Steven Universe

Steven Quartz Universe is the titular main protagonist of the show of the same name. He is the son of Greg Universe and Rose Quartz, and the first and only member of human descent and hybrid nature of the Crystal Gems.

A human-Gem hybrid as a result of his parentage, Steven is an extraordinarily unique being with innate powers beyond that of both normal humans and Gems. While only a child, Steven has steadily grown from a tag-along to the Crystal Gems into an equal among their ranks thanks to his kind-hearted nature and resourcefulness. Though he is part of a monumental legacy, Steven is devoted to fulfilling his destiny as protector of humanity, just as his mother was before him.

Personality
Steven is an optimistic, friendly, outgoing, soft-hearted and carefree boy with a happy-go-lucky attitude that is appreciated by many of the citizens of Beach City in one way or another. He is musically inclined, a trait he inherits from his father, with a propensity for breaking out into song and occasionally playing on his ukulele. Steven is also very compassionate, something which Pearl notes he inherits from his mother, and he treasures his friends and family. He is friendly toward almost everyone he meets (even to his detriment), rarely holds grudges, and is very non-discriminatory, never treating anyone with prejudice, even his enemies. No matter the situation, Steven will always go out of his way to support his loved ones, even if it means putting his life on the line, and he will avoid resorting to violence if possible. He would much rather make a compromise and choose to reason than fighting back.

Steven looks up to his caretakers — Garnet, Amethyst, and Pearl — and considers them family. He wants to be a great hero just like them, and he is eager to go on adventures with the trio, both to prove his worth and to have fun exploring strange lands. Despite his under-developed magical power and lack of experience, he has proven himself to have much heroic potential through his resourcefulness, optimism, and confidence.

Appearance
According to Pearl and Vidalia, Steven takes after both his parents, Rose and Greg, respectively. He is relatively short with a thick, stocky build. He has curly black hair and full black irises. He wears a pink T-shirt with a gold star in the center of it. He also wears cuffed blue jeans and salmon-pink flip-flop sandals. His gemstone, a rose quartz, which he inherited from his mother, is where his navel should be.
