Steve's best friends

• Schmuley "Snot" Lonstein – Steve's best friend with whom he shares a bromance,. Snot is a mustached and acne-covered Jew. He is physically modeled after his voice actor's character's appearance from the movie Revenge of the Nerds, as Dudley "Booger" Dawson. Since Snot was a toddler and throughout much of the series, he had a crush on Hayley; however, in "The Missing Kink", when Hayley finally succumbed to Snot's advances and began to desire him romantically, Snot lost interest in her and deceived her into thinking he was gay, claiming it was the act of pursuing her that aroused him. He speaks Klingon, and can read Quenya. Like Steve, he has a fetish for octogenarian women. His parents are poor, as they could not afford a bar mitzvah celebration, although Steve pays for one in an attempt to apologize when he is falsely accused of theft. His parents have him see a therapist who is implied to engage with him inappropriately and romantically. Steve reveals that his father left Snot's family and may have been abusive towards his mother. He is generally considered Steve's best friend but is quite fickle in this role, having cheated with Steve's girlfriends and pelted him with apples during a period where Steve was in a brace for scoliosis in order to gain social acceptance. When Snot and Steve were younger, they solved mysteries together. He refused to help Steve figure out the mystery, as he quit when "the case of the missing bike horn turned into a double rape homicide". Snot appears to be the least eccentric member of Steve's clique. It is also revealed in the episode "Wiener of our Discontent" that he can somewhat understand Toshi. Toshi exclaims "Oh, my God", and Snot replies "I think you mean 'oh, my Godzilla'."
• Toshi Yoshida – Steve's Japanese American sansei friend. Though he can understand English perfectly, he always speaks Japanese with subtitles. A running gag is everyone misunderstanding Toshi, assuming he has said something completely different from or opposite to what he has actually said. Toshi studies Russian in order to impress an attractive mail order bride named Svetlana in "Of Ice and Men". He is mischievous, and sometimes, cruel and anti-American. Toshi has expressed the desire to kill Steve as his greatest wish, and he claims to have killed before. Toshi used a katana to kill a group of serial murderers who were chasing the Smith family in "Best Little Horror House in Langley Falls". Toshi has demonstrated that he is the only character outside the Smith family able to see through Roger's disguises, describing him as "the alien in the wig". Toshi has a sister named Akiko, who acts as a translator. Despite his apparent inability to speak English, his mother, father, and sister speak fluent English,. Toshi spoke English for the first time in the series in the episode "A Piñata Named Desire" after Snot angrily smacked him and demanded that he learn English. He attempted to say "Eat my balls!", but his heavy accent resulted in it sounding like "Eat my bowls!", which was reflected in the subtitles. He later sang part of "Yah Mo B There" by James Ingram and Michael McDonald on the episode "Home Wrecker". Additionally he briefly spoke English in the episode "Independent Movie" when he asked Steve, Snot, and Barry to leave him alone in a corn field during a soul searching session. Toshi also sings in English while part of the band B12 in season 8's "Can I Be Frank."
• Barry Robinson – Steve's morbidly obese friend, who has an inarticulate, strident, and sloppy vocal quality. Stan disdains Barry, often impulsively yelling insults at him about his weight without even knowing why. Like Snot, Barry can speak Klingon and seems to be able to read Quenya. Barry apparently has a fetish for Miss Piggy. His borderline mentally retarded and innocent personality is the result of powerful anti-psychotic pills. In "With Friends Like Steve's" after stopping his medication regimen, Barry turns into a deranged and demonic mastermind, speaking in a low-pitched voice "like Gary Oldman", framing Steve for the destruction of Stan's beloved commemorative plates. Barry did this in an attempt to replace Steve within his immediate family. Barry's madness grows worse over the episode, culminating with him trying to eliminate everyone that might get between himself and Stan. Steve ultimately tricks Barry into taking his medication, reverting him back to his usual self. This facet of his personality is hinted at when he helps Snot and Toshi beat up a drugged Steve and screams that they should kill Steve's whole family. Barry describes his parents as ignorant and implies that they engage in bondage sex play and smoke pot. Other statements about his parents imply that they abuse him or are negligent, making him sleep in their basement and often forgetting he is their son. He has a cameo appearance in the fat camp in the episode Killer Queen of the sitcom Family Guy.

