Captures and Kidnapping

In any story, there comes a time when the villain captures or kidnaps someone (usually the hero, heroine, or someone he/she cares about). He or she does it for these reasons: Not all villains can do that, but when the antagonist abducts or captures someone, it can quite raise the stakes. Noteworthy examples are alien abductions, Captain Hook's kidnapping of the Darling children, and Lo Pan capturing Miao Yin and Gracie Law to marry/wed and sacrifice.

 * In the case of the heroine, to marry against her will.
