The Son is the main antagonist of the Mortis arc in The Clone Wars. He personified the dark side of the Force and lived on Mortis with his father and his sister, the Daughter. However, the Son grew tired of his father's control over him and wanted to escape from the planet that became more of a prison than a home by attempting to corrupt Anakin Skywalker by kidnapping his Padawan, Ahsoka and showing him his future as Darth Vader.
The Son was later killed by Skywalker as the Father allowed the Jedi to end both their lives.
