A mechanical weapon in the shape of a person that appeared from another world. After they failed to destroy their target, her master retrofitted her with new technology. She started making adjustments of her own to her power nucleus as a last-ditch effort to thwart their enemy. However, it failed to activate when her master was in grave danger during the war with the gods. Knowing her master was aware of this, she vowed to protect her on her own, without the use of fancy technology. This in turn made her all the more stronger.
