11 Justice League Fates Worse Than Death
8. Knowing Your Friend Has Planned Your Death - Tower Of Babel
Oh, Bruce...
One of the main characteristics of Batman is that the World's Greatest Detective is forever prepared for any and all threats that may rear their head. And in the Tower of Babel story, it's unfortunately the Justice League who are on the receiving end of Bruce's ever-prepared nature.
In Mark Waid, Howard Porter and Steve Scott's four-part 2000 tale, it's revealed that Batman has secretly put together records on the strengths and weaknesses of his fellow Leaguers - complete with intricate details on how to defeat each member of the JL.
This only comes to light to the Justice League, mind, when Ra's al Ghul steals this information and sets about taking out the League one by one. Superman is exposed to Red Kryptonite, Wonder Woman is trapped in a never-ending virtual fight, Wally West is brutalised by light speed-induced seizures, Martian Manhunter is engulfed in flames, Plastic Man is frozen, Kyle Rayner is rendered blind, Aquaman is made aquaphobic, and even Batman himself is targeted as the League of Assassins steal the corpses of his deceased parents.
One could argue that Bruce was right to have such contingency plans in place should any of the League go rogue, but for his fellow heroes his secret records come across as totally underhand and lacking in any trust.
