Helen Petrovna Blavatsky, also known by her real name Helen Hahn, is a character in the novel Final Destination: Destination Zero. She is an old psychic from Eastern Europe that Juliet Collins and Bill Sangster see in order to find out what was happening to the survivors of the Mornington Crescent explosion. Helen warns the two that Death is a force that does not like people who cheat him out of his game, and is a very sore loser. When Juliet asked her how to avoid Death, she simply tells her that it's impossible, because dying is a part of life, and not dying at the destined time only knocks the alignment of the universe out of order.
