Dai-Satan (lit."Great Satan")is the ultimate evil in the Zyuranger universe, a giant floating blue-skinned head. He used the Witch Bandora to try to lay the Earth to waste 170 million years ago and uses her again to finish the job. He was banished by Ultimate Daizyujin back in the past.
Bandora invokes Satan and his power whenever she does evil; initially doing so to gain his blessing in accomplishing her mission during the Dora Sphinx incident. She invokes him again when using a ritual to allow for the fairy boy Ryota to reawaken vengeful warrior Burai in the present.
In the series, Bandora uses Satan's Tower to summon her master to help upgrade her Zombie Franke into Satan Franke. After Satan Franke was killed by Zyutei Daizyujin, the Zyurangers used Ultimate Daizyujin to defeat Great Satan, but he escaped.
In the finale, Great Satan brought Bandora's son Kai back to life to cement the deal. After Bandora used her magic to make King Brachion sink into the ground, she used Satan's Tower to summon her master once again and helped to recreate Dora Talos, who Kai used to severe Daizyujin's left arm and half of Dragon Caesar's tail.
Great Satan was finally killed by Ultimate Daizyujin in the finale just before doing away with Kai and Dora Talos forever.
