WALL-E (short for Waste Allocation Load Lifter: Earth-Class)[1] is the main protagonist of the 2008 Disney/Pixar animated film of the same name.

He is visited by a probe sent by the starship Axiom, a robot called EVE (short for Extraterrestrial Vegetation Evaluator), with whom he falls in love and pursues across the galaxy.

[3] Before they turned their attention to other projects, Stanton and John Lasseter thought about having WALL-E fall in love, as it was the necessary progression away from loneliness.

He found the latter idea "powerful" because it allowed the audience to project personalities onto the characters, as they do with babies and pets: "You're compelled ... you almost can't stop yourself from finishing the sentence 'Oh, I think it likes me!

[9] WALL-E's eyes were inspired by a pair of binoculars Stanton was given when watching the Oakland Athletics play against the Boston Red Sox.

[12] Sound designer, Ben Burtt saw a hand-cranked electrical generator while watching Island in the Sky, and bought an identical, unpacked device from 1950 on eBay to use for WALL-E moving around.

After all the humans leave Earth aboard giant spaceships, millions of WALL-E robots and a lesser amount of mobile incinerators are left behind to clean up the dirty planet.

He hides out from sandstorms and rain in his truck, spending his time sorting his collection, the pride of which is an old Betamax copy of the musical Hello, Dolly!.

Once the ship lands, it deposits EVE, a robot sent back to Earth to evaluate the soil to check for signs of ongoing photosynthesis, proof that life is sustainable again.

WALL-E is fascinated with this new robot and is excited to see someone else besides himself for the first time in hundreds of years, and soon falls in love with her, wishing to hold her hand like he'd seen done in his favorite movie.

WALL-E engages in a cat-and-mouse chase, pursuing the cart robot carrying EVE to the bridge, not realizing that M-O is following his trail to clean up the dirt his treads left behind.

WALL-E mistakes the diagnostics to be hurting her and breaks out to try and help her, accidentally blasting the power console with her blaster and freeing other malfunctioning robots.

After a chase through the Axiom's halls evading security, EVE tries to send WALL-E home in an escape pod, but he refuses to leave her.

Once inside, WALL-E offers to help EVE, but she tells him to stay put near the pool while she goes up the garbage chute to deliver the plant to Captain McCrea.

But Auto, still obeying a 700-year-old directive issued by Buy n Large CEO Shelby Forthright, is determined to stop them by tilting the ship.

After Auto is defeated and the Captain rights the Axiom, EVE rushes over to the holo-detector and attempts to pry it open to free WALL-E, but to no avail.

WALL-E wakes back up, but his memory is wiped clean and he reverts to his original programming and directive, oblivious to EVE, Hal, and his collection.

EVE attempts to help him remember, but when all her efforts fail, she becomes heartbroken and sadly holds his hand like he had wanted and gives him a farewell "kiss".

WALL-E has twin, extending, hydraulic arm shovels with articulated fingers mounted on U-shaped tracks to his sides.

All his extremities — arms, treads, and head — retract back into his cube-shaped body for easier storage, referred to as "boxing" in the movie script.

As such, he is able to survive most environmental dangers, including long falls, extreme heat, the vacuum of space, and being trapped in a hydraulic actuator much larger than himself.

When she shuts down after getting the plant, WALL-E places her on top of his transport (thinking she is charged by solar energy just as he is) and protects her from the weather waiting for her to "recharge".

As the film progresses however, WALL-E is able to understand the importance of how love isn't just about holding hands, but taking time to know each other, trusting people and accepting who they are and what they are meant for.

McMaster's four-foot robot made an appearance at the Walt Disney Family Museum and was featured during the opening week of Tested.com[18] a project headed up by Jamie Hyneman and Adam Savage of MythBusters.
