This is a list of secondary and one-time characters and organizations from The Venture Bros. Characters are categorized by their first appearances.
- †Character is deceased
- ‡Character is either undead or dismantled
- Otaku Senzuri: A scientist and ninja with a fetish for deadly machines. He follows Dr. Venture's every move in New York in order to get the Oo-ray (his first and last names are both actual Japanese words, otaku meaning something akin to an obsessed fanboy and senzuri meaning masturbation). He is a parody of Dr. Julius No.
- Scamp†: The Ventures' dog. Was experimented on by Dr. Venture (his skin was removed for the sake of cosmetics research) and has since died.
- Prostitute: A prostitute in New York City who almost does business with Hank and Dean, who misunderstand her "services". However, when she takes them back to her home and gropes Hank's crotch, they immediately flee from her, horrified. At the end of the episode, she is shown in bed with Brock.
Season 1 Edit
- Speedy†: An over-enthusiastic henchman of the Monarch who is trying desperately to earn his wings. Was killed after Brock Samson grabbed him by the throat and never let go even while unconscious. Unable to break his iron-like grip, 24 shoots Speedy as a mercy-killing.
- Anna Baldovitch†: Bud Manstrong's love interest and only companion in space station "Gargantua-1". Even though they spend several years alone in space, due to Bud's repression, they never had a sexual relation. When the Ventures arrived to fix the station, she had sex with Brock Samson. Her body is attractive but her face (although never shown) is implied to be very unpleasant. Died when the space station crashed in "Guess Who's Coming to State Dinner?" but not before giving Manstrong a hand job. She was given a closed casket funeral in Russia, assumedly because of her ugliness.
- G.U.A.R.D.O.‡: Dr. Venture's bodyguard robot. He is made of titanium and has a screen on his head that always displays Dr. Venture's angry face and threatens to destroy intruders. Would later become the chassis for Jonas Jr.'s mechanical body until Brock Samson hits him with his car.
- Steve Summers: A former test pilot, he nearly died in a horrific accident but was saved when the government invested 6 million dollars into rebuilding him. However, the government has Summers work off his debt (all on a government salary) which he chafes under. He runs away after entering a homosexual affair with Sasquatch and was assisted in his escape by Brock Samson. He is a parody of Steve Austin from the Six Million Dollar Man. It was also this source material that inspired the Sasquatch storyline, as towards the end of the series, a big foot did appear.
- Sasquatch: See Bigfoot. A giant hairy creature whom Brock first encountered while camping leading to a brief altercation until Summers intervened. To escape the army, Brock shaves Sasquatch, only to discover that Sasquatch was a male.
- Roy Brisby: An obvious parody of Walt and Roy Disney, he's the visionary behind the Busy Bee cartoons and Brisby Land. Worked with and was good friends with Dr. Jonas Venture who built some of the rides at the park (which were tested on Rusty). Is wheelchair bound with facial paralysis after an accident left him trapped under an animatronic Abraham Lincoln for two hours, causing a stroke. He lives on Panda's milk which comes from his faithful "com-panda" Li-li, whom he won from David Bowie in a trivia contest. In an effort to prolong his life, he interrogates Dr. Venture for information on cloning (in a parallel to the urban legend regarding prospects of cloning Walt Disney). After Molotov Cocktease came to retrieve the Panda for Bowie, Brisby caught fire and was presumed dead, until he made a brief appearance at stanford in "pomp and circuitry".
- Mandalay: Brisby's silent, gigantic African not-so-loyal bodyguard. He resembles Brock Samson in that he appears to be another ultra-masculine hulking bodyguard in the employ of a VIP. However, while Samson is fiercly loyal to the Ventures, Mandalay backs down when confronted, leading to his only line: "Man, I don't even need this job."
- Li-Li: Brisby's giant panda formerly owned by David Bowie (recovered to Bowie). Li-Li provides panda milk for Mr. Brisby.
- Tommy†: A deaf quarterback that Brock Samson accidentally killed in college. Brock talks to him while is inside the "joy can".
