Naomi McDuffie

In an alternate universe in the DC Multiverse, the degradation of Earth's ozone layer exposes the surface of the Earth to a previously-unknown type of radioactive energy, causing 29 people from around the planet to develop godlike powers. Some of these people attempt world domination with their new powers, while others oppose this, leading to a cataclysmic war between these metahumans. One month later, fourteen of the metahumans have died, and seven others have left the planet, leaving only eight remaining. Naomi is the first child born to two of these metahumans. The most evil of the original 29 metahumans, a criminal named Zumbado, who was about to be executed when he got his powers, tries to kill the infant Naomi. Consequently, her parents send her to Earth-0 for her safety and are killed in battle doing so. The infant ends up in a small Oregon town, where a Rannian ex-soldier and resident of the town, going by the name Greg McDuffie, witnesses her arrival, and adopts her.

Naomi lives an ordinary life in her hometown raised by Greg and his human wife, who knows about her husband's secrets, until Superman crashes through the center of town in a battle with Mongul. This prompts a couple of citizens to talk about the previous time the town had an encounter with otherworldly beings. Having learned that the date of the incident was also the day she was adopted, Naomi questions whether she has a connection to superheroes and begins looking into her origins.

Greg then reveals his own origins to Naomi, before telling her about her arrival on Earth-0. He gives Naomi a device he found with her, which contains a message from her birth mother, and awakens her superpowers. Shortly afterward, Zumbado arrives and takes Naomi back to their original world, which has been devastated under his rule. Naomi fights Zumbado to avenge her birth parents, and only narrowly manages to escape back to Earth-0.

Following these events, Naomi flies to Metropolis, and meets Superman and Batman. She later joins the recently reformed Young Justice.

Following the events of Dark Nights: Death Metal, Naomi joins the Justice League.
