A new story arc begins in Justice League of America 18, and it looks to be a fun one.
Batman has left the team, and in his wake, a reporter comes to interview the other members of the group. It's not too hard to tell that the reporter is more than he seems. His questions are designed to elicit strong emotional responses from the League members, and are effective enough to send the Ray packing as well, at least for the short term.
I suppose enough time has gone by, thanks to my falling behind in my reviews, that I can safely reveal that everything happening in this issue is the work of Prometheus, out to destroy this incarnation of the League. Prometheus is a character that has not always been used well, but this story neatly evokes a lot of the same elements from his introductory story in JLA, when he infiltrated the League's Watchtower on the Moon, and took the team out one by one.
I also feel the desperate need to point out that, in a brief scene setting up another story arc, we see Dr Chaos being defeated. This exceptionally obscure character faced Superboy back in the early 80s, and was, essentially, an evil version of Dr Fate. Never thought we would ever see him again.
I always enjoy well crafted tales that tear a team asunder. They can play so effectively with the varying personalities of the members, and allow for some character development that works into the plot, when done right. And here, it is done right. Of all the characters to freak out and bolt, the Ray was the one I thought least likely, so it was all the more powerful to see him lose it.
