Anguis Masculus (アングィス・マスクルス Angwisu Masukurusu?, 5-6): A cobra Lord armed with a ceremonial staff named the Judgment Staff (審判の杖 Shinpan no Tsue?), his killing of Hisao Katahira attracted the police's attention. He later targeted Mayumi Katahira, with Makoto Hikawa stopping him until Agito arrives. Masculus was overpowered by Agito's Ground and Storm Forms until Femineus arrives and cover their escape. Masculus later tried to kill Mayumi again, accidentally completing Ryō's change. When Masculus attempted to kill Mayumi a 3rd time, he evoked the wrath of Ryo Ashihara when he assumes the form of Gills to fight him. While Gills isn't full powered at first, allowing Masculus to easily overpower him, Gills fully matures and proceeds to completely overpower the Lord. After pummeling Masculus into submission, Gills brutally kills the Lord with Gills Heel Claw.
