Mechanoid Queen

A Mechanoid Queen was the leader of Mechonoid Empire.

When the Dalek Restoration Empire fell to the Entity, the Emperor of the Restoration came to Mechanus, proposing an alliance to the Queen. Taking the Emperor to the city's star chamber, the Queen reviewed the progress of the Entity before Mechanus' defence grid began failing. When she questioned her opposite, the Emperor revealed that he had deliberately led the Entity to Mechanus. (WC: Planet of the Mechonoids)

After Mechonoids returned the Entity back to the dimension it came from, the Queen allowed the Dalek Emperor to escape Mechanus. She promised that the Mechonoids would return and bring an end to the Daleks. (WC: The Deadly Ally)
