To this day, it is difficult to verify whether the legend of Bloody Mary is true or false. As for whether Bloody Mary can summon terrifying evil spirits, there are many opinions on the Internet. Most people think this is nonsense, and there are no cases of people dying from playing Bloody Mary online.

There are more than 50 versions of the horrific legend of Bloody Mary circulating on the Internet. Some say she is a witch, while others say she is a disabled bride. But the stories are all very similar, that is, a woman named Mary brutally killed hundreds of girls and bathed in their blood to stay young forever. To this day, it is difficult to find the original version of the story, and no one knows whether Bloody Mary is real, but folk tales and legends are often adapted from real events. The most reliable theory is that Bloody Mary is Queen Mary I of England.

Mary I was an extremely devout Catholic. After taking the throne, she restored Roman Catholicism (old religion) in England, replacing the English Protestantism advocated by her father Henry VIII. To this end, she ordered about 300 opponents to be burned to death. So Mary I was called "Bloody Mary". Later, Bloody Mary became a synonym for witch in English.
