Mecha

• 1. Introduction

  ›

  Mecha are giant robots or machines, humanoid walking vehicles that have captured the imagination of audiences across the world for over a century. The word itself is an abbreviation of "mechanical," first shortened in Japanese, where it originally encompassed any mechanism at all, from cars to computers to firearms. But outside Japan, the term narrowed to something more specific: colossal piloted machines, usually humanoid, towering over ordinary human beings and distinguished from conventional vehicles by their biomorphic, life-like appearance.

  What makes a mech different from a tank or a spaceship? The cockpit. Mecha are piloted from within, typically from a cabin lodged in the chest or the head, giving the operator the sensation of wearing the machine rather than simply driving it. They are not the form-fitting powered armor of Iron Man's suit; they are something far larger, closer in spirit to the Iron Monger who served as his enemy, or the mobile suits of the Gundam franchise.

  How did this idea go from a novelty in Victorian-era fiction to one of the dominant visual languages of global popular culture? And what does it mean that, in 2020, a Gundam-inspired machine sixty feet tall with fully functional articulation was put on public display in Yokohama? The answers stretch from an 1868 American novel to the workshops of Japanese engineers, from the imaginations of manga artists to the labs of a Canadian company that built a four-legged mech intended for competitive sport.

  ›

  Edward S. Ellis wrote The Steam Man of the Prairies in 1868, giving readers what may be the earliest ancestor of the mech in modern fiction: a steam-powered mechanical man, piloted from behind. Jules Verne followed in 1880 with The Steam House, which presented a steam-powered mechanical elephant carrying passengers across the landscape.

  H. G. Wells pushed the concept further in 1897 with The War of the Worlds, where his alien invaders moved on tripod fighting-machines whose motion he described with unsettling vagueness: "Can you imagine a milking stool tilted and bowled violently along the ground? That was the impression those instant flashes gave. But instead of a milking stool, imagine it a great body of machinery on a tripod stand." Wells never fully described how the tripods walked, which made them stranger and more frightening.

  In 1936, Jerry Siegel and Joe Shuster, the creators of Superman, included mech-like machines in a Federal Men story arc called "The Invisible Empire," serialized in New Comics issues 8 through 10. Around the same period, the Brazilian comic Audaz, o demolidor ran from 1938 to 1949, drawing inspiration from the Mexican comic Invictus and created for the supplement A Gazetinha of the newspaper A Gazeta. Robert Heinlein contributed two important entries: the waldo concept in his 1942 short story "Waldo," and the Mobile Infantry battle suits in Starship Troopers in 1958.

  ›

  Ogon Bat, a kamishibai storytelling format that debuted in 1931 and was later adapted into anime in 1967, introduced what may be the first piloted humanoid giant robot, though it appeared as a villain rather than a hero. The first humanoid giant robot piloted by the protagonist appeared in manga in 1948, and the manga and anime Astro Boy, introduced in 1952, gave the giant robot genre its most influential early humanoid protagonist.

  Tetsujin 28-Go, introduced in 1956, featured a robot controlled externally by remote, rather than from within. That distinction mattered enormously. When Go Nagai created Mazinger Z in 1972, he changed the formula by placing the pilot inside a cockpit within the robot itself. Nagai explained his thinking plainly: "I wanted to create something different, and I thought it would be interesting to have a robot that you could drive, like a car." Mazinger Z's pilot flew in via a small aircraft that docked inside the robot's head.

  Mazinger Z also pioneered die-cast metal toys, spawning the Chogokin series in Japan and the Shogun Warriors in the United States. Two years after Mazinger Z debuted, Go Nagai and Ken Ishikawa introduced Getter Robo in 1974, launching the concept of combination mecha, where separate units slot together to form a single super robot.

  Mobile Suit Gundam in 1979 then shifted the genre's center of gravity toward what became known as real robot anime, featuring mass-produced machines used in wars rather than mythical one-of-a-kind creations. The Super Dimension Fortress Macross in 1982 reinforced that template and would become the basis for real robot storytelling going forward.

