Diana Walter is a fictional character and the main antagonist in the 2016 film Lights Out, portrayed by Alicia Vela-Bailey. She is a vengeful ghost-like entity that attacks people in the dark, and can teleport.

Diana is a mysterious figure that attacks people only in the dark. It is revealed she was once a teenager committed to a mental hospital, suffering from a serious skin condition that prevented her from being exposed to any light. She befriends teenaged Sophie, who is hospitalized for depression. They take a picture together outside where she is covered in shadow by an umbrella. Doctors began performing experiments on Diana, but inadvertently killed her by exposing her to intense surgical-suite spotlights, instantly reducing her body to ashes.

Diana then turns into a demonic, malevolent creature that can act only in the darkness. The creature latches onto Sophie, and kills anyone who tries to help or be with her. She interferes with Sophie's intentions of trying to recover from depression, and frightens Sophie's young daughter Rebecca by taking her drawing of her family and inserting herself into it as a stick figure while rubbing out her father. Rebecca’s father is killed by her, though his family assume he abandoned them and Rebecca moves out as soon as she is old enough. Some years later, Diana appears at Sophie's second husband Paul's work place and kills him. She then haunts Sophie and Paul’s child, Martin, to the point that he is unable to get sleep anymore. When Martin is staying at Rebecca's, Diana goes there and haunts them, scratching onto the floor the same name and stick figure she added to Rebecca's childhood drawing.

Diana continues to influence Sophie, who suggests a stay-in movie night with Martin, including Diana as "the three of us", in an attempt to proactively introduce her son to her demon friend. When Sophie tries to take her anti-depressant medications, Diana knocks them aside. Diana tries to pull Martin under the bed, but Rebecca stops her. She locks Rebecca and Martin in the basement, and attacks Rebecca's boyfriend Bret, who is able to flee by activating his car headlights. She ignores Sophie's pleas to not hurt her kids, and continues to attack in the dark, killing two police officers. She reveals to Rebecca her killing of her father years before. However, as Diana is about to kill Rebecca, Sophie arrives and states that Diana only exists because Sophie has allowed her to exist. Sophie then shoots herself in the head, and Diana disappears.
