Highness Duke Org Rasetsu

Highness Duke Org Rasetsu appeared in 2001 TV series called Hyakujuu Sentai Gaoranger. Highness Duke Org Rasetsu (ハイネスデュークオルグ ラセツ Hainesu Dūku Orugu Rasetsu) is the final Highness Duke to be awakened, a hermaphrodite with a mass of mouths which speak in both male and female voices. He referred to himself as the "Prince of Despair".

He is ravenous with an appetite for anything within reach, using a knife and fork as his weapons. He treats the Duke Orgs like dirt, painfully transferring their powers to certain Baron Orgs.

His very plan from the beginning was severing the ties between the Gaorangers and the Power Animals, using Kurushimemasu Org to obtain Kakeru Shishi's G-Phone to implant a bug-extension of him into it to pinpoint Gao's Rock. He had an alternate motive in kidnapping Tetomu, as he was obsessed with her cooking.

He almost got Tetomu as his chef, sacrificing Duchess Org Tsuetsue in the process while removing the Gaorangers from the picture, had the Power Animals not driven him away. Refusing to accept defeat, Rasetsu decides to complete his plan on Christmas, with his bug destroying the G-Phones prior to the fight while he smashes the G-Brace Phone.

Rasetsu then ingests his creation to assume giant size to destroy Gao Rock. But before Rasetsu can eat the gang, the Power Animals arrive, with GaoDeers restoring the Gaorangers' transformation devices. GaoMuscle and GaoHunter managed to wound the Highness Duke Org enough for GaoKentaurus to land the deathblow.

Rasetsu is later resurrected as the leader of the three Highness Duke Orgs, fighting GaoBlack and GaoBlue in a vain attempt to protect the blue idol within the lake that powers the barrier protecting the Matrix.

Though he was killed, TsueTsue uses the Org Heart to fuse him with the others to create Ultimate Org Senki.
