A picture of Roger visiting Scandinavia
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 abducting Humans and probing them, for example.
Biography and personality
Little is known about Rogers early life aside from a few stories and flashbacks. His home planet apparently features flying cars on tracks, he went to summer camp with Kang and Kodos and apparently killed and ate his father. He use to be in a relationship with his planets ruler Emperor Zing but cheated on him with a human male.
The reason Roger came to Earth was not revealed until Weiner of Our Discontent; he was apparently placed in a spaceship as a crash test dummy (but was under the belief that he was being sent to Earth to decide humanity's fate) and the spaceship was then deliberately crashed into Earth, at Roswell.
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 predestination 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 in 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.
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 hermaphroditic. They have fire-proof skin and no bones in their arms, which makes Roger an excellent drummer. Eating okra causes him to produce gases toxic to humans. When he is under excessive stress he can fall into a stress-induced hibernation cycle, causing him to appear dead for a few hours. Their bodies are also highly buoyant, allowing an adult male (Stan) to use Roger as a floatation device.There are orifices in his torso that can allow someone to reach in and simply grab organs. The pancreas can be taken out through these, though it doesn't seem to cause pain or urgency to be put back. Once removed, it seems to have a mind of its own, acting like a xenomorph chestburster. Perhaps most peculiar of all is that they seem to excrete heaps of gold and precious jewels, 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. During his reproductive cycle he secretes a milky mucus which is inexplicably delicious to humans. During this time they may release an egg from their mouth which may develop in the human body. He can also move extremely fast, almost making it look like time has frozen.
