Characters from The Venture Bros.. This page is for the current and ex-members of the OSI.

The Office of Secret Intelligence, the US government agency which stands in opposition to the Guild of Calamitous Intent. OSI headquarters is a Global Airship that houses more than two thousand crew, and is almost always on the move. During season 4, most of the OSI members that were (or became) main cast members had defected and joined SPHINX, a terrorist organization they had eliminated in the 1980s which they turned into a vigilante group to deal with supervillains not affiliated with the Guild. By the end of the fourth season, General Treister appointed a reluctant Hunter Gathers as the new leader of OSI, just before Treister launched himself into space. As of season 5 Gathers' has taken to the job and taken all of his SPHINX with him, barring Gary. This section includes past and present OSI members, excepting those who have left and joined other organizations.

    Col. Hunter Gathers
"Lesson number one: trust no one! The minute God crapped out the third caveman, a conspiracy was hatched against one of them!"
Voiced by: Christopher McCulloch
Brock Samson's world-weary, boisterous mentor and current head of the OSI.
  • Above Good and Evil: According to Brock's psychotropic hallucination in ¡Viva los Muertos!, Hunter believes working for the government makes one beyond good and evil.
  • Amazonian Beauty: His post-op body is actually more ripped than his pre-op one.
  • Arbitrary Skepticism: Doesn't believe in vampires despite the fact that they exist in the Venture-verse. Granted, he's only explicitly expressed this belief in a flashback, but when Pete White tells him that Billy's been captured by vampires he refuses to take him seriously until he figures out it's actually the Investors.
  • Attractive Bent-Gender: Subverted in that while the his sex change fulfilled his dream "to have big beautiful tits", his post-op body being quite nice, his face and voice remained exactly the same.
  • Big Good: When the extent of his manipulations to restore SPHINX come to light, Gathers takes this role on the show. Eventually the other Big Good, Treister, hands off the OSI to Gathers making him the leader of the de-facto heroic faction in the Ventureverse.
  • The Chessmaster: He manages to pull off some elaborate schemes, although they often fall into Gambit Roulette.
  • Double Reverse Quadruple Agent: The sex change operation was reversed and Hunter was a triple-agent working for SPHINX. Even a psychic couldn't see that one coming.
    • Also "Operation P.R.O.M." goes from the usual spy business to Treister already taking care of the double agents and shooting himself into space, leaving Hunter in charge of the OSI
  • Drill Sergeant Nasty: He began Brock Samson's OSI training with a metal baton to the kneecap.
  • Easy Sex Change / Magic Plastic Surgery:
    • Played with. It's quick compared to real life, in that he just kidnaps a top plastic surgeon to perform it in an ancient temple. However, the work done is shown in the scars, stitches, and medical tape on Gather's body from all the incision sites.
    • The reversal is played straight in that it seemingly happens instantly with no lingering side effects. However, when disguised as Rusty Venture for a sting operation in Season 6, he can be seen with what appears to be a camel toe while wearing Rusty's "speed suit," meaning that the reversal may not have been complete. (This would avert the trope and play it closer to reality, where reversing a male to female sex change is incredibly difficult and is one of the reasons why it is not "easy" to get one in real life.)
