All of the Shade's powers derive from his unique weapon, which is of unknown origin. Among the many FEATs which are possible with his cane are the following:

The Injustice Society of the World
At noon on a day in 1942, total darkness fell over Keystone City; not even electrical lights worked. The criminal mastermind known only as the Shade had created the darkness with his machine that prevented sunlight and other light from being reflected. Instead, all light except that produced by the special devices the Shade's gang possessed was absorbed by matter, leaving none for people to see by.
Under the cover of this darkness, the Shade and his gang captured the Keystone City's police force and looted the city's banks. However, the original Flash succeeded in restoring light to the city. Soon afterward, the Shade attempted to blanket in darkness the house in which a young woman was making her society debut and then rob the people inside. The Flash foiled this scheme and captured the Shade.
Many years later, the original Flash came out of retirement to battle the criminal alliance of the Shade, the Fiddler, and the Thinker. The original Flash was joined in fighting these three criminals by the second Flash, and together the two Flashes defeated all three of them.
Later, the Shade learned how to create vibrations with his cane that enabled him to enter a dimension of darkness he called the Dark Zone and to command the living creatures within it. The Shade then sent some of these creatures to Earth to rob for him. He captured the original Flash, but the second Flash defeated the Shade and freed his predecessor.
Since then the Shade has served as a member of the Injustice Society of the World, and temporarily allied himself with the second Flash against the Rainbow Raider. The Shade is still at large.
