Exo
Exos are robotic creations that were made as a pet project in the UNSC Navy but the only ship that possessed Exos was the UNSC Wayward Son, but it was common in residential areas and some ONI facilities to have Exos as vendors or builders, even guards. They have been in commission since 2522, yet only 34 Exos are active in military service. Most have been scraped or been repurposed for civil duties.
