R4-P17 is an NPC, an astromech droid who co-piloted Obi-Wan's ship to Kamino.

Silence of the Clones Edit

When Obi-Wan found out that the Kaminoans were creating a clone army, supposedly for the Jedi, and that the army was being cloned from Jango Fett, a man who was vowing revenge against Obi-Wan, the Jedi, and the whole Republic, he asked R4-P17 to contact the Jedi Council. R4 contacted R2-D2, who was able to relay the message to the Jedi Council.
