He was also asked about DCU not using thier 2nd characters:

If you could poach one character from DC, which one would it be?
Heh, well ... I don't know, exactly. The obvious answer is Batman.

But I get the feeling you like some of the secondary characters.
I'm not going to name any particular one, but I will say there are times when -- and I'm going back years and years -- when I was very jealous of some of the Vertigo titles. There was some neat stuff going on. And some obscure stuff that could be interesting,

I'm going to word this delicately…
Oh boy.
As for me I would love to see The Falcon in Cap 2,but where's Black Panther? $#@@## IT!!
