An AI-equipped combat armor. Though well capable of independent action (combat and otherwise), his true power shows when aided by a human controller in his cockpit. Powered down for 1000 years after Elmedine killed his original pilot. Kind and likable. 

In the year 3195, there was a war between an army of robots and the humans. When Shaian, a sentient combat armor, lost his companion in battle, he shut down until his internal systems spotted a new human. It's now almost a 1000 years later, and Shaian's greatest enemy is still alive and doing battle in Brazil. With a new friend`s help, Shaian may be able to stop this evil force before another war rages over the continent.
