Ultimate Org Senki

Ultimate Org Senki (究極オルグセンキ, Kyūkyoku Orugu Senki, Thousand Demon, 49-51) : The King of all Orgs, the source of the Orgs' power after the Org Master was destroyed. Ultimate Org Senki was the final villain of Hyakujuu Sentai Gaoranger and was formed from the remains of the Org generals Highness Duke Orgs Shuten, Ura, and Rasetsu.

In the finale Senki was created when the Org Heart merges the remnants of the three Highness Dukes thus fufiling an ancient prophecy of the "Last Org Advent".

Stronger than Ultimate Org Hyakkimaru was, He overpowers the Gaorangers and destroys GaoGod and GaoHunter causing Shirogane's G-Brace Phone to disintegrate. He follows Shirogane to Animarium, destroys all but the original five Power Animals which then form into GaoKing, and then finishes GaoKing off destroying the other G-Phones and bringing the Animarium down. He then attacked the city. Since the Gaoranger witnessed him reform after failing to destroy him with GaoMuscle Striker, they realized that the Org Heart is his weakness and had to destroy it. Though Tetomu gave them an ancient sword to destroy Senki's heart, it was not enough. When all seemed lost the Rangers declare their humanity to Senki at which point the Power Animals are all revived and countless others arrive to help. They destroy Senki's physical form. The Gaorangers then uses the Hyakujuuken to destroy the Org heart so he could not revive himself.



The Highness Dukes' combined weapon, which is also Senki's default weapon, is the All-Carnage Ogre Blade. This weapon is the Highness Dukes' own version of the Gaoranger's Hyakujuuken, which is a combination of Shuten's axe, Ura's fan, and Rasetsu's fork and knife.
