Daizyuzin's Last Day (大獣神最期の日 Daijūjin Saigo no Hi) is the twentieth episode of Kyoryu Sentai Zyuranger.
Bandora tempts the Zyuranger with multiple perils in order for them to summon Daizyujin for her ultimate plan for its destruction.
The day Bandora prophesized has arrived, and her gang start their havok into the city. Zyurangers, still without a clue about Bandora's prediction, hesitate to summon their Shugozyus. The sly Bandora puts the Zyuranger on the edge with a kidnapped school bus and the dinosaur eggs in her hands. Just when Zyurangers are to summon their Shugozyus, Barza, who finally has figured out the significance of the day, appears and stops them. Barza explains to the Zyurangers that this is the day of full eclipse, when the supply of Daizyujin's power source, the Gaiatron energy, becomes the least plentiful. The Zyurangers summon their Shugozyus to rescue the children captured in school bus and dinosaur eggs--although the chest of dinosaur eggs is once again lost in a river. When Daizyujin battles with Grifforzer and Lamy Scorpion, the eclipse begins and Daizyujin starts losing power. The Zyurangers and Daizyujin attempt to scatter their giant foes and escape, but just then DragonRanger grows giant with Bandora's evil power and fights against Daizyujin. Because Geki hesitates to battle with DragonRanger, Daizyujin loses the chance to escape. After the fierce onslaught from their giant enemies, Daizyujin powerlessly falls down, the Zyurangers fall out and each Shugozyu disappear into the lava.
