Clayton

Clayton is a villain from the Kingdom Hearts series, originally from the 1999 Disney animated feature "Tarzan." He is voiced by Brian Blessed. Clayton was the only character who could control Heartless creatures, but was not part of Maleficent's Hellfire Club.

History
Clayton wields a double-barrel shotgun, a weapon he uses to hunt all manner of creatures in the jungle. He joins Jane Porter and her father on an expedition to the jungle to "study" gorillas, but he secretly wishes to sell them to the zoos in England. He has little patience for Tarzan, as he refuses to reveal the location of the gorillas.

Kingdom Hearts
Clayton finds Donald and Goofy in a bamboo thicket after they land in Deep Jungle. He questions Tarzan about the gorillas' nesting grounds, secretly desiring to hunt them down. Eventually Tarzan agrees to take him to the nesting grounds, but on their way there, Clayton attempts to shoot Terk, a young gorilla and Tarzan's friend. He is stopped by Sora, Donald, Goofy and Tarzan, and is forbidden by the furious Jane from approaching the gorillas. His anger and determination to hunt the gorillas lures the Heartless to him, and the darkness in his heart takes him over. He kidnaps 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, finding that he has lost his heart. Sora and company do battle with him and his Heartless. Although he proves to be proficient at using a shotgun at long range and even close range, swinging it like a club, Clayton and his Heartless are easily defeated. Clayton, outnumbered, summons a Heartless called the Stealth Sneak, mounting it and starting a boss battle. When Clayton is thrown from his steed, Sora defeats him. Afterward, the Stealth Sneak falls and ultimately crushes Clayton to death; his body disappears with the Heartless.
