The leader of the Grail.
- Adaptational Jerkass: In the comic, while he was interested in the Word and had the same apocalyptic ambitions via the inbred descendant of Jesus Christ, he was mainly interested in Jesse because he had killed his aunt, Marie L'Angelle. In the show, because the Grail and Angelville storylines happen concurrently, the Allfather's relation to L'Angelle was Adapted Out, removing any excuse of Even Evil Has Loved Ones. He takes interest in Jesse not only because he poses a threat to the Grail's agenda, but he wants to have Genesis for Humperdoo's use, and he's willing to kill multiple Humperdoo clones to eventually make it compatible.
- Adipose Rex: He's the leader of the Grail, and he's so fat that he needs assistance moving.
- All There in the Manual: He is only ever referred to as Allfather in the show. His actual name comes from the comic.
- Ass Kicks You: Starr relates to Jesse how The Allfather once killed a subordinate by sitting on his head, splattering it like a rotten melon.
- Bad Boss: He makes Herr Starr look reasonable by comparison. He had his gastroenterologist beheaded for his stomach staples not holding. And considering that execution is a common punishment among the Grail, beheading is one of the more merciful punishments the Allfather has inflicted.
- Big-Bad Ensemble: In season 3 with Marie L'Angelle, Eccarius and Satan.
- Cruel and Unusual Death: Execution is one of (if not the) most common punishment in the Grail for failure, so the question is not if the Allfather is going to kill you, but how horribly. Not only does Herr Starr assume he's going to be Flayed Alive for Humperdoo only being good at tap-dancing, he remembers the Allfather executing a follower by crushing his skull under his ass for the mundane crime of touching his hotpocket.
- The Dreaded: Herr Starr fears what he will do to him if Humperdoo doesn't live up to the expectations of the Messiah and what would happen if he found out he was plotting a coup and trying to groom a more mentally competent Messiah that wasn't genetically related to Jesus Christ. Thankfully, Humperdoo's tap-dancing skills are enough to satisfy the Allfather.
- Fat Bastard: His obesity is comparable to Mr. Creosote, and he's a very evil man. He's well aware enough of his own body weight that he once executed a follower by sitting on his head.
- Jabba Table Manners: When he's introduced eating an entire table's worth of food, he's also shown to be a very messy eater. After eating an entire horse with Starr, he's also shown to be bulimic.
- Karmic Death: He wanted to take Genesis for his use, but knowing that Genesis is dangerously picky about hosts, he had no intention of being its bearer. Instead, he planned to have it used by the eugenically-inbred descendant of Jesus Christ, whom the Allfather sees as little more than a useful idiot for the Grail's agenda. He also had no problem killing multiple Humperdoo clones to make that possible. Jesse does in him by forcing him to absorb Genesis, with predictable results.
- Kevlard: He survives multiple gunshot wounds from Jesse Custer to the chest thanks to his many, many layers of fat.
- Ludicrous Gibs: Jesse kills him by having the Genesis-sucking machine transfer Genesis to the Allfather instead of a Tom/Brady-infused Humperdoo, causing the Allfather to explode messily.
- Oh, Crap!: He understandably freaks out when Jesse forces him to absorb Genesis, knowing very well he's unworthy of its power, and what's going to happen next.
- Omnicidal Maniac: He is actively plotting for Armageddon to happen, because he believes that it will decide who is worthy of God's grace.
- Stout Strength: Of a sort. He may not be strong in the traditional sense, but he's well-versed in leveraging his 700 lb. bulk to win fights. He easily disarms Jesse in their confrontation and immediately throws his full weight onto him, counting on his sheer mass to either crush or asphyxiate him.
- Villainous Glutton: He's usually seen with mountains of food around him.
Dr. Louis Slotnick
The lead scientist of the Grail.
A former Italian mob boss from Bensonhurst, Brooklyn, who was hired by Herr Starr as a guest lecturer for the Grail's "Advanced Torture" class.
- Arc Villain: He serves as one for Cassidy during his imprisonment in Masada. Cassidy doesn't strike back at Frankie until after he gains the resolve to escape and rejoin Jesse and Tulip.
- Cruel and Unusual Death: After Cassidy develops the resolve to escape from Masada and frees himself using one of the Archangel's feathers, he shoves a shotgun up Tony's anus, then firing it off-screen. The end result is an exploded brain and the top of his skull missing.
- Groin Attack: His choice for torturing Cassidy is to abuse his Healing Factor and harvest his foreskins for a variety of purposes, such as making skin cream making a replacement ear for Herr Starr.
