The Doppel Gang
A criminal gang that assumes the forms, right down to DNA and fingerprints, of other individuals.
On April 26, 1967, disguised as famous celebrities, including Lyndon Johnson, Elizabeth Montgomery and Jimi Hendrix, the Doppel Gang committed a series of bank heists. In the course of one robbery, they fought the Silver Agent.
They have the ability to mimic people, whether through supernatural means or technological means.
