Dalek Jast

Dalek Jast is Dalek Sec 's right-hand man (well, right-tentacle man)

He is a tactical genius and is just as ruthless as any Dalek. He also pairs up with Dalek Thay as advance scout assault Daleks when the Cult go on their crazy missions.

When the Cult of Skaro was a first established, Dalek Jast was just like any other Dalek. However, when the Cult of Skaro's original fourth member, Dalek Rabe, was killed, Jast was commissioned to take over from him.

Jast aided the Cult in their many missions, and fought against the Cybermen during the Dalek-Cyberman war. He survived the battle and escaped with the rest of the Cult to 1930s New York, where he joined Caan's rebellion against Dalek Sec.

He was killed by Dalek-Humans after they got angry when Dalek Sec was killed.
