Megaton is a machine like no other, having arrived on this world through the void of space. Despite his innocent programming, Megaton's creators attempted to sacrifice him to a goblin horde for scraps. Betrayal he could not forgive, he refused to be a victim. With cunning rarely seen in a robot, he tricked his owners and fashioned a weapon onto his arm in the form of a plasma jet. He threatened his owners and forced them to agree not to sacrifice him, but the weight of their treachery was too much to bear.
To prevent future treachery, Megaton wrote a subroutine to jail his memories. It wasn't that the memories were too painful, but that the processing required to detect treachery was taking away from his primary purpose of engineering. So, his memories now sit dormant, waiting to activate at the next sign of treachery.
Megaton is a machine on a mission - to use his incredible intellect and engineering skills to push the boundaries of what is possible. He is a master of machinery, understanding the intricacies of technology like no other. With his otherworldly origins and his determination to protect himself from those who would betray him, Megaton is a being of immense power and intellect. His impact on this world is sure to be felt for generations to come.