  Other main characters

• Avery Bullock – The Deputy Director of the CIA's Langley Falls branch and Stan's 58-year-old boss. While significantly less paranoid and usually more competent, he is as high strung as Stan and, more often than not, is even less moral in his actions and authority. He had a brief relationship with Hayley Smith, which almost cost Stan his job until Hayley left Avery for her old boyfriend. He was married, but his wife Miriam was once held hostage in Fallujah where she was hand-cuffed to a radiator as he "does not negotiate with terrorists." She was later rescued by Stan, but was eventually killed by one of Roger's personas. Bullock prefers the company of younger, "plump Asian" women. Many jokes are built around Avery giving respected Shakespearean actor Patrick Stewart the most unlikely scenes and lines, such as a Seussian rhyme about all the things that can be purchased at a strip club, an energetic two-hour banjo session, singing "Little Girls" by Oingo Boingo while dressed in a woman's robe, and jokes referring to Stewart's prominent role as ' captain Jean-Luc Picard. A recurring joke is that Bullock runs the CIA like kindergarten, with time-outs, show-and-tell, snack time, and field trips. In "Bullocks to Stan", during the fight scene at the end of the episode, there is a joke referring to Star Trek, however, this is hidden by Klaus' commentary. Bullock appears in the Family Guy episode "Lois Kills Stewie" where he and Stan attempt to stop Stewie at gunpoint. The character is drawn identically to Stewart's appearance as himself on Family Guy.
• Principal Brian Lewis – The principal of Pearl Bailey High School which Steve and his friends attend. Portrayed as an aggressive borderline psychotic with a checkered past, he displays a multitude of violent tendencies and a flippant attitude, and his dedication to the school is questionable. When Steve is the Student Body President, he commandeers Principal Lewis' office, as the student body president is entitled to secure any school grounds he needs. Lewis does not mind, since in doing this Steve proves that he can read and that the system works. He later allows Stan to teach a "morally upright" sexual education class, but only Steve is signed up for it. Lewis is a member of the "Illuminutty" – an organization revolving around a supposed conspiracy involving the invention of peanut butter. When presented with a tip that Steve is in possession of narcotics, he displays detailed knowledge of the source and method of cutting said drugs, and concludes that a specific drug lord named Esteban Montilla is back in business and tells Steve to tell him that El Lobo Negrón sends his regards. He is the father of one of Lisa Silver's best friends, Janet, but rarely acknowledges this. When Steve asks him why he never mentions it, he says that he is "ashamed of her for more reasons than you can imagine". Lewis keeps $500 hanging out of his pocket to make the students think he is rich. Lewis has taken part in war reenactments, including a Vietnam War reenactment. In "100 A.D.", Principal Lewis is among the characters that pursue Hayley and Jeff for the bounty that Stan offers. In "You Debt Your Life", he explicitly states that he used to run cocaine. This statement is accidentally made over the school PA system. Lewis' questionable past is often the source of comedy and subplots for the show, such as when Lewis is shown to own an aquarium shop in addition to being a principal. Lewis' family was apparently the inspiration for the sitcom Diff'rent Strokes, with Brian Lewis himself being the inspiration for Arnold, according to the episode "The Worst Stan".
• Greg Corbin and Terry Bates''' are a gay couple who move to Stan's neighborhood in the second episode. Stan was completely unaware of the fact that his neighbors are a gay couple and while initially prejudiced against them for their practice of liberal journalism, he merely considered them nice young men that just happen to live together. He later discovers that they are gay and is initially prejudiced against them until he realizes that being straight is not a choice and accepts them both, sometimes referring to gay love as something even more exquisite than heterosexual love.

