...but, after the Crisis On Infinite Earths, Eclipso was working his way up to bigger and better things!
Those things included appearances in the Outsiders, Phantom Stranger and Starman..
A series of museum robberies put Batman and the Outsiders on the trail of the People of the Dark, and their high priestess, leading the Outsiders and Batman to the island of Diablo, where the Prime Minister of the land recounted the origin of Eclipso, how high priest Morphir scratched solar scientist Bruce Gordon with a black diamond during an eclipse....and Gordon was on the island at the time continuing his research along with his fiancee, Mona Bennet. The high priestess and her cult captured Batman and the Outsiders, who met Bruce Gordon, whom the priestess was using in a ceremony during the eclipse to reform...Eclipso (who must have reformed slightly during the Crisis, but had been bodiless since his last appearance facing off against John Stewart during his early run as Green Lantern. The Outsiders figured to wait until the eclipse passed to face Eclipso (since he was most powerful at this time), except...Eclipso made sure the eclipse wouldn't end!
This ended the immediate menace, but began a more tortured life for Dr. Bruce Gordon again...
Phantom Stranger faces Lycaon and his cult, with a little help from James Gordon against a demon, then confronts Eclipso, who, working with the Lords of Chaos and claiming to have just found magic, is subtly working to destroy the world, hiding his plans from all the usual heroes....with the Phantom Stranger looking for new allies, finding a disheartened Bruce Gordon.
While there, they discover the mystic connection to the supposed natural problems the Earth is having, with the doctor taking action to help Phantom Stranger and Gordon stop this particular problem, while Lycaon and his cult grow in power, as does Eclipso.
With one end of Earth ended, Eclipso focuses his mind on the next two.
Tensions between the U.S. and U.S.S.R. get worse, with Valentina Volstok (Negative Woman of the new Doom Patrol) working for the U.S. government trying to find the cause, with Jimmy Olsen finding the Russian mobster has ties much further up than he thought, being pursued by a demon Russian mobster, with Phantom Stranger showing up to rescue him (instead of his usual pal, Superman). Gordon, Olsen and the Phantom Stranger head to the White House, where it is found that the demon can shift bodies, and takes over the U.S. President, to begin World War III, with only the combined effort of the Phantom Stranger, Jimmy Olsen, Bruce Gordon and Ronald Reagan stop this world threat. Meanwhile, Lycaon works out a TV deal, and Eclipso hoping his last mystic end to Earth will be the one to end all life on Earth.
While in space, their ship runs into intergalactic bounty hunter Lobo, and, while Starman is occupied with him, the moon crosses the sun, turning Bruce into...Eclipso!
Lobo and Starman fight on the moon, while Eclipso retrieves his black diamond and costume (which he had subconsciously gotten Bruce Gordon to hide on the solar jet). Eclipso asserts that it was his satellite which had generated the energy beam which turned Will Payton into Starman, and that Eclipso had been using his heroic creation as an energy storehouse. Lobo and Starman's battle eventually brought them to where Eclipso had landed the solar plane, and Lobo was ready to take in Eclipso for his bounty.
But, Starman then learns of Eclipso's duplicity, nearly getting brain damage, as the villain takes the solar plane on the run to head back to Earth and Kitty at S.T.A.R. Labs....leaving Starman behind, realizing he will need help to defeat Eclipso.
Invasion!), exposing Eclipso to the concentrated sunlight Starman can generate...bring back Dr. Bruce Gordon. With the menace averted, Gordon is able to get answers for Starman's power surge, that it was natural, and he just has to get use to his new more powerful self.
