Terk loves the spotlight, and she is perfect "big sister" material because she's Tarzan's closest friend—protective, concerned, and absolutely convinced that Tarzan can't survive without her. Terk loves telling Tarzan what to do—that is, until Tarzan's physical strength proves he can hold her in a headlock instead. Even though Terk is a bit bossy at times, Tarzan knows it's because Terk cares, though she will never say so willingly. She is also the best friend of Tantor, who's neurotic persona often frustrates the ape to no end, though she truly values him as a friend and often takes advantage of him, selfishly.
In the movie, Terk is one of the young gorillas in Tarzan's Ape Family and she is the first to spot Kala coming back with Tarzan. When Terk first sees Tarzan she calls him creepy looking, to which her mother scolds at her for saying and Terk asks Kala what Tarzan is and Kala tells her that he's a baby and puts Tarzan in Terk's arms to which Tarzan starts playing with Terk and when Terk asks where Tarzan's mother is, Kala simply says she will be his mother now. Terk hands Tarzan back to Kala and tells Kerchak, the Leader, that Kala's going to be the baby's new mother. After Kerchak allows Kala to keep Tarzan, Terk asks Kala what she's going to call him, and Kala says that she's going to call him Tarzan. After that, Terk's mother picks her up and tells her that it's way past her nest time. Just before she went to sleep, Terk slid off her mother's belly, picked a leaf for a blanket and climbed back on her belly. When Tarzan grows into a little boy, he accidently runs into Kerchak, but Terk manages to help Tarzan by acting that she was looking for him, and takes him away from Kerchak.
Terk then orders Tarzan to stay away from Kerchak and then runs off to join some ape boys to which Tarzan asks Terk if he can come to which Terk says that Tarzan could come if he could keep up but he can't keep up. Terk then runs off to join the Ape Boys but soon Tarzan appears telling the ape boys that Terk said that he could come if he could keep up to which the ape boys complain that Tarzan is there and Terk takes aside and tells him that in order to convince the ape boys that he's cool enough to hang out with them he needs to go and get an elephant hair off an elephant's tail which is pretty dangerous and she tells Tarzan to go home but when Terk turns her head around Tarzan jumps into the water and swims towards the elephants to which the Ape Boys tell Terk that if Tarzan lives she should bring him around more often and leave to watch Tarzan get an elephant hair.
While trying to acquire the elephant hair, Tarzan is seen by the elephants and mistakenly assumed to be a piranha, causing the elephants to stampede in panic. The Ape boys are able to outrun the elephant herd, but Terk is caught on a vine and is swung up onto a nearby branch, allowing the elephants to pass safely beneath her. She then returns for the unconscious Tarzan, pleading with him not to die as she drags him from the water. After regaining consciousness, Tarzan accepts responsibility for causing the stampede and is scolded by Kerchak, who openly proclaims that Tarzan will never be one of the family. Tarzan then resolves to become "the best ape ever," an endeavor which Terk assists him in.
For a while Terk is clearly superior, but over time Tarzan becomes stronger and more athletic (the only character observed to be able to swing from vines), he also displays a higher degree of intelligence and ingenuity than the other Gorillas. Years later when Terk is a mid-sized adult gorilla, Tarzan, Terk, and Tantor are talking when Sabor the Leopard appears and attacks the gorilla family but Tarzan manages to fight the leopard to which Terk and the other gorillas cheer him on. After defeating Sabor, Terk and the other gorillas cheer for Tarzan and Terk tells him not to make that into a habit because there are other ways to get attention. Then they hear gunshots in the distance and Terk along with Tantor follow the rest of the gorillas as they move deeper into the jungle while Tarzan sneaks off to find out what that sound is. Later on Terk, Tantor and some of the other ape boys are out looking for Tarzan when they come across the humans' camp to which Tantor freaks out at the humans' stuff, but Terk replies, "These things aren't alive." Deeply curious, Terk, Tantor, and the ape boys use the humans' stuff to make up their own music (Trashin' the Camp song).Then, Tarzan appears with one of the humans named Jane Porter and begins to play with Terk but then Terk stops when she sees Jane. However, Tarzan gestures to her in Gorilla Language, saying that it's safe. As Jane is about to pet Terk, Kerchak, Kala, and the other Gorillas appear and order Terk, Tarzan, and Tantor back to their nest as they hear Jane's father Professor Archimedes Q. Porter and their guide Clayton coming. At their nests Terk listens as Kerchak orders the gorillas not to have anything to do with the humans much to Tarzan's dismay.
