Break in! The Final Deciding Battle (突入! 最終決戦 Totsunyū! Saishū Kessen?) is the forty-seventh episode of Kyoryu Sentai Zyuranger, the first part of the four-part endgame arc. It features the return of Dai-Satan, as well as introducing Bandora's son, Kai, and his giant robot, Dora Talos.
Geki and Mei visit Satoshi, a sick boy who loves dinosaurs. To cheer up Satoshi, Geki tells him about the hatching dinosaurs eggs. Meanwhile, a strange quake hits Zyurangers' base and Bandora's Palace. Shugozyus tells Zyurangers and Barza that DaiSatan is re-emerging from hell and the time for the armageddon is approaching. Shugozyus also gives Barza a book of recorded written ancient language. In the meantime, an uncanny boy appears in Geki and Mei's way. Using his psycokinesis power, the strange looking boy abducts four children of Satoshi's friends. Later, the boy appears in Bandora Palace. The presence of the boy shocks Bandora--he is Bandora's deceased son, Kai. Kai informs Bandora and her gang about Satan's resurgence. Bandora brings her Bandora Palace down onto the Earth and declare the armageddon upon the Earth. Kai, along with hypnotized four children, rides colossal DoraTaros and assaults Daizyujin.
