Though SCP-811 is not openly hostile or evil by nature, she is not above attacking humans if they make her feel threatened, or she's very hungry. The most prominent trait of SCP-811 is her need to feed and predatory nature. The SCP is also very opportunistic in her hunting tactics, which causes the Foundation to raise its guard when entering her containment chamber. As shown in the one interview seen on the official article, SCP-811 sometimes shows a compliant and even obedient side.
