DETECTIVE COMICS #987
Then, the pulse-pounding "On the Outside" storyline hurtles toward its cataclysmic conclusion! Batman has tasked Katana, Black Lightning, the Signal and Orphan (a.k.a. Cassandra Cain) with stopping a rogue operator using alien technology that can crack into any mind on Earth! What does this case have to do with the Brainiac Files seen in JUSTICE LEAGUE: NO JUSTICE #1? And how does Amanda Waller factor in? Guess you're "outside" of Batman's circle of trust... for now.