  Secondary characters

Smith family relatives

Stan's relatives

• Jack Smith – The abusive father of Stan, Rusty, and Nicholas Smith and the paternal grandfather of Steve and Hayley. For most of his life, Stan believed his father to be a secret agent but, in reality, he was a jewel thief. After the man Stan paid to pretend to be his father died, "Grandpa Smith" dropped in on the family. Roger developed a "boy crush" on Jack but the other family members were wary of him. Roger goes so far as to dress like him and keeps Francine locked in a cage because Jack put her in there. Jack has black hair, sports an eyepatch on his left eye, but otherwise resembles his son Stan. Roger compares him to Kurt Russell's character Snake Plissken from Escape from New York and Escape from L.A.. Jack's second appearance is a single line of him being heard but not seen in a flashback to Stan's childhood where he asks his father to read to him. Jack replies with a single line "Who the hell are you?" Jack makes his third appearance in a flashback showing him running out on Stan and his mother. Jack makes his fourth appearance in which Steve decides to visit him in his jail. When it is discovered that Stan never learned to ride a bicycle because his father was not there for him at the moments of need, Steve decides to reconcile them both by making Stan visit the jail where Jack is passing his sentence. After the latter one is released on Stan's parole, Klaus suggests the three of them should go camping as an act of reuniting Stan with his own father. It turns out to be a bad idea as Stan soon finds out that Jack is using his grandson to appeal to Stan so that he could defend his own father in court during the next trial verdict. Jack then turns Steve to his side and both run away, all while Steve begins viewing Jack as a father figure. When things get out of hand, however, Jack confesses that he is a crook who was up to no good all this time and wishes Stan would not lose Steve in times of need as much he himself once did. When Stan finds out about this, he forces himself to ride his bike to the courthouse to give his own word of reference about his father's verdict, but arrives too late, much to both Jack's and Steve's contempt. Jack is sentenced to five more years of prison, but is not bothered by the idea now that he has formed a genuine relationship with his grandson, and Stan promises to visit him this time. In "Blood Crieth Unto Heaven", it turned out that Jack had left the family after Stan found his mother making out with Jack and that he was eventually arrested after the police commissioner that Stan idolized and invited to his birthday called for police backup while investigating the thefts of the fruits from a fruit truck. In "Minstrel Krampus", Jack is revealed to have trapped Krampus while as a child. When Stan frees Krampus to teach Steve a lesson and it does not go well, Stan had to use his CIA connections to get Jack out of prison. After being shot by Santa Claus while protecting Stan Smith, the blood of Jack and Krampus combine which revives Jack as Krampus. In this form, Jack plans to continue his predecessor's job in tormenting naughty children. In the episode "Ninety North, Zero West," Jack Smith is still in his Krampus form as Stan persuades him to help save Steve from Santa Claus at the time when he plans to awaken the Sumerian giant Humbaba. In the episode "Klaustastrophe.tv", Jack reappears, now a human again. No explanation for this is given.
• Betty Smith – Jack's ex-wife, Stan's mother, and the paternal grandmother of Steve and Hayley. After Jack abandoned them, Stan took care of her and Betty began to depend unnaturally on her son. This relationship evolved to the point where Stan abducted all of Betty's new boyfriends from fear that they would end up hurting her, dumping them on an uncharted island. Betty later marries Hercules, a widowed Greek butcher, who she met through Francine. Betty tells Stan that neither she nor her son need to depend on one another as they once did, finally ending his obsessive protectiveness of her. Stan accepts that Betty has moved on and tolerates their marriage, though only after he has tried to stop them on board their flight to Greece. Betty is still unaware of her son's earlier actions, and all her previous suitors remain on a deserted island, which the two couples sail near after Betty and Hercules get married in Greece. A short time later, Hercules dies as well, once again leaving Betty as a widow. She moves back into Stan's house, living in the attic with a put-upon Roger, who goes by the alias of Tom Yabbo. She later falls in love with Roger and marries him. They take a trip to Niagara Falls where Betty plans to kill her new spouse, to collect the insurance money on a policy that she has taken out on him. Despite Stan's attempt to save his life, "Tom" falls to his death in the Falls, but Stan then notices Roger in a rain slicker leading a tour group, indicating he is fine. Betty manages to collect the insurance money and moves to Paris, France, where she is seen going into a theater to watch "Fast and the Furious 7" enjoying the gay sex scenes depicted.
• Rusty Smith – Stan's Native American half-brother who lives in Arizona with his wife Sooleawa'Uha and son Glen. He is the son of Jack Smith and a Cherokee woman he met in Santa Fe. Rusty and his family visit Stan's family every Thanksgiving. When their paternal grandfather was dying, he left Rusty and Stan $20,000 and some land he thought was worthless. Stan took the cash while Rusty takes the land, which turned out to have enormous copper deposits. During their annual reunions Stan treats his relatives in a patronizing way believing that they are poor. On a return visit to Arizona it becomes clear that earnings from copper mining have made Rusty the extremely wealthy owner of a desert estate, living in a huge mansion modeled on that of a Roman emperor. Humiliated and jealous Stan unsuccessfully attempts to steal the property only to be expelled by Rusty's security detail. Previously polished and courteous, the now-furious Rusty vows to kill his half-brother if he returns. After Hayley and Jeff rescue Stan, Francine, Steve, and Roger from the desert, Rusty appears with a gun stating that they are still on his property. When Stan asks how much land he has, Rusty states "sooooo much" in a dated and stereotyped Native American response. Rusty is distracted when the half-bodied helicopter pilot returns, giving the Smiths and Jeff the opportunity to escape.
• Sooleawa'Uha Smith – The Native American wife of Rusty and the paternal aunt of Steve and Hayley. She is also the sister in law to Stan and Francine Smith. Sooleawa'Uha patiently tolerates condescending remarks by Francine, although she lives in far greater affluence, with servants and a much larger kitchen.
• Glen Smith – The seldom speaking son of Rusty and Sooleawa'Uha and the paternal cousin of Steve and Hayley, the nephew of Stan and Francine Smith.

