Card storylines

Card storylines are an unofficial term for the stories that can be pieced together regarding the relationships between certain monsters and groups of monsters from card artworks.

Many of these stories were detailed in the Japanese Master Guide books.

"Dark Ruler Ha Des"
Dark King of the Abyss was a very powerful king who ruled over darkness. Dark Ruler Ha Des first appeared when he dethroned Dark King of the Abyss and took control of everything evil. He was a merciless tyrant who built an entire army of shadow creatures. "Opticlops" and "Berserk Dragon" were apparently the creatures he valued the most. He was often seen having dealings with shady persons. Besides his army, he was extremely powerful by himself, being able to control the free will or destroy his enemies in many ways. However, he eventually lost control until one day he was confronted by his rival who fired a hate buster against him, possibly draining his very soul. The result of the battle was fatal for the Dark Ruler Ha Des. However, that wasn't meant to be the end, since he was revived, by the same plague that had turned many other monsters into zombies. At one point he revived Archfiend Zombie-Skull. Later he faced his nemesis and ultimately defeated it, thus ruling over darkness once again.

"D.D. Warrior Lady"
Originally a wandering outlaw, for some unknown reason she and Warrior Dai Grepher became rivals. During their fight, she was abducted to the Different Dimension. There she found comrades which helped her train herself in traveling between dimensions. Then, using the Different Dimension Gate, she was able to return from the Different Dimension along with some other creatures who were lost there. Upon her return, she engaged her rival in another fight, where she used her new powers to injure him, apparently beating him. Later, her rival returned for revenge in a darker form, but she banished him to the Different Dimension again. At some point prior to meeting Warrior Dai Grepher, she was allied with the Marauding Captain, using a Resonance Device to make their levels the same.

However, after that blast, Gagagigo was severely injured and was in need of immediate support. He went on to gain aid from Kozaky, who was a spy among the warriors, and got his body reconstructed, turning him into Giga Gagagigo.
