4A-7 was an early RA-7 protocol droid prototype manufactured by Arakyd Industries on the planet Mechis III. He had the body of a Cybot Galactica protocol droid and an over-sized head containing surveillance equipment.
4A-7 with its mistress, Asajj Ventress, on Teth.
4A-7 was stationed at the B'omarr Monastery on Teth, alongside Asajj Ventress, who considered the droid her only friend. When Anakin Skywalker, Ahsoka Tano, and the clone troopers of Torrent Company arrived at the monastery, 4A-7 claimed he was the caretaker of the structure, and tried to make the two Jedi believe he was grateful.
After a holocam recorded Skywalker and Tano rescuing Rotta the Huttlet, 4A-7 doctored the image so that it made it seem like the two Jedi were kidnapping the baby and planning Jabba the Hutt's assassination. This recording was shown to Jabba by Count Dooku on Tatooine.
4A-7's treachery is discovered.
When the two Jedi, Rotta, and R2-D2 were preparing to flee Teth aboard the Twilight, 4A-7 appeared at the boarding ramp of the ship. He was decapitated by Tano after he was discovered to be in league with the Confederacy.
The droid was brought back to the Jedi Temple by Ahsoka so information could be retrieved from its memory core. A Jedi Knight was tasked with cracking the droid.