- Major Tom†‡: See Major Tom. An astronaut whose experimental aircraft (designed by Jonas Venture) crashed into the ocean during a test run in 1969. He returns as a ghost. His name is a reference to the character from the classic David Bowie songs "Space Oddity" and "Ashes to Ashes." (Not coincidentally, most of Major Tom's dialogue is taken from both songs.) The aircraft's model name was TVC 15, another Bowie song, although one not dealing with spaceflight. Before his death, Tom had a wife named Jeannie who went on to marry the Action Man.
- Race Bannon†: See Jonny Quest. Brock's friend from the Office of Secret Intelligence. Died after jumping from a jet that Nat King Cobra's Snake Men were piloting while retrieving the Goliath Serum. He carries various spy gadgets (all of them extremely dangerous) that are reminiscent of those carried by James Bond. Soiled himself upon death.
- The Intangible Fancy: a mischievous ghost fond of spontaneously materializing and vanishing, he whispers cryptic messages in people's ears (no doubt to annoy them).
- Mister 1: The leader of the agents guarding the compound. Has a bizarre "men in dress[es] fetish." He and many of his agents were later seen working for Prof. Impossible, and later still with the Secret Service.
- Mister 5: One of the agents guarding the compound. Referred to by Doc Hammer as "Agent Hank", due to a similar appearance to Hank Venture.
- Misters 7, 11, 12, and 16: The other known agents. A Mister 20 was mentioned, but not seen.
- Mike Sorayama†‡: A former College friend of Dr. Venture, Pete White, and Baron Werner Ünderbheit. In college, he is target of mean jokes, each played by every one of his friends and Brock Samson. Several years later, Sorayama dies, but not before making arrangements to kidnap his four college friends at the funeral. After the original Team Venture arrived to rescue them, they discover that Sorayama is a robot and the real Sorayama is actually dead and in the coffin. He is a parody of artist Hajime Sorayama, famous for his paintings of sexualized robotic women, and the character Mike Yanagita from the movie Fargo. (Both Mike Yanagita and Mike Sorayama are played by actor Steve Park). He is possibly a parody of Dr. Julius No.
- Leslie Cohen: Mike Sorayama's crush in college who once slept with Brock Samson. She had a restraining order on Mike Sorayama.
- Lesliebots‡: Robots designed to look like Leslie Cohen. Closely resemble the female robot designs of Hajime Sorayama, whom Mike Sorayama is named after.
- Tiny Attorney†: A tiny southern man growing out of the torso of an "inbred simpleton". Despite his odd appearance, he is a competent attorney who specializes in prosecuting super villains. Was number three on the Guild's Most Wanted List and captured by Phantom Limb. His fate was not revealed until Showdown at Cremation Creek (Part I): he was used by Phantom Limb to help free Monarch's friends from prison and was rewarded for his service by being shot and killed by Limb. He is a parody of Kuato, the mutant resistance leader from the film Total Recall and of the "folksy Southern lawyer" stereotype.
- Mecha-Mouth: An inmate with a mechanical, spiked beak for a mouth. Head design resembles a Tusken Raider from Star Wars.
- Shame Face: An imprisoned inmate whose face and body were severely burned in an accident involving super-heated plasma. He seems to be a parody of comic books' post-silver age tradition of villains disfigured due to their own misguided actions. Such a theme is common in the Batman mythos with Two-Face and The Joker. Character is a play on the common idea that disfigured villains in comics generally have interesting or "cool" scarring as opposed to hideous disfigurement. In contrast to that, Shame-face is simply ugly and disfigured in a more reality-based manner.
- Dr. Septapus†: Septapus is so named for the fact that he has seven limbs (two arms on each side, one on his chest, and two legs). Dr. Septapus is a parody of the Spider-Man villain Doctor Octopus, but appears to have seven organic limbs instead of four natural and four cybernetic ones. Like Otto Octavius, he has a penchant for sporty glasses, but Septapus' hair is thinning on top. The creators of the program state that they had never heard of "the Mighty Septopus" from the Home Movies episode "The Heart Smashers". Freed by Phantom Limb only to be hunted and killed by him. May not actually be a doctor, Monarch struggles for a moment to remember his name when he refers him as "Doctor Septapus." He was previously referred to simply as Septapus until this point.
