Introduced in Underworld
The main protagonist of the series. Selene is a vampire and one of the best Death Dealers in the Fur Against Fang war, believing that her family were slaughtered by Lycans. She was turned by Viktor because she reminded him of his deceased daughter Sonja. She is a skilled marksman and fighter, making her probably the most prominent badass in the series.
She has a change of heart when she falls in love with human-turned-Lycan Michael Corvin, and is responsible for turning Michael into a Hybrid Monster. She finds out that Viktor killed her family, and she kills him by slicing his head in two. In Evolution, she learns her family built William's tomb, hence why Viktor killed them, and becomes a true immortal after drinking Alexander Corvinus's blood, and kills Marcus.
- Absurdly Sharp Blade:
- Selene used one in the first film to slice Viktor's head in two.
- Subverted in Evolution when Selene uses a downed helicopter's propeller to kill Marcus.
- Action Girl: Although, creator Len Wiseman instructed Kate Beckinsale not to use Sarah Connor or Ellen Ripley as a basis for her role; but Officer Bud Wight instead.
- All of the Other Reindeer: After killing both Viktor and Marcus and falling in love with a Hybrid, nearly every other vampire has come after her or (in Thomas' case) shunned her and Blood Wars reveals that Cassius and the current Vampire Council have signed her death warrant.
- It's implied that even before this, she wasn't very popular with the vampire socialites, who appear to look down on her.
- Anti Heroine: Nominal Heroine at first, graduates to Unscrupulous Heroine, or a rather dark Pragmatic Heroine. And descends rapidly back down in the opening sequence of Awakening.
- To be fair, the people she offed turned out to be either Lycans or humans in cahoots with the Lycans who were planning to vivisect her at some point.
- Awesome Moment of Crowning: At the end of Blood Wars, she is made a part of the new Elder Triumvirate, alongside David and Lena. It doesn't involve any crowns (the designation is by drinking blood), but since Elders are the equivalent of vampire royalty, it's basically this.
- Badass Longcoat: Of the leather variety. In Awakening she makes a point to break into a store so she can get a new longcoat. This one isn't made of leather, so she ditches it when she comes across a leather one.
- Battle Couple: With Michael.
- Berserk Button:
- Hurting (or, in Marius's case, killing) Michael won't end well for the person responsible once Selene gets her hands on them.
- Bringing up how her family was killed by Viktor, which Marcus made the mistake of.
- Trying to harm her daughter (see Mama Bear).
- Bottomless Magazines: Played with. She does reload, but not as often as she should.
- Came Back Strong: After being mortally wounded by Marius in Blood Wars, she is put through the same cocooning process used by the Nordic coven and ends up gaining their powers too, best demonstrated when she appears during the final battle killing several Lycans using Flash Step.
- Cassandra Truth: Her attempts to warn Viktor about Lucian possibly being alive.
- Cute Little Fangs: First seen when she bites Michael to make him a Hybrid. Awakening shows the first time she uses them to drain a person, who had just shot her in the head. It heals the wound, and rejuvenates her.
- Dark Action Girl: She's one of the greatest Death Dealers who's ever lived and generally falls in Anti-Hero territory.
- Dark Is Not Evil: She wears black leather clothing and is a vampire, but is ultimately the most heroic character in the series.
- Daywalking Vampire: Becomes this in Evolution by drinking Alexander Corvinus' blood, and thus becoming a Corvinus-Vampire Hybrid.
- Defecting for Love: First she is a merciless Lycan killer, but then becomes a heroic badass and girlfriend to a Lycan.
- Defrosting Ice Queen: Towards Michael in the first movie. And pretty much only towards Michael; the rest of her people skills are somewhere around Viktor's, though she does warm up to David and Sebastian fairly quickly.
- Earn Your Happy Ending: At the end of Blood Wars, which is by far the most optimistic of all the films. While she does lose Michael for good, she gains many new allies and new respect from the vampires now that she is an Elder, plus, the last seconds of the film reveal that she reunites with Eve to possibly live with her permanently, as the Lycans have ceased their hostility, at least for a while.
- Everyone Has Standards: The novelisations reinforce the idea that while Selene is willing to use torture for interrogation, she dislikes the idea of torturing Lycans just for the sake of it, feeling uncomfortable when looking at carvings of Lycans being branded and tortured back in the early days of the war.
- Fanservice: Most of Selene's outfits are made out of leather.
- Flash Step: Develops her speed to this level in Blood Wars by taking on the process used by the Nordic Coven.
- Genetic Memory: Selene has forgotten memories of her life before her family's slaughter, which prove to be a key plot point in Evolution. Justified, she's over 600 years old.
- The Gunslinger: She prefers to fight with guns, though she'll resort to melee weapons, or you know, her bare hands, when necessary.
- Guns Akimbo: Her preferred fighting style.
- Heel Realization: Subverted. By the time she realizes she's been hunting and killing Lycans for a crime they never committed, it's far, far too late for her to do anything other than to keep killing them out of self defense.
- Hell-Bent for Leather: Her outfit is mostly made of leather.
- Hero with Bad Publicity: At least as far as the vampires are concerned; she's renowned as one of finest, if not the finest, Death Dealers ever for 600+ years of defending the Coven and destroying Lycans without relent. Then she falls in love with Michael, a human-turned-Lycan, and kills Viktor and Marcus, two out of the three reigning Elders, and not only is she now shunned by her own kind, they also want her dead. She finally manages to regain their respect at the end of Blood Wars.
- Ice Queen: She defrosts a bit.
- Immortal Heroine: As a vampire she can be killed, until she drinks Alexander Corvinus's blood and becomes a proper immortal.
- Invincible Heroine: She almost never takes any real damage when compared to other characters, up to and including Michael who is supposed to be the ultimate fusion of the two species and was briefly killed before resurrecting, and Alexander Corvinus, from whom she gets upgraded to the point that Michael's hybrid state may as well have been a child's toy compared to Selene's power being equivalent to creating Superman in a lab. She's virtually unstoppable to begin with just in the first film. It just snowballs on from there as she's pretty much a God by the time of Awakening.
- Averted big time in Blood Wars. She gets curb-stomped by Marius and nearly dies.
- Jerk with a Heart of Gold: Increasingly so after the first film. She won't be nice about it, but she'll save the day when she has to.
- Lady of War: Who said gunslinging can't be elegant?
- Like a Son to Me: Gender Flip to Viktor for most of her existence as a vampire, until the events of the first movie.
- Locked into Strangeness: In Blood Wars, she gains white streaks in her hair after getting a power upgrade via the Nordic Coven's cocooning ritual.
- Mama Bear: Though she was surprised to learn she had a daughter, she unsurprisingly becomes very protective of her.
- Meaningful Name: Selene means "moon". Fitting for someone who primarily fights in the night and avoids sunlight.
- Mundane MacGuffin Person: Her family was targeted by Viktor out of fear the Lycans will learn the location of William's prison, since her father was involved in the construction. But Viktor spared her because she reminded him of his daughter.
- Not So Stoic: Usually when it involves someone she cares about. In the first film, she tears up when Viktor accuses her of treason and when he admits that he killed her family, and gets choked up when talking about her family's murder. She breaks down in tears when she thinks Michael's dead and she's nearly an emotional wreck by Blood Wars due to all of the above plus the added anguish caused by Eve running out on her.
- ..and then, just as she's getting better, Maurius taunts her once she learns that Michael is, indeed, dead by his hand and holds out a vial a blood to her, saying it's all that's left of him, going so far as to yank it away when she reaches for it and drink it down right in front of her. Needless to say, her resulting Heroic BSoD, while brief, is very justified.
- Of Corsets Sexy: Selene wears a corset over her catsuit. The sequel implies that the corset has an actual function: being bullet-resistant, which comes in handy when the character gets buckshot straight to the chest. The corset comes away with only minor damage, and Selene just gets pissed off.
- Rags to Riches: Actually, it's from Riches, to Rags, then back to Riches. She goes from being a respected Death Dealer, to a vampire fugitive, then is crowned one of the new Elders. Of course, she lampshades this.
- Really 700 Years Old: According to novelisation, she was nineteen when Viktor turned her...back in the 15th century. She still looks damn good for her age (being played by Kate Beckinsale helps).
- Self-Made Orphan: Subverted. She kills her father figure in the first film, but it was thanks to him that she was already an orphan.
- Star-Crossed Lovers: Selene and Michael, mirroring Lucian and Sonja's romance.
- Super Strength: She had vampire's strength in the first two films but when she drank Alexander Corvinus's blood and became a Corvinus strain immortal vampire, her strength went up higher then before. Notably, she shoulder-checks a van in the third film with enough force to flip it.
- Superpower Lottery: Thanks to drinking Alexander Corvinus's blood, not only she has much more higher inherit vampire powers, but she can endure sunlight and by Awakening, she can pour re-start hearts after cutting open her palm and then re-starting the heart. This is taken further in Blood Wars, where, due to her Mid-Season Upgrade by being cocooned by the Nordic Coven, she develops a Flash Step.
