Roger was born on an unnamed planet in AD 410.[14] Although Roger has shown an affinity for the cold,[15] has remarked that snow reminds him of his home world and that he learned to ice-skate there,[16] Roger's planet and species are never specifically named nor seen. Roger also has purple blood (green blood in an earlier episode) and has on one occasion demonstrated to be capable of moving at superhuman speed (slowing down time and moving at normal speed).
It is also revealed that he records an individual's memories after sexual fingering. On his home planet, Roger worked as a greeter at a Wal-Mart-style department store. Roger was tricked into coming to Earth as a crash test dummy under the assumption that he was "The Decider" and that the fate of mankind was in his hands. In the course of learning his true purpose for coming to Earth, he learned he was very resistant to fire. Having survived the crash he has been on Earth since 1947, Roger has been a part of several important moments in recent American history. Roger had a hand in inventing disco music, was a member of the Miracle on Ice 1980 US Olympic men's hockey team, drove Phyllis Diller to two of her first three abortions in the '60s (with Roger feeling bad that Diller never got her driver's license), was Jerry Lewis's tailor in 1966 and gave him the idea for the MDA Telethon which Lewis took full credit for, fought for the Viet Cong during the Vietnam War, and was responsible for the death of Notorious B.I.G. in 1997 after angering an armed driver who cut the rapper off in traffic (Roger survived the shooting and stole the Notorious B.I.G.'s gold chain, which Stan assumed was a gift Roger made for him). He is also responsible for getting the captain of the oil tanker Exxon Valdez drunk, leading to the Exxon Valdez oil spill, and for creating the initial design for Jar Jar Binks for George Lucas for Star Wars Episode I: The Phantom Menace, as seen in flashbacks in You Debt Your Life. He has also had several one shot jobs such as car salesman and college professor as well as showing a number of talents for things like house cleaning, cooking, bartending, wedding planning and in general, the ability to organize large scale projects; like a massive spring break blowout, very well. Additionally, he is skilled in the art of disguise; being able to pass for either a man or a woman and to adopt an accent as required.
