Portrayed by Roseanne Barr
- All Bikers Are Hells Angels: A pretty noticeable aversion. Dan is a nice guy who works an honest nine-to-five job but loves the Harley he's had since high school and was so big into biker culture that he actually owned and ran a shop repairing and selling restored classic bikes.
Mark: (Seeing Dan's Harley for the first time) Nice bike. Ever think about selling it?
Dan: Actually, I was planning on being buried with it.
- Anyone Can Die: Dan, revealed in the final episode he really did die from his heart attack. All episodes from that point onward were just fantasies dreamt up by Roseanne for her book.
- Big Beautiful Man: Dan tends to attract women who explicitly gush about how handsome and sexy he is in addition to being such a nice guy. To say Roseanne is unhappy with this would be an understatement.
- Big Brother-In-Law Instinct: Do not abuse Jackie. He may be less dangerous than Roseanne, but he's not a threat to be taken lightly.
- He may actually be more. Roseanne will just kill you, Dan will hurt you. Repeatedly.
- The Big Guy
- Henpecked Husband: At times.
- Oedipus Rex: Dan has very serious, unresolved issues with his father throughout the show's run. It doesn't help when Conner Sr. marries one of Roseanne's friends and has a kid with her.
- Only Sane Man
- Overprotective Dad
- Papa Wolf: Dan is a down-to-earth, laid back, all-around nice guy. Until you harm, threaten to harm, or screw over his wife, children, or sister-in-law. Once that happens, run. Just...run.
- Parental Neglect: Dan's mother was (literally) insane, and his father was a traveling salesman who was rarely home.
- Tranquil Fury: If Dan's hollering and yelling, he's just blowing off steam. But when he gets quiet, run.
- All Girls Want Bad Boys: The basis for her relationship with Mark.
- Bratty Teenage Daughter: In the early seasons.
- Character Development: She eventually grew out of her bratty martyr tendencies to become a genuinely helpful person. One of the most telling signs was her moving into a trailer with Mark, a purposely hard road-not so she could complain, but for the sake of starting a life outside her parents' home. Later, she decided to go back to college and continue the education she'd missed out on after marrying Mark.
- The Chick
- The Dutiful Daughter: When Darlene seemed to slip into a depression during her tomboy-to-emo transition, it fell on Becky to pick up the slack. For a while, she ended up doing the majority of the chores without getting any recognition for it, and it only got worse when she saw Roseanne give Darlene money for clothes to try and snap her out of it.
- The Glorious War of Sisterly Rivalry: With Darlene.
- Happily Married: To Mark, despite all their issues. The finale reveals that she was actually married to David; Roseanne switched her and Darlene's spouses in her book because she thought those couples were a better match.
- Hormone-Addled Teenager
- Hypocrite: Sometimes. She accused Darlene of being selfish or stuck-up, but she had her own moments of this as well.
- It's All About Me: Her bratty tendencies put her in this territory.
- To emphasize, her response to her family hitting financial times yet again isn't to be sympathetic or supportive, but to get angry that there wasn't enough money for her to go to college or for her boyfriend to keep his job.
- "The Reason You Suck" Speech: Gives one to Darlene accusing her of milking her depression. She was harsher than she needed to be, but it did convince Darlene to get off the couch and do something.
- She also gives one to Dan when his bike shop business fails, claiming that it's Dan's lack of business skill that bankrupted the family, costing her both college and Mark (who was leaving Lanford to take a better job).
- Tomboy and Girly Girl: Girly Girl to Darlene's Tomboy.
Portrayed by Sarah Gilbert
- Big Sister Bully: To DJ, especially in early seasons.
- Book Dumb: In her early years. She became progressively more invested in her studies as the years went on.
- Break the Haughty: Went through some of this in seasons 7 and 8, especially 7.
- Character Development: In the first seasons, Darlene was a sports-obsessed tomboy who always had her hair tied back into a tight braid to give a boyish appearance. But the moment she started going through puberty she let her hair down, started avoiding sports all together, and abandoned all of her friends to become a Deadpan Snarker.
- Daddy's Girl: Darlene was closer to Dan than Becky was.
- Deadpan Snarker: After puberty, Darlene goes from a tomboy to this.
