I'm a sucker for prop replicas. And this Batarang from the Arkham City video Batman video game is right up my alley.
Of course, it's a full-scale replica weighing 20 pounds. The Batarang is detachable which means, should crooks actually break into your house, you could grab this bad boy and throw it at them. I wouldn't advise it, but you could. And how could would it be if it actually worked?
Anyway, the lights at the base actually light up, which would make this thing the focus point in any room.
Want one? Well, only 750 were made so good luck!
