Steven Universe Mini Plush from Steven Universe. A half-human half-Gem 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 an escort of the Crystal Gems into an equal amongst their ranks thanks to his good-hearted nature and resourcefulness. Though he is a part of a monumental legacy Steven is devoted to fulfilling his destiny as protector of humanity just like his mother was before him.