- Emo Teen: Seen as this by her family during the bulk of season 4.
- Girliness Upgrade: In the first three seasons, Darlene was a tomboy. Then she becomes a depressed Goth chick, wearing black and outright declaring her hatred of all things girly (to the point where Roseanne and Dan deliberately tease her by pretending to set up a stereotypical sweet sixteen party for her). After falling in love with David, she becomes slightly more feminine, though she never loses her love of flannels and jeans.
- The Glorious War of Sisterly Rivalry: With Becky.
- Happily Married: To David. In reality, she was married to Mark, while Becky married David; Roseanne switched the couples in her book because she thought that David was better suited to Darlene, and Mark to Becky.
- Heel Realization: Darlene went through this over the course of a few episodes after her break-up with David. She realized she felt closer to David than anyone and how much she hurt him by dumping him, as well as how badly she treated him. It didn't help that her new boyfriend dumped her for treating him the way she treated David.
- Jerkass/Jerk with a Heart of Gold: To a lesser extent when compared to her mother.
- Masculine Girl, Feminine Boy: The masculine girl to David's feminine boy.
- The Smart Girl: She is eventually revealed to be both poetic, smart, and a talented artist. Interestingly, her sister Becky got better grades in the early seasons, and while she never lost that intelligence, she did end up having to put her education on hold when she eloped with Mark.
- The Snark Knight
- Soapbox Sadie: In later years.
- Took a Level in Jerkass: Much like her mother, she slowly becomes more cruel and mean-spirited in later seasons. She mellows out later in season 8, though.
- Tomboy and Girly Girl: Tomboy to Becky's Girly Girl.
David Jacob "DJ" Connor
Portrayed by Sal Barone in the Pilot, then Michael Fishman for the rest of the series
Portrayed by Laurie Metcalf
- Abusive Parents: Jackie's father was physically abusive to his daughters.
- Break the Cutie
- The Chew Toy
- Freudian Excuse: Her father's aforementioned abuse is heavily implied to be responsible for her promiscuity and inability to have a successful relationship. It goes from being implied to outright stated after her ordeal with Fisher and her inability to let Fred get close.
- The Glorious War of Sisterly Rivalry: With Roseanne.
- The Lancer
- Large Ham: In later seasons.
- Really Gets Around
- Small Name, Big Ego: A common thread among her many jobs was that she always tried to talk them up to make them sound a lot more important than they were. She tried to make it sound like she was the star of a high school play when all she did was raise the curtain. When she was injured in the line of duty as a police officer, she always tried to talk it up as though she took a bullet saving a baby carriage, when in reality she pulled her back after she tackled some fat naked guy and they both fell down the stairs.
- Why Do You Keep Changing Jobs?: She rotated through factory worker, police officer, truck driver, theater actor, diner owner, before finally settling into stay-at-home mom. (Though she did still help out at the diner a lot)
Beverly "Bev" Harris
Portrayed by Estelle Parsons
- The Alcoholic: Played for drama in one episode.
- Specifically though, after she is sent to Alcoholics Anonymous, she uses this as a chance to make everyone else feel bad about not being more sensitive to her "illness" and judge them for supposedly being alcoholics themselves.
- Butt Monkey: Easily the most abused character on the show, though given her treatment of her daughters at times it's almost justified.
- Compassionate Critic : She sees herself this way, but everyone hates the things she says, even when she's trying to be nice. To Jackie: "I think it's wonderful that you have ideas, because if you don't keep having ideas, how do you know when you come up with a good one?"
- Domestic Abuse: Not stated, but it's implied Al was just as cruel to her as he was to Jackie and Roseanne. Not to mention the constant cheating.
- Extreme Doormat: To her husband, which could explain the way she treats her daughters.
- Good Girls Avoid Abortion: Is a pathological believer in this.
- Manipulative Bitch: At her worst.
- My Beloved Smother: At her best.
- Pet the Dog: Had a lot of these moments to keep her from being entirely unlikeable.
- Shotgun Wedding: It's revealed in season 6 that she and Al only got married because she was pregnant with Roseanne.
- Suddenly Sexuality: Outed herself in the final season. Though it turned out to just be a part of Roseanne's book, because she was disappointed in all the crap Bev had to take and wanted her to assert herself more.
