I think the woman who gets injected is dead. But it looked voluntary.

A girl is choked unconscious. She's rescued and manages to recover.

Not sure what happens, but the evil twin gets knocked out somehow.

A girl is knocked out with a punch to the belly.

The good twin faints and is carried.

From a Chie Shinohara one-shot. The main character is knocked out and thrown into a house, which is subsequently set on fire. She faints from the smoke, but is saved.

From a Spanish adult comic. A woman sees what's been done to her dog and faints.

Eva Kant drowns but gets saved by Diabolik.

I believe this is from Fiction House. It's actually a male on male chloro, but I'm going to classify it as f/m because the female is the one in charge.

Doujinshi based on the Vocaloid synthesizer software. Basically, this girl has been drugged and is...you know. Source:

Supposedly this French show has a lot of kidnappings of the main female protagonist. If anyone can find some of the knockout scenes, please post them!

There is a very brief chloro. The girl initially thinks a certain thief (that she is in love with) gets killed, but he sneaked up behind her and chloroforms her. She is taken to his lair, where they make love or whatever.

Bondage on the cover. Spirit gets knocked out and tied up on the inside.

I think the cover is awesome. It's drawn very nicely and the girl has a very good sleepy expression on her face. Description: A pretty parachutist apparently was knocked unconscious when falling on a tree branch. Then came a lion, but who can blame him? Then came the Phantom...

This image is actually a composite of the front and back covers.
