well...
hes wearing a mechanical suit that is covered up under a coat the suit is to protect him from hazardous conditions... hes got a look of pain and misery yet remembrance the bits of ash in the air indicate that something has been destroyed
i think hes a lone survivor of an apocalyptical disaster on an alien world looking over a destoryed alien city that he once called home his suit can only stand so much radiation he must continue on his journey
