Warrior race

Warrior races were species dedicated to war and fighting. The Seventh Doctor explained that "Warrior races are ten a penny. Every civilization goes through a warlike phase - it's an outgrowth of the 'survival of the fittest' ethos. Most races either see the error of their ways, or else they wipe out either themselves or each other." (PROSE: First Frontier)

Temmosus of Skaro observed that his people, the Thals, had changed from a "once famous warrior race" to farmers in the centuries following the Neutronic war. (TV: "The Escape")

The Fourth Doctor described the Jagaroth of the distant past as "a vicious, callous, war-like race." (TV: ''City of Death

The Tzun never outgrew their warrior phase, and just became more intelligent and more dangerous, being among the most skilled warriors in history by 1957. (PROSE: First Frontier)

The Seedle Warriors, who were employed by Helron to track down the early Renegade Time Lord Azmael, were referred to by the Scrolls of Gallifrey as a "warrior race". (PROSE: The Legacy of Gallifrey, The Twin Dilemma)

The Eleventh Doctor identified the Daleks as the "most advanced warrior race". (TV: Asylum of the Daleks) He also described the Sontarans as a clone warrior race. (TV: The Snowmen) The Twelfth Doctor identified the Mire as "one of the deadliest warrior races in the entire galaxy." (TV: The Girl Who Died)

The prophecy of the Hybrid spoke of the Hybrid as being of "two warrior races" forced together. Davros believed these two races were the Daleks and the Time Lords. (TV: The Witch's Familiar) When arguing that Me could be the Hybrid, the Doctor noted that Humans and the Mire could also be considered warrior races. Me shot back that by the same logic, if humans counted as a warrior race, the Hybrid could be half-Time Lord half-human — bringing up the possibilities of the Doctor themself and of the "dangerous combination" formed by the Doctor and Clara Oswald, which could metaphorically be compared to a "hybrid". (TV: Hell Bent)
