The Emperor's Final Challenge (皇帝最後の挑戦 Kōtei Saigo no Chōsen) is the thirty-fourth episode of Chouriki Sentai Ohranger. It is the conclusion of the two-parter introducing the Blocker Robo, featuring their combination into OhBlocker and the final battle with the leader of Baranoia, Emperor Bacchus Wrath.
When Bacchus Wrath emerges with his ultimate plan to crush the Ohranger, the team must learn to unite and transcend their hearts in order to master the ability to defeat the Baranoia leader.
Having survived the destruction of his underground facility, Bacchushund turned into a giant, he attacked the city with a giant sword he uncovered made of a special space metal. Yuji tried to stop him on his own with Blue Blocker, but he failed.
As the only solution is to combine the Blocker Robos and invoke the "ultimate sword", Chief Mirua has the Ohranger learn the secret of helm-splitting by practicing with swords to slice helmets in half perfectly in order to bring their hearts as one. Yuji's friend Mikio gets ahold of another sample of the space material that fell onto the Earth attempting to help Yuji become capable of defeating Bacchushund making him a Baranoia target, and though Yuji saved him, the sample was lost in the river. However, this allows Yuji to regain his faith in Mirua's training allowing the Ohranger team to master helm-splitting.
Later, the Blocker Robos combined to form OhBlocker and destroy Bacchushand's sword. With their training complete, Bacchushund was finally defeated by combining the Twin Blocken Swords for the "ultimate sword", the Twin Blocken Crash finisher.
Having witnessed his father's destruction, Buldont vows to make the Ohranger pay for this.
