Who needs an Abrams tank when you can have a 100-foot man-shaped robot with a glowing sword and a fist that fires off like a missile? There's no argument - fighting robots are just infinitely cooler than ordinary vehicles. Whatever their shape, though, they are all known as "mecha". Mythology as a whole is also replete with artificial humans and similar automatons (eg. Talos, the great bronze automaton built by Hephaestus), but special mention goes to Hindu Mythology. One of the three barriers the gods set to protect their elixir, the Amrita, was a robot with rotary saws for hands.
