Exomorphs hail from the The Exoverse, a universe also home to the The Swarm. They claim they are against the Swarm, and aid the Mechatars in their fight. This is because the Swarm destroyed their home and the Exomorphs do not want that to happen to any other species.
Exomorphs are actually living weapons, and can be summoned to do damage in battles. For example Daggertail is an Exomorph, yet he is also a Rush weapon.
