Pretentiods are a race of humanoid hipster beings, that are smug, self centered, and look down on the rest of the "lame" universe.
Their culture is based on following "undergroud" ideas and culture, unless it spreads to neighboring planets Darkon, and Lumos, in which then they will no longer consider it cool enough for them. Their primary mode of space flight is old flying saucers that have been out of style since Glugbups were still a threat and not a laughing stock. They listen to old music, where outdated fashion, and grow much facial hair. Of course this would all change if they actually realized that this is not any form of rebelling whatsoever, but rather a poor attempt at filling an empty void in their life left by the fact that nobody in the galaxy actually gives a crap about them, their planet, or there lifestyle.
