David Kibner

Biography
Doctor David Kibner was a psychiatrist and self-help guru living in San Francisco, California during the 1970s. He earned himself celebrity status within his community and wrote several books. In 1978, an alien spore came to the planet Earth and began subverting the city's population by creating genetic doppelgängers of its inhabitants, which grew from large plant-like pods. Once this duplicate was fully formed, its host predecessor would die, their remains dissolving into dust.

It is unclear exactly when David Kibner was assimilated and duplicated, but it appears as if he may have been one of the first people in the city to fall prey to the "body snatchers". While most of these so-called "pod people" lacked an ability to express emotion, David's duplicate pantomimed human emotion in order to pass himself off as human.

Several of Kibner's patients came to him complaining that their loved ones were not who they were supposed to be. Kibner relied upon his reputation to allay their fears, telling them that this mass behavioral change was just an example of people shirking all sense of responsibility and commitment.
