Reiji Nogi is the human form of the Cassis Worm, who loves to feel nettlesome to the Riders in Kamen Rider Kabuto.
Nogi is an even stronger Executive Worm, entering the scene after Uca Worm was destroyed. He was followed by six subordinates. He has the "Life of Immortality" ability, which enables him to evolve into a stronger form each time he gets defeated. Each of his forms has natural fighting ability and a unique power of his own. He was eventually destroyed as Cassis Worm Clipeus.
All Kamen Rider vs Dai-Shocker
Reiji Nogi have revived once again and he join part of Dai-Shocker army.
Cassis Worm Dimidius: The first form is Cassis Worm Dimidius. His unique power is "Freeze" or the ability to stop the flow of time to the point in which even the power of Hyper Clock Up is purposeless. He was defeated by Hyper Kabuto's Maximum Hyper Cyclone.
Cassis Worm Gladius: The second form is Cassis Worm Gladius. His power in this stronger form is advanced into "Absorb" or the ability to absorb other Worms and tachyon energy to gain their powers. He can only absorb tachyon energy sequencially. Simultaneous application of tachyon-based attacks will result to neutralization of the absorbed tachyon. He was weakened by Kabuto, Gatack and Kick Hopper's (Triple) Rider Kick and ultimately defeated right after by Hyper Kabuto's Maximum Hyper Cyclone.
Cassis Worm Clipeus: The third form is Cassis Worm Clipeus. His power in this form is "Clone" or the ability to split himself into two entities. In addition to the blade arm gained in the previous form, he now gets armored plates and shields across his body. The first copy was destroyed by Gatack's Rider Kick, while the second one was destroyed by Kick Hopper's Rider Kick and Punch Hopper's Rider Punch.
