The Marcy's Sister is a character from Species II. She was woman who was engaged in a sexual encounter with Patrick Ross on the night of a fundraiser/party. 

History (film)Edit

When first seen, Marcy is accompanied by another woman she introduces to Patrick as her sister, claiming that they share everything together.

Shortly afterward, Patrick is seen having sex with Marcy while her sister watches them. After he finishes, the sister comes over and expresses that it's her turn to have sex with Patrick.

As they are having sex, tentacles begin to sprout from Patrick's chest and back, and the sister doesn't realize this until after she touches one of the tentacles on his back. She becomes terrified and screams, trying to get him off her, even calling Marcy for help. But Patrick continues to thrust into her uncontrollably as he reached orgasm and ejaculates into her as well.

It's not seen, but as a result of her sexual encounter with Patrick, she became impregnated with his hybrid offspring. Once she has given birth, she dies from the accelerated pregnancy and birth, survived by said offspring.

History (novelization)Edit

Unlike the film interpretation, the debutante's sister is a younger, dark-haired woman named Claudia. She encounters Patrick Ross in a hotel suite like in the film, and is introduced to him by the Debutante as her sister.

Shortly after the Debutante, whose name is revealed to be Lindsey, has finished having sex with Patrick and moves off the bed to go to the bathroom and allow her sister to have sex with Patrick, it's revealed that the Debutante's sister isn't really her sister but her best friend from college, and that they would every now and then go after unreachable men using their charms, often on a dare.

Sometime later, while still having sex with Patrick, Claudia discovers his tentacles and begins screaming for him to get off her, even trying to attack him and calling her friend for help, hearing Lindsey in the bathroom screaming (though she doesn't know why). But Patrick, as if under someone else's control, continues to have sex with her, even restraining her and asking why she was fighting him. Once he has reached his climax with her (her struggling actually helping him get closer to his goal), he releases her in order to relax, and she gets out of the bed.

No longer hearing Lindsey in the bathroom, she approaches the bathroom, but is then forced back onto the bed by Patrick (who, by then, has become a monster), restraining her and keeping her from screaming.

She later goes through the same accelerated pregnancy her best friend went through and dies minutes later.



According to the novelization of the film, she wasn't Marcy/Lindsey's sister, but her best friend from college. They had often dared each other to go after men during their time in college, succeeding in seducing most. In the novelization, she was waiting for Patrick with her best friend in the hotel suite on the bed, clad in only matching, silk lingerie. In front of Patrick, Lindsey reached over and ran her hand slowly up Claudia's thigh, sliding her fingers beneath the line of fabric at the hip joint and Claudia shuddered, suggesting that Lucy/Claudia may have had lesbian experiences with Marcy/Lindsey when they were with other men.

Patrick RossEdit

They meet up in the hotel suite with Marcy/Lindsey. There, she is introduced to him as her "sister" and they engage in sexual intercourse. Once they're done, she declares him a hero and allows her "sister" to have sex with him while she goes to the bathroom. As they continue, she begins to notice that he has sprouted tentacles on his body and begins screaming for Marcy to help her get him off to no avail. Once he has finished having sex with her, he holds her down on the bed and restrains her until she gives birth to his child.

Her sonEdit

She doesn't really have a relationship with her and Patrick's son. After being impregnated by Patrick, she immediately gives birth and dies shortly after.
