Jason Bard

First appearance: Detective Comics #392 (October 1969)








Jason would return in further Batgirl stories, and when her feature in Detective Comics ended in 1972 (after Barbara Gordon was elected to the U.S. Congress), Jason Bard was one of the rotating characters who took over the back-up feature in Detective Comics starting with issue #425 (July 1972).





And from Who's Who: The Definitive Directory of the DC Universe Vol. XI (January 1986),

And if anybody wants to read the rest of that story,







The Elongated Man would have the back-up feature in the following issue, but Jason would be back in that slot for the odd-numbered issues through #435.
(The Archie Goodwin and Walt Simonson update of Manhunter would begin with Detective Comics #437.)
