- "I'm not trying to be some kind of martyr, or say that I'm always a screwup. I'm not. In my world, making hard choices is part of the deal. Sometimes I'm right, sometimes I'm wrong. Sometimes I just can't tell, even when the mission is over and we've all come out alive, at least."
Cassie is a founding member of the Animorphs, an author and a state diplomat and official. She was instrumental in helping the Animorphs acquire their various animal morphs and played a key role in the Andalite-Yeerk War, being responsible for handing the morphing cube over to the Yeerks. Following the war, she became an author and by the age of nineteen, worked alongside the President of the United States.
Cassie's family owns a farm that has been in the family since the Civil War, and has been remodeled into the Wildlife Rehabilitation Clinic; a sort of animal hospital for livestock and wild animals. Cassie helps her dad frequently take care of the wild animals staying there.
Becoming an Animorph
One night, Cassie, along with her best friend Rachel, Rachel’s cousin Jake, his best friend Marco, and a kid Jake saved earlier that week named Tobias decided to take a shortcut home from the mall through a construction site.
There, the five of them find a dying alien named Elfangor-Sirinial-Shamtul and learn all about the Andalite-Yeerk War, including that the Yeerks have already infested a large percentage of humans. To combat the Yeerks, Elfangor gives Cassie and the rest of the teenagers the morphing ability.
Befriending the Enemy
During an attack on a Sharing meeting, right after Jake orders his team to retreat, Cassie tears the throat out of a Hork-Bajir and kills him. Ridden with guilt, Cassie decides she has had enough of fighting and killing and quits the team.
Later, she meets Aftran 942, who is the Yeerk in the body of Karen, a young girl who does not want to be infested. After Cassie and Aftran discuss the ethics of Yeerks taking hosts, Cassie and Aftran make a deal that if Cassie will agree to become a nothlit in a caterpillar's body, then Aftran will agree to leave Karen's body and never infest anyone again. Cassie stays in caterpillar morph for more than two hours and compelled by Cassie’s compassion Aftran keeps her promise and releases Karen.
A few days later, Cassie, as a caterpillar transforms into a butterfly, which resets the morphing clock and allows her to demorph.
Pacifist in a War
Over the course of the series, Cassie struggled with retaining her pacifist nature and violating other creatures’ personal rights. Acting as the moral compass of the group, Cassie was the one who argued against acquiring other humans’ DNA without their permission. On one occasion, she was considering whether or not a buffalo who acquired the morphing technology was sentient or not.
Realizing they are outnumbered, the Animorphs decided to use the Escafil Device to create new Animorphs, with Cassie offering to recruit handicapped children since there would not be a risk of the recruits being Controllers, due to the Yeerks deeming them as defective.
After the Yeerks find out the Animorphs’ intention, a fight ensues and Jake chases Tom’s Yeerk into the forest. As Tom flees with the morphing cube, Jake stalks him in tiger morph, preparing to kill him and retrieve the cube. Cassie, believing that Tom should escape with the cube for reasons she is unsure of, coupled with a desire to save Jake from crossing a personal line by killing his brother, attacked Jake, allowing Tom to flee with the cube.
Having romantic feelings throughout the series, Jake proposed to Cassie before the final battle against the Yeerks, although she suggests that he ask her again a year after the war ends, unsure of whether Jake can live a normal life post-war, should they survive.
- "We Animorphs and the newly minted Prince Aximili, with our prisoner, landed Ax's official liaison ship, a sleek Fast-Courier, right in the middle of the Mall in Washington. Not a mall, the Mall, a sort of open green space with the Capitol Building at one end, the Smithsonian Institution and various government buildings on both sides, and the obelisk of the Washington Monument at the far end. We called ahead, not wanting to terrify anyone. There were roughly a thousand cops and twice that many newspeople waiting for us. It was, as Marco said, a "shiver-my-spine moment." A sea of microphones and video cameras and flashbulbs. Ax and Jake, and to a lesser extent Marco and I, gave a sort of brief explanation of what had been happening, and where things stood now. Needless to say, it was kind of a big news day."
- "Cassie was Undersecretary of the Interior for Resident Aliens. It paid less than I spend on corn chips, but hey, Cassie was seventeen, like me, and she was meeting with the President and spending most of her time with the free Hork-Bajir. [...] Anyway, Cassie was a government poo-bah, always racing around here and there in government jets and helicopters, making sure Toby and her people were good and just generally saving the world. Also taking college courses at night because she still wants to be a veterinarian like her mom and dad. That's Cassie for you: Save the rain forest, save some cow with a hernia — the girl just does not get the whole celebrity thing. I mean Wal-Mart practically begged her on hands and knees to take a million dollars to do ads for their jeans, and she said she didn't have time because there was some controversy over an access road into some forest somewhere."
At only seventeen years old, Cassie became an important activist, dealing with environmental issues and taking care of the free Hork-Bajir. She was saving the world by day and taking veterinary courses by night so that she would become a veterinarian like her parents.
- "I wasn't just Cassie the Animorph anymore. I had been moved out of the Interior Department when the new President was elected. She had appointed me instead to the new position of Special Assistant to the President for Resident Aliens. I was nineteen and I was in the President's sub-cabinet. [...] I was Cassie the Animorph, always would be. I was in history books, after all. But I had a different life to lead now. I was going forward."
- "An entire human race of Rachels — angry, merciless, aggressive, and equipped with Yeerk and Andalite technology. It was a terrifying specter. But perhaps... perhaps I had been wrong. Perhaps the real menace lay at the other end of the continuum — represented by Cassie. Humans who were softer. Kinder. Well-meaning. And, ironically, infinitely more dangerous."
Relationships with the other Animorphs
- "Jake and I are closer than just friends. We care a lot about each other. Or at least we used to. Now everything was changing. Everybody was changing. I didn't know who was who anymore. Sometimes, I didn't even know what I felt."