- Violently Protective Girlfriend: Hurting or killing Michael can result in Selene decapitating you or having your body ripped to shreds.
A descendant of Alexander Corvinus, Michael is an ordinary nurse until he becomes the target for the Lycans to create the first vampire/Lycan hybrid. He is turned into a Lycan by Lucian and later is bitten by Selene to heal him from gunshot wounds. This makes him a hybrid, and one of the series' many badasses. He becomes Selene's boyfriend and currently one of two people to still be alive in the series, the other being Selene.
- Battle Couple: With Selene. Only really comes up once or twice in the entire franchise though.
- Big Damn Hero: Immediately following his Back from the Dead moment, he jumps out of an airborne helicopter in time to save Selene by driving his bare arm through a Lycan's torso. If that's not an entrance, I don't know what is.
- Body Horror: Michael's transformation into a hybrid looks quite painful, especially since he seems to switch between Lycan and vampire several times before his body finally gets the balance right.
- Dark and Troubled Past: The car accident and his inability to save his wife, which convinced him to enter medical school.
- Demoted to Extra: He definitely is this in Awakening, seeing as he is practically non-existent in the film aside from one flashback and a single scene where he's shown encased in ice. But one can make the argument that this is also true in Evolution as well, as he's taken out of focus for the better part of the middle-to-latter half of the movie, when he finally pops up again to raise some hell. Though to be fair, he was technically dead for a good part of that.
- Distressed Dude: He needs rescuing by Selene an awful lot; justified in that he's a surgeon with no fighting experience.
- Dropped a Bridge on Him: Selene learns after drinking Marius' blood that the latter has murdered Michael by exsanguination sometime between Awakening and Blood Wars.
- Good Samaritan: Constantly in the first movie, whether it's risking his life to help a woman during a shootout, or saving Selene's life even after she kidnaps him.
- Hospital Hottie: Is a medical intern in the first film, before he goes on the run with Selene.
- Hybrid Monster: He turns grey-blue and he gets black eyes.
- The Lancer: To Selene in the first two films (more so in the second).
- Lightning Bruiser: Becomes one after being turned into a Hybrid.
- Living MacGuffin: In the first movie. His status is revoked entirely by the second film and by the fourth, he's practically non-existent as a character.
- The Lost Lenore: Implied in the theatrical cut, confirmed in the director's cut. His fiancee was killed in a car crash, he became a doctor afterward and moved to Prague (the supposed setting) for a fresh start.
- LEGO Genetics: Michael is the only descendant of Alexander Corvinus who has the same blood type as his, allowing Lucian and Selene to turn him into a vampire/Lycan hybrid.
- Nice Guy: In comparison to the others
- Non-Action Guy: For the majority of the first movie, until he becomes a Hybrid Monster and Took a Level in Badass.
- Not Quite Dead: Michael is seemingly killed by Marcus, but is revealed to be alive.
- Mr. Fanservice: A nice and helpful Pretty Boy who gets tortured multiple times, has a Dark and Troubled Past, and who gets to show his ripped body every time he transforms? Yeah, Selene is lucky.
- Put on a Bus: In Awakening, Michael is seemingly killed, but revealed to be frozen in Antigen's labs, only to escape and disappear.
- Single Specimen Species: Technically the first hybrid ever in the millennium-plus existence of vampires and Lycans (the unborn child of Lucian and Sonja would have been one), until Marcus also turns into a hybrid... then Marcus dies, leaving Michael the only hybrid in existence. If you want to get technical, this also applied when Marcus was still alive, as Michael is a Lycan hybrid, while Marcus was a Vampire hybrid. Whichever way you look at it, Michael is the first and only of his kind. He's not the only hybrid around anymore as of Awakening, but he is the only one of his type of hybrid.
- Star-Crossed Lovers: With Selene.
- Super Speed: Could move fast enough to disappear from Viktor's sight.
- Super Strength: He can tear transformed Lycans to pieces.
- Unfazed Everyman: At first, but it doesn't last long.
- Unskilled, but Strong: When he becomes a hybrid, his unprecedented strength and healing abilities allow him to fight some of the most dangerous beings around. His lack of training bites him in the ass more than once, though.
- Unwitting Pawn: At the beginning of the first film, he has no idea he's being fought over by Lycans and vampires as part of a centuries-long war, at one point even yelling at Selene "What thefuck is going on?" after being attacked by Lycans two days in a row.
- Walking Shirtless Scene: Basically whenever he turns into his Lycan and later hybrid forms, as he rips his shirts to do that (but not his pants). It's particularly notable in Evolution, where he spends 90% of his screen time shirtless.
The first Lycan born with the ability to turn back into a human. Lucian falls in love with Sonja, a vampire, and they become Star-Crossed Lovers. When Viktor finds out, he has his daughter executed via sunlight, kicking off the war between vampires and Lycans. Lucian fakes his death with help from Kraven and spends the next few centuries trying to find a descendant of Alexander Corvinus who has the right blood to create the first Hybrid Monster. He succeeds in turning Michael into one with help from Selene, but is gunned down by Kraven.
- Anti-Hero: Turns out to have been a Type III-IV in the first movie.
- Anti-Villain: By the end of the first movie, he 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...
- Badass Longcoat: Sports one throughout Underworld and wears one in the climax of Rise of the Lycans.
- Barbarian Long Hair: In the prequel. He still has long hair in the original film, but keeps it tied back.
- Big "NO!": When Sonja dies.
- Born into Slavery: As soon as he was born, Viktor killed his mother and raised him as a slave.
- Disc-One Final Boss: For the first movie. At first it seems like he's the instigator of the war, out to exterminate all vampires. As it turns out, he's only after Viktor, who killed his wife and made the war genocidal.
- Eerie Pale-Skinned Brunette: In the original film.
- Evil Brit: At first seemed to be, until it turned out he was a good person. Well, mostly.
- Faking the Dead: For over 600 years.
- Famous Last Words: "You may have killed me, cousin... but my will... is done regardless."
- Forced to Watch: Viktor did this to him, making him watch as Sonja was executed by sunlight.
- Go Out with a Smile: Right before Kraven finishes him, he gets the satisfaction of seeing Selene bite Michael, turning him into a hybrid just as he wanted.
- Healing Factor: His is powerful enough to push silver arrows and bullets out of his body.
- Heartbroken Badass: Due to the death of his lover, Sonja, and their unborn child.
- Incoming Ham: "You are acting like a pack of rabid DOGS!!! And that, gentlemen, simply will not do."
- Large Ham: At times, being fond of Chewing the Scenery, though he's nowhere near as bad as Viktor.
- Monster Progenitor: He's the first of the true Lycans.
- Mr. Fanservice: More so in Rise of the Lycans, where he spends a lot of the film shirtless.
- Nothing Up My Sleeve: He keeps a retractable, mechanical blade up his sleeve.
- Only Sane Man: Only sane Lycan.
- Our Werewolves Are Different: He is the first Lycan born as a human with the ability to turn back into his human form.
- Papa Wolf: Literally.
- Patrick Stewart Speech: His speech to his fellow Lycan slaves fits this trope.
- Punctuated! For! Emphasis!:(crossing over with Chewing the Scenery)
- "WE CAN BE SLAVES, OR WE CAN BE LYCANS!"
- "I'LL KILL YOU! ALL OF YOU!!!"
- "You are acting like a pack of rabid DOGS!!!
- Roaring Rampage of Revenge: Goes on one in Rise of the Lycans after seeing Sonja killed in front of him, complete with actual roaring.
- Walking Shirtless Scene: Rise of the Lycans, good lord.
- Well-Intentioned Extremist: Lucian has killed generations of Alexander's descendants to find one whose blood can mix both Lycan and vampire blood, in order to avenge his dead lover and unborn child. Also, it must be stressed, to prevent the vampires from wiping out his species.
The Big Bad of Underworld and Rise of the Lycans. Viktor is one of the three Vampire Elders, and the foster father of Selene. Having Fantastic Racism against Lycans, Viktor went to great lengths to either control or kill them including killing his own daughter Sonja when she became impregnated with a vampire/Lycan hybrid.
- Badass Longcoat: Wears a fancy one embossed with his personal symbol in the climax of the first film.
- Bait the Dog: When the audience first sees him, he seems to be the reasonable fatherly figure for Selene...only for him to be a manipulative piece of work.
- Battle Cry: In Rise of the Lycans: "KILL THE DOGS!"
- Big Bad: He serves as the primary antagonist in the first movie and the Rise of the Lycans prequel.
- Broken Pedestal: Selene loved him and respected him, but he loses both when she discovers that not only did he execute his own daughter, but he was the one who killed her family.
- Delayed Causality: His death invokes this trope, with him staring blankly at Selene before the top part of his head slips off.
- Diagonal Cut: His cause of death.
- Dual Wielding: After losing his sword he whips out a pair of hidden daggers from his sleeves. Subverted as he never gets to use them.
