A week of prep and Batman's got this locked up.
this guy developes plans to take down superheros on the fly, let alone waiting around for a week. lol.
And if it's JLA/Batman, he might not even need that, he was blowing up Alex Nero's constructs when he was drawing off the ION energy. He's kung-fu'd up characters higher than most of those on the list with no prep, no devices, or anything.
