortal, it is likely that Eve inherited immortality, as well, making her a ''triple'' hybrid]].
* IdiotBall: Kraven. From slipping up and dropping Lucian's name in argument with Selene to... just about everything else his ego leads him to do.
* IDidWhatIHadToDo:
-->'''Selene:''' It wasn't the Lycans. It was you. How could you bear my trust knowing that you killed my family?\\
'''Viktor:''' Yes, I have taken from you but I have given so much more. Is it not a fair trade for life I have granted you? The gift of immortality?\\
'''Selene:''' And the life of your daughter? Your own flesh and blood?\\
'''Viktor:''' [[BerserkButton I loved my daughter! But the abomination growing in her womb was a betrayal of me and the coven!]] I did what was necessary to protect the species! [[HereWeGoAgain As I am forced to do yet again!]]
* IHateYouVampireDad:
** Played with with Viktor and Marcus in ''Underworld Evolution'', but it has nothing to do with Viktor hating being a vampire. On the contrary, Marcus's bite saved his life, and now Viktor wants all the power of the coven for himself. He even rewrote the vampire history to make himself appear the progenitor and forbade anyone from trying to find the truth. Marcus's hate for his own immortal father has to do with Alexander refusing to accept his sons as they are. Nobody seems to hate being an immortal, despite the drawbacks.
** Played straight with [[spoiler: Selene after she discovers that it was Viktor, not the Lycans, who killed her family]].
* IllKillYou: '' Underworld Rise Of The Lycans'':
--> '''Lucian''':''(to the vampire elders)'' I'LL KILL YOU! ''ALL OF YOU!''
* ImmuneToBullets: Not exactly, but they don't seem to be very effective. Older werewolves can just push them out of their flesh (or skull, in Lucian's case), and vampires seem able to survive all sorts of impalements. In the second film, Selene takes a shotgun blast to the torso without visible injury, and Marcus survives five or six such shots in a row and is only slowed down with minor bleeding. Silver bullets do kill Lycans, but they can heal from it. The silver nitrate liquid rounds kill them very quickly; and the UV bullets are similarly effective against vampires. Marcus can shrug them off ''because he's that tough'', and Selene's corset may be bulletproof.\\
The novelizations [[spoiler: make mention that even though bullets don't do much harm to Vampires and Lycans under normal circumstances, a lot of bullets will harm and kill them. William would more than likely have died from continuous fire delivered from the machinegun mounted on the Cleaners' helicopter, even with his regenerative abilities and size. As tough as they are and even with their regenerative abilities, they're not impervious to sustained gunfire from either small arms or larger.]] With this information in mind, it's no wonder humanity was able to nearly drive them to extinction in ''Awakening''.
* InvincibleHero: Whether you agree that Selene is the 'hero' in the early parts of the series once you find out she's been doing everything based on disinformation Viktor gave her, she fits the 'invincible character' trope very well, as she rarely takes damage of any kind compared to other characters in the franchise, including ''Michael'', who became superfluous as a character seemingly the very minute after Selene kills Viktor. To the point that he doesn't even appear in the fourth film except in flashback being apparently killed, and then found to be frozen in ice. Selene is pretty much unstoppable to begin with, but then she got {{up|ToEleven}}graded to the point that the concern over a Hybrid might as well have been equivalent to being scared of the boogeyman being in your closet when there's an actual armed serial killer loose in your neighborhood.
* IronicEcho: "It's easier if you don't fight it. Trust me." Spoken first by Jacob Lane to Subject 2 in ''Awakening'' as he is preparing to vivisect her. Repeated in the [[spoiler: opposite direction between the same two characters during the final battle as Lane is dying from the fatal wounds inflicted by Subject 2.]]
* JustAStupidAccent: In the first film, Viktor's accent is somewhere between Colonel Kurtz and Colonel Sanders. By ''Rise of the Lycans'', it's a pretty standard English sneer.
