- This page details the beings that existed in the Real World. For the reports of alien sightings and abductions within the Matrix, see Ethereal.
Aliens were beings of unknown origin. During the Machine-occupation of Earth and during the course of centuries, the Machines sent seed-probes to space. The aliens must have followed one of these back to Earth.
An alien spaceship arrived close to Earth and orbited the moon. The ship was massive, being the same size as Tasmania, and had two-hundred mile-long sticky tendrils which it used to transport and hurl asteroids to Earth. One such asteroid took out a central processing unit in London where 200,000 humans died. While London was disconnected from the Matrix, one of the bluepills - a huge Goliath of a man - found himself floating in a vacuum for a couple of nanoseconds during the short bout of disconnection. During this experience, he met a program, perhaps an Agent, who partially explained what was happening in the Real World.
To come up with a solution, the Machines used the Matrix and ran it at an accelerated rate. After a few years in Matrix time, but only within minutes in the Real World, the Machines started to counterattack and decided to alter the Matrix, resetting its recent history, and then training the Goliath into a PL-47 pilot within the Matrix while simultaneously building the spacecraft in the Real World. The man was then woken up to his pod in the Real World and was taken outside into his new ship. The spacecraft left Earth and the pilot victoriously destroyed the alien ship using the spacecraft.
The physical appearance of the alien beings were unknown as only their ship was ever seen; they likely had prior experience with and/or disdain for Machine intelligences, as all of their technology, including their spaceship, was organic. The ship was said to have resembled a fungus or seaweed and had a nucleus that functioned as an eye.
