The central character, summoned to Earth by Grigori Rasputin and a group of Nazi occultists in the final months of World War II as part of Project Ragna Rok. Found by the U.S. Army, he was raised by Professor Trevor Bruttenholm in an Air Force base in New Mexico. In adulthood, he became the primary agent for the BPRD, until he left in 2001 to find his destiny.
- The Alcoholic: He realises in "The Storm And The Fury" that he's been drinking solidly for six years and has made a lot of bad decisions, so he quits.
- An Arm and a Leg: He was born with a normal right arm, but shortly after his birth, his father cut his right arm off and replaced it with Anum's.
- An Axe to Grind: During his battle against the Queen of Blood's forces, he makes liberal use of a battleaxe he takes from one the fae.
- The Antichrist: Though he's not too keen on the idea and becomes an Anti Anti Christ which ultimately costs him his life.
- Anti Anti Christ: He's the poster child for it. The only demon that doesn't want Hellboy to bring about The End of the World as We Know It is Hellboy himself.
- Apologetic Attacker: In the first volume, he apologizes to the frog monster that was once Sven Olafson as he shoves a grenade down its throat.
- Art Evolution: He started off pretty boxy and beefy, along with his hair being in what appears to be a buzzcut. As the series went on, Hellboy became more and more thin, with his shoulders progressively narrowing and the Right Hand of Doom larger than it was initially.
- Artifact of Doom: Anum's Right Hand of Doom, the key that will release the Ogdru Jahad and bring about the Apocalypse.
- Ascended Demon: He's so heroic that his spilled blood causes lilies to sprout.
- Back from the Dead: Seven years after Nimue tore his heart out and banished him to hell, and with the help of Sir Edward Grey and the soul of Roger, Hellboy returned to the world of the living (In Roger's coffin, no less) at the end of The Devil You Know: Messiah
- Big Eater: Eats more than you'd expect even from someone his size.
- Big Red Devil: His general appearance, though he tries to downplay it by filing his horns down.
- BFG: The Good Samaritan in the films, and its inspiration, the Hand Cannon given to him by the Torch of Liberty when he was younger. He eventually loses this at the bottom of the sea, and replaces it with a Colt 1911, which he loses fighting giants a year or two later. Beyond these he has a tendency to lose any firearms he's given. It doesn't bother him, because he's actually a rather lousy shot by his own admission:"I'm a lousy shot...but the Samaritan here fires really big bullets."
- Characterization Marches On: Under John Byrne's pen, Hellboy is a lot more hotheaded and prone to attacking first without provocation (which is likely where the Del Toro film version of the character got his personality from). After Mignola took writing the series into his own hands, Hellboy very quickly settled into his unflappable Deadpan Snarker self, and his moments of anger (besides his Berserk Button at the mere sight of Nazis) are shown to be entirely justified and due to the attackers starting the fight.Bryne!Hellboy: Well, that's all for you!
Mignola!Hellboy: There you go.
- Cool Crown: The Crown of the Apocalypse, a fiery crown that floats above his head at all times, but is usually invisible. If it does appear, The End of the World as We Know It is near.
- Cosmic Plaything: Much to his displeasure and annoyance, he seems to be fated to continuously be reminded of his eventual apocalyptic destiny, often as violently as he could possibly be reminded. Even other BPRD agents mention that regardless of how tame the case seems to be, when Hellboy shows up things get violent, and he always catches the worst of it.
- Catchphrase: "Oh, crap!" Stories often end with "That's all for you!" (generally after he's killed something), and "There you go." Also, "Son of a—" is uttered whenever things go to hell.
- Cigar Chomper: In the Guillermo del Toro films, he's a huge fan of cigars as a tough and gritty Action Hero and monster hunter, and due to being a fireproof demon they don't bother him at all.
- Dark and Troubled Past: As he puts it:"I like not knowing. I've gotten by for fifty-two years without knowing. I sleep good not knowing."
- Dark Is Not Evil: Despite having horns and being half-demon, Hellboy is an utterly regular, decent, rather noble blue-collar guy, who doesn't have much patience for people telling him he should be evil.
- Deadpan Snarker: Hellboy has a very dry sense of humor and has a habit of snarking at his enemies.
- Did You Just Punch Out Cthulhu?: He killed Satan, and decimated most of Hell's population by himself during the seven years he was there.
- Does Not Like Spam: As a little boy, he hated "pamcakes" because they were yucky and he wanted noodles for breakfast instead. That is, until he had his first bite.
- Fertile Blood: In The Nature of the Beast, there's a legend that when the monk who first killed the St. Leonard Worm was injured fighting the dragon, lilies grew from where his blood fell. When Hellboy fights the Worm, lilies grow from where his blood fell as well. This is significant because Hellboy is a half demon and the prophesied Antichrist, but he is so good despite this fact that he becomes an Anti-Antichrist. This becomes a plot point in Ragna Rok: The blood from his Final Death revitalizes the Earth and allows new life to bloom after the Osiris Club and Liz raze the planet to kill the Ogdru Hem.
- Friend to All Children: He's really soft-hearted and friendly towards children.
- Gentle Giant: Hellboy is gentle with children, even sometimes when it's against his better judgment.
- Good Old Fisticuffs: His preferred method of fighting. His Right Hand of Doom is not just there for looks.
- Growing Into Their Paws: His Right Hand of Doom used to be as big as the rest of his body when he was an infant. His grown adult body leaves the Hand looking less disproportionate-looking.
- Half-Human Hybrid: The son of a demon and a human witch.
- Handicapped Badass: Losing an eye doesn't slow him down.
- Happily Adopted: By Professor Bruttenholm.
- Heroes Love Dogs: He had a beloved dog named Mac when he was young.
- Heroes Prefer Swords: Subverted. He's instinctively good with a sword and he's not a particularly good shot. Nevertheless, he goes into battle with a gun or just good old Five Fingered Mary far more often than a sword, just another sign of him contradicting his nature. During the battle against the Queen of Blood's army, he remarks that the axe he picks up midway through is more his style.
- Hide Your Otherness: Hellboy keeps sawing off his devil horns in an effort to fit in and deny his very, very evil heritage.
- Horned Humanoid: He files them down. As a kid however they were relatively long.
- Horrifying Hero: Hellboy is the demon who was supposed to bring about the Apocalypse, and he probably would have become a straight Humanoid Abomination if not for being raised like a human. He's personable enough that he isn't treated like the abomination he is, but by his very nature he was supposed to be evil.
- Human Mom, Non-Human Dad: His mother is the human witch Sarah Hughes while his father is the demon prince Azzael.
- I Just Want to Be Normal: Much of Hellboy's character revolves around his desire to live like a human as much as his demonic appearance would allow. But he's constantly annoyed by his demonic brethren and other supernatural forces reminding him of his destiny because he's really just trying to mind his own business.
- Inhumanable Alien Rights: Hellboy was granted "honorary human" rights by the UN in 1952, after his field mission in Brazil.
- Interspecies Romance: With Liz in the films, and Alice in the comics.
- Jerk with a Heart of Gold: He's gloomy, sarcastic, abrasive, and not much of a people person but beneath he's a big softy who genuinely cares about people and their safety.
- Kind Hearted Cat Lover: Hellboy adores cats and they love him right back.
- Knight in Sour Armor: He's gonna be sore in the mornin'.
- Lantern Jaw of Justice: The damn thing's enormous. It was big even when he was a skinny little kid.
- Made of Iron: He's ridiculously hard to kill, and is able to absorb huge amounts of punishment and remain standing. He'd almost be Nigh-Invulnerable if it weren't for the fact that he still tends to feel a great deal of pain and bleed everywhere when he does get injured.
- Military Brat: Sort of. He grew up on a military base (rather strongly hinted to be Area 51), and regarded the site personnel as family (though there were one or two who treated him as a science project).
- Mundane Fantastic: In the comics. Given his status as a big red demon-person and relative fame as a paranormal investigator, you'd think more people who met Hellboy in the comics would react with more surprise to his presence when he suddenly shows up to investigate things, but almost everyone he meets treats his appearance like nothing special at all, and frequently fail to even remark on it at all.
- No Shirt, Long Jacket: Hellboy's usual look in the comics.
- Older Than They Look: Hellboy's appearance is inhuman enough to make an apparent age not readily determinable, but he doesn't really seem to show his 60-80 years in which he has been on Earth (he was technically "born" in the 1600s, but doesn't seem to have aged until he left Hell). Alice Monaghan also looks about twenty years younger than she is, due to the influence of the fae.
- Orc Raised by Elves: Basically a baby Antichrist raised by good humans to be a hero.
- Parental Favoritism: Hellboy is his biological father Azzael's favorite son. His siblings aren't happy about their dad liking a newborn that hasn't done anything yet instead of them.
- Red Is Heroic: A red-skinned demon who fights for humanity.
- Red Is Violent: Maybe he's red and with the good guys' side, but also Good Is Not Soft.
- The Right Hand of Doom: He bears the Trope Namer. The Right Hand of Doom is all that remains of Anum, the Watcher that used that very hand to both create the Ogdru Jahad, and sealed them off. After his death, his Hand was passed down throughout history, until it fell in the hands of the Duke of Hell Azzael, who replaced his son's original arm with it so he could bring an end to all.
- Royal Blood: From both sides. Father was a Duke of Hell, mother was descended from King Arthur. After years of thorning the sides of his father's agents, it's his mother's family that nearly leads him to end the world.
- Screw Destiny: As seen in Wake the Devil:Hecate: Accept the truth of your existence or be destroyed! You cannot escape your destiny!
Hellboy: Gonna try.
Hecate: Time is coming to ring down the curtain on man. Already, the four horsemen are loose in the world. It is for us to darken the sun, turn the moon to blood, and put out the stars. Then you and I alone, forever, in the dark
Hellboy: Shut up! Not gonna happen... 'cause you're very, very ugly... and... you have a giant snake body!
- Smoking Is Cool: Rarely seen without a cigarette or cigar.
- Super Strength: He's awfully strong, which makes being hit by his hand hurt even worse than it already would.
- Super Toughness: Hellboy is very hard to hurt and harder to keep down for any decent amount of time, which is good for him, since he typically runs up against monsters that are just as durable and strong as him, if not moreso.
- Trademark Favorite Food: "Pamcakes." In fact, the very first time he ate them, he was lost to the forces of darkness forever.