* LargeHam: Lots of them, but Viktor takes the cake. Or at least shares it with Kraven. He has his moments in the first, for example coming out of nowhere nasally saying, "What's... this... ruckus?" But in the third, he definitely goes for it. "I whanted to believe your liessss. I KNEW it couldn't be truenotmyowndaughter, ''how could youuu?''"
* LowFantasy: The existence of vampires and werewolves is the only supernatural stuff in the franchise, and there's GreyAndGreyMorality everywhere. The vampires and werewolves do battle with human weapons rather than supernatural powers - with a couple of modifications to target their opponents' weaknesses.
* LuckilyMyPowersWillProtectMe: When Selene is fighting the GiantMook lycan at the end of ''Awakening'', she punches a hole through him [[spoiler:and leaves a grenade inside]] and he announces, as he heals instantly, "I heal instantly!"
* LoveAcrossBattlelines: Sonja and Lucian in ''Rise of the Lycans''. The [[FurAgainstFang never-ending feud]] between vampires and werewolves becomes a full-out war because of Viktor's refusal to accept their relationship.
* LoveTriangle: Kraven thinks he's in one with Selene and Michael in the first film. Also, Erika is in love with Kraven but he only has eyes for Selene.
* MadScientist: The lycans have their own mad scientist, complete with German accent, in the first film. Dr. Jacob Lane in ''Awakening'' also fits the part.
* MadeOfIron: Even with their Healing Factors, Vampires and Lycans have an innate increased durability towards trauma. This is doubly so for the Elders, Hybrids and Selene. Using their SuperStrength, Lycans like Raze can barrel through thick concrete walls without being fazed by doing so, Death Dealers and Lycans alike can both perform incredible drops and leaps without issue, and Selene herself ignores getting shot multiple times in the back (after drinking Alexander's blood) and multiple impacts that would have killed lesser Vampires. She uses this in conjunction with her SuperStrength to tackle a moving van with enough force to flip it. Of course, despite their Made of Iron capabilities and their Healing Factor, they can still die from dismemberment and other forms of massive physical traumas, such as:
## Having their necks cut open, as seen with Sonja fighting against Viktor's elite Death Dealers(not even full on decapitation) and Selene killing Antigen guards with a scalpel.(of course, at that point, any cuts she deals would be equal to being cut open by a full-length sword). Viktor being an Elder, survived having a full-length sword stabbed into his mouth and out the back of his head. He survived an injury that more than likely damaged the top of his spinal column. That's not something you easily walk away from)
## Being impaled by ballista bolts(Its highly doubtful that the Lycans who were hit by those during their escape of Castle Corvinus survived)
## Being hit with explosive force(yes, Trix and Taylor were killed by a silver grenade, but even taking that into consideration, their bodies and everyone else in the ladder chute were gibbed beyond recognition. That grenade was not only loaded with silver, but had more than enough explosives packed into it to render 4 maybe 6 full-grown men into messy chunks)
* MalevolentMaskedMen: The Death Dealers in all incarnations whether its full-face medieval helmets or gas masks. The Cleaners employed by Alexander Corvinus, also wear gas masks whenever they're conducting their Ops, for obvious reasons to avoid contamination and other hazards.
* TheMasquerade: It's revealed in the second film that Sir Derek Jacobi and his merry men have been following the vampires around and cleaning up their mess. They even mention bribing witnesses to keep their mouths shut. [[spoiler:The fact that Marcus kills all of them is probably what led to the BrokenMasquerade.]]
* MeaningfulName:
** Viktor is surprised when putting someone named [[http://definr.com/craven Kraven]] in charge of his household doesn't turn out so well.
** Selene, which means "moon".
** Viktor likes to win, obviously.
* MessianicArchetype: Selene is a rather twisted example, as she is viewed as a traitor by fellow vampires after the first movie. Come ''Awakening'', however, she comes back [[spoiler:from being effectively dead, walks in the sunlight, rallies the younger vampires, and goes around ''resurrecting their dead'']].
