A double, an identical replica of a person. The idea behind this is that everyone has a Doppleganger, an identical copy of themselves somewhere in the world. If the person is good, then the Doppleganger will be evil and vice versa. It is even said that if the two should meet, then they will both perish.

Although there is no evidence that Dopplegangers exist, some people have actually reported claims of witnessing what they believe to be their Doppleganger. In all likelihood however, Dopplegangers are an aspect of myth only
