Satasata (サタサタ SataSata?): A black Santa Claus-suited Fushigi Beast who posed as "Satan Claus" and visited all the boys and girls to take their presents and then creates an anti-Santa cult, converting children into his masked followers to commit acts of violence. After freeing the children from Satasata's influence and forcing him into his true form, Shaider chases the Fushigi Beast into the Fushigi Dimension and destroys him with Shaider Blue Flash.
