List of That '70s and '90s Show characters

• Angie Barnett (played by Megalyn Echikunwoke) is Hyde's half-sister. Hyde did not know he had a sister until season 7. Angie graduated from college as a mathematics major. Angie and Hyde worked together managing their father's record store, but Angie did not always like working with him. She dated Kelso, which sometimes annoyed Hyde. Angie got her name because all season 7 episodes were named after Rolling Stones songs, and "Angie" was a song by the Stones.
• Annette Berkardt (played by Jessica Simpson) was Kelso's girlfriend for a brief period of time in season 5. She acts and talks very similar to Jackie, constantly bossing Kelso around. Eric and Donna once referred to her as a blonde version of Jackie, or "Blackie." Despite this, Jackie and Annette hated each other. Once at The Hub, Jackie said to Annette "I did not know they let 'slutballs' in here". Annette said since she saw Jackie in there she thought it was okay. Later in the episode, when Annette and Kelso were kissing, Jackie yelled "Get off my boyfriend!" to Annette, even though it was months after Kelso and Jackie broke up. This led to Hyde wanting to break up with Jackie. After Hyde and Jackie both reconciled and seeing Kelso is still not over Jackie, Annette decides to break up with Kelso and go back home to California.
• Beatrice "Bea" Sigurdson (played by Betty White) is Kitty's mother. Bea seems like a friendly old lady but is cold and critical, especially of Kitty. She appeared in a few episodes in season five, often nagging at Burt or saying something rude to Kitty in a faux-friendly manner. She was widowed in "Your Time is Gonna Come" when Burt collapses in the driveway and is rushed to the hospital where he dies. She shows little emotion after her husband's death but Kitty does catch her crying in a bedroom. Bea stays with the Formans for a while after Burt's death, causing Kitty considerable stress. She is mentioned as being deceased by the time of the first episode of That 90s Show. In the seventh episode of That 90s Show, Kitty mentions that they spread Bea's ashes outside a Sizzler restaurant.
• Bernice Forman (played by Marion Ross) is Red's mother. Bernice resented Kitty and was always mean to her. Kitty revealed it was because Red married her instead of an attractive and wealthy woman he once dated who Bernice liked. She appeared in the episodes "Sunday, Bloody Sunday", "The Best Christmas Ever" and "Grandma's Dead" of season 1, and in a flashback in the episode "Halloween" of season two. In the episode "Grandma's Dead" she dies in Eric's car while he is driving her home after Eric tells her off for her treatment of his mother.
• Brooke Rockwell (played by Shannon Elizabeth) was the valedictorian of the high school class two years before Eric's class. The summer after Kelso's graduation, she had sex with him at a Molly Hatchet concert in a bathroom stall and got pregnant. Initially, Brooke did not trust Kelso because of his immaturity and did not want him in the child's life. Eventually, Kelso convinced her to give him another chance. Brooke gave birth to their daughter Betsy in 1979.
• Burt Sigurdson (played by Tom Poston) is Kitty's father. He is often seen avoiding his wife, Bea. In one episode, he bought an ostrich farm, which was right next to a coyote farm. The coyotes ate all the ostriches and the Sigurdsons had to sell the house. Burt died in the driveway on the episode "Your Time is Gonna Come". He is later mentioned in the eighth episode of "That 90s Show" to have given Kitty beer when she was ten.
• Caroline "Crazy Caroline" Dupree (played by Allison Munn) was Fez's girlfriend in season 3. Fez quickly learned Caroline is very jealous and paranoid. She made threats against Donna and Jackie because Caroline felt they were going to steal Fez from her, when in fact Jackie and Donna had no intention of doing so. Caroline was once found hiding in the men's bathroom looking for Fez. Fez did not want to be with someone that aggressive and paranoid so he broke up with her. Fez and Caroline were together one last time in the eighth season. She got extremely angry when she found out that Fez had lied to her about Jackie being his roommate, and when she found nude photos of Donna in Fez's Barry White album (Leo hid the nude photos in the album without Fez's knowledge, but Caroline believed they were put there by Fez). Caroline appeared again in "Sheer Heart Attack". Fez was having sex with women once and not seeing them again and then decided that he wanted to be with only one woman, so he called Caroline. Later in the episode, Jackie told Fez that she loved him and then kissed him as Caroline walked in. This, as always, made Caroline angry with Fez and attack him viciously.