- Trenchcoat Brigade: One of his trademarks is a coat and a big cigarette.
- Working-Class Hero: Hellboy himself is largely based on Mike Mignola's father, who was a cabinet maker. He'd often come home to his family with tales of horrific on-the-job accidents, including one careless fellow losing a hand, told in the nonchalant, unflappable manner that would become HB's trademark.
- The Unchosen One: After his death, all those forces of darkness who were counting on him to end the world become convinced they had the wrong guy after all.
Pyrokinetic Liz Sherman, a young woman suffering from Power Incontinence as well as struggling with self-esteem issues over childhood trauma stemming from when her powers first manifested. She was taken in by the bureau in 1974 where she learned to control her powers to some degree. Her trauma has left her bitter and she often left the bureau — only to return some time later.
In B.P.R.D., she manages to gain control over her powers after living with a society of monks for a few years, and gradually becomes significantly more powerful.
- Amplifier Artifact: The Hyperborean artifact Liz uses on the mountain-sized Ogdru Hem spikes her flame powers to the levels of a short radius nuke.
- Bad Powers, Good People: When she was young she accidentally killed a dozen people including her family. For a while, she believed her power was evil, but later she learns to control it.
- Can't Stay Normal: Has ditched the BPRD numerous times only to come back.
- Cursed With Awesome: Congrats Liz, you're one of the most unstoppable forces on the planet, if you can control your powers.
- Dreaming of Things to Come: Memnan Saa really does want to warn her, even if he's got his own purposes in mind. If only she would listen
- Dull Surprise: Liz Sherman's default expression for most of the Hellboy comics and movies. Justified, as she's supposed to be depressed and heavily medicated due to her tragic past, and in the later BPRD series, she gets better.
- Expy: Of Charlene McGee (from Stephen King's Firestarter). Has the exact same powers, a similar backstory, and even manifested her powers during roughly the same time period. Basically, she's what Charlene would be if she had the BPRD instead of The Shop and Hellboy instead of her father.
- Faux Action Girl: In the early days, Liz was usually the one to be possessed, kidnapped, used as an energy source, and, of course, rescued by her teammates. This is all despite her training, power set, and years as a B.P.R.D. agent.
- Finger Snap Lighter: Liz Sherman uses her pyrokinesis to light her cigarettes on occasion.
- Goth Girls Know Magic: A gothy girl who happens to be pyrokinetic.
- Hold the Line: By the time of Cometh the Hour she, along with Johann, has been reduced to this, fighting a holding action against the hordes of new Ogdru Hem spawned by Nunn-Jahad in an effort to buy time for the BPRD to evacuate their headquarters.
- Intergenerational Friendship: Soon became good friends with a thousands-of-years-old mummy named Panya.
- Kill It with Fire: Liz uses this a lot, obviously.
- Light Feminine and Dark Feminine: The Dark to Princess Nuala's Light in the movie sequel.
- Mundane Utility: Liz Sherman lighting her cigarettes with pyrokinesis.
- Older Than She Looks: Over fifty in real-time years, doesn't look a day out of her twenties in recent books.
- Powered by a Forsaken Child: She is used to power a machine in a BPRD issue.
- Psychic Powers: She seems to have some sort of power like this. She called Abe for help after her soul was used to fuel a machine; she has visions and dreams of the future and has apparently visited this future herself.
- Self-Made Orphan: When her powers manifested as a girl, Liz incinerated an entire city block and killed her parents, her brother and her dog.
- Survival Mantra: The fire is not my enemy, it is a part of me, it is mine.
- Took a Level in Badass: She was always powerful, but her lack of control over her abilities made her effectiveness questionable at best. Over the years she steadily gains more control. In Reign of the Black Flame she takes on the eponymous villain (who himself Took a Level in Badass to become a Physical God) and had a high powered brawl throughout New York City, destroying skyscrapers and giant monsters alike while her body became living fire. Holy shit.
- Took a Level in Kindness: Further understanding of her powers (and learning how to blow up Ogdru Hem) has significantly mellowed Liz out and made her more sociable.
- Uncertain Doom: After exploding to destroy the Ogdru Hem, the entire franchise's last shot is Abe's descendants finding her encased in some sort of mysterious crystal thousands of years later, leaving it possible that she's the only main character to survive the ending.
- Warrior Monk: Lived with a group of these and learned how to control her powers from them. Liz was very upset when they were killed.
- Wreathed in Flames: Anytime she really cuts loose with her powers, she tends to manifest an aura of fire all around her body.
A super-intelligent "icthyo sapien" and Hellboy's best friend. He began his life as Langdon Everett Caul in the 19th Century. Being involved with the Oannes Society, an occult organization who believed in life and all knowledge having come from the sea, he transformed into a fish man after an incident. He was found in 1978 in an abandoned laboratory beneath a Washington, D.C. hospital. After some efforts to wake him up (and some grueling tests from curious scientists) the amnesiac fish man took a new name and became an agent.
After an encounter with the Black Flame, getting shot by Fenix Espejo, and a second mutation, Abe left the B.P.R.D. and started wandering the post-apocalyptic United States. His travels are chronicled in the spinoff book Abe Sapien.
- Adaptational Ugliness: Abe went from reasonably handsome◊ (if fishy) in the comics and animated movies to a much more inhuman, fish-like appearance◊ in the films.
- Adaptational Wimp: In the movies, he's not as good a fighter, and his physical strength is downplayed.
- A Day in the Limelight: The Abe Sapien spinoff could be considered this and "Garden of Souls" is almost completely devoted to Abe Sapien with some supporting action for Daimio.
- Demonic Possession: At the climax of Seed of Destruction, he gets possessed by the spirit of Elihu Cavendish. It turns out to a rather benevolent example, since the ghost only used his body to hurl a harpoon through Rasputin's chest and snap Liz out of her hypnosis.
- Fish People: He's not dubbed "Icthyo Sapien" for no reason. Not only does he look like a fishman, he has all the abilities you would expect from one, such as being an incredibly good swimmer and breathing underwater.
- God in Human Form: Hinted. He is called "fish god" once or twice, and it's increasingly heavily hinted he might be an avatar or rebirth of Oannes the sea god.
- Identity Amnesia: At first, but investigating his past led to Abe remembering his past life.
- Made of Iron: He's nearly as tough as Hellboy is, having survived being shot three times by an angry monkey, tortured with iron brands, impaled through the chest twice, and once tossed around like a ragdoll by the Ogopogo Lake Monster.
- Mysterious Past: Not that mysterious anymore, but now he has a mysterious future (as seen in several of Lizs visions, he will play a role in the apocalypse and unexpectedly, he seems to be connected to Shonchin and the Hyperborean shamans).
- Named After Somebody Famous: The B.P.R.D. gave him the first name Abraham for Abraham Lincoln. It's explained that this was something of a dark joke, as a scrap of paper listing his species near where they first found him referenced the date Lincoln was killed.
- Non-Action Guy: In the films, Abe is shown as a solid non-action member of the team, and his fighting scenes often get him thrown around and barely managing to survive whatever they are facing. If anything, he only looks good in dodging maneuvers and aiming.
- The Ophelia: Cauls wife Edith Howard always had an unstable psyche. But after he disappeared, she went mad and drowned herself. She continued to haunt their house and tried to coax Abe into staying with her and becoming Caul again. He shows her her reflection in a mirror and she makes peace with her death.
- Put on a Bus: This happens to Abe in an awesome way in the B.P.R.D. story "The Dead". He returns to field duty... but not for long.
- Recurring Dreams: Abe had a weird one in the Plague of Frogs story arc.
- Super Strength: It's downplayed in the films, but Abe appears to be extremely strong in the comics, once even capable of tearing a stone block the size of his torso out of a castle wall he was chained to. His mutation in "Hell On Earth" explicitly made him even stronger.
- Stable Time Loop: After being stabbed and going into a coma, he somehow ended up in Victorian London and by watching and touching his former self somehow caused his transformation into a fish man in the first place.
- Shout-Out: As a humanoid fish man who apparently is still undergoing the process of further mutation into an even more fish-like state and his origins tied to a mysterious undersea city, Abe is something of a Deep One analogue for the Hellboy universe, especially with the revelation that Abe is effectively a highly evolved version of one of the Frog Monsters.
- Species Surname: Abe's last name is "Sapien" and his species is known as "Ichthyo Sapien"
- Tomato in the Mirror: One of the main things driving Abe's wandering at present is his deep denial about his similarity to the frog monsters.
- Touch Telepathy: In the films, he has vaguely-defined psychic powers involving his "unique frontal lobe", and they are based on touch — he can do psychometric readings of objects, and share the images he gains from these telepathically. He can also detect life and read memories or emotions through his hands.
- Tastes Like Friendship: After saving Abe from being vivisected Hellboy gives him a sandwich.
- They Would Cut You Up: Curious scientists wanted to dissect him but he was saved by Hellboy. He later saved Roger from the same fate.
- Truly Single Parent: Is easily killed by Rasputin in Ragna Rok but explodes into thousands of eggs that grow into Icthyo Sapien babies that take over humanity's place as rulers of the planet.
Kate was a professor of history at New York University before joining the B.P.R.D. in 1984 as a consultant. She is specializing in folklore and has a vast knowledge of anything occult, mystical or folklore. Kate became a regular cast member of the B.P.R.D. spinoff series where she acts as the special liaison to the 'enhanced talents' agents before eventually getting promoted to director. Kate and Hellboy are exes and good friends and she blames herself for encouraging him to leave the bureau.
- A Day In The Lime Light: B.P.R.D.: The Universal Machine is all about her searching for a way to bring Roger back to life.
- Badass Bookworm: In B.P.R.D.: The Universal Machine Kate is captured by an ageless marquis who wants to trade her for either Rogers corpse or Abe Sapien. While unable to get the book she needed from the marquis to restore Roger back to life, she did manage to escape on her own in an awesome way she recognized the ring of the marquis as a ring belonging to King Solomon and by destroying it she released a demon who was a prisoner of the marquis and who promptly took him to Hell.
- Big Good: Kate is the one running the B.P.R.D.'s attempt to stop the apocalypse.
- Break the Cutie: Trying to save humanity with limited success has slowly chipped away at Kate's friendly attitude and empathy.