  • Establishing Character Moment: The flashback depicting his and Brock Samson's first meeting.
    Brock: You Colonel Gathers?
    Gathers: What? Oh no, you don’t! *pounces on Brock, combat knife drawn* What do you want from me? Who sent you, you bastard?
    Brock: Personnel. Special Agent-In-Training, Brock Samson, reporting for duty. *salutes*
    Gathers: Don’t you salute me, you bastard! *stabs him in his saluting hand*
    Brock: Ow!
    Gathers: Leave that Little John John crap back in Biloxi.
    Brock: Yes, sir.
    Gathers: And don’t "Sir" me, damn you! You’re not in the Marines anymore. This is intelligence - start using it!
    Brock: Okay, Colonel, uh...
    Gathers: Call me Hunter.
  • Gambit Roulette: A rather gigantic one that is either a patently insane Roulette or the world's best-played game of Xanatos Speed Chess.
  • Good News, Bad News: Subverted in the Season 3 episode, ORB, when Brock comes to him for help in trying figure out why his car tried to kill him when he activated a certain code.
    Gathers: "Do you want the bad news or the good news first?"
    Brock: "I don't know...the good, I guess—"
    Gathers: "THERE IS NO GOOD NEWS! Just bad news and weird news..."
  • No Celebrities Were Harmed: His appearance, voice, and mannerisms are based on the public persona of Hunter S. Thompson.
  • Noodle Incident: He frequently throws out snippets of anecdotes about the "true" history of the United States, such as the fact that OSI has been defending the country since the Second American Revolution - "the invisible one!" Also that "the president isn't the president anyway, you know that."
  • Oh, Crap!: During "OSI Love You" when he realizes the three OSI agents interviewing everyone involved in the "Monstroso" incident were impostors.
  • Parental Substitute: Brock claims Hunter was the second-closest thing he had to a father.
  • Perma-Stubble: Always has 5 O'Clock shadow even after his sex change.
  • Properly Paranoid: Always tells Brock to be wary of conspiracies. He's proven that he's quite a Chessmaster, so it's wise to listen to him.
  • Running Both Sides: His fate in the season four finale; he's placed in charge of SPHINX and OSI.
    • Subverted in season five. He and the rest of SPHINX return to OSI while leaving Henchman 21 in charge.
  • Secret Test of Character: To Molotov after OSI supposedly captures her and Monstroso. Her whole break out was to test the OSI security against her as well as take out the double agents within. She passes with flying colors.
  • Sexy Mentor: Parodied post-sex change when he was working at a strip club. He still had his old face and voice despite having a nice body, and Brock's visibly disturbed when Hunter passes him information during a lap dance.
  • Sink-or-Swim Mentor: When he is training Brock. When he learns that Brock can't swim, he forces Brock into a pool where he must fight frog men and an alligator while Hunter throws grenades into the pool.
  • Training from Hell: Largely responsible for turning Brock Samson into a one-man army.
  • Transgender: He eventually had it reversed, but later admits to miss being a woman. Or at least having a pair of breasts.
  • Wouldn't Hit a Girl: Would hit ("non-lethal force only") but wouldn't kill. Instills this philosophy in Brock Samson during the latter's training, and takes advantage of it later when he undergoes a sex change so Brock couldn't kill him when he quits the OSI.


