John Jefferson
From Tardis Wiki, the free Doctor Who reference
John Maynard Jefferson was the head of security during the Walker Expedition. He was a brave man and always did what was right for his team. He was believed to be taunted by "the eyes of his wife" but still remained in his duty. When the Ood were possesed by the Beast, Jefferson had to sacrifice his life in order to save Rose Tyler and what remained of his team. (DW: The Impossible Planet / The Satan Pit)