- Badass Normal: One of the few non-superpowered, non-military trained agents, but can still hold her own.
- Despair Event Horizon: Suffers this in Part One of Cometh the Hour as a result of the Ogdru Jahad's inexorable advance towards the BPRD headquarters in Colorado and being confronted with the necessity of having to evacuate said base, in addition to the stress of fighting a losing war to save humanity for years.
- Geek: Kate Corrigan is a occult/mythology geek (it was her day job before she joined the BPRD).
- I Want Grandkids: In the (probably) non-canon Curse of the Haunted Doily, the ghost of Kate Corrigan's mother bugs her about this.
- Interspecies Romance: Hellboy and Kate dated for a brief time before ending the relationship on good terms.
- Klingon Promotion: Is essentially running the B.P.R.D. since all of her superiors kept getting killed.
Roger, a big energy-absorbing homunculus, was discovered in 1996 in Romania by B.P.R.D. agents Liz Sherman, Bud Waller and Sidney Leach. He was activated when Liz (who subconsciously wanted to get rid of her pyrokinesis) touched him. Liz went into a coma and Roger into a killing spree. Roger felt guilty and prayed to God to be killed. He then encountered his "brother", who was trying to get revenge on humanity by sacrificing Kate and using a giant homunculus made of human fat. Roger saved Kate, used Lizs power to melt the giant body and killed his brother. He restored Lizs pyrokinesis and — being without an energy source again — went into a coma for three years. He was restored by Abe Sapien using an overdose of electricity and became an agent. Roger is killed in the pages of B.P.R.D. by the villain The Black Flame.
- Artificial Human: Being a homunculus, Roger is naturally this.
- Back from the Dead: Subverted. They even spend an entire story arc letting you think it's gonna happen.
- The Big Guy: After Hellboy leaves the Bureau, Roger takes his place as the team muscle.
- Cigar Chomper: He becomes one during the war on the Frogs, under the influence of Ben Daimio. Liz thinks that because of his (relative) youth and inexperience, he tends to "imprint" on people like a bird - at first Hellboy, and after he leaves, Ben.
- Collector of the Strange: A harmless version. Roger collects all sorts of stuff and junk and hangs it up on strings from his ceiling. One of his collected things turns out to be very important in order for Liz to burn Katha-Hem to dust.
- Gentle Giant: Doesn't much care for violence. This starts to change, however, after Daimyo takes him under his wing.
- Innocent Fanservice Guy: Roger only wears his boots. Played for Laughs at least once.
- Kindhearted Simpleton: In the B.P.R.D. series, his characterization tends more towards this.
- Last of His Kind: The last of the Mischrasse homunculi.
- Manchild: Roger is very childlike. He looks up to and wants to please Ben Daimio like he were his parent. He collects all sorts of stuff and his spirit even becomes a child in a dreamlike world after he died.
- Sacrificial Lion: His whole team was blown to pieces in the B.P.R.D. spinoff series.
- They Would Cut You Up: Abe prevented some B.P.R.D. scientists from doing so.
- We Can Rebuild Him: Sadly no, Kate, you cant, cause the book you needed to do so is now in Hell, along with the marquis.
- Why Am I Ticking?: The Bureau puts a bomb in Roger for fear of him going rogue. This is the major catalyst (but not the only reason) for Hellboy to leave.
Field director of the B.P.R.D. following Bruttenholm's death and Hellboy's departure, the one in charge of leading missions. Daimio was a U.S. Marine Captain, but was killed, then brought back to life. He eventually has to be killed when the were-jaguar spirit keeping him alive starts killing agents.
- And I Must Scream: As he explains to Abe later, he is conscious and aware while in the Jaguar form, but has no control over what it does. Meaning Ben watched helplessly as he slaughtered dozens of his own men in Killing Ground.
- Back from the Dead: Under originally mysterious circumstances. He died, and cut himself out of a body bag three days later, with half his face missing, and very much to his surprise.
- Bait the Dog: Played with. He seems to be a good, decent person, respected and even looked up to by everyone on base. And he is. But the jaguar inside of him is not. As Mignola once said, despite being a good man, he was one of the worst things that ever happened to the B.P.R.D.
- Crazy Survivalist: By New World, he's ended up here.
- Death Seeker: Once he realizes he'll never be free of the jaguar curse.
- Demonic Possession: Plays a major part in his backstory.
- Good Scars, Evil Scars: Notably subverted with Daimio. He has hideous scarring along the left side of his head, and is missing an ear and most of his left cheek. Blame the jaguar demon that's now inhabiting his soul.
- Our Werebeasts Are Different: Eventually revealed to be the source of his rebirth. But he has no control over his werejaguar form, and kills countless B.P.R.D. personnel in Killing Ground before he escapes.
- Race Lift: Subverted. Ed Skrein was planned to play Daimo in the reboot movies, but upon learning the original characters race, he gave up the role, unprompted. Wisely avoiding backlash, the production team then cast Daniel Dae Kim.
- Semper Fi: A former Captain in the United States Marine Corps.
- Shell-Shocked Veteran: He's had a rough time of it. He was dead for three days, wouldn't you be too?
- Superpowered Evil Side: Thanks to the aforementioned Demonic Possession. In Killing Ground, it wakes up.
- Tragic Monster: He never asked to become the host of the jaguar cult's assassin, and he endured a lot in his ultimately futile quest to contain it.
The founder and director of the B.P.R.D. and Hellboy's adoptive father. Is killed by the frog creatures at the beginning of the first Hellboy comic and in the middle of the movie.
- Badass Bookworm: Back in the 1940s certainly. He once even parachuted out of a rocket filled with vampires!
- Big Good: Was this for the B.P.R.D. when he ran it.
- Defiant to the End: In the first film, he makes it clear to Rasputin and Kroenen that no matter what, he will always see Hellboy as his son.
- Died in Your Arms Tonight: Subverted. He doesn't die in anyone's arms, but the first thing Hellboy does when he finds him is just hold him.
- Face Death with Dignity: In the first film, Kroenen fatally stabs him after Rasputin assures him that his death will be quick. Trevor calmly accepts it.
- Motherly Scientist: Gender flipped. He adopts Hellboy after he was summoned into this world.
- No Pronunciation Guide: Averted. Where the Professor is a major character, at least Once an Episode someone attempts to pronounce "Bruttenholm" as it's written and are told it's pronounced "Broom." (This is real phenomenon with certain English names.)
- Posthumous Character: Trevor is only shown in flashbacks and prequels, which show how important he was to the team.
- Plot-Triggering Death: His death alerts the Bureau to the dangers of the frog creatures and Rasputin.
Director of the BPRD since Trevor Bruttenholm resigned in 1982. When the team relocated to Colorado he disappeared.
- The Bus Came Back: Returns in Part Two of Cometh the Hour, where he coordinates the evacuation of the BPRD Headquarters with Kate in front of the advancing Ogdru Jahad and its Ogdru Hem spawn.
- King on His Deathbed: Is revealed to be terminally ill in The Devil You Know #6, when he speaks with Hellboy at the BPRD helicarrier's command center from his bed at a D.C. secure facility. In his words, he has had "many new illnesses" in the last few years, since the start of the war against the Ogdru Hem. It is indicative of how bad things generally are that Hellboy believes that a dying Manning may yet live long enough to see how it all turns out...
- Obstructive Bureaucrat: At first, he tended to follow the directions of his superiors in opposition to the opinions of his team. This included planting a bomb in Roger(unwillingly, but still), which drove Hellboy to resign. After this he gradually evolved into a Reasonable Authority Figure.
- Put on a Bus: Manning basically disappeared from the series when the team went to Colorado.
A German medium who was reduced to his ectoplasmic form after a séance gone wrong - he was the only spiritual medium worldwide lucky (or perhaps unlucky) enough to be outside his body, on the astral plane, when a mysterious Chinese artifact incinerated every other powerful medium, all at once, leaving him with no physical body to go back to.
- Adaptation Name Change: Became Johann Krauss in the film, purely so Hellboy could crack an "SS" joke.
- Aesop Amnesia: At the end of Killing Ground Johann seems remoreful over the fact he wasn't there to help stop Ben Daimio in his were-Jaguar form sooner. And that maybe indulging in booze and sex while he should have been at his post was selfish. Cue the start of Hell on Earth where Johann is avoiding work to sit in a lab alone with a new body the bureau is attempting to make for him. Made extra callous by the fact Kate is overworked due to all the horrific apocalyptic disasters currently happening. One panel even has Johann casually reading a book in said lab after Kate trusted him with command while she was away.
- The Blank: Due to his lack of a physical form.
- Character Development: Has gradually become colder, more bitter and often more callous, as his connection with regular humanity has waned. In the end, he overcomes this and sacrifices his soul to save humanity.
- Classical Anti-Hero: Johann is a very good person, but he has some deep flaws. His desire for a real body has sometimes overriden his good judgement, and being dead has made Johann somewhat callous.
- Did You Just Punch Out Cthulhu?: Johann partially merged with the universe and and channelled every last trace of Vril in it to completely destroy Nunn-Jahad, and in doing so, he proved that the Ogdru Jahad are not invincible.
- Empathic Shapeshifter: At the end of Killing Ground, his ectoplasmic form is temporarily that of his recently-destroyed new body, but reverts to his old one as he realizes just how much his selfishness has cost others.
- Gratuitous German: When he loses his temper. Allmachtiger!
- The Hedonist: In Killing Ground, when he (temporarily) finds a new, super-powered body, he spends as much time as he can working out, masturbating, and eating huge amounts of food (so much that the custodial staff complained he was single-handedly raising their monthly garbage tonnage). Many of the issue's problems could have been solved, and innocent people saved, if he hadn't snuck off-base to carouse with pretty ladies and booze at the worst possible moment.
- Heroic Sacrifice: Johann destroyed Nunn-Jahad and saved the world, at the cost of his own life.
- Hold the Line: By the time of Cometh the Hour he, along with Liz, has been reduced to this, fighting a holding action against the hordes of new Ogdru Hem spawned by the Ogdru Jahad in an effort to buy time for the BPRD to evacuate their headquarters.
- Killed Off for Real:Due to how he killed Nunn-Jahad, the sheer strain of channeling all the Vril in the universe burned out his soul.
- Our Ghosts Are Different: As Kate Corrigan points out, Johann isn't technically dead. He just doesn't have a body anymore.
