Also read the All Star Comics. That was easier on the eye, at least art-wise. Power Girl didn’t have the chest window, but still surprisingly busty. This Vandal was purely driven by reacquiring lost immortality. But that snazzy green number definitely made him more appealing. While he lays down some decent plans, he is usually thwarted by teamwork.
In that Green Lantern, Alan Scott realizes Vandal’s plan because of something Doiby Dickles said. Whose alleged accent seemed all over the place. Someone so refined as Alan would likely call him “Derby”…
In All Star Comics, as the heroes find each other, they start putting pieces together, and with the cosmic converter assist, Vandal is thus thwarted. Not on topic, but does the Star Spangled Kid grow up to be Starman (or is it Star Man?)?
