Although part of the R4-series of astromech droids, R4-P22—and all other Jedi Temple astromechs—were based on Obi-Wan Kenobi's droid, R4-P17, which had an R2-style dome rather than the usual conical head dome.
R4-P22 flew with Anakin Skywalker during the Battle of Muunilinst, but was destroyed on the surface of Yavin 4 when Asajj Ventress destroyed his ship.
Skywalker's wife, Padmé Amidala, later presented him with her Royal House of Naboo droid R2-D2, which flew with Anakin for the rest of the war.
