The LOM-series protocol droid, also referred to as a LOM-series droid, represented a model of protocol droid that was produced by Industrial Automaton. These droids were intentionally designed with insectile characteristics, mirroring the physical traits of the species they were originally intended to assist, the sentient Gand. Due to Cybot Galactica's dominance in the protocol droid market with their 3PO-series, the introduction of the LOM-series by Automaton proved to be a significant commercial failure; even Arakyd Industries' RA-7 protocol droid achieved greater sales figures.
A notable weakness existed within the LOM-series, making the droids susceptible to personality software corruption. Consequently, numerous LOM-series droids transitioned into enforcers operating within the Outer Rim Territories of the galaxy. For instance, 4-LOM, a LOM-series protocol droid, overrode its original programming to pursue a career as a bounty hunter. However, Andressa Divo, an agent of the ISB, began to suspect that the Droid Gotra orchestrated this programming alteration to provide a figurehead for their droid rights movement. Another LOM-series droid, known as 1-JAC, also functioned as a bounty hunter. Similarly, a LOM-series unit was in the service of Jabba Desilijic Tiure, a notorious crime lord. Furthermore, a LOM unit aligned with the Galactic Empire was stationed at Weapons Factory Alpha.
