Junk droid

Junk Droid was a common designation for various self-made droids, created from leftover spare parts. Because of their mashed-together programming they were considered dangerous by most civilized people, for they could go on a ranpage, confuse orders, or even start building more of their own kind when having enough junk to do so.

History
After the Clone Wars many groups turned to recycling, rebuilding and repurposing the enormous amount of broken high-tech machinery left on the ravaged battlefields and on the junk worlds such as Raxus Prime. These junk droids were build out of almost any spare droid and vehicle parts and permorming a large variety of tasks. They could be roughly divied into three large categories: regular, brute and behemoth droids. Regular droids, fairly fragile and often equipped with shields, were approximately Human size and shape and generally used for common labor tasks. Brute droids were larger, stronger and solid rather than flexible and used as brute-force bodyguards or beasts of burden. Special-buile behemoth droids served as walking power plants or armor carriers. Junk droids were fairly common right after the Clone Wars, but as the supply of high-tech components decreased, so did the population of junk droids.
