Mogurang (モグラング Mogurangu, 28, 37, 41 & Rider vs Shocker) – A mole monster. The emblem worn by the soldiers of the base that created it was a curved horned mole. He is able to move underground by digging quickly, with one of its hand replaced by a shovel while the other was a large claw. Hw was also equipped with two tentacle eyes, which allow him to spy from underground. He kidnapped a large number of people to turn them into human moles, but his operations were discovered by Rider #2. Using his digging abilities, Mogurang was able to defeat and capture Rider #2. However, Hayato escaped, and, in their rematch, Mogurang faced Rider #2 on top of a building. He was defeated by Kamen Rider #2's Rider Kick which caused him to fall onto a cement tank.
Mogurang was back in action later, episode 37, participating in an operation to kidnap children and test a poisonous gas on them. However, Kazuya Taki saved the kids and released the poisonous gas on Mogurang and its companions, destroying them.
Mogurang later returned under Doctor Shinigami, working alongside Armadillong to capture Kamen Rider #1. Even with their combined efforts, they could not beat Kamen Rider #1, but attracted him to Ghoster, who captured him.
Mogurang returned yet again in Kamen Rider vs. Shocker, where he helped Fly Man and Saboteguron face Kamen Rider #2. Mogurang appeared from rocks around Kamen Rider #2 and attacked, but was quickly destroyed when Kamen Rider #2 threw one of Saboteguron's bombs back to them.
