Platinum

A rare find in the DC catalog, Platinum made her entrance in 1995's Guy Gardner: Warrior #29, brought to life by the creative team of Beau Smith, Phil Jimenez, and Brad Gorby during comics' Modern Age. With only a handful of catalogued appearances spread across Guy Gardner: Warrior and Superman, she's a blink-and-you'll-miss-it presence who shares her pages with an intriguing crowd — Mercury, Lead, Veridium, Redmond Wilde, and Jimmy Olsen. For the dedicated DC completist, tracking her down is exactly the kind of deep-cut treasure hunt that makes collecting so rewarding.