- Karmic Death: The Torture Technician dies a torturous death at the hands of a man he tortured.
- Torture Technician: He was once one for the Italian mob, and he uses his experience during his employment with the Grail.
The direct descendant of Jesus Christ who is supposed to usher in a new golden age for humanity... That being said, 2,000 years of inbreeding have left him with some very unfortunate genetic complications.
- The Anti-Christ: Despite his title as the Messiah, bringing about the end of humanity as we know it was Gods real plan for him.
- Cloning Blues: The Grail has seemingly thousands of clones of him, all created as redundancies in case something goes wrong. The real one is kept separate so as not to confuse the "true" Messiah, and the rest are considered entirely expendable. Jesse confuses the matter by dressing the "real" messiah as one of the clones and releasing them all into the wild.
- Friend to All Living Things: When Cassidy and Tulip find him after he has wandered off, they see Humperdoo interacting with a deer, who is completely at ease while Humperdoo caresses its neck. Wild animals, as well as most humans, are naturally drawn to him, hinting at his totally gentle, if not divine, nature.
- Hidden Depths: Despite his challenges he's actually a fantastic tap dancer! As shown by his drawings of the Man-Dog when Jesse first met him, he apparently has some connection with God.
- It's implied that he knows perfectly well what the rocket ship really means, and accepts it with a smile.
- He also finds God terrifying, which makes him the Only Sane Man in the Grail.
- Identical Grandson: He actually looks almost exactly like Jesus (they're both played by the same actor), but his features are off. He has crossed eyes, horrible buck teeth, and sunken cheeks.
- Incorruptible Pure Pureness: The nicest character in the series. Cassidy notes that he was nice to everyone while grieving for him.
- Inspirationally Disadvantaged: He's supposed to be this, what with being Christ's descendant and all, and a worthy vessel for Genesis. But no, he's really just an inbred moron.
- Nice Guy: Shy, but friendly. Too friendly. If he likes you, he'll first piss on you then jack off against your leg. If he does it long enough he'll "discharge."
- Reality Ensues: When it was discovered that Jesus Christ fathered a child, it was decided to keep the lineage as pure as possible with zero compromise. Naturally, the latest descendant suffers from severe mental and physical disabilities.
- Shoot the Dog: His fate, being shot by a remorseful Cassidy so he can't kickstart the end of the world.
- Spared by the Adaptation: In the comic, his source character, Humperdido, was crushed to death by the Allfather being dropped on him (the Allfather also getting killed in the process). In the show, the Allfather is killed by Genesis, and while Humperdoo had many clones die, the original Humperdoo is released from the Grail's captivity, hiding among his clones. He later Dies Differently in Adaptation.
- Toilet Humor: Pees on Jesse Custer upon meeting him. He does this to everyone he likes.
- Too Good for This Sinful Earth: Accepts death at Cassidy's hands rather than be God's pawn.
- Unwitting Pawn: He's really nothing more than an unwitting receptacle for D'Aronique to rule the world. However, his utter lack of anything resembling intelligence makes even that very difficult. It's next to impossible to train him to appear as a commanding figure.
Klaus Helmut Starr
As a high-ranking member of the Grail, a powerful, super-secret organization, Starr is a gifted mastermind and is always one step ahead of his prey. When he learns of Jesse Custer and his mysterious power, Herr Starr puts his own master plan into action.
- Adaptational Badass: The comic book version was a cunning tactician and excellent marksman, but without hope in a physical fight. In the show, he's an at least average fighter and a Combat Pragmatist.
- Adaptational Jerkass: Comic Starr was far from a nice guy, but it took him years before he got to the point of killing off Grail personnel.
- Adaptational Wimp: In contrast to the Adaptational Badass entry above, Starr takes his repeated humiliation and continuing disfigurement with much less grace than the comics version. He even has to be rescued by the cannibals and is broken to the point of weeping, later trying to commit suicide. The comics version freed himself and hopped through the entire desert on his remaining leg.
- Bad Boss: He constantly insults and belittles his employees and can't even be bothered to read their reports. Oh, and he summarily executes them if they fail in a mission. Or if they just bump into him.
- Bald of Evil: A completely bald villain.
- Big Bad Duumvirate: Takes center stage in Season 4 again, this time with the help of God himself, to get revenge against Jesse.
- Big-Bad Ensemble: With Superintendent Mannering and the Saint of Killers in Season 2. And despite not being the most powerful out of the three, his plans drive most of the Season.
- Bondage Is Bad: His extremely kinky sexual tastes are played for grotesque horror and disgust.
- Brains and Bondage: Highly intelligent, coldly cerebral, and extremely kinky.
