(I know this more of a Gundam profile but the ELS can still br played like normal.)

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 of all things; being one with what they don't know allows them to understand. The ELS has no true form as they are capable of taking any shape or size relative to their mass. They can combine or separate from one another to increase or decrease its mass as needed. When faced with an opponent or something unknown, the ELS can assimilate and convert the target of interest into an ELS. It is shown in the movie that the ELS tend to target beings that emit Quantum Brain Waves, such as Super Soldiers, Innovades, Innovators, or humans that show potential of evolving into Innovators.

When confronted with unknown organic lifeforms or technologies, the ELS assimilates the target like an aggressive virus. Its rapid adaptability and versatility allows it to take hold of technology in a matter of seconds and organic matter in a manner of minutes. However, for organics, it can have detrimental effects to those not completely assimilated, such as causing brain damage (Setsuna F. Seiei) and various biological instabilities due to their invasive nature to their condition. While their complete nature is not understood, it is understood that they can utilize quantum brainwave frequencies, make copies of what they have assimilated, and utilize their own GN technology. GN Particle emitted by the ELS are colored purple. However, it isn't clear if this is due to their own development and evolution or from copying pre-existing technology. The ELS also are able to develop countermeasures against enemy forces, as shown when the massive ELS superstructure utilized a beam refraction barrier to counter the CB Mothership's 80m GN Laser, and even the Quantum Sword of the GNT-0000 00 Qan(T).

The ELS assimilation process can come in two different ways. One is where an ELS attaches itself to a MS or a living organism and stays attached, appearing as large metal shards covering the infected target. The second way is an actual merger with the target, appearing as a mercury-like substance covering the target. Sometimes, the fusion of an ELS to a target can results in the innovation of humans, as seen with Gundam Meister Leonard Fiennes, Graham Aker and civilian Amia Lee. A person fused with ELS has a paler skin tone and their hair is more silver in color, though the skin tone may vary depending the amount of melanin a person has in their body. During his 50 years with the ELS, Setsuna F. Seiei was most likely completely assimilated by the ELS, resulting in the same effects as described, but also giving his body a metallic shine. Setsuna is so far the only person to have undergone complete assimilation by the ELS.

The ELS also have the same effects on mobile suits. The ELS can fuse with MS and modify them. Examples are seen when the ELS merge with the damaged GRM Gundam, and give the suit a more curved design. Interestingly, the GRM is still able to use Trans-Am, indicating that its GN Drive Tau was not assimilated. This is in contrast to the ELS GN-XIV, where the ELS were unable to use Trans-Am due to their physiology despite the original GN-XIV's being able to do so. The GNT-0000 00 Qan[T] was also upgraded by the ELS, sporting new armor (which was discarded via the Quantum Burst) and wings that may be its modified GN Sword Bits.

Classes of ELS

Small ELS

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

Medium ELS

Less common than Small ELS, the medium ELS are roughly the same size as space battle cruisers, and target battle cruisers or large MAs such as Gadelaza. However, any mobile suits caught within the path of medium ELSs will be instantly assimilated, as opposed to being slowly assimilated by the smaller ELS. They take on similar structures as jellyfish.

Large ELS

Only one large ELS was present in the movie, and that was the one that was spherically shaped, roughly the size of the moon. It served as a base of sorts to the ELS, and was capable of assimilating planets, and even deflecting the 80m grade GN Laser Cannon from the Celestial Being Mothership on the second shot.
