I've never even heard of this beetle character but he looks awesome. Maybe have a flying move like Hawk Girl.
He was a great character in the JLA in the 90's, got wrecked by Doomsday in the Death of Superman storyline. Not so sure about the new 52 one, it's too diffrent from the other character to have peaked my interest.
I remember in one of the interviews Boon did he mentioned that they were looking at certain DLC characters. He then said that they were going to go for fan favorites and then he said that he wanted both Lobo and Blue Bettle in the game even though he did not know who Lobo was. I don't remember which video it was but he was speaking to a large crowd of people, I think it was at Comic-Con
Paul McCartney might make DLC sometime.
