The Doctor who started it all, Hartnell was a strange and mysterious character. Like all the Doctors that followed, he possessed great scientific knowledge, but, unlike most, he hated humans. More often than not, the first Doctor was crass, rude and patronizing to any humans he encountered. He often refused to help those who were in trouble, claiming that it was not his problem. In fact, the only person whom the first Doctor adored was his granddaughter, Susan.
Susan represented the Doctor's “humane” side and often coaxed her grandfather into helping out despite his protests and reluctance. Over time, his attitude slowly began to change, as he bonded with his time-traveling companions and began to enjoy his adventures a bit more. It was also during this Doctor's tenure that the show's most enduring and iconic adversaries, the Daleks and the Cybermen, were introduced. These mighty foes would go on to fight the Doctor's every incarnation in an attempt to “exterminate” him or “delete” him from existence.
