Night of the Living Shadows Superman : Season 1 Episode 23

Lex Luthor develops a suit that enables a person to become a living shadow. He gives it to a low-level thug from Suicide Slum named McFarlane to rob a bank (who gets dubbed Shadow Thief), then uses the suit himself to rob a jewelry store. Lex then recruits a gang to use the suits in a plan to rob the mint where their robberies baffle Superman and Inspector Henderson.
