The one who's copy we train against turned the rain to acid, as you have seen, its blood did likewise to the ground waters. Then there are the "Rifts" the kaiju make use of. Rends in the fabric of the world that allow them to travel between this one and where they originate. These poison intelligent life, causing confusion, aggression, imbedding one's ability to walk.

[ Just thinking about the actual extent of what these things to do is making him angry again. The anger's kept mostly internal this time at least, Godzilla bristling at the nerve of the kaiju for the extent. ]

One imagines this poison effects the other life in an area if it lingers too long. Though we have not failed so completely as to see for ourselves, a small victory we can take some pride in.
