So i wanna make a list on the various criminal gangs or leaders Batman/batfamily has faced.I don't consider Ra's al Ghul,Kobra,Joker or Bane to be crime bosses.
So Let's begin
Black Mask and the false face society
Black Glove/Dr Hurt/Club of villains
Court of Owls/Talon
Great White Shark
Killer Croc(classic,though modern version is also a mostly hired gun)
proceed after this.
