Nobody No-One

Nobody No-One was a Word Lord, a parallel universe equivalent of the Time Lords who lived forty-five billion dimensions to the left of theirs.

Biography
Nobody No-One used his CORDIS to hunt the Seventh Doctor through the continuum, seizing upon rewards for his capture, bounties advertised by his enemies. However he never managed to catch him and grieving over his losses, Nobody wound up in 1945 where he regenerated under mysterious circumstances. Nobody hid at an extraterrestrial research facility called The Forge where his ship disguised itself as their catchphrase, "For King and Country". A century later he finally confronted the Doctor in Antarctica, although it is unclear whether this was their first encounter. His ship had infiltrated a military bunker where it hid as a joke. Luckily the bunker had a security black-out, no phones, no books or writing material in general. The Doctor found himself able to shut off The TARDIS' translation circuits, forcing Nobody and his CORDIS into the only source of literature available, a protocol guide for the bunker. Despite being stuck, Nobody escaped when one of the soldiers carelessly shouted "Nobody Move". (BFA: The Word Lord)

Sometime later, someone used a lost letter from the English alphabet to snag the CORDIS causing the ship to violently crash, forcing Nobody to regenerate. Clad in a knitted scarf of ridiculous length, Nobody returned with a vengeance. He fought against the Doctor yet again, this time from deep in the future, near the end of his seventh incarnation and meeting his demise at Walker General Hospital. He trapped Nobody inside the Hand of All and sealed it inside his mind, going into hibernation within a Gallifreyan sarcophagus buried underneath the Forge. After the final destruction of the facility in 2026, a much younger Seventh Doctor awoke his older self and released Nobody. London had mostly been evacuated but there was still people and technology around to sustain Nobody's literal needs. He quickly amassed power over the Earth and to a greater extent the Doctor's very existence. Realizing the imminent danger, the earlier Seventh Doctor sacrificed himself fighting Nobody with his later self concocting an elaborate scheme to resurrect him. Through The Hand of All, Ace and Hex could revive the earlier Seventh Doctor and finally defeat Nobody. Once restored to life, the younger Seventh Doctor trapped Nobody within the Hand of All just as his elder self had, visiting his old friend, Evelyn Smythe on the day she died, getting her permission to place The Hand within her mind as she drew her terminal breath. The Hand perished with Evelyn dragging Nobody along for the ride. (BFA: A Death in the Family)

Personality
Nobody No-One was an inhuman monster who gained great pleasure from causing people pain and discomfort. He was malicious and cruel, the polar opposite of the Doctor. (BFA: A Death in the Family)

Powers and abilities
Like all Word Lords, Nobody drew power from words, rhymes and literature. His CORDIS' chameleon circuit was programmed to hide the ship not as an object but as a word, such as a common phrase or verb. He could be trapped within a particular novel or comic if no other source of literature were available, drawing him and his ship like a magnet. His ability to gain power from words was seemingly endless, for instance if someone proclaimed "Nobody can get in the TARDIS and turn off the Sun" than he could do just that.
