Adventures of the Super Sons #12
It's been a long road, but Superboy and Robin have finally made their way back home! Unfortunately, an armada of about a gazillion juvenile super-delinquents is back too, and these pint-sized hell-raisers are out to conquer Earth! It's the final battle between the son of Batman, the son of Superman, a big fan of Lex Luthor and whatever a "Doomsdame" is in this epic finale to the Super Sons saga!
