In this scene, "Sargon, Mistress of War" is possessed and attacks her ally, Lord Cumulus. Another character, Lord Chaos, intervenes, KOing her with a blow to the back of her head!

Not the best scene, but the woman on the cover was too sexy to ignore. I found a minor KO towards the end.

Kakio is bitten by a female vampire. She wakes up in bondage.

This is an OLD scene. The very first Buck Roger's story, and it has a good gas scene! This is probably the oldest scene in the database.

Toshio gets a face full of sleeping gas. Threw in a scene where Toshio hand gags Ai (girl with short hair. Hitomi's sister).

Toshio is gassed again, this time by a female detective in glasses. She holds a cloth over her own mouth to protect herself from the sleeping gas. Later in the volume, a bunch of party goers are gassed by Hitomi. The trick is on her though, as everyone managed to sneak gas masks on.

Hitomi is blasted unconscious by a gush of water.

A female security guard is knocked out by a female thief (named Rui Kisugi).

Mrs. Incredible is knocked out briefly by sleeping gas. It's kind of a silly scene actually. Not enough unconscious shots. I kept it anyway!

"Sargon, the Mistress of War", is knocked unconscious by a blast!

The thief known as MOUSE gasses a facility, and a girl gets caught up in it.

All three girls get gassed by a woman weilding a spray can. They wake up bound and gagged. Nice scene! Side note: This manga has a lot of bondage in it, but most of it is not appropriate for this site.

A woman sprays Kakio with a face full of sleeping gas, with a canister she has hidden up her sleeve. Wake up scene from volume 8 included.

A young karate girl gets in a fight, but the bad guys discover her weakness (which is snakes). They basically cause her to faint by throwing snakes at her.

Tyrygosa is in peril again. This time, she is snagged by a tentacled monster and her energy is drained.

A blue dragon transforms into a beautiful female and lands unconscious into a warrior's arms (named Jorad).

Nice Gag.

Supergirl gets into a tough fight with Maelstrom (a very strong female villain). She is rendered unconscious, but Superman comes and rescues her. The defeat really hurts Supergirl's ego though.
