Bio-Particle Cannon - S1.E40

Zairin and an army of Bio-Zoids are dispatched to take back Torafu. They attack and successfully enter the city, and Volcano faces off against Mugen Liger. Zairin finds he cannot control his body and Volcano starts moving on its own. It activates its Bio-Particle Cannon to destroy Ruuji, but Seijuurou deflects the blast at the last moment. Zairin and the Bio-Zoids beat a hasty retreat.
