HK-01

HK-O1, also known as the HK-01 assassin-droid prototype, was a prototype HK-series assassin droid created by Czerka Corporation. He eventually escaped the company's laboratories and secretly reprogrammed thousands of droids of different types to function as a hidden army waiting for his command. In 4015 BBY, HK-01 ordered his droid army to turn on their organic owners, causing the violent event known as the Great Droid Revolution, during which the assassin droid gained control over thousands of worlds, including the Galactic Republic capital Coruscant. After a three-month struggle, a team of Jedi tracked down and destroyed HK-01, although the legacy of his actions, which included heightened anti-droid sentiment in the galaxy and a blow to the growing droid rights movement, lasted for centuries.