Portrayed by Shelly Winters
Portrayed by Glenn Quinn
- All Girls Want Bad Boys: The basis for his and Becky's relationship.
- Big Brother Bully: To David
- Dumbass Has a Point: He noticed that, between seeing him buy a heavy winter coat and not breaking a work contract he was hired to do, Dan didn't really want to move back to California and wanted to stay and try to mend his marriage.
- Freudian Excuse: Comes from one hell of a broken home
- The Friend Nobody Likes: He had shades of this. David once pointed out that the only people who liked having him around were himself and Becky, which doesn't count for much since David is his brother and Becky is his wife.
- The Glorious War of Brotherly Rivalry: With David
- Happily Married: He and Becky had their issues and their marriage was on the rocks more than once, but for the most part they were this trope. [[Spoiler: The finale reveals that he was actually married to Darlene, but they also fit this trope]].
- Hidden Depths: Quite a bit in later seasons
- Jerkass / Jerk with a Heart of Gold: Depending on the episode or situation. Mostly the latter in the later seasons, especially during Darlene and David's wedding episode where he not only shows compassion towards the brother he bullied his entire life, but also his own pain over their crappy home life.
- Mr. Fanservice: Mark is extremely handsome, which is part of the reason Becky fell for him. In one episode, even Darlene admits that he's "gorgeous" (although she then declares that she must "gut herself like a fish" for saying so).
- Parental Abandonment: His parents threw him out of the house when he was 16.
- Pet the Dog: Gets a few of these moments with David, especially in the later seasons.
- Sensitive Guy and Manly Man: The manly man to David's sensitive guy.
- Took a Level in Dumbass: In the later seasons, a stark contrast to his early appearances.
Portrayed by Johnny Galecki
- Abusive Parents: His mother, good lord.
- Break the Cutie: Almost as bad as Jackie.
- Butt Monkey: For a time he was pushed around quite a bit by the others, especially Mark and DJ.
- Freudian Excuse: Darlene, the first person to consistently care for him, still had a tendency to treat him badly, and then he basically lost her when she left for art school. Adding that to the emotional abuse he suffered from his mom and the disrespect he often received from nearly everyone else, it's easier to understand why David started acting more snotty.
- The Glorious War of Brotherly Rivalry: With Mark. Also DJ, to a point.
- Happily Married: To Darlene (yes, really). [[Spoiler: It turns out that in real life, as opposed to Roseanne's book, he was married to Becky]].
- Henpecked Husband: He came across as a little spineless around women in later years.
- Masculine Girl, Feminine Boy: The feminine boy to Darlene's masculine girl.
- Sensitive Guy and Manly Man: The sensitive guy to Mark, Dan and DJ's manly man.
- Took a Level in Jerkass: Wasn't quite as sensitive and sweet in later seasons.
Portrayed by Martin Mull
- Bad Boss: Averted. Roseanne certainly treated him like one, but anyone else would've fired her after the first day.
- Deadpan Snarker: He kind of had to be to deal with Roseanne. Though really, it was give and take between them.
- Happily Married: To Scott
- Jerkass: At his worst
- Straight Gay: Lampshades the hell out of this during "December Bride":
Leon: Oh yeah! Well you just think about it, young lady. Hmm? I hate to shop! Huh, I am absolutely insensitive. I detest Barbara Streisand. And for God's sake I'm a Republican!
Roseanne: But do you like having sex with men?
Leon: Well it's...
- Vitriolic Best Buds: Eventually becomes this with Roseanne
Portrayed by Michael O'Keefe
- But We Used a Condom
- Dogged Nice Guy: Had this relationship with Jackie at first. When he finally got her (mostly because he impregnated her) they both realized it was a mistake.
- Only Sane Man: Never seems too effected by the insanity of Jackie's family, aside from occasionally being weirded out.
- The Stoic: Stood out by being perpetually laid back and calm, often making him the perfect foil for the ever-more-neurotic Jackie.
- Taking the Kids: A rare example where the couple's not even married; Fred sues Jackie for partial custody of their son Andy before the kid's even born yet. This is mostly because Jackie refused to let Fred have anything at all to do with Andy's life and Fred wanting involvement.
