Abby is a vampire girl from the 2010 American remake of the 2008 Swedish movie Let the Right One In which is based on a 2004 novel of the same name. She is a completely different character from the one in the novel and the 2008 film.

As a vampire, she needs blood to survive and has her 'father' kill for her. She is easily enraged and, being a new vampire, has a hard time controlling her thirst for blood. When Abby arrives at Owen's home, she tells him he has to invite her in, when he asks why, she enters anyway, starting to tremble and bleed from head to toe. Shocked, he quickly tells her she can come in, and she stops bleeding.

Like most vampires, she has superhuman strength, reflexes and senses and a high healing factor. She can also transform into a flying creature and is presumed to be immortal.
