I would really like Damian's current costume, if not for all of the green. Really, it's hard to take someone seriously when they're dressed in christmas colors. I mean really, green boots with red laces? Is he supposed to be an elf?
The cape is kinda reminiscent of Ra's al Ghul's, even though if you take the original Dick Grayson Robin cape and pop the collar, that's pretty much what it would look like. So it's kind of a nod to both, I guess. The sword is another nod to D's grampa, but of course, he wouldn't use that as a killing weapon...right?
