HELLBOY (Bio)

History and Discovery

The creature which would become known as Hellboy first appeared the night of December 23, 1944, when the evil mystic Grigori Rasputin summoned Hellboy to Earth with the help of the Third Reich.
Baby Hellboy appeared miles away in a churchyard in East Bromwich, England where he met a crack team of American soldiers lead by 1st Sgt. George Whitman sent to investigate the mysterious Nazi ritual.
They were accompanied by Professor Trevor Bruttenholm of the Bureau for Paranormal Research and Defense (B.P.R.D.), Professor Malcolm Frost, Lady Cynthia Eden-Jones, and the Torch of Liberty, a WWII-era costumed superhero.
Bruttenholm befriended the creature, christening him Hellboy. The child was raised in secret by the U.S. government and trained to be a paranormal investigator.

Childhood

After he appeared in a church on an island off the coast of Scotland, Hellboy was taken to an air force base in New Mexico where he grew up under the guidance of Trevor Bruttenholm and the fledgling B.P.R.D. Hellboy interacted with personnel at the base such as U.S. General Norton Ricker, and the dog, Mac. In 1952, when he was eight, Hellboy officially joined the Bureau for Paranormal Research and Defense as a full time agent.

Early Career

Hellboy aged greatly in body, although somewhat less in mind: while appearing to be a full-grown middle-aged man, he still had the rebellious fire and attitude of an adolescent. He became adept in many supernatural and paranormal subjects such as possession, haunting, exorcism, enchantments, holy amulets, and sacred artifacts. He eventually became a full-fledged field agent of the B.P.R.D. under Trevor Bruttenholm. In the years following World War II and the demise of the Nazi regime, Hellboy traveled the world, encountering and defeating numerous supernatural beings and disturbances such as werewolves, vampires, and encounters with the deranged Nazi scientist Herman Von Klempt (see World's Greatest Paranormal Investigator) Hellboy also encounters minor deities, mythological creatures, and beings of folklore. He had a notable encounter with the Baba Yaga (see The Baba Yaga). In the year 1952, Hellboy was granted honorary human status by the United Nations.
Two years later, Hellboy was approached by the Osiris Club to slay the Saint Leonard worm, an alligator-like monster. This battle was in fact a test of Hellboy's true virtue, resulting in lilies that grew from his spilled blood, which seemed to confirm his good nature (see The Nature of the Beast). A short time later, Professor Bruttenholm sent Hellboy to help a Professor Edmond Aickman with the King Vold myth. Aickman was obsessed with a possible reward, and manipulated Hellboy into begrudgingly completing Vold's chosen tasks (see King Vold).
In 1959 Hellboy was in Ireland and embarked on a mission to rescue a baby, Alice Monaghan. In order to do so, he had to bear a corpse to its final resting place. Overseeing the assignment was the King of the Daoine Sidhe, who would harbor interest in Hellboy in the near future (see The Corpse).
In 1979 Hellboy was sent to aid a once famous physical medium, Mister Tod. Tod, using drugs to enter a trance, accidentally released a cosmic monster which created a body for itself with Tod’s ectoplasm (see Goodbye Mister Tod). This was Hellboy's first encounter with the spirit of an Ogdru Hem; he was able to defeat the creature with an herb. In 1982 tracked down the infamous Countess Ilona Kakosy, a vampire. Hellboy slayed her after she tried to distract him with a disturbing vision (see The Vârcolac).
In 1991, Hellboy is called in to assist fellow Bureau agent Pauline Raskine. The B.P.R.D. was investigating a newly discovered hidden basement in a mansion owned by former a Doctor Carp. Carp was a Grand Master of the Golden Lodge, a temple of the Heliopic Brotherhood of Ra located in New York. Hellboy has knowledge of the H.B.R. and refers to them as crazy. Upon entering the room Hellboy was magically warped through time to the year 1902, where he had to contend with the sadistic Doctor. Carp managed to get a sample of Hellboy’s demonic blood to use on a chimpanzee, turning the ape into a bloodthirsty monster (see Dr. Carp's Experiment).

