[[caption-width-right:350:The original team, from left to right: Johann Kraus, Liz Sherman, Abe Sapien, Roger, Kate Corrigan.]]
A spinoff series of comics set in the ''ComicBook/{{Hellboy}}'' universe, which picks up after Hellboy leaves the titular [[WhoYouGonnaCall Bureau for Paranormal Research and Defense]]. The series follows the remaining agents as they continue trying to prevent TheEndOfTheWorldAsWeKnowIt, fighting the rapidly multiplying frogmen and confronting several particularly nasty villains. Long story short, [[HolyShitQuotient it's not working]].

It's written by Mike Mignola working together with John Arcudi, and at first illustrated by Guy Davis, whose artwork sets a different tone from the original series. Beginning in 2011, the series was rebranded as ''BPRD: Hell On Earth''. Davis left shortly after, and was replaced by a number of artists, Tyler Crook and James Harren being the most prevalent.

!!Provides Examples Of:

* ADayInTheLimelight: Several miniseries focus on the adventures of regular BPRD field agents--the [[RedShirt redshirts]] of ''Hellboy''. [[MauveShirt Agent Giarocco]] has been prevalent in two series now. [[spoiler:This becomes increasingly common as the organization begins to lose the superpowered agents in one way or another.]]
* AlternateContinuity: Averted. It's still occurring along the same timeline as ComicBook/{{Hellboy}}, but despite the scale of events in both series, they virtually never overlap.
* AmplifierArtifact: [[spoiler: the strange plug-thing Liz uses on the mountain-sized Ogdru Hem]]
* ApocalypseHow:
** [[spoiler:By ''King of Fear'', Regional Class 1s are occurring all over the world. Munich is destroyed by ancient Hyperborean robots, Nebraska gets ravaged by Katha-Hem, Houston is obliterated by a supervolcano, a gigantic crustacean creature is sitting in the Salton Sea and breathing toxic vapors into the atmosphere, and half the Indonesian archipelago's just ''disappeared''. England is also devastated by Hellboy's battle against the Ogdru Jahad.]]
** [[spoiler:And as of ''The Return of the Master'' the ante is upped further with an earthquake that is seemingly felt ''everywhere on Earth'', resulting in dozens of Ogdru Hem popping up all over the world, from New York to Vladivostok. As if that weren't bad enough, the Salton Sea monster has finally started moving, and it's leaving behind ''eggs'']].
* ApocalypseMaiden: In ''King of Fear''', it's been revealed [[spoiler:that Abe will also have a role in the [[TheEndOfTheWorldAsWeKnowIt end of the world]]]].
* ArtificialHuman: Roger the Homunculus.
* Ascended Extra: Agent Devon goes from being a MauveShirt to a vital member of the central team.
* AstralProjection: Johann Kraus.
* BackFromTheDead:
** [[spoiler:Subverted with Roger. They even spend an entire story arc letting you think it's gonna happen.]]
** [[spoiler:More or less the plot of ''Return of the Master''. Hellboy's BigBad Rasputin seems to have finally, successfully been resurrected. As he is repelling an attack from the BPRD, Zinco Corporation, unaware Rasputin is alive, try to resurrect him themselves, but inadvertently bring back the Black Flame instead. The ensuing worldwide chaos destroys the real Rasputin's fortress, leaving his fate ambiguous.]]
** [[spoiler: Karl Ruprecht Kroenen and Leopold Kurtz, the Nazi scientists who died in ''Wake the Devil'', have somehow been brought back to life and are working for Mr. Marsten, Pope's successor as CEO of Zinco, in the latest arcs of ''Hell on Earth''. In their effort to bring back Rasputin, they inadvertently brought back the Black Flame and caused even further global destruction.]]
* BadassBookworm: Kate Corrigan.
* BadassNormal: Many of the BPRD agents, especially Carla Giarocco.
* TheBeastmaster: Panya can telepathically control non-sentient creatures. This also includes humans who are severely mentally disabled.
* TheBerserker: Agent Howards, after being awoken from his coma, forgoes the BPRD's armor and firearms, and runs screaming into battle with nothing but a broken Hyperborean sword. [[BadassAbnormal He is devastatingly effective]].
* BigBad: The Black Flame, Memnan Saa.
* BiggerBad: The Ogdru Jahad.
* TheBlank: Johann, due to his lack of a physical form.
* BloodierAndGorier: Moreso than Hellboy, for sure. Guy Davis doesn't make much use of [[GoryDiscretionShot gory discretion shots]]. ''Killing Ground'' is especially violent.
* CaptainErsatz: Mr. Pope is a pretty blatant parody of [[{{WesternAnimation/Gargoyles}} David Xanatos]].
* {{Chiaroscuro}}: When Mignola's doing the art it borders on tenebrism.