- Fantastic Racism: Viktor despises the Lycans, and considers a hybrid to be an abomination.
- Faux Affably Evil: He acts benevolent and fatherly toward Selene, but it's just another one of his endless manipulations.
- Hidden in Plain Sight: Viktor hid the keys for William's tomb in plain sight, one being a necklace owned by Sonja, and the second hidden inside his own body.
- Hoist by His Own Petard: Viktor's plans keep coming back to hit him in the face. He creates an army of Lycans; they rebel. He kills Sonja and her child; Lucian swears revenge and makes a new hybrid. He turns Selene into a vampire; she kills him. Even the sword that Selene used to kill Viktor was Viktor's.. What a tangled web we weave.Marcus: I knew Viktor made a mistake by keeping you as a pet. He should have killed you with the rest of your family.
- I Did What I Had to Do: Subverted. Viktor may claim he was doing what was best for the coven, but every last one of his actions (deceiving Marcus, imprisoning William, killing Sonja, murdering Selene's family and turning Selene into a vampire, etc.) directly or indirectly leads to the vampires being all but wiped out by the fourth movie.Viktor: I loved my daughter! But the abomination growing inside her womb was a betrayal of me and of the coven! I did what was necessary to protect the species, as I am forced to do yet again!
- Idiot Ball: He pretty much ran with this one (see above), but punching Singe to death and not having his bleeding body immediately removed will forever be a classic due to his blood dripping into Marcus' tomb and inadvertently turning him into a hybrid.
- I Hate You, Vampire Dad: Sonja and Selene both suffer this. Viktor is shown to be none too happy about killing Sonja. He wasn't all too happy about possibly having to kill Selene, either. His immediate reaction after hurling her halfway across a room, for instance...
- Large Ham: Possibly the hammiest character in the whole franchise.
- Lawful Evil: Pretty much his defining trait. He'll enforce the letter of the law obsessively, even if it makes no sense and results in him killing people he cares about.
- Long-Lived: One of the older (if not quite the eldest) vampires, and also one of the strongest.
- Manipulative Bastard: Viktor managed to fool all the vampires into thinking that he is the first vampire in existence, imprisoned William for all time and went to extra lengths to ensure Marcus couldn't stop him — which failed spectacularly. Not to mention making Selene think her family was killed by Lycans for 600+ years.
- Monster Progenitor: Subverted. Marcus was, in fact, the first Vampire, but Viktor rewrote history to make him appear as the progenitor of the species, a secret he fiercely guarded for over half a millennia.
- Nice Job Fixing It, Villain!: Two instances- killing Sonja was what started the war in the first place. Not believing Selene results in his worst fear being recognized in the form of a hybridized Michael Corvin and his death.
- Never My Fault: He has his own daughter put to death, then has the nerve to blame Lucian for it.
- Offing the Offspring: Twice over, since he kills his only child and his unborn grandchild. Then he has the audacity to accuse Lucian of doing the deed to his face, knowing damn well that Lucian witnessed the murder himself and, being physically chained, was unable to even touch her.
- Overarching Villain: For the first three installments, as the Big Bad of the first film and the prequel, and being an integral part in the backstory of Marcus in Evolution.
- Parental Substitute: Was this to Selene for centuries, until the first movie.
- Screw the Rules, I Make Them!: He helped make the law that vampires can't feed on humans, but he himself regularly broke the law and gorged on human blood, Selene's human family being among his victims. Either subverted or a convenient coincidence, since Selene's father was the only one besides Viktor himself who knew about William's prison.
- Smug Snake: He's extremely arrogant and, while badass, is not unstoppable, and his own depraved actions end up causing his death.
- The Starscream: To Marcus in the past; he overthrew the man as the most powerful of the Elders and proceeded to deceive everyone afterward.
- Strong and Skilled: Viktor is a Vampire Elder, making him stronger than a normal vampire, as shown when he effortlessly lifts a fully transformed Lycan up by the throat and then snaps its neck, all with one hand. He's also a warlord with centuries of combat experience, best shown when he faces off against the newly hybridized Michael Corvin; while Michael is stronger and faster, Viktor's superior fighting skills soon allow him to turn the tide.
- Super Strength: As an Elder Vampire, he's a fair bit stronger than regular vampires and Lycans, as shown when he does a Neck Lift on a transformed Lycan, which leads into a Neck Snap. He can even match the hybridized Michael Corvin, though Corvin is a lot faster.
- Ungrateful Bastard: Anyone who has helped Viktor has ended up paying for it.
- Marcus comes to Viktor while the latter is on his death bed and grants him immortality. How does Viktor repay him? By wresting control of the coven away from Marcus, indefinitely imprisoning Marcus's brother, and having the vampires' history rewritten so that Viktor, not Marcus, is the first and most powerful of the vampires.
- Lucian transforms into Lycan form to save Sonja from becoming werewolf kibble. Viktor's response to this is to have him publicly flogged to near-death for removing the slave collar that would have prevented said transformation. Mind you, he gave Sonja a brief lecture earlier about showing gratitude to Lucian for saving her life. When she calls him on it, he responds that letting Lucian live is his gratitude... then decides to have Lucian killed anyway as a cautionary tale to any would-be upstarts.
- Selene potentially all but saved Viktor, and the coven, from certain doom by breaking the Chain and making him aware of her concerns. After literally centuries of her Undying Loyalty to him, Viktor refuses to hear any of it and orders her judged (which would almost certainly result in her death). After Selene acquires undeniable proof for her suspicions, Viktor refuses to absolve her unless she kills Michael, who's totally innocent and only the "enemy" by being turned against his will.
- Villain Has a Point: Regarding William needing to be stopped. To an extent, preventing the birth of a hybrid could count as well, considering all the trouble that the mere possibility of creating one ended up causing. Marcus and Maurius do absolutely nothing to prove him wrong after transforming themselves into full-blown hybrids.
- Villain with Good Publicity: Even as late into the series as Blood Wars, Viktor is still remembered in-universe as the oldest and most powerful vampire, despite earlier films having established that this was a lie and that he was a belligerent tyrant who used subterfuge and violent coercion to gain his status and wasn't above killing his kind, even his own daughter, in order to maintain it, all the while claiming he was acting for the greater good of the Coven.
- Weak, but Skilled: In comparison to the hybridized Michael Corvin. While Michael clearly outmatches Viktor in sheer strength and initially has the upper hand, Viktor, having 600+ years of combat experience under his belt, eventually manages to turn the tide, with Michael only being saved by Selene making a Conveniently Timed Attack from Behind.
- Well-Intentioned Extremist: In his view, everything he did was to protect the species and the coven. It really doesn't hold water, given his cruelty, his prejudice against werewolves, and his ultimately leading the coven to their doom.
The second of the Vampire Elders. Hardly anything is known about her, making her a bit of a Flat Character. However, she aided Marcus and Viktor in catching William and sided with Viktor to imprison him forever. She has since been revealed to have been the lover of Thomas and the mother of his son, David.
- Et Tu, Brute?: She aided Viktor in imprisoning William as a result of his rampages, despite Marcus wishes.
- Helmets Are Hardly Heroic: At some point during the investigation of the village in Evolution, she removes her helmet but after the Lycans begin to turn, never sees the need to put it back on. They don't seem to do much, though, so it may be that she preferred the added range of vision.
- Lady of War: She's an extremely elegant Vampire Elder and a Badass.
- Missing Mom: Blood Wars revealed she's David's mother, which eventually makes him the last true heir of the Eastern Coven bloodline and therefore supreme ruler of the vampire council.
- Token Good Teammate: She seems to have been this to the other two Elders (although part of this may be due to her brief appearance not providing much information), working to imprison William Corvinus to stop his rampages with the others, focusing on building new covens over trying to hunt the Lycans and not displaying the disregard for human life that Viktor and eventually Marcus have.
- We Hardly Knew Ye: In her first scene in Underworld, she gets whacked by Lycans. She has a slightly larger role in the prologue of Evolution, but is more of a background character until Blood Wars, where, despite being dead she becomes central to the plot due to being revealed as David's mother.
- With Friends Like These...: Hinted at with her relationship with the other two elders, between Marcuss resentment over the other two defying him by keeping William locked away and Viktors escalation of the vampire-Lycan feud Given that she took steps to hide the birth of her son from them.
The third Vampire Elder, and son of Alexander Corvinus. He was bitten by a bat and became the first vampire. With his Lycan brother William out of control, Marcus recruited Viktor, Amelia and their army to catch his brother, only for Viktor to double-cross him and take control of the vampires and imprisoned William forever. In the second film, he is turned into a hybrid and vows to free his brother and rule the world with a new series of hybrids.
- Angsty Surviving Twin: Is this for a short time, as he gets killed not long after William's death, but that scream he does when William dies is proof enough.
- Affably Evil: While he gets the idea to rule the world with hybrids, his main goal is to reunite with his beloved brother.
- A God Am I: Intends to create a new race of immortals, with himself as their God.
- Ascended Extra: Literally given that his presence in the first film is simply as an emancipated figure inside of a coffin waiting to be reawakened.