- Powered Armor: At the end of the "Modern Prometheus" story, he upgrades to the Sledgehammer armour (!) allowing him to one-shot Ogdru Hem and fight off the Black Flame.
Panya is an ancient mummy who was unwrapped by the Heliopic Brotherhood Of Ra in the late 19th century, before being kidnapped by Abe Sapien's old colleagues, the Oannes Society. She was taken in by the BPRD after Abe tracked down the society in "Garden Of Souls."
- Friend to All Living Things: She has a psychic rapport with animals (and certain humans), and has a great affection for them, particularly the Oannes Society's chimeras.
- Intergenerational Friendship: She quickly hit it off with Liz Sherman and Fenix.
- Killed Off for Real: Died when Nunn-Jahad destroyed the HQ, along with Kate and a lot of people.
- Merlin Sickness: Possibly. When she first arrived at the BPRD, she was weak and bed-ridden. As she grew stronger she took to a wheelchair and was generally more active, and there were hints that this might be significant. Then, by the end of "Hell On Earth", she's capable of walking again.
- Mission Control: In any other series, the ancient, prophecy-spouting mystic would be allowed to putter around the secret base until exposition was needed. But Kate gets sick of Panya's freeloading and sticks her in front of all the monitors watching the news.
- Vagueness Is Coming: What her original role was.
An accountant that gets promoted to field agent and goes on a few missions, the biggest one being following Fenix Espejo across country. Eventually promoted all the way to head of the BPRD by The Devil You Know.
- Ascended Extra: Played a small supporting role in "The Universal Machine", then kept coming back and working his way up. Now he's a main character.
- Fantastic Racism: He does not trust Abe because of his appearance.
- Mauve Shirt: Not a really important agent early on, but not dead meat either. By this point he's got as much Plot Armour as you can have in an Anyone Can Die series.
- Obstructive Bureaucrat: Agent Devon was turning into one before he got Reassigned to Antarctica.
- JerkAss: He is really dickish to Abe Sapien...
- Jerkass Has a Point: ...but he's right that simply ignoring Sapien looking almost exactly like the frog creatures is silly.
- Reassigned to Antarctica: Got stuck with following Fenix around the US, probably for insulting Abe.
A very easily excited Bureau scientist who seems to know a great deal about the Ogdru Jahad. He tends to freak out whenever the case relates to the Ogdru Jahad, and often launches into gothic prophecy about whatever they seem to be facing.
- Cloud Cuckoo Lander: Whatever fried his brain left him with a tenuous connection to reality. To the point that his co-workers are somewhat tired of O'Donnell's rantings, which in this universe of prophecies being worth everything is saying something.
- These Are Things Man Was Not Meant to Know: He comes off across as one of those Lovecraft protagonists who went crazy after reading the Necronomicon or something similar, only he's still lucid enough to speak with (most of the time) because the BPRD can help manage his psychosis with medications.
Once, agent Ted Howards was a rational, friendly, and perfectly mundane Bureau agent, sent with two companions to investigate what turned out to be a nineteenth-century occultist temple in Chicago. Here he discovered and picked up an unimaginably old sword - while in the distant past, a primitive warrior chief named Gall Dennar is handed the same sword when his father is killed in battle. Both lose consciousness and, from that point on, their destinies merged: when Howards is found by his companions, his personality has undergone a complete change into that of a stoic, silent, and unfriendly berserker warrior, yet more competent than old Howards ever was.
- Absurdly Sharp Blade: His sword is perfectly capable of cleaving through a man's skull even when thrown.
- The Berserker: He wears no armor and wields no other weapon than his sword, simply launching himself at his foes and tearing them to pieces.
- Past-Life Memories: Howards' seem to have been taken over by, or merged with, Dennar's.
A teenage Seer that can predict when Ogdru Hem would attack and other calamities. Fenix initially led a group of other survivors around, protecting them from monsters before getting recruited into the B.P.R.D. Has a pet rottweiler named Bruiser.
- Disposable Vagrant: Played mostly straight with her group of runaways: almost none of them are named, they have almost no lines, and most of them serve little addition to the story other than as monster-chow; Fenix also sees them as a surrogate family, and feels responsible when one of them dies.
- Green Thumb: Tends a garden outside the B.P.R.D. Colorado headquarters with Liz and Kate.
- Intergenerational Friendship: With Panya. Later with Liz, who sees a lot of her younger self in Fenix.
- Jerkass: Of the angry teenager variety.
- Queen of the Homeless: Well, not queen per se, but she is most certainly the leader of her band of drifters and runaways, as her abilities allow her to warn them of dangerous areas to avoid.
- The Runaway: Doesn't have any parents, and when we fist meet her she is train hoping with a group of other teenage backpackers trying to stay one-step ahead of the undead mutants and crab creatures.
- Screw This, I'm Out of Here!: Her general attitude when things get dangerous. Justified, as her powers allow her to see danger before it arrives, giving her a chance to avoid it. Considering that physically she is just a normal teenage girl, it's not like she could do much on her own in most dangerous situations even if she chose to stay.
- After one-too-many attacks by the crab creatures leaves Fenix's group scattered and decimated, she is left with two options: either vainly try and regroup (and most likely end up monster chow), or risk going cross-country with Devon and joining the B.P.R.D. She chooses the latter.
- Took a Level in Kindness: Joining the B.P.R.D. really helped Fenix find purpose in her life.
"The Lobster" has two histories. The real Lobster was a New York vigilante in the 1930s, and fought Nazis, spies, gangsters, saboteurs and villains like Memnan Saa and the Black Flame, branding their foreheads with the "Lobster's Claw" after their death. He was hired by the US government on the eve of the Second World War and died in a secret assault on the headquarters of the Nazi space programme. He proved as tenacious in death as in life and his ghost held on for years, eventually aiding Roger and Liz in the modern age as a ghost.
None of this is known to the public however, and the US government denies the existence and any knowledge of "The Lobster." Eventually he became a Pulp Magazine star, written by a hack who claimed to have met the real deal. A series of abysmal film serials followed, starring Vic Williams. Then, in the 50's, Mexican director Eduardo Fernandez created somewhere between nine and twelve low-budget films about Lobster Johnson, portraying him as a luchador hero. In fact, these were the source of the name "Lobster Johnson." Before the world ended and Hell On Earth began, rumours abounded that a reboot might be in order, possibly directed by Guillermo del Toro.
He has his own spinoff comic, Lobster Johnson.
- Anti-Hero: A solid Type 3 Pragmatic Anti-Hero. Throughout his short career in the 30s he personally killed hundreds of gangsters, Nazi saboteurs, cultists and monsters. And he only gets more dangerous when he's dead.
- Cult Classic: Both film series are notoriously terrible, but many enjoy them anyway, including Hellboy.
- Guns Akimbo: His usual fighting style, firing two automatic pistols at once.
- Incoming Ham: The only time Lobster shows any emotion besides seriousness is when he's attacking.Fear the Claw!
- Made of Iron: Even before he became an immortal ghost, the Lobster could take a licking and keep on ticking, despite seemingly being an ordinary man up against horrifying occult threats and dieselpunk super-science.
- Masked Luchador: "Lobster Johnson" in the Mexican wrestler pictures. They invariably open with a woman driving a car with a corpse in the back seat, which comes to life and becomes Lobster Johnson when she sings to it.
- Mysterious Past: But it was probably dark and troubled.
- Nazi Hunter: Both before and during World War II.
- Polyglot: Knows multiple languages, including Turkish and Japanese.
- Secret Identity: The pulp novels claim he was crippled millionaire William Johnson. The real-life reader has never seen him without his mask.
- Shrouded in Myth: Until Roger and Hellboy meet his ghost, even Hellboy had only heard rumours of his real existence, from the GIs who raised him.
- The Stoic: Unlike many of the more-hammy pulp heroes of the day, unless he's actively shooting up a bunch of bad guys, or gritting his teeth or howling in pain under torture, the Lobster's face never really moves from the same serious expression, no matter how over-the-top or strange the situations he finds himself in.
- True Companions: His gang. Unfortunately, the group as a whole had a high turnover rate.
- Two-Fisted Tales: His solo comic deliberately takes cues from the pulp stories of the early 20th century, while still tying into the comic's Myth Arc.
- Unfinished Business: Seemingly what kept him hanging around after his death. He eventually finds a sort of happiness back where he died.
- Urban Legend: This is the main reason why all the in-universe stories about him are pulpy and wildly incorrect.
- Vigilante Man: As the brutal, gun-toting reaper of the criminal underworld.
- Zorro Mark: His lobster claw.Lobster Johnson: "Here is the claw!"
Those Wacky Nazis: "Nein! Nein!"
A Wendigo case the B.P.R.D. had to deal with. Unfortunately, due to the nature of the Wendigo curse, Hellboy can't simply kill Daryl or else the curse will move to someone else, so they have to lock him up.
- And I Must Scream: His imprisonment. They can't kill him without passing on the Wendigo curse to his killer, so they have to lock him up. They give him a picture of his family in the hopes it'll give him comfort, before he gradually forgets his former life and becomes the Wendigo inside too.
- Mercy Kill: He killed Daimio when his curse overtook him.
- The Speechless: By the time he appears again, he lost his ability to speak, but he still has humanity left in him.
A child Hellboy rescued from fairies. Years later she would return to help Hellboy.
- Changeling Tale: Her first appearance as a baby in "The Corpse". Notably, her changeling replacement would also go on to be a major character.
- Official Couple: She and Hellboy fall in love when he meets her as an adult.
- Older Than They Look: She refers to it as "something the fairies left her." When she reappears in Hellboy's life the late 00s, she's roughly 49-51 years old, but looks to be in her mid to late-20s.
- The High Queen: Revealed in the newest Hellboy in Hell. She seems to have taken on the role of the departed Queen Mab.
A demon that takes the appearance of a little Russian girl. Varvara helped Trevor Bruttenholm after World War II by giving cryptic but helpful warnings. In the present day Varvara's been captured by the Russian Special Sciences Services and imprisoned in a magical bell jar.
- Big Red Devil: Her default appearance. Interestingly in her own daydreams she still imagines herself as a little girl.
- Last of His Kind: Is the last surviving demon lord of Hell, on account of having been imprisoned on Earth when the lesser demons rose up against their masters upon Hellboy's arrival in Hell.
