Gotengo is a fictional super-weapon and submarine from the Godzilla franchise, first appearing in the film Atragon (also known as Kaitei Gunkan). It is not a human character, but a powerful advanced vessel built to fight invading forces and protect humanity. In later Godzilla-related stories, Gotengo is often portrayed as a key military asset used against giant monsters and extraterrestrial threats. Its role is typically that of a dramatic last-resort machine, symbolizing human ingenuity, courage, and resistance against overwhelming destruction.
