The history of the human race was given in bits and pieces throughout the series. A number Furons discovered Earth, mated with humans, and, as a result, led to humanity being endowed with Furon DNA. Thousands of years passed as humanity became more advanced. Humanity was rediscovered in 1959, as a party led by Orthopox in search for Furon DNA. Furons infiltrated human society, and since then slowly towards collecting DNA. A few human organizations, such as Majestic, the KGB, and Colonel Kluckin's Kitchen, took notice of the Furons and fought back with little success.
Humans were bipedal primates with varying skin tones and hair colors, though some humans were completely bald. Most humans were unremarkable in comparison to other alien races and lacked any sort of natural defense measures like armor or Psychokinesis. However, each human carried pure Furon DNA, since some humans were descendants from Furons who came to Earth eons ago.
Human Technology was terribly archaic and in-efficient when compared to Furon or Blisk Technology. However, Humans employed a much more vast array of resources, but carbon combustion and electricity were the most commonly seen. However, humans were able to develop nuclear power to compensate. Humans were new to space travel and their ships were quite slow. Despite those disadvantages, humans could still pose a major threat: their nuclear missiles were capable of destroying the Furon Mothership and most other Furon Structures and their armaments could easily disable a Furon's personal shields.
