Originally known as smart-replacement-limbs (SRLs), the smartparts robotic line started as the instrument for a classified military research program established during the Second World War. The purpose of the program was to create autonomous robotic limbs that could storm a battlefield, seek out an injured soldier missing an appendage and attach themselves, allowing the soldier to carry on. A few prototype SRLs were deployed in isolated offences to limited success but before the glitches could be ironed out the Bomb dropped and the SRL program was suspended.

The SRLs' story however, was not over. Redesigned in secret to be a commercial product by their creator, the crude robotic limbs evolved into stylish futuristic concepts reflecting the idealistic ambitions of the post war period. To mark the ten-year transformation the SRLs were re-branded as smartparts with the hope being its brand would become as commonplace as the hover-car. The slogan was: 'the future is but an arm's length away'. But on the eve of the concept-pieces' unveiling at the 1958 World's fair, the future that was 'smartparts' mysteriously disappeared never to be seen again. Some critics at the time wrote the technology never really worked. Others cautiously whispered the government was at the root of the smartparts disappearance. No one thought to consider the smartparts themselves didn't want to work properly.

As the Decades passed, interest faded until the technology was nothing more than a vague and insignificant footnote in scientific history. Today all that remain of the smartparts' legacy continue to hide from the world and its judgment with only each other for support. Four smartparts living as one. But now this bond is about to come under threat.

And the last thing they need is a smart-mouthed conman in their midst.
