When Green Lantern Kyle Rayner resurrected the Guardians of the Universe as children, he brought 50% of them back as females. Lianna somehow accelerated her own growth, becoming an adult of Amazonian stature, but not emotionally. Lianna has all the powers of an adult Guardian, plus superhuman strength, speed, and stamina, as well as electro-magnetic abilities she picked up during an encounter with Lady Styx. The source of her altered appearance and abilities has been revealed to come from the heartstone, a fraction of the gem that began the universe. Mother Zed was a Zamaron and member of a holy order. She became Lianna's major parental figure and kept her out of Lady Styx's clutches. After the death of Mother Zed, Lianna decides to officially join the Omega Men.