* ClueFromEd: Used very sparsely, generally to point you out which prior stories a referenced event occurred in. They are not attributed to an editor.
* ComicBookTime:
** The only major character who's aged visibly in the nearly two decades since the comic began is Tom Manning, and that may just be due to Guy Davis' different art style.
** Kate Corrigan also seems to be aging. Guy Davis' art makes Liz look reasonably older, but her birth date's 1962.
** This was mentioned by a fan in a letter to the editor, who responded with [[HandWave "They look pretty good for their ages, but they're pseudomilitary. They work out."]]
* CosmicHorrorStory / LovecraftLite: Although the "Lite" is becoming debatable, especially with the ''Hell on Earth'' arc.
* CrazySurvivalist: [[spoiler:Daimio, as he appears in ''New World''.]]
* CrossoverCosmology: Deities and monsters of classical mythology make regular appearances, while {{God}} was responsible for the creation of the (originally non-evil) lovecraft elements mentioned above.
* CrystalPrison: The Ogru'Jahad's prison.
* CursedWithAwesome: Liz Sherman.
* DarkMessiah: this is how Memnan Saa sees himself.
* ADayInTheLimelight:
** The "War on Frogs" miniseries could count for several agents.
** "Garden of Souls" is almost completely devoted to Abe Sapien with some supporting action for Daimio.
* DemonSlaying
* DemonicPossession: [[spoiler: Plays a major part in Daimio's backstory.]]
* DeusExNukina: In ''1948'', the BPRD is sent to investigate the appearance of bizarre monsters immediately after a nuclear test. [[spoiler:It's hinted that the nuke somehow opened a portal to an alternate Earth and let the creatures through.]]
* DullSurprise: Liz Sherman's default expression for most of the comics. Justified, as she's supposed to be depressed and heavily medicated due to her [[DarkAndTroubledPast tragic past]], and in the later ''BPRD'' series, she gets better.
* EldritchAbomination: Ogdru Jahad and their 369 offspring Ogdru Hem, which are Sadu-Hem and Katha-Hem, among others. Creator/HPLovecraft's influence here is no surprise.
* EvilSorcerer: Memnan Saa.
* ExtranormalInstitute: The BRPD's offices.
* FantasyKitchenSink: The size of an Olympic swimming pool.
* FetusTerrible: [[spoiler:Mrs. Kihnl's babies in ''New World'', revealed to be more Ogdru Hem.]]
* FishPeople: Abe Sapien.
* {{Geek}}: Kate Corrigan was the occult/mythology geek in the comics (it was her day job before she joined the BPRD). Recently, Johann Krauss seems to be turning into the evil version of this.
* GoodScarsEvilScars: 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. [[spoiler: Blame the jaguar demon that's now [[DemonicPossession inhabiting his soul.]]]]
* GratuitousGerman: Johann Krauss, when he loses his temper. Allmachtiger!
* {{Grimmification}}
* TheHedonist: Johann in ''Killing Ground'', when he (temporarily) finds a new body, 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.
* HeWhoFightsMonsters: Agent Simon Anders' fate in ''BPRD: Vampire''.
* HoistByHisOwnPetard: [[spoiler:Thanks to the vampiric Brezina sisters, Simon Anders has now become a super-vampire determined to wipe out all other vampires from the face of the earth. Even the vampire lords are ''terrified''. ]]
* HollowWorld: The miniseries ''Hollow Earth''.
* HumongousMecha: The Hyperborean war machines.
* InitialismTitle
* {{Kaiju}}: Many of the Ogdru Hem are such, skyscraper-sized or larger, burrowing up through the ground and crawling from the ocean to lay waste to many major cities.
* KillItWithFire: Liz uses this a lot, obviously. Also, the BPRD usually sends one "flame-thrower guy" with field teams when they expect contact. Most of the abominations can be killed with fire, though not all.
* LevitatingLotusPosition: Liz talks to a Shangri La monk while he's in the LotusPosition three feet off the ground.
* LoveTriangle: A damn weird one in Johann Krauss' past. He fell in love with the ghost of a man's wife he was hired to contact as a spirit medium. Naturally, this did not end well.
* MaskedLuchador: Lobster Johnson (see ShowWithinAShow, below).
* MightyWhitey: Invoked, but ultimately subverted by Martin "Fu Manchu" Gilfryd.
* AMillionIsAStatistic: Used and inverted by the protagonists and the antagonists in "The Black Goddess."
* MysteriousPast: Oh, yeah. The exact amount of mystery varies between characters. Several have even gotten enough plot attention to not be mysterious anymore.
* MundaneUtility: Liz Sherman lighting her cigarettes with pyrokinesis.
* ObstructiveBureaucrat: Agent Devon seems to be turning into one.
* OurMonstersAreWeird: Frequently, especially the hybrid animals in ''Garden of Souls''.
