C4-H8

"''Greetings! I am C4-H8, Imperial protocol and espionage unit." ''-C4-H8 upon activation

C4-H8 was an Imperial espionage droid under the disguise of a 2V-R8 protocol droid unit. Its exact origins unknown, it was discovered by the Sith assassin Skiia, who became his new master.

Biography
It was unknown what originally occurred to C4-H8, as its memory was wiped completely clean upon discovery. The espionage droid had somehow made his way to Tatooine, where he was likely damaged or captured. Eventually, a junk dealer got his hands on the droid.

When Skiia arrived on Tatooine after crashing her family's former ship, the Starhawk, she sold the more valuable parts of the ship to a junkyard. However, the junkyard owner did not have enough credits to pay her fully, and said that she may barter the remaining pieces for something else in the store.

Initially deciding that she would just take what credits the store had and leave, she sensed a strange sensation and followed it to a simple-looking 2V-R8 unit. Trading the ship parts for the droid and a few credits, Skiia left the planet and took the droid to her master, Lord Carnifex.

Upon inspection, Carnifex discovered that the unit was actually an Imperial espionage droid. Using his knowledge of cybertech, he repaired the droid and "improved" his design, including implementing an experimental assassination protocol into the unit.

C4, now capable of both spywork and combat, accompanied his new masters to Ilum, where he aided in the Empire's victories on the planet. After Skiia and Carnifex retreated from Ilum, C4 accompanied Skiia again when she searched for Exar Kun's holocron.

Abilities
"Assassination protocol active. What is my target, master?" -C4-H8 upon activating his assassination protocol.

Originally a simple espionage droid with relatively the same knowledge database as an average protocol droid, C4's programming was altered by Lord Carnifex in order for the droid to serve more effectively.

Using elements from the HK-51 droid programming, C4 was modified to be a combat-capable droid, while still possessing his espionage skills. As a result, C4 became as proficient as any assassin droid, possessing deadly skill with blaster weaponry.

Moreso, C4's close-quarters tactics were personally implemented by Carnifex, a Sith Lord known for his skill with the lightsaber. As such, C4 gained a wide variety of skills with weapons such as vibroblades and techstaffs.

C4's original programming also enabled him to be an effective protocol droid, as he can translate many languages. On top of that, C4's function as an espionage droid meant he was also a capable slicer.
