The term "Mech" is an abbreviation for "Mechanical". It refers to a type of fictional humanoid robot or vehicle that appears in various science fiction works, particularly those set in a future where advanced technology and weaponry are commonplace. Mechs can range from small, human-sized machines controlled by a single pilot, to massive structures several stories tall, requiring multiple pilots or even entire teams to operate effectively. They often feature heavily armored exoskeletons, powerful weapons systems, and advanced AI technology that allows them to function autonomously in combat situations. The term "mech" is also used more broadly to refer to any type of machinery or equipment, regardless of its size or intended purpose.
