Power Girl #11

Power Girl is in a battle against a mind controlled Terra. Power Girl thins the air so Terra is knocked unconscious. She carries her over the shoulder to the villain who knows where the real Terra's brain is. After she rescues another person with a swapped brain, the evil Terra wakes up and starts fighting Power Girl again. Power Girl then rams her head into a pillar to knock her out again. Terra is turned back to normal by being put into a restoration tank.
