Adventures of Superman Annual (1987-) #5
This is out of order with the rest of the issues in the Reign of the Supermen story line.
Of all the New Blood I think Sparx had the most potential. Granted, she was in Superboy and the Reavers which while not really a hit comic, lasted longer then any comic the other Bloodlines heroes got, save Hitman. So sad though it is, she had more success then most. But of the ones who might deserve a second chance in the current DC Universe, Sparx would definitely be near the top.
