Zeltrons are a near-human species with a distinctive skin tone ranging from light pink to deep crimson, which can turn to a deeper hue when they become angry.

They have two livers and an incredible metabolism and are therefore usually in excellent physical shape. They produce pheromones, which often enhances their attractiveness and likeability to many other species.

Feelings of happiness, love and pleasure are very important to them and most of their art is devoted to sexuality and the pursuit of pleasure in general. They are gifted sculptors and hologram artists.

Their first inclination is to love, but fighting is a sport to them as well, making a Zeltron in the grip of enthusiasm a formidable enemy.