* OurVampiresAreDifferent: Given the nature of the series, this is to be expected. In ''1946'', Bruttenholm and his team have to deal with Vampire-Human hybrids made from injecting the mentally and physically disabled, gay, and other prisoners that the Nazis had rounded up with vampire blood.
** [[spoiler:The leading vampires have concocted a plan for taking over the world, which basically amounts to vampires hiding themselves long enough for mankind to forget how to fight them.]]
* PutOnABus: What the series did to Hellboy. This also happens to Abe in an awesome way in ''The Dead''.
* RedShirt: Just about any regular BPRD agent who has the gall to tag along with the main characters on their missions isn't coming back.
** Certain agents may be {{MauveShirt}}s, however, with Agent Devon being one of the more notable examples.
** RedshirtArmy ([[InvokedTrope Invoking]] FacelessGoons as well).
* ShellShockedSenior: Captain Ben Daimio. [[spoiler:He was dead for three days, wouldn't you be too?]]
* ShowWithinAShow: After his death in 1939, [[TwoFistedTales two-fisted]] adventure hero The Lobster became the subject of a number of these: PulpMagazine stories, [[ComicBookAdaptation comic books]], {{Film Serial}}s, and finally Mexican movies with The Lobster (or, rather, "Lobster Johnson," the last name taken from the SecretIdentity he was given in the pulps) as a MaskedLuchador. Compared to his RealLife, they all make for ''massive'' cases of AdaptationDecay, and [[StylisticSuck are all considered atrociously terrible]], although some people (including Hellboy himself) [[CultClassic enjoy them anyway]]. The existence of these adaptations allow the ''Hellboy''-verse's US government to cover up the existence of the real Lobster (and the fact that he was a spy for them in WWII), and as a further side-effect, the character is more readily known, on both sides of the FourthWall, as "Lobster Johnson."
* SilentSceneryPanel: Lots of close-ups of thematically-important artwork and statuary.
* SixthRanger: While sorting the various agents into roles is a bit tricky, Captain Daimio seems to be a SixthRanger. Johann may also qualify.
* SoleSurvivingScientist: When the Bureau gets its new headquarters, a disaffected nuclear-proof bunker in the mountains, they find an old scientist whose been living there since its was shut down, writing down notes on a typewriter for so long the keys wore out and it punched holes in the paper, he was so far gone he didn't notice. [[spoiler: He later releases an EldritchAbomination into the base thinking it some kind of angelic creature.]]
* {{Spinoff}}
* SteamPunk: The robots [[spoiler:encasing Langdon Everett Caul's former colleagues]] in ''Garden of Souls''.
* StylisticSuck: See ShowWithinAShow, above.
* SuperpoweredEvilSide: [[spoiler:Daimio has one, thanks to the aforementioned DemonicPossession. In ''Killing Ground'', it wakes up.]]
* TheTeamNormal: Kate Corrigan.
* TechnologyPorn: One word: [[spoiler:Helicarrier]].
* TheUnmasquedWorld: Especially as the series continues, and any semblance of secrecy was torn to shreds in ''The Black Flame'', [[spoiler:in which a mountain-sized EldritchAbomination rampages through the central United States and crushes several cities to rubble.]]
* UrbanLegend: Lobster Johnson, and this is the main reason why all the [[ShowWithinAShow in-universe stories]] about him are [[StylisticSuck pulpy]] and wildly incorrect.
* VillainsNeverLie: During his efforts to win Liz's trust, Memnan Saa points out that nothing he has told her before was untrue.
* VillainTeamUp: See main article for details.
* TheVirus: One of the more horrific, and common, fates in the series is being transformed into horrible demon-spawn frog monsters. No race, gender or age group is spared. It gets upgraded in ''King of Fear'': [[spoiler:The Frogmen are being replaced by hideous four-legged crablike "hammerheads", and the infecting agent is now [[OhCrap airborne]]]].
* WellIntentionedExtremist: 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''?
* WreathedInFlames: Liz can do this.
* WhamLine: Near the end of ''Hell on Earth: Return of the Master''.
-->'''Leopold''': What is happening?!
-->[[spoiler:'''The Black Flame''']]: ''Everything''.
* WhatMeasureIsANonHuman:
** The BPRD comes down on the wrong side of this question when it [[spoiler:fits Roger the Homunculus with a self-destruct]].
** And this comes up in ''The Black Goddess'' a bit with Johann.
* ZorroMark: Lobster Johnson's lobster claw.
* ZombieApocalypse: Large swaths of the American countryside are under the effect of an Ogdru Hem's toxic vapor, which turns people into mutant undead. ''No One's Safe in the Wasteland'', where Johann's team has to cross rural Illinois on foot, almost feels like an issue of ''ComicBook/TheWalkingDead''.
