Gundam is a science-fiction media franchise created by Sunrise in April 1979 that features giant robots (mecha) called "mobile suits" named "Gundam." Most Gundam are humanoid-shaped vehicles controlled from cockpits by a human pilot. 1979's Mobile Suit Gundam anime TV series defined the real robot genre of anime by featuring realistic gigantic robots in a militaristic setting.

The popularity of that TV show and the Bandai Gundam model kits, action figures, and other themed products that followed spawned a huge number of spinoffs, TV series, films, manga and novels, video games, and one of the biggest toy and hobby franchises in the Japanese toy industry.