- Bat Out of Hell: He has large bat wings in his hybrid form. Whether or not he had these beforehand is unknown.
- Big Bad: In the second movie Underworld: Evolution, he seeks to unleash his brother from prison and create a new species of immortals.
- Blood Brothers: Marcus and William have a strong bond. They had a third brother who was only human and presumably died years ago.
- Even Evil Has Loved Ones: When he awakens and learns that it's possible for his bloodline to become hybrids, the first thing he does, the only thing he does is try to rescue his brother from his mindless torment.
- Evil Uncle: To Michael several generations removed, since one of the latter's ancestors was his brother. Specifically, he kills him, at least temporarily.
- FaceHeel Turn: initially he did want to stop William's rampages and rule peacefully, but Viktor's betrayal of him soured this side of his personality, although he did reign as an Elder for some time without attempting a coup until anyone in the coven who he felt respect or fear for died in Viktor and Lucian's war.
- Genetic Memory: He can see the memories of others by drinking their blood, something which Viktor could also do (and Selene as well, at least as of Awakening). Selene, Kraven and Andreas Tanis all become victims to his ability.
- Helicopter Blender: Selene pushes him into the spinning blades of a downed helicopter.
- Lineage Comes from the Father: All the members of the Corvinus family that we've seen (bar one) are male, and all the testing done in the first movie was on people whose surnames are derivatives of Corvinus.
- Monster Progenitor: He's the first true Vampire.
- Patricide: Kills his father, Alexander Corvinus, claiming that a God has no father.
- Sibling Team: Marcus and William.
- Super Strength: He could lift a massive stone door, and pull a helicopter out of the sky.
Alexander Corvinus's second son, and the first werewolf. Unlike Lycans, William could never regain his human form and was imprisoned by Viktor in a tomb, which was built by Selene's father.
- The Dragon: For Marcus after he's freed. He keeps Michael from helping Selene as she faces Marcus in the climax.
- Dumb Muscle: He's every bit as powerful as you would expect for the first Werewolf, but his mind is that of a feral animal dominated by instinct and savage bloodlust.
- Even Evil Has Loved Ones: Even in his feral, rage-fueled state, Marcus is the only person William will not attack or kill.
- Monster Progenitor: He's the first true Werewolf.
- The Nose Knows: After being separated for centuries, he recognizes Marcus by sniffing him.
- Off with His Head!: Michael wrenches William's jaw open to the breaking point, then rips his upper head off.
- Perpetual-Motion Monster: Once he's out of his coffin after over 600 years of imprisonment, he's at full strength. He clearly wasn't in suspended animation.
- Sealed Evil in a Can: Viktor would've preferred to kill him had he not agreed with Marcus to keep him alive.
- Sibling Team: With his brother Marcus after he's freed.
- Super Strength: Commonplace for werewolves, especially the very first. His blows send Michael flying and break stone.
- Tragic Monster: Despite all the carnage he's caused, William has no control over himself and is little more than a raging animal.
Where It All Began, Alexander Corvinus became the first true immortal after his village was ravaged by a plague which he was able to mold into what gave him his immortality. He then fathered three sons, Marcus, William and a third son. Marcus and William were bitten by a bat and a wolf, becoming the first vampire and werewolf, leading to the rest of the events in the films. The third son remained human, but carried the Corvinus Gene that would later lead to Lucian's quest to find a descendant who could adapt to vampire and Lycan blood.
- Almighty Janitor: He's been cleaning up the chaos the vampires and Lycans have been causing for centuries.
- Big Good: He has safeguarded mankind from the the Vampire-Lycan war and minimized the damage caused by it. In addition his blood gives Selene the necessary strength to defeat the Big Bad at the end.
- He also keeps the vampires and Lycans safe by hiding their existence from humanity. Once Alexander and his Cleaners die, humanity quickly initiates purges against both races, to devastating effects.
- Cleanup Crew: His men, all human, have been cleaning up after his children for centuries. Whenever possible without violence.
- Cool Boat: His roaming headquarters is a merchant vessel that's been thoroughly upgraded with all the latest tech. Also, awesome gothic decoration.
- Driven to Suicide: After giving Selene his blood so she can take down Marcus and William, he blows himself up with a bomb because he could not bear the pain of knowing he was about to lose his sons.
- Go Back to the Source: Selene and Michael visit Alexander, as does Marcus shortly after.
- The Older Immortal: The oldest character in the films.
- Passing the Torch: To Selene and Michael.
- Where It All Began: He became the first Immortal after surviving and being mutated by a mysterious virus. His immortality was passed down to his sons and the rest is history.
The daughter of Viktor, and Lucian's lover. The two were the original Star-Crossed Lovers, Sonja becoming impregnated with the first hybrid. Viktor was furious when he found out and had her executed via sunlight, kicking off the war. Lucian stole her necklace, actually one of the keys to William's tomb.
- Battle Couple: With Lucian, briefly.
- Childhood Friend Romance: Implied with Lucian.
- Cool Sword: She wields a rather nice sword that launches silver shuriken from the hilt.
- Cruel and Unusual Death: Poor Sonja. Chained to a column to await the risen sun. Not to mention her lover being beaten in front of her and forced to watch. And to top it all off, she's pregnant at the time as well.
- Dark Is Not Evil: Frequently wears black or dark colours, but is far from evil. In fact, she's one of the nicest characters in the franchise.
- Death by Origin Story: She's a posthumous character in the first film, killed by her father for the sin of miscegenation.
- Death by Childbirth: Her mother died giving birth to her.
- Death by Sex: Has sex with Lucian, gets pregnant with his child, is judged and sentenced to death for it.
- Defecting for Love: She helped free the Lycan slaves and was planning on leaving her coven to join them, because of her relationship with Lucian, though this never came to pass due to Viktor discovering what she'd done first.
- Doomed by Canon: Her death was the spark that ignited the Lycan-Vampire war, and was never retconned.
- Doppelgänger: She bears a remarkable, coincidental resemblance to Selene. Which is why Viktor turned Selene instead of just killing her.
- Eerie Pale-Skinned Brunette / Raven Hair, Ivory Skin: Being a vampire probably helps in this department.
- Famous Last Words: "Goodbye, my love."
- Imperiled in Pregnancy: For most of Rise of the Lycans.
- Interspecies Romance: With Lucian. Also doubles as an Interclass Romance, as she's the daughter of an Elder, while he's a slave.
- Lady of War: Usually dresses in a feminine manner (even her armour has a feminine touch, being form-fitting to her chest) and can outmatch her father in a sword fight. Also, as the daughter of Elder, she carries the title of 'Lady'.
- Lost Lenore: Is this to Lucian in the first film.
- Memento MacGuffin: Her pendant. Viktor gave it to her as a child, with her apparently viewing it as a mere token of his affections (according to the novelization, she was under the impression it had belonged to her late mother) unaware it's actually one of the keys to William's tomb. Lucian himself takes her pendant to remind himself of her after her death.
- Patricide: Averted. Whilst she does battle her father, she never tries to do him actual harm and outright states she has no desire to "defeat" him. In hindsight, it probably would've gone better for her if she had killed Viktor.
- Plot-Triggering Death: Her execution kickstarts the Lycanss centuries-long war with the vampires, and hence the entire plot of the franchise.
- Pregnant Badass: Though she doesn't reveal she's pregnant until quite late in Rise of the Lycans.
- Say My Name: Lucian screams her name in anguish when she's executed.
- Secret Relationship: With Lucian. It's implied they've kept it a secret for quite some time. Inevitably, it comes out eventually and Viktor is not happy.
- Star-Crossed Lovers: With Lucian. Anyone who's watched the original movie knows it ends tragically.
- Token Good Teammate: To the vampires in the prequel, being the only one who sympathises with the Lycans, views them as people and tries to help them.
- White Shirt of Death: When she's executed she's wearing a white shift.
Kraven of Leicester
Viktor's Dragon, Kraven is in charge of the old coven during Viktor's slumber. A Smug Snake and a Manipulative Bastard, Kraven helped fake Lucian's death to become a hero among the vampires, and to keep Lucian's plan under wraps. Their ultimate agreement is to eliminate the vampire elders, so Kraven can rule the vampires and Lucian can create the hybrid. Kraven has a thing for Selene, despite being perfectly willing to engage in casual sex with Erika.
- Blatant Lies: Everything that comes out of his mouth is a lie.
- Chronic Backstabbing Disorder: He does this to everyone (Viktor, Lucian, Erika).
- Dirty Coward: He shoots Lucian as his back is turned and pathetically grovels when Marcus, whom he intended to kill, has him cornered.
- The Dragon: To Viktor. Subverted, as he's planning on betraying him.
- Healing Factor: After getting stabbed in the leg, he's perfectly fine and able to run about a minute later.
- Jerkass: He demands respect he hasn't earned, treats Erika like crap despite her Undying Loyalty to him, just assumes Selene wants to be with him and tries to control her, even slapping her across the face at one point, shoots Michael purely out of jealousy, shoots Lucian for calling out what a loser he is and only looks out for Number One.
