Gehenna

Gehenna is a young woman with a mysterious connection to the Firestorm matrix, introduced during the era of Jason Rusch's tenure as Firestorm. She possesses the ability to transmute organic matter, making her both an ally and a volatile presence in Firestorm's world.

Emerging from the darker corners of DC's Modern Age, Gehenna made her debut in Gail Simone and Dale Eaglesham's Villains United #4 in 2005 — a launch point that immediately signals she was born into morally complex, high-stakes storytelling. Over the following years she carved out a presence across Firestorm, Justice League of America, and Countdown, keeping company with heavyweights like Firestorm, Green Lantern, and even Bruce Wayne himself. With a collector-recognized key issue among her appearances and a publishing footprint stretching nearly two decades, Gehenna is one of those Modern Age figures who rewards the dedicated reader willing to dig into DC's rich ensemble tapestry — a character whose relatively intimate appearance count makes tracking her down feel genuinely satisfying.
