Clayton (voiced by Brain Blessed) is the main antagonist of Tarzan. Clayton is a British hunter who was obsessed with hunting gorillas and selling them on the black market. Clayton acted as a guide to Jane and Dr. Porter and attempted to use Tarzan as a means of finding the gorillas. He and his men soon captured Tarzan, Jane, Dr. Porter, Jaden and his team and started to capture the gorillas. But Tarzan and the others escaped and managed to stop Clayton's thugs. Clayton shot Kerchak and had a fight with Tarzan. Clayton met his end when he was entangled in vines and he mindlessly hacks the vines with his machete. He failed to notice that one vine was under his neck, and he cut the only vine he held onto and fell and was hanged to death.
