Tarzan is a party member in Kingdom Hearts. He is a wild, almost animal-like man who has been raised by gorillas since birth. He speaks little English, conversing mostly in gorilla language which is a combination of grunts and hoots. Because of his long time in Deep Jungle, he has developed rather impressive acrobatic skills similar to the movements to a monkey, and he even can "surf" down tree branches and vines, as well as using vines to swing across great distances. He fights with a spear made from a sharp rock tied to a branch.
Tarzan first encounters Sora in his former treehouse home, being attacked by the leopard Sabor. Tarzan manages to chase off Sabor and becomes friends with Sora, albeit through a difficult conversation due to Tarzan's limited vocabulary. Sora asks for Tarzan's help to locate Riku and Kairi, although Tarzan doesn't really understand. He leads Sora through the jungle's depths to an encampment where Sora meets Tarzan's friend, Jane Porter, who is surprised to see Sora, and later Donald and Goofy. Clayton, a hunter whom Jane brought to the jungle, attempts yet again to persuade Tarzan to show them the location the gorillas. Tarzan, however, cannot do it as the leader of the gorillas, Kerchak, is distrustful of the humans. At this point, Clayton has his heart taken by the Heartless and he falls into darkness. Sabor attacks Sora and Tarzan again, but they kill him.
Jane and Terk are briefly kidnapped by Clayton, but are saved shortly after by the Keyblade bearer. Unfortunately, Clayton and his gang of Heartless have now captured all the gorillas to be shot. Sora and Tarzan intervene and the gorillas escape. Clayton and a large Heartless named Stealth Sneak fight Sora, Tarzan, Donald and Goofy, but they are defeated, and the Heartless crushes Clayton. Tarzan seems to be able to tell that Clayton is no longer human, and expresses his discovery immediately before the fight. Grateful for their rescue, the gorillas show Sora and the others the location of the world's Keyhole. Jane then figures out what Tarzan's continuous grunting means: Friends in the heart (the word heart is subtitled in punctuation symbols).
Tarzan's brown hair is styled in long dreadlocks. He wears almost no clothes. The only piece of clothing he wears is a tattered, brown loincloth around his waist. His eyes are a light green-blue in color and his muscular body is tanned from living in the jungle all his life.
Tarzan is a gregarious character, especially when is among his "family", the gorillas. He cares deeply about his friends. It also seems Tarzan can feel it when people hurt his friends, because he did not trust Clayton when he said he did not feel like harming the gorillas. Tarzan is almost always the first to rescue people when they are in danger: He rescued Sora from Sabor, and later, along with Sora, Donald and Goofy, he rescued Terk and Jane.
Tarzan is a heavily physical character that wields a spear with long reach and high strength. He only has one equipment slot and three item slots. He uses his spear in tandem with a variety of special techniques; however, he lacks the MP to support frequent use of his techniques.
His combat abilities are a mixture of offensive and defensive skills. Tarzan's special attacks allow him to use spear techniques, such as Raging Boar and Asp's Bite. His defense skills, Healing Herb and Wind Armor, convey the same effects as Cure and Aero. Tarzan also has a variety of support abilities, including Second Wind, Second Chance, Berserk, and Critical Plus.
In the film, Tarzan is a human infant who was taken in by the gorillas after his parents were marooned in a shipwreck and subsequently killed by Sabor. He grows up befriending the jungle's inhabitants and learning their ways, but often butts heads with his adopted father Kerchak. When Jane Porter, her father Professor Archimedes, and their guide Clayton set up camp near Tarzan's home, Tarzan eventually befriends them and learns English and basic manners and etiquette. However, Tarzan distrusts Clayton, and his fears are realized when Clayton begins to capture as many gorillas as possible. After Tarzan, Jane, and the Professor are rescued by Tarzan's jungle friends, Clayton chases them back into the jungle and battles them, only to fall to his demise. Kerchak sacrifices himself to protect his family, appointing Tarzan as his successor. Jane and the Professor stay behind in Africa to study the gorillas, with Tarzan and Jane living in his family treehouse.
In the film, he was voiced by Tony Goldwyn, who reprised the role in Kingdom Hearts.
