Harley Quinn: The Animated Series - Legion of Bats! #2

Plot

While out shopping for new outfits at the New Gotham Mall, Harley and Ivy stumble across a possible recruit...but are they recruiting for good or for bad? And what loser(s) would dare to show up and ruin their shopping extravaganza? A very pissed-off Clock King and a butthurt Riddler. Meanwhile, Nightwing and Batgirl follow up on a lead that sends Harley reeling...as many villains' plans come to light. Everyone is out to tear our girls apart
