Mama Bear: To her children, her sister, her daughter's boyfriends who she eventually all but adopts. Basically, if Roseanne considers you family or a loved one, she will unleash full fury on anyone who's wronged you.
Progressively Prettier: Roseanne was never straight-up ugly, but she was very overweight and as a hard-working blue collar Midwestern woman, personal appearance was fairly low on her list of priorities. However, as the seasons wore on, Roseanne the actress began to wear much more flattering hair and makeup, lost a bunch of weight, and combined with her real life surgeries, her looks definitely improved.
All Bikers Are Hell's 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.
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. She'd have been more sympathetic if she hadn't had such an attitude about it.
Jerkass: The rest of the family puts up with much, much more of Becky's crap than anyone would realistically tolerate, and some of her worst moments are resolved by one of the other Connors apologizing to or appeasing her.
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.
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.
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.
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)
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.
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
Blind Without 'Em: "If she wears her glasses, she'll be in Lanford by 9. If she forgot 'em, she'll be in Lansing by midnight."
Open Minded Parent: Played with. She was more of a free spirit, but Bev viewed this as a bad thing because she believed she had no stability when she was a kid, coupled with the fact that she never knew who her real dad was. Mary reasoned that the reason Bev became so straight-laced and conservative was because she was specifically rebelling against Mary's liberal tendencies. Since this was during season nine, which later revealed that the entire show was a book Roseanne was writing, this is most likely Roseanne's interpretation of Bev and Mary's relationship and the reason behind it.
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.
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.
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.
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.
