Origin stories in comics can be pretty changeable. As different writers take on a character, small changes get made to their background. A lot of comic characters have been around for a long time too, so as times change, their story often alters to reflect the ideals and values of the current time.

Selina Kyle's Catwoman is no different. Since her debut in "Batman #1" Selina has changed from villain to anti-hero, from amnesiac flight attendant to street thief, and plenty of other things in between. Following her creation by Bill Finger and Bob Kane, Selina has been through some pretty big changes.

10 She Faked Her Amnesia

When Selina Kyle first appeared, she was known as The Cat, and was a former flight attendant with amnesia. After a blow to the head during a plane crash, Selina turned to a life of crime. A second blow to the head helped her to regain her memories. The first change to Selina's origins came just a year later when she revealed during The Brave and The Bold that she never actually had amnesia. In fact, she had faked the whole thing in order to leave her life of crime.

9 She Had An Abusive Husband

Selina's beginnings as a flight attendant were over-written quite early in her history and have not returned. One popular explanation for her criminal ways, however, is a background of abuse. In The Brave and The Bold "Vol 1, #197," Selina reveals that she turned to crime after escaping an abusive husband.

Her ex-husband held onto her jewelry, so she broke into his private vault to get it back. She found she enjoyed and had a talent for cat-burglary, and so, Catwoman was born.

8 She Worked As A Dominatrix

The next change came in 1986 when Frank Miller and David Mazzucchelli reimagined Batman's origins in Batman: Year One. In this version of her origins, Selina is a cat-loving dominatrix, who was inspired to don the costume by watching Batman, although she has chosen crime rather than preventing it. In the limited series Catwoman: Her Sister's Keeper, Mindy Newell and JJ Birch kept Catwoman's past in sex work.

7 She Didn't Work As A Dominatrix

Parts of Frank Miller's Catwoman origins have remained canonical, but many writers have rejected the idea that Catwoman was a sex worker and dominatrix. In order to bring together the two versions, many stories have chosen to explain the contradictory background as Selina pretending to be a sex worker in order to scam lonely men and rob them. In some versions, she has used this work to lie low and hide from her enemies. Her history may have changed, but many characters from both Year One and Her Sister's Keeper have stuck around to this day.

6 She Might Be A Member Of The Falcone Family

In Batman: Dark Victory, by Jeph Loeb and Tim Sale, it is implied that Selina believes herself to be the long-lost illegitimate daughter of Carmine Falcone. Falcone is a powerful mob boss and an enemy of Batman.

She spends some time looking into this but is unable to find definitive proof. This link is explored further in Catwoman: When In Rome,  by Jeph Loeb and Tim Sale, and while more circumstantial evidence is found, no hard proof of Selina's links to the mob family is given.

5 She's An Orphan

Later, it is revealed that Selina is an orphan after her mother committed suicide and her father drank himself to death. After the death of her parents, Selina spent some time on the streets before being sent to an orphanage and then Juvenile Hall. Later, she discovers the hall's administrator is corrupt and is embezzling funds. Selina steals some documents to send to the authorities to prove his corruption. At the same time, she also steals enough money to live on and goes back to the streets.

4 She Was The Daughter Of Rex Calabrese

In 2011, DC rebooted the entire line of comics, giving 52 key characters new beginnings in The New 52. For Selina Kyle, this meant becoming the daughter of mob boss Rex Calabrese. After Calabrese's arrest, Selina was placed into foster care, where she lost contact with the rest of the Calabrese family. She grew up in a group home, where she learned to steal in order to survive. After being caught trying to burgle someone's home, Selina was enrolled in a second-chance program for those raised in poverty.

3 She's Had Several Different Siblings

During her time in comics, Selina's family has changed several times, including whether or not she even has siblings. During Catwoman: Her Sister's Keeper, Mindy Newell and JJ Birch introduced her sister. Maggie has been a reasonably consistent part of Selina's origin since her introduction, but there have been times when she seems to have disappeared. During Selina's time in Juvenile Hall, there is no mention of Maggie and Selina doesn't appear to know her sister is even absent. During The New 52, Selina has a brother, Aiden Mason, with who she loses contact after she goes into foster care.

2 She Lost Her No-Kill Rule

Selina has always been presented as a morally ambiguous character, living by her own code. At times in her history, she has had a No-Kill rule, much like Batman himself.

However, at other times, it appears she has no issue killing when she needs to. In "Catwoman #52," the villain Black Mask goads Selina, threatening the most important people in her life. He believes she still adheres to a No-Kill rule, but Selina takes him by surprise by shooting him in the head. It seems Selina will kill when she feels it is justified or needed.

1 She's Both A Villian And An Anti-Hero

Whether or not Selina is a villain has always been a gray area. In her original incarnation as The Cat, she was definitely seen as a villain, but it didn't take her long to reform. Her reasons for turning to a life of crime are often attributed to necessity, such as escaping abuse or life on the streets. Her relationship with Batman is often a catalyst for her to reform. She has also allied herself with heroes and villains alike and has often teamed up with other morally gray characters, such as Harley Quinn and Poison Ivy in Gail Simone's Gotham City Sirens run.
