The great thing about this line is the possibilities for fans of other themes.
Joker, can be easily turned into a clown for a kids party for the town line.
Two Face and Killer Croc (and any other weird looking Villains) can be redone as StarWars aliens for a SAILBARGE, or Mos Eisley Cantina.
And of course with this, you could finally make a Lego comic book convention!! *sick*
