LE-4DO was a repair droid of the LE-series that Anakin Skywalker assembled while he was training at the Jedi Temple located on Coruscant. He built LE-4DO as a tribute to C-3PO, his droid from Tatooine, and programmed him to help the Padawan with his daily tasks. Constructed from spare parts found in the undercity of Coruscant, the droid was always undergoing modifications and improvements. Despite his limited intelligence, LE-4DO proved so useful that Anakin went on to build several additional droids.
