The original singer for million selling hard rock band the Lynx, Johnny Lynx nearly drowned while drunk, slipping into a coma. Returning under mysterious circumstances and cybernetically enhanced, Johnny waged a campaign of murder against his former band and their crew. Batman and Robin attempted to apprehend him, but in the course of the fight he fell off of a cliff, his final fate unclear.
He later appeared as one of the myriad of villains attacking Batman in dreams induced by Narcosis.