- Mister Monday†: A flamboyant villain with a monocle and a WASP-esque accent. He obsesses over bland and trivial things, namely anything that occurs on a Monday, and asks to be "President of Calendars" in The Monarch's group. He appears to be a parody of the DC Comics villain Calendar Man. He is also similar in appearance to characters Virman Vundabar and Baron Strucker. Freed by Phantom Limb, he was the first one killed, or at least shot at.
Season 2 Edit
- Hector Molina: Dr. Venture's (former) childhood friend. Was put to work in the Venture compound's manufacturing wing prior to Dr. Venture, Sr.'s, death. Has been there ever since until being unceremoniously fired by Dr. Venture. Is 45 years old and never kissed a girl. He may be a parody of Hadji.
- Swifty: Former middleweight boxer and body guard. He has become punch-drunk as a result of his career: rambling nonsensically which caused his wife to leave him. Was put to work with Hector in the manufacturing wing by Jonas Venture until fired by Thaddeus Venture.
- Tigeriffic: While this is his only appearance, Tigeriffic was first mentioned in a deleted scene from "The Trial of the Monarch" as a purported "peer" of The Monarch. While operating as a supervillain, he wore a tiger suit that granted him super-powers. He is not, contrary to popular belief, "half tiger, or something," nor was he raised by tigers. The Monarch claims to have once seen him "cleave an Eyewitness News van in twain." His appearance is most likely patterned after Tygra, one of the ThunderCats.
- White Noise†: This villain, whose powers and abilities are unknown, speaks in a stereotypical southern accent and displays white supremacist views. His body transformed into something resembling video static when he tried to repair a television while it was plugged into a live socket. He asks The Monarch if the group involved in the escape includes other races because he doesn't want to "muddy" his "pure white blood". The Monarch, in response, questions whether White Noise even has blood anymore. Was freed in Showdown at Cremation Creek (Part I) and shot by Phantom Limb, losing an arm, possibly his life.
- Tiny Eagle: An operative for Phantom Limb. Approximately the size of Tiny Joseph.
- Manaconda (also Womanaconda)†: A cross between an anaconda and a man (later determined to be female, hence womanaconda). Sliced in half by Molotov Cocktease, after which babies crawl out from its corpse.
- The Perfect Man†: Created by the Cult of Osiris. Almost twice the size of an average male human. Dr. Venture tells Brock to kill him, as he is "an abomination." Appears to hate his own foot. Was later ridden by Dean's head (atop the body of Mummy Mum Muggy) in the attack on the cultists.
- Edgar Allan Poe†: See Edgar Allan Poe.
- Caligula: See Caligula.
- Dr. Sigmund Freud: See Sigmund Freud.
- Mummy Mum Muggy: A good mummy with a magic scepter whom Hank befriends. Loses the upper half of his head due to this and is later ridden by Dean's disembodied head into battle.
- "Master": Dr. Orpheus's teacher and mentor, who often takes on different forms to teach Orpheus a lesson. (In this episode, he shape-shifts into the form of Cerberus, the three-headed dog.)
- Grand Galactic Inquisitor†: An alien who arrives at the Venture compound to pass judgment on mankind. He constantly issues the command "IGNORE ME!" which is impossible to follow given his towering size and the volume of his voice. Shot and killed by an alien posing as Jonas Venture, as he would apparently have destroyed Earth. With his boisterous insistence on judging, his towering stature, and his insistence that others ignore him, the Grand Galactic Inquisitor seems to be fashioned after the Marvel Comics character The Watcher, though his helmet resembles that of Galactus. He may also be a reference to The Inquisitor from the Red Dwarf episode of the same name.
