Hrm...the comic issue is not out yet, so I'm not too sure what he calls himself anymore. They released pictures of his new outfit not too long ago, but not too much details about it.
Bascially what happened is that Dick Grayson's identity as Nightwing has been revealed to the world. He can't really use the Nightwing persona anymore, since there's no point to it anymore.
Looks like he might just be himself now--just Dick Grayson. But I'm only guessing. We'll only find out after the current major crises event in DC comics, and when the first new issue for Dick Grayson comes out.
Yeah, it's New 52. It's actually more related to a comic series called "Forever Evil" not the Nightwing comics, but he's a character in there.
Forever Evil is a seven issue series that includes a huge crossover of different comics and characters in the DC world. It's actually still going on, and the very last issue comes out this month. Forever Evil is really related to the Justice League. It helps if you have been reading the New 52 Justice League, but not really necessary I think.
It's a very interesting comic, and I like it a lot. It's more interesting if you know about other DC characters out there other than Batman, Superman, and Wonder Woman though. However, it think most people can enjoy it, but...it does have a lot of cameos that make it fun.
...although it is a dark comic haha. Nightwing is one of the biggest causalities of the event, but not the only one.
oh the cowl without the ears? Haha that was an interesting take on Tim's costume too. I'm pretty sure Tim's costume at that time was a direct reference to Red Robin in Kingdom Come. But I think DC needs to redesign his costume a few more times.
