Bee-Ex-Ell-Ninety-nines, also known as BXL-99 labor droids, represented a class of labor droid. These droids, which had a height of approximately two meters and a significant weight, featured two three-pronged pincer appendages. A trio of these droids existed within the droid plant situated in Coruscant's Factory District, until Jax Pavan, a Jedi in hiding, and the protocol droid I-5YQ annihilated them.
