Yamaarashi-Roid (ヤマアラシロイド Yamaarashi Roido): A porcupine monster, whose human identity in the manga was Needle. He possesses the ability to produce quills that can be launched as projectiles or wielded as a weapon. In the original ZX magazine stories, which were published before the tv special, it's noted that he was the leader of Badan's cyborg troops, but that's never mentioned in the actual tv special.
