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: * To use as bait or lure the hero/heroine into his or her trap. * To use as a slave. * To demand a ransom. * To demand someone's obedience. * In the case of the heroine, to marry against her will. * To feed or sacrifice to a god or a monster. * To force the police not to follow him or her. * In the case of predators or monsters, to devour someone.