• Casey Kelso (played by Luke Wilson) is Kelso's brother who was in the military. Towards the end of season 4 he was dating Donna. During their relationship, there were instances of them engaging in bad behavior, such as Donna drinking and skipping school to hang out with Casey. Donna's father, Bob, felt that Casey was a bad influence and did not want Donna to date him anymore. Eric was jealous of Casey because he wanted to be with Donna, so Eric wanted them to break up. When Red, Kitty and Bob were discussing Casey's bad influence with Donna and Casey, Casey broke up with Donna, deciding the conflict with the adults to be too much hassle. Donna felt that she and Casey were in love, but Casey cruelly said "I have this thing where I say stuff don't really mean." Kelso said that his brother got bored with his girlfriends and broke up with them. During the summer of 1979, Casey was teaching physical education at Eric's old high school, and Eric was in Casey's class. He likes to call Eric "Foreplay". His last appearance was in the Season 7 episode "2120 So. Michigan Ave". He is later mentioned in the season finale of "That 90s Show" when Donna tells Leia she dated him while broken up with Eric.
• Charlie Richardson (played by Bret Harrison) is the son of one of Red's war buddies. Eric held a grudge against him from the time that he let some sick children win "Eric's" goldfish in an egg toss. Charlie only appeared in about three episodes towards the end of season 7. Before the beginning of season 8, Charlie accidentally fell off the water tower and died. The water tower is named the Charlie Richardson Memorial Water Tower in his honor. The show originally planned to have Charlie stay the entire 8th season as a replacement for Eric, but killed Charlie off because Harrison got an offer to star in The Loop.
• Christine St. George (played by Mary Tyler Moore) is a talk show host of What's Up Wisconsin. In the episode "Sweet Lady", Jackie felt she was destined to be Christine's co-host on the show. She persistently tries to get the job, but Christine St. George makes Jackie her assistant instead. After a few episodes, Jackie was fired for knowing too much about her.
• Earl Arthur (played by Bob Clendenin) is a friend of Red's who worked for Red at Price Mart. Earl frequently came to work late and slacked off on his job, so Red fired him. In response Earl sued Red for wrongful termination, but the judge ruled in favor of Red when Earl arrived too late for his own hearing. Earl later got a job working at a fast food restaurant, where he is again fired for his poor work ethic (this time for repeatedly eating the restaurant's food while at work). Earl appears in the episodes "Red Fired Up", "Roller Disco" and "Radio Daze".
• Edna Hyde (played by Katey Sagal) is Hyde's biological mother. She is in the season 1 episodes "Career Day", "Prom Night", and "Punk Chick", only appearing on-screen in "Career Day". She plays a large part in "Career Day" as the school chef "Gross Edna", playing opposite Hyde when he has to help her in the kitchen on Career Day. In other episodes she only has lines yelling at Hyde on the porch from the inside of the house such as:
  • In Prom Night Edna: "They're all gonna laugh at you!" (a prom night reference to the 1976 film, Carrie) Steven: "Shut up ma, you're makin' the night too damn special!"
  • In Punk Chick Steven: "It's still my suitcase!" Edna: "Nothing in this house is yours!" Steven: "Shut up!"

Edna then ran off and abandoned Hyde, not heard of again until the 4th season where Hyde claims that she and his stepfather Bud got back together and ran off. After Hyde's abandonment, Kitty prevailed upon Red to let the squalor-ridden Hyde live with the Formans.

