Human: This is a toy prototype's skeletal structure. The Arms system consists of a four-legged high-speed mech with interchangeable limbs and parts that allow you to create your own unique mechs... in time. The Arms acronym stands for Automatic Robotic Mobility System, originally designed by the Galactic Union for combat purposes. However, three thousand years into the future, this technology has evolved to prioritize labor and sporting applications during peaceful times.
