Star Wars: The Clone Wars (2008): 3x15

Overlords

A mysterious force draws Anakin, Obi-Wan and Ahsoka to a distant planet, and its inhabitants — a family of exceptionally powerful Force-wielders — in an attempt to determine whether Anakin is truly the Chosen One. The patriarch of this family, known only as the Father, has spent ages maintaining the balance between his Daughter, who is strong with the light side of the Force, and his Son, who aligns with the dark. The Father reveals his days are numbered, and he seeks Anakin to take his place as the fulcrum of this balance. A series of tests proves that Anakin is capable of controlling both offspring, as the Father does, but Skywalker refuses to take the Father’s place.