Jake and Cassie have crushes on each other right from the beginning of the series, and a romance slowly develops between them. They share their first kiss in The Attack, and in later books they both acknowledge the love they have for each other in their narratives, though they have not stated in outright. Towards the end of the war, their relationship deteriorates and Jake loses trust in Cassie after she allows the Yeerks to gain the power to morph.
- "She'd been my best friend forever. Teased me about my clothes as I teased her about her obsessive shopping. How long ago had that been? A hundred years? She'd wanted to be a gymnast but thought she was probably too tall ever to be really good. And of course all that was in the past, too. She had this way of seeming untouched by what went on around her. Unaffected. Above. She was a person who could walk through a car wash and come out dry. She could move through a mosh pit and never be jostled. She could wear a white dress to dig in the mud and somehow never get a spot on her. But the war had touched her. She'd changed, and she'd known she was changing. The war had revealed a hidden part of her soul. She alone, of all of us, she alone liked it. Loved it, even. She had enjoyed the fight. Sometimes I imagined her as a Viking. Or as a knight on a quest. That's what she was: a joyful warrior."

Cassie and Rachel are best friends, despite being complete opposites. Their friendship becomes strained in later books, as Rachel becomes increasingly drawn to her warrior side and becomes impatient with Cassie's strong ethical convictions.
- "Tobias is a nothlit. Someone who stayed in morph beyond the two-hour time limit and got trapped in that morph. None of us are one hundred percent sure it was an accident. Sometimes we think Tobias is happier as a hawk. That he let himself be trapped, on purpose. But none of us has come right out and asked him. At least, I haven't. And none of us has asked if given the same situation he'd do it again. Assuming Tobias chose his fate and wasn't just a victim of a really bad circumstance."

While they don't interact as often, they are still good friends. He is the closest in attitude to her, and they generally side together on group votes. Cassie's house is physically close to Tobias' territory. In The Beginning it's mentioned that while Tobias has stopped talking to Jake and Marco (after Rachel's death), he still does keep in touch with Cassie.
- "I felt a wave of affection for Marco. We had never been the closest of the Animorphs — our connection went through Jake, it wasn't direct. But here we were, in some way the only two real survivors. We had even prospered. Each of us was far better off by most measures than we'd have been without the war."
This section requires expansion
Although they are generally on good terms, Cassie and Marco are not close and don't spend much time together. There is some personality conflict between them, as Cassie's morality is diametrically opposed to Marco's ruthlessness. However, at the end Cassie notes that she and Marco are really the only "true survivors" of the war and together they agree to try and break Jake of his depression.
- "I didn't want to say the words. I didn't want to. But Ax was more than a friend. How many times had he risked his life to save mine? I couldn't count the number of times I'd been down and only his flashing tail had brought me out alive."

- She is more talented at morphing than the others. Ax notes that Cassie could easily become a professional estreen, one who morphs as a form of art, due to her inherent skills.
- She has the unconscious ability to unravel any alternate/parallel universe/timeline.
- All of the models for the Animorphs featured on the front and inside cover had been changed since the series began, mostly because the original kids had grown up and moved away to college (since book 41). Only Cassie's model (Biko) remained close enough to still model for Animorphs. And of course Ax, who is actually just a cardboard cutout.
- In keeping with her non-violent nature, Cassie is the only Animorph who lacks a unique battle morph; she typically assumes a wolf form when required to fight, which most of the team acquired while investigating Yeerk activity in the mountains.
- In 1999 three different Animorphs toys of Cassie were made.
- Cassie is the only original Animorph not to accompany the group on the mission to rescue Ax at the end of the series, and possibly the sole surviving original Animorph after the series' end.
- In the TV series, it's Cassie who's allergic to crocodile DNA, not Rachel. Also, unlike Rachel whom would transform into random animal several times when the allergic symptoms shows up, Cassie only suffer partial transformation on random parts of her body instead.
