Ranghoul was sent by Zodiac to accompany lead scientist Kuzan in revealing the Gaia-Net to the world. He is attacked by Deathferd, and must use a Guyborg to help him. When later attacked by Guyferd, Ranghoul and his Guyborg maintain the upper hand and trap Guyferd with their staves. Deathferd then attacks them and poses such a threat that they must retrieve their weapons from Guyferd's trap, freeing him in the process. By working together Guyferd and Deathferd are able to defeat Ranghoul.
