Dai Satan

Dai Satan (大サタン Dai-Satan, lit. "Great Satan") is a villain in Kyouryuu Sentai Zyuranger.

He is a floating blue head of an evil god, and the series' "big bad". He tried to use Bandora to destroy the world 170 million years ago, but was banished to another dimension by Ultimate Daizyujin. He isn't actually mentioned (nor does he appear on screen) until Bandora summons him again in episode 30 to power up the monster of the week. He is destroyed along with Dora Talos at the end of the series by Ultimate Daizyujin.
