Fully equipped with his powerful new armor, Karmatron rushed then to Planet Metnal to save his brother, but he arrived too late. Emperor Asura tortured Nazul at his leisure, and then the dark emperor dumped him into Metnal's dreaded Darkness Zone, a place full of twisted, voracious man-eating beasts. Karmatron arrived at the Darkness Zone only to find the mangled corpse of Nazul still being devoured by the monsters who dwelled there. He also discovered that the evil emanations that impregnated the entire planet Metnal were very noxious to him (actually, evil in general was very noxious to him, because he used good spiritual power to fuel his powers) so he could only managed to escape rapidly from that horrid place with his brother's remains in his hands. Asura caught a glimpse of this awesome steel giant that came to his planet, and he became violently enraged then, for he acknowledge him for what he was, and knew him to be the source of many future problems.
