Bors (The Doctor's Meditation)
Bors was an Englishman living in Essex in the 12th century. When the Twelfth Doctor saved him from a splinter, Bors pledged himself to the Time Lord as a debt for the Doctor "saving his life."
Bors was with the Doctor while he was trying to meditate in a castle. Bors and his men began to dig a well on the Doctor's orders when he claimed the water they had wasn't good enough. It took them nearly a week to find water, and the Doctor suggested they build a visitor's centre once the well was complete, annoying Bors.
Bors was also able to solve the Doctor's magic trick, but admitted he still thought of himself as an idiot. He also noted that the Doctor was unable to meditate due to the fact he couldn't remain silent, but then listened intently as the Doctor told him about a battle field he had found which would be his last.

Bors later challenged the Doctor to an axe fight, to which he arrived playing the electric guitar and riding a tank. Enjoying the Doctor's presence with the crowd, Bors was strangled by one of Colony Sarff's snakes. He later located the Doctor's TARDIS for the Daleks, because unbeknownst to anyone, at some point he had been converted into a Dalek puppet and lost his free will. (TV: The Magician's Apprentice)