* MonogenderMonsters: Going by the movies, there was exactly ''one'' female Lycan, Lucian's mother, who was infected while pregnant.[[note]]However in a FreezeFrameBonus when the hideout of Lucian's pack is first shown at least one of the Lycans hanging around the entrance appears to be a woman.[[/note]] Though presumably the virus is just as contagious to both genders, the use of this trope was {{justified|Trope}} as the vampires wanting only male lycan slaves. There's a few distinct mentions of female Lycans within the novels of the movies.
* MonsterProgenitor: William Corvinus is the Progenitor of all Lycans. Marcus Corvinus, his brother, is the progenitor of all Vampires. Unlike other Lycans, William cannot change back to a human. Marcus, unlike other vampires, is capable of changing form to that of a vampire with bat wings, giving him flight; but only after he becomes a hybrid. The strain of Lycans that retain their sentience and are capable of shifting at will appear to all be 'descended' from Lucian.
* MortalWoundReveal: [[spoiler: Selene's killing blow on Viktor. He actually moves from crouching to standing position and draws sleeve daggers at first - then Selene holds up his sword, covered in his own blood. It only takes a couple more seconds for half his head to fall off.]]
* MundaneUtility: In Awakening, Selene uses her boot knife to as an impromptu key to start and drive a van, and Quint used the powers of PartialTransformation, to transform right hand into a massive set of claws to slice the cables inside of the elevator shaft where Selene and a random Lycan had fallen. Michael uses the same method in Underworld Evolution, to open paint cans to cover up the windows inside of the garage He and Selene took refugee inside of during the day, and even switched over his eyes to see in the dark and brought out of his fangs and claws reflexively. Marcus used his wings to impale and pin people without having to do much of anything else.
* NiceGuy: Lucian seems to be one, one of the first hints [[spoiler: he's not actually the bad guy.]]
* NiceJobBreakingItHero: [[spoiler:Lucian and Kraven were planning to broker a peace treaty between the vampires and lycans before Selene interfered. Marcus also wouldn't have become a hybrid, and humanity wouldn't have found out about the existence of immortals.]]
* NighInvulnerability: Hybrids are TOUGH.
** Marcus, original vampire, has a magazine emptied into his face (courtesy of Selene) and then crushed between a truck and a cliff-side. He shrugs it off. Selene is only able to kill him after impaling him through the head, with his own razor wing, and throwing him into helicopter blades. WordOfGod is that while the HelicopterBlender killed him, he would have recovered from the impaled head. Michael is [[ImpaledwithExtremePrejudice impaled on a pipe]], which does seem to kill; only for him to be OnlyMostlyDead.
** Selene, a vampire immortal hybrid, might actually be indestructible.She survived falling through an elevator shaft while the Lycan who tackled her wasn't so fortunate, and she also survived having a grenade go off near her. She also managed to tackle a van with enough force to flip it a couple of times without any long term damage.
** Not to mention Eve, the daughter of Selene and Michael, whom Selene flat-out states will grow to become even ''more'' powerful than she is.
* NoOntologicalInertia: As the first vampire, Marcus managed to convince the other vampires that killing him would destroy all of them, and killing his brother William (the first lycan) would destroy all Lycans--thus depriving them of their slaves. When Selene hears about this a thousand years or so later, she immediately sees it for the [[SubvertedTrope lie it is]], but the one telling it to her notes that Viktor believed it enough to not risk it. By the time killing William would have been a viable way to take care of the Lycans, Viktor no longer had the key to his prison, so he had no way of testing the theory.
* NotSoDifferent: Alexander Corvinus gives both this and a TheReasonYouSuckSpeech to Selene when she asks him for help killing Marcus. For her response, see CallingTheOldManOut.
-->'''Selene:''' ''(on whether or not Corvinus could have stopped the war)'' Yes!\\
'''Alexander Corvinus:''' Could you kill your own sons?\\
'''Selene:''' You know what Marcus will do! If he finds me, he finds William's prison! You have to help us stop him!\\
'''Alexander Corvinus:''' You are asking me to help you kill my son - YOU, a Death Dealer? How many innocents have YOU slain in your six-century quest to avenge your family? Spare me your self-righteous declarations! You are no different from Marcus and even less noble than William - at least HE cannot control his savagery!