The Cavendish Hall affair

However, it wasn’t until the groundbreaking Cavendish Hall mission that Hellboy truly met a challenge which posed an extreme threat to him or his fellow agents Abe Sapien and Elizabeth Sherman, a woman with uncontrollable pyrokinetic abilities. It began when Hellboy met with his mentor Trevor Bruttenholm, who was trying to tell Hellboy a crucial memory disturbing the Professor. Suddenly, Bruttenholm was mysteriously killed when a spawning of frogs entered the room, and an angry Hellboy faced off with a humanoid frog monster.
A mission was sent to the haunted Cavendish Hall mansion, consisting of Hellboy, Abe and Liz to question the elderly Mrs. Cavendish, whose well-known family heritage Bruttenholm mentioned as he tried to remember what to tell Hellboy seconds before his death. Mrs. Cavendish was a widow who lost her three sons a few months before, when they, along with Trevor Bruttenholm, together explored the Arctic in search of a legendary temple. She said it was her family's curse that every male in the line, starting with Elihu Cavendish, became obsessed with retrieving something from the Arctic. Many would never came back.
In truth, the Cavendish boys along with Bruttenholm, made it to a secret temple in the Arctic. There they had come across Grigori Rasputin, who had been hibernating for years in service to a terrible cosmic monstrosity, the Ogdru Jahad. Rasputin had become the creatures’ only hope of entering our world in order for them to unleash the Apocalypse on Earth. A dormant Ogdru Hem, Sadu-Hem one of the 369 children of the Ogdru Jahad, was accidentally awoken by the team. It's breath transformed the three Cavendish brothers, and their guide while Bruttenholm was able to kept by Rasputin, after reading his mind and discovering his link with Hellboy. They boarded a ship and when they arrived in America, Bruttenholm was allowed to escape with a fragile memory, in order to lure Hellboy to Cavendish Hall.
Hellboy and his partners elected to stay the night at Cavendish Hall, to further explore any possible clues. Unbeknownst to the agents, the revived Rasputin had been manipulating events in order to draw Hellboy closer to him, intent on forcing Hellboy to fulfill his purpose as the Harbinger of Armageddon. Rasputin was the one who had summoned Hellboy to this world back in 1944, and had been patiently waiting for his chance to return and retake control of his ‘son.’
Upon discovering the presence of Rasputin, who had willingly revealed himself that evening in a vain attempt to coerce Hellboy’s loyalty, Hellboy refused this destiny. Having been raised by his mentor in the ways of good, he then tried to slay the now furious Rasputin.
Abe Sapien managed to kill Rasputin by throwing a harpoon through his chest. However, he was actually being possessed by the spirit of Elihu Cavendish. The ghost of Cavendish desired vengeance against Rasputin for the murder of his family. Liz Sherman awoke from her trance and summoned a firestorm that killed Sadu-Hem. Hellboy succeeded in rejecting his purpose and delaying the End of Days. Rasputin’s body was destroyed and his spirit was forced to flee, vowing that Hellboy would fulfill his purpose in the end, whether he wanted to or not.

More Career Highlights

What follows are a few worthy-of-note adventures of Hellboy and his partners following the Cavendish Hall incident:

1994, Griart, The Balkans: Hellboy and Kate Corrigan visited a town decimated by the angry ghosts of werewolves. It became a revenge mission after Father Kelly, Hellboy's associate, was murdered by a living werewolf. Kate's first sighting of a ghost occurred during this mission.

1995, Scotland: Hellboy returned to the ruined church where he first appeared in the world, and had a dream-vision of his origin: His mother, as a young woman, had cavorted with the demon Prince Azzael, and on Walpurgisnacht (a night of great significance to witches) conceived Hellboy.

1998, Lizarza, Spain: Hellboy met with Adrian Frost, the son of Malcolm Frost. Hellboy related his life story to Frost, and the two realized that Hellboy's stone right hand was the key to triggering the Apocalypse. Hellboy has decided keep the hand lest someone else retrieve it and use it.


