Killoran

Biology
Killorans were sentient, canine humanoids who resemble a six or seven-foot-tall cross between a wolf and an ape. They had fur covering their bodies, and extremely strong teeth. Due to their tremendous strength, Killorans are much in demand as construction workers. (BFBS: The Doomsday Manuscript, The Stone's Lament)

Since the Killoran language cannot be spoken by humans, Killorans living or working among humans generally adopted a pseudonym. They tended to favour names drawn from Earth history, especially names of military leaders.

Kilorans and humans have similar reproduction techniques that allow for sexual interaction to take place. (BFBS: The Squire's Crystal)

History
Kilorans invaded the planet Világ, a planet populated by humans. (BFA: Arrangements for War)

A Gallifreyan legend maintains that Pandora, a long-ago [Lady President]] of Gallifrey, had a female Killoran bodyguard. (BFG: Lies).