- Jonny Quest: See Jonny Quest. Since the death of Race Bannon, he has been secreted away within the Quest diving bell, feeding (when possible) his addiction to narcotics. Is fooled into handing over a piece of Dr. Venture Sr.'s machinery after being bribed by the Captain and Jonas Jr., an act that Jonas Jr. resented.
- H.U.G.G.Y: A robot nanny used to raise Rocket Impossible. He is a parody of the Fantastic Four's robot nanny H.E.R.B.I.E.
- JollyRancher82: A young woman who meets The Monarch online and goes on an ill-fated double date with him. She is a fan of cosplay.
- Torrid: A fire-based Australian supervillain under the Guild's banner and one of many who applied to be the Order of the Triad's archnemesis. He got the position after telling the group he had kidnapped Triana and sent her to the 'Torrid zone' (another term for tropics). Has gas issues. His appearance seems to be based on the DC Comics superhero Deadman. The fact that he's Australian and controls fire may be a reference to Marvel Comics villain Pyro. It is also possible he is based on Dormammu, the arch-nemesis of Dr. Strange of whom Dr. Orpheus himself is a parody.
- The Walking Eye: A four-legged robot built by Dr. Venture that does, essentially, nothing of purpose. Looks exactly like a robot appearing in a Johnny Quest episode.
- The Moppets: When Dr. Girlfriend assumes the role of Lady Au Pair, she employs these two midgets, dressed in Dutch schoolboy outfits, as henchmen.
- President Breyer: The residing president in the Venture Bros. universe. He is an amalgamation of Bill Clinton (sex scandals, love of cigars), George W. Bush (terrorists, pronunciation of nuclear as "nuke-a-ler", previous alcoholism), and Lyndon B. Johnson (physical resemblance, accent).
- Mrs. Manstrong: Bud Manstrong's somewhat controlling and alcoholic mother. A parody of the mother played by Angela Lansbury in the 1962 version of The Manchurian Candidate. Tries to flirt with Brock Samson during the state dinner, who rejects her (increasingly bold) advances, to the point where he ends up making a scene after she gropes him under the dinner table.
- The Ghost of President Lincoln‡: See Abraham Lincoln. The ghost of the 16th President of the United States is still around in the White House and with the help of the Venture brothers, saves current President Breyer from being killed by Bud Manstrong and his manipulative mother. Because of their previous visits, he is familiar with the Venture family. Lincoln is animated in a manner strongly reminiscent of the Force ghost, from Star Wars.
- Hauser: A government agent who works at the White House. Met Brock Samson sometime in Vietnam (but not during the war). He and Brock have tensions with each other.
- Dr. Henry Killinger: A cross between the diplomat Henry Kissinger, the magical nanny Mary Poppins, and a stereotypical super villain, he never goes without his "magic murder bag". The Monarch hires him as a new "number two", and he to implements new reforms into the Cocoon and attempt to turn around their spectacular failures. He ends up reuniting Dr. Girlfriend with the Monarch, and it is implied that this was his intention all along. He was responsible for the Oni's attempt to reunite Myra Brandish and Dr. Venture as well. His reforms for improvement are only hampered by the fact that people cannot understand him too well.
- The Oni‡: A demonic Japanese spirit, it temporarily possesses Dr. Venture.
- Texas† / Venturestein‡: One of The Monarch's former henchmen, Texas was killed by Brock during an attack on the Venture compound. Dr. Venture re-animates him as part of an experiment to create an army of undead soldiers/manual laborers, renaming him 'Venturestein'. Brock is forced to kill him once more when Venturestein sees himself in the mirror and chokes Dr. Venture because of this. Venture then replaces the crushed top of his skull with an African American cranium top. As an apology for killing Venturestein, Brock takes him to a prostitute.
- Ted†: The outwardly charming but actually sociopathic leader of "The Groovy Gang," a group comprised of four aging, unstable hippies and their evil dog, who "solve" mysteries, (which is an obvious parody of the cartoon Scooby Doo). Ted is a parody of both Ted Bundy and Fred from Scooby Doo. Killed from a headbutt by Brock Samson.
