7) ALAN SCOTT
Waaaay back in 1940, Alan Scott discovered a strange, glowing lantern from which he carved a ring, becoming the original Green Lantern. His powers were eventually tied into the later Green Lantern Corps of space cops through The Starheart, a mystic artifact made by the Guardians Of The Universe. When his ring was destroyed (by editorial caveat) during Zero Hour, the mystic flame of the Starheart took up residence in Alan’s body, restoring his youth and giving him new life as the hero called Sentinel.
