Biography
The First Doctor knew him at the Prydon Academy. He (supposedly) called Vansell by the nickname of 'Nosebung'. (BFA: Neverland) Vansell belonged to the Deca, a clique of young Time Lords and Ladies which included the Doctor and the Master. Like Ushas and Rallon, Vansell did well for himself and received his Rassilon Imprimatur before the Doctor. Vansell had already joined the CIA despite his youth and followed their orders to watch the Doctor closely. (PDA: Divided Loyalties)

Angered because he believed the Sixth Doctor had let the Nestene Consciousness escape destruction by the Time Lords, he set up his trial on Space Station Zenobia (PDA: Synthespians™) The jury would subsequently acquit the Doctor of the charges. (DW: The Ultimate Foe)

He accompanied the Lord President of Gallifrey to the Planet Archetryx for the Archetryx Convention in the use of Time travel capabilities of other race, such as the Monan Host and Andromedans, but he had another motive there, which The Doctor disliked, of looking and taking any advancements that the other temporal powers had applied to there time machines, and having the CIA addapt them to Gallifreyan TARDIS. During the attack from the Daleks he helped to defend Archetrix and was surprised that the Vagoyans helped. He escaped with the Lord President, and left The Doctor, Evelyn and Lady President Romana II fighting the Daleks when Etra Prime collided. When the Daleks approached Gallifreyan space, disguised as Monan time vessels, he allowed the Transduction barrier to be lowered an allowed the Daleks to invade Gallifrey. He helped the Doctor to defeat the Daleks and stop them from destroying the universe with the Apocalypse Element. He was angry that the Doctor erased most of the security system's retina scans and replaced it with only Evelyn's, however he came round when it ment the Daleks didn't kill to many Time Lords. (BFA:The Apocalypse Element)

Vansell led a Gallifreyan Time Station on an expedition into the world of Anti-Time to find what he believed to be the body of the Time Lords' revered founder, Rassilon. He was possessed by anti-time energy, and attempted a coup over Madam President Romana. With her help, Vansell overcame the anti-time influence and trapped a group of Neverpeople (along with himself) inside the Time Station's temporal reactors. He and the Neverpeople were vapourized by the temporal energy of the reactors. (BFA: Neverland)

He was succeeded as coordinator of the CIA by Narvin. (BFG: Weapon of Choice)

Alternative versions
In an alternative timeline, he first tried warning the Doctor from enabling the Knights of Velyshaa to conquer Gallifrey, then when that failed, attempted to kill him. (BFA: The Sirens of Time)

In another alternative timeline, he was a lowly servant of the House of Heartshaven, Lady Romana's ancestral home, who was secretly in the employ of her son Antonin. (BFG: Reborn)