• Fenton (played by Jim Rash) is someone with whom Fez has a feud due to a "half-off sale, a crowded parking lot and a pair of pants that made Fez's ass look like an oil painting" (in Fez's own words). In the fifth season, he was an employee at the jewelry store where Eric bought Donna's engagement ring. He is also the landlord of the apartment that Fez and Kelso moved into in the seventh season, which later became Fez and Jackie's apartment when Kelso moved to Chicago. At first, Fenton did not want to let Kelso and Fez move in because of his feud with Fez, but later when he found out Kelso wanted the apartment to have a place to take care of his daughter, and Fenton got the impression that Kelso and Fez were "life partners", he let them have it. Though Fenton does not state this explicitly, his frequent innuendos about men, his lack of experience with women, his mannerisms and affect overtly imply that he is gay. Whenever he sees Fez, he says "Oh, it's you" in a contemptuous way. Neither Fenton nor Fez specifically explain the reason for their mutual hostility and dislike to Eric, despite his increasing curiosity. Fenton later becomes good friends with Jackie, who persuades him not to evict Fez and end their feud. However, very shortly thereafter she carelessly floods both their apartment and Fenton's apartment directly underneath after falling asleep while running the bathtub. He returns in the finale of "That 90s Show," now Sherri's landlord, and reignites his rivalry with Fez. He also mentions that he now owns three houses, a duplex and a Dippin Dots. He is the only character who was not part of the main cast to make an appearance in "That 90s Show".
• Hilary Robinson (played by Lara Everly) is Fez's co-worker at the salon where Fez works in season 8. Fez tries to impress her by trying to look cool, which instead intimidates her. However, when Jackie explains to her who Fez really is, she falls in love with him. Fez and Hilary date for a few weeks before Hilary suddenly decides to become a nun and leaves Fez.
• Jack Burkhart (played by Paul Kreppel) is the father of Jackie. Jack's imprisonment for bribery and embezzlement causes Jackie to cease being a rich, privileged girl.
• Joanne Stupac (played by Mo Gaffney) is a girlfriend of Bob who appears in seasons 4 and 5. She meets Bob at the supermarket when Bob, unable to cook, was about to buy a dozen TV dinners. Joanne decides to teach Bob to make a meatloaf so he would not have to buy more TV dinners. She does not get along well with Red. When Red and Joanne first meet, they get into an argument about who would cook the meat and who would make the salad. Joanne works at the dog food factory and hires Eric to put coupons in the dog food bags. Eric eventually loses that job after Joanne breaks up with Bob.
• Mitch Miller (played by Seth Green) is a student in the same class as Eric. Mitch has a feud with Fez and publishes a photo in the school newspaper of Fez and Kelso kissing each other. Mitch has a crush on Donna, and the two once went to a wedding. Eric is angered when Mitch embarrasses Donna, and Eric and Mitch agree to fight each other the next day at 5:15 PM. Not wanting to fight, Mitch persuades Eric not to fight by offering him a French-made GI Joe called "GI Jacques". Mitch has a father, Charlie Miller, played by Fred Willard.
• Nina Bartell (played by Joanna Canton) is a girlfriend of Fez in season 5 who works with him at the DMV. Fez loses his virginity to her but it goes badly, so she suggests they need to do it more often to get better. It turns out that the reason she's dating Fez was to anger her parents due to him being "different", They break up a while later because Nina thinks he is too needy.
• Officer Kennedy (played by James Avery) is Kelso's training officer when he joins the police force. He appears mostly in the 6th season, playing a straight ace to the bumbling Kelso.
• Pam Burkhart (played by Eve Plumb in season 1 and Brooke Shields in season 6) is the mother of Jackie who was dating Bob Pinciotti in season 6. Once a serious business lady, she flees to Mexico when Jackie's councilman father is arrested for bribery and embezzling $60,000. She returns to try to fix her relationship with Jackie.
• Pam Macy (played by Jennifer Lyons) is a classmate of the main characters of the show. She is mentioned in more episodes than she appears, mostly by Michael Kelso. She appears in the episodes "Prom Night", "Romantic Weekend", and "It's a Wonderful life". In "Prom Night", Michael takes Pam to the prom while temporarily broken up with Jackie. In "Romantic Weekend", Kelso is about to have sex with Pam but is unable to perform, telling his friends "the buffer wouldn't buff." Pam tells the whole school, which causes everyone to tease Kelso.
• Pastor Dave (played by Kevin McDonald), Pastor Dave is the local pastor at the church. He is overly cheerful and (incorrectly) thinks he is "hip cand cool", up to date with the trends. He is often greeted by Eric and his friends with deadpan voices, and they typically just agree with Dave in the hopes he'll go away. Dave is good friends with Kitty, who helps with the church fundraisers, and has an uneasy friendship with Red (mostly because Red is not used to having friends). His friendship with Red seems to have brought out a less-pure side of Dave, as he spends a day with Red watching football and drinking beer, and once even quit the church because he wanted to watch more football on Sundays (later rejoining as the pastor). He appears primarily in season 3 and 4, but has a few cameos in season 2.
