Ultimate Org Senki

Ultimate Org Senki was the final villain of GaoRanger he was formed from the remains of the Org generals 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 propercy.

He overpowers the Gaorangers and destroys GaoGod and GaoHunter causing Shirogane's G-Brace Phone to disintegrate. He follows Shirogane to Animalium, destroys all but five Power Animals which form into Gaoking destroying the other G-Phones and bringing the Animarium down. He then attacked the city. When all seemed lost the Eangers declare their humanity to Senki at which point the Power Animals are revived and destroy Senki's physical form. The Gaorangers then uses 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.
