Diamonds

Your name is Steven Universe. Your mother was Pink Diamond, who sacrificed her life to bring you into being. And your father was an ordinary human. You grew up with Pink Diamond's former minions, as it was now their duty to look after you, now that you were half-human, not just a Diamond.

Initially, the other Diamonds thought Pink Diamond had been split and that she was dead, but when they learned she'd created you, they thought you were the new Pink Diamond, just in a different form. You never thought that way; you always thought you were you, but the Diamonds didn't care. They loved Pink Diamond so much, they wanted to take you back "home." Eventually, Blue and Yellow Diamond came to Earth and picked you up, bringing you back to Homeworld. When you arrived in Homeworld, since you were half-human, they placed special earrings on you, the same ones everyone in the Diamond Zoo wore. From these earrings, you could hear a voice telling you what to do, or simply giving instructions from the Diamonds, but you weren't living in the human zoo itself. You were assigned the Pink Diamond's former room, where you were now to live. This room was no ordinary one: the walls, floor, and ceiling were inhabited by tiny living stones that could build and create any furniture you wished. There was also a balcony, and the entire room was decorated in pink tones.

You didn't want to live there, you tried to escape, but the Earrings electrocuted you for every attempt. The Earrings electrocuted you even when one of the Diamonds simply didn't like your behavior, most often it was the White Diamond who disliked it.

Two years have passed since they brought you to the Homeworld, you have already become completely different, because you were literally trained by the Diamonds.
