Transmutation

From The 4400 Wiki, a fan encyclopedia that anyone can edit.

Transmutation is a promicin-induced ability that allows its user to break down and rebuild the molecular structure of an object, be it an inanimate object or something as complex as a plant, from the ground up, converting it to something else. The ability can be activated via. concentration or subconsciously.

Promicin Positive Meghan Doyle has this ability.