- Light Is Not Good: In Mike Mignola's dark, Chiaroscuro-filled artwork, Vavala is drawn with a bright white dress, bright blond hair, pale white skin, and is seemingly unaffected by shadows at all. She probably does it deliberately to mess with everyone.
- In Love with Your Carnage: Implied to be why she likes humans so much and sides with them.
- Nominal Hero: At least she likes to help out the heroes in-between mocking people with their horrible fates.
- Sealed Evil in a Can: Sealed by the SSS. Until she is released by SSS Director Iosif Nichayko in response to one of the Ogdru Jahad breaking free from its prison and attacking Earth.
- Token Evil Teammate: The only malevolent demon on team humanity.
Iosif Nichayko is the field director of Russia's Special Sciences Service, the Russian equivalent of the B.P.R.D., and a magical zombie in a special containment suit. Has helped the B.P.R.D. fight off a number of Ogdru Hem and considers many of them his friends, especially Johann Kraus. Is also Varvara's jailer.
- The Alcoholic: Between Armageddon, his own death, and Varvara, Iosif has a lot of reasons to drink vodka.
- From Nobody to Nightmare: Iosif Nichayko was just some kind-hearted grunt in the Soviet military before joining the Special Sciences Service for extra pay, babysitting a healing artifact, dying, being brought back as a zombie, and eventually overthrowing freaking Varvara as the Director of the SSS decades later. Guy developed some serious Chessmaster abilities.
- Kid with the Leash: Not a kid, but same idea. He is in charge of containing Varvara, and is absolutely terrified of her getting out because he knows she will exact terrible revenge on him. Which is an indicator of how bad the situation has become that he eventually frees her from her prison, knowing the horrible fate that awaits him.
- Who Wants to Live Forever?: He is not happy with his continued unlife, but can't kill himself until the world is safe.
- Our Zombies Are Different: A magically revived Soviet Soldier that was initially mindless and in charge of protecting a magical set of armor. Once the Bureau stole that he regained sentience.
Sir Edward Grey is an agent working for Queen Victoria as a one-man equivalent of the B.P.R.D. in Victorian England. In the present day he follows his own agenda, and occasionally acts as a Spirit Advisor to Hellboy. Stars in his own spinoff comic Sir Edward Grey, Witchfinder.
- Absurdly Sharp Blade: Owns the Hyperborean sword that will eventually make its way to Ted Howards, via the Heliopic Brotherhood of Ra.
- And I Must Scream: In 1916, he was cursed with eternal life and then torn apart by Amdusias, a Duke of Hell, after Grey successfully stopped the Order of the Silver Star's attempt to summon him. Amdusias then dragged Grey down to hell with him, and his pieces were strewn along the river Acheron, until the creatures who lived there sewed him back together.
- British Stuffiness: Started off like this. Over time, his experiences with the supernatural pushed him more towards a very British Deadpan Snarker.
- Character Development: Goes from a stuffy gentleman who believes all magic is evil, to a much older and wiser man and incredibly strong warlock, who speaks as an equal to Hecate, the Baba Yaga and Dagda himself, and has become friends with an African witch doctor.
- Enemy Mine: Teams up with his enemies, the Heliopic Brotherhood of Ra, to fight Vladimir Giurescu and his vampire army in 1882.
- Occult Detective
- Those Two Guys: Might be developing this with Mohlomi, as the two appeared together a number of times after Mohlomi's passing on from the world. It's eventually revealed in City of the Dead that the two already met for the first time back in 1882, when Grey fought Vladimir Giurescu.
An extraterrestrial being who was sent to kill the infant Hellboy and avert the Apocalypse. In the end he decided he couldn't go through with it, deciding instead to monitor Hellboy as he grew up in the service of good. Debuts as a ghost in The Conqueror Worm and stars in the one-shot spin-off comic The Visitor: How and Why He Stayed.
- Aliens Are Bastards: Very much averted. Can't kill an innocent, even when they're destined to bring the Apocalypse. Seems to be a species characteristic, since his superiors, although skeptical, decide to back his decision.
- Alliterative Name: His human identity is "Michael Mathers".
- Early-Bird Cameo: As early as "Seed of Destruction", we saw members of his species monitoring the Ogdru Jahad's tombs and attempting to prevent their release.
- Hero of Another Story: Did his part to stop Ogdru Hem incursions during the decades he was observing Hellboy.
- Magic Tool: His "Prism", a glowing green thingamabob the size of a deck of cards.
- MayflyDecember Romance: Marries an Earthling during his decades on our world, but his lifespan is a lot longer than a human's, and he's distressed when her mind decays into senility while he remains young.
- Mysterious Protector: Hellboy never even notices him, but the Visitor's been present at several significant events in his history and even lent a hand to keep HB alive when necessary.
- The Watcher: Kept an eye on Hellboy, unseen, for most of his life to make sure he doesn't get on the path to releasing the Ogdru Jahad. He even saw white lilies spring up in Hellboy's shed blood, a story where Hellboy fought alone, and so knew he had chosen rightly when he spared him.
A powerful sorceress who was imprisoned by the Britain's witches for 1500 years before she was brought back to life to lead the Wild Hunt.
- Anti-Human Alliance: The Queen of Blood gathers one to destroy mankind. Unfortunately for them, she has no intention of restoring their world.
- Big Bad: Of the 2019 film.
- Full-Frontal Assault: Her nakedness only adds to her creep factor.
- Hero Killer: She killed Hellboy.
- King Arthur: Her true identity is revealed to be Nimue, the sorceress who seduced Merlin, stole his secrets and imprisoned him. She was driven mad by the Ogdru Jahad.
- Lady of Black Magic: A powerful sorceress who has been alive for centuries, with vast demonic and magical powers at her call.
- One-Winged Angel: In her final fight with Hellboy, the power of the Ogdru Jahad turned her into a dragon-like monstrosity. It was not enough.
- Taking You with Me: After Hellboy mortally injured her, she used the last of her strength to tear his heart out and kill him.
The Dragon of Revelation, the Seven Who Are One, the Seven Gods of Chaos, destined to bring about The End of the World as We Know It. Created by Anum, given life by the darkness, then sealed away by Anum, but not before giving birth to the Ogdru Hem. Only Hellboy and his Right Hand of Doom can set them free to destroy the world.
- Cool Crown: All of them have green flames shaped like crowns floating behind their heads.
- Crystal Prison: They're trapped inside a giant, cloudy yellow crystal. Well, six of them still are, at any rate...
- Demonic Possession: Ogdru Jahad can "link" their minds with someone who catches their interest, vastly empowering them but warping their bodies to resemble them, as they did with Nimue and the Black Flame.
- Dinosaurs Are Dragons: Their true forms resemble dinosaurs. Specifically hadrosaurs of all things. Mignola may have chosen hadrosaurs for their elaborate crests, representing the crowns worn by the Dragon in the bible.
- Dragons are Demonic: The Ogdru Jahad are seven dragon-like monsters prophesied to destroy the Earth, currently trapped within seven cocoons somewhere in deep space. Just about every other villain is trying to accelerate their coming or delay them by killing Hellboy (who is prophesied to wake them). Hellboy himself being an Anti Anti Christ, he ends up slaying an avatar of them, but it still isn't enough to prevent the apocalypse.
- Draconic Abomination: They are seven vaguely draconic eldritch entities usually fused into one body. Anything related to them, including the mere sight of them, can induce madness as Professor O'Donnell found out the hard way.
- Greater Scope Villains: Many of Hellboy's enemies seek to set them free.
- Nigh-Invulnerable: As Nunn-Jahad demonstrated, their physical forms are nearly impossible to destroy, being completely immune to anything the BPRD and the US government threw at it. Nukes did not even scratch it. The only thing that could hurt and ultimately kill it was a nearly immeasurable amount of Vril.
- Not So Invincible After All: It took Johann giving his life to do so, but he proved that the Ogdru Jahad can be killed permanently, but a massive amount of Vril is needed to do so.
- Monster Progenitor: They spawned the Ogdru Hem from their very bodies, and as Nunn-Jahad showed, they can do so at will, dozens at a time.
- Overarching Villain: The Ogdru Jahad, a group of Eldritch Abominations Hellboy was initially placed on Earth to summon, and spends the series stopping cultists of theirs from finishing the job.
- Sealed Evil in a Can: Anum sealed them off shortly before his death. And Hellboy's got the key right in his hand (or rather, it is his and Anum's hand). Seed of Destruction shows there's some strange alien race that guards their prison but they won't be much help if anyone tries in earnest to bust the inmates out.
- Tentacled Terror: They are a mix of Lovecraft and Babylonian myths, are often portrayed as enormous tentacled masses beyond our universes borders. They're also the Big Bad of the entire setting, are responsible for the creation of Hellboy and have intended for him to bring them into our reality to usher in the End of Days.
The 369 Offspring of the Ogdru Jahad, imprisoned on Earth at the dawn of time. Hellboy and co. are able to fight off a few of them, but their mass reawakening kicks off the aptly titled Hell on Earth series.
- Always Chaotic Evil: Unlike the demons of Hell, the Ogdru Hem are all horrible monster animals.
- Eldritch Abomination: Just like their parents. The first of them to be introduced, Sadu-Hem, can best be described as a massive pillar of tentacles and crustacean legs.
- Kaiju: Their smallest offspring are about the size of train cars, they are usually as big as skyscrapers.
The head of Project Ragna Rok and the one who originally summoned Hellboy to Earth. Based on the real-life Russian mystic.
- Amazing Technicolor Population: He's consistently drawn with blue skin, most likely to emphasize his undead nature.
- Astral Projection: After he found his way to the Ogdru-Jahad's temple in the Arctic, he connected his mind and spirit to Sadu-Hem, which allowed him to see the imprisoned form of his master. He spent decades in this state before Professor Bruttenhom and the members of the Cavendish expedition unwittingly woke him up.
- Back from the Dead: Quite a few times. He's truly dead now, the last fragment of his soul used by the Baba Yaga to strengthen Koschei the Deathless.
- Bad Boss: Surprisingly averted. While all serve in his machinations to unleash the Dragon and bring about the end, he doesn't treat his followers badly unless they explicitly fail him, as Roderick Zinco finds out.