* ObviouslyEvil: Comes up a lot, really. Even more morally grey characters like Selene and [[spoiler: Lucian]] have nothing on the likes of Kraven and [[spoiler: Viktor.]]
* OhCrap: Pierce and Taylor, when the vampires drop a silver grenade into the access tunnel they are climbing up. Quoth Pierce: "Oh shit,".
** Selene and Michael in the ''Evolution'' when they realize that dawn is on the horizon.
** The Super Lycan in ''Awakening'' after [[spoiler: Selene shoves a silver grenade into his stomach]]. Made worse by his pre-mortem BadassBoast.
-->'''Super Lycan''': I heal instantly.
-->'''Selene'''(holding up a grenade pin): I'm counting on it.
* TheOlderImmortal: Alexander Corvinus, the original immortal, who even looks older than the rest.
* OohMeAccentsSlipping: Shane Brolly is Northern Irish, with the effect that Kraven's American accent slips from scene to scene.
* OurVampiresAreDifferent: The vampires are stereotypically pale, blood-drinking, almost completely immortal, highly athletic, and their assassins/soldiers use plenty of GunFu, but the entire condition is supposedly just the result of a mutant [[TheVirus virus]]. They're also not undead, and do not require special things to kill them. For example, sunlight will cause them to burst into flame. However, a stake through the heart is unnecessary; sufficient bullet wounds and similar gore will kill them. They do breathe, but it looks like they've got a substantially increased lung capacity, since Selene was able to hold her breath underwater during their infiltration of William's prison. She was also resuscitated by Michael, during the first movie, and she was shown out of breath. Vampires are also able to reproduce. Similar to ''Film/{{Blade}}'', those born of vampire parents are called "purebloods".
* OurWerewolvesAreDifferent: Caused by the brother strain of the virus, these Weres are large, vaguely humanoid, also immortal, and most can shift at will. Also there are three different "species" of Werewolf in this series. First there's William; the first one to ever exist, who looks the most Wolf-like. Then there's those who are infected by William, known as "1st Generation" Werewolves. Like William, they are unable to return to their Human form ever again. And then there are the "2nd Generation" Werewolves, otherwise known as Lycans. This breed came about when Lucian's mother was bitten and turned into a "1st Generation" when she was pregnant and gave birth to him whilst imprisoned by Viktor. Lucian was born in his Human form and could change between that and his Werewolf form. And when he grew older, Viktor used him to turn more slaves for the Vampires to use, resulting in the majority of the Lycan population. ''Awakening'' features super lycans, enormous beasts at least twice the size of regular lycans, with commensurately greater strength and stamina. They're also immune to silver.
* PartialTransformation: Lucian can give himself fangs to bite someone without fully transforming. Even more practically, the beefed-up lycan in ''Awakening'' can transform his hand to acquire sharp claws. Michael also did the same as well, and Marcus liked using his wings to stab people and pin them in place. Selene used her glowing blue eyes to intimidate a truck driver into leaving his truck.
* PlotHole: The franchise does its best to close these up but they're there if one looks hard enough:
** William was captured in 1202 A.D. It was nearly 200 years later when his prison was completed and the only person credited with building it was Selene's father; just how did Viktor keep William contained for the better part of two centuries?
** Marcus intended to wipe out all vampires and lycans, starting over with William as a super race of hybrids. He has time to bite William and start the transformation, but just doesn't.
* PolarOppositeTwins: Marcus and William were twin brothers, yet wound up as different breeds of supernatural creature. Their viruses interacted with different animal DNA (one is bitten by a wolf; the other - by a bat).
* RazorWings: Marcus uses his wings to impale targets, as well as fly.
* RemovedAchillesHeel: It happens during the climax of Evolution, Selene gains immunity to UV radiation (and thus sunlight) [[spoiler: by drinking Alexander Corvinus' blood and becoming a vampire-Immortal hybrid]].
