Piper's Powers

Piper Halliwell
Piper's powers are particle manipulation, so any future powers she may of received would have been in some way related to particles. Because both Piper's powers are quite powerful (the most powerful of the three) she only received two, but may have received more in the future, though it is unlikely. Instead of receiving new powers, Piper's advanced.

Temporal Stasis (Freezing Time)
This is Piper's first power, the power to slow down particles until they completely stop.  Piper's freezing power is very advanced, she can freeze anything within the room, and outside the room as well (as long as its visible). When she freezes something, it stays frozen until she unfreezes it. Piper's powers also work on some upper-level demons, but they can usually fight the freeze.
Other Names: Molecular Inhabition
Characters: Piper Halliwell, Patricia Halliwell, Melinda Warren

Molecular Combustion (Blowing Things Up)
This is her second power, the power to speed up particles until they explode. This power is the strongest out of the Power of Three, and is very advanced. Piper can blow up any object, and most demons, although upper-level demons are more difficult. Not all demons explode. This power can also be channelled through the eyes, though Piper can only channel it through her hands.