Shore-Leave/Holy Diver
Voiced by: Doc Hammer
"Nooo, no. That's not my gun. That's an indicator of how excited I am to do this to you. That [holds his gun up] is my gun."

An ex-OSI operative kicked out on a Don't Ask, Don't Tell violation, Shore-Leave claims to have exorcised the "demons of homosexuality" and turned to God. He and his Heterosexual Life Partner Sky Pilot run a Bible camp for kids and dress up as the Christian superheroes "The Soul Mates."

In fact, the religious conversion was a cover story; Shore-Leave is one of the top agents in Hunter Gathers' SPHINX organization. He becomes Brock Samson's partner on missions and The Alchemist's outside of them.

  • Agent Peacock: According to Word of God on the DVD Commentary, Shore Leaves plays up his "swishiness" a little bit because he enjoys creating a contrast between his Camp Gay flamboyancy and his badass lethality, just to underscore how awesome and confident he is at both.
  • Agent Scully: Back when the OSI was fighting SPHINX, he refused to believe the Guild was anything but a "phantom costumed terrorist organization". He's wised up since then.
  • Ascended Extra: From a bit character to one of the cast mainstays.
  • Badass Gay: Flamboyant as he is, there's a reason Shore Leave is usually Brock Samson's partner during SPHINX missions - he's at least as badass as Brock himself.
  • Bunny-Ears Lawyer: Despite his eccentricities, he's a top-tier agent.
  • Busman's Vocabulary: Everything can be expressed with a Bible reference as far as he and Sky Pilot are concerned.
  • Camp Gay: An unusual combination of this and badass.
  • Catchphrase: "BOOM! Yummy!"
    • Also, briefly "Sphinx!", said whenever one of his teammates' mentions the organization, which itself was a running gag when SPHINX was first introduced, when every time it was mentioned a female backup team sang it..
    Shore Leave: Sphinx! *it hadn't been said* Well it was implied!
  • Didn't Think This Through: Learns pretty quick that diving into the freezing ocean, in nothing but a speedo, is a bad idea.
  • A Good Name For A Superhero: According to Doc Hammer, he was created just because Doc desperately wanted to use the name "Holy Diver" for a character.
  • Guns Akimbo: Favors twin pistols when it comes to combat.
  • The Gunslinger: In contrast to Brock, Shore Leave seems to specialise in gunplay.
  • Hello, Sailor!: A walking stereotype and a parody of Shipwreck from the G.I. Joe cartoons.
  • Improbable Aiming Skills: Shore Leave is deadly accurate with his pistols, being able to shoot specific targets on 21's costume from a large distance. One handed. He even mocks Sgt. Hatred for using a scope while he's at it.
  • Incredibly Lame Pun: "Holy Diver" is a sailor with an anchor/cross tattoo on his chest; he was specifically created around this idea. Sky Pilot has a matching up arrow/cross tattoo, but it's not as punny.
  • Jerk Jock: Back when the OSI was fighting SPHINX, he liked to taunt and mock Brock and Hunter for hunting down the Guild, which he dismissed as a "phantom costumed terrorist organization," instead of helping fight SPHINX. He's mellowed out since then.
  • Macho Camp: As camp as you can get, but is not a sissy.
  • Meaningful Rename: Subverted. He renamed himself "Holy Diver" as part of his religious cover-up story, but went back to "Shore Leave" when he joined SPHINX.
  • Mr. Fanservice: He's very attractive and often plays it up with skimpier clothing than many of the other OSI agents. His "Genital Formalwear" being one of the most direct examples.
  • No Celebrities Were Harmed: He and his clique of OSI buddies are Village People reimagined as G.I. Joe operatives. Lamp Shaded with an X Called; They Want Their Y Back:
    Col. Gathers: Oh yeah? The Village People called, AND THEY WANT YOU TO GO FUCKING KILL YOURSELF, YOU PRANCY BASTARD! Place has gone to Hell in a ham sandwich since they 86ed the dress code.
  • Porn Stache: He has a giant Village People style mustache.
  • Power Glows: Subverted: the glowing sword is just a plastic prop. Props, apparently, really drive the Word home with the kids.
  • The Reveal: He turns out to be an operative of SPHINX, and appears to be Hunter's right-hand man up until Brock joins. Sky Pilot, too, but whatever.
  • Shout-Out: We dare you to find another Bibleman Shout-Out in anything, ever.
    • And their OSI identities as Shore-Leave and Mile High are based specifically on Shipwreck and Airborne from G.I. Joe
    • "Holy Diver" itself is a pretty obvious shout-out to the Ronnie James Dio song of the same name.
  • Transformation Sequence: Parodied with his over-long armor-up sequence.
    "Activate! Boots of the Gospel!"
    • And the constant neck craning with every syllable.


Mile-High/Sky Pilot
Voiced By: Christopher McCulloch

Another former OSI agent, kicked out alongside Shore-Leave, who ended up being part of Hunter's SPHINX group as well. Doesn't play as active a role in the series as his former partner. Most of the same tropes associated with Shore-Leave (in relation to religion and the defection, at least) are shared by Mile-High.

  • Meaningful Rename: Unlike Shore Leave, he kept the name "Sky Pilot" after joining SPHINX.
  • The Mole: He's still working for OSI, as revealed by General Treister.
  • Satellite Character: Disappears once Shore-Leave pairs up with Brock.
    • He lampshades this when he finally does go on a mission, and proceeds to demolish this trope entirely when he's revealed as The Mole in SPHINX for the OSI.
  • Shout-Out: To the Animals song.
  • Straight Gay: Possibly. He's not in love with Shore-Leave, but may still be gay due to Shore-Leave offhandedly mentioned how they were having sex while they were pretending to be in love with each other.
  • Walking Shirtless Scene: Rarely, if ever, wears a shirt.

    Headshot and Amber Gold
Voiced By: Bill Hader (Headshot), Paget Brewster (Amber Gold)

An OSI Couple introduced during the capture of Monstroso and Molotov Cocktease.

