R4-M6 was an R4-series astromech droid socketed into Mace Windu's Eta-2 Actis-class interceptor. He was destroyed during the Battle of Coruscant, after Mace Windu collided with a fleet of vulture droids and droid tri-fighters, and was forced to jump out of the ship, abandoning him. R4-M6, like R4-P17 (and few other astromech droids owned by Jedi), was modified with the head of an R2-series astromech droid.
Behind the scenesEdit
Hasbro made an action figure of R4-M6 in 2006.
