Sphene has an appearance similar to that of other Sphenes, as she is tall and lanky with four arms and messy hair. Her skin is deep yellow with stripes of orange, and she has four deep yellow eyes with black pupil, no nose (with her gemstone acting as a nose) and full lips. Her hair is light yellow and is shaped like an asymmetrical triangle. Her arms all sprout from her shoulders and are long and slim with slightly widening hands. Her gemstones are on her forehead and where her nose would be and are cool yellow and orange.
She wears a standard Homeworld uniform that’s tinted brown with a Yellow Diamond insignia on her chest.