• Rhonda Tate (played by Cynthia Lamontagne) Often called "Big Rhonda" by her classmates, she is a recurring character during season 4 as Fez's girlfriend. When she and Fez are stuck in the school during a tornado they are about to have sex, but Rhonda changes her mind when the tornado ends. She breaks up with Fez after she chokes him after he wanted to get to third base, which came from bad advice from Casey Kelso. Like Fez, she loves candy. She treats Eric with relentless contempt but is genuinely fond of Fez. She also physically intimidated tiny Jackie by threatening to wrestle her after Jackie gets rude with her. The episode "It's a Wonderful Life" features an alternate timeline where Rhonda goes to the prom with Eric (in this timeline, Eric and Donna were never in a relationship), and they remain together until he dumps her. Eric mentions that the two only had sex three times. Later in the same episode she is seen at their 10-year reunion but now as a trim, beautiful, and sexy woman. Rhonda claims her new body came from being dumped by Eric, leading her to lose weight using Jane Fonda workout tapes before becoming a fitness instructor herself. She thanks him for this. It is also mentioned in the season 3 episode "Kitty's Birthday" that she was hit by a car but was apparently uninjured.
• Roy Keene (played by Jim Gaffigan) is the kitchen manager of the Holiday Hotel employing Eric, Hyde, and Kelso to work as waiters in the hotel's restaurant during seasons 5 and 6. The character serves as the replacement for Leo, who was written out during season 5. Hyde mentions that Roy is like a father figure since his father abandoned him. Roy has stated that his standards for food service are low, and he goes days without washing his hands. Roy served in the Vietnam War, once describing Eric as "scrawny, but strong... like the Vietcong". He suffers from serious trouble connecting to people. One time, he got the impression a woman was in love with him after she insulted him when he got her some butter, so he hid in her shower to surprise her with flowers. He once mentioned he was living with a woman but moved out when she found out he was living with her in secret. It is revealed in the season 6 episode "A Legal Matter" that he was a police cadet who was kicked out of the police academy for shooting a police horse.
• Samantha Hyde (played by Judy Tylor) is Hyde's wife during season 8. They got married while Hyde was drunk in Las Vegas. The two barely knew each other when they got married. Hyde did not even remember the wedding and did not know he was married until after Samantha came to Point Place to see Hyde. In the episode "My Fairy King", Hyde learned that Samantha was already married to someone else. After this, Hyde and Samantha's relationship ended.
• Schatzi is a Dachshund that Red gave Kitty in an attempt to make her happy. Schatzi was in several episodes of season 5, was absent for all of season 6, then returned for only one episode towards the beginning of season 7. Red claimed that his absence was due to hiding under the house because he was afraid of the garden hose. "Schatzi" is German and means "little treasure" or "darling" (diminutive of "Schatz"). In the eighth episode of "That 90s Show", Kitty mentions that they don't have a dog anymore, confirming that Schatzi is either dead or no longer lives with the Formans.
• Steven James "Bud" Hyde Sr. (played by Robert Hays) is Hyde's stepfather. Bud Hyde worked as a bartender and is an alcoholic. Until the end of the 6th season, Hyde thought Bud was his biological father. Bud abandoned Hyde when he was a child and Steven was always angry at Bud for this. They temporarily reconciled in season 3, with Hyde even moving in with him. However, he would leave again at the beginning of season 4 after getting back together with Edna – forcing Hyde to move back to the Forman house. Hyde mentioned that Bud did attempt to get in touch with him again. (Bud was passed out drunk on Hyde's car.)
• Suzy Simpson (played by Alyson Hannigan) appears in two episodes of season 6. She is Kelso's buddy from the police academy who is also attracted to him. Fez has a crush on Suzy and it is because of her that he and Kelso fight after Kelso lies to Fez saying that Suzy has agreed to go on a date with him when really she thinks that she is dating Kelso. However, when Fez reveals that Kelso's having a Baby with another woman and Kelso reveals that Fez is married, she is furious and wants nothing to do with them.