  Francine's relatives

• Bàba and Māma Ling – Francine's Chinese-American adoptive parents and the maternal grandparents of Steve and Hayley. Stan once found their ways of life and Mandarin linguistics to be unbearably obnoxious. This was especially because they practically took over his house and redecorated it in all of their original visits. However, after Baba saved Stan's life when his house was set on fire, he warmed up to the Lings and ultimately came to respect them. Bàba, in turn, apologized to Stan for not showing him more respect. In these moments, Baba also admitted he and Mama had been focusing most of their attention on their other daughter Gwen over Francine. They admitted to their belief that Stan was a decent son-in-law who has taken good care of her since they have been married. For this reason, both Baba and Mama know that it be unwise to give their money to Francine as opposed to Gwen when they pass away. Much of their behavior is a parody of Oriental stereotypes and are a mix of Chinese culture and Japanese. For example, bowing is a more pronounced characteristic of Japanese culture than Chinese, and their redecoration of the Smith house is in a Japanese style, complete with a kotatsu table. '
• Gwen Ling – Gwen is Francine's older sister, the biological child of the Lings. After Stan meets Francine's biological parents, he tries to manipulate Francine into wanting to meet them and disowning Baba and Mama. He accomplishes this by showing Francine their will in which everything is left to Gwen. At the episode's end, Baba reveals to Stan that it is Chinese customs to give the money to the child that needs the help and explains why they chose Gwen over Francine. He and Mama both know that she is an idiot and promiscuous. Gwen failed school when she was younger and therefore they know she will need a lot of help when they die. However unlike Gwen, Francine is smart, has a good husband, and she does not need their money. During an "expositional" joke, Gwen is implied to be three years younger than Francine, although she is actually three years older than Francine. It is implied that Baba and Mama both resent her for not being more like Francine. Stan apparently lusts after Gwen, who is repeatedly described as being "Playboy hot", which irritates Francine to no end as she and her parents know about her promiscuity. He has mused over a marriage between Gwen and either Greg or Terry. Francine talks Stan out of this, citing the fact that Greg and Terry are obviously homosexual and are not interested in getting involved with her sister. Stan does not immediately accept this, preferring to believe that Gwen is "too hot" for either man, but he eventually comes to terms with and accepts their homosexuality. Gwen makes her first on-screen appearance in "Now and Gwen" when she visits the family as a cover for her probation officer and continue her scams. Hayley gets annoyed with Francine always covering her and finally confronts Gwen, receiving a vague warning. When she tells Francine, she discovers that Gwen took the blame for a school fire started when Francine tried to emulate her sister's smoking in school and had tried to make up for it ever since. As a result of Hayley's confrontation, she planned on setting the school on fire and frame Francine for it. With Gwen admitting that she took the blame the first time due to her love for her sister, they work out their differences. Gwen offers Francine a cigarette to celebrate patching things up, but the two accidentally set the school on fire. Francine agrees to take the blame and be arrested. Gwen however gets arrested for violating her parole while Francine's charges are dismissed under a suspended sentence due to Stan's connections to the CIA. As a result, Gwen promises revenge against her sister once she gets out of prison.
• Nicholas and Cassandra Dawson – Francine's biological parents who are also the parents of Janet. They abandoned Francine as an infant just to fly first class, since they could not do so with her. They are wealthy and appear good-natured, but deep down they are extremely self-centered. Stan once befriended them and tried to introduce them to Francine, by inviting them in the house. When the Dawsons admitted that they gave her up just to keep their first class ticket, this made Stan nervous around them, but is determined to keep them around. However, Klaus sees both Nicholas and Cassandra for who they truly are and warns Stan to get them out of the house because he is setting Francine up to be hurt by them. He tried to ignore Klaus, but eventually realizes that he was right about the Dawsons. Stan stopped trying after being put off by their selfish nature, especially when they leave him trapped in his burning house instead of helping him out, feeling she is better off not knowing about them. They leave without meeting her. In the episode "Family Plan," Francine officially meets Nicholas when she decides to be part of a bigger family. By this time, Cassandra had committed suicide by hanging and Nicholas has pitted the family against each other in order to see who gains control over the family fortune. After Francine is the left the victor, he tries to finish off her as well, only for Stan to save her. Nicholas is left alone with only his cat.
• Janet''' - Francine's cousin through Nicholas and Cassandra. Apart from Nicholas, she is the only member of Francine's biological family that is still alive.

  Fischer family

• Henry Fischer – Father of Jeff, who grows and deals marijuana in Raleigh, North Carolina. He has used Jeff to ship drugs, which has gotten Jeff framed for drug-trafficking. When Stan and Roger learn that Jeff is wanted on drug charges in Florida, they pursue him to his father's farm hoping to cash in on the reward and get Jeff out of Stan's life. They are tricked and tied up by Henry who declares that he intends to turn in Jeff himself for the reward money. He also reveals a startling fact that he had grown the marijuana Jeff was found with on his farm and sent Jeff to bring it to Florida, though Jeff had been totally unaware of any of this. Stan and Roger escape but Mr. Fischer has already turned Jeff in at the Boca Raton Police Department, and openly admits that he cares more about the money than his son. Stan, however, proves Mr. Fischer's guilt, because he had been wearing a wire during his confession as he always wears a wire for his job. Mr. Fischer is taken away for the drug charge and for attempting to murder Roger and Stan. Henry later popped up as an audience member in "Phantom of the Telethon".

