Supergirl #30

Peter David, Leonard Kirk, and Robin Riggs set a genuinely unsettling mood for this March 1999 issue, with Supergirl crouched wide-eyed before a human skull while a massive, glowing-eyed shadow looms behind her — its chest bearing the familiar "S" shield in eerie pink. The tagline "A Shadow of Her Former Self!" promises a story wrestling with identity, and the moonlit iron-gate backdrop gives the whole scene a gothic atmosphere that feels a long way from sunny heroics. Kirk and Riggs's cover work is crisp and expressive, making issue #30 a compelling entry in Peter David's celebrated run on the title.
