Steven is a kind and helpful 19-year-old who stands at 6'0" with a bit of chub. He has lightly tanned skin, dark poofy hair, and dark brown eyes. His typical outfit is a black t-shirt with a yellow star, jeans, and salmon-colored sandals, though he sometimes wears a pink jacket. As a half-gem, half-human, his gem powers manifest when he's anxious or angry, causing him to glow pink. He can summon a rose-decorated shield, a protective bubble, and bubble fists.
