Not just one.

As we close out the astronomical reign of Gemini we can’t help but think about all of the twins that have graced daytime over the decades. Usually one good and one evil, it’s a plot device that will continue to be used on soaps until the end of time, although there are certainly some shows who used it more than others.

Because there are so many we could never include them all, so here are 10 of our favorites from “All My Children,” “Another World,” “The Bold and the Beautiful, “Days of our Lives,” “General Hospital,” “One Life to Live,” and “The Young and the Restless.” Is your favorite set of twins missing? Let us know who they are in the comments below.

Stuart Chandler and Adam Chandler, All My Children.
It’s hard not to think of the iconic good twin/bad twin portrayal of the Chandler twins by David Canary for decades on “AMC” almost immediately when considering daytime duos. You couldn’t help but love the simple artist Stuart and his pure-hearted sweetness that was such a stark contrast to his conniving businessman brother. Over the years Stuart became the ideal sounding board for anyone in Pine Valley looking for a moral compass, especially calculating Adam whose soft spot for his brother was unmatched. It hurt fans deeply when it was revealed Adam was the one who killed Stuart in a haze, and his later return from the dead did little to ease that hurt.

Marley Love and Vicky Hudson, Another World.
Sometimes twins turn up at just the right time on soaps, like when someone is in dire medical straits that only matching DNA can fix. Such was the case when privileged Marley Love (Ellen Wheeler, Anne Heche, Jensen Buchanan) was diagnosed with leukemia just after her long-lost twin Vicky came to town in a play to swindle Marley out of her inheritance. They butted heads from the start but the two grew close after the life-saving procedure, eventually embracing their sisterhood. Still, there was always an undercurrent of tension between the two.

Cassie Newman and Mariah Copeland, The Young and the Restless.
Twins can sometimes seem to come out of thin air on daytime, just like Mariah Copeland (Camryn Grimes) did when she arrived in Genoa City in 2013, hired by Victor Newman (Eric Braeden) to be a literal ghost in order to drive Sharon (Sharon Case) crazy while she was off her bipolar meds. Fans were fine with the suddenly sibling though, since they were so devastated when young Cassie died after a car accident in 2005 – but not before cryptically telling Nick (Joshua Morrow) from her deathbed that he and Sharon would have another daughter. Years later, prophecy fulfilled.

Victor Lord Jr. and Todd Manning, One Life to Live.
“One Life to Live” was so loaded with twins it became hard to make the plot point very original – until these two came along. After Todd (Roger Howarth) was thought to be dead, a man named Walker Laurence (Trevor St. John) came to Llanview claiming to be Todd, though they looked nothing alike. Over time it eventually became clear he really was Todd – until Howarth’s Todd came back to town. Each claiming to be the true Todd, a test proved the men had matching DNA but it wasn’t until 2011 when the full truth came out they were not the same person, but twins. To say these two never bonded is an understatement.

Dr. Marlena Evans and Samantha Evans, Days of our Lives.
With a real-life twin sister in her back pocket, it was only a matter of time before Deidre Hall’s psychiatrist character Marlena had an evil twin sister (Andrea Hall-Lovell) arrive in Salem, and Hall admits it was one of her favorite storylines to play over the past 40 years. An aspiring actress with a drug problem, Samantha was consumed with jealousy and used her acting skills to take over her sister’s life. They eventually tried to patch things up, but Samantha was mistaken for Marlena and killed by the Salem Strangler.

Natalie Marlowe and Janet Green, All My Children.
This pairing is a personal favorite because the time when Janet “from another planet” (Kate Collins, Robin Mattson) was impersonating Natalie (Collins) while keeping her trapped in the well in an effort to get Trevor (James Kiberd) was the front-burner storyline when I first started watching “AMC” with my mom as a teen. Poor Trevor was eventually found in Janet’s freezer years after Natalie slipped into a coma and died in 1993, though she returned to Pine Valley every once in a while as an angel from heaven for years after.

Ryan Chamberlain and Kevin Collins, General Hospital, Port Charles.
When it comes to evil twins, it doesn’t get much more psychotic than serial killer Ryan Chamberlain (Jon Lindstrom). Ryan followed Felicia Jones (Kristina Wagner) to Port Charles after she witnessed him commit murder in Texas, then she developed amnesia. The two dated until Felicia’s memories returned right as he proposed, but Mac (John York) saved her from the mad man. After that, Ryan beat Audrey Hardy (Rachel Ames) and kidnapped Maxie (Robyn Richards) before his good twin Kevin came to town, forcing him to spend a long time making sure everyone knew he was a psychiatrist and not a psycho like his brother.

Cassie Brady and Rex Brady, Days of our Lives.
Perhaps the strangest set of twins to come to daytime, Cassie (Alexis Thorpe) and her twin Rex (Eric Winters) were discovered half-naked in pods after a 2002 meteor shower, which led people to initially believe they were aliens. The twins had matching tattoos of a phoenix, which initially linked them to Stefano (Joe Mascolo), but that wasn’t the case at all. The twins were really the children of Kate (Lauren Koslow) and Roman (Wayne Northrop, Josh Taylor), made up of their stolen sperm and eggs. This confusion in parentage led to some near familial hookups before the truth was revealed at Caroline’s (Peggy McKay) funeral when everyone thought she had been killed by a serial killer.

Cindy Parker Chandler and Karen Parker, All My Children.
Just like the sweet Stuart Chandler who she dated and eventually married, Cindy Parker (Ellen Wheeler) was the good twin to the not-so-nice kidnapper Karen, who snatched baby JR and demanded $1 million in ransom for the child’s safe return before she left Pine Valley. As for Cindy, it was eventually revealed that she had contracted AIDS from her drug-addict ex, but that didn’t stop Stuart from marrying the love of his life before she died of the disease.

Phoebe Forrester and Steffy Forrester, The Bold and the Beautiful.
After twins Phoebe (Mackenzie Mauzy) and Steffy (Jacqueline MacInnes Wood) made it through their mother Taylor’s (Hunter Tylo) harrowing pregnancy, they had just a few happy years before Steffy fell off a boat and was presumed eaten by a shark when they were just toddlers. Thankfully, she was only kidnapped by a deranged stalker of Ridge’s and safely returned. They both went to school overseas to grow up, and when they returned to LA they tried to live life among the Forresters. Phoebe was devastated when the boy she was dating, Rick (Kyle Lowder), fell in love with her mother, and while fighting with him in his car she caused him to crash which led to her own death.
