"What? W-what is the meaning of this? What?"
―Ultimate Org Senki's final words before his death[src]

Ultimate Org Senki (究極オルグセンキ Kyūkyoku Orugu Senki) was the King of all Orgs, the source of the Orgs' power after the Org Master was destroyed. Ultimate Org Senki was the final villain in the last episodes of Hyakujuu Sentai Gaoranger and was formed from the remains of the Highness Duke Orgs.

Character History

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

Stronger than Ultimate Org Hyakkimaru, he overpowered the Gaorangers and destroyed GaoGod and GaoHunter, causing Shirogane's G-Brace Phone to disintegrate. He followed Shirogane to the Animarium and destroyed 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.

Senki's death

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 use the Hyakujuuken to destroy the Org heart so he could not revive himself.

Concept Art


to be added


  • The face on Senki's body is a mark of the merging of the three Highness Duke Orgs and the senses they represent: Shuten represents the touch and sight, Ura represents smell and hearing and Rasetsu represents the taste and speech.
  • Senki's wrists have armor/growths resembling the helmet of TsueTsue and the head of Yabaiba, while the body is colored similarly to their own; it is unknown why this is since they were not part of the fusion.
    • However, it could be a play on TsueTsue and Yabaiba having the possibility of having a child of their own.
    • Alternately, the costume was designed with the intent that they would be part of the fusion, when in reality they were killed beforehand; it is not clear if plans had changed or if the designer was unaware that they were not meant to be part of it.
