A classic villain pose. To show that he has defeated the hero, the villain lifts him over his head. As a pose, this has lots of benefits: It's visually compelling, it shows off the villain's strength, and it's a shocking way for the villain to brag about beating the hero, showcasing the hero's vulnerability. Think of it as shadow-Pieta Plagiarism-- instead of a loved one gently cradling a fallen hero, an enemy is holding his conquest up for the world to see. The followup action is usually to drop or throw him back to earth, perhaps with some force. Ouch.
