Biblical: Bardiel is known as both the Angel of hail, and the Angel of lightning.
Evangelion: His name is appropriate because in the show, when Evangelion Unit 03 is being transported to Japan from the United States, it passes through a lightning storm. Shortly after, when NERV tries to activate the Eva, it goes berserk, and they realize the entry plug (cockpit) cannot eject becuase the path is clogged with a white goop--the Angel. It takes down two Evas before Unit 01, and Shinji refuses to fight because he knows that a person is inside. Gendou activates the dummy system, which sends Unit 01 into auto pilot, at which point it proceeds to viciously tear Unit 03 and Bardiel to shreds. The fight scene ends with Unit 03's arm sticking out of the nearby river, and a trail of blood flowing away.
