What makes RHOBH such a great city in the franchise are the Housewives on the roster. While there were staples like Kyle Richards, Lisa Vanderpump, and Lisa Rinna, some Housewives didn't have the same kind of impact. However, from season 1 to season 12, these former Housewives were all unique in their own way.

Kathryn Edwards (Season 6)

Kathryn Edwards ed the women of Beverly Hills for one season in season 6. Her main highlights were her relationship with her husband and former NFL player, Donnie Edwards. She also argued with RHOBH friend Faye Resnick, who wasn't seen as the most likable member of the group, according to Edwards.

After the murder of model Nicole Brown and the involvement of OJ Simpson, Faye wrote a book about the ordeal and dropped Kathryn Edwards' name, even though the two didn't know each other. In the end, Edwards decided she enjoyed her privacy more than the fame and didn't re-sign for a second season. Kathryn was a strong Housewife but wasn't the most entertaining or likable.

Carlton Gebbia (Season 4)

Carlton Gebbia was a highly intelligent Housewife who ed the cast in season 4. Her time on the show was short-lived, but she caused some drama in the group, slowly becoming one of the most hated Housewives of Beverly Hills. Carlton was a Wiccan and styled her home in a gothic, raising eyebrows within the cast. This included Kyle Richards. According to Cheat Sheet, Kyle said in an interview that she tries not to season 4 because of Carlton.

Joyce Giraud de Ohoven (Season 4)

Along with Carlton, Joyce Giraud de Ohoven is another Housewife from season 4 who didn't last long. She was a married mother of two and former Miss Puerto Rico. And like some of the other ladies on this list, she also dabbled in acting. During her short time, Joyce got into a few altercations with Lisa Vanderpump and Brandi, but she wasn't dramatic or entertaining enough to keep her spot on the show.

Denise Richards (Seasons 9-10)

Denise Richards was one of the highest-paid Housewives when she ed in season 9. As a famed actress and notable celebrity, it was thrilling for Denise to the series and have an inside look at her private life.

After an exciting season 9, Denise had a harder season 10. After rumors that she cheated on her husband with former Housewife Brandi Glanville, Denise fell from grace as she defended her marriage. The drama was too much for her, and she slowly stopped appearing at cast events. After the season 10 reunion, Denise revealed she wouldn't return for season 11.

Teddi Mellencamp Arroyave (Seasons 7-10)

Teddi Mellencamp Arroyave was a great addition to The Real Housewives because of her famous family and connection to Beverly Hills. Although she was new to the group, she became close friends with Kyle Richards, and the two of them went against the group. Unfortunately, Teddi was less entertaining than the other Housewives. Although heavily involved in the Puppy Gate scandal, she didn't add much value to the series and left after season 10.

Adrienne Maloof (Seasons 1-3)

Adrienne Maloof was an absolute powerhouse. She had a strong presence on RHOBH because of her relationship with her husband, Paul Nassif. They were also neighbors with the Vanderpumps, which made for fun TV. Adrienne was a cast member for three seasons before stepping away, but she still showed up as a guest or friend over the years. Adrienne was more than a cast member because she was friends with these women outside of filming. Allegedly, Adrienne quit the series because of a vile altercation with Brandi revolving around Adrienne's children.

Taylor Armstrong (Seasons 1-3)

This Oklahoma native was heartbreaking during her relatively short tenure on RHOBH. Taylor was introduced in season 1, but it became evident by Kyle's white party that Taylor's marriage was in ruins. Regarding the other Housewives, Taylor got along with everyone nicely except for Kim Richards, Camille Grammer, and Brandi. Taylor was a huge part of the Dinner Party from Hell. Although she left RHOBH, she recently starred in season 2 of The Real Housewives Ultimate Girls Trip and is set to star on The Real Housewives of Orange County!

Brandi Glanville (Seasons 2-5)

Is Brandi Glanville one of the most hated Housewives of Beverly Hills? She's been part of the series since becoming a guest in season 2 and still pops up in storylines, even though she's no longer a main cast member. Brandi was the villain of the series because of her quick tongue and inability to keep a secret. Amidst the increasing drama, Bravo fired her after season five.

According to Cafe Mom, Andy Cohen said that the ladies of Beverly Hills "hated" Brandi, and Brandi felt the same way about them, so it wasn't a good mix. However, it's easy to hate-watch Brandi.

Kim Richards (Seasons 1-5)

Kim Richards is another OG Housewife that fans loved to watch. Even after all these years, she's not forgotten. As the sister of Kyle Richards, the two had a unique relationship filled with unconditional love and hatred for one another. Kyle was emotionally drained from helping her with her addiction issues. The sisters tried to mend their relationship, but other of the cast kept getting involved. By season 6, Kim entered the series as a friend without a diamond.

Eileen Davidson (Seasons 5-7)

What made Eileen special was her openness about her personal life. She showed viewers what it was like to be a soap opera star, but she was also incredibly raw about being married once before and having an affair with her current husband. She took control of the situation and laid it all on the table. Reality Blurb noted there were rumors made by Lisa Vanderpump that Davidson was fired, but Eileen came back swinging and claimed she was the one who left the show willingly.
