When the electric grid and cloud computing get knocked out on the same night, the Metropolis High Hamsters aren't quite sure how to deal...with a cafeteria that only accepts cash? And some of the girls are more affected than others: Batgirl without her smartphone barely makes it to school at all, but Green Lantern is mostly determined to keep her friends safe. Speaking of which, has anyone seen Bumblebee? With half the team out of commission, how will the girls find the source of the problem and fix it before Sweet Justice runs out of non-frozen desserts?! DC Super Hero Girls: Powerless continues to develop the relationships forged throughout the beloved DC Super Hero Girls series."(W) Amy Wolfram (A/CA) Agnes Garbowska
