Jade has a star-shaped birthmark on her palm, from which all her powers derive. All power ranks are based on the user's will power (equal to her Psyche rank, which is Remarkable for Jade). Her power ultimately comes from Green Lantern's power battery, but in her case, Jade's power is self-renewing and does not need to be periodically recharged. The power pulse, or any of its constructs, is ineffective against wood or anything closely resembling it. Jade has the following capabilities:
Acting * Singing
Inifinity Inc. * The Justice Society of America
Jennie-Lynn Hayden is the daughter of Alan Scott, the original Green Lantern, and Rose Forrest, the original Thorn. Forrest married Scott, and, unknown to him, had twin children Jennie-Lynn and Todd. Fearing her criminal Thorn personality would kill them, Forrest abandoned her children. Each twin was adopted by a different set of foster parents and did not meet until a few weeks before they attempted to join the justice Society of America. Jennie-Lynn had discovered that she could project mystical green energy, which she called her power pulse, from the green birthmark on her palm. Since she had green hair and skin, she used the power pulse to give herself a normal human appearance. Because of the similarity between her power pulse and Green Lantern's power-ring energy, she suspected that he was the father of Todd, who also had super-powers, and herself. The two siblings intended to become super-heroes under the names of Jade and Obsidian. Learning through the power pulse that four young heroes -- Fury, Northwind, Nuklon, and the Silver Scarab -- had just interrupted a Justice Society meeting to demand to be made members, Jennie-Lynn and Todd went to the meeting to ask that they be inducted, too. They claimed that Green Lantern was their father, but that he did not remember their relationship.
The Justice Society turned down all the applicants, who instead formed their own super-hero organization, Infinity, Inc. Jade revealed her Jennie-Lynn identity at Infinity, Inc.'s first press conference. Shortly thereafter, she and Obsidian met Rose Forrest and sometime later learned that she and Green Lantern were her real parents.