The Giurescu Affair

In 1997, the second major turning point in Hellboy’s journey of discovery regarding his original purpose on Earth began as a mission to Romania, to investigate the theft of an ancient box containing the corpse of Vladimir Giurescu, a Napoleonic officer who was in fact a vampire.
The legend went that whenever Giurescu was injured in battle, his servants would bring his body back to his home castle, where the rays of the full moon would mystically revive him back to full health. In 1882, Giurescu, posing as a foreign nobleman, attempted to start a secret evil empire to conquer England. This caught the attention of the Nazi party during the 1940s, who then sent a delegation lead by Ilsa Haupstein to recruit the immortal vampire to their cause. The meeting went badly, resulting in Hitler ordering the arrest and murder of Giurescu’s vampiric followers, nicknamed his “family.” He and his ‘family’ were beheaded and stabbed through the heart with stakes, and then burned; their ashes sent to Hitler.
However, this was not the end for Vladimir Giurescu. In 1997, a former Nazi named Howard Steinman/Hans Ubler was shot to death inside his own museum, and a crate marked “Giurescu Lot #666” was taken. It is assumed that Ubler had stolen the remains of Giurescu during his Nazi days and had hidden the deceased vampire inside the museum for the last few decades. Now it appeared that Giurescu’s followers, lead by Ilsa Haupenstein, had come to rescue their master and bring his remains to Castle Giurescu, where the next full moon would revive him.
The problem was that Castle Giurescu had never been found, for its location has always been hidden. B.P.R.D. agent Kate Corrigan made three rough guesses at possible locations of the castle, and three groups of agents were sent to each location in case one of them is the real deal. Hellboy went solo to the first site, while Agent Clark and Abe Sapien went to the second site, and Liz Sherman, Bud Waller, and rookie agent Sidney Leach investigated the third site.
Hellboy arrived in time to discover that Ilsa had already prepared for the resurrection ceremony, but he was distracted by an encounter with the harpy-like Women of Thessaly. Meanwhile, Rasputin’s spirit had returned, and he succeeded in transforming Ilsa into the reincarnation of the goddess Hecate, who battled with Hellboy. When Hellboy was captured and left to die chained to a pole, the revived Giurescu charged him, only to be killed in an explosion when Hellboy cracked the pole in half and struck the vampire’s horse. In fury, the iron maiden which formerly was Ilsa Haupenstein swallowed up Hellboy, trapping him within an alternate dimension.
He encountered a group of beings who claim to be Chaos itself, and told Hellboy that the time had finally come for him to embrace his purpose. His true name, “Anung Un Rama,” was revealed for the first time, and the two sawed-off horns atop Hellboy’s forehead began to regrow as a crown of fire appeared above him.
Hellboy, however, managed to overcome the transformation, telling the spirits, “screw you!” and snapping off his newly-regrown horns; an act which represents Hellboy’s devotion to the cause of good and that he truly is a well-meaning being, despite his origins or purpose. This moment of defiance instantly returned him back to our world, where he met Kate Corrigan. Backup never arrived due to an accident at the airport, and Kate revealed to a shocked Hellboy that during his adventures the other two teams had met their own misfortunes.
Liz Sherman accidentally revived a human-sized homunculus which drained her power and killed Bud Waller before fleeing. Liz felt extreme guilt over the incident. At the same time, Abe Sapien and Agent Clark had visited a church in the belief that they would meet Hellboy there due to the presence of his tracking device.
But it was revealed to be a trap set up by Rasputin, who wanted revenge against Abe for stabbing the mystic through the chest in their last encounter during the Cavendish Hall affair. Clark was killed in the process, but Abe managed to survive. The skeletal remains of Vladimir Giurescu were recovered by the B.P.R.D. while Hellboy and his fellow agents were airlifted home, exhausted by their recent mission.
Meanwhile, Rasputin's other henchmen Karl Ruprect Kroenen and Leopold Kurtz attempted to follow the will of Rasputin in castle in Norway. The two Nazi scientiests had been entrusted with the task of creating an Army for Giurescu to lead in a campaign to destroy mankind, thus bringing about Rasputin’s planned “Ragna Rok” apocalypse. However due to Kroenen's disobedience in resurrecting Nazi scientist Herman Von Klempt, whom Rasputin despised, and the accidental killing of Kurtz the undead mystic struck the C.E.O. of the Zinco Corporation, Roderick Zinco blind. While Zinco panicked, he accidentally hit a button which destroyed the fortress. However, Kurtz and Kroenen were somehow able to survive, probably thanks to Rasputin, and recently reappeared in the B.P.R.D. story Russia.

