Earth Curiousities Beast Anagmas is a wise beast in service to the Underground Empire Tube who knows nearly everything and a major antagonist in Hikari Sentai Maskman. He is the only one allowed to access Tube's ancient library and read its sacred documents.
He was voiced by the late Takuzou Kamiyama.
As the Tube Empire prepared for invasion of the surface world, Anagmas gave a speech proclaiming Tube's superiority and praising Tube's new ruler, Emperor Zeba.
When the Tube Empire faced resistance from the Maskmen, Anagmas hatched two plans to defeat the Maskmen, one by using the enhanced Imperial Beast Igara Doggler and another by using Dokuro Doggler to destroy the Maskmen's Great Five Robo.
When the Maskmen uncovered Zeba's identity, Anagmas attacked them to keep Zeba's true nature a secret. He was destroyed by Jet Cannon, but was enlarged by Okelampa to fight the Maskmen's Galaxy Robo, only to be destroyed again.
