When refugees of Earth settled into the First Residential Colony on Amaari, they began to scavenge any bots, metals, and Artificial Intelligences they could find in order to rebuild their society. As a result, some machines ended up cobbled together a little less elegantly than others. Several years after settling in, a repair specialist discovered something unusual... A robot that had been repurposed to vend apple juice had formerly possessed a powerful, combat-focused AI.
The repair specialist brought it to the attention of local engineers. The engineers discovered a total of 7 robots with the same programming, but this apple juice vendor--labeled MBA-07--turned out to be unique in both its human-like capacity for emotions and its ability to interact directly with SOL. As a result, the AI was transferred into a battle bot chassis and equipped with Master weapons. The engineers intended to study it, suspecting it may provide insight into Atlas. So far, though, MBA-07 seems too terrified of conflict to provide many clues.
