Arrogant, careless, dramatic, self-absorbed, driven and stubborn, the Sixth Doctor instantly believed himself superior to almost anyone he encountered. Yet he also possessed a streak of cowardice and pessimism. He would often browbeat others into submission with his savage wit and his grammarian's interest in language. Even so, his mercurial and flippant tendencies did not define the the true heart of his persona. Beneath his thunderous and turbulent exterior, he was quite the opposite: a passionate, warm, virtuous and emphatic individual.

He was profoundly difficult with his first companion, Peri, whom he initially challenged for her use of American English and her as-yet-incomplete education. Indeed, during the early hours after his regeneration he also physically assaulted her, because the regenerative process had addled his mind to the point of paranoia. It took considerable time for himself and Peri to stop bickering and start behaving as genuine friends, but eventually the Sixth Doctor became someone she could rely upon.

Despite his bluster, the Sixth Doctor did possess great reserves of compassion. His gentler side began to blossom largely as a consequence of travelling with Evelyn Smythe, a university lecturer whose verbal dexterity was on a par with his own. Also helpful to this transition were Frobisher, a shapeshifting private eye who often masqueraded as a penguin; Melanie Bush, a brilliant computer programmer from late 80s; and Flip, a young woman from twenty-first century London. No matter the companion however, they always raised their eyebrows at his choice of attire. Bold, brash and overly complicated, his costume mirrored his own colourful personality.

A dominant feature of his life was yet another Time Lord trial. Though this one sought to blame him for a shifting docket of crimes, it in fact turned out to be an elaborate ruse. Already dying as a result of a previous adventure, the Doctor was forced to regenerate.
