Imposter Zombie is a zombie in Plants vs. Zombies Adventures. It is not actually one zombie; rather, two Imps hiding under a trench coat. When their trench coat is destroyed, a squeaky voice can be heard and the Imps jump out and start eating the plants on their own. While inside the trench coat, this 'zombie' deals more damage per bite, due to both Imps biting the plant at the same time.