  • Crippling Overspecialization: Headshot is a good sniper...and that's about it for his skill set. Most of the time, that would be perfectly fine. But for an OSI agent, whose duties may range from infiltration to hand-to-hand combat with legitimately powered supervillains, it's rather lacking.
  • Early-Bird Cameo: Amber Gold shows up in the commissary with Brock and Shore Leave the episode before her full debut.
  • Expy: Of comic book Battle Couple Hawkeye/Mockingbird, and Green Arrow/Black Canary.
  • Friendly Sniper: Headshot, though snarky and a bit of a Jerkass, is closer to the "friendly" end of the spectrum rather than the "Cold Sniper" end.
  • Hairstyle Malfunction: Amber Gold is revealed to wear a platinum blonde wig because her real hair color is a darker dirty blonde unworthy of her codename.
  • Jerkass: Headshot. He constantly needles Brock about his relationship with Molotov and overreacts when it turns out Amber is really a dirty blonde rather than a regular blonde.
  • Spy Catsuit: Amber Gold
  • Your Cheating Heart: Amber is implied to be cheating on Headshot with Brock. It's confirmed in "All This and Gargantua-2. "
    • Considering Headshot's attitude we can hardly blame her.

    Gen. Treister 

Gen. Timothy Treister
Voiced By: Toby Huss

"Well, while your head is up there, can you take a look at my prostate? Daddy fears the can-cer."

The former head of the OSI and apparently its founder. He's a Crazy Awesome badass. Or at least he was, until he launched his body unprotected into space, with a note asking aliens to cure his prostate cancer.

  • Arbitrary Skepticism: He may be familiar with mutants, super science, and aliens, but the existence of Zeus is just silly. For bonus points, he dismisses the idea that "Zeus" is real out of hand mere moments after he accepts Brock's proposal that as a metahuman he can really fly instead of using a jetpack or being a hologram.
  • Back for the Dead: Granted, it's an INCREDIBLE example of this trope in action.
  • Beware the Silly Ones: He is a rather hammy and odd fellow, but Treister is a very capable and powerful man sometimes in spite of those eccentricities and sometimes because of them.
  • The Chessmaster: Is able to stay one step ahead of the Guild's plans to undermine and replace him with Guild moles Cardholder and Doe, even factoring in S.P.H.I.N.X. commander Hunter Gathers' own attempt to thwart them by having multiple inside men of his own within S.P.H.I.N.X. He also manoeuvres Hunter into literally and figuratively taking the wheel of the O.S.I.'s hoverquarters, having deduced he's a worthy successor, before leveraging the lives of the crew to stop Hunter letting go of the wheel to prevent Treister firing himself out of a torpedo tube.
    "Nothing's ever what it seems. First rule of espionage."
  • Cool Old Guy: Though he is a bit of a Cloud Cuckoolander (probably comes with the territory of running an ultra-secret espionage organization), he is undoubtedly badass.
  • Crazy Enough to Work: This crazy son of a bitch launches himself into space, hoping aliens will cure his "Pee-pee cancer". Turns out space radiation fixes it for him.
  • The Cuckoolander Was Right: Not only did cosmic radiation cure his prostate cancer, it made him into a Hulk.
  • Expy: He's essentially a combination of Earth-616 Nick Fury And General Thaddeus "Thunderbolt" Ross. Right down to getting his own Red Hulk persona. There's a bit of Theodore Roosevelt in there, too.
  • A Father to His Men: Tells Brock this when he thought OSI put a hit out on him. Turns out they weren't the ones who did it and Treister was trying to help Brock during the whole escapade.
  • Heroic Sacrifice: In All This And Gargantua 2, his Hulk form help J.J detach the nucular core from the space station and he rides it out into space as it explodes.
  • Leave No Witnesses: Presumably in the name of security, in Any Which Way But Zeus he seems to be, if anything, very happy to shoot dead people who've wound up on the wrong golf course on the wrong time.
  • Obfuscating Stupidity: He knows of secrets even Hunter Gathers is unaware of, all while acting like a rather naive fellow. He upgrades this to Obfuscating Insanity when he pretends that he truly believes himself to turn into the Hulk. This is a ploy to flush out the two OSI moles Cardholder and Doe who are gaslighting him to turn him insane and take over the OSI.
  • Put on a Bus: He shoots himself into space so that aliens would cure his cancer. Though that doesn't happen, he instead gets radioactive superpowers before dying in a Heroic Sacrifice.
  • Real After All: Turns out he can turn into a Hulk.
  • Riding the Bomb: How he goes out in All This And Gargantua 2.

