List of Marvel Comics characters: SSise-Neg is a fictional character appearing in American comic books published by Marvel Comics. The character first appears in ''Marvel Premiere'' #13 (January 1974) and was created by Steve Englehart, Neal Adams and Frank Brunner.
Sise-Neg (''genesis'' spelled backwards) is a 31st-century sorcerer who attempts to become omnipotent by time traveling back through history and collecting magical energy. While in 18th century Paris impersonating the magician Cagliostro, he encountered Doctor Strange, who was at the time searching for perennial foe Baron Mordo.
Despite opposition from Strange, Sise-Neg travels back to a prehistoric time on Earth when the demon Shuma-Gorath rules, and subsequently banishes the entity. Continuing to journey back in time, Sise-Neg reached the moment prior to the Big Bang that creates the universe and absorbs all the magic in the universe. Originally intending to recreate the universe in his image, Sise-Neg realizes that his quest to achieve godhood was pitiable, as reality is harmony and as it should be. He therefore decides to recreate the universe exactly as it was. Provided by Wikipedia
