I just finished watching this not too long ago and when it got to here I didn't even realize he was suppose to be Bruce...until I heard Kevin Conroy. XD I flipped out a bit saying, "Hot damn!" and "Hottest Batman ever!" I'm glad you did this screen shot dev since I want to be able to reference back to it.
well its basically his eyes and the way he gives the serious glare. Not the hair or anything. Or it could be the fact that the animation resembles the one in Death Note. Either way...thats my thought. Lol yah he does resemble Conrad alot here^^
