Necessary Evil: Temporary Ethics Fault
Kaiju is a strange creature. Believed by most to be a villain, it appears suddenly in cities and generally causes catastrophe. It stands fifty feet tall, and has a part-reptile part-insect character to it. It seems to be intelligent and to function intelligently, and appears to have specific objectives. It sometimes attacks civilians, sometimes kidnaps them, and sometimes ignores them or even attempts to defend them.
Whatever intelligence is within Kaiju, it is clear that it has some way to conceal itself. It has made a number of attacks over the years, but always disappears without a trace. It seems to simply vanish, and then no trace of it can be found until the next time it strikes.
