Screw Kid (スクリューキッド) is a screw-themed Perfect Choujin who served Big the Budo. He and Kendaman crashed the tag championships, quickly defeating Brocken Jr. and Wolfman. However, they lost their next match against Buffaloman and Mongolman. Fearing death for his failure, Screw Kid attacked Big the Budō to try to save his own life but was crumbled to dust by his master's power. He had the power to extend sharp drill bits from his hands and knees. He is voiced by Kaneto Shiozawa.
