I really hope that A) they collect this is paperback shortly down the road, and B) the series doesn't entirely focus on guys like Joker and Mad Hatter. There are some pretty wild villains who never appeared elsewhere, only appeared in background roles on Batman: The Brave and the Bold, or, in Egghead and King Tut's case, have only appeared once or twice in other comics.
Anyone who knows me knows what villain I want to appear.
Clearly, you mean either Tony the Tulip or Petey the Posy. Personally, I'd love a Vincent Price or Joan Collins figure, along with the sure to be on the radar Julie Newmar figure. If the line takes off, which I wonder if it can, could we hope for even more obscure characters? Thugs and goons, anyone?
