Clayton (full name "John Clayton") is the main antagonist of Disney's 1999 film Tarzan. He was shown as a minor antagonist in the Deep Jungle in Kingdom Hearts.
He looks like many classic Disney villains, hungry for money and power. But what makes him stand out from the crowd is his harshness.
Like Cruella De Vil before him, Clayton's cruel treatment of animals (in this case, the apes), and Tarzan himself, makes him a chillingly cold villain so different from the run-of-the-mill animated bad guy. His character is also a home-hitting statement on poachers. Clayton is voiced by Brian Blessed.
Clayton puts on the facade of a calm gentleman, but in truth, he lacks self-control and is violent, ruthless, and selfish. His lack of self-control is what leads to his downfall. He also believes that all animals are nothing more than savage beasts which lack the capacity for any emotion whatsoever.
He is a very intelligent tracker and skilled hunter, and at the beginning of the first film, he does seem concerned about the well-being of the Porters (Archimedes and his daughter Jane).
