Lucy (ルーシー Rūshi) is a fictional character in the Elfen Lied manga and anime series. She is a diclonius girl, a mutant human sub-species. She is assumed to be fifteen but never explicitly stated (eighteen in the anime), and the central protagonist of the series. Lucy has vectors with a limited range of about two meters (6.56168 ft). However, she can be swift and lethal within that range, and will use any nearby objects as high-velocity projectiles to kill at greater distances. She is also capable of stopping or deflecting most standard ammunition when she concentrates on the task. More: en.wikipedia.org.
