mech or mecha 

Giant robot. Refers to humanoid types seen mostly in animé (Japanese cartoons) and Japanese games (i.e. Armored Core). Mechs/mecha can be anywhere from 30 to a few hundred feet tall and are usually pioleted by people. They can be used for many things, like constuction for example, but more often warfare.

The mech picked up the car and threw it at the V.I.P.
