The GX1-series battle droid was created by Trang Robotics, after the success of their Duelist Elite droid. Trang Robotics then offered to create a battle droid based on their financiers' feedback and needs, resulting in the GX1. The droid was fairly large, hulking over an average-sized Human. With four arms - two strong and bulky and two smaller ones capable of fine manipulation - and a large blaster rifle incorporated into its head, the GX1 was well designed for versatile combat. They could speak both Basic and Binary. They possessed sophisticated tactical routines, which allowed them to reevaluate a combat situation, unlike battle droids like the B1 battle droid. If faced with a flaw in their original tactics, they would regroup and launch a new plan of attack.
