Gark

Gark was an Arunde. He wanted to hunt in the lower levels of the jungle against Sharna's wishes. He watched the First Doctor, Jospa and Ian Chesterton explore; thinking that they might want to destroy the Arunde, he wanted to attack them. He started to fearmonger. He tried rebel against the matriarch and get the rest of the Arunde to be on his side. Jospa got him to search for his controller in the TARDIS. Sharna later banished him from the tribe.