* ReplacementGoldfish: Kraven, probably accurately, believes that Viktor only turned Selene because she reminded him of his dead vampire daughter. [[spoiler:Which becomes ''really'' awkward when its revealed Viktor killed his daughter, and Selene's family.]]
* ResearchInc: Antigen does medical research in ''Underworld: Awakening''.
* RoaringRampageOfRevenge: Selene does this in ''Awakening'' [[spoiler:first to search for Michael and later to rescue Eve]].
* SafetyInMuggles: It's subverted in the first film when Lycans attack a subway station trying to kidnap Michael. In fact, it's {{Discuss|edTrope}} by the vampires as being a big deal precisely ''because'' it's normally played straight.
* SchrodingersGun: Remember that amulet around Lucian's neck in the first film? It wasn't until ''Evolution'' when we realized [[spoiler:it was [[MacGuffin the key to William's prison]]]].
* SealedEvilInACan: William, in his sarcophagus. [[spoiler:{{Justified|Trope}}, however, in that it was all a trick by Marcus to make sure that the vampires wouldn't kill his brother.]]
* SecretWar: The Vampires and Lycans have been waging one against each other for centuries, unbeknownst to mankind at large save for the occasional rumor or legend. This is thanks to the Cleaners, human spec-ops hand-picked by Alexander Corvinus to make sure that said war is never exposed to the public. [[spoiler:The Cleaners are wiped out in ''Evolution,'' soon making it nigh impossible to keep the SecretWar hidden.]]
* SelfMadeOrphan: [[spoiler:Marcus, and also Selene, if you consider Viktor, the vampire who infected her, to be considered her "father."]]
* SingleLineOfDescent: {{Subverted}}, at least partly. Alexander Corvinus, the originator of the virus, had one human son, who did (in fact) produce plenty of modern-day progeny, if the wall of Xed-out photos is any indication. But the only one of those people still carries his special genes, and happens to also share his last name. LineageComesFromTheFather does seem to ring true, however, as the surnames shown are all variants of "Corvinus", suggesting the Lycans didn't bother tracking the bloodline through any of Alexander's female descendants.
* SlobsVersusSnobs: Werewolves are the Slobs, living in a derelict industrial complex, wearing earth tones, long hair, PermaStubble, and generally being gritty/dirty. Vampires are all pale, wear almost exclusively blacks and reds, are immaculately groomed, beautiful, and live in a decadent Victorian manor... while being arrogant {{jerkass}}es. [[{{Muggle}} Regular humanity]] is shown to be generally somewhere in between, though closer to the Lycans in terms of their conventional, everyman aesthetic. [[spoiler:Coincidentally, this also explains how the Lycans were able to embed themselves with some relatively ease into human society in ''Awakening''.]]
%%* SmugSnake: Kraven. Also Tanis, to a lesser extent, in ''Evolution'' and ''Rise of the Lycans''.
* SourceMusic: The Lycan cops who kidnap Michael pop in a heavy metal cassette to try to drown out his screaming. They leave it on when they go to tranquilize him to keep him from transforming prematurely.
* StairwellChase: In the first film, when the Lycans find Michael and Selene's safe house.
* StyrofoamRocks: In the commentary, the movie's creators point out in a scene towards the end of the movie that some of the stone debris from someone getting thrown through a wall can be seen to float in a pool of water. Oops.
* SuddenSequelDeathSyndrome:
** Apparently [[spoiler:Michael]] in ''Awakening''. [[spoiler:Although it turns out to be a DisneyDeath.]]
** Played straight with [[spoiler: Kraven]] in the same film. He's killed by Marcus almost immediately and forgotten about.
* SuperStrength:
** The vampiric Death Dealers routinely display incredible levels of incredible strength, whether its hitting people with enough force to disable them and throw them like rag dolls, to lifting people up by their necks and leaping all over the place and surviving incredible drops, due to being MadeOfIron.
