Mattie Harcourt

Stepping onto the scene in the very first issue of Peter David and Gary Frank's celebrated 1996 Supergirl relaunch, Mattie Harcourt is a supporting player woven into the fabric of one of DC's most distinctive Modern Age runs. With just 13 catalogued appearances spread across Supergirl and Supergirl Plus, she's a quietly recurring presence in a book that drew devoted readers throughout its late-'90s run. She keeps compelling company — sharing pages with the Danvers family and a cast of characters that made this corner of the DC Universe feel genuinely lived-in — and for collectors who treasure that era, spotting her name is a warm reminder of what made this series special.
