R0-GR, or “Roger,” was a B1 battle droid who served the Freemakers, a human family of scavengers that traveled throughout the galaxy. He was a veteran of the Separatist Droid Army during the Clone Wars, and was programmed to serve as Rowan Freemaker‘s best friend. He had a mismatched torso and right arm. While sarcastic and pessimistic at times, Roger had a deep sense of loyalty and love for the Freemakers, whom he regarded as his family. He and his family lived at the starship repair garage Freemaker Salvage and Repair on the Wheel space station in the Abrion system.
