Dalek X's name was famous across the universe, but it was not his real name; he adopted the title in the knowledge that it evoked fear in humans. It was every bounty hunter's dream to defeat him, but also every bounty hunter's fear to encounter him. He was often called "the Devil in Dalek form". He commanded the first Exterminator-class Dalek vessel, the Exterminator, and had a squad of Assault Daleks equipped with laser-cutting claws in place of manipulator arms. He had at least two elite guards, armed with double gunsticks. It answered only to the Supreme Dalek. It ordered the destruction of a flagship in the Auros escape fleet.