- Big Bad: In the 2004 film, and the first three volumes of the comics.
- Healing Factor: Part of what makes him so hard to kill. In their first encounter, Hellboy blows half of his head off with his pistol only for Rasputin to heal in a matter of seconds.
- Healing Hands: He offhandedly mentions that he was capable of healing the sick with a touch, back before his first death.
- Historical Domain Character
- Historical Villain Upgrade: Obviously. He had some contact with Baba Yaga while he was alive, but he got a real upgrade when he threw in with the Ogdru Jahad after his (first) death.
- "It" Is Dehumanizing: Consistently refers to Hellboy as "creature" when they first meet.
- Mind Control: He was able to mentally command all of the people at the base camp of the Cavendish expedition to transport Sadu-Hem down the mountain it was entombed in and onto a boat.
- Occult Blue Eyes: His pupiless eyes glow an eerie blue, which contrasts with Hellboy's red eyes.
- Our Liches Are Different: Part of the reason he keeps coming back. When he met Baba Yaga, he gave her half of his soul, which she buried in the roots of Yggdrasil.
- Overarching Villain: Grigori Rasputin is the most prominent of the Ogdru Jahad's acolytes, and Hellboy's most personal foe, as the one who summoned him to Earth in the first place. While he's killed in The Conqueror Worm, his acolytes remain a thorn in the BPRD's side.
- Rasputinian Death: In addition to the (embellished) real-life version (poisoned, shot, castrated and dumped in the Neva), in "Seed Of Destruction", he's impaled with a harpoon by Abe, burned by Liz and finally his bones crushed by Hellboy. In "Wake The Devil" his spirit dwindles as his schemes fail, and after "The Conqueror Worm" Hecate reduces his spirit to a speck, which the Baba Yaga keeps. Then, finally, she breathes the last of that into Koschei the Deathless in a last-ditch attempt to kill Hellboy, which also fails. And that was that.
- Resurrective Immortality: In the film. Every time he died, he was resurrected with a part of his god inside his body.
- Surrounded by Idiots: He considered everyone he worked with during Project Ragna Rok to be total idiots compared to him.
- Telepathy: One of his many powers. He was able to read Professor Bruttenholm memories after coming in contact with him, which is how he learns about Hellboy.
- The Undead: Carries on as a ghost in the comics after his death.
- Tragic Villain: The comics version comes across as rather tragic, as his schemes to control the direction of the world's end continually unravel, leaving him an increasingly impotent and humiliated figure raging against his ultimate irrelevance in the grand scheme. Tellingly, when the apocalypse does come about, he has almost nothing to do with it.
- Villain Respect: In the first film, he has enough respect for Professor Bruttenholm to make sure he gets a quick and painless death.
- Wound That Will Not Heal: Even after he becomes a spirit, he retains the hole in his chest from when the possessed Abe Sapien threw a harpoon through him. It also has ethereal smoke constantly coming out of it.
A recurring Nazi Mad Scientist villain who often appears to menace Hellboy and friends with his army of cybernetically enhanced gorillas known as the "Kriegaffes", despite being nothing but a floating head in a jar. He was a childhood friend of Kroenen's and was responsible for turning him into a cyborg after he lost most of his body in a lab accident, but Rasputin refused to let him into Project Ragna Rok because even Rasputin thought he was too crazy. Nonetheless he eventually found himself working for the Ogdru Jahad anyway.
- Argentina Is Nazi-Land: Lived in a secret lab in the jungles of South America after WWII.
- Big Bad: Of The Science of Evil video game.
- Brain in a Jar: He's lucky enough to still have his face, at least.
- The Bus Came Back: He made a couple of appearances in the early years of the title (fittingly for the villain of the second-ever story, and its first "supervillain"), only to be killed off in "The Conqueror Worm". He wouldn't reappear until the 1946 series over a decade later, though his head showed up in BPRD... then he came back for real at the start of BPRD: The Devil You Know.
- Facial Markings: Has a swastika on his forehead, Charlie Manson-style.
- Hijacked by Ganon: Starts out as an independent evil mastermind but winds up serving the Ogdru Jahad just like every other bad guy in the series.
- Maniac Monkeys: His favored minions. BPRD 1946 gives him bionic chimps in addition to the usual gorillas.
- Meaningful Background Event: His head seems to be part of Mr Pope's office collection of Nazi supervillain memorabilia.
- Ungrateful Bastard: After Kroenen revives him he starts criticizing his latest evil plan and insulting him.
- Villainous Friendship: With Kroenen. He really doesn't get along with the others, though.
A Nazi scientist who was part of Project Ragna Rok. The one character who has the biggest difference between the comics and the movie, in the comic Kroenen is a Nazi scientist, in the movie he's a undead clockwork assassin.
- Adaptational Badass: In the films, he's a nigh-unkillable assassin as opposed to a meek scientist.
- Affably Evil: His comic incarnation is actually a pretty nice guy, despite being a Nazi who wants to sacrifice the world to an Eldritch Abomination. He's friendly and polite to his colleagues and goes out of his way to help his best friend Herman even when he knows it might get him in trouble.
- Alien Blood: Over the decades, the blood in his veins dried up into dust.
- All There in the Manual: Kroenen's film backstory is revealed in a series of comic panels in Hellboy: The Art of the Movie and in the special features on the DVD. And his comic version's in the companion book.
- Blade Below the Shoulder: 60 years ago, these were his primary close range weapons. In the modern day, he prefers bladed tonfa.
- Body Horror: His movie incarnation surgically removed his own eyelids, lips, fingernails, and toenails, as well as repairing himself with a clockwork heart, a robotic hand, and a steel rod in place of a broken piece of his spine. His comic incarnation may be even worse off, considering that gas-mask like face is his actual skull.
- Combat Sadomasochist: His backstory in the films stated that every day, he'd whip himself with a branch of oak and find pleasure in the pain. And let's not forget his "surgical addiction."
- Cyborg: His heart is a strange clockwork device and his left hand is a mechanical prosthetic.
- Darth Vader Clone: Dressed in all black, including a black mask, prominently wields blades, is a cyborg with an artificial hand, and he's the chief enforcer of the Big Bad. There's also the comparison of him being a Nazi while the Galactic Empire relies on their style.
- Diagonal Cut: Slices open Samael's prison with a single clean, delayed cut.
- Evil Is Not a Toy: He's the only one of Rasputin's disciples who considers Vladimir Giurescu to be too uncontrollable and believes that trying to use him in their plans is a bad idea.
- Freak Lab Accident: In the comics he was blown up in a lab explosion and turned into a cyborg by his friend Herman von Klempt. In Wake the Devil the two are caught in a second freak lab explosion. They got better.
- Gadgeteer Genius: Kroenen invented all the bits and pieces that make him what he is today.
- Genius Bruiser: A Master Swordsman who invented his own cybernetics.
- Immune to Bullets: In the films, he simply shrugs off being shot on account of having no vital organs to hit and his blood turned to sand.
- Implausible Fencing Powers: In the first film he can not only block bullets with his blades, he can also deflect back at the shooters.
An evil fairy creature that hates Hellboy for thwarting his plan to kidnap Alice Monaghan. He eventually throws in with the Queen of Blood.
- Changeling Tale: The actual changeling of "The Corpse".
- Chekhov's Gunman: Nobody expected him to come back after his first appearance, but he went on to become one of the most important characters in the series.
- Evil Is Not a Toy: He released Grom, a giant pig-man monster that fought against Cu Chulainn himself so it would kill Hellboy. Unfortunately for him, one of the first things Grom does when it gets free is eat him.
- Full-Frontal Assault: In his original form, he didn't wear any clothes.
- Humiliation Conga: He's burned with a horseshoe and thrown in a fireplace, his plan to abduct Alice is ruined (which brings his race closer to extinction), the pig demon he recruits to fight Hellboy eats him, and then when said pig demon is killed its body shrinks down until his hide is skintight on him, condemning him to look like a pig forever.
- Unwitting Instigator of Doom: Nice job destroying England, the world, your own people, and the human race, Gruagach.
- Well-Intentioned Extremist: At first, his plan is to attack the human world to stop the slow fade of the fairies. When he learns that this can never work, he instead decides to simply not die quietly. The great irony being that he ends up bringing about a situation where humanity must do the same thing.
- Woobie, Destroyer of Worlds: Most of what he does is out of pride for his doomed race. Mixed a little with his desire to free himself from the pig's body he's trapped in. It's also revealed that in the distant past he was a bold warrior with human lover who accidentally cost him his status.
A goddess from Hyperborean times who was "born out of the shadow of the moon, and delivered from the belly of a wolf".
- Abhorrent Admirer: Hecate is in crazy stalker love with Hellboy. Unfortunately, he's not the kinda guy who goes for metal-skinned vampire snake women who want to kill every living thing on Earth.
- Honey Trap: Hecate's backstory involves her using a variation on this. She was an ascetic who lived in the mountains until she came down to the main city of the (soon to be doomed) kingdom of Hyperborea. She seduced King Thoth of Hyperborea and while he was asleep broke into his forbidden garden.
- Big Bad Duumvirate: In Wake The Devil, she's one of the major threats to Hellboy and his team alongside Rasputin. They aren't working together though.
- Impaled with Extreme Prejudice: One of the many ways she dies, courtesy of Hellboy.
- Information Broker: Hecate proceeds to the nearest Hyperborean temple and pisses out all the knowledge the ingested angels had given her and PAINTS the walls with it, effectively giving away world-killing knowledge for free.
- I Have Many Names: Hecate, Heca-Emen-Raa, Black Heccata, Lamia, Lilith, Coyolxuahqu or just the Black Goddess. She's been around a long time.
- I Know Your True Name: Due to some shenanigans with Giurescu and the conditions of her last resurrection, Hecate now has the body of (and thus in a way, true name of) Ilsa Haupstein. It comes back to bite her, bigtime.
- In Love with Your Carnage: Has this for Hellboy's 'destined' role as Anung Un Rama, World-Ender. Hellboy doesn't reciprocate.
- A Lighter Shade of Black: Compared to the Queen of Blood, anyway. This isn't saying much.
- Mama Bear: She doesn't take kindly to anyone hurting her vampiric "children", as Hellboy finds out the hard way.
