Legend - S1.E28

Ruuji's group splits up and goes to find more rebels to help battle Digald. Ruuji, Mii, and Ron reach their first destination, and there they learn about the event called "God's Fury", which destroyed the previously advanced civilization of Planet Zi. Hearing an explosion outside the city, Ruuji goes to investigate, and is attacked by Zairin with his new Zoid, Volcano. Leeo weapons are unable to damage Volcano and Ruuji is forced to retreat.
