Four years later, The Shade was paroled for good behavior and began quietly stalking the Flash on his visits to Earth-One, using his cane to measure the vibratory frequency to Earth-One.  He then used his access to what he called "The Dark Dimension" to raid Earth-One from hiding, using shadow forms that were either constructs or denizens of the Dark Dimension.  The Flash of Earth-One recognized the shadowy shapes as the likely work of the Shade and traveled to Earth-Two to recruit Jay Garrick.  Together the two Flashes unraveled his schemes and sent the Shade to prison on Earth-One (The Flash #151)

During the 1970's, the Shade become a highly active member of the Injustice Society. In 1975, he was part of a large team organized by the Wizard what encountered a multiversal incursion from Earth-Prime when a comic book writer named Cary Bates acquired super-powers and malevolent intent when he inadvertentl inadvertently crossed over to Earth-2.  Backed up by his abilities, the Injustice Society scored some initial victories but were ultimately undone when he was returned to Earth-Prime and they were confronted by the combined might of the Justice League and Justice Society (JLA #123-124).  The following year he joined a group of villains from Earth-1, 2 and S under the direction of the barbarian conqueror King Kull from Earth-S.  He joined Dr. Light from Earth-2 in a series of crimes using satellites to affect the planet's illumination until they were thwarted by the Hawkman and Hawkgirl of Earth-1 and Bulletman and Bulletgirl of Earth-S (JLA #135-137).  At the end of the decade, he joined an Injustice Society venture with the Fiddler and the Icicle that was interrupted by the agents of Apokolips needing the unique combination of their abilities to resurrect Darkseid.  While the three villains executed their tasks as expected, the resurrected Lord of Apokolips nonetheless blamed them for subduing his son Orion and imprisoned them in the bowels of Apokolips for the effrontery. There were liberated by Batman and Mr. Miracle, who need them to reverse the conditions that led to Darkseid's resurrection.  They were presumably returned to prison on Earth-2 afterwards (JLA #183-185).

In the early 1980's, The Shade again crossed the dimensional barrier to Earth-1 when the actions of Roy G. Bivolo, the Rainbow Raider, shunted the color out of Central City into the dimension of Earth-1 causing a "pale-out" there while Keystone was drenched in uncontrollable colors that thwarted the Shade's ability to manipulate darkness.  He staged a series of crimes to attract the attention of the Earth-1 Flash and the two formed an uneasy alliance to discover the origins of their respective disruptions.  As the battle with the Rainbow Raider neared it's climax, the Shade cloaked the Flash in a shield of darkness and quietly slipped back into the Dark Dimension (The Flash #298-299).  The Shade was not seen during the Crisis on Infinite Earths and it is unknown whether he participated unseen or had retreated to the Dark Dimension til it was over.  His current activities are unknown.
