There is a myth featuring The Ghost Who Walks, a powerful and indestructible guardian of the innocent and fighter of all types of injustice. Because he seems to have existed for generations, many believe him to be immortal. In reality, the Phantom is descended from 20 previous generations of crime-fighters who all adopt the same persona. When a new Phantom takes the task from his dying father, he swears the Oath of the Skull: "I swear to devote my life to the destruction of piracy, greed, cruelty, and injustice, in all their forms, and my sons and their sons shall follow me"