- Val: A chain smoking lesbian with an intense hatred for men, Val is a parody of both Valerie Solanas and Velma Dinkley from Scooby Doo. At one point, she quotes the S.C.U.M. Manifesto. She,along with Patty, were the only one to escape death of Brock and Texas.
- Patty: A timid, emotionally fragile woman who is constantly terrorized, abused, and tortured by Ted. The Groovy Gang has been on the way to "her parents' house" for the last ten years. Patty is a parody of Patty Hearst and Scooby Doo's Daphne Blake. She,along with Val, were the only to escape death from both Brock and Texas
- Sonny†: A jittery, drug-addicted hippie, Sonny once "killed" Hank and Dean Venture when they accidentally startled him (he beat Dean to death with his flashlight while Groovy mauled Hank). Unaware that the boys are clones, Sonny goes over the edge when he later sees them as "ghosts." Sonny is a parody of David Berkowitz, also known as the "Son of Sam" killer, and Scooby Doo's Shaggy. Accidentally shot when Ted's gun went off during his struggle with Brock.
- Groovy†: A dog who speaks only to Sonny (in a German accent) and urges him to commit murder. Groovy is a parody of Scooby Doo and Harvey, the "demonically possessed" dog that Berkowitz claimed compelled him to kill. Strangled to death by Venturestein who then turns Groovy's paw into a shoe.
- Everyday Joe: A generic narrator of a 1960s educational film, extolling the joys of child labor and "bondaged servitude".
- Don Rio: A jocular shaman and spirit guide is a parody of Don Juan Matus, the Yaqui shaman from the Carlos Castaneda novels.
- Truckules: A giant man who either wears a truck or has one for a torso (like Optimus Prime). Also wears a Greek skirt. Was once partners with Dr. Girlfriend and listed as one of those Monarch considers a "peer" in a deleted scene in "The Trial of the Monarch".
- Sergeant Hatred: Previously seen in "Fallen Arches", he is a large man with a giant red 'H' painted on his face and wears military fatigues much like the Marvel villain Nuke. The Monarch's henchman, namely 21 and 24, routinely steal parts from Hatred's technology, using his hover tank to rebuild the cocoon and 21 stole jet packs from him as well. He also once captured Hank and Dean and subsequently molested them - an experience only Hank remembers (Dean was passed out from the wine). Dates Princess Tinyfeet and has a massive foot fetish. It is unknown how he got his Guild license, as "Inappropriate Behavior" is strictly prohibited in the Guild.
- Princess Tinyfeet: Sergeant Hatred's silent guest to the wedding. She is a short Native American princess who, as her name suggests, has tiny feet. Her gaze never wavers and she does not seem to mind when Hatred inappropriately slobbers over her feet.
- Klaus Nomi†: See Klaus Nomi. Traitorous bodyguard for David Bowie. Could blast an ultra-sonic cry and had a special tuxedo made of plastic with an oversized bow tie capable of being ejected.
- Iggy Pop†: See Iggy Pop. Traitorous bodyguard for David Bowie. Agile, and capable of creating explosive energy globules that he can then "Pop". May not be dead, as his fall, but not his landing, is shown on-screen.
- Nien Nunb†: See Nien Nunb. Was accidentally materialized from a trading card by the Order of the Triad. He is the same character from Star Wars that is a pilot for the Rebel Alliance. Not surprisingly, he is able to pilot the Ventures' X-1. Nunb is gruesomely killed when he and Orpheus crash the X-1 into The Monarch's flying cocoon.
- The Krampus: See Companions of Saint Nicholas. Accidentally summoned by Dean Venture as he and Hank tried to find a Christmas story in Dr. Orpheus' book. Fabled as the demon who used to ride alongside Santa Claus and punish the naughty kids, apparently by spanking them with a bunch of sticks he carries around. The Krampus always carries a backpack with two children peeking out of the top. He is also one of the few characters that can match Brock Sampson in hand to hand combat.