  Corbin-Bates family

• Greg Corbin – The local news anchor on W-ANG-TV, he is Terry's brown-haired co-anchor and domestic partner. He along with Terry are neighbors to the Smiths. He and Terry have a penchant for minor bickering, flirting, and working on stereotypical "couples' issues" on the set or in other scenes of the show. Greg is a member of the Log Cabin Republicans. He is presented as being very culturally sophisticated, at one point causing Stan to choose him over Francine as his guest to get into Avery Bullock's high-end party. He and Terry have a surrogate baby daughter, Liberty Belle. Before Libby's birth, Greg is panicky, questioning his ability and readiness to be a father, but immediately loves Libby upon holding her for the first time. He is the "power top" in his and Terry's relationship and was once involved in a heterosexual marriage, during a period of time in which he was "confused" and believed he was heterosexual.
• Terry Bates – Terry Bates is a Langley Falls local news anchor, Greg's co-anchor and domestic partner, and the Smiths' neighbor. Terry is a Democrat with blonde hair. He once goes out for a night with Stan as Stan erroneously attempts to "become gay" by choice, though they stop short of having sex when Stan realizes that he cannot choose to be gay. He has a surrogate daughter with Greg—Liberty Belle—and owns a French bulldog named "Heath Ledger". He is the bottom in their relationship. Another strain on his relationship with Greg was when Greg was revealed to be a Log Cabin Republican, to which Terry threw a tantrum in front of the whole neighborhood in disbelief at how Greg could have voted for George W. Bush. Terry eventually leaves Greg to follow the band 311 around. Terry's removal from the series was due to Mike Barker leaving the show due to creative differences.
• Liberty Belle "Libby" Corbin-Bates – Terry and Greg's daughter, conceived with an egg donor and Francine as a surrogate mother. Shortly after her birth, Stan kidnapped her because he believed that gay couples should not be allowed to raise children; they nearly reached Nebraska but Stan was finally convinced to return her to Greg and Terry. Stan had named her after the Liberty Bell where her dads kept the name, but barred him from seeing Libby again for his actions.
• Tank Bates – Tank is Terry's father and a retired Washington Redskins player. In early episodes, Terry is implied to be closeted from his father, stating, "I've told you, as soon as my father dies I will wear the ring", upsetting Greg, who believes Terry should stop hiding their relationship. When "Tank" comes to visit, Terry pretends that Francine is his girlfriend and that Libby is their illegitimate daughter, and claims that Stan and Greg are gay lovers. During the time he spent in the episode, Tank is shown to be quite intolerant of homosexuality, constantly mocking Stan and calling him "fairy". When Stan drunkenly outs Terry, Tank disowns his son. After unsuccessful attempts by Stan to decipher the basis of Tank's homophobia, Terry eventually gives his father the option of accepting him and being a part of their family or leaving, with Tank choosing to disown him. Tank later participates in a Vietnam War reenactment in the episode "In Country...Club", but has no dialogue. In "Gorillas in the Mist," Tank was shown watching the news in a bar, where Terry mentions that he forgives his dad. Tank changes the channel and tells the bartender that the guy dancing on television is his son. In "The Two Hundred," Tank Bates appears as one of the savage survivors.

