The R3-series Astromech Droid is a successor to the popular line of R2 astromech droids with faster processing abilities designed to fit in the droid socket of any starfighter. It is commonly designed with a domed or tapered code head, with a cylindrical core in addition to a base, retractable tread leg and two main legs. It has multiple appendages and attachments within its compartments, such as shock prods, welding torches, and is equipped with a holoprojector.
Artemis has been altered to appear more as a token of wealth than your typical R3-series Astromech Droid. Silver paint has been applied to the droid's exterior, allowing for accented gold plating in order to create a contrast and draw attention to the supposed credit value the droid represents.
Artemis has developed a quirked personality, granting it an inclination towards heavy doses of sarcasm when engaged in dialogue. As a result, Artemis comes across as having issues taking direction and developed a reputation for 'snark'.
Artemis has had most of the factory installed safety limitations on operation removed, both in the hardware and software, allowing this R3-series Astromech Droid to perform acts at the limits of its physical capabilities. This can make the droid stronger and more resiliant than a standard R3-series Astromech Droid, but at great risk to the droid itself or others.
