Diana Walter is a fictional character in the Lights Out series. She is portrayed by Lotta Losten in the 2013 film and Alicia Vela-Bailey in the 2016 film. She serves as the antagonist of the films. She is a vengeful ghost-like entity that attacks people in the dark.

In the 2016 film Lights Out, Diana is a mysterious figure that attacks people only in the dark. It is revealed that she was a woman in a mental hospital that had Xeroderma pigmentosum, a serious skin condition that prevented her from being in any light. Doctors began performing experiments on Diana but finally killed her by overexposing her to light. But Diana did not die completely, converting herself into a demonic, malevolent creature that can exist only in the darkness. She latched herself onto her friend Sophie, killing anyone trying to help or be with her. She begins to attack Sophie's family. After several close encounters with Diana, Sophie's daughter Rebecca realizes Diana is in control of her mother. Rebecca convinces her boyfriend, Bret to help her defeat the vengeful entity. When Diana attacks Rebecca in the basement, Sophie kills herself to save her children, causing Diana to disappear as her entire existence relied on the life of Sophie.

Diana may appear in Lights Out 2.

David said that his goal was to keep Diana's appearance in the film as a silhouette. When asked about how challenging it was to keep Diana in the dark he said "Very challenging because I didn’t want to cheat. I had to storyboard all of it just to make sure that she was truly a silhouette. At first I was working with a storyboard artist. He would draw her with a rim light on her and I was like, “No, we can’t shoot it like that because that’s cheating.” So I had to do my own storyboards and really figure out how we could always keep her as a true silhouette. When she grabs Bret, I had to think about, “If he uses his flashlight like this to bang on the handle, if she grabs him when he’s up here, then the flashlight is pointed backwards creating a silhouette so that she can actually grab him.” It was really hard to figure out exactly how to get her on film." Diana was originally suppose to be more of a demonic presence but James Wan suggested that she have a human background so she could have a relationship to Sophie and add to the connection to the family.
