EVE (Extraterrestrial Vegetation Evaluator) is an advanced probe droid. Called "Probe One" by the Captain of the Axiom, EVE is one of several robots who are sent to Earth on a scanning mission. An advanced model equipped with a laser gun and capable of flight and high speeds, she is determined to complete her task and initially fails to notice her would-be robot Romeo, WALL-E. The two robots subsequently bond, however, and the more she sees how much WALL-E cares for her, the more she falls for him, eventually making it her top priority to protect him.
EVE has all necessary parts of a probe droid. She has an ergonomic suitable shape, scanner, flight at high speeds to cross ground quickly and morphable fingers for different purposes. However, it is odd that a simple probe would have a laser gun. This may have been put in only to make EVE look tough and dangerous.
- WALL-E designers said EVE was modeled after Apple's new brand of computers and i-pods.