    Doe and Cardholder
Voiced By: Doc Hammer (Doe) and Christopher McCulloch (Cardholder)

High ranking members of the OSI who serve as Treister's top men.

  • Dirty Cop: They're actually spies, but they speak and act like a mix between cops and mobsters. They actually are the espionage version of this, being double agents for the Guild.
  • Deadpan Snarker: Well, sort of. They are snarkers, and are completely deadpan, but somehow aggressively so.
  • Expy: Of fasttalking L.A. police detective Joe Friday and his partner, Officer Bill Gannon, from Dragnet.
  • Finishing Each Other's Sentences: Constantly doing this, even in cases when one of them finishes a sentence. In those cases, it's merely expanding on what the previous person said (such as expanding "Emperor Doe" to "God Emperor Doe").
  • Meaningful Name: They're meant to sound generic. Doe comes from John Doe. Calling someone "Mr. Cardholder" refers to the blanked names on credit card commercials.
  • The Men in Black: A pair of "exterminators" sent by [OSI] to deal with Jonas Jr.'s "butterfly problem".
  • The Mole: For the Guild.

    Molotov Cocktease
Voiced By: Mia Baron

Molotov is a former agent of an unnamed Soviet intelligence organization who turned mercenary after the Cold War. She is the love of Brock Samson's life, despite the fact that a titanium steel chastity belt and a promise to her deceased father prevent their full carnal union. Before she was a secret agent she was an Olympic athlete representing the Soviet Union. Her father and trainer was an undercover Soviet assassin.

  • Heel–Face Revolving Door: To the point that its never exactly clear whose side she's really on; she often forms an alliance with a certain faction, only to reveal herself as a double agent. Currently working for the OSI.
  • Impossibly Tacky Clothes: Her off-duty outfit. Brock assumes it's some kind of disguise when her first sees it.
  • Manipulative Bastard: She indirectly tricks Brock into being paranoid about the OSI so he'll kill her Black Hearts' top rival assassins.
  • Meaningful Name: As Brock constantly finds out on his encounters with her. Brock even refers to her as a cocktease in one of their earlier meetings years ago.
  • Ms. Fanservice: Her default outfit is striperiffic and shows Absolute Cleavage.
  • Nebulous Evil Organization: It's never made clear exactly which agency she worked for during the Soviet Era, though notably, she attempted—and mostly failed—to train Hank and Dean to take care of themselves using a GRU handbook.
  • Never Found the Body: In the season four finale, she and Monstroso presumably fall to their deaths, but all we see is Brock looking away from the limo exploding.
    • In the season 5 premiere episode, Brock and Shore-Leave check out the wreckage, the only thing they find is a balloon shaped in Monstroso image and neither she nor him are anywhere to be found. Four episodes later confirm she's still alive.
  • Out of Focus: After being revealed to be working for the OSI in season 5, she largely disappears from the series, being completely absent from seasons six and seven.
  • The Only One Allowed to Defeat You: To Brock.
  • Red and Black and Evil All Over: The colors of her Spy Catsuit and her Black Hearts' uniforms.
  • Sexy Backless Outfit: Combines this with a very exaggerated Absolute Cleavage in her outfit.
  • Spy Catsuit: Her standard clothing of choice.
  • Stripperiffic: Wears a black catsuit with a neckline down well past her navel.
  • Villainous Cheekbones: She has somewhat pronounced cheekbones and is a Femme Fatale who later turns out to be more of a Vamp.
  • You Killed My Father: To Brock. OSI Love You reveals the whole details.