- Butt-Monkey: Starting from Season 3, Starr suffers a string of disfiguring injuries and humiliations. First, Tulip gives him a scar across his scalp that makes his head look like a penis, inviting comments on it from anyone that isn't subservient to him (those that are don't comment on it for obvious reasons). He's also under the threat of the Allfather executing him for either Humperdoo's inadequacies or plotting a coup. After Jesse gets his soul back, not only are the Grail's plans involving the Messiah ruined, he is forbidden from wearing hats again. Season 4 starts with with him losing his right ear to Jesse's machinations, then having his replacement ear crudely made from parts of Cassidy's harvested foreskins, which also falls off just after being told how beautiful he is. After admitting to God that he lost Humperdoo, he gets his genitals bitten off by a dingo. Later, a group of cannibals give him a faucet to replace his lost genitals, chop off his leg and feeds him it. Having enough suffering, he attempts to hang himself, only to fail and have his nipples torn off. His suffering ends when God restores him to his former glory after he retrieves Humperdoo.
- Colonel Badass: Holds the rank of lieutenant colonel in the GSG9.
- Combat Pragmatist: Distracts a combat instructor during training by masturbating while in a chokehold, delivers a kick to the crotch, and then returns a few moments later with a piece of metal to bludgeon the incapacitated instructor to death. In the series finale, he confuses the two cops looking for him the same way, then snatching their gun and killing them.
- Cutting the Knot: When it is down to him and another candidate in a pistol shooting competition, rather than outperform the other candidate impressive skills, he simply shoots him dead.
- Deadpan Snarker: He will not hesitate to make mocking jokes about anyone or anything he finds worthy of mockery. And he delivers that utterly deadpan since, well, he says everything almost completely without emotion.
- "Like a 10-inch dick, I need to see it to believe it."
- Disabled in the Adaptation: Zigzagged. Starr suffers the exact same humiliating injuries he did in the comic (and he got an additional injury in the form of accidentally tearing his nipples off in a bungled suicide attempt). However, God eventually restores him after retrieving Humperdoo, and he remains intact until the very end.
- Dragon Ascendant: Seems to have taken over the Grail after the Allfather's gory demise.
- Dragon-in-Chief: He was one of the biggest threats towards the main characters throughout Seasons 2 and 3, but he was doing so under the Allfather's orders.
- Dragon Their Feet: After killing the Allfather, he and Jesse try to fight over the vial containing the latter's soul.
- Dragon with an Agenda: He has his own plans for what to do with Genesis.
- Ear Ache: He loses his right ear in "Masada" during a fire fight between his followers after Jesse had used Genesis on one of them. He's given a new one made from parts of Cassidy's severed genitals.
- Early-Bird Cameo: He's seen very briefly from behind in the first season, before being properly added to the cast for Season 2.
- Elites Are More Glamorous: Is a member of the vaunted German police special forces unit GSG9
- Europeans Are Kinky: Meets with the Grail initially for the promise of access to a brothel, and wears a nipple chain.
- Even Evil Has Standards: As much of a sociopath and prone to killing as he is, he is horrified to learn that the Allfather is eager for a nuclear Armageddon. Herr Starr wants to rule the world, not destroy it.
- Eyepatch of Power: He doesn't bother with one, showing off his right milky-white eye openly.
- Eye Scream: His right eye was damaged when the losers of a youth singing contest cut it with a knife in retaliation for him winning.
- Fashionable Asymmetry: His right eye is white, with a scar across it.
- Groin Attack: After Starr is forced to admit that Humperdoo is missing, God compels a dingo to rip off Starr's junk. It temporarily gets replaced with a faucet before God restores his body as a reward for reclaiming Humperdoo.
- Hero Killer: His job is to kill off anyone who starts looking too much like The Messiah since the Grail doesn't want competition for the one they're planning to introduce. However, he realizes the Messiah they have been raising for two-thousand years is a mentally-impaired inbred and that the world at large wouldn't accept him, so he's actually trying to get Jesse to be the new Messiah under the Allfather's nose.
- I Just Want to Be Beautiful: In Season 4, it's revealed that he just wants to achieve beauty. However, in a cruel a bit of irony, he keeps getting horribly disfigured, and certain factors make it really difficult to hide said disfigurations. Some of this stems from him losing his eye just for winning a youth singing contest. It gets to the point that once he suffers so many injuries that he sees himself as a freak, he tries to commit suicide. However, he does get his beauty restored after retrieving Humperdoo from Tulip and Cassidy.
