Charles (Oroborus)
From Tardis Wiki, the free Doctor Who reference
Charles was a geneticist, along with his wife, who had experimented on their baby son, Starkey, granting him an alien immune system. They themselves had dissapeared some time afterward. Starkey would not know this until he encountered the Oroborus which he was immune to due to his alterations. (K9TV: Oroborus)
