William Abberton or Nimrod, was the head of the Forge from its creation through to its fall.

Biography
On 14th October, 1914, while experimenting on humans with a vampire virus for the Forge, the vampires overpowered their creator, and escaped. Abberton was mortally wounded in the process and took the drastic step of using the Twilight formula to save his life, becoming a vampire in the process. (BFA: No Man's Land, Project Twilight) Abberton then took the codename 'Nimrod' and, enhanced with cybernetics and specialized weaponry, sought to hunt the vampires down and destroy them. During this time he met the Doctor and Evelyn Smythe, who prevented him from killing the vampire Cassandra Scholefield. (BFA: Project: Twilight)

Between 2002 and 2004, Nimrod headed Project Valhalla, trying to scavenge alien technology from a crashed alien spaceship in Lapland. The mission turned into a disaster and the area had to be sterilised when the ship turned out to be a prison for a world-killing blood-formed entity known as Nyathoggoth. Following Vahalla, Nimrod replaced Crichton as Deputy Director of the Forge as he had Crichton assassinated. (BFNW: Project Valhalla)

Nimrod encountered the Doctor again in late 2004, while aggressively acquiring a Huldran spacecraft, he also initiated Project Lazarus: an attempt to replicate his regenerations. While the Doctor escaped, Nimrod had enough DNA information to create a clone of him; it was unable to regenerate, but had enough of the Doctor's attributes to be hired as a scientific advisor. When the Huldrans began attacking the Forge in retaliation, Nimrod had the clone brainwashed to believe he truly was the Doctor, had been stranded on Earth, and was assisting them to prevent the Huldrans destroying Earth.

By 2007, the constant Huldran attacks and the arrival of the seventh incarnation of the Doctor caused several key Forge members to realise the truth of the clones existence. While the Doctor solved the Huldran situation, the clone activated the Forge base's self destruct program. (BFA: Project Lazarus)

The Forge's beta facility was bought online soon after by Nimrod and he was the only known senior officer left alive. Torchwood 3 knew that Nimrod was still running the Forge through 2009. (REF: The Torchwood Archives)

By 2025 he began using the name William Abberton again. Abberton attempted to turn the Doctor's companion Hex against the Doctor by revealing the Doctor's involvement with the death of Hex's mother, Cassandra Scholefield. After the Doctor initiated the self destruct of the last Forge base, Abberton was disintegrated by an alien device. (BFA: Project Destiny)
