Garanda Empire
Garanda Empire monsters are all based on animals, archnids and insects and are called "Jųjin" (Beastman). The Garanda Empire monsters were:
Episode 15: Beastman Bee (height 193cm, weight 102kg)
Episode 18: Tiger Beetle Beastman (height 210cm, weight 150kg)
Episode 21: Sea Anemone Beastman (height unknown, weight unknown)
There is no Beastman in episode 24, Amazon battles Emperor Zero and Shin Emperor Zero. In this series no monster appears more than once, except for Mogura Jųjin.
In episode 24 after he's killed Emperor Zero, Kamen Rider Amazon is confronted by a hooded figure, who is the true leader of both Geddon and the Garanda Empire. When Garanda Emperor removes the hood he looks exactly like Emperor Zero. He tells Kamen Rider Amaazon that he is Shin Emperor Zero, the Real Emperor Zero. The other one was a fake.
