Kal
Kal was an outsider taken in by Za's tribe, the Tribe of Gum, circa 100,000 BC.
Biography
Early life
Kal was part of a tribe that died in the cold. He too would have died but came across the Tribe of Gum. Their leader, Za, chose not to kill him and permitted him to eat with them and share their caves.
Whilst Za spent his time attempting to make fire, Kal brought meat to feed the tribe. This led to Horg and the other old men of the tribe to begin favouring him and considering making him leader. Whilst Kal could not make fire, he claimed to have often seen men make fire where he was from. (TV: An Unearthly Child)
Bid for leadership and death
Kal saw his chance to become leader when he observed the First Doctor emerge from the TARDIS and produce fire by striking a match on a rock and breathing smoke through a pipe. Kal captured the Doctor and took him to the tribe, where he hoped to force the stranger to tell him the secret.
The old woman helped the Doctor and his companions escape the Cave of Skulls into the forest. Kal killed her in anger and blamed Za, but, when the strangers returned with Hur and an injured Za, the Doctor proved it was Kal who had killed her. The tribe drove him into the darkness.
Kal later sneaked back, seeking revenge on the strangers, and was confronted by Za. The two fought, during which Za killed him by smashing his head with a big stone. (TV: An Unearthly Child)
Personality
Kal was desperate to become leader of the Tribe of Gum and was willing to lie and murder to achieve his goal. He lied to Horg and the old men of the tribe to curry their favour and murdered the old woman to frame Za. (TV: An Unearthly Child)
Behind the scenes
Kal has the honour of being the first villain on Doctor Who. Though Kal himself does not appear until the second episode of An Unearthly Child, "The Cave of Skulls", his shadow appears falling over the landscape during the last few seconds of the first episode, also called "An Unearthly Child".
