Two WALL•A units were encountered by WALL•E, M-O and EVE aboard the Axiom. They mistakenly compress WALL•E and EVE into garbage cubes ready to be flushed out the airlock. Little that they know that M-O has wedged himself between the inner airlock doors as the outer airlock doors open, causing air to flush out into space. At the same time, EVE , holding WALL•E , reaches out and grabs hold onto M-O in an attempt to save themselves from being jettisoned into space. The WALL•As take notice and shut the outer airlock doors, saving the three robots. They shine the light bulbs in their eyes as they observe the trio and wave goodbye as they watch WALL•E, EVE and M-O leave the garbage area. They are later seen back on Earth with other robots and humans when the Axiom has landed.
WALL-E video game
A single WALL•A unit blocks WALL•E's path on Earth in the WALL•E video game. WALL•E works with EVE to destroy the robot's heart. Two more units are later seen aboard the Axiom just as they are in the movie.
In the PS2 and PC versions, the WALL•As are used to get to the other side of the room.
- The WALL•A units are usually silent, but in a deleted scene, as one of them picks up the cube WALL•E made, they look at each other and make a purring noise.
- When asked on Twitter why no WALL•A type robots were present on Earth, Andrew Stanton replied, "Just [because you] don't [see them] doesn't mean they're not there."
- In an alternate version of the garbage disposal scene, where EVE is the damaged robot that accidentally gets compacted, not WALL•E, WALL•E gets the WALL•As attention by demonstrating his own trash compacting cubes. Despite the obvious size difference with their cubes, the large robots show approval, give WALL•E a friendly pat on the head (which nearly buries him), and continue their work, resulting in WALL•E having to save EVE.
