DC revealed the creative teams and some of the covers for the Futures End one-shots they plan to suspend the entire New 52 line in September to make room for. Given that Futures End is a possible alternate future that will never actually come to pass, these are basically inessential reading, along the lines of the #1,000,000 issues that tied in to the DC One Million series, or those weird-ass "Legends of the Dead Earth" annuals from 1996. It therefore seems like a really bad business plan...except, of course, for the fact that it gives them an excuse for a mess of new #1s and gimmick covers, along the lines of those somewhat animated, 3D-like covers from last September's Villains Month decimal-pointed issues.
Relatively few of those comics were any good, and I wasn't really wowed by the covers at all, but I do like the online gifs created to show off the covers. Here's one for this September's batch.
Now, I'm not sure what the exact story with that issue of TEC is, but I think it has something to do with the fact that The Riddler, like the Wicked Witch of the Oz, will disintegrate if he comes into contact with water, and so Batman is trying desperately to shield The Riddler from the rain with his large, umbrella-like cape, but, despite his best efforts, a raindrop hits The Riddler and he disappears. I think.