Almost Colossus

After losing her powers to the homunculus, Liz Sherman underwent treatment by Dr. Olasz at the Wauer Institute. Meanwhile, Hellboy and Kate Corrigan investigate a missing cross and several missing corpses. The culprit was the homunculus, praying for God to kill him. Instead, the homunculus met his older brother, who told him of his creator and of their plans to overthrow mankind. Hellboy and Kate discovered the homunculus' lair where they were attacked by his brother's crude homunculi henchmen. Kate was captured and the homunculus's brother planned to use her to build an enormous homunculus body for him to inhabit. Kate was rescued, but the evil brother used the giant body to attack Hellboy. The first homunculus then seemingly gave in to his brother's wishes, becoming part of the giant body. But he used the pyrokinesis taken from Liz to destroy his evil brother's new body. They rushed to the Wauer Institute and arrived just moments after Liz died. Then the homunculus, now dubbed "Roger", returned Liz's pyrokinetic powers to her, restoring her life at the cost of his own.

The Little Box of Evil

In 1999, Hellboy and Abe investigated the castle of Count Guarino after a mysterious attack. On this mission, the warlock Igor Bromhead released Ualac, a minor demon trapped in a box by St. Dunstan. Ualac was able to teach Bromhead Hellboy's secret name, Anung Un Rama, and temporarily paralyze him. Abe was shot by a chimpanzee, the former count now transformed. Ualac claimed the Crown of the Apocalypse (which sits invisibly on Hellboy's head) before attempting to take Hellboy's stone right hand. Hellboy was able to break free thanks to advice from the Daoine Sidge and killed his enemy’s mortal body. Bromhead and Ualac were claimed by the demon Astaroth, who also took Hellboy's crown down to Hell.

The Conqueror Worm Affair

This was a landmark moment in Hellboy’s multi-layered career. With the help of fellow agents Roger and Abe Sapien, among others, he faced off against an unprecedented threat: a cosmic entity bound with a Nazi scientist who had been floating through space for decades, and was now the vessel for the monstrous creature’s arrival on Earth. This beast was an alleged offspring of the Ogdru-Jahad, which the Nazis had tried to communicate with back in the 40’s. This mission to stop the ‘worm,’ now controlled by Grigori Rasputin, culminated in an intense sacrifice from Roger the Homunculus, who risked his very life to try and imprison the worm’s spirit within himself.
With assistance from the ghost of famed television-serial hero Lobster Johnson, Hellboy managed to drive away the Worm’s consciousness, and a wounded Roger was given aid by B.P.R.D. agents. Hellboy now felt deep guilt over his profession, due to him having been given by Manning prior to the mission a device to kill Roger, should he become dangerous again. Then, with a heavy heart, Hellboy announced his resignation to Kate Corrigan, before leaving to try and find out once and for all the truth behind the supposed fate that would always haunt him.

Later Adventures

2004, Africa: Hellboy sought advice from an African witch-doctor, and was told to dive to the bottom of the sea. He was captured by the Bog Roosh, who meant to prevent the Apocalypse by dismembering Hellboy and hiding the Right Hand of Doom, but Hellboy managed to escape with the assistance of a mermaid.

2006: Hellboy washed up on an unknown island. He accidentally resurrected an ancient mystic, learned the secret history of the universe, and one of the Ogdru Hem which had been reborn in the blood of a 16th century Spanish priest. This Ogdru monster was Urgo-Hem. Hellboy then set sail for England as the Daoine Sidhe watched on.

2007: Hellboy returned to England and stayed with his friend Harry Middleton, who had died years before. Rejecting the offer of Britain's witches to become their king, Hellboy was sent to another dimension to face the Baba Yaga and her warrior slave, Koshchei the Deathless.

