Doppelgangers are enemies encountered in the video-game "Zombies Ate My Neighbors" and are a homage to the Pod People - they have mysteriously started to invade the world alongside many, many other monsters during the course of the game and may be connected in some way to the true antagonist of the game, Dr. Tongue, but like all the monsters their true purpose and origin is largely unknown.

What is known for certain is Doopelgangers can mimic the form of the hero of the game and emerge from plants, suggesting they may have a connection to another vegetation-themed horror in the game known as the Pod Plant.

Once they emerge Doopelgangers will pursue the hero of the game with the intent of killing and presumably taking their place in society, much as the Pod People did in the film "Invasion Of The Body Snatchers".