- Karma Houdini: He makes it out of the series completely unscathed, retiring somewhere and playing golf, presumably for the rest of his life. He even kills the police officers who were tracking him and the Grail for at least two years when they come to make their move on him.
- Man in White: Like other Grail operatives, he wears a pristine white suit when working.
- Motive Decay: Just like in the comics, after suffering a string of humiliation from Jesse, he stops trying to convince him to be the Grail's messiah and plans to get plain old revenge.
- Murder Is the Best Solution: His seduction and marksmanship tests are completed with threats of murder and murder respectively, he gives himself a Klingon Promotion immediately upon joining the Grail, he gets rid of the fledgling floating-pig cult in "Pig" by killing not only the pig but everyone who lived in the same village as it... All in all, it seems he believes strongly in this trope.
- Named by the Adaptation: Was simply "Herr Starr" in the comics.
- Nice Hat: Wears one, as part of his Grail uniform. After getting scarred across his scalp by Tulip, he's almost always wearing a hat of some kind in public, partially because the scar makes his head look like the tip of a penis. After Jesse gets his soul (and full command of Genesis) back, Starr is commanded to not wear hats anymore, forcing him to endure the humiliation of wearing an ill-fitting wig or going around with a phallic head.
- No Social Skills: Or rather, he does not seem to care about social skills in the least. He is usually extremely blunt and unsubtle in his social interactions. When Starr negotiates, he openly uses threats and bribes without any attempts to make himself seem likable. The only times he actually is tactful and polite is towards people he fears.
- Only Sane Man: Like his comic counterpart, he seems to be the only one in the upper echelons of the Grail who is not blinded by religious devotion and realizes what a joke the inbred idiot descendant of Christ is.
- Politically Incorrect Villain: While his comic counterpart was supremely open-minded about these things, this version of Herr Starr sees nothing strange in a video of Jesse using his Compelling Voice on Tulip - because why shouldn't a woman do whatever a man tells her to? His misogyny also causes him to underestimate Dr. Slotnick's talents until she perfects a genetic cocktail that could allow anyone to accept Genesis without exploding.
- Retired Monster: His ultimate fate after leaving the Grail.
- Spared by the Adaptation: Unlike his comic book counterpart, he survives the events of the series.
- Surrounded by Idiots: His default reaction towards his subordinates.
- The Starscream: He is this to Allfather D'Aronique, claiming that he is behind the Allfather's plan to have Humperdoo be the Messiah when he's secretly trying to install Jesse. He has even more reason to plot a coup when he learns that the Allfather is an Omnicidal Maniac.
- Too Kinky to Torture: While others scream and pass out from the pain, Starr seems to enjoy having his privates shocked by a car battery. Also invoked in how he passes the hand-to-hand test. It takes getting his privates bitten off by a dingo and having his own leg fed to him by cannibals to finally break him.
- Visual Pun: In Season 3, Tulip gives him a scar that makes his head look like a penis. In other words, he's a dickhead.
- You Are in Command Now: Becomes the new Allfather of the Grail after D'Aronique's death.
One of the Grails best operatives, Featherstone reports to Herr Starr. Shes smart, calculating and isnt afraid to use any means, including her sexuality, to complete her assigned mission. Featherstone has committed her life to the Grail and will stop at nothing to protect their objectives.
- Adaptational Badass: In the comics, she was smart and efficient, but very much a regular person. In the series, she's a Master of Disguise who can face near-certain death without batting an eyelid and has proven herself able to beat Tulip in a fight. With a handgun against an improvised weapon, true, but Tulip has beaten worse odds.
- Adaptational Jerkass: In the comics, she was technically a villain, but pretty thoroughly sympathetic and ultimately more misguided than anything else. In the series, she's fanatical, ice-cold and with signs of a bloodthirsty, vengeful streak.
- Arch-Enemy: She and Tulip become really personal enemies, especially after Featherstone kills her and Tulip later suckerpunches her in return and almost gives her to the Angel of Death.
- Beauty Is Never Tarnished: Averted. She gets a broken nose from Tulip in Season 3.
- Boom, Headshot!: How she meets her end at the hands of Herr Starr.
- Broken Bird: Her "Jenny" persona is timid, eager to please and lives in fear of her abusive ex-boyfriend.
- Broken Pedestal: Herr Starr, after she finds out that he was never a believer and only joined the Grail for joy and power.
- The Chanteuse: Her "Lara" persona is sexy, aloof and melancholic, has inadvertently gotten involved with something dangerous, and sings in a bar for a living.
- Child Hater: While she acts out the "loving single mother" part of her cover very convincingly, the moment she's out of Jesse's sight she hands the baby away and complains that next time she wants to have a dog instead.
