Roger's Species

Roger is an alien living secretly on planet Earth since 1947, when he landed on Roswell, New Mexico. The names of his species and home planet have never been revealed, although he appears to belong to the species commonly addressed to as Greys. He is also known to behave like a stereotypical Grey, which includes abducing Humans and probing them, for example.

Biography and personality
The reason Roger came to Earth is completely unknown, although since he appears to make no attempts to return, it is possible that he is exiled or possibly marooned on the planet. All we know about Roger's homeworld is that it's a freezing land; with an average temperature 400 degrees below that of Earth and that is has large, Wal-Mart-like megastores where Roger once worked as a greeter.

Little is known about Roger's early years on Earth too. Although never revealing himself as an alien, he apparently became rich and famous for a brief time in the seventies, when he invented disco music after finding a cassette tape from the future, creating a time paradox. He played for the U.S. hockey team in the 1980 Olympics and fought in the Vietnam War. He also lived for many years in a laboratory in Area 51. At some point, after having his life saved by Roger, the CIA agent Stan Smith helped the alien to escape and let him live with his family. For the last four years, Roger has been living with the Smiths. His current situation can be easily compared to that of Gordon Shumway – hidden from the world, not allowed to leave the house except on disguise, and escaping from boredom by becoming an appreciator of some of the most pleasing aspects of Earth's culture, like television, internet forums, alcoholic beverages and junk food. Also like Shumway, Roger is quite clumsy and a regular source of trouble. Unlike Shumway, however, he is also arrogant and self-centered, which may be a biological trait of his species, since it has been shown that being nice is harmful for his metabolism. Later, he turned into skiff that time in Planet 51.

Whenever Roger goes outside he has to wear a Human disguise, something which he enjoys a lot. It has been hinted that playing different characters while in disguises is a hobby adopted by Roger to help him escape from the boring reality of being stranded on Earth. It is possible that the whole situation is slowly driving him insane, as he once admitted that he doesn't "know what's real anymore". However, since Roger is known for his dramatic reactions, it is possible that the statement was just an exaggeration. He also owns a Yautja costume.

Biology
Roger's species seems to be hermaphrodite. They have fire-proofing skin and no bones in their arms, which makes Roger an excellent drummer. Perhaps most peculiar of all is that they seem to excrete heaps of gold and precious joys, something which is not considered valuable on their planet, naturally. To make it even odder, there seems to be some kind of supernatural curse regarding these excrements, as anyone who possesses them will have bad luck.
