Just read Knightfall TPB. I was wondering after JPV removed all his Batman Armour and met his defeat at the wit of Bruce Wayne, where did his armour went to?
Did Bruce kept it up?
Would it be nice to have some villian stole that armour and use it against Bruce, as we didn't really see both Batmen in a brawl in the KF storyline?
Maybe Promethus can make good use of the armour against Batman.
I always assumed Bruce would have it locked up somewhere in the Batcave. But, according to wikipedia's entry on the Batsuit:
The gauntlets from this costume are now being used by Kate Spencer, the current Manhunter, who obtained them from a LAPD evidence room. They had been used by a small-time crook who unsuccessfully robbed the safe of a Gotham lawyer who keeps information on all his supervillain clients' loot.
So, I guess someone got that suit out of the Batcave and started selling off the pieces. I betcha someone could do a good story about an underworld auction for this Batsuit...