** Compared to their monstrously strong Lycan cousins, the Death Dealers and most Vampires seem weaker by comparison.
** Elders and Hybrids have been shown to have incredible levels of strength above that. Marcus [[spoiler: was able to pull a goddamn helicopter out of the sky with a small amount of effort, Michael was able to rip off William's head as if it was attached with tape, and Viktor was able to go toe to toe with Michael, only surpassing him due to experience and tenacity. Selene herself got into the action, killing two random Vampires with blows to the head(and into a wall with one of them), being able to go toe to toe with Marcus and winning(due to being infused with blood from Alexander Corvinus) and tackling a moving van like a linebacker.]]
** [[spoiler: Subject 2/Eve]], who's able to ''rip a Lycan's head apart with her bare hands'', all after having gone who knows how long without feeding properly ''and'' suffering a gaping wound in her throat, courtesy of the Lycan.
* SuperSpeed: If Vampires have one thing that puts them above their Lycan cousins, its their physical speed. While Lycans are fast, compared to Vampires, they're nowhere near as fleet of foot. In their Human forms, the Lycans are pretty damn quick, but still marginally slower then Vampires. Selene managed to display her SuperSpeed abilities,[[spoiler: by dodging gunfire and quickly reappearing and overpowering her attacker, and she managed to show this off again, in Awakening; by dodging gunfire and slicing the throats of the Antigen Lycan Guards firing at her.]]
* TakeAThirdOption: It's revealed in ''Awakening'' that instead of hiding from or dying in the hands of humanity at large in the wake of the BrokenMasquerade [[spoiler:the Lycans opted to embed themselves into human society and use non-human prejudice to their advantage against the Vampires]].
* ATasteOfTheLash: In ''Rise of the Lycans'', after capturing Lucian, Viktor subjects him to thirty lashes for betraying his trust, with even one lash being brutal enough to Lucian, and Viktor makes it clear that he wants Lucian to suffer even after the first twenty-one lashes, even forbidding Sonja, his own daughter, from intervening on pain of serious punishment. A KickTheDog moment if there ever was one. Lucian later gets whipped again, by Soren, with Sonja chained to a post and forced to watch before she [[spoiler: is put to death via sunlight]].
* TimeSkip: The twelve years between ''Evolution'' and ''Awakening'', compared to half a night between the first movie and ''Evolution''.
* TookALevelInBadass:
** While Selene was already plenty badass, she becomes even moreso after [[spoiler:taking Alexander Corvinus' blood and becoming a vampire/immortal hybrid]]. Marcus even notes it.
** In ''Awakening'', David goes from a relatively unskilled idealist, to a total badass [[spoiler:after Selene brings him back from the dead.]]
* TransformationIsAFreeAction: Happens in the first movie when a death-dealer simply stands idly by as a Lycan transforms. [[GenreBlind Bad idea]]!
* TrappedInASinkingCar: Selene passes out at the wheel from a loss of blood, sinking into the river together with Michael.
* TreasureChestCavity: Viktor has one half of the key to William's prison hidden inside his chest. (The other half is hanging around Lucian's neck, or at least was in the first film.)
* TheUnmasquedWorld: In ''Awakening'', humans have [[BrokenMasquerade found out about vampires and lycans]] and started hunting down both of them. Selene, while breaking into a sporting goods/gun store, sees vampire and lycan teeth on sale.
* UrbanFantasy: The series genre, with the notable exception of ''Rise of the Lycans.''
* VampireMonarch: Marcus Corvinus is the first of the vampire elders.
* VampiresAreRich: The members of Kraven's vampire clan live in a gigantic mansion, throw extravagant balls and wear gorgeous costumes.
* ViralTransformation: The immortal brothers Marcus and William were turned into monsters by two different viruses, which they then spread to other people.
* WeakenedByTheLight: Several vampires (including one very prominent heroine) meet their maker via this trope throughout the series, especially after the Lycans learned to develop artificial UV light as ammunition.
* WeHaveBeenResearchingPhlebotinumForYears: when Selene tells Michael about the werewolves and the vampires.
