Antagonist Idea - Invasion of the Body Snatchers

[Zadeon]

Okay, how about when a plant man is killed, they release spores that infects the nearest person. Then that person will eventually turn into a pod person automatically after a set time if they don't get medical attention. This way it makes them more of a threat when trying to deal with them. And there should be no indication if your infected (but a physical cloud should appear). That way if a group of people kill one they all have to go check if they are infected or not. The time it should take for somebody to turn should be short-ish. Basically, if you are infected and don't start heading for medical, then that's it for you. One more thing, your body would be taken over BY THE PERSON THAT YOU KILLED. With this, it would help reduce the effect of people forcing themselves to be assimilated so that they can be an a tag.
