This Bunker reminds me of me in a way. He acts like he doesn't take any of it too seriously. But a wall like that doesn't come out of thin air. He's got more going on than anyone gives him credit for. You watch-- he'll be in the Justice League before he's twenty.
The DC Universe heavily changed its continuity into the DCnU following the events of Flashpoint in 2011. This was part of an effort to make storylines more accessible to newer readers, beginning with the New 52. This new timeline combines elements from the DCU, Vertigo Universe and Wildstorm Universe while drastically changing the origins and histories of characters.
