[Lycanthrokeith]

Hi all.

Looking for suggestions on movies, art, games, comics, anything really, with a transformation "If we don't beat them, we'll become them" theme.

The classic example of this trope would be "Night of the Living Dead." The idea is to have the tension of a carefully-waged conflict, where the human side is aware of what's happening or quickly learns within a short time of the start of the story. A single mistake causes someone to change sides in the conflict (either slowly or quickly) as they physically and mentally transform into whatever the adversary in question is.

Thanks in advance.