    Myra Brandish
Voiced By: Joanna Addler

A former OSI agent. She was at one point Dr. Venture's personal body guard and one time lover. Claims to be Hank and Dean's mother, though whether or not this is true is yet to be made certain. Brock claims she was a former member of the American Gladiators who was thrown into an insane asylum after becoming criminally obsessed with Dr. Venture. Every few years she breaks out of the asylum and kidnaps the Venture brothers.

  • Beware the Silly Ones: Though comically delusional and objectively insane, her debut appearance quickly establishes her as one of the Venture Family's deadlier adversaries. Even Brock clearly dreads having to deal with her.
    Brock: Oh crap, Myra's back.
  • Bodyguard Crush: She had an affair with her former charge which eventually spiraled into catastrophe for her.
  • Butterface: Still in great shape for her age. Her face however, thanks to a boatload of crazy, didn't age as well as the rest of her.
  • Crazy Cat Lady: She breast-feeds her cats and tries to kidnap Hank and Dean Venture.
  • I Was Quite a Looker: She was an attractive woman when she worked for Rusty. But all those years of crazy really changed that.
  • Love Makes You Crazy: And she's only gotten crazier since.
  • Multiple-Choice Past: The only things definitively known are that she actually was Rusty's bodyguard at one point, and that he really did sleep with her at least once; other than that it's "he said, she said"
  • Parental Incest/Incest Subtext: She tells Dean to get undressed, calling his body "handsome" and tries to have him shoved up her lady parts to give "birth" to him (fortunately she fails). Though it's not made clear whether or not her motives are purely bat-shit maternal crazy or maternal and sexual. It's only implied that it's both. Also she may not be their real mom. Though it may still be counted as playing the trope straight, even if that is the case, as they both saw each other as family during the time and she did try to give birth to him by shoving him in her lady parts.
  • Prison Riot: Managed to convert a whole crazy house into her own little personal cult army and took it over at least until Hank and 21 loused that up. Then again she was a former OSI agent.
  • Tiny Guy, Huge Girl: Is much taller and bigger than Rusty.

    Race Bannon
Voiced By: Christopher McCulloch

The original bodyguard of the Quest family from Jonny Quest, whom the character Brock Samson was designed to parody. In The Venture Bros., Race was an OSI agent who also knew Brock. Race was killed off quickly after his first appearance in the show, but appeared again later in the series in Flashbacks.

  • Death by Cameo: Died in the first season in his first appearance before the opening credits even start.
  • Heroic Comedic Sociopath: Can cheerfully greet Brock even while gruesomely torturing a detained SPHINX agent.
  • Writing Around Trademarks: Race Bannon has had no more mentions and appeared in no more Flashbacks since the creators of The Venture Bros. lost the right to use Jonny Quest trademarks (his last appearance lasted about 5 seconds and had Gathers calling him "Red").

Voiced by: Jon Hodgeman

Hunter's assistant and general Mission Control.

  • Non-Action Guy: One of the few OSI agents seen on screen who isn't a killing machine.

    Kimberly McManus 
Voiced by: Christopher McCulloch ("Red Means Stop") Katie Flahive (All subsequent appearances)

An OSI Mook in a relationship with a Guild Stranger.

  • Amazonian Beauty: She's at least six-feet-tall and revealed to be pretty buff out of her armor. None of this detracts from her attractiveness as Guild Stranger S-464 falls in love with her, and Watch and Ward both compliment him on having such a beautiful girlfriend when they see the computer code detailing her looks.
  • Dating Catwoman: She's an OSI Agent—ostensibly a heroic organization—involved with a Mook working for her organization's mortal enemy, the villainous Guild of Calamitous Intent.
  • Everyone Has Standards: She's willing to date a Guild Stranger because his evil organization at least has rules and standards. When she finds out he's secretly a mole for another super villain group, the Peril Partnership, she dumps him because she considers them to be honor-less scum. She only takes him back after he becomes a double agent for the Guild.
  • Samus Is a Girl: Played for all it's worth in her first appearance, complete with being voiced by a guy. Her following appearances have her voiced by Katie Flahive.
  • Statuesque Stunner: At least six-feet-tall and gets a lot of attention from guys.


How well does it match the trope?
