Humans

Humans in the world of The Murderbot Diaries have a wide variety of skin, hair and eye colors, with skin colors tending toward shades of brown. (Usually only characters with particularly light or dark skin are specifically described.) Cosmetic treatments to change skin color are not unknown (Network Effect), but artificial changes to hair color seem more common. Humans can also be of various heights and weights.

Some humans have implanted augments.

Due to the wide availability of advanced medical technology, the human lifespan may be potentially 100 or more years, but little data is presented in the series about how long humans typically live, or at what age they are considered mature.
