Ep. 33: Kotona and Ra Kan face Bio-Kentro while Sword Wolf is damaged and crashlands.
Kotona and Ra Kan stop to refuel their Zoids. Kotona defends a helpless citizen against Digald soldiers and soon finds herself attacked by Bio-Kentro. Ra Kan comes to her aid, but Sword Wolf is badly damaged. Kotona attempts to airlift it to safety, but Rainbow Jerk is hit and crashlands. Ruuji's group arrives to help out, just in time to save Ra Kan and Sword Wolf from Bio-Kentro. Hayate Liger enters the battle, but Ruuji is unable to overcome Bio-Kentro even with the help of Ron's new Bamburian and Mii's Lance Stag, until his Liger transforms back into Murasame Liger, making a large and deep cut over Bio-Kentro's left front leg. After the battle and hearing that Zairin is still alive, he understands that he needs to become stronger and an image of "Mugen Liger" comes forth.