Powers and Abilities

Half-Demon Physiology: Hellboy's superhuman abilities would seem to stem from his demonic heritage. While his specific powers and abilities have never been explicitly listed, Hellboy is much stronger and more physically durable than an ordinary human.

Superhuman Durability: Hellboy is shown to be capable of withstanding wounds that would be fatal to ordinary humans without being incapacitated, as well as recovering from injury at an incredible rate. He has been shown to withstand great impact forces, high caliber bullets, exposure to extremes of both temperature and falls from great heights. He has been savagely beaten by large monsters on several occasions and survived, often with relatively minor injuries. On one occasion, Hellboy directly charged an MG-42 machine gun and took numerous bullets to the chest before destroying the gun. On another, he was impaled by a massive spearhead through the chest, but smashed the handle and charged the attacker, leaving the spearhead buried in the tree behind him. He was also shot in the face 2 times by a double barrel shotgun, and then got up walked to the home of his shooter. He did not pass out during this.

Superhuman Strength: The extent of Hellboy's strength is unclear, but he has, for example, torn down a large tree and hurled it at an opponent. He has also thrown opponents weighing at least four to five hundred pounds. Hellboy can lift well excess of 5 tons.

Decelerated Aging: Hellboy also seems to age differently from normal Humans. At the time that young Hellboy tried his favorite food, “pamcakes” for the first time, he was technically two years old but appeared to be far older, around age six. In 1954 he already appeared to be a full grown adult, but was in reality about ten years old. His rapid physical maturation is in contrast to his physical rate of aging, which seems to be much slower than normal. Throughout the sixty year span of his life, Hellboy seems to have ceased to age ever since reaching physical maturity.

Innate Multilingualism: He also has the innate ability to comprehend ancient and magical languages.
Enhanced Sight: Hellboy has been noted to be able to see farther than the average human.

Thermal Resistance: Thanks to his demonic heritage, Hellboy's body is quite resistant against high temperatures and fire without feeling discomfort on several occasions. In the movie version, he is even more resilient against heat or burns than his comic book counterpart does, to the point became immune to all forms of fire and burns, including Liz Sherman's flames, and electrocution.

Demonic Transformation: Hellboy assumes an even more demonic form under special circumstances, either artificially or when under emotional duress. In this form, Hellboy's stumps become full-grown horns. After coming to terms with his heritage, Hellboy seems to be able transform at will, while also sprouting wings. Hellboy becomes much stronger and gains access to his latent magic. In his full-demon form, Hellboy was able to effortlessly slaughter Hell's most powerful inhabitants.

Size-Shifting: Hellboy can increase his size to the point where he's as large as Leviathan and Behemoth.

Hell-Fire Manipulation: Hellboy can unleash devastating infernos from his body.

Electrokinesis: Hellboy can call down lightning.

Flight: Hellboy can fly, though whether he uses his wings or magic to achieve this feat is unknown.

Hand-to-Hand Combatant (Basic): Although proficient with handguns, Hellboy often chooses to engage in close combat where he can utilize his incredible strength to defeat his enemies. He has also displayed skill with swords and other improvised weapons.

Occult Knowledge: His decades of experience as a paranormal investigator has given him expertise in folklore, magical rituals, the use of charms and curses, paranormal creatures and other related topics.

Personality

Hellboy is often described as a likeable, gruff person with much panache and witty humor in his attitude. He is easily angered by the (often defective) gadgets he uses, but has a genuinely good heart and love for other humans, despite his demonic origins. A living oxymoron, Hellboy is a force for good, with an iron will and a desire to do the right thing. He has continuously stated his disinterest in his supposed ‘purpose,’ and tries to hide his conflicted feelings beneath the wisecracking facade of an adventurous tough-guy who would just as soon knock back a cold beer and light a stogie, than battle demons and evil spirits.