Wanting to learn more about the humans (Strangers Like Me song), Tarzan secretly sneaks back to the humans' camp to which Terk and Kala begin to worry. One day Tarzan asks Terk if she and Tantor can distract Kerchak while he shows the humans the gorillas to which at first Terk rejects but when Tarzan begs her she does to which she dresses up in Jane's dress and Tantor makes a puppet of Jane's father and manage to distract Kerchak while Tarzan shows the humans the gorillas. During the distraction Terk and Tantor accidentally lead Kerchak back to the gorillas' nests where Kerchak tries to scare off the humans but Tarzan manages to hold him off while the humans escape. Terk watches sadly as Kerchak scowls at Tarzan for betraying the family.
The next day Tarzan dresses in his biological father's clothes and decides to return to England with Jane, Porter, and Clayton to which Terk and Tantor try to catch him before he leaves and say good-bye but they're too late and sadly return to the Jungle. Then they hear Tarzan's cries from the ship to which Terk at first rejects to help but Tantor grabs her telling her that he's tired of her not wanting to help and they rush off to save Tarzan, Jane, and Porter who have been imprisoned in the ship's brig by Clayton and his men. After Tantor breaks into the brig Tarzan jumps out and Terk hugs him but Tantor pulls her aside telling her that sometimes she embarrasses him.
Then Terk, Jane, and Porter jump on Tantor's back and rush off to save the gorillas. After defeating Clayton and his men and rescuing the gorillas Terk watches sadly as Kerchak(who got shot by Clayton) accepts Tarzan as his son and tells him to lead the family and then dies to which Tarzan leads Terk and the other gorillas away to find a new nesting spot. The next day Terk watches happily as Jane and Porter decide to stay with Tarzan and are accepted into the Gorilla Family. In the end Terk is seen swinging in the tree vines but loses her balance and falls off-screen.
In the animated sequel, Terk and Tantor join Jane in finding the perfect, one-year anniversary gift for Tarzan. As they do so, they reminisce of moments they've shared together in the jungle during the time period. Even so, their goal to find the perfect gift was futile, and they return to the treehouse to find Tarzan has thrown his own surprise party in honor of the occasion.
Terk appeared as a kid to find Tarzan with Tantor to defeat the horrible monster.
In the TV series, Terk is now voiced by April Winchell. She is a major character, appearing in most episodes, and is often the comic relief whilst the others often take more dramatic roles such as Tarzan, and even Tantor at times. She serves as the loud, humorous, big sister figure to both Tarzan and Jane, tagging along on most of the adventures, and often getting herself into comically painful situations in doing so.
She can sometimes be the cause of trouble, such as in "Tarzan and the Giant Beetles", where she accidentally spills a special potion created by the professor on a group of beetles, turning them into giant beasts. In "Tarzan and the Rift", Tantor's girlfriend finds Terk to be obnoxious and forces him to choose between the ape or herself. In "Tarzan and the Beast From Below", she finds herself in situations rendering her as phobic as Tantor upon witnessing a living velociraptor.
Terk has a minor role in the game. She lives in Deep Jungle. Terk is frightened upon coming face-to-face with Donald Duck. Terk drops a Gummi Block which is picked up by Donald. Terk later flees from the Heartless and runs into Jane. Terk helps save her from the Heartless. When Clayton imprisons Jane in the treetops, Terk is by her side. Terk is almost shot by Clayton while she is playing in the Tree House (Clayton defended himself by saying that he was aiming at a snake that slithered by).
Unlike in the film, the gorillas don't speak, and Terk's only spoken line is a shocked yell at Donald.
Terk is rarely spotted at the parks but she can be found by The Camp Minnie Mickey entrance, by the entrance of Animal Kingdom with other characters such as Flik and Brer Rabbit and during Mickey's Not-So-Scary Halloween Party. At WDW Magic Kingdom, she might be found with Tarzan and Jane in Adventureland.
- In the original book series, Terk was a male (and his name was short for "Terkoz"), and he was not a sympathetic character.
- Originally, Terk was going to be a male like in the books, but the reason this was changed was because when male actors auditioned for the role, none of them worked, when Rosie O'Donnel auditioned, it worked out and she got the role.
- Some audiences of the film mistakened Terk for a male.
- Rosie O'Donnel voiced both the younger and older version of Terk, making her one of the few actors to voice both the younger and older versions of the same character.
- In the musical, like in the books, Terk is portrayed as a male (originally portrayed by Chester Gregory) and he is a tenor.
