Gundam (Japanese: ガンダムシリーズ, Hepburn: Gandamu Shirīzu; lit. Gundam Series) is a Japanese military science fiction media franchise. Created by Yoshiyuki Tomino and Sunrise (now a division of Bandai Namco Filmworks), the franchise features giant robots, or mecha, known as "Gundam". The franchise began with the premiere of the anime series Mobile Suit Gundam on April 7, 1979, which defined the "real robot" mecha anime genre by depicting giant robots (including the original titular mecha) in a militaristic setting. .
