WALL•E (Waste Allocation Load Lifter – Earth Class)The title character. WALL•E is the only robot of his kind shown to be still functioning on Earth. Although working diligently to fulfill his directive to clean up the garbage, he is distracted by his curiosity, collecting trinkets of interest. One day during work, he meets EVE and his life changes forever.
Voiced by: Ben Burtt
- Absurdly Dedicated Worker: He keeps trying to clean up Earth's surface after all humans have left even though he is the only robot still functioning and no real progress has been made in several hundred years.
- Adorkable: He loves musicals (well, one musical). He collects spoons and forks... and has just started a new collection of sporks.
- All-Loving Hero: Seems genuinely pleased to meet everyone he comes across, human or robot.
- The Aloner: In the beginning.
- Badass Adorable: Especially in the climax when he holds up the holo-detector despite being damaged by Auto's taser.
- Blithe Spirit: Everyone he encounters starts thinking differently as a result of it—maybe because he wakes them up from their trance or because he's so filthy they break their programming to clean him.
- Butt Monkey: Gets blasted at, crashed into, broken, and tossed into walls regularly.
- Collector of the Strange: He keeps a wide assortment of random trinkets that catch his fancy.
- Critical Annoyance: A low-pitched BEEP BEEP BEEP BEEP plays when he's about to run out of energy.
- Determinator: Did the same job for 700 years, held onto the ship back to the Axiom for no one knows how long simply because EVE was on it, and held up the holo detector even though he had very recently been electrocuted by AUTO and was still recovering from that.
- Cute Machines: He and EVE are even the page image!
- Desperately Craves Affection: Keeps a pet cockroach. When he meets another actual robot, he's so eager to make contact that he tries to befriend her despite her attempt to blast him.
- Dogged Nice Guy: To EVE, initially.
- Last of His Kind: All the other WALL•E units have shut down. (He scavenges them for replacement parts.)
- Leitmotif: "Put On Your Sunday Clothes" from Hello, Dolly! serves as a symbol of WALL•E's emergent personality, and later becomes the rallying anthem of the malfunctioning robots. The absence of this song on WALL•E's personal audio recorder is what convinces EVE that he Came Back Wrong.
- Love at First Sight: He falls in love with EVE the first time he sees her. Possibly justified in that EVE is the first living thing he's seen other than cockroaches.
- Masculine Girl, Feminine Boy: Feminine Boy to EVE's Masculine Girl, despite being a garbage robot.
- Nice Guy: Granted, he does troll MO a bit.
- Non-Action Guy: He's a garbage bot. The closest thing he would have to an offensive capability is a utility cutting laser, but he never uses it as a weapon.
- Not a Morning Person: He drags himself around like a human needing a cup of coffee, bumping into things and unable to put his treads on until he gets his morning sunshine.
- Official Couple: With EVE.
- Opposites Attract: With EVE.
- The Pig Pen: Not on purpose, but 700 years cleaning up garbage on a deserted wasteland hasn't left him in the best shape.
- Post-Kiss Catatonia: WALL•E completely freezes the first time EVE "kisses" him.
- Puppy-Dog Eyes: When they're reset to factory standard, it's highly disturbing. The return to normal is what signals that he's back.
- Robo Romance: With EVE.
- A Robot and His Cockroach
- Stalker with a Crush: Much nicer than most examples, but the trope still applies. They even brought it up on the Blu-Ray geek track. "He's got stalker charm!"
- Stalking Is Love: To EVE.
EVE (Extraterrestrial Vegetation Evaluator)A sleek robot who WALL•E meets during a day at work and has come to Earth looking for something. She moves using antigravity technology and is equipped with scanners, specimen storage and a plasma cannon in her arm, which she is quick to use. WALL•E falls in love with her the moment he sees her. Eventually, she warms up to him and falls in love with him as well.
Voiced by: Elissa Knight
- Action Girl: With her arm cannon and a general willingness to rush into a fight.
- Action Girlfriend: To WALL•E eventually. She defends him, carries him around, and rescues him when AUTO's minions start chasing them through the ship.
- Adam and/or Eve: The first robot WALL•E encounters after living alone for so long, and she is meant to find life and get humanity back to Earth.
- Arm Cannon: Her primary weapon. Also her main tool, it seems.
