R4-M9 is an astromech droid from the Star Wars universe, best known for serving as the loyal starfighter support droid assigned to Padmé Amidala. The droid appears in Star Wars: Episode I – The Phantom Menace and helps with navigation, repairs, and ship maintenance during critical moments. Like many astromechs, R4-M9 has a practical, technical role rather than a combat one, but it contributes to the success of the characters it assists by keeping their ships operational and missions on track.