• Timmy Thompson (played by Paul Connor) is an annoying fellow student in the gang who always embarrasses someone with loud comments meant for everyone around to hear, such as:
  • "Heeey, Forman and Donna got a motel room and they're going to do it!"
  • "Heeey, I'm taking off my pants!"
  • "Heeey, Forman's on a date with his mom!"
  • "Heeey, Donna's showed her ass!" (while showing everyone a yearbook photo where Donna mooned the camera).

He only has real dialogue in the episode "Burning Down The House".

• William James "WB" Barnett (played by Tim Reid) is Hyde's biological father. Hyde originally thought Bud Hyde was his biological father until the cliffhanger between the 6th and 7th seasons, where Kitty discovers that Hyde's real father is a man who lives in Milwaukee. Sometimes people call Barnett by his initials, "WB". Barnett is wealthy and owns Grooves, a chain of record stores. Barnett put Hyde in charge of the Point Place record store along with his daughter (and Hyde's half sister), Angie. Barnett is an African American, which Hyde believes explains his "coolness, afro and suspicion of The Man" (it can also be noted that when Hyde asked him who killed Kennedy his father stated "I don't know, because they don't want me to know"). WB's last on-screen appearance is in the first half of the series finale which is the twenty-first episode of the eighth season, "Love of My Life" (WB had already appeared in the fourteenth episode of that season, "Son and Daughter").

• Sherri Runck (played by Andrea Anders) is the single mother of Gwen and Nate Runck, with different men. It is stated that Nate's father lives and works in Japan, where he plays baseball and does commercials for adult diapers, as the oldest player on the team, and Gwen's father is a trucker who sometimes passes through Point Place. She lives in the house next door to Red and Kitty, which she is revealed in the season finale to be renting from Fenton. She had a tendency to sleep with a lot of men before the show, but has a relationship with Fez in the show, which she tries to give up to focus on herself. She befriends Red and Kitty, and is also shown to have issues with her deceased father. In "Boyfriend Day One" it is shown that she does not know how to ride a bike.

Several characters on the series were written as recurring, but made only one appearance. Among them:

• Tina Pinciotti (played by Amanda Fuller) is the younger sister of Donna. She first appears in "Eric's Burger Job", but make no following appearances aside from a brief mention in the Soap parody in "Vanstock". She is later written out with no explanation, as demonstrated in the season 7 premiere when Kitty refers to Donna as Bob and Midge's only child.
• Valerie Pinciotti is the older never-seen sister of Donna and Tina Pinciotti, who was said to be away at college in "Eric's Birthday" and never mentioned again.
• Matthew and Rebecca Erdman (played by Kevin Farley and Shannon Holt) are the prudish, fundamentalist host parents of Fez. They first appear in "Drive-In" and convince Fez the rock music they detest is diabolical by playing a KISS album backwards. Although referenced several times, Fez's host parents make no further appearances in the show. They eventually kick Fez out of their home and take all his money as back rent because he graduated a year ago in season 7.
• Buddy Morgan (played by Joseph Gordon-Levitt) is introduced in "Eric's Buddy" and was intended to become a recurring character. However, the introduction of a homosexual as a love interest for Eric (at a time when both Eric and Hyde were competing for Donna) did not go over well with audiences, and Buddy was cut from the show.
• Melissa (played by Reagan Gomez-Preston) appears in "Hyde Gets the Girl" as a potential love interest for Hyde. She was intended to become his on-off girlfriend.
• Patty (played by Lindsay Sloane) appears in two episodes in the season 2. She is introduced in "Eric Gets Suspended" along with her best friend, Mary (played by Melissa Joan Hart). The two go on a double blind date with Hyde and Fez. Hyde initially pairs with Mary, and Fez with Patty. However, in the course of the date Hyde tells Fez to swap dates, because he is hitting it off with Patty. Patty then returns in "Eric and Kitty's Night Out", becoming Fez's girlfriend. Patty's role and impact in the episode implies an intention to continue the character's appearance in the series, but Patty is not seen or mentioned again.
