The first Black Owl was Doug Danville millionaire playboy, who first appears as K the Unknown in Prize #1 and as Black Owl I in Prize Comics #2. Later in Prize Comics #34 we meet Walt Walters who was the father of the twins Rick and Dick Walters, who had been fighting crime for a couple of years under the names "Yank" and "Doodle". He would become the Second Prize Black Owl with the boys functioning as Dad's sidekicks.
It seems that there may be some new life being breathed back into The Black Owl, as well some of the other old public domain comic book heroes that appear in the PROJECT SUPERPOWERS SERIES. This has hopefully given new characters like Black Owl, Silver Streak and others in Dynamite's other series like THE DEATH-DEFYING 'DEVIL and BLACK TERROR as well in arcs that first launched in November 2008 .
