Little is known about Elsa's origin. She was presumably born and raised in the same South American city as the Mardon brothers, where she met and ultimately married Claudio, who soon became head of his family's criminal empire.
Elsa Mardon was created by Brian Buccellato and Francis Manapul. She made her first appearance in The Flash #10.
