It's fun seeing Power Girl use her head to take out the Ultra Humanite (who is currently controlling Terra's body). Jimmy Palmiotti and Justin Gray set up a neat conflict for the issue; Power Girl is powerful enough that I think Terra probably couldn't beat her, but Terra's powers can cause insane amounts of collateral damage. Factor in that PG can't really unload on her foe because it is a possessed friend and you've got an interesting and pretty unique fight. PG acts quickly first dunking Terra then taking her into space to knock her out while removing any Earth-moving power use. Very clever.
I'm not sure how I feel about PG zapping Satanna's arm off, but I suppose the villain is a brilliant surgeon and geneticist, so PG probably knew she'd be fine. And it is worth it for the reaction shots of Satanna's animal men. The tigers looked shocked and the badger looks like he's going to be sick!
The story wraps up a little too neatly by having Terra's underground society have a convenient answer for all the big problems. They can put brains back in right bodies. They can heal most wounds and diseases. They can wipe memories. BUT, I'm actually ok with it because any other option would darken this comic (and the character) too much. What I love about PG is that she's a pretty upbeat person and I don't want to see that change.
Amanda Conner does another phenomenal job. Look at Satanna's animal followers killing time in their HQ, with the elephant and rhino man tussling. Look at the Ultra Humanite (with Terra's brain), how pitiful does it look? And that face-crunching beat down PG delivers at the end was tremendous. I'll miss this book after next issue.
