Does she really? She has Justice League, Batman Brave and the Bold, a animated arrow series, and going to appear on Arrow.Though DC looks to be smartly ignoring Arrow influence, apart from New 52 Green Arrow. Justice League she was in a love triangle, which in the character not a apart of the official ship, gets not the best treatment. I haven't watch all of Brave and the Bold, but still Bumble Bee has had promotion for kids and more recently. Also the name Vixen.....may sound too sexual (not my opinion, but it's a possibility).
