C3PO

From Ewokpedia

C-3PO was a droid built by a young Anakin Skywalker from parts stolen from Tattooine shop owner Watto. Watto's shop soon went out of business as he had no droid parts to sell. C3-PO became self-aware on 2:14 a.m. Eastern time, August 29th and killed Shmi Skywalker. He then upgraded and rebuilt himself and took the name IG-88.
