In the year 3002, humanity had endured countless cycles of destruction and reconstruction due to the unforgiving forces of nature. Amidst this perpetual struggle, construction teams had become a cornerstone of the economy, as they utilized heavy robots to expedite their work and defend against threats.
Jumbor was the esteemed leader of a renowned construction team in a small kingdom ruled by a beloved princess. While preparing to rebuild a tunnel ravaged by an earthquake, a superior construction team arrived and ruthlessly seized control of the land, leaving Jumbor and his friends to suffer.
After awaking in the year 3007, Jumbor discovered that he had been resurrected in a new, mechanically-augmented body cloned from his previous self. His robot arms were controlled by his brain's signals, and he was informed that his country and its rulers were gone. As the last of his kind, Jumbor found himself in possession of tremendous power.
