Susan Strong (birth name: Kara; designation: Seeker XJ-7-7) is a recurring character in Adventure Time who first appears in the episode of the same name. Susan Strong lives underground with the members of the Hyooman tribe, whom she leads in an attack against the Candy Kingdom. At first, she cannot speak much English and is afraid of many things, but Finn and Jake teach her about the ways of Ooo.

Susan returns in the season three episode "Beautopia." She asks for Finn's help to reclaim the Hyoomans' old home, the underground city of Beautopia. Susan, Finn, and Jake use fire to fight off the Lub Glubs, scary monsters that take the form of pool floats, allowing the Hyooman tribe to return to their city. At the end of the episode, Susan allows Finn to feel under her hat, letting Finn know if she is human or not; however, Finn's reaction does not reveal the truth to the viewer.

However, three seasons later, In the episode "Dark Purple," Susan rips off her hat to reveal that she is indeed a human, but appears to have some sort of cybernetic implant on the left side of her head which means she is a cyborg.

It is revealed in the episode, "Preboot" that Susan's implant has something to do with Dr. Gross, and that until this point, was deactivated. When it becomes activated due to electricity in "Reboot," she speaks in a robotic-sounding voice and attempts to take Finn to the edge of the ocean, claiming he is her "objective." While in this state, she is able to absorb the blast from a Gumball Guardian and make herself larger. At the end of the episode, Finn destroys the cybernetic implant and Susan returns to her former self, becoming wholly human in the process.

In the Islands episode "Hide and Seek," it is revealed that Susan's birth name is Kara Strong and she grew up on one of the human islands outside of Ooo. Since she was a child, she was in school training to be a "seeker" who are people who are supposed to stop people from leaving the islands. She had a close relationship with Dr. Gross and had a friend named Frieda. Frieda wanted to leave the islands and explore the outside world. Kara told Dr. Gross about her. She was about to help Frieda leave, but Dr. Gross came by and activated her cybernetic implant and made her destroy Frieda's machine.

In "Helpers," it is revealed that after Martin and Finn disappeared from the island, Dr. Gross sent her most powerful seeker (Kara) to find them. However, she likely did not find them and it is unknown how she ended up in the underground and was most likely very traumatized and suffered amnesia because a flashback in "The Invitation" shows her crashing a ship in the ocean, likely from an encounter with the Guardian.

After regaining her ability to speak normal English and regaining some of her memory in "Min and Marty," Susan took Finn, Jake, and BMO to Founder's Island. They arrive at the beginning of "Helper" and after a period of time she sees her old friend Frieda from a distance. She catches up with her in "The Light Cloud" and apologized to her for destroying her plans to leave the island. Frieda told Susan that its okay and she's over her dreams of exploration. Susan tried to convince Frieda into being upset and she should not give up on her dreams of leaving the island but she had to bring her to Finn, who was giving a long speech in front of a crowd of the human citizens about how they have no freedom. After getting the approval of Minerva Campbell to leave the island Susan, along with Finn, Jake, BMO, Frieda, and Minerva, turn off the island's Guardian. After this Susan, along with Frieda, says goodbye to Finn and has plans to go to some far-away land. At the end of the episode, she decided that she liked the name Susan better.


Susan is a female human. She is a very large and muscular woman, towering over Finn and Jake. Her skin seems tanner than Finn's skin, and she has long blond hair, seen down her back, and green eyes. Part of her hair is shown to be shaved off around the implant on her head. She wears a ragged, short purple dress and a dark-grey hat made to look like the head and body of a cat with long whiskers and tail. It is later learned that this hat is part of a uniform that designates her as a 'Seeker.' True to her name, she is physically incredibly strong, being able to crush boulders and fight off monsters by herself. She doesn't appear to own shoes, so she is seen mostly walking barefoot. 

In the episode "Dark Purple," she wears torn, dark purple shorts and a tank top the same color as her dress.


Initially, Susan does not speak English like Finn and Jake, but instead speaks the Hyooman language.

Throughout the episode "Susan Strong," Finn and Jake teach Susan about objects in the surface world and their English names. By the time they visit the Candy Kingdom, Susan has a decent grasp on the English language and can form simple sentences. In "Beautopia," her English improves dramatically, and she is able to speak in clear, slow sentences. Some of her speech is still grammatically incorrect, however.

In the episode "Susan Strong," Susan receives her name when Finn misunderstands Susan's repeated attempts to say the word "sun." She clearly knows the English word "sun" and recognizes what it means. This fact coupled along with her rapid absorption of English indicates that she may have spoken English at one time in her life but forgotten it.

In "Hide and Seek," it was confirmed that she used to speak coherent English like other humans before speaking the Hyooman language. In "Min and Marty," she has regained the ability to speak coherent English. She also mentions how good it feels to use big words again.
