I agree about breaking the page up into the separate continuities in question; right now, there's what looks like a random note about Batman putting his body count at 114 (around the same time the GCPD had somewhat overestimated him, incidentally, at 300), when it's actually near the beginning of the "New 52" reboot, establishing how many people this version of Joker has murdered thus far. - Cas Warner (talk) 07:33, May 20, 2016 (UTC)
