|~ Kala to Tarzan|
She is voiced by Glenn Close.
Kala is calm, gentle, kind, loving, and beautiful. She loves her son Tarzan unconditionally, although she said that she knew Tarzan wouldn't replace her firstborn son who was killed by the leopard Sabor. Although she is usually a gentle person, Kala is capable of aggression when necessary and is also very brave, fighting against the deadly leopard Sabor in order to protect baby Tarzan. Kala often disagreed with her husband Kerchak but despite this they did love each other and Kala was sad when Kerchak died.
Kala is first seen with Kerchak and their young son. However one night, the young gorilla chases a bug and runs into a leopard called Sabor, who pursues the youngster. Kala and Kerchak hear the noise and rush to help their son, only to arrive too late and watch on in horror as their son is attacked and killed by Sabor. Kala weeps over her son's death whilst being comforted by an equally devastated Kerchak.
Sometime later, Kerchak (presumably to prevent anymore deaths) leads the gorillas to a new home. Kala hears crying and leaves the group and follows the noise. She comes to a treehouse and finds a human baby, whose parents were killed by Sabor. Just then, Sabor appears and attacks Kala. Luckily, Kala is able to escape her and takes the baby back to the group. Kala shows the baby to the other gorillas (including her niece Terk). Kerchak arrives and tells Kala to take the baby back as he cannot replace their son. However Kala is able to get Kerchak to change his mind and let her keep him after she reveals that Sabor killed the baby's parents. Kala then names the baby Tarzan.
A few later, Tarzan, now a young boy, unintentionally causes an elephant stampede whilst trying to get an elephant hair for Terk and is mistaken for a piranha by a young calf named Tantor (who Tarzan later befriends). After being scolded by Kerchak for what had happened, Kala comes to the boy's defence and is berated by her husband for doing so, believing that Tarzan would not learn from his mistakes or learn to be a gorilla, to which Kala replies that Kerchak never gives Tarzan a chance to prove himself. Kerchak angrily declares that Tarzan will never be one of them. After Tarzan runs off in sadness, Kala follows him and comforts him and encourages him to improve himself and show Kerchak that he can be as good as any ape.
Years later, Tarzan grows into a young adult and battles and kills Sabor, to the proudness of Kala and the other gorillas.
