Justice League of America #179

THE SIREN SONG OF THE SATIN SATAN Sponsored by Superman, Firestorm is inducted as the newest member of the Justice League. He is not required to reveal his secret identity—a fusion of the personalities of high school student Ronnie Raymond and physicist Martin Stein—nor is he made privy to the secret identities of the other members. After the JLA meeting, Ronnie Raymond becomes involved in the search for a missing classmate, Rosco Remington, who has disappeared from the Studio, a neighborhood disco. Becoming Firestorm again, he is mesmerized by the Satin Satan, a stunning villainess who is also responsible for Rosco's abduction, and he is forced to summon the JLA to his aid.
