But when he finds a little plant, it’s a sign that life may be ready to resume. He then finds himself embarked by Eve, a robot sent by the humans to check for the presence of life on Earth. On the Axiom, the place where the humans now live, they meet M-O. M-O is a small robot specialized in cleanliness who will follow Wall-E obsessively, leaving traces of dust behind him.
