R4-P17

R4-P17 is an astromech droid that accompanied Obi-Wan Kenobi in his Jedi starfighter on many missions, including the Battle of Geonosis in 22 BBY. She also accompanied Anakin Skywalker during his hunt for Asajj Ventress.

The Clone Wars
She received her R2-style dome after her original body was crushed while she was repairing the trash-compactors in the Kuat Drive Yards research shipyards orbiting Gyndine. Anakin Skywalker found her while he was inspecting the Jedi customizations of the Jedi starfighter modifications and he gave her her R2-series dome.

During the Clone Wars, R4-P17 had a new body which was like an R2 unit's body.

R4-P17's "life" was ended when her head was ripped off by a buzz droid during the Battle of Coruscant.

A New Life
After the Battle of Coruscant, R4-P17's body survived the destruction of General Grievous' capital ship. The body was found by Clone troopers after the crash on Coruscant. The body was taking to the Republic's droid factory to be rebuilt. Jedi Master Kenobi gave a data chip of all of R4-P17's abilities and memories to Industrial Automaton, the company responiable for making R4. R4-P17 was refitted into her third new body. Life took a turn for the worse when the Clone Wars ended and Order 66 came into effect. R4-P17 stationed at the Jedi Temple during the Great Jedi Purge led by Darth Vader. R4 took the liberty of setting up traps though out the temple, however it proved to be little effective, the Jedi were massacred. R4-p17 went into hiding as all other droids was being reprogrammed to serve the new Galactic Empire.
