Demons are pretty cool. Asethetically, I mean. They're rad. That's why the Bat Demon Black Half Mask is cool. It looks like somebody took a load of Scarecrow's hallucination gas, fought Batman, and out this came. Makes perfect sense to me. Now, whether you want to look like a nightmare version of Batman or just one of the Devil's many minions, that's up to you, but you've got to make the first step by grabbing the Bat Demon Black Half Mask. Remember, like anything else, it all starts with you.
The Bat Demon Black Half Mask look like a nightmare version of Batman (I'm assuming somebody got hit with a bad load of Scarecrow gas) mixed with a demon from Hell. You can't lose with that combo.