- Karmic Death: Kraven has his head blown off by Marcus whom he tried to kill seconds earlier.
- Large Ham: Kraven's reaction to Erika telling him that Michael is a Lycan is downright hilarious.
- Meaningful Name: The word "craven" means "coward".
- Non-Action Guy: Despite being a Death Dealer, he generally lets everyone else do his dirty work. The only time he actually lifts a weapon is to shoot Lucian and Michael in the back. However it is implied that he was something of a competent warrior in his youth.
- Obviously Evil: The guy is a scowling aristocrat who ignores Selene's suggestions and requests while creepily pining after her.
- Opportunistic Bastard: Kraven has no loyalty to anyone or anything but his own ambition. When spared from death by his own cowardice at the hands of the Lycans' leader Lucian, Kraven aligns himself with Lucian's plans to seize power for himself in the vampire covens. Kraven seizes on a chance to allow Lucian's Lycans to massacre the vampire elder Amelia, and when his treachery is exposed, he later betrays and murders Lucian before taking advantage of the resulting power vacuum from the large scale battle at the conclusion of the second film to attempt to murder the final sleeping vampire elder and rule the coven. Lacking his own plans, Kraven simply ingratiates himself to whoever is in power for his own success and has no compunction taking any chance fate gives him in pursuit of it.
- Sissy Villain: Selene, Lucian, and damn near everybody thinks he's a little bitch. He even kills Lucian for calling him out on it.
- Stalker with a Crush: He's quite obsessive over Selene.
- The Starscream: To everybody. He teamed up with Lucian to defeat the vampire elders, and then turned on Lucian. He's eventually Rewarded as a Traitor Deserves by the last elder Marcus, who caught on to this act.
- Sudden Sequel Death Syndrome: Especially considering most fans were expecting him to be the villain opposite a heroic Marcus.
- What Does She See in Him?: Its easy to wonder this when considering Erikas desire for him, although the fact that according to the novel he was her sire is probably part of it.
Lucian's closest friend and a Scary Black Man. He became a Lycan in Rise of the Lycans and helped Lucian fight back against their vampire suppressors. He has a rivalry with vampire Soren going back to their earliest days. And yes, his voice is actually that deep.
- Badass Baritone: Raze's deep voice is actually that deep.
- Badass Normal: Back when still human. First thing he does when confronted with one of the wild and feral Werewolves? Punches the damn thing down. Three vampires struggled to restrain him.
- Black Dude Dies First: Averted. He dies about the same time as Kahn, which is in the final act of Underworld and outlives every other named Lycan except for Lucian (who wasn't that far behind him).
- Creator Cameo: Raze is played by Kevin Grevioux, writer for the films.
- The Dragon: To Lucian. Also The Big Guy.
- Dragon Their Feet: Lucian is betrayed and fatally wounded by Kraven not long before Raze arrives with the elder blood.
- Roaring Rampage of Revenge: After returning to the lair only to find Kraven dead, he mourns his friend's passing, composes himself, and hurls himself at the vampire invaders.
- Scary Black Man: Due to his size.
- Undying Loyalty: To Lucian.
Kahn is the weapon's specialist in the coven and head of security. He clashes with Kraven, and is just as suspicious of him as Selene is. He is a skilled marksman and inventor, replicating the Lycans' sunlight weapon with silver bullets which can harm Lycans on the genetic level.
- Black Dude Dies First: Averted. He is the last main vampire character to be killed before Viktor.
- And considering that the camera cuts away right as his group is ambushed and never goes back to them, it might be a case of Uncertain Doom instead.
- Genre Savvy: Begins to realize Selene may be right about Kraven after Kraven doesn't send his team, but a less trustworthy group led by Soren, to pick up Amelia and the council from the train station, and shortly afterward sends one of his men to investigate.
- Nice Guy: He's one of the nicest vampires in the series.
- Techno Wizard: Responsible for creating silver-nitrate bullets, which he achieved by copying the Lycans' UV ammo.
Kraven's one-and-off girlfriend, Erika is pretty much used by Kraven for sex, and he treats her like dirt whilst pining after Selene. Erika discovers that Michael is a Lycan and tells both Selene and Kraven. After finding out that Kraven intends to make Selene his queen, Erika ditches him and frees Selene from her imprisonment to get back at Kraven. Her fate afterwards is unknown. In the novelization, she and Selene have a somewhat tenuous friendship, and it's mentioned that she left the mansion and "wondered if Viktor liked blondes."
- Clingy Jealous Girl: She gives this up eventually.
- Cute Little Fangs: While clinging to the ceiling. And hissing like a deranged cat.
- Friendly Neighborhood Vampire: Poses no threat to humans, and is sociable with her fellow vampires.
- Friend Versus Lover: With Selene, who is her friend and an object of Kraven's obsession (although Selene doesn't want to be).
- Evil Brit: averted, although she does appear to have some of the Fantastic Racism towards Lycans.
- Non Action Girl: She is uninvolved in the covens fighting and is aware of it, showing a healthy respect for Death Dealers like Selena and Khan.
- Oh, Crap!: seems both frightened and reverent when she sees Viktor woken up and quickly kneels before him.
- Sideboob: In one scene.
- Screw This, I'm Outta Here!: one interpretation of what she does after Kraven leaves her behind when he flees.
- Toplessness from the Back: In the same scene.
- What Happened to the Mouse?: Erika only appears in Evolution during a flashback, and it is never established whether she was among Marcus's victims when he destroys the coven, leaving her ultimate fate in the franchise unknown.
- Woman Scorned: Eventually turns on Kraven after one too many betrayals.
- Wrong Genre Savvy: Spends most of the movie seemingly believing that she is the female lead of a much lighter Gender Flipped Uptown Girl story with Kraven and that sooner or later he'll realize Selene isn't interested in him and give her the time of day. She seems to give up on this after Kraven flees the mansion.
A scientist Lycan, Singe has spent years trying to find the right carrier of the Corvinus strand, and is at his wit's end. Lucian delivers him Michael's blood and he is proven a carrier. Singe is sent to help retrieve Michael from the vampires but is captured by Selene and forced to reveal Lucian's plan and Kraven's treachery. After Amelia is killed, Viktor punches him to death.
- Chekhov's Gun:
- His blood turns Marcus into a hybrid.
- Selene recalls Singe mentioning the hybrid's creation and follows his advice to turn Michael into a hybrid.
- Do Not Taunt Cthulhu: Learns this the hard way with his smugness towards Viktor, although it could also counts as being Defiant to the End given the unlikelihood he would have had of walking out of their anyway.
- Megaton Punch: Viktor delivers one that kills Singe instantly.
- Omnidisciplinary Scientist: Singe is a skilled scientist in biology, genetics and medicine, not to mention espionage.
- Reluctant Mad Scientist: He's a bit tired of doing his experiments, but still is a mad scientist by chaining Corven family members up.
Kraven's minion and once Viktor's bodyguard. Little is known about him, but he has a rivalry with Raze. He uses a pair of whips in battle, and is killed by Raze.
- Enigmatic Minion: Is apparently content to remain Kraven's second, with no explanation for this, despite being almost as old as Viktor, and having had various positions of authority in the coven.
- Evil Minion: Under Kraven.
- The Rival: To Raze.
- Kahn also seems to slightly dislike him, and how he is granted more important jobs by Kraven.
- Sinister Shades: Wears a pair, with it being most notable as they reflect the gunfire when Amelia and her entourage are under attack.
- Whip It Good: Enhanced by combining it with a dose of Dual Wielding. Of note, his whips appeared to be silver and razored.
Introduced in Underworld: Evolution
Formerly the historian of the vampire coven, Andreas Tanis was exiled on Viktor's orders, by Selene, for telling "malicious lies".
- Everyone Has Standards: He refused to falsify history for Viktor, and also seemed unsettled by Sonja and Lucian's trial.
- The Exile: To a remote church that he's fixed up into a sybaritic love nest.
- Imperial Stormtrooper Marksmanship Academy: While Selene is distracted, he tries to shoot her in the back from about 15 feet away and misses. She snarks that his aim hasn't improved since she last saw him.
- Mr. Exposition: Well, he is the vampire historian.
- Oh, Crap!: When Marcus comes for him. He completely freaks out despite the latter's affable demeanor, and given what Marcus does to him, it's not unwarranted.
- Pet the Dog: While he only covered up Lucian and Sonja's relationship in the first place in exchange for a bribe (her council seat), even after receiving it, he snuck Sonja into the prison to visit Lucian after his arrest.
- Secret Keeper: A somewhat self-interested one.
- The Smart Guy: Only one besides Marcus and Viktor to know the true history and designed the weapons that the Lycans unleashed in the first movie.
- Techno Wizard: Built weapons for Lucian after he was exiled.