• 4. Transformation and Franchise

  ›

  Shoji Kawamori pioneered the transforming mech in the early 1980s, designing machines that could switch between a standard vehicle form and a fighting robot. His first major step was the Diaclone toy line in 1980, followed by the Macross anime franchise in 1982. Kawamori's most iconic designs include the VF-1 Valkyrie, which appeared in both Macross and the North American adaptation Robotech in 1985, and Optimus Prime, known in Japan as Convoy, from the Transformers franchise that arrived in North America in 1986.

  The scale of these franchises in Japan became enormous. Series like Gundam, Macross, Transformers, and Zoids generated hundreds of different model kits. Robot anime, called mecha anime outside Japan, is among the oldest genres in the medium. The personification of its global reach can be seen in life-sized statues of Mazinger Z, Tetsujin, and Gundam built at various locations around the world.

  Mecha size in anime varies wildly across franchises, from machines barely taller than a tank in series like Armored Trooper Votoms to city-sized ships in Macross, to planet-sized forms in Getter Robo, to entities described as large as universes in Tengen Toppa Gurren Lagann: Lagann-hen and Demonbane. Not all mecha in anime are purely mechanical; some have biological components for interfacing with pilots, such as the units in Neon Genesis Evangelion, Eureka Seven, and Zoids.

  ›

  Mechagodzilla, created by Toho, first appeared in the 1974 film Godzilla vs. Mechagodzilla as a giant extraterrestrial robot built to kill Godzilla. In Guillermo del Toro's 2013 film Pacific Rim, humans pilot massive machines called Jaegers against Kaiju monsters that emerge from the Pacific Ocean. James Cameron's 2009 film Avatar deployed mecha called Amplified Mobility Platforms, abbreviated AMPs, as military instruments.

  In video games, mecha appeared as early as 1983, in Sesame Japan's side-scrolling shooter Vastar. Hideo Kojima's Metal Gear series, which ran from 1987 to 2018, built its entire premise around prototype nuclear-capable bipedal tanks called Metal Gears. The MechWarrior series launched in 1989 and continued through 2024, drawing from the Battletech tabletop universe. FromSoftware's Armored Core series, which began in 1997, placed players in the role of mercenaries piloting customizable mecha in distant post-apocalyptic settings.

  Squaresoft's Front Mission series, spanning 1995 to 2019, used real robot-style mecha in turn-based tactical scenarios. One Must Fall, running from 1994 to 2003, holds the distinction of being the earliest fighting game to feature an all-mech roster. Respawn Entertainment's Titanfall in 2014 and its 2016 sequel made a unit called BT-7274 into one of the more emotionally resonant mech characters in the medium's history.

  In StarCraft, across the full franchise running from 1998 to 2017, Terran forces can field eighteen different walkers and Protoss forces can field twenty-one, making walkers a structural feature of the game's tactical vocabulary.

  Suidobashi Heavy Industry unveiled the Kuratas in 2012, a driveable prototype mecha that became one of the most widely recognized real-world examples of the concept. In December 2016, Korean company Hankook Mirae posted footage of their bipedal prototype METHOD-01, designed by Vitaly Bulgarov. Also in 2018, Japanese engineer Masaaki Nagumo from Sakakibara Kikai completed a functional bipedal mecha inspired by Gundam, standing 8.5 metres tall and weighing approximately 7 tonnes, with fully functional arm and leg servos.

  The Gundam Factory Yokohama unveiled a sixty-foot mecha with full articulation on the 19th of December 2020. It remained on display until the 31st of March 2024, after which its remains were transported to Yumeshima Island and unveiled at a ceremony on the 23rd of October 2024, repurposed as a statue for the upcoming Osaka-Kansai Expo.

  In Canada, Furrion Exo-Bionics unveiled Prosthesis: The Anti-Robot in 2017, invented by Jonathan Tippett. The machine weighs 3,500 kilograms, produces 200 horsepower, runs on electric power, and moves on four legs across all terrain. The pilot controls it from inside using a full-body exo-skeletal interface. In 2020, Prosthesis received the Guinness World Record as the world's largest tetrapod exoskeleton. In 2023, the Japanese startup Tsubame Industries added ARCHAX to the list, a 4.5-metre-tall four-wheeled robot developed for commercial use.
