B2EMO, also known as Bee-two or Bee, was a groundmech salvage assist unit that served the Andor family for years. The weary old droid used his many tools to tow scrap for members of the human family, including Cassian Andor, who eventually went on to join the Rebel Alliance. B2EMO was squat and boxy, a red machine with black sensors that used treads to travel towards his destinations.

B2EMO was a groundmech salvage assist unit who served with Maarva Andor. By 5 BBY, he still served Maarva and her adoptive son, Cassian Jeron Andor, on Ferrix.

B2EMO was an inquisitive droid, wanting to help Cassian in whatever way he could and being eager to learn about his activities. He bantered with Andor on occasion and was willing to do him favors to help cover up his dealings. When he and Maarva were detained by the Preox-Morlana authority, B2EMO was prepared to lie and not give away Andor’s location, who the soldiers were searching for. By 5 BBY Bee was experiencing malfunctions such as vocal stuttering and data lags.
