Lab Rat

A rat raised to be used as a test sample by a research organization. It escaped the facility, and thanks to its high reproductive rate its numbers are exploding. Having been used in an experiment to see what would happen to monsters continually exposed to magic power, it gained great physical ability and intelligence. On top of being able to sniff out traps, it is also resistant to poison. It is an incredibly wicked monster which holds great resentment towards the humans who subjected it to such cruel experiments.
