I don't know what will happen in the future, but if something dangerous comes along, I don't want to be a burden, I want to help, I want to be there for Steven to fight by his side! The Earth is my home too, can't I help protect it?
|—Sworn to the Sword|
Connie is a young girl with brown skin and waist-length dark brown puffy hair. She has a prominent nose, thick eyebrows, and wears a pair of red lens-less glasses (after the events of "An Indirect Kiss"). She is slightly taller than Steven.
Connie is usually seen in a variety of different outfits and dresses. She usually wears light blue and white clothing. In the first intro, she is seen wearing a white and seafoam-green dress with her peach colored boots but with a sunhat and no socks. Her glasses also have the lenses still in. Her casual wear includes blue overalls with a green-striped white shirt; a green shirt and gray khaki shorts; a white shirt which has a golden sun on the chest area, with blue shorts and dark pink flats; a pink shirt with blue shorts, and her boots; a sleeveless sky-blue dress with a pale violet lace around her waist, and powder blue flats.
Connie has a bookworm-ish personality, generally being withdrawn and introverted, as well as curious and intelligent. Due to her parents' lifestyle, Connie rarely stays in one place for long and has been unable to form lasting friendships (until she met Steven), often feeling lonely. Her parents are very strict and don't allow her to participate in common childhood activities (such as eating donuts or anything with trans-fat). This has led her to flat-out lie about Steven's non-nuclear family, due to paranoia at how they may react. Despite her obedience to her parents, Connie is not above exploiting loopholes, such as not buying snacks at a theater and instead bringing them from Steven's home.
Connie has grown used to the strange dynamic of her friendship with Steven despite her initial uncertainty of it, as in "Marble Madness" when the Gems destroy one of Peridot's robots in front of her, she reacts passively and only comments that she loves hanging out at Steven's place. She can be a bit deadpan at times, such as when she jokes about cutting off Steven's hand in "Lion 2: The Movie" and in that same instance quickly understands that by poking/tickling Steven she could provoke a reaction from Rose's Secret Armory. Her hobbies appear to include tennis and reading, and she also plays the violin, as seen in "Fusion Cuisine".
"Sworn to the Sword" shows a more confident and aggressive side to her personality as she learns how to use a sword. It also highlights her strong feelings for Steven in her (misguided) devotion to him in becoming a knight.
- Fusion: First shown in "Alone Together", Connie is able to fuse with Steven to create Stevonnie. This is most likely because Steven is half-human.
- Swordsmanship: As of Sworn to the Sword, Connie has become very skilled in the art of sword-fighting. She was able to work in partnership with Steven and his shield. She can attack swiftly with light attacks or with power in heavy attacks.

Steven first saw Connie about a year prior to the start of the series during a parade. He saw her drop her bracelet, and decided to keep it in his freezer so he could return it the next time he saw her. She also remembered seeing him on his father's float, mentioning the soap bubbles in his hair. He becomes her first friend. Although Connie sometimes feels like her life is rather mundane compared to Steven's, they are currently good friends, and share a mutual crush on each other as seen in "An Indirect Kiss" and "Alone Together". Connie has demonstrated that she cares deeply for Steven, such as in "Full Disclosure" when she repeatedly called and visited him to make sure he was okay, even going as far as to say she wanted to "be a part of his universe", and since "Sworn to the Sword" Connie has shown interest in joining Steven in his adventures with the Gems, training with Pearl to defend him.
Connie is very loyal to her parents. While they tend to be strict, they want the best for her, and want her to be smart, orderly and healthy. She closely follows their orders, but does occasionally exploit loopholes or even lies to them to get away with something. In the episode "We Need to Talk", Connie reveals that her parents do not know of her adventures with Steven. This may be because of her fear that her parents will prevent her from hanging out with Steven due to the danger she gets put in.
Connie is on good terms with the Crystal Gems. In "Bubble Buddies", they were excited to meet her. Pearl says in "Full Disclosure" that she doesn't understand human relationships when she is looking for Steven.
Connie has not been shown to have any extended interaction with the Gems with the exception of Pearl, with whom she shares a mutually respectful mentor-student relationship since "Sworn to the Sword".

Northern Kalaripayattu is based on elegant and flexible movements, evasions, jumps and weapons training. Normally, Kalaripayattu can be started at the age of seven, when the body is not stiff and less vulnerable to damage. But it can be practiced at any age under the supervision of a well-experienced master, such as Pearl.

- It has been revealed by Ian Jones-Quartey that Connie's age may be revealed in an upcoming episode.
