EVE (Extraterrestrial Vegetation Evaluator) is the deuteragonist in WALL•E. She is an advanced probe droid. Numbered “01” by AUTO from the Axiom, EVE is one of several robots who are sent to Earth on a scanning mission.
An advanced model equipped with a quasar ion cannon 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.
