Matter Absorption and Abstaining

With Johnny's right hand, he can willingly absorb solid matter from the source, into any part of his body - or his entire body - and use it in various ways, gaining some form of advantage, enhancing the user's strength, speed, endurance and agility in many cases. With his left hand, he is able to abstain the material that he absorbed earlier, onto any object that isn't a biological life-form.