- Damsel in Distress: She seems to favour pretending to be this to get close to people, tailored to their personalities - thus, when spying on Jesse she pretends to be a world-weary moll in over her head and in need of an upstanding man to champion her, and when spying on Tulip she pretends to be a frail domestic abuse survivor in need of a tough chick to bond her with and teach her to stand up for herself. They both eat it up.
- Dark Action Girl: While violence isn't her first option, the Season 2 finale shows that she's both comfortable and capable with a gun.
- Hotter and Sexier: She uses her sexuality to complete her missions if need be. Compare her comics counterpart, a Sunday school teacher.
- Manipulative Bastard: She plays both Jesse and Tulip like fiddles over the course of the second season.
- Master of Disguise: When Tulip comes knocking at her door, it only takes her about five seconds (the time from closing the door and undoing the chain lock) to change her appearance entirely.
- Nightmare Fetishist: While her comic counterpart simply had an unhealthy interest in Starr, Sarah openly hopes that Starr wants to rape her. Starr, for his part, seems uninterested because Featherstone's not a prostitute.
- Survival Mantra: Whenever she's caught in a hopeless situation that seems to mean certain death for her, she sings "Onward, Christian Soldiers".
Featherstone's less formidable partner, assisting her in her work for the Grail.
- Adaptational Wimp: And the original Hoover isn't exactly a powerhouse.
- And Then John Was a Zombie: Gets transformed into a Vampire by Les Enfants Du Sang.
- Butt-Monkey: Hoover gets no respect, not from Featherstone and certainly not from Herr Starr. Getting his ribs broken for the cause only nets him a disgusted remark from Featherstone to stop whining like a woman. It gets even worse for him in Season 3. :After he gets abducted by Les Enfants du Sang, Herr Starr ignores the cult's text-messaged threats on Hoover's life, leaving him to die. He tries to survive by accepting their offer to become a vampire and is almost killed by Eccarius if not for Cassidy finding out about it. In the season finale, Herr Starr kills him by removing his umbrella hat and exposing him to the sun. To further cement how expendable Starr perceives him to be, his replacement introduced in Season 4 is given the label "Hoover 2".
- Can't Kill You, Still Need You: Starr would've killed him for getting him raped by a trio of men, but doesn't because he needs more than one person to help him convince Jesse to be the Messiah. However, after he gets turned into a vampire and Starr is prevented from wearing hats again, Starr feels indirectly insulted, removes Hoover's umbrella hat and has him burn to death in the sun.
- Hidden Depths: Hoover is surprisingly adept at both singing and the piano, which is shown when he accompanies Humperdoo during the latter's tap routine.
- Karmic Death: After he is turned into a vampire by Les Enfant du Sang, Cassidy saves him from being eaten by Eccarius. However, Hoover returns to their hideout later under the claim of quitting The Grail, only to have most of the cult killed before abducting Cassidy. Not much later, Herr Starr executes him by taking away his umbrella hat, having him die like a vampire.
- The Load: Hoover's gross incompetence is hilarious, but he's alive purely because Starr needs a warm body loyal to him. Unfortunately for him, becoming a vampire makes him even less useful to the Grail since he can't operate during the day without an umbrella hat, and Herr Starr has Hoover killed for unintentionally mocking his inability to wear hats again.
- Man in White: As a Grail agent, he wears a white suit.
- Not-So-Harmless Villain: While Hoover is far from impressive, he's scarily good at acting the part of a drunken, abusive ex-boyfriend, and his efforts allow Featherstone to continue her work spying on and sabotaging Tulip. He also leads the Grail to Les Enfants du Sang hideout and has almost all of them killed before abducting Cassidy.
- Punny Name: He is named after the vacuum brand. Vacuums suck.
- Rewarded as a Traitor Deserves: He becomes a vampire to save his own skin and is publicly accepted as a member of Les Enfants du Sang. He abuses his membership by selling out their headquarters to The Grail, which leads to all but three of them being killed and Cassidy being captured. Unfortunately for Hoover, Herr Starr is bitter over being unable to fashionably cover up the scar on his head and has Hoover killed by exposing him to sunlight, a weakness he gained from becoming a vampire.
- Scary Black Man: Definitely not one for real, but can believably pretend to be one when required.
- Too Dumb to Live: He gets turned into a vampire in Season 3. Given Herr Starr's lack of respect for him and The Grail's general attitude towards vampires, he should have known better than to come back and believe his newfound vampirism wouldn't be a detriment to his career.
- Trademark Favorite Food: He is fond of Boo Berry Cereal.
