704. The Sinister League 20: The Raven and the Bat
Sameth on April 16, 2014
Batman has some mental blocks. No powers, just a lot of training. He can still be mind controlled, but it's more difficult with Batman.
Also, I wasn't sure with Raven and the Phantom Zone, but I know some of her powers involve dimensional traveling and such and I figured since the Phantom Zone was another one, she might be able to sense it. Well, she can for this story, anyway. Plot contrivances and whatnot.
