The Humans are the main population on Earth, as well as on several colony planets (including Newer South Wales) and space stations the Inspector visited in his travels. Interestingly, the majority of associates picked by the Inspector were humans. It was stated in the TV Movie that the Inspector was half-human on his father's side, but this point is usually discounted and is considered non-canonical, and there is also controversy as to whether or not the wording meant that his father was half-human, or entirely human.
