Alan Scott was just a normal railroad engineer until he discovered a lantern containing the Starheart, a powerful mystic artifact concealed by the Guardians. He then used his immense power to become the crime fighter, the Green Lantern. His power does not come from a Green Lantern Corps ring. He is a founding member of the Justice Society of America, and is the father of Jade and Obsidian.
