A humanoid race best known for their skin and hair colour (which can range from bright red to pink) and their aversion to all things labor, the Zeltrons are a humanoid species from the planet Zeltros in the Outer Rim. While most Zeltrons are in excellent physical shape, due to a metabolism that allows them to eat even the richest of foods, as a race most are extremely lazy. Since the entire planet has been converted to a pleasure world, work is seen as unnecessary, and so has been declared as an offense by the Monarchy. If anyone wasn't having a good time on Zeltros, the Zeltrons would certainly know of it, and would do their best to correct it.
Biology and appearance
Considered highly attractive and desirable by most humanoids, the Zeltron race possesses two special biological traits. One is that all Zeltrons can produce pheromones, similar to the Falleen species, which further enhanced their attractiveness. The second trait was their empathic ability, allowing them to read and even feel the emotions of others. Because of this ability, "positive" emotions such as happiness and pleasure became very important to them, while negative ones such as anger, fear, or depression were shunned.
An additional trait of them is the ability to project emotions onto others, creating a type of control. 
Society and culture
Their attitude to emotions in turn has influenced their culture, which is largely based on sexuality and the pursuit of pleasure. Most of their art and literature is devoted to the subject, bringing the galaxy the term, lustier than a barrelful of Zeltrons. Zeltrons are known throughout the galaxy as people to have fun with. Unfortunately, the Zeltrons think so too. Many a Zeltron has been known to follow other spacers and adventurers for years in a type of love-lust. On encountering a Zeltron, many spacers remark that he/she seems extremely familiar. It has been speculated that this is a side-effect of the pheromones, but no scientific proof has surfaced.
The Zeltrons looked upon monogamy as a quaint, but impractical, practice. They were also very gifted with holograms, and were the creators of Hologram Fun World. Their Elixir of Infatuation was notorious for its powerful amorous effects. 
Zeltrons were known to dress in wildly colorful or revealing attire. It was common to see Zeltrons wearing shockingly bright shades of neon colors in wildly designed bikinis, or nearly skin tight clothing of other sorts with bizarre color designs, patterns, and symbols.