  CIA personnel

• Jackson – One of Stan's co-workers at the CIA. He was once a real estate agent, and is a "former homosexual". Apparently, when he stopped selling houses, his "sodomy cleared right up." His conversion has been suggested to be unsuccessful, suggesting that he may be transgender as well. Moreover, when asked if he ever "did it with a dead mermaid," he replied "Mermaid, no." He had a body double who was accidentally killed by Stan. He is almost always seen with something in his hands, such as a coffee cup.
• Dick Reynolds – Another of Stan's CIA co-workers. His wife eventually got a job in which she earned more money than he did, eventually surpassing him so much in earning power that his genitals disappeared, a joke referencing his sense of emasculation. He has a son who has a freakishly large hand with which he beats his father. He is now divorced from his wife Sheila and has a dog named Biscuit, which he seized from Sheila when he was angry that the courts awarded ownership of the dog to her during their divorce. In "One Little Word", Stan and Bullock unknowingly encounter Dick dressed as an automobile at a furry convention and seen "running over" a furry. He is later seen still running over an unconscious Roger but stop when he gets a call on his cellphone.
• Reginald the Koala – Like Klaus, Reginald is an animal with the brain of a human. Differently however, he is a koala with very urban mannerisms and behaviors. His first appearance was in "Family Affair" where he was revealed to have been a homeless man at one point who, in exchange for a free hot meal, chose to partake in a CIA experiment that had his brain put into the body of a koala. The lyrics of an '80s theme song played in the episode imply that he uses his new adorable body to go on missions, able to distract the enemy with his cute koala body such that no one would question him. In the episode "Wife Insurance," it is shown that he goes on dangerous missions like Stan and the others. He is regularly seen relaxing in Stan's pool. Reginald has dated Hayley. Reginald is also skilled in the Afro-Brazilian martial art known as Capoeira and has used it to fight Bullock over Hayley.
• John Sanders – Another of Stan's CIA co-workers. He often takes part in meetings with Bullock and Stan. He goes out with Jackson and Dick and once killed a panda.
• Ray – A CIA agent and one of Stan's poker buddies alongside Bad Larry. Ray always recalls what he ate after he killed someone. In "Office Spaceman," Ray is among the CIA Agents on the CIA's Alien Task Force. In 100 A.D., Ray died in a bus crash with the other background characters that wanted the bounty that Stan offered for the capture of Hayley and Jeff. He has since turned up alive. In "Old Stan in the Mountain," Stan mocks his age to persuade Bullock that he should replace him in the demonstration of a high-tech killing machine. But Stan is cursed by another old man that he had mocked and is rapidly aged to even older than Ray. The demonstration is a disaster, much to Ray's delight as Avery asks if this was a way to mock him.
• Bad Larry – A CIA agent. He recalls his first kill where he shot his ex-partner who was a double-agent. He helps Ray and Roger get Stan his first kill—a pedophile named Randy—whom they trail to the "Wet, Young & Wild" water park. When Randy brags that he will get off due to his mother's money and a good lawyer, Stan fires his gun and accidentally shoots Bad Larry. He also appears in "Tearjerker" and "Widowmaker."