Weapons and Equipment

In addition to his natural gifts, Hellboy carries a variety of items, such as holy relics, horseshoes, and herbs in his utility belt, as well as a variety of grenades and other demolition tools; these often come in handy when fighting supernatural beasts. He also typically carries a sidearm of some sort.
Hellboy carried a handgun given to him by a WWII era superhero named The Torch of Liberty. This gun was lost in the ocean, but was later replaced by a 1941 US Army-issue M1911A1 .45 caliber pistol provided by the ghost of Harry Middleton.
Hellboy often carries many charms and knick-knacks on his belt, which he often uses as either tools to resurrect the dead, protect him or his friends from evil entities, heal, etc. A commonly shown item among these various possessions is a Catholic Rosary.
On Hellboy’s belt is a tracking device which is constantly linked to B.P.R.D. headquarters, in order to keep track of Hellboy’s whereabouts. After the events at Hunte Castle he no longer wore this belt. (Hellboy:Conqueror Worm)
On the Giurescu mission, Hellboy used a rocket pack to make a tricky landing over the Castle. However, this “new and improved” model proved to be a wash when, upon ignition, exploded and engulfed a predictably pissed Hellboy.
Hellboy is almost always seen wearing a large and heavy jacket that reaches well below his knees. The pockets of this jacket are typically filled with many of the charms and totems mentioned above, granting him even greater paranormal protection. His original jacket bore the B.P.R.D. logo on its sleeve, but after he quit the Bureau this logo vanished, indicating that he either removed it or the jacket he is currently wearing is a new one altogether. His jacket has been heavily damaged many times, yet it always shows up repaired with each new story, indicating that Hellboy might have some skill in weaving.
Hellboy briefly wielded the sword Excalibur, from Arthurian Legend. Supposedly, wielding this sword marks him as the rightful King of England, and will allow him to lead an army of England's noble dead.
In the movies Hellboy is also equipped with a large pistol, the Good Samaritan, which uses specially modified bullets to combat supernatural beings. It often runs out of ammo, and is prone to jamming.

Origins and Destiny

Hellboy's destiny has been a common and persistent theme in the series, and becomes more and more complicated with every story arc. The first thing we knew about Hellboy was that he was destined to be the Beast of the Apocalypse. Bearing the Right Hand of Doom, which came from one of the Watchers who made the Ogdru Jahad, Hellboy possesses the one thing capable of waking the terrible beasts from their prison and unleashing them to end the days of man. For a long time, this has been the main focus of his destiny, and the thing he has constantly avoided.
During the Wild Hunt story arc, however, his destiny took another interesting turn. It had already been revealed that Hellboy is the son of Azzael, a major demon, and Sarah Hughes, a witch who spent most of her life in repentance after summoning him. Sarah had two human children besides Hellboy, a nun and a pastor, both of whom died a swift death trying to protect their mother from Azzael in the hopes of breaking his claim over her. Azzael would not be denied, he hooked his chains into the body of Sarah Hughes and dragged her down to Hell.
Sarah Hughes is a descendant of the traitor Sir Mordred, who died while slaying King Arthur. Mordred himself was the bastard son of King Arthur and Morgana Le Fay, who was Arthur's sister. Mordred had three sons, who were all executed, and a daughter who was hidden away. Through this daughter, Mordred's bloodline continued up to Sarah, her human children, and Hellboy himself. This makes Hellboy a descendant of King Arthur, and thus, the lawful King of England. Through this, it has been said that he was destined to wear a crown all along, be it in Hell or on Earth, and that his destiny as Arthur's descendant is to pull the sword Excalibur from the stone, and lead Britain's army of the dead - another part of Hellboy's destiny of which he doesn't seem too sure about.

Allies

Abraham Sapien: An amphibious humanoid of mysterious origin, this fellow agent can breathe underwater thanks to a set of gills. Hellboy first sympathized with Abe and saved him from dissection by the B.P.R.D. scientists, the two became best friends with a brother relationship. In field work Abe was first like a sidekick to Hellboy until becoming an equal in the Bureau.

Elizabeth Sherman: A pyrokinetic, brooding, somber woman has the psychic ability to create and manipulate fire. However, she suffers from guilt and a lack of self-confidence over her unstable and often downright dangerous ability. When she was a child, she accidentally killed her parents with her powers, and has since always been haunted by her failures and mistakes. In the 2004 film, she is portrayed as as having a romantic relationship with Hellboy and is pregnant with his twin children. However, their relationship in the comics is simply that of good friends.

