Clayton
Clayton is an English hunter who specifies in gorillas. He is from Disney's Tarzan. He appears on the World of Deep Jungle in Kingdom Hearts as an enemy. Clayton is voiced by Brian Blessed in both the movie and the game. Clayton is the only boss that is human and uses the Heartless that is not in league with Maleficent in Kingdom Hearts (game).
History
Clayton wields a shot-gun, a weapon he uses to hunt all manner of creatures in the jungle. He joins Jane Porter an an expedition to the jungle to 'study' gorillas, but he wishes to kill and sell them. He has little patience for Tarzan, as he refuses to reveal the location of the gorillas.
Kingdom Hearts
Clayton is the same as in the movie, his obssession with hunting all the greater. He finds Donald and Goofy after they land in Deep Jungle. He questions Tarzan about the gorillas and remarks that he really wants to hunt the gorillas. Jane eventually fires him after he attempts to shoot Terk, a small gorilla. His anger and determination to hunt the gorillas lures the Heartless to him, and the darkness takes him over. He captures Jane and Terk and imprisons them in the jungle. Then, he hunts out the location of the gorillas with the help of the Heartless. Just as he is about to kill them, Sora, Donald, Goofy and Tarzan arrive. Tarzan says that Clayton has lost his Heart due to using the Heartless. Clayton, out numbered, summons a Heartless called the Stealth Sneak. He mounts it and a boss battle ensues. When Clayton is thrown from his steed, Sora defeats him. In a cut-scene, the Stealth Sneak falls and crushes him.
