Firestorm has the ability to rearrange molecular or particle structures of any substance into most anything else, creating different atomic structures of equal mass. He can transmute the basic composition of an object (e.g., transmuting lead into gold) and can also change its shape or form at will. Much like Green Lantern's limitations, Firestorm can only create items whose workings are understood by the "driver" of the Firestorm Matrix, through he can make more complex sentient constructs out of the Matrix's energies. Unlike Green Lantern's creations, Firestorm's alterations are permanent unless he reverses them.
