About Samara Morgan

Sadako Yamamura is a fictional character and the main antagonist of Koji Suzuki's Ring novel series and its eponymous film series. Her backstory varies between continuities, but all depict her as the vengeful ghost of a young psychic who was murdered and thrown into a well. As a ghost, she is dressed in a simple white dress usually with long black hair hiding her face, and uses nensha, her most distinctive power, to create a cursed videotape; whoever watches the tape will be haunted by Sadako and die exactly one week later unless the tape is copied and shown to another person, who must then repeat the same process. The titular "ring" from the novels and films refers to a ring-like visual that appears on the cursed videotape, which depicts the top of the well as seen by Sadako from its bottom. Korean and American films reimagine the character as Park Eun-seo (Korean: 박은서) and Samara Morgan, respectively, with similar backgrounds and features.
