Ross Brimmicombe-Wood (Unbound Universe)

In the Unbound Universe, Colonel Ross Brimmicombe-Wood was the leader of UNIT, following a disgraced Brigadier Alistair Gordon Lethbridge-Stewart who'd retired from UNIT following a number of disasters. Even though he was a serving officer in UNIT, he didn't believe Lethbridge-Stewart's accounts of aliens, dinosaurs, and time travel because there was no evidence of it - instead viewing the man with contempt.

On 30 June 1997, he led a team to Hong Kong to retrieve Ke Le before the transfer of sovereignty. He resented the mission and showed nonchalance towards civilians who were distraught and did not care about the sanctity of the local monastery which he took over as his HQ.

After initially coming into conflict with the Doctor and Lethbridge-Stewart, Wood was convinced to ally with them after Ke Le, in fact the Time Lord known as the Master, unleashed a psychic parasite that fed on the aggression of Wood's soldiers. After the Doctor and the Master had made a bargain, the group left with the parasite for the waterfront so Wood's men could flee what was soon to be Chinese territory while the Doctor and the Master would escape in the Doctor's TARDIS to destroy the parasite. Though Wood led his men to the docks, they were delayed by the Master requesting sanctuary, the rescue boats leaving when midnight struck, leaving them stranded on Chinese soil. As Wood frantically called this in, the death of the parasite caused the Ke Le division to go mad and they opened fire on the area. (AUDIO: Sympathy for the Devil)

Behind the scenes

 * He was originally Colonel Singh, an English Sikh, but Jonathan Clements decided "a double-barrelled name was more appropriate - to accentuate the fact that he was the antagonist of the Brigadier, just as the Doctor is constantly at odds with the Master". He was made Scottish after Tennant was cast.
 * An alternate version of Ross Brimmicombe-Wood appears in the UNIT audio series. That version turns out to be a traitor for the Internal Counter-Intelligence Service, playing off the fact the audience already knew him to be a loyal soldier.
