It is the evil that lurks in the darkness...and in the hearts of men. Its name is Eclipso, and its power is terrifying! When scientist and solar energy specialist Bruce Gordon travels to the jungle to view a solar eclipse, he is attacked by Mophir, a tribal magician, and wounded by a mysterious black diamond. Now, whenever Gordon is exposed to an eclipse of any kind, his evil half emerges as Eclipso - super-strong, nigh-invulnerable and able to shoot blasts of dark energy! This bumper, value-packed collection of the early Eclipso tales is written by comics legend Bob Haney ("Doom Patrol") and illustrated by a host of classic artists!
