Sibyll Trelawney
Sibyll Trelawney teaches Divination. She's terrible at it and does not have the "eye" as she likes to call it. Yet, dispite this she still seems to predict Harry's death every year and has produced a total of two real predictions. One, was when Pettigrew escaped from Sirius again, and ran back to Voldemort to help him regain power. Two, she predicted that a child born in July of parents that have three times out thwarted Voldemort will become his only enemy and in that only one of them could survive. Both predictions envolve Harry (the poor boy). Other than that the woman's a complete fraud and isn't worth the time of day...lol.
