Harmonious 14 Zink

Harmonious 14 Zink was the companion of Zara during her early travels in the search for the Key to Time. He gave her the Time Ring he had picked up on Barampa; it was used by Zara all though her travels in the search. Harmonious was a brash person, who would kill to further his adventures. One example of this was when he killed an Ice Warrior on his way towards the capstone on the pyramid under construction on Mars. (BFA: The Judgement of Isskar)

He even was prepared to kill a whole planet to gain some capital, and tried to do so with Erratoon. Fortunately, this plan failed as the planet was prepared and all the inhabitants survived, including the Seventh Doctor's companion Ace. (CC: The Prisoner's Dilemma)

He was killed by another Ice Warrior after Zara left him. (BFA: The Judgement of Isskar)
