I still think tha Justice League would mop tha floor with tha "Waller's League".
Wonder Woman would beat Katana into a coma, lol! Remember tha sonning
streak Wonder Woman went on in tha old DCU before "Flashpoint":
Maxwell Lord
The Secret Six
That giant demon in that same Secret Six story arc
Mongul
Cheetah
I agree...Katana is the weak link in this book. They should have put Power Girl or Supergirl or Zealot or Voodoo on the team as a Wonder Woman adversary. Or they could have introduced the New 52 Universe version of Artemis or the New 52 version of Flint from the old Stormwatch book.
