EV-A4-D

**EV-A4-D**, also known as **A4-D** or **Ay-Four-Dee**, was an EV-series medical 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. In 21 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 decapitated and destroyed by Fisto.

The droid's body was later recovered by Grievous and reassembled. EV-A4-D then left Vassek, traveling with his master during his military campaigns serving as both doctor and advisor. EV-A4-D was present alongside Grievous during the siege of Dorin, during which he informed the general of a communication from Count Dooku's assassin, Asajj Ventress. EV-A4-D continued to serve Grievous until the end of the war.

During the Imperial Era, EV-A4-D was incarcerated at the prison known as The Prism. Somtime after the Empire's fall, the bounty hunter Boba Fett sprung EV-A4-D from prison, being on a mission to recover modules belonging to the *Malevolence* that were supposedly among the wreckage of the massive ship on the Dead Moon of Antar. Fett had been told by his client that EV-A4-D would be a source of help for him on his mission.

## History

### Imprisonment and escape

In 7 ABY, A4-D was being held as a prisoner at The Prism, having been imprisoned there years earlier by the now fallen Galactic Empire. He served as a medical droid for other inmates during his prison sentence, occasionally working on shifts in the prison's medical facility. One day that year, Boba Fett came to the prison looking for the droid, as Fett's client had told the bounty hunter that EV could be useful on his mission. Hacking into the prison's command controls, Fett released all of the remaining prisoners so he could find A-4D more easily. During the ensuing firefight, an astonished A4-D watched as the incredibly dangerous prisoners attacked Fett.

After Fett fought off and defeated the inmates, he went to A4-D, saying that he was taking him along. The droid asked why, and Fett told him that he was on a mission to recover parts from the remains of the *Malevolence*, and that his client, TA-175, had said that A-4D would be a useful source of help on the mission. The droid accepted, and he and Fett went aboard Fett's ship, *Slave I*, departing The Prism. As Fett flew through the raging electrical storms of Diab during their departure, A4-D stated to the bounty hunter the odds of successfully navigating and surviving the storms, which were very low, but Fett told him to shut up and not tell him the odds. Ultimately, they succeeded in making their way through the storms, leaving the Diab system and making the jump to hyperspace.

*Slave I* later dropped out of hyperspace at the Dead Moon of Antar, going to the exact spot where the *Malevolence*'s wreckage was located. After they landed, Fett and EV-A4-D disembarked, and immediately started searching the rubble for the modules that they were seeking. They found computer parts which originated from Kynachi, and also some schematics/blueprints of the *Malevolence.* Fett examined those parts, and realized they were the parts that he was looking for. Then, Fett and A-4D returned to *Slave I*, their mission successful. As they traveled through space in *Slave I*, EV requested that Fett drop him off on Innton II. Fett complied, making the calculations for a hyperspace jump to Innton II.

### Left behind on Innton II

After they arrived Innton II, Fett asked A4-D where he wanted to go, and the droid said he wanted to stay on the planet. Suddenly, they then encountered Mace Windu, the Jedi who had killed Jango Fett, Boba's father, over twenty years before. Windu had survived his confrontation with Darth Sidious in 19 BBY and subsequently went into hiding in the Outer Rim. A-4D then watched excitedly as Boba and Windu fought against each other, watching their fight in a similar way to how he had watched the duel between Grievous and Nahdar Vebb years before. After the duel, in which Fett almost defeated Windu but let him live due to his code of honor, A-4D watched as Fett departed Innton II in *Slave I*. The droid regarded Fett and Windu dropping their long-standing feud as "boring." Fett later delivered the modules EV-A4-D helped him recover from the wreckage of the *Malevolence* to TA-175, receiving his reward.

## Characteristics

Similar to other EV-series supervisor droids from MerenData, EV-A4-D displayed a cruel personality. While successful in increasing the productivity and efficiency of the medical droids working on Tauber, EV-A4-D's practices concerned the organic doctors he worked with. His methods eventually led to his dismissal when he ordered the medical droids to refuse painkillers to the hospital's patients, causing needless pain for the individuals that the hospital meant to help.

With the transfer to Grievous's Vassek castle, EV-A4-D's high-level abilities as a supervisor and taskmaster went unused, as his responsibilities were limited to housekeeping and the management of a small force of MagnaGuards. EV-A4-D grew bored with his work and wished for excitement—a wish that was granted with the arrival of Fisto and Vebb. Although normally highly attentive, EV-A4-D became careless during the intrusion, losing track of Fisto and realizing only too late that the Jedi was directly behind him, prepared to strike.

During his service to Grievous as the cyborg general's personal doctor, EV-A4-D developed an uncommon relationship with his patient. Although normally unwilling to tolerate insolence or disrespect, Grievous endured the droid's criticism of his abilities and demands during repairs. Although A4-D worked diligently to ensure quality repairs, the droid enjoyed the opportunity to inflict pain upon the Kaleesh during his reconstructive surgeries. EV-A4-D was curious of the reasons behind Grievous's physical transformation and took care in ensuring his work on the mechanical body would not go to waste, insisting that Grievous take time to rest after his repairs. The droid was delighted at Grievous's prowess during his duel with Vebb, cheering him on moments before he was bisected by Fisto's attack. When EV-A4-D watched Boba Fett fight Mace Windu, he was delighted, cheering Fett on. However, when Fett decided to not kill Windu and then both combatants decided to end their long-lasting feud, the droid was bored by it, his excitement having left him. When Fett flew *Slave I* with A4-D in it through the electrical storms of Diab during their escape from The Prism, the droid quoted the odds of surviving, only for Fett to interrupt and defy them as he was a hardened man who survived many deadly situations in the past.

While most of EV-A4-D's bronze-colored body resembled that of other EV-series droids, EV-A4-D possessed modifications that allowed him to serve as Grievous's doctor. A small attachment that hung over one of EV-A4-D's white photoreceptors housed his logic center. Several arms that were attached to his torso and back had medical instruments affixed to the ends, while one of EV-A4-D's primary upper limbs was affixed with a "carousel arm" that allowed for rotation at the wrist between a surgical laser and a precision gripper. Circulatory fluid used during surgical operations hung from a limb extending from the droid's back. EV-A4-D also had a supply palette attached to his waist and magnetized feet. He still retained all of his equipment while imprisoned at The Prism.
