When Blackfire’s latest doomsday machine backfires and blows up her entireinvasion fleet before the Titans can leap into action, our heroes are left with a freeafternoon. Good thing there’s a giant sack of (Justice League) fan mail to answer!Everything’s fine until they open a “special delivery” from one of the League’sgreatest foes: an Amazo robot that’ll crush the Titans with its own powers! Anduntil the postal inspector shows up, don’t open other people’s mail, kids.
