It's all right there on the cover. Everything that happens in this issue is on the cover, rendered by Amanda Conner. Of course, inside the book, it goes into a little more detail. And, well, maybe Satana didn't make the cover. Terra eating sushi isn't there either. Nor is the outcome of the catastrophic battle under the world.
Palmiotti and Gray have their work cut out for them in trying to wrap this story up, while also balancing the new concepts and characters introduced herein while making them relevant and worthy of reinvestigating in the future. They do a great job, but the issue feels rushed in some areas, fluffed in others. Clearly, Palmiotti and Gray wanted to make a connection between Terra and Power Girl, which they do here, with the last few pages of the issue feeling like a preview of sorts for the Palmiotti- and Gray-penned "Power Girl" series, coming soon to a comic shop near you.
That said, the story is an almost formulaic comic book mini series fourth issue, except this issue features Geo-Force and Power Girl alongside the newly introduced Terra. This consideration allows Terra to be scrutinized a little more closely, as we learn that she truly is tabula rasa.
Conner's work here is as brilliant as always, hyper-kinetic, with vivacious characters teeming with energy and purpose. Her settings, backgrounds and "extra" characters also carry stories unto themselves and allow readers to play along a little, feeding the imagination.
I look forward to seeing this creative team in action again with the adventures of Power Girl, but to say this story was exceptionally memorable is a bit of a reach. In this instance, however, spotting Palmiotti and Gray's story with Conner's art, it doesn't have to be memorable; I'm certain to re-read it again, given that this creative team produces fun comics flat out.