- Monster Progenitor: Among others, she's the "mother" of Giurescu the vampire, and may in fact be the mother of all vampires, if the prehistoric "Cold People" (who worship her and need to be staked through the heart to stay dead) are any indication.
- Never My Fault: She claims she gives knowledge freely, what people do with it is their business. Seems fair, until you remember that the last time she did the this people of Hyperborea used her knowledge to destroy themselves.
- Snake People: After what she did, Thoth cursed her with a half-snake form.
- Things Man Was Not Meant to Know: Three cast off angels. Hecate didn't like the king keeping all this knowledge from his people, so quite rationally she ATE the three angels and with them all their knowledge and decides to share it with everyone.
- Weakened by the Light: Whether it's due to her own nature or Thoth's curse, sunlight is lethal to her.
- Why Won't You Die?: Godhood usually does not guarantee of immortality in this series. Gods like Perun can be bumped off in just a few pages, but Hecate takes the cake in terms of being tough to kill. Or, at least, keep dead. While not quite as persistently resurrected as Grigori himself Hecate has returned at least four separate times and in increasingly bizarre ways.
A legendary Slavic lich. He lived in Baba Yaga's "Russia that never quite was", a parallel dream dimension. He is literally impossible to kill unless his soul is exposed or drained. He serves as Baba Yaga's (reluctant) Dragon in "Darkness Rising". His backstory is revealed in Koshchei the Deathless, a miniseries told to Hellboy during his stay in Hell as Framing Device.
- Anti-Villain: He was never evil by choice and loathes all the evil deeds he did in life.
- Bow and Sword, in Accord: Uses both sword and bow with equal levels of skill.
- The Dragon: Serves, grudgingly, as Baba Yaga's throughout his story arc. Her leverage over him is that she will allow him to die after he's killed Hellboy, which makes Koschei a...
- Death Seeker: He cannot die unless his phylactery is exposed and only Baba Yaga knows where it is. He longs to die, and it is implied the world bores him.
- Defeat Equals Friendship: He was originally one of Hellboy's enemies in life. When meeting him in Hell, it's shown they hold no hard feelings towards each other, as they share a drink in a bar and Koshchei tells his backstory to Hellboy.
- Fallen Hero: He used to be a brave warrior whose courage and bravery earned him the hand of a princess... Unfortunately, said princess had a lover on the court and had him killed in his sleep. His quartered remains were found by the dragon that he originally served, who then turned him into a lich to save his life.
- Magic Knight: In addition to being a swordsman, he learned magic from his dragon master and has the powers of a lich.
- Moral Event Horizon: An in-universe example. He wanted to get rid of his humanity so he used a monster's deadly song to kill everyone in a town after promising its king that he would kill the monster for them, in order to deliberately kill "Koshchei the Man" and become "Koshchei the Devil".
- Noble Top Enforcer: Serves as this to Baba Yaga, as Koschei has in his own words 'Done a hundred black deeds' but doesn't seem proud of them. He does Kick the Dog a bit by killing Vasilisa with an arrow.
- Noble Demon: Despises Baba Yaga's sadism and tells Hellboy to die quickly, to rob the witch of her 'sport' during their final confrontation.
- Our Liches Are Different: Koschei keeps his soul inside a needle which is inside an egg which is inside a duck which is inside a hare which is inside a goat, which puts him deep into Properly Paranoid territory. The original legend manages to go EVEN FURTHER: His soul is inside a duck which is inside a hare which is inside a goat which is inside a steel/iron chest on an island that is either moving or impossible to locate unless you've been there. His backstory reveals that he became a lich after a dragon saved his life.
- Villain Protagonist: He is the focus in the Koshchei the Deathless miniseries, where he tells Hellboy his life story in a bar while they are both in Hell.
- Unwitting Pawn: How he became Baba Yaga's slave in the first place. She tricked him into killing his dragon master saying that his brood would enslave mankind. Turns out she ordered to get rid of him because she couldn't stand a greater power than her own. When he learned of this treachery, he tried to kill her but couldn't find her. Then he unwittingly revealed the location of his soul to her, allowing the Baba Yaga to enslave him.
A recurring moniker, notable for being surrounded by impossible black flames. The earliest Black Flame that we know about was called Raimund Diestel and fought Lobster Johnson and the Sledgehammer Armor during World War II. The second Black Flame is Landis Pope, Roderick Zinco's successor as head of the Zinco Corporation, who allied with the Frog People and later took over Manhattan.
- Arch-Enemy: To the Sledgehammer armor, whoever is wearing it, since it seems to be one of the few things that can stand up to him. Also to Liz, whose firepower matches his but isn't evil.
- Badass Boast: As seen in Reign of the Black Flame:Liz: So I killed you, huh? Good to know. This time I'll get it right!
The Black Flame: (emerging unscathed from a point blank fire blast) You won't.
- Captain Ersatz: Mr. Pope is a pretty blatant parody of David Xanatos.
- Dragged Off to Hell: Pope is carried away by the frogs after the destruction of Katha-hem. When he reappears, what sanity Pope had left seems to be gone.
- Even Evil Has Loved Ones: When Diestel's wife is killed he abandons the fight to go to her, and allows himself to be arrested.
- Evil Is Not a Toy: Pope believes that he can control both the powers of the black flame and the frogs. He is wrong.
- Fallen Hero: Diestel was a member of Sarah Jewell's party that attempted to rescue the missing girls that had been abducted by the Cult of the Black Flame in 1923. He helped in their rescue, but ended up becoming the first incarnation of the Black Flame in the process. By 1932 he is an inhuman, cold-blooded killer, and from 1933 onwards he serves the Nazis.
- HeelFace Door-Slam: After realizing what his actions have unleashed, Pope is repentant. He apologizes to Liz for killing Roger... who, unaware till now he'd been responsible at all, responds by allowing him to be dragged away.
- The Juggernaut: The original Black Flame was immune to anything less than a cannon shell, and that didn't kill him either.
- Legacy Character: The first Black Flame, Raimund Diestel, appeared in the 1930s, and was a mystical assassin until he was killed by the Sledgehammer in 1944. His suit and remains were recovered decades later by Landis Pope, who had a (at least partially) nonmagical copy of the suit created to allow him to interact with the frogs more easily.
- Origin Story: The standalone miniseries "Rise of the Black Flame", revealing more about Diestel and Kamala.
- Shell-Shocked Veteran: Raimund Diestel. A German naval officer, he served on the S.M.S. Emden during World War I before its destruction by an Australian cruiser. Having enough of the war, he deserted and made his way to Siam (Thailand), where he became an opium addict.
- Technicolor Fire: It's in the name. Notably, Pope's initial version of the costume burned blue, and turned black after the frogs empowered him and he became the real Black Flame.
- The Undead: He looks like he has a skull for a head. Pope's was initially a helmet, and after he returned it appeared his head has become mummified; it's not clear if this was the case for Diestel.
- Took a Level in Badass: He is revived in Return of the Master. In Reign of the Black Flame, we discover that he's now practically a Physical God whose life force is connected to every living thing in the ruins of New York City, hence making it impossible for Liz Sherman and the BPRD to kill him without resorting to mass murder.
- Unwitting Pawn: His true purpose is just to burn, and light the way for the Ogdru Hem. The frogs allowed him to "control" them so they could get him to take on this role.
Memnan Saa was born Martin Gilfryd in 19th Century London and has interacted with Edward Grey, the Lobster and the BPRD. Spent most of the first part of B.P.R.D. tormenting Liz with apocalyptic visions of the future.
- Dark Messiah: This is how Memnan Saa sees himself.
- From Nobody to Nightmare: Memnan Saa began his long life as Martin Gilfryd, a mortal curator for the British Museum's Egyptology Department. He would go on to study multiple ancient magicks and lost arts from teachers across the globe, even in places unknown to modern man, gaining a great deal of untold power. At the height of his ability he's basically unstoppable.
- Mighty Whitey: Invoked, but ultimately subverted.
- Unwitting Pawn: For all his claims of being the savior of humanity, its implied hes actually being manipulated by the Ogdru Jahad when he is shown among their servants Rasputin and the Black Flame during the Queen of Bloods transformation into one of them.
- Villains Never Lie: Repeatedly claims that he has never lied to Liz. It eventually becomes obvious this is at best only metaphorical truths and at worst simply his own delusions of messiah-hood.
- Visionary Villain: He plans to save (and later, rule) the world, because he doesn't believe the BPRD have the nerve to make big decisions in the coming apocalypse.
- Well-Intentioned Extremist: Memnan Saa's primary motivation was to preserve the human race and civilization. He was willing to resort to any means necessary, however, and he even dismissed Kate Corrigan's offer of an alliance between himself and the BPRD by claiming that the latter was not ruthless enough. Of course, his secondary motivation is to rule over the survivors as a god, so there's that too.Memnan Saa: Your bureau, your governments, will try to save all of this earth. That is childish! The war has already begun. You believe you've had your victories. You will believe that again. While the truth is, little by little you are losing. So, there is only one question.. a question you will never be able to answer. How much are you willing to lose... to win?
- Yellow Peril: His look has deliberate shades of this as he is essentially a wannabe Mighty Whitey trying to be Fu Manchu.
A powerful vampire lord, Vladimir Giurescu was chosen by the goddess Hecate to be her son, and his veins run with her blood. Whenever he is mortally wounded, he can be taken to a secret temple built for the goddess beneath Castle Giurescu, laid out on an altar in the light of the full moon, and a few ritual sacrifices later hes good as new again.
- A God Am I: He believes that since he can recover from almost anything, he's closer to a god than a man.
- Back from the Dead: Giurescu nearly drowned in a frozen river and was brought back to life as a vampire after his father sacrificed all their dogs and their servants. If he is killed or mortally wounded (which happens a lot), his remains are deposited in an special ritual room to bring him back.
- Brutal Bird of Prey: A vampire who turns into a scary eagle instead of the usual Bloodsucking Bat.
- The Dragon: To Hecate in Wake The Devil.
- The Dreaded: By Adolf Hitler of all people. His presence was so dark and unnerving that he ordered his arrest and execution.
- Evil Overlord: He inherited his father's estate and for three centuries, ruled the surrounding area with iron fist and paying Hecate in blood as tribute.
- Expy: He shares many traits with Dracula such as having "vampire brides" and resembling his real-life inspiration. It's also mentioned he attempted to create a secret empire on England during the 1880s, but he was stopped by the Witchfinder Edward Grey, similar to Dracula's own plans in the novel which took place in a similar time period.
