River of Mist - S1.E26

Torafu's defense force is sent to protect Atakka. Meanwhile, the rebels begin arguing amongst themselves. The Elephunder team heads out by themselves, and the other groups follow, each determined to be the first to reach Torafu. Split apart, the rebels make easy prey for Zairin's Bio-Zoids. When Zairin learns that Ruuji has arrived, he heads out with Mega-Raptor to fight him. Murasame Liger transforms into Hayate Liger and defeats Mega-Raptor, also breaking the dam that kept water out of the River of Fog. The water flows down the river and washes away the Bio-Zoids.