- Wild Card: In the third movie, while mostly an ally of Sonja and Lucian, he does stand by during their trial (although it is unlikely he could have done anything with either words or actions that would have made a difference) and also rescues the elders and their caskets when the Lycans storm the castle.
Olga and Grushenka
- Black Bra and Panties: Grushenka, during her screen time.
- Combat Stilettos: Their wearing platform heels while they fight Selene.
- Full-Frontal Assault: Olga fights Selene wearing just a partially opened robe.
- Named by the Adaptation: The film only credits them as Tanis Vamp #1 and Tanis Vamp #2, while they get names in the novel.
- A Threesome Is Hot: The two are introduced having a threesome with Tanis.
- Violently Protective Girlfriend: Both move quickly to defend Tanis against the feared Death Dealer Selene, although neither does well.
- The Voiceless: Neither have any dialogue.
- What Happened to the Mouse?: Selene slams their heads against the stone wall hard enough to break pieces of the wall off, but these aren't injuries which are typically fatal for a vampire. Afterwards Tanis is seen carrying them out in the cellar in a way which could be interpreted as either laying them out to recover or taking out their bodies before he hears Marcus coming, and if they were just unconscious it's unclear what would have happened when they woke up and found Tanis dead.
- And Then John Was a Zombie: He's turned into a werewolf during the final assault against the Corvinus brothers.
- Badass Normal: He's an ordinary, mortal human unafraid to fight against heavily armed monsters.
- Bearer of Bad News: He's the one to report that Marcus has woken up and burned down The Elders mansion.
- Disposing of a Body: He's apparently a veteran in doing this to uphold The Masquerade.
- Icy Blue Eyes: He's a grim, blue-eyed man.
- Number Two: He seems to be Alexander's second in command and has authority over his men in the field.
- Undying Loyalty: He's loyal to Alexander and upon seeing him hurt is distressed and races to help him.
Introduced in Underworld: Rise of the Lycans
- Bearer of Bad News: She's the one to tell Lucian of Sonja's arrest.
- Heroic Seductress: She is used by Sonja to lure away the guards to the Lycans dungeon at one point with the promise of sex while Sonja goes to see Lucian.
- Hidden Depths: Offers some comforting words to Sonja as Lucian is whipped.
- The Quiet One: Speaks less than sixty words of dialogue in any version of the story and in the final version of the film speaks less than twenty.
- Secret Keeper: Serves as one for Lucian and Sonja (something that gets more detail in the novel and comic)
- Undying Loyalty: to Sonja, although she seems to disapprove of her relationship with Lucian — which might make her Properly Paranoid given how it turned out — she never betrays them.
- What Happened to the Mouse?: The movie novelization has her caught in the crossfire along with the rest of the vampires when the Lycans attack the castle but in the movie and graphic novel it's questionable if she was even there at the time, after they'd executed her mistress and she'd left the castle to tell Lucian of their intentions.
- What You Are in the Dark: Despite apparently not appearing to like Lucian much, she goes to warn him about Sonja's arrest and Viktor's knowledge of their affair when it would have been easy to do nothing. Whether she does this to give Lucian a warning to keep him safer, or out of hope that he can rescue Sonja is unclear, but either way she would have likely been killed by the coven if they'd found out what she was doing.
- You Should Have Died Instead: Seems to show a little bit of this when telling Lucian about Sonja's impending fate.
- Bait the Dog: While somewhat pragmatic, he is less harsh towards the Lycans and the humans than Viktor, but in the end, it isn' enough to keep him from referring to their slaves freedom as a "disease" and insulting Sonja for consorting with Lycans during her trial and calling for a vote to have her executed.
- Commander Contrarian: often opposed to Viktor, feeling frustrated with his lack of concern with protecting their humans subjects, and the potential consequences that will bring, as well as Viktor's frequent dismissal of any suggestions he makes for those subjects.
- Fantastic Racism: he's also alarmed at the idea of a hybrid and concedes that Sonja cannot be allowed to give birth to one, although he displays more tolerance towards Lycans in general than Viktor.
- Gory Discretion Shot: Coloman isn't explicitly shown being killed, but he is surrounded and jumped on by the Lycans (along with several other councilors) and his Non-Action Guy status makes it unlikely he could have defeated them.
- Honest Advisor: Cones across as this, although Viktor doesnt appreciate it and suspects his motives according to the novel.
- Motivation on a Stick: Is a firm believer in this, noting that they aren't given the humans good reason to keep producing silver, due to being spread too thin to protect them, and that neither have they given the Lycan slaves reason to help them, in their present state.
- Mouth of Sauron: an ally of Marcus, according to the novel, whose interests he protects while Marcus is slumbering.
- Non-Action Guy: spends his time focusing on the covens politics and is irritated at Sonja's decision to go out hunting werewolves rather than do the same. When the Lycans attack at the end, he can do nothing but run and cower.
- Pet the Dog: Suggests promoting Lucian to a role of overseer, and giving some of the Lycan slaves more freedom and better treatment in exchange for getting them to protect the humans against the feral werewolves during the day.
- Ungrateful Bastard: Invoked when Sonja accuses him and the other councilors of ignoring all the times she's saved the coven during her trial and Coloman counters that nonetheless she has provided aid to its enemies and killed fellow vampires.
Sabas and Xristo
- Fantastic Racism: showing that this can go both ways, they're reluctant to trust the aid provided by vampire Sonja, although given what they've been through, it's not too unreasonable.
- Pet the Dog: Help treat Lucian's wounds after he's whipped.
- Those Two Guys: They share all of their scenes and seem to be confidants to each other.
- Took a Level in Badass: Both of them, when it comes form serving the vampires to fighting them.
- What Happened to the Mouse?: Both survive the movie but their fate in the centuries of war that follow are unknown.
Introduced in Underworld: Awakening
Eve (Subject 2)
A young Hybrid Monster who Selene finds after awakening 12 years after the purge of vampires and Lycans.
- Creepy Child: When in her hybrid form. Not only is she a dead ringer for Regan McNeil, but the first kill she performs involves ripping a Lycan's skull in two. Like father, like daughter.
- Genetic Memory: Can see through the eyes of her parents, and they can do the same in return.
- Hybrid Monster: And one who is potentially even more powerful than her father, considering that not only is she the daughter of a hybrid, her mother just so happens to be a vampire who possesses immortal genes.
- I Hate You, Vampire Mom: Resents her mother, Selene's, apparent detachment towards her until Selene explains it's due to her being broken hearted over Michael's disapearance. While the two do bond over Awakening, Selene later has to send her away so she would not be in danger from the Lycans.
- Ill Girl: She spent her whole life in a lab and has never drank blood before.
- Living MacGuffin: In Awakening, the Lycans plan to extract her genetic code to make Lycan clones. In Blood Wars, they're still after her, albeit for seemingly slightly different reasons.
- Luke, You Are My Father: Casually reveals that she's Selene's daughter while on escape from the facility.
- Put on a Bus: After Awakening, Selene sends her away (or she goes away herself) to protect her from being hunted by the Lycans. That said, her absence is noted multiple times throughout Blood Wars; in fact, one of the Lycans' goals is to extract information from Selene about Eve's whereabouts. She makes a cameo appearance at the end of Blood Wars, though with a body double.
- The Runaway: At some point between Awakening and Blood Wars, Eve runs off for parts unknown, leaving Selene a lock of her hair and a note stating in no unclear terms that her mother is not to try to find her. They reunite in the end.
- Unskilled, but Strong: Can rip a transformed Lycan apart with her bare hands but obviously has never been in a real fight. Like father, like daughter.
Introduced in Awakening, David is a survivor of the Purge. The Idealist of the film, David aids Selene, willingly helping her and Eve escape the humans and Lycans. He believes the vampires should honor their predecessors and fight back, being at odds with his father Thomas.
- Ancestral Weapon: In Blood Wars, he gains a silver sword that Thomas had forged.
- Awesome Moment of Crowning: At the end of Blood Wars, he is designated a part of the new Elder Triumvirate, the vampire equivalent of royalty.
- Back from the Dead: Killed by Lycans, but is resurrected by Selene when she cuts open her palm and then forcefully using her hand and immortal blood to restart his heart.
- Big Damn Heroes: Arrives in the climax of Awakening just in time to help Eve dispatch Lane.
- Daywalking Vampire: After being revived by Selene in Awakening he has become an Hybrid.
- I Hate You, Vampire Dad: He is at odds with his father Thomas, the local Well-Intentioned Extremist, who wishes to hide away to survive instead of fighting back.
- The Idealist: Dreams of restoring the Vampires to their former glory and looks up to Selene as the one who will help achieve this.
- The Lancer: To Selene since Michael is unavailable. Shared with Detective Sebastian.
- Missing Mom: His mother apparently died giving birth to him. It's then revealed his mother was actually the Vampire Elder Amelia, who was forced to leave him for his own protection.
- Rightful King Returns: Blood Wars reveals that he is the son of Amelia, making him not only the last surviving Elder heir of the Eastern Coven but also the supreme head of the vampire council. He announces his claim before the climax and is formally designated at the end.