- Feathered Fiend: Giurescu can shapeshift into an eagle and he can control crows to spy and attack his enemies.
- Lunacy: The light of the full moon can heal his wounds.
- Never Found the Body: The B.P.R.D. tries to move his skeleton to their headquarters for safekeeping after Hellboy kills him, but it disappears at the Bucharest airport. The epilogue of Wake The Devil states that it was never recovered.
- Our Vampires Are Different: Giurescu became a vampire through a magical ritual instead of being bitten and turned.
- Polyamory: He took many wives over the course of the centuries, and even had more than one at once.
- Red Baron: Dubbed as "Giurescu the Devil" by Napoleon Bonaparte.
- Undying Loyalty: To his "mother" Hecate. He even gives his newly restored life to resurrect her after she's killed by Hellboy.
- Unholy Matrimony: Not only with his vampire brides, but he also had Ilsa Haupstein as a lover.
A legendary witch of Russian folklore, Baba Yaga is one of Hellboy's recurring foes. She is often pulling the strings from behind the scenes, and is surrounded by a strange cast of characters.
Oh, and she flies around in a pestle and mortar.
- Artificial Limbs: Her legs are made of wood
- Evil Old Folks: She's an ancient evil witch and certainly looks the part. She's also Rasputin's grandmother.
- Eye Scream: She ran into Hellboy years ago in a graveyard. The encounter ended with Hellboy shooting out her left eye.
- "The Reason You Suck" Speech: Delivers a simple but poignant one to Rasputin at the end of Wake The Devil for his failure in Romania and for allowing himself to become little more than a pawn to the Ogdru Jahad."Like it or don't, you are what you have allowed yourself to become... Nothing."
- Walking Shirtless Scene: She's not a fan of shirts, which in this case, is not sexy in the least. Thankfully, her chest is always covered one way or another.
A vampire encountered by Professor Bruttenholm after the end of World War II. He is angry with Hitler and the Nazis for betraying Vladimir Giurescu and his family, and plans revenge against humanity for the Nazis' crimes.
- Even Evil Has Standards: Konig is a brutal vampire lord, but he was appalled by the Nazis' treatment of his fellow vampires. Granted, he did not like Giurescu and personally thought he deserved the fate he brought upon himself for trying to forge an alliance with the Nazis, but the execution of Giurescu's wives was what drove Konig into launching his vendetta.
- Evil vs. Evil: A Vampire Monarch hates the Nazis for their betrayal of his fellow vampires.
- Fantastic Racism: Like all vampires, he considers humanity beneath them and seems offended that Giurescu tried to ally himself with the Nazis and viewing them as their "equals".
- Feathered Fiend: Similarly to Giurescu, Konig shapeshifted into a bird instead of bats - in his case, an owl.
- Nazi Hunter: A rare evil version of this trope, since he personally hunts downs Nazis for their crimes against vampirekind.
- Revenge Before Reason: His pursuit of vengeance nearly exposes the vampires to the rest of the world.
- The Unfought: The B.P.R.D. doesn't even come close to fighting him; he is instead executed by his fellow vampires for breaking The Masquerade.
- We Can Rule Together: Konig makes this offer to his fellow vampires to come out of the shadows and attack the humans now (i.e., in the late 1940s) instead of putting off their attack to the pre-arranged year in the future. They opt to execute him for nearly exposing them to the world prematurely.
- White Hair, Black Heart: He had long, white hair and was evil and bloodthirsty, like other vampires in this setting.
Exclusive to the Films
The main villain of the second Hellboy film, Nuada Silverlance is the crowned prince of the Clan Bethmoora elves (also known collectively with the other magical races as 'the sons of the earth') and the last of the warrior elves. Nuada is anti-human and focused on preserving his own kind and other non-human life by destroying all humans, and has returned from exile to awaken the Golden Army to carry out the genocide of humanity.
- Anti-Villain: Nuada; he is sympathetic because, though his methods are excessive, his motivations are understandable. He's spent centuries, possibly millennia, watching the mythical creatures that once ruled the world fade into the background as humans expanded and the royal family has been reduced to ruling from sewers. Furthermore, humans violated the ancient, eternal treaty between them and the magical beings; a treaty Nuadas father King Balor made because he regretted the slaughter and decided not to commit genocide on humanity... then the descendants of those people (perhaps unknowingly) threw Balor's mercy back in his face and violated the treaty's terms. Nuada wants to take the planet back from the humans in the name of the fey beings before their kind dies out completely.
- Badass Normal: Played with. Although he is an elf with a psychic link to his sister, none of his racial traits seem to actually help directly in combat, save perhaps, being an elf. Also, he seems to age slower than humans, judging from the flashback scenes where a young Hellboy's father tells his son a story about The Golden Army, including the Elves that initially used the aforementioned army as their secret weapon.
- Big Bad: In the second movie. His desire to reawaken the Golden Army and restart the war against humanity drives the plot.
- BrotherSister Incest: There's some definite undertones to the way he acts around Nuala, and he's clearly jealous when he realises she's grown close to Abe. del Toro even calls him an "incestuous little bastard" during his commentary on the film.
- Calling the Old Man Out: Subverted, as Nuada is in the wrong despite his valid concerns.
- Can't Argue with Elves: He makes some really good arguments against humans that Hellboy is unable to refute.
- The Determinator: He waited hundreds, if not thousands, of years to call upon his army to wipe out humanity and return his people to their rightful place.
- The Evil Prince: See above, though he did kill his own father to obtain a piece of the crown, yet showed regret for it.
- The Exile: Self-imposed in protest over the peace treaty between his people and the humans.
- Fantastic Racism: Nuada despises humans, though he has reasons for doing so. However he is reasonable, even friendly, to non-humans.
- Fragile Speedster: Nuada is an extremely skilled hand-to-hand combatant, gracefully dodging or parrying everything that comes his way while using his spear to retaliate. Most of Hellboy's fight against him is just trying to pin the slippery elf down. Once he does, though, Nuada is beaten pretty much instantly.
- Kill All Humans: Prince Nuada's stated goal is to use the Golden Army to wipe out humanity and take back the world for the fey.
- Pet the Dog: Several moments including his Villainous Friendship and a literal one where he kills the guards at the entrance to the B.R.P.D headquarters but spares the guard dogs after persuading them not to attack him, petting one.
- Polar Opposite Twins: While both are very dedicated to their people and culture, they go about it in the exact opposite way: Nuada believes destroying humanity after humans forgot a sacred pact with the Elves and destroyed the forests is the right thing to do, while Nuala wants no bloodshed and wishes to help humans prevent a war. He does much of his fighting himself, having been training for years alone, while Nuala can't fight, but is willing to work with the BPRD to stop him.
- "Reason You Suck" Speech: Gives several in the film.
- Red and Black and Evil All Over: Wears a red-and-black samurai-like outfit during the climactic scene.
- Royals Who Actually Do Something
- Supernatural Gold Eyes: Like Hellboy, alluding to his magical heritage.
- Villainous Friendship: With Wink. He was dismayed by Winks death and sought to avenge him.
- Warrior Prince: As detailed above, he is more than a capable combatant. And, as the son of King Balor, he qualifies for both sides of the trope.
- Woobie, Destroyer of Worlds: See Anti Villain
Nuada's twin sister, also psychic, who shares a bond with him. She is, however, entirely against his plan to destroy humanity, and is willing to fade away if it means keeping the peace as her father wanted. She meets Abe Sapien and teams up with the BPRD to stop him, developing mutual feelings for the fish man in the process.
- Beauty Equals Goodness: Despite her people's somewhat creepy appearance, she's very pretty and delicate-looking- the novelization describes Abe as "thunderstruck" when he first sets eyes on her.
- Color Motif: Her main gown is blue to symbolize her future relationship with Abe, with gold to hint at her magical nature and heroism. She also takes interest in a poetry book the exact color of her gown, enjoying a particular poem Abe also loves.
- Damsel in Distress:
- Nuada eventually takes her back and tells Abe if he wants to see her again he'd better give up the crown piece.
- Played with; when they first meet and Nuala is on the run from her brother with the crown piece, Abe assumes she needs his assistance, but she assures him it's the other way around.
- Dating What Brother Hates: Nuada is 'not' happy to see her even refer to Abe by his first name, inferring she is fond enough of him to do so.
- The Determinator: Like her brother, she refuses to give in- but her agenda is the exact opposite of his.
- Friend to All Living Things: She was implied to be this in the original script, with a pet monster guard dog protecting her and feeding fruit to magical creatures in a cage.
- Hair of Gold, Heart of Gold: She's very kind and forgiving, with platinum blonde hair.
- Heroic Sacrifice: Kills herself to ensure Nuada does not try to take command of the Golden Army again.
- Lady and Knight: The Bright Lady to Abe's White Knight.
- Light Feminine and Dark Feminine: Light to Liz's Dark.
- Love at First Sight: How Abe fell for her. For Nuala, however, it was more when they had a LoveAtFirstPsychicTouch moment.
- Pimped-Out Dress: Has three: her main blue gown with gold accents, a black and red gown she wears during her first appearance, and a pale golden Japanese-style gown in the climactic scene.
- Polar Opposite Twins: While both are very dedicated to their people and culture, they go about it in the exact opposite way: Nuada believes destroying humanity after humans forgot a sacred pact with the Elves and destroyed the forests is the right thing to do, while Nuala wants no bloodshed and wishes to help humans prevent a war. He does much of his fighting himself, having been training for years alone, while Nuala can't fight, but is willing to work with the BPRD to stop him.
- Our Elves Are Different: Nuala is considerably kinder to humans than The Fair Folk tend to be in folklore...
- Proper Lady: Nuala is the picture of grace, manners, and kindness (initial mistrusting of Abe aside when they met), not holding a grudge at all against humanity for shoving her people into the background.
- Red and Black and Evil All Over: Strongly averted. She wears one red and black dress but is as far from evil as it gets.
- Silk Hiding Steel: The picture of elegance, but she threatened Abe with a knife to the throat when she caught him following her around the market.
- Supernatural Gold Eyes: Like Hellboy, alluding to her magical heritage.
- True Blue Femininity: Her main dress is a lovely shade of blue, and she's very genteel.
