Freedom Fighters. as I've been a fan of them since their appearance in JLA #107 and #108 it's great to see them animated.
and now that I've read what's been done to them recently, I'm even happier they chose to use the classic lineup with the classic costumes and heroes.
it worked well for the cartoon. they travel to Qward to stop an invasion of Earth. they don't mention of Qward is in another dimension, but it really doesn't matter for the story. what matters is how the action takes place!
and then we get this:
Captain Bat-America. it's just as awesome as it looks, and he even uses a shield of sorts.