- Royal Blood: Thanks to being Amelia's son.
- Suspiciously Similar Substitute: To Kraven just without any Jerkass tendencies and like Michael, serves as a possible Love Interest to Selene and comes back from the dead. With the latter being more possible since Michael was Killed Off for Real in Blood Wars.
David's father and ersatz Elder of the surviving Western Coven vampires following the deaths of Amelia, Viktor, and Marcus. Unlike his son, he feels that continuing to fight will only hasten the demise of their species and favors hiding out until things blow over. Roughly 20 years before the events of Underworld, he became the lover of the vampire Elder, Amelia, resulting in David's birth, but was forced to break off the relationship and go into hiding for David's safety.
- Expy: If Thomas were a lot meaner and/or ruthless, he'd be Viktor 2.0; he's got the looks and general mannerisms down to par. He also takes on the role of an acting Elder in Awakenings.
- Cool Old Guy: In Blood Wars, he has mellowed out somewhat, is more open to David's way of thinking, and become a lot fonder of Selene due to her saving David's life in the previous film, even personally going against the Council to offer her amnesty within the Coven. Oh, and he's shown to be a badass with a sword.
- Foil: To Viktor of all vampires. Despite being an Expy of the deceased Elder, Thomas is more reasonable by comparison and genuinely acts for the good of the vampires in his charge, his son included, rather than his own interests. Also, he would rather lay low when then odds become overwhelming while Viktor never backed down from a fight.
- Heroic Sacrifice: He goes up against Semira and Varga while trying to buy David time to escape with a comotose Selene and is tragically stabbed to death for his efforts.
- I Did What I Had to Do: Thomas's defense for handing Eve over to the Lycans is that he did so in order to avoid the further slaughter of his coven.
- Pacifist: Would rather for the vampires to hide and lay low as opposed to fighting the Lycans and the humans trying to seek out and destroy them.
- Sword Cane: He dual wields his sword and the cane he draws it from.
- Well-Intentioned Extremist: He does all he can to keep what's left of the Western Coven safe, including handing over an innocent 12 year old Ill Girl to the people seeking her whilst knowing that doing so will be a death warrant for said girl.
The first human since Michael to become a prominent character in the films. A police detective who pities the vampires and Lycans, Sebastian teams up with Selene to take down Antigen to save Eve and avenge his dead vampire wife.
- Badass Normal: He's well versed in fighting Lycans and presumably vampires as well.
- Black Dude Dies First: Oh so averted. In fact, not only does he not die, he gets props for being the first and only non-infected human character to do so in this series.
- The Lancer: To Selene, shared with David.
- Made of Iron: He suffers a No-Holds-Barred Beatdown from Jacob Lane, which ends with Jacob slamming his head into the concrete, and he remains conscious and defiant.
- One-Man Army: Single-handily launches a one-man assault against Antigen, kills a guard with a rocket launcher, helps stop a van carrying off Eve, tries to fight the Big Bad, and survives with the intention to cover Selene.
- Suicide by Sunlight: His wife, a vampire, willingly walked out into daylight and killed herself so he would not have to see her be murdered during the Purge.
- Super Cop: Of the Badass Normal type. He is like John Matrix of Underworld.
Doctor Jacob Lane
Chief scientist at Antigen, Jacob Lane kept Selene, Michael and Eve as test subjects to find an antidote to the vampire and Lycan viruses.
- Big Bad: Of Awakening.
- Healing Factor: Heals almost instantly from Sebastian and David's gunshots. However, it's not powerful enough to save him from a ripped out throat.
- "It" Is Dehumanizing: Constantly calls Eve "It" or "Subject 2", and even kills one of his employees for caring too much about the girl.
- Mad Scientist: He is a Lycan scientist who wishes to make his species completely invulnerable.
- No-Sell: He's immune to silver due to injecting himself with Eve's blood.
- Slashed Throat: Eve tears his throat out.
- Well-Intentioned Extremist: He comes off as one, wanting to protect humanity from Lycans and vampires. Turns out he's a Lycan, and what he wants is to wipe out vampires and have Lycans become dominant.
A wolf known as the Uber Lycan, Quint kidnaps Eve so Dr. Jacob Lane can use her to create an army of Lycans.
- Canis Major: A huge Lycan, over twice as tall as a regular one.
- The Dragon: To Dr. Lane.
- Even Bad Men Love Their Mamas: He comments that he wishes his mother was still around. Jacob dismissively says she abandoned them by choosing not to become a Lycan.
- Healing Factor: A pretty powerful one. His wounds heal almost instantly. Selen uses this against him by shoving a grenade into his body and his wounds heal too quick for him to dig it out.
- Hoist by His Own Petard: Doomed by his own Healing Factor.
- Insert Grenade Here: Selene shoves a grenade into Quint's body just as he heals his wounds.
- Ludicrous Gibs: His fate when a grenade explodes while inside him.
- No-Sell: He's immune to silver due to injecting himself with Eve's blood.
- Oh, Crap!: When Selene reveals she stuck a grenade inside him, he screams in horror and desperately claws at his own torso before blowing up.
- Painful Transformation: A side-effect of the treatments that made him so large seems to be that he can't transform seamlessly like most Lycans.
- Partial Transformation: He can turn just his hand into a paw.
- Slasher Smile: Quint does this in his Uber-Lycan form... twice.
- Super Strength: In human form, he can Neck Lift and Neck Snap people and break an elevator cable. In wolf form, he can throw cars around.
- Why Am I Ticking?: He's largely immune to silver due to being injected with Eve's blood, and has a powerful Healing Factor making him nigh invulnerable to injury. Selene takes him out by jamming a grenade into his body just as his wounds heal; when the bomb goes off, the sheer force of the explosion from within rips him apart, and leaves behind a smoking pile of Ludicrous Gibs.
Introduced in Underworld: Blood Wars
One of the leaders of the Eastern Coven, who plots to take over the coven and make herself a Hybrid.
- Absolute Cleavage: Most of her outfits emphasise this.
- Bad Boss: To Varga. It eventually come back to bite her in the ass.
- Battle Couple: With Varga when they fight Thomas.
- Beauty Is Never Tarnished: Oh, so averted. Being stabbed in the mouth from the back is not a pretty way for her to go.
- Big Bad Ensemble: Along with Marius.
- Brainy Brunette: Dark-haired and very cunning and manipulative.
- Dark Action Girl: She's the first prominent female villain in the series and a skilled swordswoman.
- Daywalking Vampire: She becomes immune to sunlight after drinking Selene's blood.
- Depraved Bisexual: She attempts to seduce David and also plants a kiss on Alexia's lips just before killing her.
- Famous Last Words: "It worked!"
- Green-Eyed Monster: Her hatred of Selene is implied to have been partly caused by her jealousy over Selene becoming Viktor's new favourite.
- Hypocrite: She kills Alexia for her betrayal against their kind, (which ultimately does lead to many vampires being slaughtered) but has no qualms about ordering the death of at least two dozen unsuspecting Death Dealers-in-training, or murdering Thomas and attempting to do the same to David, to further her own ends.
- It's All About Me: After drinking Selene's blood, she smashes the bowl to the ground instead of sharing it with her lover Varga, who was in the room with her.
- Karmic Death: Her fascination at successfully hybridizing herself distracts her long enough for David to blindside her with a sword through the back of the head after she killed his father, Thomas, in the same manner. Said sword was originally owned by Thomas.
- Lady of War: A coven leader and a skilled warrior, who usually wears rather elegant and feminine outfits.
- Manipulative Bitch: Most clearly demonstrated during the Council meeting, where she feigns nothing but concern for the coven and acts like it was all Thomas's idea to bring Selene in.
- Ms. Fanservice: She uses many gorgeous dresses, some sporting Absolute Cleavage and indicating that there is also nothing underneath it. Being The Vamp (figuratively speaking) and played by the gorgeous Lara Pulver doesn't hurt either.
- Nice Job Fixing It, Villain!: Her poor treatment of Varga leads him to betray her to help the protagonists, whilst her earlier attempt to kill Selene and David forces them to seek out the Nordic Coven for protection allowing David to learn of his true heritage as Amelia's son and heir, and return with proof to challenge her for control of the covens.
- Opportunistic Bastard: She's essentially a female version of Kraven, though more competent.
- Pay Evil unto Evil: She kills Alexia for her betrayal while trying to wrest control of the Coven for herself via subterfuge and hybridizing herself.
- The Vamp: She uses her beauty and sexuality to get what she wants (or tries to, at any rate).
- Villain Has a Point: Whilst she's primarily motivated by her own ambition, Semira's got a pretty good point about the Council doing nothing about Marius being a huge mistake.
- Villainesses Want Heroes: A downplayed example. She clearly shows an interest in David, though he makes it pretty clear the feeling isn't mutual. The moment he interferes with her plans, she has no qualms about trying to kill him.
The Lycans' new leader in Blood Wars and one of the deadliest Lycans since Lucian, who seeks to use Eve's blood to increase his power.
