A mysterious and reclusive Dragon Slayer, Razlia the Twinflame is known as the Metal Demon, a technological monstrosity made up of millions of nano-machines. A beast of artificial life, Razlia's origins are unknown, as creatures such as himself are all but uknown to the inhabitants of the world.
It is said he met his end in combat with the Azorbian Priestess, Jenna.
A creature who does not value life as we know it. He is based off of one of the Gung Ho Guns from the Trigun manga with my own spin-- although he is probably a mash of more than one of them.
