R2-RN8W was a droid of the R2 series, specifically an astromech droid, and was distinguished by its rainbow-colored exterior. After the fall of the Galactic Emperor Palpatine in 4 ABY, it enjoyed celebrating with others on Coruscant, a planet located in the Core Worlds. Found on its dome were primary photo receptors, radar eyes, a data card reader, and a Herner optical holographic projector.
On the front of its chassis were a Burtt acoustic signaler, system ventilation, a hi-powered recharge coupling, and heat exhaust. Constructed from durasteel, its legs incorporated motorized treads; the right leg also featured a system lubricant filter/reservoir, an accentuating coupler, and a hydraulic arm shaft. A retractable leg was positioned in the middle, while the left leg included a quick-release fuel system latch. A cargo compartment was located on the droid's back.
The creation of R2-RN8W was specifically for a Disney Parks–exclusive figure, as part of the Star Wars: Droid Factory toy line. Its release occurred in 2021 and was part of Disney's Rainbow Collection.
