Kikkaijin Torafugun (in Japanese: 奇械人トラフグン Kikkaijin Torafugun, 5): A tiger puffer monster. His plan after possessing a random civilian was to taint the school lunches of elementary school students with his poisonous capsule pills.
After this, he targets a food delivery service to possess the workers and poison the nearby district. Apart from manifesting these capsules out of nowhere, his arms are metal blades and he can launch metal spike torpedos from his waist - mostly to impale targets.
One of his torpedos is redirected by Stronger's Electric Magnet to his shoulder, disabling said ability and letting him be destroyed by Stronger's Stronger Electro Kick.
