Episode 31: The Giant Beast Stands Written by Junko Komura Directed by Noboru Takemoto
The Legendary Giant Beast, Cube Whale, has finally appeared. However, it attacks not only the Deathgalien and Bangrey but the Zyuohgers as well, in spite of them having the Great King’s Credentials. Sela and Misao, unable to chase after Cube Whale due to Cubal’s poison, have no option but to lie down at Mario’s place. Misao apologizes to Sela for dragging her into this.
Meanwhile, the Deathgalien have located Cube Whale. Ginis hands out the feared obliteration machine to Nalia. Cubal, then, passes that information to Bangrey.