- Bad Boss: The guy at one point uses one of his comrades as a human (or rather, Lycan) shield. Since he's immune to silver bullets anyway, he got that man killed needlessly. On the other hand, most of his troops seem to look up to and respect him, he gives them encouragement and he lets another Mook live despite repeated failures, though he does smack him about a bit.
- Beast with a Human Face: His powered up Lycan form has a more human appearance than regular Lycans while still looking more beastly than Michael's hybrid form.
- Big Bad Ensemble: Alongside Semira.
- Domestic Abuser: Downplayed. In one scene, he grabs his girlfriend by the throat and slams her against a wall, though he's not shown mistreating her otherwise.
- Even Evil Has Loved Ones: He seems to genuinely care for his lover Alexia.
- Foil: To Lucian and Michael. They're all Lycans who take vampire lovers, but he's the only one who is truly villainous whereas Lucian only wanted freedom for his species and Michael simply wished to be left in peace. Also, Lucian actively pursues vengeance for Sonja's death whereas Marius is seeking revenge for Alexia, but doesn't openly state it.
- Forgotten Fallen Friend: He shows no visible reaction to Alexa's death and it's implied she was just his way of keeping tabs on the Coven.
- Genius Bruiser: The man is very tall and imposing, but he is no mere brute just because he is a Lycan: a genius tactically speaking, having turned the Lycans into an effective fighting force by utilizing tools that make them more versatile.
- Healing Factor: He heals from getting shot, impaled with a sword, and slashed across the throat in seconds.
- Kick the Dog: After Selene discovers he killed Michael, he shows her vial containing Michael's blood and says that it's "all that's left of him", whilst holding it out to her. As Selene reaches for it, he promptly tips the contents of the vial down his throat to boost his power.
- Interspecies Romance: With The Mole, Alexia.
- No-Sell: He's immune to silver due to drinking and injecting himself with Michael's blood.
- And Show It to You: Selene kills him by ripping his entire spinal column out.
- Super Strength: He effortlessly manhandles Selene and throws her through a castle wall. Later, he kills a Nordic Vampire by punching a hole right through his armored torso and tears a cage apart.
- Villainous Breakdown: After acting cordial with Selene even when fighting her, when Alexia drinks her blood to see her memories and confirms Selene doesn't know where Eve is, he loses his temper and shoots Selene several times while screaming.
- Would Hurt a Child: He seeks to use Eve's blood to make himself more powerful. Played with in that he does tell Selene he won't actually kill Eve, though it's unclear if he's being honest and Selene certainly doesn't believe him.
The lead Death Dealer of the Eastern Coven and ally to Semira.
- The Dragon: To Semira. He jumps ship the moment he learns David is the rightful heir to coven, due in no small part to Semira's crappy treatment of him.
- Dumb Muscle: Averted. He's actually not that stupid and Semira treating him like he is proves to be a big mistake on her part.
- Foil: To Kraven. They're both pretty boy types directly serving higher vampires but while Kraven openly plots to do away with Viktor and take control of the coven, Varga is loyal to the coven and more specifically, to its rightful ruler; when this is revealed to be David, he promptly turns against Semira but it wasn't premeditated.
- HeelFace Turn: After learning that David is the rightful heir to coven, he turns on Semira and devotes himself to David.
- Karma Houdini: He gets no comeuppance of any kind for being party to the attempted murder of Selene and killing several Death Dealer trainees and framing Selene for it. Even though he was Just Following Orders, it's still rather glaring.
- Poisoned Weapons: He has a dagger laced with nightshade, which kills lesser vampires and paralyzes stronger ones.
- Sir Not-Appearing-in-This-Trailer: He has a pretty large role in the film, but is barely featured in trailers and promotions.
A Death Dealer in the Eastern Coven, who is secretly Marius' lover and spy.
- Anti-Villain / Villain Has a Point: In spite of some of her more morally questionable actions, Alexia doesn't really seem to be truly evil, lacking the Jerkass tendencies present in most of the other villains. It's implied part of her motivation is wanting to stop the war and take out Semira, who she rightly fears only cares for her own ambition. She seems pretty emotional at times, often tearing up, and during her confrontation with Selene, she's practically begging her to help them and doesn't seem all that enthusiastic about killing her.
- Foil: To Selene (and by extension, to Sonja). They're all Death Dealers or high-ranking vampires who fall in love with Lycans and ultimately betray their covens. However, whilst Selene only turned on Viktor after he betrayed her first and flees with Michael and Sonja only fought her fellow vampires to protect Lucian and her unborn child, Alexia actively helps the Lycans to invade the coven and doesn't seem to care that her former comrades are probably going to be slaughtered, making her far less sympathetic. Sure enough, she gets Rewarded as a Traitor Deserves.
- Forgotten Fallen Friend: If Marius feels any grief or anger about her death at Semira's hands, he doesn't show it.
- Interspecies Romance: With Marius to an extent, seeing as Lycans and vampires are viewed as separate species, but are technically humans infected by different strains of a virus.
- In the Back: Stabs Selene through the back with a sword.
- The Mole: Serves as one for Marius.
- Rewarded as a Traitor Deserves/You Have Outlived Your Usefulness: Semira, as it turns out, knew about Alexia's betrayal all along, taking her out with a Slashed Throat once she's fulfilled her purpose.
- The Starscream: To Semira. Goes about as well for her as it does for the Trope Namer.
One of the leaders of the Eastern Coven, who greatly despises Selene for killing Viktor.
- Kneel Before Frodo: He's the first to bow to Selene, David, and Lena when they become the new elders.
- The Nose Knows: He recognizes the scent of Amelia's blood even after she's been dead for over twelve years.
- Reasonable Authority Figure: Despite his hatred of Selene, when she is framed for killing several Death Dealers, he orders her to be brought in alive so she can stand trial. When David proves he is Amelia's heir, he immediately defers to him.
- Super Strength: He manages to wrestle a transformed Lycan to the ground and pin it before shooting it in the head.
- Tempting Fate: He boasts that the Eastern Coven's fortress is impregnable, shortly before Marius' army invades it.
A member of the Nordic Coven, with special abilities granted by a 'cocooning' process known only to her people.
- Action Girl: Despite not being a Death Dealer like Selene and appearing vulnerable, she is a vampire and isn't afraid to take up a sword and going against her enemies.
- Awesome Moment of Crowning: Is made a part of the Elder Triumvirate at the end of Blood Wars, the only non-Eastern Coven vampire to be so.
- Daywalking Vampire: Develops this property by being given the blood of Selene, who herself had taken up the blood of Alexander Corvinus, The Older Immortal.
- The Empath: She says she can read people's souls. It may be closer to telepathy, as she is able to recite several details from Selene's life.
- Enigmatic Empowering Entity: Played with. She teaches Selene the cocooning process used by her coven, which grants her extra powers to defeat Marius, the Lycan half of the Big Bad Ensemble and she comes across as quite mysterious, though this is more due to the fact her character as only just been introduced. Selene herself gives Lena her blood, thus turning her into a Hybrid, in return for her help.
- Exposed to the Elements: When introduced, she's barefoot and in a backless dress in snowy conditions.
- Flash Step: Part of her status as a Nordic Coven vampire.
- Helmets Are Hardly Heroic: During the climax, the Nordic coven serves as The Cavalry against the Lycans and they are all wearing heavy armor to protect them from the sunlight — except for Lena. This is used to illustrate that she has become an immortal hybrid just like Selene.
- Hidden Elf Village: The Nordic Coven remains hidden somewhere in Norway or Sweden and has refused to take part in the Vampire-Lycan War. Appropriately enough, Lena and her people have some vaguely elvish appearance.
- Ms. Fanservice: When the Lycans attack her coven, she doesn't bother suiting up from the skimpy tunic/loincloth she's wearing; she just grabs a sword and shield and starts killing them.
- Meaningful Name: Lena is the Scandinavian diminutive of Elena or Helen, which means "bright" or "shining".
- Mystical White Hair: Implied to be the result on having gone through the cocooning process many times.
- Nice Girl: Easily one of the nicest characters in the series. Unless, of course, you're threatening her coven...
- Sexy Scandinavian: Lena is a gorgeous Nordic vampire lady with silver-hair.
- White Shirt of Death: Her white clothing is eventually covered with enemy blood.
The leader of the Nordic Coven and Lena's father. He was a close friend to David's father Thomas and the Elder Amelia.
- Bald of Awesome: Notably, he is the only bald vampire among his coven, where everyone else was blonde or silver-haired.
- Cool Old Guy: Vidar is welcoming and pleasant towards Selene and David, which is refreshing for other vampires in the series.
- Meaningful Name: He shares the same name as the Norse God of Agriculture, who killed the wolf Fenrir in revenge for devouring his father, Odin.
- Secret Keeper: Vidar reveals to David that his mother wasn't a lowborn that died in childbirth as his father told him, but Amelia herself.
- So Proud of You: When David takes up his father's sword, he pats him on the back with a giant grin on his face.
