Using this ability, Darren will be able to mimic water, air, earth and fire. He will only be able to do so deliberately, and will normally consciously choose which of the four elements he copies, though he could also mimic fire automatically if he doesn't choose another, since this will be the element he feels closest to and most connected with. He could transform his entire body, or just a limb or part of a limb such as a hand. However, the ability cannot be used to transform others into the elements, nor to control or create the elements.
