Stevonnie

Stevonnie is taller than Amethyst and Pearl but is a few inches shorter than Garnet. They have an average/athletic build consisting of Connie's slim figure with Steven's chubby and stocky features and a medium complexion between both of their components. However, unlike Steven and Connie who sport dark brown hair, Stevonnie has curly dark purple hair that reaches to their thighs. Stevonnie also had a deep tanned skin. Because Steven nor Connie's shoes fit them, they are usually barefooted. Stevonnie can also grow facial hair, a trait acquired from Steven. Steven and Connie's "ages combine" when they form Stevonnie and that Stevonnie can grow more facial hair than Steven due to being biologically older. Stevonnie is considered to be very physically attractive by both male and female citizens of Beach City as they seem to be in awe of their appearance. Due to being a fusion of a boy and a girl, Stevonnie is intersex and uses They/Them pronouns.

Stevonnie's personality is unique. As a fusion, they do not have a single, distinct personality, but instead, have a blend of both Connie's and Steven's minds, and they frequently alternate in their control of Stevonnie's behavior and thoughts. They carry the free spirit, friendliness, and fun-loving attitude of Steven and the courtesy, awkwardness, and intelligence of Connie. During their fight with Jasper, Stevonnie shows courage and determination to protect Amethyst from Jasper and to defeat her, inherited from both Connie and Steven.

Much like Garnet, Stevonnie is a highly stable fusion, reflecting the strong synergy between Steven and Connie when they are unfused.

When under pressure, Connie's and Steven's personalities may become more distinct, as when Stevonnie unintentionally became the center of attention at the rave party, they suddenly became nervous and had a panic attack, something that can be traced back to Connie rather than Steven. During the first half of the Beach City Drift race, Stevonnie was shown to be rather obsessive about getting back at Kevin. This trait could be inherited from Steven, because of how much anger he had towards Kevin. However, near the end, Stevonnie seems to be more carefree, simply ignoring Kevin's remarks and attempts to get their attention. It also shows that Stevonnie possesses Connie's practicality along with Steven's sentimentalism as they argue over eating a beaked alien.

Abilities:

Stevonnie, like all fusions, possesses an extreme amount of superhuman strength and agility. Despite being more human than Gem, Stevonnie is much stronger than Steven by himself, most likely stemming from Connie's athleticism combined with Steven's superhuman abilities. Stevonnie is strong enough to fight equally with a powerful Quartz warrior like Jasper or numerous opponents like Holo-Pearls. They appear to be able to utilize all standard Gem abilities, including weapon summoning and possibly fusion.

Shield Proficiency: Due to possessing Rose Quartz/Steven's gemstone, Stevonnie can summon Rose's shield. With their enhanced strength as a fusion, they can withstand a direct strike from Jasper's crash helmet and absorb the potential knock-back. Like Steven, Stevonnie can use the shield offensively by throwing it.

Dual-wielding: Like Steven, Stevonnie can summon two shields at the same time.

Sword & Shield: As the duo, Stevonnie is shown to wield Rose's sword proficiently when used in conjunction with their shield for fighting both offensively and defensively.

Swordsmanship: Stevonnie is skilled in the art of sword-fighting, an ability passed on from Connie. Like Connie, Stevonnie is ambidextrous.

Driving: Stevonnie drove Greg's new car, the Dondai Supremo, with remarkable skill despite the lack of practice or experience before the race. They also know how to pilot Lars' ship, the Star Skipper, due to its resemblance to a car.

Immense Strength: Stevonnie is shown to be extremely strong, enough to knock the much larger Jasper back a considerable distance and drive her through the monster she was riding with enough force to poof the latter with one slash. It is implied by the "Ring the Bell" machine that Sardonyx used to test Smoky Quartz's strength, that Stevonnie's strength is rated (presumably by Sardonyx) as being greater than Pearl's but lower than Garnet's.

Enhanced Agility: Stevonnie is shown to be graceful and agile, as shown when they are running and when they are dancing, which requires nimbleness and agility. As an extension to this, Stevonnie is also an amazing skater. They're able to jump over Bismuth while high-fiving her and almost jump up to the ceiling before landing in a split.

Empathic Telepathy: Like Steven, Stevonnie has an empathic connection to other lifeforms and can communicate with Gems and humans through their dreams.

Speed of Descent Regulation: While fighting Jasper, Stevonnie remains in the air long enough to throw their shield at Jasper and prepare themself to use Rose's sword. They are shown to gain better control over this ability during their fusion training.

Flutter Kick: Stevonnie can lower themself down slowly by moving their legs rapidly forward and backward.
