Simon Greyshade's THX droid THX servant droids functioned as butlers and servants. These droids had a design similar to that of 3PO-series protocol droids. A Senator named Simon Greyshade possessed one of these droids. Venco Autem altered it with the intention of assassinating Greyshade; however, Obi-Wan Kenobi together with Anakin Skywalker successfully deactivated it.