* WellIntentionedExtremist: While the kidnapping and experimenting on innocent humans is a little distasteful, [[spoiler:all Lucian was really trying to do was prevent the vampires from exterminating his species]].
* WerewolfThemeNaming: 'Lucian' is a real name with an unrelated etymology, but sounds similar to Lycan, which is a shortening of 'lycanthrope' ('wolf-man' or werewolf).
* WhatHappenedToTheMouse: A retro-active example: Kraven was obviously "cleaning up Viktor's messes" during the time of Rise of the Lycans, which takes place literally ''months'' before Selene's family is murdered, yet he doesn't appear or even get mentioned at all. Heck, even ''Soren'', who has one of the least prominent roles in the series, appears briefly in the prequel.
* WhereTheHellIsSpringfield: The city that the films are set in not only doesn't conform to any one location, but the ''continent'' that it's on can't even be conclusively determined. Characters speak with a mix of American, British and European accents, while the city contains a mix of North American and European characteristics in the vehicles (Mercedes police cruisers alongside large Ford sedans) and architecture. The first movie shows German and Hungarian words in Michael's address, the second movie has Russian or Eastern European cops going after Michael (when he tried to eat normal food) and the fourth movie seems to be set up in either a Future American City or an AirstripOne Expy. Notice that in all movies, vehicle license plates resemble those used in European Union countries sans the country indicator. The novels try to claim that everything takes place in Budapest and the surrounding area. The Russian truck driver in ''Evolution'' was driving home after making a delivery.
* WomanScorned: Erika helps Selene escape the house in the first film once she overhears that Kraven is planning to make her his queen.
* TheWorfEffect: Deliberately used on Selene in ''Awakening'', to show how out of touch she is with the world. When breaking out of Antigen labs in the beginning, she is stabbed in the shoulder, leaps out a window to land painfully on a truck, is thrown from the tuck when the driver hits the breaks, and is then shot in the head by said driver. The enormous lycan is also established as a threat by the way it knocks her around. However, Selene manages to remain a badass in that those things that happen during her escape don't hurt her, as much as they just piss her off; and [[spoiler:she does manage to kill the uber-lycan]].
* WouldHitAGirl: Kraven gives Selene a vicious slap to the face.
** The first thing Viktor does when he arrives on the scene during Lucian's attempt to rescue Sonja...flat out punch her in the face. In the first film, he grabs Selene by the neck and hurls her across a room when he discovers her attempting to turn Michael instead of killing him as she was ordered.
** Aside from Michael, Corvinus, Sebastian, and David, just about every male character Selene crosses paths with has no problem with playing this trope straight.
* WrittenByTheWinners: Viktor rewrote vampire history to appear as if he was the original vampire, when, in fact, it was another Elder, Marcus. While he is quite willing to acknowledge the legend that vampires and werewolves came from the brother Corvinus ("One bit by a bat, the other bit by a wolf"), but he makes fun of it, probably to diminish the connection between Lycans and Vampires. On the other hand, he's quite willing to rewrite [[spoiler:his murder of Selene's entire family]]. Selene [[GenreSavvy shows signs of being aware of this]]. She recognizes that Kraven is not enough of a warrior to have actually killed Lucian, but as the only survivor could claim that he did. She also initially comments that the Lycans started the war, but then admits that that is what is said anyway. By the second film, she's (accurately) assumed virtually everything Viktor has said is a lie.
* YouSexyBeast: Vampires are sleek and seductive, dressing in stylish gothic fashions. Werewolves are brawny, rough-and-tumble men in leather. [[TheyFightCrime They have sex.]]
** Slightly subverted with Michael, who's a human-turned-vampire/Lycan hybrid.
* YourHeadASplode:
** Selene a splodes a Lycan's head above the jaw after [[WrestlerInAllOfUs wrestling one to the ground]] and [[ThereIsNoKillLikeOverkill emptying her gun into his face]].
** [[spoiler: Kraven]] meets his end to Marcus this way.
* ZeroGSpot: In ''Rise of the Lycans'', a vampire and a lycan have gravity-defying sex, hanging off the edge of a cliff.
