*Spoiler Alert!*
Anyone else ever notice how Batman's secret files on the Justice League are always getting them into trouble? Here, the Riddler and the Legion of Doom stole the files and used them against the league. In Mark Waid's JLA arc "Rock of Ages" Ra's Al Ghul was behind it. Geoff Johns did it twice: first in Infinite Crisis when Batman's surveillance system Brother Eye became sentient under Maxwell Lord, unleashing hordes of OMACs on the world, and more recently in the New 52's "Trinity War" when "The Outsider" stole the contingency plans from the Batcave.
The perils of being paranoid...
Maybe Batman is actually the Justice League's worst enemy?!?
