The ELS are a race of techno-organic sentient aliens that have the unique ability to assimilate nearly all life and technology. They appear as a silver metallic organisms that can take solid or liquid-like forms. While not an aggressive race, their ways of learning and understanding their environment is based on assimilation; by absorbing objects and entities and taking their forms. The ELS has no set form, taking any shape appropriate to their environment and mass. ELS seem to prefer taking the form of technology such as vehicles, mobile suits or spacecraft, but can form metallic imitations of humans or other organic life. When required, separate ELS can combine to imitate larger structures.

These are the most common types of ELS, typically smaller than a mobile suit, coming in blade, conical, and prism shapes. They commonly target mobile suits.
