Prudence(Prue) is the eldest sister in the original Power of Three and is gifted with the powers of telekinesis and astral projection. Prue's initial power was telekinesis through the mind. Later the power went to her hands as she got stronger. Her power of astral projection came in season 2. Prue is the most bad tempered amongst the three sisters, and the one with an attitude. It's hard to blame her for acting the way she did because she was the one who gave everything up to raise her two younger sisters ever since the unfortunate passing of their grandmother, Penny Halliwell. Her temper is much better controlled in season 3. Prue was killed by Shax (a wind hit-demon sent by the ultimate baddies, The Source) in season 3.