- Badass Adorable: Like WALL•E, but more so.
- Cute Machines: He and WALL•E are even the page image!
- Defrosting Ice Queen: At first, she only cares about her directive. She starts defrosting after her frustrations with it make her more tolerant of talking to WALL•E.
- Gaussian Girl: Her mostly white body gives her a very soft outline.
- Hair-Trigger Temper: It doesn't take much for her to use her arm cannon on something.
- Hot-Blooded: With that Hair-Trigger Temper of hers and that much determination to complete an objective, she would definitely qualify.
- MacGuffin Escort Mission: Her directive is to safely bring plant life from Earth to the Axiom's scanner.
- Masculine Girl, Feminine Boy: Masculine Girl to WALL•E's Feminine Boy.
- Meaningful Name: She is named after Eve, the first woman on Earth according to The Bible, because Andrew Stanton thought that WALL•E's loneliness reminded him of Adam, before God created his wife.
- Not So Above It All: At WALL•E's home, he hands her an egg-beater, and after figuring it out, she spins it so fast that it breaks. Her reaction? To quickly puts away the handle and try not to draw attention. She even starts to hum something while she waits.
- Official Couple: With WALL•E.
- Opposites Attract: With WALL•E.
- Robo Romance: With WALL•E.
- Trigger Happy: Responds to any movement by blasting it when she first arrives on Earth.
- Tsundere: She starts off only caring about the plant, but she warms up to WALL•E as the movie goes on.
- The Unpronounceable: To WALL•E.
- When All You Have Is a Laser Cannon: Her problem solving tree is something like "blast it with my arm cannon. Does it still need to be blasted more? [Y/N]"
M-O (Microbe Obliterator)
A tiny, obsessive-compulsive maintenance robot with rollers for hands who keeps Axiom clean. When M-O meets WALL•E and sees how filthy he is, he deviates from his normal routine and follows WALL•E, cleaning up behind him.
Voiced by: Ben Burtt
- Butt Monkey: He's dedicated to his job...no matter how much he's going to need repairs by the end of it...
- Catch Phrase: "[FOREIGN CONTAMINANT]"
- Inspector Javert: Come hell or high water, he will ensure the grungy trash compactor will not disrupt the sterile, germ-free environment of the Axiom. A benign example, as he's perfectly friendly to WALL•E once he does his job.
- The Napoleon: Smaller than most of the other robots, but leads the group of cleaner robot.
- Neat Freak: So much so that he breaks his programming to follow WALL•E throughout the ship and clean him.
- Super OCD: He does not tolerate dirt and would even cut through the other robots' designated paths to clean up WALL•E's tracks.
- When All You Have Is a Hammer: Even when M-O starts helping the heroes, he does this by cleaning, the only thing he can do, even when other things would be more useful.
AUTOAUTO is the autopilot. Shaped like a sailing ship's steering wheel, Auto units assist the ship's captain with his or her duties.
Voiced by: MacInTalk
- A.I. Is a Crapshoot: Inverted; the other robots are going beyond their programming while Auto is still following his directive.
- Anti-Mutiny: He is actually following his instructions by defying the Captain.
- Big Bad: The reason why the Axiom hasn't returned to Earth for all of these years is because of Auto's directive.
- Big "NO!": As the Captain turns him off.
- Completely Missing the Point: See A.I. Is a Crapshoot. CEO Shelby Forthright gave the order not to return to earth because it couldn't sustain life. The current Captain points out that that order no longer applies since the plant proves that earth can now sustain life. AUTO's response? "Irrelevant." AUTO was given the order not to return to earth, and will stay by that order even though the reason it was given has changed.
- The Computer Is Your Friend: He was given orders to safeguard humanity, and he will fulfill those orders whether the humans want him to or not.
- Creepy Monotone: Combined with Evil Sounds Deep.
- Cyber Cyclops: He is one big red eye on a steering wheel.
- Evil Sounds Deep: He has a chilling, robotic baritone.
- Expy: Of HAL 9000
- Just Following Orders: He has the secret order (Directive A-113) to never return to Earth.
- "MUST FOLLOW MY DIRECTIVE."
- Knight Templar: "On the Axiom, humanity will survive."
- Psycho Electro: Shocks WALL•E with his taser to send him falling down the garbage chute.
