~ Thrax to the police while kidnapping Leah Estrogen.
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.
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.

(Captain Hook's pirates slither across the roof, pulling out their weapons. One of the pirates' feet lands on a girder, snapping it. Inside her room, Jane moans and writhes. A sinister metal hook unlocks the window and its shadow looms over her like a ghost. The shadow - Hook himself - opens up the window; Jane wakes up and gasps! Her eyes scan the streets, trying to find out where the sound came from. Jane closes the windows, thinking it's just her imagination, until she hears a creak.) (slowly and evilly) Hello, Wendy. (Jane gasps again, but before she can cry out, one of the pirates pulls a cloth over her mouth, gagging her!) (Smee, stuffing her in a sack: My apologies, miss.) (Hook twirls his mustache, but hears an air raid siren and rushes to the window.) Curses! Bring her down! (The rest of the pirates bring the ship down and lower the plank.) Hurry, Smee! (Jane struggles and kicks inside the sack.) (Smee: Oh come on, now, don't fuss.) (Jane squeals inside the sack as Hook's crew toss her onto the ship.) Cast off, ya mangy dogs!

(Leah gasps and the police watch the scene with frightened eyes.) (Leah: What are you waiting for? Shoot him!) (Thrax holds his claw to her throat like a switchblade.) If you follow me, she dies.

(Peter Parker and Mary Jane Watson are about to kiss when Peter's spider sense tingles. A car crashes through the cafe window, causing the lovers to tumble to the floor.

Suddenly, Doc Ock stomps over to the broken window and towers over Peter and Mary Jane like a rhino.) Peter Parker. And the girlfriend. (Peter: What do you want?) (With that, Doc Ock shoots out a tentacle, grabs Peter around the throat, and pulls him closely.) I want you to find your friend Spider-Man. Tell him to meet me at the West Side Tower at three o'clock. (Peter: But I don't know where he is.) (Doc Ock pulls off his glasses.) Find him. (The mechanical tentacles rise above Mary Jane, brandishing sharp claws.) Or I'll peel the flesh off her bones. (To emphasize his point, Doc Ock snaps a claw at Peter.) (Peter, firmly: If you lay one finger on her...) You'll do what? (Doc Ock tosses Peter against the wall, causing rubble to fall on top of him. He puts his sunglasses back on. Mary Jane spins around.

(Pazu: Don't hurt her!) (One of the guards hears Pazu.) (Guard: It came from over there!) (Soldier: Colonel, what's happening?) (Muska and one of his men hold Sheeta in their grasp.)
