The following weapons are seen in the anime series Elfen Lied:
File:Vector1.jpg The primary "creatures" in the series are a murderous female race called Diclonius, and they can only be harmed by high caliber bullets such as .50 caliber bullets.
File:S.A.T.jpg MP5 Used by the Japanese S.A.T officers as standard issue submachine guns.
File:Bondo2.jpg .50 caliber Desert Eagle Used by Bando when he learns that only high caliber weapons can harm Lucy.
Barrett M82 Used by a S.A.T sniper to shoot Lucy in the head. She was unable to deflect the massive .50 caliber slug, thus the resulting impact caused brain damage and the creation of a split personality ~ which in turn played for an important plot device in the series.
