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?
|—Connie- "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 magenta lens-less glasses (with rose-colored lenses until "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, green, 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 is introverted, curious and intelligent. Due to her parents' lifestyle, specifically her father's, Connie rarely stays in one place for long and has been unable to form lasting friendships, which left her frequently 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 fats). 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 awed 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. Due to Pearl's negative reinforcement she also began to display a reckless side, but this was quickly put out by Steven. It also highlights her strong feelings for Steven in her devotion to him in becoming a knight.
- Swordsmanship: As of Sworn to the Sword, Connie has become skilled in the art of sword-fighting with Pearl as her mentor. 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.
- Tag-team Combat: Connie is able to coordinate her swordplay perfectly with Steven's shield and barrier powers, such as fighting back-to-back to defend and attack simultaneously or jumping off of Steven's shield to add extra power to her lunges.

RelationshipsAn Indirect Kiss" and "Alone Together" (in the latter of which Steven and Connie accidently fuse, forming Stevonnie ) . 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 if absolutely necessary. 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 seeing Steven due to the huge risk she willingly submits to every time they hang out.
"Nightmare Hospital" explores Connie's relationship with her mother in more detail. Connie is prone to lying to her mother about her adventures with Steven, who is very strict with her, enforcing many rules on her that she never retracts for any reason. She remains untrusting of Connie when they and Steven are cornered by Gem fusion experiments at the hospital. However, after the ordeal, she agrees to be more accepting of Steven's influence in her life and much less micromanaging about Connie's life, although it is currently unknown how Mr. Maheswaran reacts to Steven's influence on Connie.
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", where she also convinced Pearl to teach her sword fighting by appearing very passionate about staying by Steven's side to fight with him, which clearly struck a chord with Pearl.
