Cylon (Battlestar Galactica)
Reptilian hosting

'In the 1978 series, the Cylon is also the name of the reptilian race who created the robot Cylons.'----

[Interesting TV series with bad guys called Cylons who are human looking and if killed can be reborn in a new body, which is a similar concept to Reptilian hosting and human possession (series 1-2).]
