R4-G9 was an astromech droid owned by Obi-Wan Kenobi. Kenobi replaced the droid R4-P17 with this droid when R4-P17 was destroyed by buzz droids in the Battle of Coruscant and traveled with it to Utapau for the Battle of Utapau. Obi-Wan sent R4-G9 back alone in his interceptor to the Vigilance report to Commander Cody.
