The beginning: Edit
R4D BO1 was a cleaning droid stationed at Cloud City. He was one of the first cleaning droids at Cloud City to actually be programmed with more advance A.I, thus giving him a wider range of knowledge and a personality. Unfortunately, this came with a downside as R4D BO1 turned out to be quite possibly the biggest robotic cunt stain to ever erect his metallic dong in the galaxy.
One day, one of the maintenance guys up at Cloud City must have become extremely fucking bored, and we mean REALLY fucking bored because for what ever reason he decided that tampering with the circuitry on one of the cleaning droids was a good idea. The cleaning droids were usually mindless drones who would do nothing but endlessly mop the fucking floors so they remained constantly shiny and new that way everyone's OCD boners didn't get cockblocked.
The maintenance guy fiddled around with R4D BO1's wires (and probably his own 'wires' too) and soon managed to add further adjustments to the machine. He turned R4D BO1 off and then on again to see if his improvements had actually worked (anything to boost his already declining ego) but all he was greeted with was a swift "FUCK OFF YOU CHEEKY SHIT HEAD I WILL REK U" from R4D BO1. This was followed with R4D BO1 delivering a quick punch in the nuts to the maintenance guy before stealing a ship and flying off to find new adventure.
Galactic Civil War: Edit
It turns out that R4D BO1's artificial intelligence wasn't as intelligent as originally thought, considering the fact that he forgot that most, if not all, ships need a certain amount of fuel to get from point A to point B. Anyway, he crash landed on a remote planet in the middle of fucking nowhere. Needless to say, the impact of the crash fucked R4D BO1 up, so much so that he briefly deactivated.
For many decades he remained in the damaged remains of the ships completely deactivated. It was at this point that an adventurer, the now legendary Chewkok Numdik, landed on the planet after an extremely fucking epic battle with the empire's forces and discovered him.
Numdik was unsure what to do with the droid seeing as he was at this point in time now considered 'out dated' technology (he was basically a really shitty droid), not to mention his past prospects include being a fucking cleaning droid. Numdik decided that he was too much of a piece of shit to bother repairing and proceeded to leave.
Just as he was planning to leave, an imperial officer fucking upper cutted the cunt, he was knocked out cold.
