He could then form himself into solid steel and manifest different weapons as well as turn his puppets to steel. He built a puppet modeled after kurama. It was solid steel with nine, two meter long segmented tails and a human like upper body complete with opposable thumbs on it's clawed hands. it's body however was only a meter long.
