Futu dynasty

The Futu Dynasty was an early Chinese dynasty that flourished around 5519 BC on Earth.

History
In 5519 BC, while China was still establishing a civilisation, Lin Futu, member of the Futu dynasty, was abducted by the Monarch and other Urbankans. He was taken to Urbanka with some of his fellow Chinese citizens and they were converted into androids. (DW: Four to Doomsday)

''The Futu dynasty did not exist historically on Earth. It is possible that it was a minor dynasty, of which knowledge was not passed down to the 20th Century.''
