Instant way to improve Steven Universe: Pearl got into the Goth subculture not long after Rose committed ego suicide, and never left it. Her room in the temple is dark, she listens to Bauhaus, The Cure, and Siouxsie Sioux. The only thing she consumes are clove cigarettes, which she stockpiled in the Temple.
Why is she like this?
Her 8 foot tall, 69-inch bust life partner was stolen then fatally knocked up by the era's equivalent of a homeless SoundCloud rapper. Whom she eventually falls for as well.

Pearl is hotter as a goth who smells heavily of cloves and listens to The Cure.