Roger: An abnormally large, artificial man created from blood and herbs mixed in a jar with horse manure. Roger was discovered by Liz Sherman’s party during the Guirescu Affair, and was accidentally revived inside the secret laboratory he was built in by Sherman, who had curiously reached into a hole in his chest. Her fiery abilities sparked the creature to life, and the startled, frightened and confused homunculus lashed out and killed Agent Waller. However, at a later time the creature, to be named Roger eventually, was confronted by Hellboy and the beast helped revive a seriously injured Liz Sherman. Roger was rewarded with Agent status, and became a close partner of Hellboy during the Conqueror Worm mission.

Trevor Bruttenholm: Hellboy’s mentor and adoptive father. Pronounced “Broom,” the Professor was killed by a plague of frogs summoned by Grigori Rasputin, as a way to entice Hellboy into investigating the strange murder and falling right into the deranged mystic’s plans.
Thomas Manning: The head of the B.P.R.D. and Hellboy’s boss. He is the one who usually briefs Hellboy and his fellow agents on their new missions.

Kate Corrigan: One of Hellboy’s most beloved teammates, Kate is an expert agent and motherly figure of the B.P.R.D. She is often on hand to give support and strong-willed advice, as well as criticism. An expert of the occult, Kate is a very dear friend and partner of Hellboy.
Johann Kraus: A German medium who was displaced from his body, although his body was destroyed his ectoplasmic form remained.

Angel the Vampire (apocryphal): In the Angel/Buffy comic The City of Despair, Hellboy and a Predator make cameos as gladiators in another dimension where Buffy and Angel have to fight each other in the end. Hellboy also makes appearances in two other Angel comics: Past Lives, The Book of Carthage.

Enemies

Grigori Rasputin: The former infamous "Mad Monk" of Tsarist Russia, he is now an undead mystic who claims to be the official messenger of the terrible cosmic entity, the Ogdru Jahad, and is completely devoted to bringing about the end of days, by any means. He was under the employ of the Nazis in the mid-forties when he summoned Hellboy to Earth, intending him to be the leader of Rasputin’s forces in the coming apocalypse. He and his ‘creation’ first met during the Cavendish mission, and has since been manipulating numerous events, to further his motives. He had a romantic relationship with Ilsa Haupenstein. He is considered to be Hellboy's archenemy.

Herman von Klempt: A deranged Nazi scientist who is in fact a disembodied head which is kept alive inside a jar of liquid. His gruesome experiments with helpless village girls introduced him to Hellboy, who would become his greatest adversary in his twisted plans. Under his control is an army of gigantic gorillas, controlled through a mental device implanted within the ape's brains. They do the brunt of Von Klempt’s work, and are in fact slightly sympathetic creatures, due to their mindless control under the mad Von Klempt.

The Baba Yaga: This powerful and ancient witch, who resides in a chicken-legged house, has been on this Earth for centuries, and has a personal hatred for Hellboy after he shot out her left eye. Rasputin refers to Baba Yaga as his grandmother, and she has a tender, maternal relationship with the mystic.

Ilsa Haupstein: This Nazi woman was a deeply loyal follower of Grigori Rasputin, and had a romantic attraction to him. Seduced into believing Rasputin’s prophecy of the Ogrdu Jahad’s complete destruction of Earth and rebirth as a beautiful paradise free of conflict or moral sins, she was convinced to enter a metal torture device, which transformed Ilsa into the malevolent goddess Hecate. This evil entity swallowed up Hellboy, transporting him to an eerie realm where he confronted his purpose and experienced the re-growth of his horns.

Hecate: Hellboy first encounters the witch goddess Hecate after defeating Vladimir Giurescu for the first time. Hecate informs Hellboy that they are tied to the apocalypse and that they will either die together or live through it together to see the new world. Hellboy defeats Hecate, but she lives on in an iron body fueled by the blood and bones of Ilsa Haupstein.