• Duper – Agent Duper was a CIA Agent and rival of Stan Smith who first appeared in "Roger Codger". He beats Stan's time on a "Regime Change" testing simulation following with a better snappy line than Stan's. When Stan placed a bomb in Bullock's office to make himself look good by saving the day, Duper disabled it when Stan could not see the manual. In a later episode, his essay on President Bush beat Stan's, but he was disqualified after learning most of his essay was plagiarized from Willy Wonka. In 100 A.D., Duper and Ray died in a bus crash with the other background characters that wanted the bounty that Stan offered for the capture of Hayley and Jeff. In "Son of Stan", Duper appears to be mourning himself, but it is actually a clone the CIA made. The clone is exactly the same as Duper. This inspired Stan to clone Steve for a parenting experiment. Later in the series, Duper suffers from the effect of a time-travel experiment gone wrong. Since he failed to return to the present before midnight, he returned as a blob of what used to be flesh. In "Honey, I'm Homeland," Duper took part in Avery Bullock's activity to test Mount Rushmore's defenses by posing as Christoff of the Occupy cell. In "She Swill Survive," Duper is on Bullock's list of people who like crocs.
• Bill – Bill is Stan's CIA double. The only noticeable difference between the two is Bill's southern accent; and he can easily impersonate Stan's voice. He often takes Stan's place when there are things he does not want to go to, such as Steve's baptism or cooking classes with Francine. When Stan was faced with the dilemma of whether to go to the high school reunion prom with Betty Sue, the Homecoming Queen and saving his marriage with Francine in "It's Good to Be Queen", Stan called in Bill to take Francine out to dinner while he went to the prom. But soon Francine decided to go to the prom, making things a bit complicated, since Stan decided to give up his dream rather than lose his wife. When the two of them were standing in the same gym, Francine took Stan's gun, preparing to shoot his leg. She ends up shooting the one who did not apologize, who was actually Bill. Bill was taken aboard a helicopter, hearing that his leg cannot be saved. In "Pulling Double Booty", Hayley meets Bill after going to the CIA to have an Argument with Stan. Mistaking Bill for Stan she apologizes which leads to them getting into a relationship. When Bill is shown by Stan how "hot" Francine is, Bill tries to have sex with Francine by impersonating Stan. Stan throws Bill out of the window, by what appears to be his genitals, and tells Bill that he cannot see Hayley again. In order to stop Hayley going on a rampage when Bill dumps her, Stan pretends to be Bill to take Hayley out on a date.
• Lorraine – Lorraine is the obese secretary of CIA Headquarters. She first appears in "Chimdale" in which Steve shows her the bald eagle balloon that he brought for his dad whom he believes is working without his wig but finds out he is still wearing it. Lorraine has a crowd scene cameo after Jeff claims the money in "100 A.D.". In "G-String Circus", Deputy Director Bullock directs her to send a mass e-mail to all agents to join him at XanaBoobs to spend the CIA surplus funds. Lorraine becomes Deputy Director Bullock's personal assistant in "Flirting With Disaster". When Francine is hired to replace her as secretary, all of the CIA employees start paying attention to Francine and ignore Lorraine. During lunch with Stan who is also depressed that he feels he cannot flirt with the office ladies while Francine is around, the both agree that Francine has to go. While Stan merely wants to get Francine fired, Lorraine throws acid in Francine's face, melting it and is arrested. Despite her previous legal problems, she is seen as a secretary again in "Wheels & the Legman and the Case of Grandpa's Key" when she enlists the help of the duo to locate her missing bird Flygirl which is already dead and Steve struggles to hide the body until he learns to confront people with bad news and tells her the truth. Lorraine appears in "The Missing Kink" during the "He's Got a Kink" song in which she is seen sitting on a man wearing a green S&M suit while another man in an orange S&M suit stands by wearing a lamp shade over his head.

