Spinel has pink skin, magenta eyes, a small pointy nose, and magenta hair styled into two spiky pigtails. She has three black lines under both of her eyes, reminiscent of running mascara. She wears a plum top, puffy pointed hot pink sleeves, puffy rose shorts, hot pink wrist-length gloves, white stockings, and rose knee-high pointy boots. Due to her abandonment, Spinel is unhinged, prone to spontaneous laughter. Despite her anger and irrationality, Spinel is somewhat trusting.
