[quote=UDC canon]Harlequin – The Joker inspired criminal has yet to debut, but Marcie Cooper might just be one of many to envy The Joker’s madness.[/quote]
[quote=UDC canon]In late October, the “Circus of Strange” rolls into Gotham City at the Haly Fairgrounds—The Joker “re-emerges” with accomplices Killer Croc and The Ventriloquist setting the stage to facilitate murder and mayhem. This becomes Robin’s most difficult and most personal fight yet. The Joker and Killer Croc are later captured and sent off to Arkham Asylum’s criminal wing after many injuries and casualties.[/quote]

Curious how you are going to tie these in your Joker's IC. I'd love to see more in origin, but as it stands it looks pretty good to me.
