Marvel: Life-Energy Transfer

Ruth Bat-Seraph (Sabra)
She is able to charge other individuals by transferring to them her own life energy, in the process enhancing their physical state of health and granting them low-level super powers which are, apparently, at random and otherwise unrelated to Sabra's own mutant powers. The recipient retains their new powers until Sabra herself decides to withdraw them by retrieving her life energy. Her standard power levels drop when she gives away her life energy, but they return to normal once she takes her life energy back. lalalalalalalalalalalalalalalalalalalalalalalalalalalalalalalala
