Jack Douglas Palmer

A brief but intriguing presence in DC's Modern Age, Jack Douglas Palmer made his entrance in 2010's Brightest Day: The Atom Special #1, brought to life by the acclaimed Jeff Lemire and Mahmud Asrar. His handful of appearances place him in genuinely distinguished company — sharing pages with Ray Palmer, Barbara Gordon, and Oracle across titles like Adventure Comics and Giant-Size Atom. With only four catalog appearances, he's a rare find for dedicated DC completists, the kind of quietly compelling figure who lingers at the edges of a fascinating corner of the DC Universe.
