Vansell (He Jests at Scars...)
A version of the Time Lord Vansell appeared in a timeline in which the Valeyard, a future incarnation of the renegade Time Lord known as the Doctor, triumphed over the Sixth Doctor in the Matrix.
He expressed his fascination with the Valeyard, calling him a "unique being" and an "essential case for study". He initially wanted to allow the Valeyard complete freedom and use him to manipulate time the way the Time Lords had tried to use the Fourth Doctor to prevent the creation of the Daleks. Even when the Valeyard began to cross the line, Vansell refused to take action to stop the deranged Time Lord.
However, after seeing the Valeyard destroy Gallifrey, trapping Vansell and the interim Lord President in the Matrix on Space Station Zenobia, he had a change of hearts, and he and the Lord President gave Mel Bush their time ring and staser, sending her out to either try to connect with the Valeyard as the Doctor, or kill him though it was very nearly too late for him to take real action to stop the Valeyard.
Ultimately, Mel failed to stop the Valeyard in time, and Vansell and the Lord President both presumably perished in the decaying Matrix. (AUDIO: He Jests at Scars...)