  Pearl Bailey High School

• Akiko Yoshida – Akiko is Toshi's younger sister. She first appears in "American Dream Factory" as a child with no dialogue when Toshi brings her to audition as a drummer for Steve's Band "The Asstones" but on her next appearance in "Weiner of Our Discontent", she is a pre-teen or young teenager. She refereed the hot dog eating contest between Toshi and Steve in the same episode. She speaks perfect English and occasionally translates for Toshi. Akiko dressed as Chun-Li from the video game series Street Fighter for Halloween in "Best Little Horror House in Langley Falls". When Steve develops a crush on Akiko, they are forced to flee from Toshi until Steve convinces him that he is being too possessive of her. Thinking he can open up to Akiko, Steve is stunned when she announces she has a crush on a nine-year-old named Doug because he is a great dancer; however, in a later episode "Spelling Bee My Baby", Akiko developed feelings for Steve and vice versa.
• Debbie Hyman – An overweight goth girl and Steve's main crush. When she and Steve begin dating it causes Stan to become anorexic because he is disgusted by her obesity. Steve breaks up with her after he realizes she is causing it, but they reunite when he realizes it did not help.

In "", Roger states that Linda has died.

In "Best Little Horror House in Langley Falls," it was revealed that Buckle used to work as a Walt Disney Imagineer until his designs were deemed too scary.

In "Rapture's Delight," when everyone is ascending into Heaven, Father Donovan is left behind with Roger, Stan, and Francine, at which point he remarks, "Turns out there is a God".

In "Season's Beatings," Father Donovan casts Stan and Roger in a televised Christmas play at the mall, but when they break out brawling during a performance, he bans Stan from the church on his superiors' behalf with the only way of re-admittance being either donating a lot of money to the church, finding the Holy Grail, or killing the Anti-Christ. When Stan realizes that the baby Hayley and Jeff took in and named Nemo is the Anti-Christ, Stan was able to present evidence of this to Father Donovan causing them, with Roger and Jeff, to pursue and kill Nemo.
