Monster droid

Monster droid, also known as a junk droid, was the term used to describe any droid that was created by piecing together component parts of many other droids. 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 rampage, confuse orders, or even start building more of their own kind when having enough junk to do so. Though anyone with the know-how could cobble together a monster droid, they were most notably created by the various Jawa tribes on Tatooine. Because they mainly sold their wares to moisture farmers and small town businesses, Jawas knew what peoples' needs were, and were able to create custom droids to meet the individual needs of any customer.

Though no two "Monster" Uglies were exactly the same, they were generally constructed in four classes: The Mechano-droid was a heavy labor unit, designed for permanent installation inside a tech dome The Quad-pod droid was a four-legged cargo carrier The Rollarc droid was a four-wheeled multipurpose unit suited to variable tasks The Tracto-droid was a tank-treaded mobile scanning/radar unit
