Greta Hayes

Greta Hayes, known as Secret, is a mysterious young woman with ghostly, smoke-like abilities who becomes connected to the Young Justice team. Her tragic backstory involves her existence as a spirit-like entity, giving her an eerie, ethereal presence among DC's young heroes.

A quietly haunting presence in the late-'90s DC Universe, Greta Hayes made her debut in Young Justice #4 (1999), brought to life by the celebrated team of Peter David and Todd Nauck at a moment when DC was reinventing its young-hero landscape for a new generation. Her appearances across Young Justice, Impulse, and JLA/JSA Secret Files & Origins put her in remarkable company — sharing pages with the likes of Wonder Girl, Robin, Tim Drake, and Bart Allen, the bright, energetic core of DC's millennial youth movement. With a catalog presence stretching all the way to 2023, Greta has quietly endured far beyond her debut era, a testament to the staying power of the stories that introduced her.
