This Lum gassing scene has a corresponding anime version. In this set of images, I included a few good "peril" shots of Lum, and one decent pinup I found. The main crux of this scene is Rupa, the villain, kidnapping Lum by gassing her with a "mushroom".

The same mushroom gas technique is used later on a bride during her wedding.

The scene could have been better. The unconscious shots of Lum are very low resolution.
