EV-A4-D, also known as A4-D, was a modified EV-series supervisor droid who served the cyborg General Grievous of the Confederacy of Independent Systems as a medical/repair droid during the Clone Wars. As with many EV-model droids, a programming defect caused EV-A4-D to have a sadistic personality. Prior to his work with Grievous, EV-A4-D served as a supervisor in a hospital on the world of Tauber, but he was relieved from duty after ordering the medical droids under his command to operate on patients without administering painkillers. He was later purchased by the InterGalactic Banking Clan and absorbed into the Confederacy of Independent Systems.

EV-A4-D was eventually assigned to work as the personal doctor of Grievous. Stationed in Grievous's castle on the third moon of Vassek, EV-A4-D became the facility's caretaker, managing the general's residence and working to repair any damage he sustained to his cyborg body over the course of the war. Around 22 BBY, Confederate Head of State Count Dooku lured Republic forces to Grievous's castle in order to assess the general's abilities as the Supreme Commander of the Separatist Droid Army. During the confrontation with the Republic, Grievous was heavily damaged and was repaired by EV-A4-D to be able to confront the intruders once more. EV-A4-D later separated Nahdar Vebb and Kit Fisto, the two Jedi who were leading the Republic forces, allowing Grievous to defeat Vebb. However, as EV-A4-D monitored the castle's security cameras from the control room, he was bisected and destroyed by Fisto.