- Red Eye, Take Warning: He has a red eye that deepens his similarity with HAL 9000.
- Villainous Breakdown: Starts when EVE and WALL•E break out of the trash pit. Exacerbated by Captain when he fakes out Auto with the plant backdrop. "Not possible" he says in monotone. Gets even worse when he starts sending significant numbers of Steward bots after EVE and WALL•E. Jumps off the slippery slope when he intentionally causes the Axiom to list, sending everyone tumbling about. Climaxes when he's using his taser to jam down the Holo-Detector retract button with excessive force.
- Walking Spoiler: He is first built up as just an auto pilot before A.I. Is a Crapshoot happens. Then he subverts it when he reveals that he has been following orders the whole time.
- Well-Intentioned Extremist: He honestly thinks he is doing good by not going back to Earth.
BURN-E (Basic Utility Repair Nano Engineer)BURN-E is the robot that is seen repairing the ship when WALL•E and EVE fly into the airlock and lock him outside. He's the focus of a short on the DVD with his name.
Voiced by: Angus MacLane
- Ascended Extra: Gets his own short.
- Butt Monkey: He's just trying to do his job and fix the ship, but the events of the film keep causing chaos for him.
- Lower Deck Episode: His short shows how his work spans the entire film.
- Shaggy Dog Story: By the time he finally gets it working, the light is destroyed again. And even if it wasn't destroyed, they're back on Earth by that point so it doesn't matter much anymore.
- Rule of Three: It takes him three trips to finally repair the light he's trying to fix.
Shelby ForthrightThe CEO of Buy n Large as of the exodus from Earth to clean up the rampant trash everywhere.
Played by: Fred Willard
- And Now For Something Completely Different: Hey Pixar, you got some live-action in your CGI...
- Word of God says this is because Fred Willard is like a cartoon anyway.
- Bigger Bad: He was the one who gave Auto the "never return to Earth" order that caused part of the main conflict later on.
- Posthumous Character: The movie takes place nearly 700 years after his enactment of Protocol A-113, so it's safe to assume he's long dead.
- Well-Intentioned Extremist: He put Protocol A-113 into place because Earth's environment had become toxic and he didn't want humans coming back to it.
Captain McCreaThe captain of the Axiom. His daily duties are so droll that he doesn't take them seriously... at first.
Voiced by: Jeff Garlin
- Acrofatic: For someone who has literally NEVER gotten any exercise, or even stood up once in his life, he sure has a strong grip!
- Big Good: He is leading the humans back to Earth, and he is opposed to Auto trying to stop them.
- Cowardly Lion: He reacts with loud shock whenever he sees something unfamiliar, like a dirty robot from earth, or a voice-activation mic. But he is surprisingly capable in an actual crisis.
- The Captain: "Auto... You are relieved of duty!"
- Crouching Moron, Hidden Badass: He starts as just another blob-person going through mindless routine. The prospect of returning to Earth wakes him up.
- Determinator: ""I am the captain of the Axiom! We are going home today!
- Only Sane Man: Seems to be the only human on board that is aware of the ennui of their existence.
- Authority Equals Asskicking: He's the highest-ranking (and perhaps only) officer aboard the Axiom, and manages to take down Auto in hand-to-hand fighting.
- Reasonable Authority Figure: He is a bit strict about protocol and routine, but not when the fate of humanity is at stake.
JohnOne of the passengers aboard the Axiom, and the first human WALL•E has probably interacted with on-board. He was entranced by the ennui of life aboard the Axiom before a chance encounter with WALL•E.
Voiced by: John Ratzenberger
MaryAnother passenger aboard the Axiom, also broken out of her trance by a chance encounter with WALL•E.
Voiced by: Kathy Najimy
- Beta Couple: With John.
- Mama Bear: When humanity prepares to return to Earth, Mary notices the panicking, crying babies and reacts in horror. Later, when AUTO tilts the whole ship and sends every passenger careening to its sides, Mary sees the falling babies, screams, "John, get ready to have some kids!" and throws him across the aisle to form a human net to catch them. What makes it even more powerful is that these aren't even her children—she's so much of a Mama Bear that she'll protect anyone's child, not just her own.
- Meaningful Name: John and Mary, huh?
