The Fadeaway Man was a professor of art and history named Anton Lamont, who has a strong interest in occult items such as the Cloak of Cagliostro, which he uses for criminal purposes, making him an enemy of Hawkman and a member of the Secret Society of Super-Villains. The cloak granted him abilities of intangibility, invisibility and teleportation. In the Prime Earth continuity, he was succeeded by his grandchild Leo Lamont.
Fadeaway Man was created by Len Wein and Rich Buckler, first appearing in Detective Comics #479 (1978).
