Loki is a fictional Marvel Comics supervillain and the adoptive brother and archenemy of the superhero Thor. He is based on the being of the same name from Norse mythology. The character first appeared in Venus #6 (August 1949) and was created by writer Stan Lee, scripter Larry Lieber, and penciller Jack Kirby.
In 2009, Loki was ranked as IGN's 8th Greatest Comic Book Villain of All Time.
Loki made his first Marvel Comics appearance in Timely Comics' publication Venus #6 (August 1949), where Loki was inaccurately featured as a member of the Olympian gods exiled to the Underworld. He made his first official Marvel appearance in Journey into Mystery #85 (October 1962), where Loki was reintroduced by brothers and co-writers Stan Lee and Larry Lieber and he was redesigned by Jack Kirby. Loki has appeared in various issues of Journey Into Mystery, Thor, The Avengers, and several other Marvel Universe titles.
Marvel eventually found the character popular enough to let Robert Rodi proceed with writing a 4-issue miniseries, Loki (July–October 2004), that features a different look at the character. The miniseries features painted covers and interior pages by artist Esad Ribic.
